The lighting industry continues to develop, and LED lamps continue to compete with traditional lamps. There are many manufacturers of LED and LED lighting. Different manufacturers use different quality LEDs, which are the important reasons for LED lamps. Due to the increasingly fierce price war, the products with almost the same appearance, structure and function have a price difference of 2-3 times. Many users have been stunned for a while, and they do not know where the price difference comes from. Generally, LED lighting manufacturers that do not produce LED lighting tubes are generally not produced. It's hard to distinguish, let alone consumers. Therefore, it is better to choose a LED lighting factory that has a good LED production source or a complete LED testing equipment, so that the bought LED lighting products will be more secure. Let's take a look at what factors cause the price difference of LED lamps: 1. Brightness LEDs have different brightness and different prices. 2, anti-static ability Anti-static ability of the LED, long life, and therefore high price. LEDs with an antistatic greater than 700V are usually used for LED lighting. 3. LEDs with the same wavelength and wavelength? Consistent color, as required? The color is the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products. 4. Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, and LED with large leakage current has short life and low price. 5. LEDs with different illumination angles have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher. 6. The key to different quality of life is life, and life is determined by light decay. Low light decay, long life, long life and high price. 7, LED chip LED illuminator is a chip, different chips, the price difference is very large. The chips in Japan and the United States are more expensive, and the price of LED chips from Taiwanese and Chinese manufacturers is lower than that of Japan and the United States. 8, chip size The size of the chip is expressed by the side length, the quality of the large chip LED is better than the small chip. The price is proportional to the chip size. 9, colloidal ordinary LED colloid is generally epoxy resin, LED with anti-ultraviolet and fire retardant is more expensive, high-quality outdoor LED lighting should be resistant to UV and fire. There are still some illegal people in the LED lighting market, deceiving suppliers, defrauding suppliers of materials to produce finished products, and selling finished products at abnormally low prices in exchange for cash. There are also a few LED lighting manufacturers that use unrealistic promises to defraud dealers and users, and then use the tactics of constantly changing the firm or the person in charge to shirk responsibility. Therefore, consumers must pay attention to these details when purchasing.
