1, brightness LED brightness is different, the price is different. LED for LED lamps should meet the laser class Ⅰ standard.
2, anti-static ability Antistatic ability LED, long life, and thus high prices. Usually anti-static greater than 700V LED can be used for LED lighting.
3, the wavelength wavelength consistent LED light bar, the same color, such as the requirements of the same color, the price is high. Producers who do not have LED spectrophotograms are hard to produce purely color products.
4, leakage current LED is a one-way conductive light, if there is reverse current, known as leakage, leakage current LED, short life, low prices.
5, the use of different angles LED light angle is not the same. Special light angle, the price is higher. Such as full diffuse angle, the price is higher.
6, the quality of life is the key to the quality of life, life by the decay of light. Light fades small, long life, long life, high prices.
7, chip LED light for the chip, different chips, the price difference is very large. Japan, the United States more expensive chips, the general Taiwan and domestic chip prices lower than Japan and the United States.
8, the size of the chip chip size to side length, large chip LED quality is better than the small chip. The price is proportional to the chip size.
9, colloidal colloidal LED colloid is generally an epoxy resin, plus anti-ultraviolet and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire.
Each product will have a different design, different designs for different purposes, LED lighting reliability design includes: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, safe use of time and other factors. From the electrical safety point of view, should be consistent with the relevant international and national standards. As the LED is a new product, China's national standards lag, but the state to provide product testing. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certificate of LED lighting prices to high, because these products are safe in the design is reliable. Consumers pay attention to is to seriously identify the authenticity of the certificate, there are international safety certification and national product certification manufacturers are not many.
From the health, the use of non-toxic materials designed to high prices, especially indoor LED lighting, do not choose cheap odorous LED lighting, at present only a few LED manufacturers are non-toxic materials production, identify the method Can be directly with the nose, the smell of the product is much lower than the odorless price. Similar to lead, mercury, cadmium and other toxins need professional analysis. From the application of environmental safety, there is a reliable dust and moisture-proof design, materials, fire, anti-ultraviolet, anti-low temperature cracking of LED products, high prices.
