Green lighting refers to the use of high efficiency, long life, safety and stable performance of lighting based products (electric light source, lamp electrical accessories, lamps, wiring equipment, as well as dimming controllers and light control devices) through scientific lighting design to improve the conditions and quality of people's work, study and life. In order to create an efficient, comfortable, safe, economic, beneficial environment and fully reflect the modern civilization of lighting.

In January 1991, the US Environmental Protection Agency (EPA) first put forward the concept of implementing "Green Lights" and promoting the "Green Lights Program", which soon won the support of the United Nations and the attention of many developed and developing countries. And actively take the corresponding policy and technical measures to promote the implementation and development of green lighting project. In November 1993, China's State Economic and Trade Commission began to launch the China Green Lighting Project, which was officially listed in the national plan in 1996.

Green lighting refers to the use of high efficiency, long life, safety and stable performance of lighting based products (electric light source, lamp electrical accessories, lamps, wiring equipment, as well as dimming controllers and light control devices) through scientific lighting design to improve the conditions and quality of people's work, study and life. In order to create an efficient, comfortable, safe, economic, beneficial environment and fully reflect the modern civilization of lighting.
From the above concepts:

1. The lighting project must implement the sustainable development strategy, put conservation in the first place, and improve the efficiency of resource utilization. Because green lighting can save electric energy, saving electric energy is of great significance to protect the environment.
2.The green lighting includes electric light source, electrical accessories, lamps and lanterns, wiring equipment, as well as dimming and light control devices and other reasonable use. For example, the use of high efficiency and energy saving electric light source:
1) Replace ordinary incandescent lamps with halogen tungsten lamps (save 50-60%);
2) replace incandescent lamps with self-ballasted single-ended fluorescent lamps (power saving 70-806);
3) the replacement of incandescent and straight fluorescent lamps with straight fluorescent lamps (energy saving 70-906);
4) vigorously promote the application of high pressure sodium lamp and metal halide lamp;
5) the application of low pressure sodium lamp;
6) Promote the application of light-emitting diodes (LEDs).

High efficiency and energy saving lighting fixtures:
1) Choose reflective lamps with reasonable light distribution, high reflection efficiency and good durability;
2) Choose lamps and lanterns that are compatible with the light source and electrical accessories. Using high efficiency and energy saving lamp electrical accessories: using energy-saving inductive ballast and electronic ballast to replace the traditional high energy consumption inductive ballast. Using a variety of lighting energy-saving control equipment or devices :1) light sensor (2) thermal radiation sensor (3) ultrasonic sensor (4) time program control (5) direct or remote dimming.
3. Green lighting aims to improve people's working, learning and living conditions and quality, so designers must have a good understanding of the requirements of green lighting and grasp the relevant national lighting design specifications to meet the requirements.

   Green lighting purpose:
1. Protect the environment, including reducing pollutant emissions during the life cycle of lighting appliances, using clean light sources, natural light sources and green materials to control light pollution;
2. Save energy. For example, replacing incandescent lamps with compact fluorescent lamps can save more than 70% of electricity.
3. Healthy, comfortable, pleasant and safe high quality lighting environment;
4. Productivity is more valuable than saving money on electricity bills.
5. Create a light culture that reflects modern civilization.
