The New Countryside of the Road and Street Lamp Project Has Been Replaced with Solar Street Lamps
The New Countryside of the Road and Street Lamp Project Has Been Replaced with Solar Street Lamps
With the vigorous promotion of the new countryside, solar street lamps have been replaced on the rural roads. According to the road lights, it has brought many conveniences to the people's daily life.However, with the extension of time, some solar street lamps have not been lit after two or three years of application. As a technical professional solar street lamp manufacturer, let's share the key reasons and maintenance methods:1. Components likely to fail:(1) Lighting fixtures, led bead problem, welding line problem(2) Battery, charging battery embrittlement problem, resulting in non charging and non discharging of the battery(3) Solar power generation controller,2. Solution:(1) First check whether the wiring terminal blocks of lighting lamps are loose.(2) Use a multimeter to measure the working voltage of the battery. If it is less than 11V, it indicates that the controller is in maintenance. The lamp can be applied after it is fully charged. If it is higher than 11V, it indicates that the controller is faulty and needs to be replaced.(3) Remove the LED light source, check whether the lamp is working normally after receiving the battery or DC12V power supply, and pay attention to the positive and negative. If the lamp is not on, it indicates that the LED lamp is faulty. It is necessary to remove and replace the LED lamp. If the lamp is on, it indicates that the controller or battery is faulty.To sum up, the solar street lamp maintenance must be carried out by a technically professional solar street lamp manufacturer. If you don't understand, it's not recommended to replace spare parts indiscriminately. Call the technically professional solar street lamp manufacturer, and you will help you solve your difficulties at the first time.
Solar Lights Aren't Working When My Electrical Lights Are On!!!?
The solar lights have a photocell which turns them off during the daylight so the battery will charge. When the photocell detects the electric lights it thinks it's daylight and shuts down. The photocell must be located somewhere other then on the panel.1. Can you replace the solar panels and charger in a solar system with a car alternator D/C electric motor?Not sure why you would want to do this. But if you were to replace it, how would you power the D/C electric motor? The whole idea is to charge the batteries (if you opt for a battery based system), using the free source of energy, which is sunlight. You can use all sort sof gimmicks and hacks in between, but the end result has to be looked at matching the voltages/currents and efficiency (you want to have minimal loss in your system).Can you replace the solar panels and charger in a solar system with a car alternator D/C electric motor?Can you replace the solar panels and charger in a solar system, with a car alternator D/C electric motor?.2. Does our solar system have a name?Q: Does our solar system have a name? Does our moon have a name? Does our sun have a name? A: No. No. No. Sorry. They should. But they do not . At least not in English. There are, of course, many words used to refer to the Sun and the Moon in other languages. "Sol" and "Luna" are often thought of as proper names but they are really Latin, not English. So far there has not been a need for anything more. Maybe when we start living on other places besides the Earth....3. Solar panels to heat pool?well one 15 foot Panel will heat up to 10,000 gallons so i would imagine 7 of them depending on there size also it helps if you put them on your roof. also there is natural gas and propane heaters that work as good and that not that expensive to run as long as you keep the solar cover on it over night i have one too they are really easy to install then solar panels4. Modeling incoming solar radiationI studied physics in the old days but then had a career in engineering. I think it important to have experimental data to correlate with formulae and hypothesis. Perhaps astronomers studying solar radiation have data over several frequency ranges, times of year, latitudes etc. I think also interesting to know the amount of polarisation of the radiation according to the distance traversed, and its angle, through the atmosphere. IR reflective mirrors could redirect incident radiation vertically so that it would be lost to space with a minimum absorption and reflection by the atmosphere5. How do solar FARMS convert solar energy into electrical energy?There are several ways to use the sun's power to generate electricity. One of the most promising is called concentrating solar power. This involves using mirrors to reflect and focus the sun's rays, providing heat, which in turn helps power a generator. Another is photovoltaic panels, such as the displays on the rooftops of homes and office buildings6. How much power is consumed by a illuminating switch light in the off position? I wired a off-grid solar cabin.?Do not have an exact number, I would guess at 20mA at 60 volts (half wave to drive a LED) or about 1 watt. I would use non-lighted switches, unless you already have them installed. .7. anyone have a solar home?Things have changed a bit since Chuck did his study, but for most installations photovoltaic solar has a very slow payback. For example, my system cost about $50,000 six years ago. It generates an average of about 20 kWh per day. At 12.6 cents per KWh, it saves me about $75 per month. It does a bit more for me, though. I live alone and am able to put up with heating just one room in the house, with electric heaters. If I did not have the solar system, I would have to heat with gas, and could not heat just the one room. Gas prices have skyrocketed, so I would have that additional expense. I am considering installing a geothermal heat pump system so when I sell the house in a few years it will look very attractive to prospective buyers. The combination of PV and the heat pump should bring down the utility bills to a very low figure.

Public space lighting (PSL) is an important component of the urban environment and has a major contribution to the pedestrians' overall feeling of safety (FoS) and comfort after natural dark -. Effectively, PSL is characterized by several attributes-illuminance, light color temperature, uniformity and glare ,-each of which may influence FoS, as well as energy consumption -, and human health , . PSL is currently designed according to international, national or local standards, such as EN 13201 . However, since the association between the above-mentioned lighting attributes and pedestrians' FoS has not been sufficiently studied , , it is not clear enough how well do the abovementioned standards, albeit technically efficient, contribute to FoS. Moreover, human perceptions of PSL attributes may be influenced by socio-demographic characteristics and may vary according to individual, locational, environmental and temporal circumstances. Therefore, an empirical model that links lighting attributes to FoS and considers various contextual factors is currently lacking. The present study attempts to fill this knowledge gap by developing a PSL-FoS model that links illumination, light color temperature, uniformity and glare values with FoS, while controlling for individual, locational, environmental and temporal factors. Such a model may help to adapt PSL to various settings affecting FoS, and thus may contribute to increased urban residents' satisfaction and wellbeing, while reducing health and ecological risks, and increasing energy efficiency. Several studies have looked into the factors affecting the perceived quality of nighttime illumination by pedestrians , 13-. However, most of these studies were performed in laboratory conditions, which cannot realistically reflect the complexity of outdoor environmental factors (e.g., time, weather, vegetation density and terrain), thus potentially causing biases in the information collected. Studies focusing on outdoor lighting constitute a distinct strand of research , 12, 25, , but they are relatively scarce and entail various limitations. Most of these studies are based on "self-report" questionnaires, which are subjects to various biases and limitations, such as inefficient management of information on measurement time and location during the assessments . Using "paper & pencil" technique to record PSL assessments outdoor after-dark may also pose difficulties, especially to the elderly and visually impaired . Consequently, some respondents may prefer to record their assessments later on, in better visual conditions, which may introduce uncontrolled errors, resulting from memory limitations . Another bias may occur due to insufficient guidance to find the exact location of the designated assessment points. A significant bias may also result from having company during the assessment, such as in the studies of Kelly et al. and Wu , where observers were sent to perform FoS assessments in couples or accompanied by research assistants. In a recent study, Fotios & Johansson examined how pedestrians appraise others' intentions in different outdoor settings. The researchers conclude that as long as a person can identify other pedestrians' faces, PSL is sufficient. Furthermore, the study in question was performed in a simulated built environment, and involved a relatively small number of subjects, which limits its generality. To sum up, we should remark that previous studies that explored potential associations between artificial lighting and FoS have had several limitations. First and foremost, most of such studies were carried out in laboratory conditions . Second, most of them used "paper & pencil" self-administered questionnaires, which entail well-known drawbacks, such as inefficient management of important information in a timely manner . Third, most previous studies were based on a relatively small number of participants , which substantially limits their generality. Finally, none of the studies carried out to date attempted to link different PSL attributes (especially light color temperature) with FoS, while controlling for individual, locational, environmental and temporal factors. The study, which results are described in the rest of this paper, attempts to address these limitations by exploring how the abovementioned PSL attributes-illumination, light color temperature, uniformity and glare-affect pedestrians' FoS in different contextual settings. The multivariate analysis of the recorded data revealed several important findings. First, it was found that locational, socio-demographic, temporal and environmental factors have a significant effect on FoS. Therefore, universal lighting standards cannot be suitable to maintain the desired FoS in all urban areas. The analysis also shows that the minimal levels of illumination required for achieving the same level of FoS differ across cities, being higher in the inland arid city of Beersheba in compare to the coastal cities of Haifa and Tel Aviv-Yafo. This finding reconfirms results reported by Svechkina et al , which showed that residents of coastal areas, with often clouded skies and denser vegetation, may be satisfied with lower illumination intensity, in compare to residents of inland arid areas, characterized by stronger daytime lights and less light-obscuring vegetation. Another interesting result stemming from the analysis is that lights perceived as warm tend to generate a better FoS than colder lights, given the same level of illumination. This finding may guide future illumination polices aimed at reducing unnecessary energy waste and preserving a cleaner urban environment. Generally, our findings are in line with the results of Rahm , who demonstrates that PSL, along with individual and environmental factors, have a significant impact on pedestrians' FoS. Nevertheless, the results of the current study are novel in several respects. First and foremost, improving pedestrians' FoS can be reached either by switching the light color temperature from cold to warm, or, alternatively, by increasing illumination. The former approach is less energy consuming and may result in substantial economic and environmental benefits. Second, locational factors (such as different cities and neighborhoods), as well as temporal factors (such as hour of the evening and month of the measurements), which were not assessed in previous studies, were found in the present study to have a statistically significant effect on FoS. It is important to note that in this study, the predicted FoS was linked to assessed PSL attributes, while, alternatively, the level of FoS could potentially be linked to instrumental measurements. Although both approaches-that is, individual assessments vs. instrumental measurements of PSL attributes-have their own merits, in the present study, we preferred to use the former assessment type. Our main reasoning is that people effectively link FoS to their assessment of lighting attributes, not to instrumental measurements, which they are unable to perform. Lastly, we note that this study uses the standard ordered logistic model, which, at least in theory, may lead to erroneous conclusions that some explanatory variables are less significant than they actually are (false negative conclusions). However, since we have found significant effects, the issue is not major and the identified significance levels we have found may be viewed as a lower bound of the true significance. Future studies may consider the use of generalized ordered logistic models -, to reduce this concern. An explanatory model linking FoS with different PSL attributes, along with controlling for individual, locational, environmental and temporal factors, is estimated and reported in this study. To estimate this model, 380 observers were asked to assess PSL attributes in different urban settings during different hours of the evening, as well as to evaluate their perception of FoS associated herewith. For this purpose, a specially designed cellular phone application, CityLightsTM, which represents a novel interactive real-time methodological approach, was designed and employed. This app provides an efficient alternative to the "paper & pencil" questionnaires, commonly used to record observations made during an outdoor experience. Based on cloud technology and GPS, the app enables pre-authorized observers to record their assessments along with temporal and geographic information, while preventing observers from deviating too far from pre-determined reporting points. The app also prevents the same observer to enter the same assessment point more than once, and blocks the use of the app before the natural dark or by unauthorized people. In this manner, the app ensures the accuracy and integrity of assessments. The present study is the second in a series of planned studies, carried as part of a large-scale research project, funded by the Israel Science Foundation. The project aims to model the perceived quality of PSL in urban areas by using an interactive user-oriented approach. The first paper in this sequence aimed to identify only the level of illumination required by pedestrians to feel safe while walking through the streets at night. Concurrently, the present study links different PSL attributes (illumination, light color temperature, uniformity and glare) to FoS, while controlling for individual, locational, environmental and temporal factors. The study was carried out in three large cities in Israel-Tel Aviv-Yafo, Haifa and Beersheba,-along pre-defined routes in 10 different neighborhoods (three-to-four neighborhoods in each city). A representative sample of participants used the CityLightsTM app to report their assessments from 257 pre-designated points, yielding altogether 25,940 individual valid records, which account for different PSL attributes. The results of this study hold a potential for improving pedestrians' FoS through better design of PSL by soliciting interactive responses from local residents and adjusting PSL attributes to their needs. Such a user-oriented approach allows to receive real-time feedback and may thus elevate PSL systems to a new level of interactivity and intelligence. Findings of the study may also guide future PSL polices aiming at increasing energy efficiency and reducing health risks to humans and ecosystems. This goal can be achieved by adjusting not only illumination intensity, but also light color temperature, to the desired levels of FoS, concomitant with desired goals. By venue of this, the results presented in this paper can be of interest for urban planners, environmental law enforcement authorities and decision-makers in local municipalities. In particular, following the results presented in this paper, PSL design for desired FoS can enable temporal and locational variations of illumination intensity and light color temperature and their locational variation, to reflect population makeup and building patterns in different neighborhoods and in different cities, thus helping to achieve a desired level of FoS. In particular, study results may encourage PSL designers to use warmer light, which can generate higher FoS for the same level of illumination. Applying just this strategy may decrease PSL-associated costs, in compare to those generated by the commonly used cold lights. Furthermore, as warmer lights are associated with higher FoS, using such lights may compensate for a reasonable reduction in required illuminance, without compromising FoS. The model estimated and reported in this paper can help to estimate this possible tradeoff between required illumination level and light color temperature for any desired level of FoS. The study findings may guide decision-makers towards improving new urban design and street retrofit projects. For instance, according to our findings, to achieve acceptable FoS levels, street lighting (SL) designers should focus on three main factors-illuminance, uniformity and light color temperature. In doing so, SL designers should keep in mind that, according to the study findings, urban residents appear to prefer warmer lights, which make them feel safer, in compare to cooler (i.e., bluer) lights. It is also important to keep in mind, that illumination levels should reflect contextual settings, considering that residents of cities, in which daytime radiance levels are high, may require more nighttime illumination to feel sufficiently safe after natural dark. As the results of the present study also indicates, in designing PSL installations, planners should account for the demographics of potential users, such as age and gender, which were found in this study, along with the environmental characteristics of different urban settings, which appear to significantly affect FoS perceptions. Temporal factors should also be taken into account. For instance, PSL level should be designed to enable increased intensity in illumination or changing light color temperature towards warm after 22:00, in order to maintain the same level of FoS. Thus, the study may contribute to optimizing PSL standards, which are presently mostly geared towards road traffic rather than to pedestrians' needs. Several interesting topics, which were beyond the scope of the present article, can be addressed in future studies. Two of them hold promising potential to quantify energy savings: the relation between FoS assessments and PSL instrumental measurements, and the potential linkage between illumination intensity and color temperature. Future studies may also increase the FoS-PSL model's validity and credibility by using means, such as a larger number of observers in each neighborhood, additional neighborhoods in each city, additional cities, more diverse urban settings, and various socio-demographic and cultural conditions. Another important future direction for scholarly enquiry is interactions between different FoS predictors, such as e.g., age and gender, and their combined effects of FoS.

First Uk Aid Dropped in Iraq for Yazidis Who Fled Is Militants
A British military aircraft has made the first drop of UK aid in Iraq. The Ministry of Defence said the plane had carried out its mission overnight. The focus of the aid effort is on helping thousands of members of the Yazidi religious minority, who are trapped on a mountain in northern Iraq after fleeing from Islamist militants. Downing Street said the humanitarian situation in Iraq remained "deeply worrying" and said it planned to step up aid drops in the coming days.Parallel to the aid effort, US planes have been carrying out air strikes against the militants.The US military said it had destroyed vehicles and equipment of the Islamic State (IS), which has been attacking Yazidi areas. The militant Islamist group, formerly known as Isis or Isil, has seized swathes of territory across Iraq and Syria in the past few months and has threatened Iraqi minority groups. Two British C130 cargo planes are delivering the aid to those who have fled from IS's advance. Defence officials said one plane had dropped supplies that included reusable water filtration containers, tents and solar lights that doubled as mobile phone chargers. International Development Secretary Justine Greening said: "The world has been shocked by the plight of the Yazidi community. They face appalling conditions, cut off on Mount Sinjar after fleeing persecution."The UK has acted swiftly to get life-saving help to those affected."The US, France and the UN are also taking part in the international aid effort.Estimates for the number of people trapped on Mount Sinjar range from 50,000 to 150,000. The UK aid contribution for those displaced in Iraq is worth £13m in total. It includes: Foreign Secretary Philip Hammond has said the aid effort is likely to continue "for the foreseeable future" until a way is found to get those sheltering on Mount Sinjar to safety. The government says any long-term solution must involve the formation of a more inclusive Iraqi government, uniting all the country's ethnic and religious groups.Who are the Yazidis?
Efficient Solar Garden Lights for Homeowners
Gardens are usually the first location visitors appear at when they enter your gate or drive by your house. A huge majority of the population invests significant amounts of precious time and energy making sure their garden is in tip leading shape. The problem is although that unless the garden is nicely lit no one can completely appreciate it when it really is nighttime. Most homeowners do not comprehend that their gardens might be greatest displayed and appreciated throughout the night. The remedy to this problem is easy. Install solar powered garden lights so you'll be able to see your garden both day and night.SensorsAmong the greatest rewards of solar lighting today is sensors. Most outdoor solar garden lights on the market nowadays have sensors to detect the dusk as well as the dawn. The sensors turn the lights off through the daytime and turn on automatically inside the night. Solar Lights once installed are self effective. Even in the midst of a power outage the lights will continue to function.SecurityAnother benefit of solar power garden lights is the security they provide. By illuminating your property it'll not just appear far better but deter criminal activity. Low lit areas have verified time and once more to be hotspots for criminals to conceal themselves from sight. Foundation plantings, shrubs, and densely wooded locations of one's yard are frequent hiding spots for would-be burglars. Crime statistics show that if burglars are at danger of getting noticed in a bright light, they are not most likely to hide anyplace in the location.InstallationInstallation no longer requires an professional technician, and you'll find no far more high electrical bills with lights burning all night. A commonly wired light fixture would require someone to come set it up, run the wires after which ground them properly. With solar lighting, all that's necessary to set it up would be to place the light fixtures where you need them. These will likely be either mounted on a pole or wall or they could be basically staked into the ground. The video I have added below shows you just how easy it really is to install solar garden lights.Prevent Theft1 question I get asked frequently is how you can stop solar garden lights from finding stolen. I've heard many various ways from pouring cement to installing security cameras. The cheapest and ideal suggestions that I have received is to do as follows. Drill a hole by way of the base of each and every light. You want the hole to be just beneath ground level. Subsequent string a plastic jacketed steel cable although all of them. Lastly, dig a shallow trench between the lights to location the cable. I've by no means had or heard of any lights being stolen with this strategy.LED TechnologiesOne of the principal concerns that I hear is that solar lights are dimmer than regular lights. This may have been the case years ago but new LED (Led Emmiting Diodes) technology has changed this belief. Depending on the model some solar lights are just as bright as conventional lights. One more thing to consider is the fact that LED's lasts longer than conventional lights since there is certainly no filament in them and they don't waste power by giving off heat. Most of these lights have many LED's and have a reflector inside to give off maximum light which is distributed evenly.LED solar lights are potent sufficient to supply fantastic lighting for your garden.Shopping for Solar Garden LightsIn one way or another, we all desire to save some funds. Why not start off using the solar garden lights? They'll save cash on the energy consumption, are environmentally friendly, and won't call for pricey installation or perhaps a technician to work on maintenance fees. There are a wide range of solar lights to select from depending on what you are trying to find. Some of these components incorporate the layout of your garden, its size and also the impact which you want produced. With so many alternatives here are some web sites which have the top alternatives for you.For more information on solar lights visit outdoorlightingnow.com

When the base voltage is greater than the emitter voltage, the current (Ic) flows into the base. Assuming the current gain to be B, the current flowing into the collector is B(Ib).Mathematically, Ic=B*Ib.Ohm's law says V=IR. So the resistor must drop the voltage. How much voltage does it drop? Here, the transistor is supposed to work on saturation region. Meaning the collector-emitter voltage (Vce) is lowest possible. So almost all (but not all) voltage is dropped across the resistor. What you are left with is very little voltage at collector. And this is where the output is taken from. Lets look at next scenario. If there was no resistor between the collector and the Vcc, the voltage drop must be provided by the transistor. You have Vcc at the collector and 0V at emitter. The transistor must drop all the voltage. Your output would always be high no matter what you provide at the input.simulate this circuit - Schematic created using CircuitLabDo we need CFD for GATE exams?No, CFD is not in the syllabus for GATE Aerospace-2017.GATE is mainly for assessing your basic engineering knowledge.
