Nine ways to help you with the selection of qualified LED light source

　　As a consumer, use LED lighting needs to be calm, scientific analysis, the choice of the best cost-effective light sources and lamps, here are a few basic properties:

　　1, Brightness: Different LED brightness has different prices. LED lamps shall comply with Laser ClassⅠ standards.

　　2, Antistatic ability: antistatic ability of the LED, long life, and therefore higher prices. Usually static than 700V of the LED can be used for LED lighting

　　3, Wavelength: the same wavelength of the LED, the same color, such as requiring the same color, then the price is high. No LED spectral separation device manufacturers is difficult to produce pure colors.

　　4, Leakage current: LED is unidirectional conductive light, if there is reverse current is called leakage, leakage current is large LED, life is short, low prices.

　　5, Beam Angle: LED light source uses a different angle is not the same as its luminous. Special light-emitting angle, and higher prices. If all diffusion angle, higher prices.

　　6, Lifespan: different qualities is the key to lifespan, LED lamp life determined by the light fades. Light decay, long life, long life, high price.

　　7, Chip: LED light-emitting body is chip, different chips, prices vary widely. Japan, the United States more expensive chips, in Taiwan and chip prices lower than Japan and the U.S.

　　8, Chip size: The size of the wafer to the side that big chip LED chip quality is better than small. Chip size is proportional to the price of the same.

　　9, Colloidal: ordinary LED colloidal generally epoxy resin, plus a UV LED and fire agents more expensive, high-quality outdoor LED lighting should be UV and fire. Each product will have a different design, different designs for different purposes.
