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

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

3. Stability: 100000 hours, light attenuation is 50% of the initial value.

4. Echo time: the echo time of its incandescent lamp is millisecond, and the echo time of LED lamp is nanosecond.

5. Environmental pollution: no harmful metal mercury.

6. Color: changing the current can change color. The LED can easily adjust the energy band structure and band gap of the data through chemical modification to realize multi-color luminescence of red, yellow, green, blue and orange. For example, the red LED at low current can turn orange, yellow and finally green with the increase of current.
