However, LED lamp shell heat and the use of premises in accordance with the power level, there will be different options. Cooling methods are mainly the following: Al fin: This is the most common way of cooling, aluminum fins as part of the housing to increase the cooling area. Thermal plastic case: a thermally conductive material is filled in when Yidu led display production plastic injection molding, plastic housing increases thermal conductivity, heat capacity. Air hydrodynamics use light shell shape, creating a convection air, which is the lowest-cost way to enhance heat dissipation. Fan lights shell reinforced with long life and efficient internal cooling fan, low cost led display production, good results. But the trouble is that some fans want to change, does not apply to outdoor, this design is more rare. The use of heat pipe heat pipe technology, the heat conduction from the LED chip to the housing fins. In large lamps, such as street lights, etc. are common design. Surface radiation heat lamp shell surface treatment do radiation heat treatment, the simplest is to apply heat radiation Wei Sheng Zhi Hua paint Enshi professional led display production, radiant heat mode can be taken away from the surface of the lamp housing. The maximum brightness of the LCD display when the male led display production, usually determined by the cold cathode fluorescent tube (backlight), the luminance values ??are generally in the 200 ~ 250 cd / m2 room. LCD brightness is slightly lower, will feel the screen is dark. Through years of experience, and now brightness LCD monitors on the market generally are 250cd / m2, more than 24 inches of the display will have a slightly higher, but remain at 300 ~ 400 cd / m2 room, although it is technically possible to achieve higher brightness, but that does not mean that the brightness values ??higher the better, because the high brightness of the display is possible to make the viewer eye injury Yichang professional led display production _ Jinrui Guang electricity (certified) _led display production from Yichang Jinrui Guang Science and Technology Limited.
