1, LED brightness (MCD) is different, the price is different. LEDs for LED lamps shall conform to the Ⅰ class standard for laser grade.
2, antistatic ability of strong anti-static led, long life, and thus high prices. Usually antistatic is greater than
700V led can be used for LED lighting.
3, consistent wavelength of the LED, color consistent, such as the requirements of the same color, the price is high. It is difficult for producers without led split-light separations to produce pure color products.
4, leakage current LED is one-way conductive light-emitting body, if there is reverse current, it is called leakage, leakage current large LED, short life, low price.
5, luminous angle uses different led its luminous angle is not the same. The special luminous angle, the price is higher. such as full diffuse angle, the price is higher.
6, the key to different quality of life is the life, the life of the decision by the light failure. Light decay small, long life, long life, high price.
7, the light-emitting of the chip LED is the chip, the different chip, the price difference is very big. Japan, the United States, the chip is more expensive, generally Taiwan and domestic chip prices lower than Japan, the United States (CREE).
8, the size of the wafer size to length said that the quality of large-chip led better than the small chip. The price is proportional to the size of the wafer.
9, colloidal ordinary led colloid generally epoxy resin, with anti-ultraviolet and fire-retardant led price more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire-resistant. Each product will have a different design, different design applicable to different uses, LED lighting reliability design includes: Electrical Safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use time and other factors. From the point of view of electrical safety, it should conform to the relevant international and national standards.
