(1) Small size
Compared with traditional light sources, LED light sources are small in size and light in weight, and can be made into devices of various shapes, which are convenient for the arrangement and design of various lamps and equipment, and have strong adaptability and wide application range.

(2) Good environmental performance

Since the LED light source does not need to add metal mercury in the production process, the LED will not cause mercury pollution after it is discarded, and almost all of its waste can be recycled, which not only saves resources, but also protects the environment.

(3) Safe and stable

The LED light source can be driven by low-voltage direct current, and the general power supply voltage is between 6~24V, so the safety performance is better, especially suitable for public places. In addition, under the conditions of good external environment, the LED light source has less light decay and longer life than the traditional light source. Even if it is switched frequently, its service life will not be affected.

(4) Good seismic and impact resistance

The basic structure of the LED light source is a piece of electroluminescent semiconductor material, which is placed on a lead frame, and then sealed with epoxy resin around it. There is no glass casing in the structure, and it does not need to be in the lamp tube like incandescent or LED Street Light YASL-21M fluorescent lamps. Vacuum or flush specific gases. Therefore, the LED light source has good shock resistance and impact resistance, which brings convenience to its production, transportation and use.

(5) Strong directivity

Compared with the traditional light source, the light emitted by the LED light source is directional, most of the light emitted from the LED can be directed to the illuminated surface, and the utilization rate is much higher than that of the traditional light source.

(6) Fast response time

The response time of incandescent lamps is in milliseconds, and the response time of LED light sources is in nanoseconds. Therefore, it is widely used in the field of traffic signals and car lights.

(7) High luminous efficiency

With the development of LED lighting technology, the luminous efficiency of LED light source has been increased from less than 10lm/W to more than 100lm/W, and its luminous efficiency still has the potential to be greatly improved.
