What are the advantage of LED?
1. Optical efficiency: spectrum almost all concentrated in the visible light frequency, efficiency can reach to 80%-90%.
2. High-quality light as a result that is no ultraviolet and infrared of spectrum, and is typically green lighting.
3. Small Energy Consumption: single-power general in the 0.05-1w, through the cluster can be tailored to meet different needs,and waste little.
4. Long lifetime: flux attenuation to 70% of standard life expectancy is 100,000 hours.
5. Durable and reliable: No tungsten wire, glass and other easily damaged components, few non-normal retirement rate, and with very low maintenance costs.
6. Flexibility of application: small size, can flat pack, easy to develop into a short thin products, and can make various forms such as point, line, fact of specific applications.
7. Security: working voltage is 1.5-5v or less in between, and the current is 20-70mA in between.
8. Green: the waste can be recycled and of no pollution. Unlike fluorescent lamps that contains mercury as ingredients.
9. Short response time: can adapt to frequent switching and high-frequency operating occasions.
