Lighting High beam lights, light bar on the radio 2.5 meters, good effect, skill Radio and TV power led belong sensitive components, far shutter lamp lighting, cooling, and reliability are the main factors affecting the high-power LED applications, so When using high power led light source to pay attention to what the problem? Heat due to limitations of the semiconductor light-emitting diode chip technology, LED photoelectric conversion efficiency to be improved, Guangzhou far shutter lamp lighting, especially in high-power LED lamp beads, because of its high power, about 60% of electricity will become into heat release (with the development of semiconductor technology, photoelectric conversion efficiency will gradually increase), which requires the end-user in the application of high-power LED product, cooling work to do to ensure that high-power LED lamp bead product is working properly. 1. Heat sink requirements. Shape and material: do not ask if the finished seal, convection can occur directly with the outside air environment recommended with aluminum or copper fin heat sink. 2. Effective heat dissipation surface area: For 1W high power LED white (other colors basically the same) Some use the unit heat sink, Wuhan far illumination light shutter, the sum of effective heat dissipation surface area ≥50-60 square centimeters. Recommendations for 3W effective cooling fins sum ≥150 cm surface area, higher power, as the case and test results increase, try to ensure that the heat sink temperature does not exceed 60 ℃. 3. Connection method: When high power LED board and heat sink connection please ensure that the two contact surfaces smooth, good contact, in order to strengthen the degree of integration of the two contact surfaces is recommended in the bottom of the LED board or the heat sink surface is coated with a layer of thermal grease ( thermal grease thermal conductivity ≥3.0W / mk), the requirements of thermal grease applied evenly, the amount and then screw fixation nip. Beam lighting (Figure), Beijing shutter light beam illumination, shutter light beam illumination provided by the far-Lighting Co., Ltd. Far Lighting Technology Co., Ltd. (www.ygzmkj.com) (www.ygzmkj.com) located at No. 186 in Dezhou City, Shandong Province Xiajin Economic Development Zone Luan Road.
