LED light source features

Lumen, long life, long life, high price. LED light-emitting LED chip, the chip body, different chips, prices vary widely. Japan, the United States more expensive chips, the Taiwan factory with local manufacturers LED chip prices lower than Japan and the U.S.. Market Analysis: LED lamps cost about what the main factors? The size of the chip size of the chip to the side of that great quality of LED chips are better than small chips. Price proportional with the chip size. LED ordinary colloidal gel is generally epoxy resin, plus a UV LED and fire agents more expensive, high quality outdoor LED lighting should be UV and fire. Brightness LED brightness different from the price difference. LED LED lamps for laser level should be consistent with class Ⅰ criteria. Antistatic ability of the LED, long life, and therefore higher prices. The LED is usually static than 700V can be used for LED lighting. The same wavelength wavelength LED, and color, such as requiring the same color, the price is high. No LED spectral separation device manufacturer of products difficult to produce pure colors. Leakage current of LED is one-way conductive light, if there is reverse current is called leakage, leakage current is large LED, short life, low prices. Use a different angle LED light emitting angle is not the same. Special light-emitting angle, and higher prices. Such as full diffuse angle, higher prices
