Solar street light design Microcontroller-based intelligent control system
Smart Solar Street light is the use of solar photovoltaic effect component, the light energy into electrical energy and stored in batteries for load use, it is a solar photovoltaic technology, battery technology, lighting technology in one of the emerging technologies. Solar street light controller is used in solar photovoltaic systems, coordination of solar panels, batteries, loads of work, so that the whole solar system is efficient and safe operation.
An intelligent solar street lighting system overall program
Intelligent solar street light system from the solar panels, batteries, LED light (main light, Vice-lamp) and a controller (Figure 1). Solar panels during the day and the sun's radiant energy into electrical energy output, after the charge control circuit is stored in batteries; evening when the light intensity decreases, the deputy controller lights, the direction of illumination. When the controller detects when the controller while it was lit after the main light and vice-lights, the lights around the same time and adjacent communication, control lights adjacent to the main light and lamp lit at the same deputy, to ensure that pedestrians in the road lighting. Controller to detect the battery charge or discharge beyond a certain range, the controller cut off the charge and discharge circuit to ensure the battery is not damaged. Encounter consecutive days of rain season can be switched to mains lighting, to avoid long-term battery power loss.

Brightness and illumination of LED street lights are contradictory
A live audience on "LED lights Design Brightness And Illumination Standard contradictions "and other standard items Advisory Leader International OLED, LED backlight, the light of international standards for radiation safety members of the Group, Information Engineering, Zhejiang University, Associate Professor Mou optical light with the rise; Tsinghua University, Shenzhen Graduate School, Professional Physical Electronics and Laser Devices, Research Associate; Graduate School at Shenzhen, Tsinghua University, deputy director of semiconductor lighting lab money to dollars
Question: I would like to ask the teacher have the money Mou teachers, we know there is a street light above the brightness of the design standards and illumination standards, how should we consider in the design of the above problem? If I achieve uniform illumination, then, may I also see the road will see bright spots.
Mou with l: I just talked about street illumination and brightness from the human eye's visual requirements should be based on brightness, but a new problem is now playing a large beam, now under illumination, we play at the following time , light we see are certainly below the shadow, this is bad for the driver. We all know his car, cement road, we are very far away, there is light in the past, is watery, not water, we looked brighter, which is a contradiction, according to my personal view, the brightness is more science. Of course, these two certainly contradictory.
Money to yuan: Mu teacher just put a lot of brightness and illumination on the street is a contradiction in things not diffuse lights, the second on to the next sixty meters, can not do if it is raining immortal solar power brightness uniform, rain water is the mirror, the driver is concerned is a point, can not always uniform brightness. Good concrete road, who did the lights go up according to very good, according to which points up the very good. Shenzhen dozens of Solar LED street light hung very good road, at night you will feel very uniform, but we do street we know that some asphalt put something hard to get, you feel very uniform, a distance that is zebra, brightness reflection of the relationship and the road too, even the best road the rain can not. Design of the road time to consider this issue, do not let the zebra so obvious. Speech talked about the brightness of the rectangle, not a photo down is rectangular, it is a problem, how to cover the type of light, brightness evenly, of course, your point is a good illumination uniformity thing. Finally, consider what would happen this way is good, our standards do not dare to write this thing, so it is passed. Uniform rate is not 100% is the best, it may take into account both, I think this put a very deep, may also encounter LED street light to do this problem for solar.

For two years in Guangzhou to establish 150,000 rural solar street lights
According to reports, September 1, Guangzhou Municipal Construction Commission will send three teams to the Design Institute of Guangzhou, about 90 villages to proceed with the installation of solar street light design.
"Rural street construction" is in Guangzhou City, the "Top Ten livelihood projects," one of the plans to be completed within two years, Guangzhou 150 000 in rural areas of solar street lights. The project is funded by the entrepreneurs, charities and funding subsidies. Guangzhou Construction Committee official said, 15 companies donated at least 2000 solar street lights, 25 villages will benefit.
Shenzhen to Guangzhou's Sun Fuyuan Technology, Taiping Town, Cong Hua City, Lam donated silver than 100 million yuan worth of solar lights, Lam 30 Silver held in the evening lighting ceremony.

Lake Park to spend the solar street light
Recently, Lake Park, recycled water supply station of the emergence of a huge solar energy "awning", which is Wuxi's fifth solar street light station. The main roof of the station 21 sets 100W LED illumination, 9 sets of lights and LED light ceiling lighting 90W LED light tube power supply, the annual power generation of 1.5 million degrees.
In 2008, Wuxi began to solar lighting system to carry out research work, then have built five solar street light plant, the largest one in Lake Park tse River wetlands. Reporters at the Lake Park citizens around the square Rucker Road to see the road, all the way to the top of the poles have a "sunflower" look like solar panels, these new solar lights is complementary to the mains. At the Civic Center building in the southeast, is a solar power plant of the street, which consists of 12 groups of huge solar panels composed of silver, electric plate angle was 45 ° stretched to the sky to receive the energy from the sun, the proceeds will be temporarily stored electrical up, then store the energy distribution of the night to a nearby tse River a lake of 113 sets of lights and lawn use.
"The use of off-grid photovoltaic power station the way, with a 192 high single crystal silicon solar panels. Its use of the DAY-type bracket may at any time to track the sun panels toward the direction of conversion, fully absorb the sun." Wuxi Lighting Management Department official said, the station was saving 37 900 degrees, saving 13.67 tons of standard coal, 33.14 tons of carbon dioxide emissions, emissions of sulfur dioxide 108 kg.
It is understood that the entire solar street light system consists of five power stations, a few years ago, solar lighting had been introduced in Wuxi city lighting engineering, land horse line was first installed on many street a small solar panel, at present, the city's total this class of solar lights 1660. 13 street lighting and landscape lighting 5, total annual savings of 324,500 kWh, saving coal 129.8 tons of carbon dioxide emissions 32,000 tons, 9.74 tons of sulfur dioxide emissions.
