Lighting is a form of energy,which requires electric power and electric equipment.Lighting accounts for a large proportion of the energy consumption in buildings. In order to improve energy efficiency and save energy and reduce pollution, energy-efficient lighting should be encouraged. Energy-saving lighting mainly refers to LED lighting,high-efficiency fluorescent lamps and condensed fluorescent lamps. LED lighting is a kind of solid light source, It is an energy-saving, environmentally friendly, low-carbon and safe lighting.LED lighting has the characteristics of safety, long life, low power consumption, high brightness, vivid color, no flicker and so on.Thus LED lighting has become the most popular energy-saving lighting. High-efficiency fluorescent lamps and condensed fluorescent lamps are two types of energy-saving lamps, which are usually used for lighting in shopping malls, office buildings and other places. Compared with ordinary lamps, they can achieve the same effect with lower power consumption and form energy-efficient lighting. Good lighting and reasonable choice of lighting can not only improve the working/living environment, but also reduce energy waste and protect the environment. Therefore, in the coming future, energy-efficient lighting should be the mainstream of the market.
