Energy Star (Star Energy), is a leading U.S. government, mainly for consumer electronics energy saving plan. Energy Star Program in 1992 by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of energy (DOE), the purpose is to reduce energy consumption and reduce greenhouse gas emissions. The program was subsequently adopted in Australia, Canada, Japan, Taiwan, New Zealand and the European union. The program is voluntary, energy star standards are generally more than the United States federal standards for energy saving 20-30%. The earliest products such as computer and other information appliances, after gradually extended to the motor, office equipment, lighting, home appliances, etc.. Later extended to the building, the United States Environmental Protection Agency (EPA) in 1996, actively promote energy star building plan, by the Environmental Protection Agency (EPA) assist voluntary industry evaluate the building energy usage (including lighting, air conditioning, office equipment etc.) and planning of the building energy efficiency improvement action plan and follow - up work, so some imported environmental protection new concept of homes and commercial buildings can also find the sign of the energy star.

Energy Star contains the test content: security, EMI, surge, noise (non energy star energy efficiency test project);

Optical performance and energy efficiency test items: 1, luminous efficiency, luminous flux 2, color temperature, color deviation, color index 3, intensity distribution, regional flux distribution 4, color spatial inhomogeneities 5, switch cycle 6, Guangtong maintenance rate 7, color maintenance rate of 8, 9 dimensions and electric parameters.
