As a new generation of light source, LED point light source is very different from traditional thermal radiation and gas discharge light sources (such as incandescent lamp, high pressure sodium lamp). The current LED point light source has the following advantages in lighting:
1. Good shock resistance and shock resistance
The basic structure of LED point light source is that the electroluminescent semiconductor material is placed on the lead frame, and then sealed with epoxy resin around it. There is no glass shell in the structure. There is no need to vacuum or fill the tube with a specific gas like an incandescent or fluorescent lamp. Therefore, LED light source has good seismic and shock resistance performance, which brings convenience for the production, transportation and use of LED light source.
2. Security and stability
LED point light source can be driven by low voltage DC. In general, the power supply voltage is between 6 ~ 24 V, with good safety performance, especially suitable for use in public places. In addition, in a better external environment, the light source has less light attenuation and longer service life than the traditional light source. Even if it is opened and closed frequently, its service life will not be affected.
3. Good environmental performance
Because the metal mercury is not added in the production process of LED point light source, it will not cause mercury pollution after being discarded, and the waste can be recycled, save resources and protect the environment.
4. Fast response time
The response time of incandescent lamp is MS and that of lighting is nanosecond. Therefore, it has been widely used in the field of traffic lights and car lights.
5. The brightness is adjustable
According to the principle of LED point light source, the brightness or output flux of LED point light source changes with the current basic positive changes. Its working current can be large or small in the rated range, and has good adjustability, which lays a foundation for the realization of user satisfaction lighting and stepless brightness control of LED point light source
