Several reasons for the different prices of LED explosion-proof lamps

QQ Telephone East China Zhou Wenbiao //.ohzmdj.com/ There are many manufacturers of LED and LED lighting. Different manufacturers choose different quality LEDs which is an important reason for the different prices of LED lighting. Due to the increasingly fierce price war, products with almost the same appearance, structure, and functions have a price difference of one-fold. Many users are confused for a while and do not know where the price difference comes from. Generally, LED lighting manufacturers that do not produce LED light-emitting tubes are very common. Difficult to distinguish, let alone consumers.

Let's take a look at what factors cause the price difference of LED lamps:

, brightness

The brightness of the LED is different and the price is different.

、Antistatic ability

LEDs with strong antistatic ability have long life and high price. Generally, only LEDs with antistatic properties greater than V can be used for LED lighting.

、Life

The key to different qualities is life, and life is determined by light decay. Low light decay, long life, long life, high price.

、LED chip

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.

, chip size

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.

, colloid

The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-ultraviolet and fire retardants are more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof.

, wavelength

LEDs with the same 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.

、Leakage current

LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.

、Lighting angle

LEDs with different purposes have different light-emitting angles. Special light-emitting angle, higher price. Such as full diffusion angle, the price is higher.
