LED Light-emitting Diodes' Performance Fundamentals-Zhuhai Optoelectronics Technology Co., Ltd.

At present, there are not many capabilities to produce LEDs and LED manufacturers. Different manufacturers choose different quality LEDs is an important reason for different LED lighting prices. Taking red LED as an example, the generally used ordinary red LED price is between 0.03-0.08 yuan, and the red LED price suitable for the production of LED lighting is between 0.12-0.36. The LED lighting tube LED lighting manufacturers are difficult to distinguish, not to mention consumers. Therefore, the products of the LED lighting factory that produced LED light -emitting diode or a complete LED detection device are more guaranteed to be more guaranteed. The fundamentals of LED performance are listed below. (1) Brightness: The brightness of the LED is different, the price is different. (2) Anti -static capability: LEDs with strong anti -static capacity, long life, so the price is high. Usually anti -static than 700V LED can be used for LED lighting. (3) Wavelength: LED with the same wavelength, the same color, the price is high. Manufacturers without LED spacing divisions can basically not produce pure color products. (4) Leakage current: LED is a unidirectional conductivity luminous body. If there is a reverse current, it is called LED with a large leakage current. (5) Lighting angle: different LEDs with different uses are different, special lighting angles, high prices. (6) Life: The key to different quality is life span, life span is determined by light decline. Light failure, long life, long life, high price. (7) The chip: the luminous body of the LED is a chip, different chips, the price is very different. The price of chips in Japan and the United States is relatively high. Generally, chips produced by Zhuhai and mainland China are lower than Japan and the United States. (8) The size of the chip: the size of the chip is expressed by the side length, the quality of the large chip LED is better than the small chip. Price is directly proportional to the size of the chip. (9) Collagen: The collagen of ordinary LEDs is generally epoxy resin, and the price of LEDs with anti -ultraviolet and fireproof agent is more expensive. High -quality outdoor LED lighting should resist ultraviolet rays and fire prevention.
