At present, there are only a few manufacturers capable of producing LED and LED lighting. Different high-brightness LED lamp bead manufacturers use different quality LEDs, which is an important reason for the different LED lighting prices. 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 good LED production source, or LED lighting with perfect LED testing equipment, so that the purchased LED lighting products will be more secure.
In-line LED lamp bead manufacturers take you to find out what factors cause the price difference of LED lamps:
1. The brightness of the brightness LED is different and the price is different. LEDs used in LED luminaires shall comply with the laser class I standard.
2. Antistatic ability??
LEDs with strong antistatic properties have a long life and are therefore expensive. LEDs with an antistatic greater than 700V are usually used for LED lighting.
3. LEDs with the same wavelength and wavelength have the same color. If the color is consistent, 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 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.
