Background technology
In recent years, energy problem has become the most important problem of puzzlement countries in the world economic development, because oil, coal equal energy source is non-renewable, and, caused being on the rise of energy problem, and the pollution problem that in use brings of oil, coal equal energy source to the expansion day by day of energy demand, also brought extremely ill effect to environment, warming day by day of global climate, extreme weather increasing all has direct relation therewith.And electric energy is as a kind of clean energy resource, it has multiple source, can obtain from number of ways such as solar energy, wind energy, tide energies, and electric energy also makes the most widely used a kind of energy in people's daily life, the running of machinery equipment, the use of household electrical appliance, and, all using electric energy with the automobile of electric energy as power.But along with increasing day by day that electric energy uses, the imbalance between supply and demand of electricity is also increasing, though country all in the investment that increases power plant, has built large quantities of hydroelectric generations, solar power station, wind power station, heat power station, still can not satisfy increasing need for electricity always.
In order to solve this contradiction, using electricity wisely, cutting down the consumption of energy has become more and more people's common recognition in current society.In all power consumptions, electric consumption on lighting has accounted for 12%, and street lamp electricity consumption, city illumination electricity consumption, Landscape Lighting answer electricity consumption to account for bigger proportion in the middle of the electric consumption on lighting, the lighting apparatus that it adopted is again based on old-fashioned incandescent lamp, high-pressure sodium lamp, sodium vapor lamp, and this class lighting apparatus, have shortcomings such as caloric value height, phototranstormation efficiency be low, caused the significant wastage of electric energy.And adopt the lighting apparatus of led light source, can under the situation that guarantees same brightness of illumination, can reduce 1/2 or more even 2/3 above power consumption, so will become the main body in market gradually as the lighting apparatus of light source with led; In some developed countries economize on electricity industries are every year in hundred billion dollars huge market, and the Chinese government also in recent years energy-conservation as the opera involving much singing and action of economic development, country given aspect a lot of green energy resource, economize on electricity engineering many economically with policy on support, and a lot of city also all has been placed on energy industry the status of first developing.
