1. LED light source: LED chip packaging with high brightness, high luminous efficiency and low light decay must be used. This requires the selection of LED lamp beads packaged by brand chip manufacturers such as American Purui/Taiwan Jingyuan/Taiwan Guanghong and other brands of regular channel chips. The gold wire/phosphor/insulating glue, etc., all need to use materials that meet the requirements.
2. Drive power supply: LED is a semiconductor component that converts DC electrons into light energy, so a stable drive requires a high-performance power supply driver chip, and at the same time requires the function of power factor pu compensation to ensure power supply efficiency. The most important factor is that the quality of the LED power supply on the market is uneven, and the quality of the LED power supply is mixed. A good driving power supply not only ensures a stable DC supply, but also fully ensures the improvement of the conversion efficiency. This parameter reflects the lamps and lanterns. The real energy saving and no waste to the grid.
3. A heat dissipation system with a compact appearance structure, in addition to a high-end and generous appearance, high-quality light source and power supply, an excellent lamp is more important is the structural rationality of the shell, which involves the heat dissipation of LED lamps, because LEDs convert light energy. At the same time, a part of the electric energy is also converted into heat energy, and the heat needs to be extracted and dissipated into the air, so as to ensure the stable lighting of the LED. It is worth mentioning that the technology of LED chips is constantly improving, and the conversion efficiency is also improved. The power consumption of heat conversion will be less, and the heat sink components will be thinner, which will also reduce costs due to some, which is conducive to the promotion of LEDs, but This is just a technical development direction. At present, the heat dissipation of the casing is still a parameter that must be investigated.
4. The lens of the LED lamp is often ignored by some designers. In fact, the refraction of light will cause light loss, and the lens rate of the lens also profoundly affects the final output luminous flux. At present, the lens with better light transmittance can reach more than 93 , Since the lens is also a relatively important cost, some factories use cheap lens materials in order to save costs. It must be a secondary material. The light transmittance is about 70. It will not be obvious to the naked eye to deceive consumers, but it is practical. It is easy to test the results. Lenses with poor materials will turn yellow and other bad results after a long time.
