Guangmai Technology is professional in making the White SMD Light Emitting Diode Chip 3 Watt 3535 Package.
SMD Light emitting diodes application:
The rapid progress of LED technology in the 1990s not only exceeded the luminous efficiency of incandescent lamps, and the light intensity reached the candlelight level, but the colors also covered the entire visible spectrum from red to blue. This technological revolution from indicator level to beyond the level of general light sources has led to a variety of new applications, such as car signal lights, traffic lights, large outdoor full-color display screens, and special lighting sources.
With the development of high-brightness and multi-color light-emitting diodes, the application field is also expanding. From the lower luminous flux indicator to the display screen, and then from the outdoor display to the medium luminous flux power signal lamp and the white light source for special lighting, finally Developed to the upper right corner of the high luminous flux general lighting source. The year 2000 is the dividing line of time. In 2000, the signal display problems and lighting problems of all colors have been solved, and special lighting applications with low and medium luminous fluxes have begun. However, as general lighting applications for high luminous flux white light lighting, it seems that there is still time. In Japan, the luminous flux needs to be further increased significantly before it can be realized. Of course, this is also a process, which will be gradually realized as the brightness increases and the price decreases.
Heat dissipation of light-emitting diode package
In semiconductor lighting devices, high-power and high-brightness light-emitting diodes (LEDs) are usually used as light sources. When current is passed through the light-emitting diodes, electrons and holes will directly recombine to release energy and emit light. The advantages of long service life, etc., are widely used in the field of lighting. However, the current photoelectric conversion efficiency is low, and a large proportion is converted into heat energy, so the power density on the LED chip is high. The high power density also puts forward high requirements on the heat dissipation of the device, and the heat dissipation problem of the package in the light emitting diode has become a major problem affecting its industrial development.
Light-emitting diode Cooling method
The heat dissipation mechanism of LED generally has the following forms:
1. The use of thermally conductive metal or heat dissipation fins and the LED package to attach heat dissipation.
2. Install a fan to force heat dissipation.
3. A circulating liquid is provided in the package to dissipate heat.
4. The combination of the heat pipe in the package can absorb or dissipate heat energy when the working medium in the heat pipe changes phase.
