First, LED light source: must use high-brightness, high-efficiency, low-light-loss LED chip package, which is to choose branded chip makers such as US Puri / Taiwan Jingyuan / Taiwan Guanghong and other brands of regular channel chip package led lamp Beads, package Gold wire / phosphor / insulating rubber, etc. are required to meet the required materials. Second, the driving power: led is a semiconductor component of DC electronic conversion light energy, so a stable driver needs to have a high-performance power driver chip, while the power factor pu compensation function is required to ensure power efficiency, the power supply to the entire lamp The important factors are related to the fact that the quality of led power supply on the market is uneven, and the good driving power supply not only ensures stable DC supply, but also fully guarantees the improvement of conversion efficiency. This parameter reflects the lamps. The true energy efficiency and no waste on the grid. Third, the appearance of the structure of the cooling system, an excellent lamp in addition to the appearance of high-end and generous, high-quality light source and power supply, but more important is the structural rationality of the shell, which involves the heat dissipation of led lamps, due to led conversion light energy At the same time, some of the electric energy is converted into heat energy, and it is necessary to dissipate the heat to the air, so as to ensure that the LED is stably lit, and the high temperature of the LED lamp will cause the light decay to be accelerated, which has an impact on the life of the LED lamp. It is worth mentioning that the technology of LED chip is continuously improved, the conversion efficiency is also improved, the energy consumption of heat conversion will be less, the heat sink parts will be used thinner, and the cost will be reduced, which is beneficial to the promotion of led, but This is just a technical development direction. At present, the heat dissipation of the outer casing is still a key factor to be investigated. Fourth, the lens of the LED lamp is often ignored by some designers. In fact, the refraction of light will cause light loss. The lens ratio of the lens also profoundly affects the luminous flux of the final output. At present, the lens with better transmittance can reach 93 or more. Because the lens is also a relatively important cost, some factories in order to save costs, some cheap lens materials are definitely secondary materials, the light transmittance is about 70, and the naked eye will not be able to see the consumer, but its practical instrument It is easy to test the results, the lens with poor material, and the long-term yellowing and other bad results.
