Third ways to improve the thermal performance of LED lighting components

Recently the use of thermal radiation cooling LED lighting products have increased. Among them, a lighting appliance companies in Japan will be applied to a variety of applications such as light from the projector and other large LED lighting appliances to small lamps. The cooling efficiency of the projector can be improved by adopting the heat radiation cooling, and the cooling fan can not be used again.

The advantage of heat radiation method is that it can release heat when the enclosure is closed and thin, and the heat can not be transferred by convection. Some of the technical staff have long known this advantage, but few have made full use of it. Recently the use of thermal radiation cooling LED lighting products have increased.

Among them, a lighting appliance companies in Japan will be applied to a variety of applications such as light from the projector and other large LED lighting appliances to small lamps. The cooling efficiency of the projector can be improved by adopting the heat radiation cooling, and the cooling fan can not be used again. Do not use the cooling fan can reduce the risk of failure (due to the occurrence of a fault and the risk of fan paralysis, lead to heat), and because no more like fins, so no dust, eliminating the trouble of cleaning.

Third ways to improve the thermal performance of LED lighting components

In the production of table lamp, through the use of thermal radiation heat dissipation, the successful implementation of the light source near the shell of ultra-thin design. Ceramic circuit board are long 55mm * wide 30mm of the long hexagon, thickness of 6mm or so, with screws to multi chip LED module fixed on the circuit board. High power LED module with maximum power of 19W.

The LED module is fixed on the ceramic circuit board with a plurality of screws, and the material of the 1 ceramic circuit boards is made of alumina with a purity of 99.7%, and the thermal radiation rate is about 0.97. The surface is smooth and the average roughness is 0.5 m, and the LED module is fixed on the surface of the circuit board by screws. Compared with the metal circuit board and printed circuit board, ceramic circuit board is facing a high cost. However, if we can use the ceramic circuit board to improve the mass production effect, we can curb the rise in costs to some extent. The need to increase the number of production, but as of now, mass production has not yet commenced, the reason is the high cost of enterprise of ceramic circuit board feel fear.
