Description
Technical field
The utility model relates to technical field of lighting fixtures, is specifically related to a kind of wind, light, the complementary power supply of electricity LED lighting controller drive circuit.
Background technology
The world today, main energy sources such as oil, coal, natural gas are faced with the danger of resource exhaustion, from the time average less than that exhausts of fossil fuel (oil, coal, natural gas etc.) of counting the whole world now 100 years, and the illumination energy consumption was one maximum in all energy resource consumptions.Simultaneously, exploitation that fossil energy is a large amount of and utilization bring serious environmental to pollute, and environmental protection pressure constantly increases.Wind energy and solar energy are the novel energies of cleaning, and fully developing wind energy and solar energy has become the STRATEGIES OF SUSTAINABLE DEVELOPMENT decision-making of countries in the world government.
Wind energy is a kind of most active clean energy resource, and wind power generation has the following advantages: use cleaning, cost is lower, and is inexhaustible; It is big that wind power generation has the installed capacity growth space, and cost descends fast; Safety, the energy is never exhausted; Wind power generation can reduce a large amount of pollutants and the carbon emission that the fossil fuel generating produces, and can effectively alleviate air pollution, and water pollutes and global warming issue; Wind generating technology is ripe relatively, and the generation mode with large-scale development and business development condition.
Solar power generation is a kind of important form that solar energy utilizes, and is that to adopt solar cell be the generation mode of electric energy with transform light energy, and along with technology is constantly progressive, and photovoltaic generation might be one of generation technology of tool development prospect.Utilize solar power generation to have following advantages: no need of any fuel, pollution-free, noiselessness does not have any waste material and discharges, as long as there is sunlight to generate electricity; Solar energy is inexhaustible, does not have exhausted danger; Be not subjected to the restriction of resource distribution and region, solar energy is widely distributed, can generate electricity nearby in electricity consumption place, must not grow distance and carry, and has reduced the loss on the circuit; Solar energy is without fuel, and operating cost is little; Output DC during solar cell working; Do not have moving component in the system, the reliability height is safeguarded simple.
(Light Emitting Diode LED) is considered to the new light sources of 21 century most worthy to semiconductor light-emitting-diode, becomes the leading of illumination market with replacing incandescent lamp and fluorescent lamp.The application prospect of White-light LED illumination has started climax in the whole world, has been expressed great expectations.Compare with traditional lighting source, white light LEDs has the following advantages: the luminous efficiency height, and theoretical luminous efficiency reaches 200lm/W, far above incandescent lamp and fluorescent lamp; Electricity-saving lamp has been a great beginning than incandescent lamp energy-conservation 4/5, and LED is than electricity-saving lamp also energy-conservation 1/4; No poisonous metal mercury, no infrared ray and ultraviolet radiation; Volume is little, can realize the encapsulation of multicore sheet, is easy to integrated; Mostly be solid-state encapsulation, the reliability height; Life-span is long, and the theoretical life-span reaches 100,000 hours, is longer than the traditional lighting light source; Low-voltage direct drives; Response speed is fast, is easy to carry out digital control.
Mainly there is following drawback in China's city street lamp illumination at present: the conversion efficiency of (1) present photovoltaic cell is also lower, the finite energy that is produced, if the just simple area that increases solar cell, cost is too high, is unfavorable for product promotion; (2) traditional light fixture power consumption is all bigger, and all is the use of under high pressure working, and is absolutely unsafe, and increases the inversion link of boosting, and reduced rate of energy again, and the conventional light source light efficiency is all lower, and the life-span is all very short; (3) function is fixed, and can not effectively change according to the scene, is fit to field requirement, and continuous when overcast and rainy, because energy storage device electric weight deficiency, street lamp does not often work, and influences urban life; (4) defencive function is single, because employing is that the microcontroller chip function is few, can not effectively protect system; (5) because on-the-spot major part is a triangular web, do not have the communication between taking into account system, be restricted in the development afterwards; (6) other building and the greening of urban road has the effect of sheltering from heat or light to photovoltaic battery panel, causes the photovoltaic battery panel cisco unity malfunction, and solar street light can't be installed and used; (7) after all urban roads, highway, industrial area, living area road, street lamp were turned on light from the dusk, just bright to point in early mornings 6 always, this had not only shortened the useful life of lighting, also wastes a large amount of electric energy, has caused white elephant to government finance; (8) characteristics of power supply grid are that voltage is relatively low when load increases; When load reduced, voltage was higher relatively, and for this class gas discharge device of street lamp, Pedestrians and vehicles is happened peak times of power consumption more for a long time in the first half of the night, and voltage is lower, and brightness is darker.And enter midnight, and network load descends, and acute liter of voltage causes its illumination bright unusually, even dazzle occurs, not only causes unnecessary waste of energy, and reduced the useful life of light fixture greatly.
Wind light mutual complementing LED illumination is main means of development and use solar energy and wind energy, yet, because the discontinuity and the intermittence of solar radiation, and the at present investment and the reason such as cost is higher and the part technology is not mature enough of simple photovoltaic lighting system, photovoltaic lighting system often occurs: continuous when overcast and rainy, since the battery tension deficiency, the situation that the LED load can not be lighted.
