How To Distinguish The Power Of LED Chip

- Mar 10, 2018 -

1. Type.

◆Small power (such as 5mm straw hat, 5mm spotlight, 3528 encapsulation, etc.), about 0.06W.

◆Medium power (such as 8mm straw hat, 10mm straw hat, 5050 encapsulation, etc.) 0.2W-0.5W.

◆High power 1W, 3W, 5W, 10W... 100W.


Two. Characteristics

1. voltage: LED clip with a low voltage power supply, power supply voltage is between 2-4V, according to different products, so it is a more than the use of high voltage power supply; power supply safety, especially suitable for public places;

2. current: the working current is 0 - 15mA, and the brightness increases with the current.

3. performance: incandescent energy consumption is reduced by 80% when.

4. applicability: very small, each unit LED chip is 3-5mm's Square, so it can be made into various shapes of devices, and is suitable for changeable environment.

5. stability: 100 thousand hours, 50% for the initial decay.

6. response time: the response time of the incandescent lamp is millisecond, and the response time of the LED lamp is nanosecond.

7. to environmental pollution: no harmful metal mercury.

8. color: changing the current can change color. Light emitting diodes easily adjust the band structure and band gap of materials through chemical modification, and achieve red, yellow, green and orange multi color emission. If the small current is red LED, with the increase of the current, it can turn into orange, yellow, and finally green.

9. price: the cost price corresponding to the traditional LED clip source is more expensive than incandescent lamps, dozens of white LED, the price you can with a price of incandescent lamps, but usually each signal need is composed of 300~500 diodes.
