Solar LED lights are new green lighting products, consist of solar photovoltaic cell and semi-conductor LED.
Solar LED light system is a perfect combination in view of solar LED light integrated advantages with solar PV and LED solid light. With the growing development and progress of solar photovoltaic technology, solar cell as a new energy firstly be applied to luminous products, and the solar light own double advantages both environment protection and energy saving.

Solar LED light is new green light product, it is consist of solar photovoltaic cell and semi-conductor LED. Solar LED light system is a perfectly combination, that is because solar LED light integrated advantages of solar PV and LED solid light. But when design solar light, there are many elements will be involved, such as, light source, solar cell system?storage battery charging or discharging, any element may cause default.
The reason why solar PV technology could combination with LED lighting perfectly is that they are both direct current, has low voltage and could match for each other without power transform, as a result, the whole lighting system's power enhanced greatly. Meantime, rely on integration technology or utilize storage battery charging or discharging energy, the advantage of solar system become more obvious.
Solar cell 's using life is more than 25 years, however, common battery's is 2~3 years, so storage battery is the weakest component for solar power system, which should be improve urgently. yet, Storage capacity could solve this problem to a certain extent for its using life over 10 years, in addition, the control circuit of storage capacity is quite simply, but the expensive price results usage limitation.
In a word, solar cell is a giant PN joint, it transform solar power into electric power, LED light is another PN joint that could transform electric power to light, and the conversion efficiency is keeping increase, we are sure solar light will arrive to LED light's using requirement in the near future, however, at then its using life can up to 100,000 hours above, that is the actual green light.
