With the increasingly poor resources of the earth, the cost of investment in basic energy increasingly rising, all kinds of safety and pollution hidden dangers are everywhere, solar energy as an "inexhaustible" security, environmental protection of new energy more and more attention. At the same time, with the development of solar photovoltaic technology and progress, solar lighting products in environmental protection and energy-saving dual advantages, Solar street lamps, garden lights, lawn lights and other aspects of the application has gradually formed a scale, solar power in the field of street lighting development has become increasingly perfect.
LED light source as a green light source, with high luminous efficiency, less power consumption, long service life, strong security and reliability characteristics, led single tube power 0.03 ~ 0.06 Watts, using DC drive, single tube drive voltage 1.5 ~ 3.5 Volts, current 15 18 Ma, reaction speed, can be in high-frequency operation, the same lighting effect, the power consumption is incandescent bulb one out of 10,000, fluorescent tube one-second, Japan estimates, such as the use of light efficiency than fluorescent lamps are twice times higher than the led to replace the Japanese half of incandescent lamps and fluorescent lamps, annual savings equivalent to 6 billion liters of crude oil. On the bridge Guardrail light example, the same effect of a fluorescent lamp more than 40 watts, and the use of LEDs per branch of power only 8 watts, and can be colorful changes.
With the development of economy, the lighting power of our country will be greatly improved, green energy-saving lighting research and application, will be more and more attention, on this basis, someone began to associate LED light source with solar energy, hoping to allow night lighting can be combined with the solar energy reserves during the day, this will be a big step in green environmental protection.
