With rushing headlong into the market, as consumers, choose led still to be calm, scientific analysis, choose the price the best light sources and luminaires, here are the basic properties of several kinds of LED:
1, brightness LED brightness is different, the price is different. The LED used for LED lamps shall be in accordance with the laser grade class I standard.
2, antistatic ability of the LED, strong ability of the long life, and therefore the price is high. Usually more than 700V anti-static LED can be used for LED lighting.
3, the wavelength of the same wavelength of LED, the same color, such as the requirements of color, the price is high. No LED color device manufacturers are difficult to produce pure color products.
4, the leakage current LED is a one-way conductive light body, if there is a reverse current, it is called the leakage, the leakage current of LED, short life, low price.
5, the use of different light emitting point of view is not the same as the LED. Special lighting angle, higher price. Such as the diffusion angle, higher prices.
Key 6, life of different quality is life, life is decided by the light fades. A small decline, long service life, long service life, high price.
7, chip LED light emitting body for the chip, different chips, the price difference is great.
8, the chip size of the size of the chip to side said that the quality of chip LED chips is better than small. The price is proportional to the size of the chip.
9, the colloid of ordinary LED of the colloid is generally epoxy resin, with anti ultraviolet and fire retardant LED price is more expensive, high quality outdoor LED lighting should be anti ultraviolet and fire.
Each product will have different different design for different purposes and include the reliability of LED lighting designs: electrical safety, fire safety, the application of environmental security, safety of machinery, safety and health, safety use time and other factors. From an electrical safety point of view, should be consistent with the relevant international and national standards.
