What are the advantages of LED neon lights over ordinary neon lights?

LED has the following characteristics:

1. voltage: LED uses low-voltage power supply, the power supply voltage is between 6-24V, which varies according to different products, so it is safer than using high-voltage power supply, especially suitable for public places.

2. Efficiency: Compared with incandescent lamps with the same light efficiency, the energy consumption is reduced by 80%.

3. Applicability: Very small, each unit LED chip is 3-5mm square, so it can be made into devices with various shapes and is suitable for changing environments.

4. Stability: 654.38+100000 hours, and light attenuation is 50% of the initial value.

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

6. Environmental pollution: no harmful metal mercury.

7. Color: the color can be changed by changing the current, and the energy band structure and band gap of the material can be easily adjusted by chemical modification of the light-emitting diode, so as to realize multicolor emission of red, yellow, green, blue and orange. For example, an LED that is red at low current can turn orange, yellow and finally green with the increase of current.
