1. Heat dissipation Due to the limitation of semiconductor light-emitting diode chip technology, the photoelectric conversion efficiency of light-emitting diodes still needs to be improved, especially high-power light-emitting diodes, due to their high power, causing a large part of the electrical energy to be converted into thermal energy (as semiconductor technology Development, photoelectric conversion efficiency is gradually improving), which requires end customers to do a good job of heat dissipation when applying high-power LED products to ensure that high-power LED products work normally.
2. Static electricity protection light-emitting diodes are semiconductor devices, which are more sensitive to static electricity, especially for white, green, blue, and purple light-emitting diodes to prevent static electricity and eliminate static electricity.Three, soldering points 1. When soldering, prefer a constant temperature soldering iron, the soldering temperature is below 260 ℃, the soldering iron and the light-emitting diode pad contact time does not exceed 3s. 2. For high-power LEDs encapsulated by silicone, the highest heat-resistant temperature of silicone is 180℃, so the soldering temperature of LEDs should not exceed 170℃. Use low-temperature soldering iron and low-temperature solder paste (wire) soldering, soldering iron and LED soldering The contact time of the disc does not exceed 3s.
4. Advantage analysis 1. Less power consumption: The light-emitting diode with a light efficiency of 75lm/w greatly reduces the power consumption of the incandescent lamp with the same brightness. 2. Long life: The product has a lifespan of up to 50,000 hours and can be continuously lit for 24 hours. 5 years 3. Nanosecond response speed makes the dynamic control of brightness and color simple: dynamic color change and digital control can be realized 4. Large design space: integration with the building can be achieved, so that only the light can be seen without the light effect.5. Environmental protection: no harmful metal mercury, no infrared and ultraviolet radiation.6. Color: Different wavelengths produce different colored lights, bright and saturated, no filter is required, and can be controlled by the three primary colors of red, green and blue to form a variety of different colors, which can achieve various color changes such as full-color gradients.
