LED lighting value of the
energy crisis, the greenhouse effect and the ecological environment deteriorating moment to remind people that the Earth has been exhausted, to change people's access to energy and improve energy efficiency has become the consensus of the people of the world.
In the structure of the world's electricity use, electricity for lighting accounts for about 19% of the total electricity consumption; British Brian Edwards pointed out that in the preparation of the "sustainable architecture" in which the total energy consumption in the UK About half of the construction-related building artificial lighting energy consumption accounted for 15% of the total building energy consumption to 50%; electricity for lighting in our country accounts for about 12% of the country's total electricity consumption, China’s annual lighting electricity consumption growth rate (a conservative estimate) of about 5%. Can be seen from the above data, due to the different levels of economic development of countries, the proportion of electricity for lighting different, but the lighting energy consumption has become an important part of the national energy consumption. Lighting energy conservation issues have become a thorny issue for governments and professionals must face.
