A brief overview of the special nature of solar lights

Solar street light is a typical independent photovoltaic power generation system, this is just one aspect of the problem, even more serious is that it is a reduction in the amount of solar radiation with the increased seasonal loads. You can see from the above analysis, the annual winter solstice is the minimum amount of solar radiation, which is generating the least amount of solar components, when the annual winter solstice is the shortest day, longest night, when the longest road lighting needs . Currently in the design of solar street lighting problems people are concerned about the continuous rainy days, in fact, this problem is still relatively easy to solve, as long as the increase in the capacity of the battery can be a part of, if you want the winter solstice of road lighting indicators meet the state standards requirements, unless sacrifice spring, summer, autumn generation solar cell modules, no other way. In this case the efficiency of the system will be very low.
In the solar cell power source efficiency in certain circumstances, factors that affect the use of solar street light effects, there are many: the intensity of solar radiation, the solar cell module tilt angle is reasonable, ambient temperature, battery recency (charging old battery and power generation Efficiency can be a difference of more than 30%) and the like. In the absence of these conditions previously determined to evaluate the effect of solar lights is inaccurate.
(1) "can light" does not mean that can meet the state standards CJJ45-2006. Urban road lighting design standards road illumination. Some of the case.
The output power of the light source can vary with the battery voltage, the lower the voltage, the output power is smaller, the illuminance is smaller.

This issue is very important, it even determines the service life of solar lawn, up to 10-20 times the starting current three-color color energy efficient lamps started, the system in such a large withstand voltage current situation may have dropped substantially, Solar Lawn not start or start again until the damage.
5.6 boost circuit efficiency and impact of LED lights
Small power solar lawn generally boost circuit, if the oscillation circuit, inductor boost. Inductor using standard color code inductors, standard color code inductor using an open magnetic circuit, a large loss of flux, so low circuit efficiency. If a closed magnetic circuit inductor boost manufacturing, such as magnetic, boost circuit efficiency will be greatly improved. Properties close to the Zener diode LED <http://www.ledgb.com>, working voltage 0.1V, operating current may vary approximately 20mA. For security, under ordinary circumstances the use of a series current limiting resistor, great energy loss is obviously not suitable for solar lawn lights, and LED brightness varies with the operating voltage, and must automatically limit, otherwise it will damage the LED. General LED peak current 50-100mA, anti-reverse-battery or battery energy load, is likely to exceed this limit peak voltage is too high when the booster circuit, damaged LED.In recent years, China's optoelectronics industry has shown rapid growth, has formed a specialized, large-scale photovoltaic industry chain. The state supports photovoltaic building demonstration, implementation of the "Solar Roofs Plan", the financial support for the implementation of solar energy utilization policy.
