solar LED lighting products is a new generation of green lighting products, its main components including solar photovoltaic cells ( PV technology) And semiconductor lighting source ( 领导) 。 Because the LED solar lamp integrates the advantages of solar photovoltaic and LED solid-state lighting solar LED lighting system, implements a new generation of energy and the perfect combination of new light source.

with the development and progress of solar photovoltaic technology, solar cells, as a kind of new energy, first in terms of civil application in lighting lamps and lanterns, solar lighting products due to the dual advantages of environmental protection and energy saving. Solar led lighting products is a new generation of green lighting products, its main components including solar photovoltaic cells ( PV technology) And semiconductor lighting source ( 领导) 。 Because the LED solar lamp integrates the advantages of solar photovoltaic and LED solid-state lighting solar LED lighting system, implements a new generation of energy and the perfect combination of new light source. But, in the design of solar lighting lamps and lanterns, light source, solar battery, storage battery charging and discharging control many factors, including any link problems will cause defects.

a, first to learn about the solar lamps and lanterns:

solar photovoltaic power generation technology can with perfect combination of LED lighting is the key to both for the low voltage direct current (dc), and can match each other. So a combination of both don't need to solar cells produce direct current into alternating current (ac), thus greatly improving the efficiency of the entire lighting system. At the same time, by using grid technology or use battery energy, make its advantages more apparent. 1, solar panels

2, design problems that should pay attention to when using: ( LED lawn lamp, for example)

1, the characteristics of the LED is close to the zener diodes, working voltage change 0, 1 v, about 20 ma current job may change. For safety, normally use series current limiting resistor, great energy loss is obviously not suitable for solar energy lawn lamp, and LED brightness change with working voltage. The booster circuit is a good idea, you can also use simple constant current circuit, anyhow must automatic current limit, otherwise will damage the LED.

2, general LED the peak current of 50 ~ 100 ma, reverse voltage of 6 v or so, be careful not to exceed this limit, especially in solar cells reverse or battery, light, high peak voltage booster circuit, is likely to exceed this limit, damage to the LED.

3, LED temperature characteristics, temperature 5 ℃, the flux decline 3%, use should pay attention to summer.

4, working voltage large discreteness, the same model, LED the working voltage of the batch has certain differences, should not be used in parallel. You have to use a parallel flow should be considered.

5, super bright white LED color temperature of 6400 k to 30000 k. At present, the low color temperature of super bright white LED is still not to enter the market, thus made of ultra-high bright white LED solar lawn light penetration is poorer, so should pay attention to in the optical design.

6, electrostatic of ultra bright white light L how much impact on the ED solar street lamps, when installation should have anti-static facilities, workers should wear anti-static wrist. Ultra-high bright white LED by electrostatic damage might be naked eye look not to come out, but will shorten service life.
