Description
Skill is stated the field
The utility model relates to a kind of semiconductor light-emitting-diode solar street lamp controller circuit.
The background skill is stated
It is uneconomical, not environmental protection that using solar photovoltaic generates electricity to traditional lamp light source power supply.The one: traditional light fixture power consumption is all bigger, and all is that use is absolutely unsafe in high pressure (as: 110V, 220V, 380V even higher) work down; Must increase the inversion link of boosting with the solar power generation power supply, reduce rate of energy (good inverter efficiency is about 90%, and about general inverter 70%-80%, poor is just lower) so again.The 2nd: conventional light source such as electricity-saving lamp, light efficiency be than higher, but the life-span very short (3-5 month just bad, good can near 1 year), power saving does not save money, and discarded after stain is also very serious, even if gaseous discharge lamp also has only 3,000-10,000 hours.The 3rd: what solar cell produced is direct current, and inversion must be provided; The conversion efficiency of solar cell also not too high (the general product for civilian use about 14%), the electric energy that is produced is limited, can not satisfy the long-time needs of high power load; If just simple increase solar cell area cost is too high again, be unfavorable for the solar product popularization.
Along with the development of solid-state physics and semiconductor lighting technology, human development has gone out the 4th generation light source-solid light source LED (first on behalf of incandescent lamp, and second on behalf of fluorescent lamp, and the third generation is a gaseous discharge lamp).LED has energy-conservation (than also power saving 15% of electricity-saving lamp), pollution-free, long-life (100,000 hours) but, light efficiency high FREQUENCY CONTROL, advantage such as non-maintaining, pollution-free, prediction according to Commission Internationale De L'Eclairage, to 2010 the 4th generations light source as the illumination popularity rate, Japan is 100%, the U.S. is 50%, and China is 15%.Along with improving constantly of semiconductor light-emitting-diode production technology, developed brightness blue light LED, produce white light by the blue-ray LED excitated fluorescent powder, making LED substitute traditional lighting becomes possibility.At present, LED brings into use the domestic decoration that also is mainly used in abroad as illumination.Because its vast potential for future development, China Department of Science and Technology has also started the semiconductor lighting plan in June, 2003.
Give the power supply of LED illuminator with solar energy, energy utilization rate height not only, nor contaminated environment.Because solar cell is to be direct current with phototransformation directly, and the operating current of LED own also is a direct current, (as: inverter etc.) loss of can cutting down the number of intermediate links.Even if LED is low in energy consumption simultaneously, does not pollute environment the high damage of brightness back yet.Therefore combine the street lamp illumination system of formation with LED be a lighting energy saving environment friendly system that efficient is high to solar photoelectric.This system is made up of solar module, the light emitting source that is integrated with a plurality of superbright degree semiconductor light-emitting-diodes (LED), street lamp post, lamp holder, street lamp charging-discharging controller, maintenance-free lead-acid battery, control cabinet.
