The LED lamp bead market is rising and mixed. How to choose a good LED lamp bead product has become a major problem faced by consumers. In the face of such a market, we must keep calm and calm. With the market, as consumers, the use of LED lamp beads should still be calm, scientifically analyzed, and choose the best cost -effective light sources and lamps. The basic performance of several LEDs is introduced below: 1. The brightness of LED lamp beads is bright. Different, the price is different. LEDs used for LED lamps should meet the laser level standard. 2. LED lamp beads with strong anti -static capabilities with resistance and static capabilities have long life, so the price is high. Usually anti -static than 700V LED can be used for LED lighting. 3. LED lamp beads with the same wavelength wavelength, the colors are consistent, if the color is required, the price is high. It is difficult for manufacturers without LED split -to -chromatography to produce pure color products. 4. Leakage current LED lamp bead is a unidirectional conductivity luminous body. If there is a reverse current, it is called leakage, LED lamp beads with large leakage current, short life, low price, low price. 5. LED lamp beads with different lighting angles are different. Special lighting angle, high price. Such as a full -firing angle, the price is high. 6. The key to different quality of life is life span, life span is determined by light decision. Light failure, long life, long life, high price. 7. The luminous body of the chip LED is a chip, different chips, the price is very different. Japan and the United States have more expensive chips. Generally, the price of Zhuhai and domestic chips is lower than that of Japan and the United States. 8. The size of the chip size chip is represented by the side length, the quality of the large chip LED lamp beads is better than the small chip. Price is directly proportional to the size of the chip. 9. The colloid of the ordinary LED lamp beads of the colloid is generally epoxy resin, and the price of LED lamp beads with anti -ultraviolet and fireproof agent is more expensive. Each product will have different designs, and different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use time and other factors. From the perspective of electrical safety, it should meet the relevant international and national standards.
