As there are more and more LED lamp manufacturers on the market, there are not many manufacturers with safety certification and national product certification. How to choose some good-quality LED lighting products has become a headache for consumers. Here, I will teach you how to choose LED lighting products. The following LED candle light manufacturers introduce the basic performance of several LEDs: 1. Brightness LEDs have different brightness and different prices. The LED used for LED lamps should meet the laser class I standard. 2. Anti-static ability LEDs with strong anti-static ability have a long life and are therefore expensive. Generally, LEDs with anti-static voltage greater than 700V can be used for LED lighting. 3. LEDs with the same wavelength and wavelength have the same color. If the color is required to be the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors. 4. Leakage current LED is a unidirectional conductive light-emitting body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price. 5. LEDs with different light-emitting angles have different light-emitting angles. Special lighting angle, higher price. Such as full diffusion angle, the price is higher. 6. The key to different qualities of life span is life span, which is determined by light attenuation. Low light decay, long life, long life, high price. 7. Chip LED's light-emitting body is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive. Generally, the prices of chips from Taiwan and China are lower than those in Japan and the United States. 8.3 Chip size The size of a chip is expressed in terms of side length, and the quality of a large chip LED is better than that of a small chip. The price is proportional to the size of the chip. 9. Colloid The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-ultraviolet and fire retardants are more expensive, and high-quality outdoor LED lighting should be anti-ultraviolet and fireproof. Each product will have a different design, 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 safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant national standards. As LED is a new product, China's national standards are lagging behind, but the country provides product qualification tests. The price of LED lighting with safety certification (such as GS, CE, UL, etc.) and national product quality certification is higher because these products are reliable in safety design. Consumers should pay attention to the authenticity of the certificate. In terms of health, the price of products designed with non-toxic materials is higher, especially for indoor LED energy-saving lamps. Don’t be greedy for cheap LED lamps with peculiar smell. At present, only a few LED manufacturers use non-toxic materials to produce. The method can be separated directly by the nose, and the price of smelly products is much lower than that of odorless products. Toxins such as lead, mercury, and cadmium need to be analyzed by professionals. From the perspective of applicable environmental safety, there are reliable dust-proof and moisture-proof design, and the price of LED products that are fire-resistant, anti-ultraviolet, and anti-cracking at low temperatures are high.
