As is known to all, now has been gradually replaced by the solar street lamps to replace traditional lamps. Solar street lamps by solar energy battery components, super bright LED lamp, rechargeable and maintenance-free battery, the active control circuit, lamps, etc. Now most of the street lamps use LED as light source, LED long service life, can be more than 100000 hours, low voltage things and very well applied in solar street light. Especially is LED skills have the key breakthrough, and its characteristics in the past five years has very fierce progress, its performance price ratio have great progress. Other LED by the low voltage dc power supply, its light source control capital is low, the modulation of light and shade, frequently switch all be about, and won't inoculation of adverse influence on the performance of the LED. Solar street lamps step-up IC, able to take the initiative to charge and discharge behavior hold switch, when the day is solar battery charging board feel to sunny, active switch to close the light into the charging status, when the night is to solar battery charging board feel less than the sun, in the active switch to the state of battery discharge? The lights. Solar street lamps step-up IC, can put 1. 5 volt rechargeable battery output voltage is promoted to 3. 6 volt. Solar street lamps use solar energy to hold important matter, when the daytime sunlight on solar cells, the light energy into electrical energy storage in the battery change, again by the LED battery for street lights at night, Light emitting diodes) Provide power supply, it is energy saving, convenient, environmental protection, etc. Practical in the residential community green grass beautification lighting whitewash, park lawn beautification whitewash. Solar street lamps light source and power system plan main point because of his strange solar street light strengths, than to get quick growth. Street lamp power is small, important to decorate as the goal, to require high mobility, circuit laying difficulties, waterproof demanding garden and practical. This makes the street lamps by solar batteries showed many ancient did not have the upper hand.
