Choose two-sided light boxes, led lighting power far side of the light lights, more power, more energy-efficient, easy to install, three-year warranty, light effect strong, double-sided light boxes, no dark areas. 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, Jiangsu double-sided light boxes, because of its high power, about 60% of electricity will be turned into heat release (with the development of semiconductor technology, Shandong double-sided light boxes, 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 beads the 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, the total surface area to dissipate heat effectively ≥50-60 square centimeters. Recommendations for 3W heatsink efficient heat dissipation surface area sum ≥150 cm, depending on the situation and increase the higher power test results, Zhejiang double-sided light boxes, 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.
