1.LED high mast light cost, LED light source chip cost accounted for about 37%,led package accounted for 24%, sales cost 15%, lamp housing ratio of 2%, lamp pole 2%. 1, led high pole lamp brightness is different, the price is different.
2, anti-static strong high mast light source, long life, thus high prices. Usually the antistatic light is greater than 700V for the LED high pole lamp.
3, the wavelength of the same led light source, the price is high. No LED color separation instrument manufacturers it is difficult to produce pure colors of products.
4, leakage current LED is a one-way conductive light-emitting body, if there is a reverse current, called leakage, leakage current large LED, short life, low price.
5, LED high pole lamp with cast light lamp luminous angle is different. Special luminous angle, high price. such as full diffuse angle, the price is higher.
6, life is different. The key to quality is life, life is determined by light decay. Light decay small, long life, long life, high price.
7, LED high mast lighting light-emitting body for chips, different chips, prices vary greatly. Japan, the United States, the chip is more expensive, Taiwan and China’s local manufacturers of LED chip prices lower than the day, the United States.
8, chip size of the size of the chip to length, large chip led quality is better than small chip. The price is proportional to the size of the chip.
9, ordinary LED street lamp colloid generally for epoxy resin, plus anti-ultraviolet and fire retardant led price more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire protection.
