Currently has the capacity to produce LED and LED lighting manufacturers also one of the few, different manufacturers use different quality LED LED lighting is caused by an important reason for different prices. What are the characteristics of the LED light source?
(1) Voltage: led using low voltage power supply, power supply voltage between 6-24V, varies depending on the product, so it is a more secure than using a high voltage power supply, especially for public places.
(2) Performance: consumption of energy compared with incandescent light efficiency 80% reduction.
(3) Applicability: small, small piece of each unit LED 3-5mm square, it can be prepared into various shapes of devices, and for the environment variable.
(4) Stability: 100,000 hours, the light fades to the initial 50%.
(5) Response time: the incandescent millisecond response time, LED lights nanosecond response time.
(6) of environmental pollution: no harmful metal mercury.
(7) Color: change the current color, light-emitting diodes by chemical modification methods to easily adjust the material’s band structure and band gap, to achieve multi-color light orange red Huanglv Lan.
(8) Price: LED’s price is expensive, compared to incandescent lamps, the price of a few LED incandescent lamp with a price considerably.
