LED lamps Needle type radiator
1. The cylindrical radiator can be manufactured by die casting, while the needle radiator is manufactured by post-processing aluminum profiles. Although the processing methods of the two radiators are different, the heat dissipation path is almost the same. With decentralized heat dissipation, heat can quickly reach the heat sink through the shortest path for heat dissipation.

2. When the integrated light source is used as the light source of the downlight, because the size of the integrated light source is more concentrated than the entire downlight, the heat should be taken out in time to avoid heat when designing the radiator structure of the led lamp. Excessive collection and then conduct heat to the heat sink for heat dissipation.
3. The heat of the integrated light source is first conducted to the solid column in the center of the radiator, and then to the radiator via the solid column
4. There is a spot on the light-emitting surface of the led luminaire, which usually requires a relatively large distance from the integrated light source to the light-emitting surface, which requires a higher reflector height. Therefore, the height of the led luminaire using the integrated light source will be higher, and the volume of the entire luminaire is natural Big.
Using high-power LEDs as the light source of LED lamps is a compromise method that takes into account the advantages and disadvantages of low-power LEDs and integrated light source LEDs. In fact, in the design of LED lamps, it is not certain which lamp bead is used as the light source of LED lamps. It is necessary to comprehensively consider the overall performance and cost and make a comprehensive analysis to determine which LED is most suitable.
