Led is a semiconductor solid light-emitting device: it has the advantages of small size, light weight, high brightness, low energy consumption, long life, high safety, high color purity, good direction, low maintenance cost, environmental protection and no pollution.
Led lighting is a kind of green light source: low working voltage, less power consumption; Stable performance, long life (generally 100,000 hours); Strong impact resistance and vibration resistance; Led lighting products can provide high-quality light environment, improve the light efficiency of the lighting system, no infrared and ULTRAVIOLET components, high color rendering and has a strong light direction; Good dimming performance, no visual error when color temperature changes; Low calorific value of cold light source makes it safe to touch. Improve glare, reduce and eliminate light pollution. Zero stroboscopic, no eye fatigue phenomenon. No electromagnetic radiation, prevent radiation pollution to protect the brain.
It can not only provide a comfortable lighting space, but also meet people's physiological health needs. It is a healthy light source of environmental protection.

Disadvantages:
1. Expensive;
2. There is still a big gap between the universally achievable optical efficiency and theoretical optical efficiency;
3. There is still a big gap between the life that can be achieved and the theoretical life (100,000 hours);
4. There is a certain amount of calorific value;
5. Light decline can also be greatly reduced.
