The emitting diode can be transformed into light energy through electrical energy, so it is used in the field of lighting. At the same time, compared with incandescent bulbs and lanterns, the light emitting diode is the following characteristics.

1. There is a lower working voltage during use.

2. The required working current is relatively small.

3. It can have good impact resistance and seismic effects, and longer service life.

4. Be able to use the strength of the current to change the light intensity.

The above are the characteristics of incandescent light bulbs and lanterns, and the characteristics of glow diodes have the characteristics.
