Reasons for the price gap of LED fluorescent lamps in Shenzhen
The LED lighting industry is developing rapidly, and there are many different kinds of lamps and lanterns, and the price difference is quite obvious. There are many manufacturers producing LEDs and LED lighting. Different manufacturers choose LEDs of different quality is an important reason for the differences in LED lamps. Due to the increasingly fierce price war of LED fluorescent lamps, products with almost the same appearance, structure and function have a price difference of 2-3 times. Many users are confused for a while and do not know where the price difference comes from. Generally, LED fluorescent tubes are not produced. It is difficult for lighting manufacturers to distinguish, let alone consumers. Let's take a look at what factors cause the price difference of LED lamps: the key factors that make the price of LED fluorescent lamps unpredictable. It is better to choose an LED lighting factory that has a good source of LED fluorescent lamp production, or has a complete LED testing equipment, so that the LED lighting products you buy will be more secure. The brightness of the LED is different, and the price is different. The lumen value or MCD determines the LED with strong antistatic ability, which has a long life and high price. Generally, LEDs with anti-static voltage greater than 700V can be used for LED lighting. At present, LEDs with the same wavelength that reach 1000V 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. LEDs are unidirectional conductive luminous bodies. If there is a reverse current, it is called leakage. LEDs with large leakage currents have short life and low prices. LEDs with different purposes have different light-emitting angles. Special lighting angle, higher price. Such as full diffusion angle, the price is higher. Generally, the key to sufficient different quality at 120 degrees is the life span, which is determined by the light attenuation. Low light decay, long life and high price. Generally, it reaches 50000H, and the luminous body of the LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive, while the prices of LED chips from Taiwanese and Chinese manufacturers are lower than those in Japan and the United States. Big chips are more expensive. The size of the chip is expressed by the side length, and the quality of the large chip LED is better than that of the small chip. The price is proportional to the size of the chip. The colloid of ordinary LEDs is generally epoxy resin, and LEDs with anti-ultraviolet and fire retardants are more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. Imported glue is of good quality, but the price is expensive, LED lamp beads are expensive.
