Advantages of LED light sources

LED has many advantages, the major advantages are as follows:

1. voltage: LED 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 power supply, especially in public places.

2. efficiency: energy 80% lower than with the luminous efficiency of incandescent lamps

3. applicability: very small, LED small pieces of each module is 3-5mm square, device fabrication into a variety of shapes, and appropriate to the volatile environment

4. stability: 100,000 hours, lumen 50% of the initial

5. response time: its incandescent millisecond response time, LED light response time with nanosecond

6. environmental pollution: no toxic metal mercury

7. color: change the current color, led easily through chemical modification methods, adjusting the material band structure and band-gap, achieve the color red yellow green blue orange glow. Such as when a small current to red LED, as the current increases, followed by Orange, yellow, and finally Green

8. price: LED prices are more expensive, compared to incandescent bulbs, several LED price equivalent to the price of an incandescent, often with each set of lights by 300~500 on diodes pose.sourcechipglen
