As a new generation of light source, LED point light source adopts built-in LED cold light source, which can emit different colors according to needs; at the same time, it can also be built-in microcomputer chip, through programming control, to achieve full-color effects such as colorful gradient, jump, scan, and water; also The display screen of a certain specification can be replaced by the array and shape combination of multiple point light source pixels, and various patterns, text and animation, video effects, etc. can be changed; point light sources are extremely widely used in outdoor landscape lighting projects.
LED point light sources are very different from traditional heat radiation and gas discharge light sources (such as incandescent lamps, high-pressure sodium lamps).
The current LED point light sources have the following advantages in lighting:
1. good seismic and impact resistance
The basic structure of LED point light source is to place the electroluminescent semiconductor material on the lead frame, and then seal it with epoxy resin around it. There is no glass shell in the structure. There is no need to vacuum or fill a specific gas in the tube like incandescent or fluorescent lamps. Therefore, the LED light source has good shock resistance and impact resistance, which brings convenience to the production, transportation and use of the LED light source.
2. safe and stable
LED point light source can be driven by low voltage DC. Under normal circumstances, the power supply voltage is between 6 and 24 volts, and the safety performance is better. It is especially suitable for use in public places. In addition, in a better external environment, the light source has less light attenuation than traditional light sources and has a long life. Even if it is frequently turned on and off, its lifespan will not be affected.
3. good environmental performance
Because the LED point light source does not add metal mercury during the production process, it will not cause mercury pollution after it is discarded, and its waste can be recycled, saving resources and protecting the environment.
4. fast response time
The response time of incandescent lamps is milliseconds, and the response time of lighting is nanoseconds. Therefore, it has been widely used in the fields of traffic lights and car lights.
5. good brightness adjustment
According to the principle of LED point light source, the luminous brightness or output flux is positively changed from the current basic. Its working current can be large or small within the rated range, and has good adjustability, which lays the foundation for realizing user-satisfied lighting and brightness stepless control of LED point light sources.
