Improve thermal performance led tube lights components A third
We disassembled wide range of led tube lights products . In chips, LCD panels, a variety of electronic components in a configuration , and many other things to watch , so I feel " is really a lot of efforts ," the place is cooling measures . Use heat pipe , heat sinks, hot plate , so that part is easy to heat releasing heat , the methods used for each product has its own characteristics , reflecting the developer's design ideas.
Now, there is a material companies are trying to increase the cooling measures in these new methods , this enterprise is the development of ceramic materials Nishimura pottery industry . The company plans to promote the use of cooling measures are ceramic circuit board thermal emissivity .
Cooling measures consultants , Thermal Design Laboratory Representative Director Naoki summit , said heat mode of transmission of the " thermal conductivity ", " convection ", " heat radiation" three forms , the lattice vibrations spread the movement of free electrons in the metal are " heat conduction , " heat transfer fluid motion are" convection ", through the heat wave is " thermal radiation . " Nishimura pottery industry development approach is the use of infrared radiation ceramic materials for heat dissipation .
Thermal radiation cooling method has the advantage that the casing closed and very thin , heat can not be transferred by convection cases, releasing heat . Some technicians have long known this advantage , but very few take advantage of precedent . However, according to Nishimura pottery industry introduced recently by thermal radiation heat of led lighting products has increased. Among them, Japan, a lighting enterprise from its application to other large emitter LED lighting lamps and other small led tube lights products to a variety of uses.
By using thermal radiation cooling, can improve the efficiency of the emitter of heat , eliminating the need for cooling fans. Do not use the cooling fan can reduce the risk of failure ( fan paralyzed due to the occurrence of a failure , preventing the risk of heat ) , and, because no more flaky fins , so no dust , eliminating the hassle of cleaning . In the manufacture of stands , through the use of thermal radiation cooling , the successful implementation of the light source near the shell slim design .
It is a deep interest in , whether it is large product , or small products, Nishimura pottery industry enterprises to provide lighting ceramic circuit board is basically the same . Ceramic circuit boards of the width of 30mm, length 55mm × horizontal long hexagon , a thickness of about 6mm , screw the multi- chip-type LED module fixed to the circuit board using . The maximum available power of 19W high power led tube lights modules . Large product LED modules using multiple screws fixing the ceramic circuit board using a small product . Ceramic circuit board material using an alumina purity of 99.7% , heat radiation rate of 0.97 . Smooth surface , the average roughness of 0.5μm, directly screw the LED module fixed to the circuit board surface .
The metal circuit boards and printed circuit board compared to ceramic circuit board is the high cost of the obstacles faced . However , if we can help ceramic circuit board to improve mass production of generic effects, it could somehow curb rising costs . This requires increased production number , but so far , mass production has not yet commenced business because of the high cost ceramic circuit board feel fear .
To address this situation , Nishimura pottery industry that the use of ceramic circuit board, used to install LED module circuit board and heat sink cooling can reduce the total cost of components , cooling costs in the future in such a plan as a selling point to advertise. The company is so confident, because of the introduction of the company 's lighting products enterprise in comparison with ceramic circuit board products and traditional thermal design of products , and to consider the total costs , without exception, chose ceramic circuit board . For compressed whether the popularity of the idea of the total cost , I will pay close attention to the future . Perhaps , you can shape led tube lights simple to predict whether the increased degree of popularity .
