Led Street Light Housing Wholesale To Share Knowledge On Heat Dissipation Of Lamp Housing
Led Street Light Housing Wholesale the heat dissipation method of the projection lamp housing, which generally uses natural cooling, but the effect is not very obvious, and there is no obvious heat index. With the continuous development of technology, we are now slowly relying on led projection lamps The technical means of the casing itself solves its own heat dissipation problem.1. High brightness led heat.The heat is concentrated in a small chip size, the temperature of the chip, the thermal stress and the power generation efficiency and efficiency of the phosphor light emitting chip are reduced. When the temperature exceeds a certain value and the distribution is uneven, the equipment failure rate increases exponentially. Statistics show that increasing the temperature of the equipment by 2 ° C reduces the reliability by 10%. If there is more than one white light LED backlight system, including the dense heat dissipation problem is more serious. Solve the application requirements of high-brightness LED thermal management.2. The relationship between chip size and heat.In order to improve the LED floodlight housing manufacturers, the direct way to increase the input power, and in order to prevent saturation in the PN junction active layer, must increase the size accordingly, with a higher transition temperature related power increase, thereby making quantum efficiency. The increase in power of a single tube depends on the heat capacity of the device coming from the chip material, maintaining the existing structure, during the construction process, a constant current density on the chip and the equivalent thermal conditions, the scale of the single chip to increase the transition temperature will rise PN junction.The above content is organized and shared by China Aluminum Die-cast LED Street Light Housing Suppliers , hoping to help those in need.
