Emotion Regulation of LED Solar Street Lamp Manufacturers in Selecting High-quality Sales Market
If solar street lamp manufacturers want to develop the trend, they must encounter the problem of selecting the sales market. How to select the high-quality sales market is the key difficulty encountered by many LED solar street lamps, and there are few practical ways. The sales market selection of solar street lamp manufacturers must be different from that in China and overseas, Select suitable regions to carry out marketing promotion according to the specific situation of each enterprise.Solar street lamp manufacturers must have a careful attitude towards commodities. Under China's large market environment, many solar street lamp manufacturers have long cultivated the bad habit of low-cost market competition. More and more low-cost commodities are filled in the sales market. The quality of such commodities is obvious, When customers buy LED solar street lamps, they must prevent such cheap goods. The quality is worrying.Solar street lamp manufacturers are changing, and led solar street lamps are also developing continuously. Solar street lamp manufacturers should continue product research and development, produce and manufacture new LED street lamps, and be good at independent innovation. Otherwise, they can't consider the increasing requirements of customers and engineering projects, and the difficulty coefficient of product research and development is higher, Independent innovation must be a difficult road.

But how does it work? How to choose and use it well? With iDLights.com, take advantage of its assets and offer yourself 100% ecological lighting. Running on solar energy, the batteries of the outdoor solar lights are recharged during the day to illuminate during the night. They work thanks to a system of LEDs and photovoltaic sensors, which store the energy under the effect of the sun and restore it when the night falls, turning on automatically thanks to a sensor of darkness. Practical to use and 100% ecological, the outdoor solar lights thus make it possible to light your garden without needing a connection to electric cables. There are 2 types of solar lighting: solar terminals, small size or street lamp, more or less 1 meter high, whose lighting power is stronger than solar terminals. Choose them according to the light intensity you need. How to choose the right outdoor solar lighting? There are different types of solar lighting: solar beacons, solar terminals, solar lamps, solar pavers, recessed solar spotlights. This type of lighting is aesthetic and ecological. How to find your way around and how to choose the right solar garden lighting? The luminous power of your solar lighting First of all, you must take into account the light intensity of the lamp. Know that it is better to rely on Lumens than Watts. Indeed, the lumens are a more reliable unit of measure, because the Watts is not revealing of the real luminous power, it is about the consumption, and the lumens vary according to the quality of the leads. It is important that the lamps in your solar lighting (lamps and photovoltaic panels) are ideally located. Avoid areas of shadows, even partial, at any time of day. It is the direct solar radiation that offers the possibility of recharging your lamps in an optimal way. Some lamps have an integrated solar panel. They must also be placed in sunny and open areas (no shade areas, no foliage, roof projections, etc.). Also, do not mount your solar lamps on a north side of the building. To equip your garden with quality equipment, remember to check the following points when you make your purchase: your outdoor solar light must be equipped with a long life battery, guaranteeing to run at least 8 hours after a day of charging. An important feature not to find yourself in complete darkness in the middle of the night. Also, choose a lamp of good power in order to benefit from a quality lighting (at least 12w). Opt for material with LEDs, resistant to water and thus to bad weather and provided with changeable batteries (if possible 2 or more interchangeable batteries). Depending on your wishes, choose lighting options that offer continuous or intermittent light intensity. The right options: lights with a presence detector (which lights up when you pass in front) and those with a UV filter to extend its life and avoid its degradation under the effects of sunlight. A solar lamp for the garden uses solar energy. It is, therefore, an ecological lighting mode that is easy to install and does not require any specific connection. However, to enjoy it as long as possible, it is essential to know how to choose it well. Before buying an outdoor solar lamp, check that its battery offers a good autonomy, i.e. an autonomy of 2 h minimum in winter and 10 h minimum in summer. Also, check that it has a power of at least 12 watts to ensure sufficient lighting. Choose a quality solar lamp with a good life, unlike a cheap lamp that will stop working after two or three years. Make sure that a solar garden lamp offers good weather resistance. For that, one of the best choices is the stainless steel solar lamp: this stainless steel will not rust and will be resistant in case of wind or hail. To avoid the solar lamp being constantly lit at night and to avoid generating light pollution, choose a model equipped with a presence detector. In this way, the lamp only lights up in the presence of a person. Solar lamp for the garden: combining design and robustness To ensure that a solar lamp fits perfectly into your garden, do not hesitate to choose a lamp with a design that matches your furniture, plants and garden style while being robust. Install your lamps according to your needs: to highlight the paths of your garden for example, or to illuminate you when you walk or drive by. The solar terminals are very simple to install: simply push them a few centimeters into the ground. Street lamps may require a little more installation time: they usually need to be saddled on the floor. If necessary, you can also apply them to the wall or on your terrace. The solar lamps adapt to all your desires. Just avoid places that are too shady, so that they can enjoy the sun, their essential source of energy. How to maintain your solar garden lighting? Garden lamps are simple to maintain: it is generally enough to clean the solar panel each season, in order to optimize their brightness and their lifespan. The batteries of solar garden lamps also need to be changed from time to time: usually every year on average. It is obvious that solar lighting works better in summer when the hours of sunshine are more numerous. But there are solutions so that your garden is also lit in winter. Some lamps are equipped with both a rechargeable lithium solar battery and an alkaline battery that takes over. These lamps are therefore hybrid. In winter, you can opt for solar lights with a motion detector. They are therefore only used occasionally, which preserves their battery capacity in the event of low sunlight. Whichever type of solar lamp you choose, solar lighting will enhance your garden at nightfall. Garden lamps may contain pollutants. Generally, it is necessary to return them to the manufacturer so that they can be recycled. They should not be thrown in your garbage can. Do not hesitate to ask your distributor for advice.

Solar Lights Aren't Working When My Electrical Lights Are On!!!?
It relies upon on the wattage that it needs. a gentle bulb has a lot, a lot less ability than direct solar does, yet for a gadget like a image voltaic powered calculator it is sufficient. once you attempt to ability your total homestead, a gentle bulb is genuinely not sufficient. somewhat than looking up its ability requirement for the ipod case and doing each and each of the calculations, it would want to be more suitable accessible to really attempt it and word if it somewhat works1. "Solar Plane" isnt that cool?if it's runnin on a solar panel then it do not need any fuel but that would be a different story if you are flyin on a plane with solar panels and it's a night. but I kno there are some cars like that but jus not that many & there's the electric car 2. but they really need 2 do somethin b-cuz gas prices r gettin 2 high.2. Another question about solar eclipses?Well, there are 2 sun eclipses a 12 months, someplace in the world. Where it's all depends upon wherein the umbras are. There are eclipse seasons every 12 months. This subsequent one might be in overdue august and early September3. What is the downside of community solar?Only power when the sun shines.Storage costs as much as the solarYou still have to keep all the conventional generation available for when the solar under produces.Still, we have to run the rest of the unity as if the solar was coming from traditional sources.The main advantage of community solar is less costly to install than rooftop solar on houses and reduced fuel consumption for a traditional generation. Does 5 help enough to justify community solar?4. What is the size relation between our solar system and the Milky Way?To put it graphically, if our solar system were the size of a CD, then the Milky way would be the approximate size of the Earth5. solar enegry?Solar energy is converted into heat energy and electric energy by utilizing solar panels and solar vacuum tubes through physic and chemical effect.Solar energy is more and more popular ,government encourage huamn to use solar energy,it is widely used in every country,also,solar enery will be the trend of energy6. About our solar system?Our solar system orbits the galactic centre, just like all the other solar systems/stars in the galaxy. It takes between 225 and 250 million years to orbit the centre once.7. coal vs solar energy? help?You could answer this any way you like, really, depending on how you address cost. On the one hand, once solar is operating, it is cheap. Not free because electronic things break down and need repair, you need to keep the panels clean etc. Once coal is operating, you need to keep buying coal and putting it on the fire. But think about the prior costs. There are the obvious ones like buying and fitting the solar panel. This is a cost. Many old homes have fireplaces where could could burn coal so probably not much of a cost there. Then there are the less obvious ones like how much it cost for society to advance to a state when it could make solar panels. How much it cost to research solar technology, build the factories, etc. Whereas coal you can dig up from the ground. Okay you have to mine it but really it is still just a hole in the ground. If you look at China you will see which is cheaper. Mainly, the Chinese burn coal. If solar was cheaper presumably they would do that. As would everyone else. But then there are the social costs, i.e. reduced life expectancy from smog, etc. How you price these up is anyones guess. But clearly coal has a greater social cost than solar where it is used.8. Simple Solar Setup questionThe charge controller will handle the current coming from the panel. As LsD mentioned, it should prevent overcharging, but check the manual via model number online if possible. It's essential you have the instructions on hand to ensure you do not fry the controller when hooking it up. Typically when the battery charge becomes close to 100%, the controller switches into a trickle charge mode.Hope this helps
Where Can I Find a Lighted Palm Tree?
I agree with going to Michael's. I got mine there a few years back and it is over 5' tall. I did not use solar lights because I wanted a showier look. I wrapped green Christmas lights in the palms and then used a rope light wrapped around the trunk to fit. It does not use much electricity because of the low voltage and you can put it on a timer for the amount of time you want. Wait until they have a 40% off coupon and they will be quite affordable1. My solar lights are probably 3 yrs. old.?HD and Lowe's will probably have them, batteries for sure, bulbs maybe. If they are good quality metal, then try to fix them. If they are plastic I would junk them and start over.2. anyvone know about outdoor solar lights?They have what is called a Photoelectric Eye, which senses electromagnetic radiation TRANSLATION: LIGHT! When the Eye sees no light, then it turns on3. Amazon is selling these flickering flame solar lights for £30.99Solar lights are one way to instantly transform an outdoor space. Affordable and low-maintenance but highly effective, you just charge them in the sun during the day to create a stunning light display in the evening. The StillCool Solar Flickering Dancing Flame Lights are the ultimate cosy lighting for autumn. Not only are they perfect for creating a warm ambience in your garden, but they wo not affect your electricity bills either. Candles are perfect for creating a cosy atmosphere, particularly in the autumn, but they are not the most practical for outdoor lighting. If you want to recreate that warm glow, the StillCool Solar Flickering Dancing Flame Lights are the next best thing. Safe and realistic, the lights have proved to be a big hit with Amazon shoppers. 'Fantastic value for money' wrote one delighted shopper 'The warm candle-like glow and imagery they give out are second to none! 'They are extremely realistic and give an excellent ambience to our rockery and water feature that they surround. I would 100% recommend these fantastic lights.' Another shopper wrote: 'These lights are amazing. My husband was unsure on solar lights to begin with, but he absolutely loves these lights. 'We have had lots of compliments from our neighbours about them. They are beautiful when they come on and look like candles burning away with the flicker.' To use, charge the solar lights in direct sunlight (it should take up to eight hours) then the solar panel will convert the sunlight into electrical energy, ready for ten hours of battery charge. As the sunlight is not as strong in the autumn and winter, you should get at least five hours in after fully charged. While shoppers say these lights create a 'warm, cosy light', it's worth noting that they are not super bright, so if you are looking for powerful lights, then you may need electric ones. One reviewer wrote: 'These are really beautiful in the garden at night. The amount of light they put out is minimal, but as a decorative light, they are perfect. The flicker effect is very good & they are much bigger than I expected.' With no cords or wiring needed, you can place the StillCool Solar Lights wherever you like. Use them the line your pathway, place them at the entrance to your garden or put them in the flower beds to create a lovely glow at night. Another customer raved: 'They look fantastic at night... They flicker very convincingly and look far more substantial than the usual filling station offerings. They are not cheap, but they are worth the money.'

Importantly, challenge-response pairs differentiate our protein-based PUFs from other common unique objects and tags29,63. In reaction to optical challenges, defined by a unique set of excitation and emission bands of different fluorescent proteins, the edible PUF made of silk protein (i.e., fibroin) and fluorescent proteins generates distinct output responses, which are used to extract digitized keys (Fig. 1a). The source of entropy is randomly distributed fluorescent silk microparticles seamlessly embedded in a covert thin transparent silk film. First, we take advantage of four different fluorescent proteins (i.e., eCFP, eGFP, eYFP, and mKate2) that have specific excitation and emission peaks in the visible wavelength range (Supplementary Table 1). Specifically, we utilize fluorescent protein-expressed silk produced by transgenic silkworms as recombinant proteins via the piggyBac transposase method (Supplementary Methods and Supplementary Fig. 1a). Silk proteins are an excellent biopolymer to be genetically hybridized with fluorescent protein genes46,55,57,59. Second, to fabricate fluorescent silk microparticles (Supplementary Fig. 2), fluorescent silk fibroin is regenerated into an aqueous solution with a low-temperature process, is freeze-dried, and is gently ground into zeolite-shaped microparticles with sizes of 99.3 7.9 m (mean standard deviation) (Fig. 2a, b and Supplementary Fig. 3). Third, an admixture of the fluorescent silk microparticles is broadcast on a large flat surface and a white silk fibroin solution is poured on top. After an ambient drying process in the dark, this thin transparent silk film with a thickness of 150 m is punched into 7 7 mm2 squares, resulting in all protein-based edible PUF devices (Methods and Supplementary Figs. 2 and 4). eCFP, eGFP, eYFP, and mKate2 silk cocoons possess bluish, greenish, yellowish, and reddish colors under white light illumination (Supplementary Fig. 1b). However, after the regeneration of the fluorescent silk, each type of fluorescent silk microparticles are not distinguishable in the naked eye, while maintaining their fluorescent properties (Fig. 2 and Supplementary Fig. 5). This fabrication process is scalable for mass production without using any sophisticated equipment and is safe for oral consumption without any organic solvents or synthetic polymers (e.g., methanol, ethanol, isopropanol, or polyvinyl alcohol) (Methods and Supplementary Fig. 6a). Analyses of mass spectroscopy, energy-dispersive X-ray spectroscopy, and in vitro cytotoxicity (cell viability test) assays support the overall nontoxicity of the edible PUF devices (Supplementary Methods and Supplementary Figs. 7-9). In Fig. 3, the flow diagram illustrates how a cryptographic key is extracted from an output response when challenged by a set of excitation and emission bands, including the raw output measurement, the bitstream extraction, and the final digitized security key. We mainly use four representative challenge-response pairs (n = 4) based on the excitation and emission peak wavelengths of the individual fluorescent proteins in silk (Supplementary Table 1 and Supplementary Fig. 1c). An input challenge (C ) is selected as a combination of the excitation and emission bands at specific wavelengths such as = 415 nm and = 460 nm; = 470 and = 510 nm; = 470 and = 560 nm; = 530 and = 630 nm, corresponding to eCFP, eGFP, eYFP, and mKate2 in silk, respectively. Upon optical excitation, a raw fluorescent image is recorded by a charge-coupled device (CCD) camera equipped with a conventional zoom lens via a tunable color filter (Methods and Supplementary Fig. 10a). In other words, the corresponding fluorescent image acts as an output response (R ). A resultant digitized key (K ) is obtained by an extractor that converts the fluorescent image of silk microparticles to a binary bitmap (Fig. 4). First, to improve the quality of binarization, we normalize the raw fluorescent image (300 pixels 300 pixels) by the maximum intensity (Fig. 4a). The noise is removed by applying a threshold of 20%. Fluorescent areas smaller than a specific pixel size of 20 are also considered as noise. Then, the image is resized to be 150 pixels 150 pixels with a binning process. Second, to ensure a low bit error rate (high reproducibility), we find the spatial peak position of each fluorescent silk microparticle where the highest intensity peaks of the microparticles are located, subsequently reducing the image size to 50 pixels 50 pixels (Fig. 4b). Then, the peak positions are only assigned to 1 bits and other pixels are 0 bits. Third, to remove the bias of 0-bits, we apply an enhanced version of the von Neumann bias compression algorithm with two-pass tuple-output debiasing (Fig. 4c)64. Because the fluorescent peaks are relatively rare events in the entire image due to the density of the fluorescent microparticles, global bias is present such that 0-bits are generated consistently more often than 1-bits. Finally, after debiasing, we use first 64 bits as a digitized key in each response, because a typical minimum number of peaks in the fluorescent images is 32. Combining four challenge-response pairs (n = 4) together, the final digitized key size results in 256 bits (=4 64). We assess the quality of randomness of the edible PUF-generated binary sequences, using the NIST statistical test suite that was originally designed to evaluate random and pseudorandom number generators65. One of the minimal requirements of PUFs is randomness with high entropy, as PUFs rely on an entropy source to create an unclonable output response66,67. When PUF responses are used for cryptographic key generation, it is also critical to evaluate the randomness to ensure the unpredictability of the keys generated by PUFs. The NIST statistical test suite includes 15 different tests to quantify the randomness of bitstreams. Each test focuses on a specific aspect of randomness (Supplementary Table 2). Some of the tests rely on the minimum sequence length of 1 106 and the minimum number of substrings (blocks) of 55, requiring a total stream of 5.5 107 bits. On the other hand, the key size of the edible PUFs is significantly shorter than those of random number generators. To use seven statistical tests that require a reasonable stream length, we explore the randomness of binary sequences summed from 30 different PUFs (Fig. 5). Specifically, we collect a total of 7680 bits from 30 different PUFs (256 bits for each PUF) and divide the bitstream into 60 sequences to perform each statistical test 60 times on individual 128-bit long sequences (Supplementary Dataset 1). Each statistical test returns two results; a p-value of a chi-squared (2) test and a pass rate (i.e., proportion), as shown in Table 1. As summarized in Table 1, the binary sequence from the 30 different PUFs passes all of seven NIST randomness tests without any post-processing. The parameter values used in each test and the characteristics of the NIST randomness tests are summarized in Supplementary Table 2. In other words, the bitstream (7680 bits) extracted from the 30 PUFs is statistically random, supporting the idea that the output responses of all protein-based PUFs can be unpredictable and unclonable. This result also supports the idea that our simple broadcasting process of particulate fluorescent silk offers a random spatial distribution as a straightforward yet effective entropy source60,61. To evaluate the basic PUF performance, we examine the digitized keys of the edible PUFs. We first estimate the bit uniformity by checking the equal probability of observing 1-bit or 0-bit states: where K is the lth binary bit of the key and s is the key size. Basically, the bit uniformity is the Hamming Weight (i.e., number of 1 bits in a binary sequence) of the s-bit key. For 30 different PUFs, the distribution of bit uniformity converges to the ideal value of 0.5 (Fig. 6a). Then, to evaluate the device uniqueness of each PUF, we calculate an inter-device Hamming Distance (HD) by counting a number of different bits between two PUFs under the same challenge. The device uniqueness measures the degree of correlation between digitized keys measured from two different PUFs. Ideally, the digitized keys from any two selected PUF devices should be uncorrelated, indicating that the state of a PUF is unknown even when the states of other PUFs are known. The inter-device HD between any two PUF devices can be defined: where K and K are s-bit keys of the ith PUF device and the jth PUF device among q different PUFs, respectively. The 30 different PUF devices generate a total of C (=30 29/2 = 435) comparisons. In Fig. 6b, the histogram of the normalized inter-device HDs is well fitted into a Gaussian distribution with a center at 0.5032 with a standard deviation (SD) of 0.0458, which is close to its ideal value of 0.5, exhibiting the excellent device uniqueness of all of the edible PUFs. In addition, we investigate the degree of correlation among the digitized keys of four responses in each PUF by calculating an average HD (Fig. 6c). The 30 different PUFs result in a mean HD value of 0.499 with a SD of 0.0041, indicating that the individual digitized keys in each PUF are also unique. When the number of challenge-response pairs is extended to seven, seven resultant digitized keys are still uncorrelated with a mean HD value of 0.5089 with a SD of 0.0766 (Supplementary Figs. 11 and 12). In addition, we calculate an encoding capacity of the edible PUF-generated binary sequences. The encoding capacity simply means a number of codes that can be generated and is defined as cs where c is the bit-level (c = 2 for binary bits of 0 and 1) and s is the key size38,68. To accurately estimate the encoding capacity, it is important to use an appropriate key size. When an imaging scheme is used, one may think that the total number of pixels (variables) is the digitized key size. In this case, the actual encoding capacity can be less than this nominal encoding capacity, because each individual pixel (variable) cannot be completely independent. One way for estimating the number of independent pixels (variables) is to analyze the degrees of freedom; s = p(1 p)/2, where p is the mean probability and is the standard deviation31,34. In Fig. 6b, the resultant width of the inter-device HD distribution shows that significant subsets of the key are mutually independent, corresponding to the degree of freedom (or number of independent variables) of 120 (0.5032 (1 0.5032)/0.04582). As a result, the edible PUF has c = 2 and s = 120, resulting in a relatively large encoding capacity of 2120 (1.3292 1036). Importantly, the debiasing process is useful not to comprise the actual coding capacity. If a security key is biased with too many 0 s or 1 s, the actual coding capability is often diminished. A large encoding capacity could be utilized to provide information on manufacturer-determined data, including dose information (e.g., dosage strength, dose frequency, and expiration date), manufacturing details (e.g., location, date, batch, and lot number), and distribution path (e.g., country, distributor, wholesaler, and chain). If a higher encoding capacity is required for a specific application, the key size of our edible PUF can simply be scaled by further optimizing the density of fluorescent silk microparticles, which allows for a larger number of peaks in each image. The number of challenge-response pairs can also be increased by incorporating additional combinations of the excitation and emission bands (Supplementary Fig. 11). To examine the feasibility for reliable PUFs, we test the readout reproducibility and stability of the security keys from the identical PUF device. The reproducibility of a PUF represents the ability of generating the identical keys following the same repeated challenges. We calculate an intra-device HD, which is quantitatively described by a bit error rate (i.e., percentage of error bits out of response bits with an ideal value of 0) from 10 challenge-response cycles (nine pairwise comparisons) for each PUF device. For the ith PUF device, an average intra-device HD captures the readout reproducibility: where K and K are the original s-bit reference key and a s-bit key extracted from the same PUF device at a different time-point t and m is the number of repeated measurements. Figure 6b shows a relatively low mean value of 0.0632 with a SD of 0.0164 estimated from the intra-device HD histogram for the 30 different PUFs at the same 10 challenge cycles. We further examine the long-term reliability under the same challenges after 60 days in the laboratory environment (i.e., stored at 22 2 C and 40-50% relative humidity in the dark) (Supplementary Fig. 13). When the fluorescent intensity of the raw fluorescent images taken 60 days apart is compared, the correlation coefficients (r) of the four responses (R , R , R , and R ) range from 0.833 to 0.983. For the pixel positions of the first 32 peaks in the binarized images, the r values are even higher than 0.895 for all of the responses. These results support the potential reliability of the protein-based edible PUFs, although the reproducibility assessments do not reflect extremely harsh conditions, given the medical applications. We further estimate a false positive rate and a false negative rate from the inter-device and intra-device variabilities. When PUFs are used for authentication, the false positive rate is the probability that PUF A is authenticated as PUF B. The false negative rate is the probability that a correct PUF fails to be authenticated. The resulting false positive and false negative rates are 9.6394 1013 and 3.0982 1012, respectively, assuming that the inter-device and intra-device variabilities follow Gaussian distributions (Supplementary Fig. 14). The pairwise comparison map of cross-HD analyses further shows that all of the 30 different PUFs are highly uncorrelated (Fig. 6d) where the diagonal line indicates the intra-HD values for the identical PUF device itself, while the off-diagonal points represent the inter-HD values compared with the other PUF devices.

But no matter how many advantages led solar street lights have, we also need to consider the lifespan of solar street lights. Due to that the solar street light is not cheap, but it brings long-term benefits. The lifespan of solar lamps is much longer than that of ordinary electric lamps. If you want to know the service life of solar street lamps, you must first understand the composition of solar street lamps. Solar street light is an independent power generation lighting system, which is composed of batteries, street light poles, LED lamps, battery panels, solar street light controllers and other components. During the day, the solar panel converts light energy into electrical energy and stores it in the solar battery. At night, the battery supplies power to the LED light source to make it glow. Led solar street light can last longer than we expected if properly taken care of. Each of the component has its own lifespan. Solar street light integrate these components together. Let's go over these parts and find how long is the lifespan of the led solar street light? Everyone knows the solar panel, which is the power generation equipment of the whole light system. It is composed of silicon wafers and has a long lifespan, which can reach about 20 years. However, if you want to make solar panels reach the expected lifespan, you also need to pay attention to maintenance during use. The main function of solar panels is to convert solar light energy into electrical energy by absorbing solar energy, which is stored in rechargeable batteries. Therefore, the solar panel can not be shaded during use. If the top of the solar panel is blocked by trees, the trees need to be pruned regularly. Or if it is used for a long time, there is dust or snow on the solar panel after heavy snow, etc., it is necessary to clean the surface of the solar panel in time. If it is regularly maintained and the solar panels are used correctly, its lifespan can certainly reach 20 years. With the development of technology, led solar street lights are constantly upgraded. The new led solar street lights use LED light sources. The previous high-pressure sodium lamps and other light sources have serious light decay and have a short lifespan, while the light decay of LED lamps is only 3% a year. The LED light source is a low-energy-consuming product. Its power consumption is one-ninth of that of incandescent lamps and one-third of other lamps. It consumes very little energy, but has a long lifespan. The LED light source is composed of at least dozens of lamp beads containing LED chips, with a theoretical life of 50,000 hours, which is normally about 10 years. The key to affecting the lifespan of led solar street lights is the battery. Generally, the lifespan of lead-acid batteries is 2-4 years, and the lifespan of lithium iron phosphate batteries is 5-8 years. When buying a led solar street light, it is recommended to configure the battery to be larger. The lifespan of the battery is determined by its cycle discharge life. The cycle life of a lithium iron phosphate battery is more than 2000 times. Although expensive, it is easy to install, small in size, pollution-free, and has a long lifespan. The selection of battery capacity generally follows the following principles: First, on the premise of meeting night lighting, store the energy of solar cell components during the day as much as possible. At the same time, it must be able to store the electrical energy required for continuous rainy days and night lighting. The battery capacity is too small to meet the needs of night lighting. The battery capacity is too large. On the one hand, the battery is always in a state of power loss, which affects the battery lifespan and causes waste. The capacity of the battery is several times the daily discharge capacity, which can guarantee a longer number of consecutive cloudy and rainy days. The role of the solar controller is to control the solar panel to charge the battery and to supply and illuminate the led solar street lamp. A stable solar controller plays an important role in the lifespan of the battery. Generally, the controller has a high level of waterproof and sealing, and there is no problem for 6 years of normal use. As we mentioned above, quality of the components will affect the lifespan of led solar street light. Battery plays the most significant role in the street light system. Street light that adopt top grade materials can ensure the lifespan of 5 years. The led solar street light saves a lot of cost compared with conventional street lights. When purchasing the led solar street light, we should take all these factors into consideration. Be sure to find a reliable led solar street light manufacturer and check the warranty period of the solar street light.
