What Are All the Components Used in Solar Street Light and Their Working Principle
What Are All the Components Used in Solar Street Light and Their Working Principle
Solar street lights are the most functional outdoor lighting system that work automatically from dusk till dawn and use only green and renewable solar energy for their operation. The latest technologies have made solar street lights more practical, attainable and affordable. The main components of a solar street light are solar panel, light source, rechargeable battery, charge controller and interconnecting cables. The key role of a solar panel composed of multiple solar cells is to absorb solar energy and convert it into usable electricity to illuminate the solar street light. This process is called the photovoltaic effect. The performance of a solar street light majorly depends on the type and wattage of solar panels and the amount of electricity generated is determined by the size of the solar cells. Polycrystalline or monocrystalline solar panels are commonly used in solar street lights. The mounting position and the area of installation also can affect the panel efficiency. Solar panels have the best conversion rate when they are placed in such a way that sufficient direct sunlight strikes the panels throughout the day. Solar panels mostly have a lifespan of around 25 to 30 years. The main purpose of a battery in a solar street light system is to store the converted electric energy so that this power can be used at night to illuminate the light source. Modern solar street lights use either lithium ion or LiFePO4 batteries. Both these batteries are well known for their backup capacity and durability. The fact that lithium batteries are lightweight and compact makes them the perfect choice for solar street lights. Batteries with good storage capacity can help the solar street lights to continue lighting up even on rainy days when there is not enough sunlight to convert. Unlike lead acid batteries, lithium batteries do not demand any maintenance and knowing the type, total amperage hours and voltage of the battery can help you choose the right light. The converted electricity gets stored in the battery via the controller. A controller protects the battery from overcharging or undercharging. When the charging process comes to a halt at dusk, the controller prevents backflow of electricity from the battery through the solar cells. PWM and MPPT are the charge controllers commonly used in a solar street light unit. Controllers offer multistage charging and are able to convert excess voltage into amperage which extends the battery life. Understanding the type of charge controller used in your solar street light will help you understand their capabilities and functions better. The photoreceptors within the lamp sense when the conversion process stops and turn on the light using the electricity stored in the battery. LED is the most common light source used now as it consumes less energy compared to fluorescent and incandescent lamps. LED lights are becoming more and more popular in solar light applications as they do not burn out and emit zero ultraviolet rays. The LED technology helps the lamps to deliver much higher lumens using less energy. LED light fixtures are less prone to failures and offer around 50,000 working hours. They create a pollution-free ambiance and do not produce much heat in the form of infrared radiation. The luminosity per watt and the light distribution pattern of the LED need to be considered while purchasing your solar street light. The luminary is housed in durable ABS and aluminum alloy with IP65 waterproofing to sustain harsh weather conditions. The working principle of all in one and integrated solar street lights is the same; however, the working pattern of these lights is different. While some of the lights work with motions sensors, others have timer-based dimming options. The panels should be fixed separately if it is an integrated solar street light and the panel and the luminary are connected with the help of the cables given. Solar panels do not require separate installation as all the components are integrated together in all in one solar street lights.The Best Models of Solar Street Lights: Opinions, Features and PricesIn this article you can find Opinions, Features and Prices on the best models of Solar Street Lights currently on the market.

In contrast, solar street lights are safe, energy-saving, environmentally friendly, easy to install, and maintenance-free automatic control lights. It is composed of solar street lights: solar panels, solar batteries, smart controllers, light sources, lamps and brackets. The working principle of solar street lights:. The solar lamp uses solar panels to receive and convert solar radiation into electrical energy. The charge and discharge controller detects the action value during the day. The battery discharges the lamp. After 10 hours, the battery is discharged. The charge and discharge controller acts, and the battery discharge end. The main function of the charge and discharge controller is to control the opening and closing of the street lights, while protecting the battery and prolonging the service life of the battery. Solar street lamp design principle:. 1, the main function of the road lighting system is to ensure traffic safety, improve transportation efficiency, protect personal safety, and provide a comfortable environment. 2 To meet the needs of road lighting functions, improve the efficiency of road lighting systems, reduce system power consumption, save energy, and reduce pollution, so as to achieve the purpose of energy saving and environmental protection. 3, in addition to the local light resources, when the street lamp manufacturer's weather conditions, the battery panels are covered by dust, the temperature, the controller, and the actual conditions of the battery consider the battery efficiency. In the future, solar resources and wind energy resources will be widely used in various fields, not just the street lamp industry. Let green energy accompany us for a long time, and the use of wind-solar complementary street lamps has already let us know its advantages and can bring very considerable Social and environmental benefits. Wind-solar complementary lighting street lamp is not only low energy consumption, low-carbon, but more importantly, it can make our lives healthier. LED wind-solar complementary street lamp green daylighting lighting under natural lighting conditions has a higher visual contrast sensitivity than electric lighting by 5%-20% Above, everything is so clear under the bright sunshine. The light guide lighting system directly transmits natural light, full spectrum, no frequency display, no dazzling, making our environment more comfortable. Lighting is what we all need. Traditional lighting methods consume a lot of electricity. While obtaining electricity, they emit a lot of carbon dioxide, sulfur dioxide, nitrogen oxides and other harmful gases into the atmosphere. These gases cause various global environments. The street lamp manufacturer is an important reason for the problem, but the use of wind-solar hybrid street lamps completely avoids these problems. The characteristic of wind-solar complementary LED street light is to use sunlight to illuminate the solar panel and convert it into electric energy to charge the battery, or it can be used for power generation and lighting when the wind reaches level 3 or higher. When it is not enough, it will be charged by solar panels for lighting. The use of wind-solar complementary LED street lights has strong reliability, which is specifically reflected in that it can be used for three to five days without wind energy and solar charging, and LED wind-solar complementary street lamps can still perform normal lighting work and light control Lights on, time control to turn off lights, half power, full power automatic control, but generally speaking, there will be less wind and solar energy, so wind and solar hybrid solar street lights can fully achieve lighting. Wind-solar complementary LED street lights can be used continuously for more than ten days after a single storage of electricity. At the same time, two different types of light bulbs can be installed on the street lights and can be automatically adjusted and switched off according to light differences.What Parameters Should Be Paid Attention to when Purchasing Solar Street Lights?Different installation environments have different requirements for LED solar street lights, so the configuration of solar street lights is naturally different, such as outdoor lightings and road lightings, such as main roads and secondary roads, which are different. Then when installing outdoor solar street lights, what parameters are often involved? Let's take a look at it in detail below. That is the rated voltage of the battery. The voltage of a single solar cell is generally 0.40.7V. The common solar cell module is 36/54/60/72/96 in series, and the voltage is about 18/27/30/36/48 volts. This can be inquired directly online, select the best angle of the monthly average radiation, and the minimum three-month average value is required. When installing, you must also pay attention to the angle and direction of the installation to ensure that the automatic solar street light can accept sufficient sunshine to guarantee to charge efficiency. This is determined according to the local climatic conditions. The charging efficiency of the solar battery cover plate is naturally not as good as that of the sunny day on cloudy and rainy days, so it is necessary to ensure that the battery can store enough power to allow outdoor solar street lights to be used normally on cloudy and rainy days, which will also involve the work efficiency of the battery panel. That is the number of sunny days between two consecutive cloudy and rainy days. It should be noted here that when calculating the relevant parameters, the average sunshine is generally used as the basis for the supplementary charging on a sunny day. The actual radiation amount in a sunny day is greater than the average sunshine. And it's not that there is no battery charge into the battery during rainy days, so when calculating this parameter, you do not need to choose the interval between consecutive rainy days, you can enlarge the value appropriately, the value of the interval between rainy days and rainy days. A ratio of 1:3 or 1:4 is more appropriate. A solar panel is generally composed of multiple solar cells connected in series, and its capacity depends on the total power consumed by the lighting source, line transmission components, and local solar radiation energy. Under normal circumstances, the output power of solar panels should be more than 3 to 5 times the power of the light source, 3 to 4 times or more in areas with abundant sunlight and short light-on time. The area where the lights are on for a long time due to poor light conditions needs to be 4 to 5 times or more.

Further, the head of solar street light also comprises a reflection plate which is equipped with plural cylindrical lamp tubes. The LED light set is arranged between the reflection plate and the reflection cup, and each LED lamp bead of the LED light set is arranged in the corresponding cylindrical lamp tube.Tips Linked To Solar Street Light Manufacturer SelectionWith the pressure on to conserve energy, many companies and local authorities are installing solar powered street lights. These lights not only help save money, but also help reduce the pressure on power generation plants thus helping reduce greenhouse emission production. It also helps reduce pressure on the power grid thus helping divert the energy to other sectors and industries which need it more. When planning to purchase a large number of solar street lights, it's important to keep certain factors in mind so as to select the right solar street light manufacturer and brands. Below are some of these factors which will help make more informed decisions: Street lights are meant to light up large areas thus requiring the solar lights to be bright. It's important the radius each light eliminates be taken in to consideration thus allowing the distance between lights to be calculated. This makes it possible to determine the number of solar street lights that are required and helps estimate the cost. The larger the radius covered by each light, the fewer the number of solar street lights you need, thus helping reduce solar street light purchase and installation costs. It's important to keep in mind that street lights are a public utility and therefor tend to be mishandled. This makes it important to select solar street light which is made using strong materials which will prolong the usable life. Keep in mind that the lights tend to be an insect attraction and require to be completely sealed to prevent insects and other animals seeking shelter inside the lights. It's common to find small animals like rats and squirrels finding their way in to street lights and making themselves at home since the lights provides a source of warmth during the cold winter nights. Also make sure the lights are strong enough to support extra weight. This is because you are bound to find birds perching on the solar street lights which can result in breaking of the lights. The materials used to make the lights also require being corrosion resistant to prevent deterioration over short periods of time. Today, there are several alloys and plastic materials which can be used on the lights to help prevent corrosion. On some parts of the light anti-corrosive materials can be used to coat the metals and prevent any damage from heat and water. It's also important to take the wiring in to consideration to help reduce the maintenance requirements. Today NANO technology has resulted in miniaturizing most electronics including solar street light controls. This means that they have all the required components inside the street light. They have an in-built solar charging unit, battery cells and an automatic light sensor which turn the solar light on and off.

Smart Solar Street Lights are targeted towards the poor and low-income communities. They come with solar charging technology to allow them to stay on for days when they are not charged by the sun. The color of the lights can be customized according to the users' desire.Solar Street Light Information-how To Choose The Best Solar Led LightsHow to Choose the Best Solar LED Lights for Your Garden So you want to buy lamps for your garden! Perhaps, you wish to highlight the elements of your garden. Maybe, you want to add ambiance to your outdoor space. No matter the reason, buying outdoor lamps can be an expensive proposition. Your budget could be hurt if you have a bigger garden. So how can you resolve this issue? The best answer would be a solar LED light for the garden. However, buying the right lighting can be a task. If you do not know how to choose the best garden solar LED light, here are handy tips that should help out. Tips to get the best solar LED lights In recent years, solar LED lighting technology has improved to a great extent. This is why many folks are switching from mains powered lamps to solar lighting. However, when you decide to go after this innovative option, you may want to take into account the following important things. So you've to take into account the type of bulb you need. Most of the solar-powered lamps use LED technology to generate light. These bulbs are extremely effective as they emit enough light and generate less heat compared to other bulbs in the market. That also means they will last longer with less battery charge. Since solar energy is stored in a limited quantity, such bulbs are highly recommended. Plus, energy-efficient garden solar LED light wo not lose energy like other outdoor lamps. As such, you can be sure that your landscape will stay illuminated for a long time period. No matter how efficient solar lights are, they will illuminate the space as long as they are charged. Once the charge is used up for illumination, the light wo not turn on. You ought to have the lamps charged all the time or at least for a longer time. So how can you do that? Removable lithium-ion batteries would be the best answer to this question. They are easy to replace. Also, they can be charged with the mains power in case the power of your solar panels gets exhausted. Additionally, removable batteries are easy to maintain. If a solar lamp is under-performing, the main culprit is the battery. In such a situation, you can take out the batteries and charge them for optimum performance. If the batteries are spoiled, you can replace them with the new ones. Such batteries are really beneficial during cold and wet seasons when there's little to no sunlight for sustaining the energy needs of your lamps. Another important point worth noting is to charge the batteries fully before putting them in the bulbs. In addition to this, make sure to have a duplicate set of batteries. That will ensure uninterrupted lighting supply from your garden solar LED light. When one set of batteries is in use on the bulb, the other set is getting charged Some solar LED lights have just one setting - a manual on/off switch. However, certain lights are more versatile and come with an automatic on/off switch. The switch turns on the bulbs in the evening and turns off when the sun rises. It's better to consider an automatic switch because you do not need to worry about forgetting to switch off the light in the morning, which could drain out the battery. Another important feature to consider is the dimming setting of the solar LED light for the garden. Certain bulbs have the dimming setting which allows you to decide the amount and level of brightness you want according to your needs and battery status (the charge in the battery). When you are choosing solar lighting for your landscape, you may want to consider powerful, efficient photovoltaic cells. These cells convert the light energy from the sun into electrical energy, which actually charges the batteries of your bulbs. Powerful cells are capable of converting more light energy into electrical energy, thus giving you more charge for the batteries. In the end, you have a better performing bulb, which means you have a brighter light for a long time. Different solar lights are available for lighting different areas of your garden. For example, accent lights produce an ambient light that lit up a smaller area. Such bulbs essentially highlight particular elements of a garden. For instance, accent lights can throw light on flowers in your garden to give better visuals at night. On the flip side, landscape lighting presents a spotlight for highlighting a larger feature of your lawn. These bulbs might be set along a tree to light it from various angles during the night. It's advised to choose LED lights depending on the functions you want them to do. A set of accent and landscape lights will make a perfect blend to ensure functionality all over the landscape. Of course, you want to add an element of style to your garden with lighting. So do not forget to match the new lighting with the style of your lovely landscape. Go for designs and colors that line up with the atmosphere of your beautiful lawn. Bulbs by themselves are fragile. In spite of this, some models are better than others. You want to buy lamps that will serve you for a longer time frame without wearing out. So do not forget to check the longevity of the bulbs in question. You can scan reviews and ratings of the bulbs to ascertain their longevity. Obviously, you do not intend to shell out too much money on solar LED lighting. So make sure you check the price of the bulbs. While you may wish to have low-priced lamps, do not go after cheaper models. Rather, try to have the right balance between quality and pricing. Explore good-quality bulbs that come with an affordable price tag. Buying solar lights for your lovely landscape is not an issue. However, picking the best garden solar LED light takes time and efforts. Yet, your efforts will be rewarding in terms of low cost, low maintenance, eco-friendly lighting, and a lot besides.

These projects offer colleges and universities a number of ancillary benefits beyond the obvious goal of reducing carbon emissions, and often save money in the long run as well. Chief among these benefits is reducing the cost of energy. Additionally, since lighting costs often make up a large portion of a university's energy spend, renewable lighting solutions should be explored. With extensive grounds and numerous buildings to illuminate, the lighting bills can add up quickly. Solar panel technologies have made it possible for campuses to significantly decrease lighting installation costs and eliminate the electricity bills associated with outdoor lighting. The economic appeal of solar lighting will only increase as the prices of solar modules, batteries and LED lighting continue to decline. LED technology has become extremely efficient and has a long product life when compared with traditional types of lighting such as sodium vapor and fluorescent lighting, therefore significantly decreasing operations and maintenance costs, while continuing to deliver a bright, crisp white light that does not fade in intensity. Solar-powered lights also provide high quality light for more than five days without a single ray of light due to advancements in battery technology. Solar lighting is a public demonstration of an iuniversity's commitment to a "green" orientation, allowing a university to project an environmentally conscious message throughout the campus When Odessa College in Odessa, Texas, an 80-acre campus with more than 11,000 students, chose to install solar lighting instead of traditional grid-tied lights, the university executive team's main concern was with the safety of students and staff walking to and from classes across a sprawling campus. In particular, students felt unsafe in the parking lots and on their walks to campus, prompting the search for a cost-effective solution. However, the existing buildings and landscape also played a large role in the ultimate decision to go solar as the installation of grid-tied lighting would have required prohibitively expensive trenching and wiring. Since solar outdoor lighting does not require a connection to the electrical grid, the advantages of solar lights were immediately apparent. Additionally, the money saved was a pleasant upside that will continue for years to come. Odessa was able to save around 20 percent of the cost of a new system at the time of installation due to the avoidance of the wiring and trenching needed for traditional grid-tied lights. Because the systems are 100 percent solar powered, the lack of electricity bills is saving the university more than $8,000 per year, without even taking into consideration the savings on operations and maintenance costs. In addition, EnGoPlanet Solar street light has many useful features that students, professors and guests of university or school can use, such as USB charging ports, Wireless Charging, bench. The conlusion is that reliability that EnGoPlanet Solar street light offer really help students feel safe at all times in and around their campus.For Solar Street light, How to calculate the rating for LEDs used, battery and the solar module itself?It's a difficult thing to calculate. You need: worse case number of hours of full sun per day Number of hours the batteries have to run the lights on days without sun. The problem is, you can have perhaps 3 days without sun due to a storm. that means the batteries have to power the light for that number of hours. And then when you get, say, 6 hours of sun, the solar panels have to be powerful enough to recharge that bank of batteries in that time. So, you have to set all of these parameters, else you wind up with several hundreds of watts of solar panel for a 40 watt light and a huge battery. Take an example. An ordinary auto battery can store about 1 kW-hour of energy. To operate the 40 watt light for 70 hours, means you need a 2800 kW-hour of storage, or 3 auto batteries. To recharge that 2800 kW-hours in 6 hours, you need 500 watts of solar panel. And that does not count losses. .

1. Use the right words for the task: If a software company needs to generate content for its clients, it must use the appropriate keywords in their content marketing strategy.2. Make sure you have the right amount of text and images: Although this is great advice, a few examples can help illustrate how important this is: Two different slogans on a business card would be very different and it's impossible to make them both look good. In fact, they could even be so different that they don't even represent each other.3. Create copy that appeals to your target audience: A good way to ensure you get your point across is by creating copy that will appeal to those who are most likely to buy your product or service. This could be through aesthetics or by appealing to emotions such as fear orHow to Ensure Waterproof Function of Led Solar Street LightLED solar street lights are being installed in more and more countries. They are favored by people due to the energy-saving and green advantages. They are exposed to the outdoor environment all year round, wind and rain, and even face the attack of thunder and typhoons. So how do solar street light manufacturers use technology to make LED solar street lights waterproof? The waterproof of LED solar street lights is divided into two parts, one is the waterproof of the controller, and the other is the waterproof of the LED street lamp head. The waterproof of the controller is particularly important, because the controller is the core part of the led solar street light. During the day, the controller converts solar energy into electrical energy, and at night the battery provides electrical energy to the street lamps. The waterproof of the controller means that the circuit board of the led solar street light is treated with a tri-proof insulating paint during installation, so that rainwater will flow away along the edge of the controller. During construction, attention should also be paid to bending and fixing the internal connecting wires of the controller terminals into a "U" shape. The connecting wires exposed to the outside are also fixed to a "U" shape, so that rainwater cannot enter and cause the controller to short-circuit. In addition, waterproof glue can be applied to the inner and outer line interfaces to waterproof. If waterproofing is done well, the service life of led solar street lights can reach 10 years. If the waterproofing is not done well, generally after 3 years of use, the controller will have a short circuit. Therefore, the waterproofing of the led solar street light controller will directly affect the service life of the led solar street light. The waterproof of LED street lamp head is also very important. Only by doing a good job of waterproofing the lamp head can the stability and safety of the LED street lamp lighting at night be guaranteed. The exterior design of the LED solar street light housing should not be concave, try to choose the online through-hole style, which is conducive to the rapid evaporation of water from the LED solar street light housing. LED solar street light chips and lenses must consider their waterproof performance and reach IP66 level ( only for high performance solar led street lamp). The back cover of the street lamp head, the back cover of the power supply box, and the threading hole in the power supply box are respectively made of waterproof rubber strips and waterproof plugs with good sealing performance. It is necessary to do a good job in the aging detection of LED solar street light caps. The waterproof rubber strip at the internal joint of the LED street lamp has a service life, and the sealing performance of the joint may decrease after a few years. The above are some ways to do a good job of waterproofing LED solar street lights. Of course, when you purchase LED solar street lights, do not choose products produced by small workshops. First, because the small workshops have less production equipment and poor craftsmanship, most of the LED street lights waterproof work is not good, and you must do it from a reliable LED solar street light manufacturer. Solar light price is not the only point that you should focus on.
