At present, LED lighting plays an important role in all walks of life, but the light decay of LED is a headache for every lighting company. How to ensure that the luminous decay of LED light source is less than% during the year? How to solve the problem of LED explosion-proof lamp decay? Your answer: LED thermal management technology includes thermal management of chips, packaging and system integration. In terms of chips, lighting factories strive to improve the crystalline quality of materials or design new structures to improve the internal and external quantum efficiency of the chip itself, which has lower thermal resistance than traditional low thermal conductivity sapphire substrate chips. For the LED explosion-proof lamp, it mainly aims at the heat dissipation method of the lamp, and improves the heat transfer power-the work of the heat dissipation design. The LED quality problem: the LED chip used is of poor physical quality and the brightness decays quickly. Use conditions: the thermal resistance of the LED chip itself, the influence of silver glue, the heat dissipation effect of the substrate, and the glue and gold wire are also related to light decay. Therefore, it is necessary to ensure a minimum LED light decay, reasonable lamps and high-quality chips are the best choice for long-life lighting.
