LED structure and luminescence principle

LED the basic structure is an electroluminescent semiconductor materials, placed on a wire rack, then sealed with epoxy resin around, praying functions to protect the internal core, so the LED of the seismic performance is good.

The characteristics of LED light source

1. Voltage: LED USES low voltage power, and the power supply voltage is between 6 and 24V, depending on the product, so it is a more secure power than the use of high-voltage power, especially in public places.

2. Effectiveness: the energy consumed was 80% lower than that of incandescent bulbs.

3. Applicability: small, each unit LED small chip is 3-5mm square, so it can be prepared into various shapes of devices, and suitable for changeable environment.

4. Stability: 100,000 hours, with the initial 50%.

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

6. Environmental pollution: no harmful metal mercury.

7. Color: changing the current can change color, and the light-emitting diode can easily modify the band structure and bandgap of the material by chemical modification method, so that the red and yellow and green blue orange glow. If the small current is red LED, with the increase of current, can be orange yellow finally is green.

8. Price: the price of leds is more expensive, compared with incandescent lamps, the price of several leds can be comparable to the price of an incandescent lamp, which usually consists of 300 to 500 secondary tubes.

The application of the LED

Initially LED is used as the indicator light instrument and then all kinds of light color of LED traffic light and display screen has been widely applied in large area, produced good economic and social benefits.
