Detailed Product Description: | Power led belong sensitive components, cooling and reliability are the main factors affecting the high-power LED applications, while using the 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, especially in high-power LED lamp beads, because of its high power, about 60% of the energy will be converted to heat energy released (As semiconductor technology development, photoelectric conversion efficiency will gradually increase), which requires the end-user in the application of high-power LED product when advertising light boxes lights, heat work to do to ensure high power LED products work properly. 1. Heat sink requirements. Shape and material: do not ask if the finished seal can occur directly with the outside air convection environment side lights Light Box, 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, the total surface area to dissipate heat effectively ≥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 box lights, 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) Raab box lights, thermal grease applied evenly requirement, the amount and then screw fixation nip. The company strongly recommends that customers use high-pressure direct 220V light shutter, a plurality of series did not drop wiring, 24V shutter lights, shutter lights (dedicated to Raab boxes, plastic boxes, printing boxes, outdoor light boxes). 220V power side LED lights, high-power side-emitting light bar (dedicated to rolling light boxes, for surface light boxes, bus shelters light boxes, residential light boxes billboards led lights, high beam lighting (online consultation), light boxes lights from far lighting Technology Limited. Far Lighting Technology Co., Ltd. (www.ygzmkj.com) (www.ygzmkj.com) Shandong Dezhou, advertising lighting leader, over the years, the company is implementing the scientific management, innovation and development, honesty and trustworthiness policy, and satisfy customer needs. In the far lighting leadership with the staff warmly welcome all inquiries negotiations to create a far better future lighting. |
