What factors caused the price difference of LED lamps

From: www.szbako.com Data:06/08/2016

we look at what factors caused the price difference of LED lamps:


1, brightness LED
brightness is different, the price is different.

2, antistatic ability
antistatic ability of LED, long life, and thus the price is high. Usually more than 700V anti-static LED can be used for LED lighting.

3, the wavelength of the
wavelength of the same 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, leakage current LED
is one of the unidirectional conduction of light emitting body, if there is a reverse current, it is called the leakage current, the leakage current of LED, short life, low price.

5, light emitting point of view
uses different LED light emitting angle is not the same. Special lighting angle, higher price. Such as the diffusion angle, higher prices.

6, life of
of different quality is the key to life, life is decided by the light fades. A small decline, long service life, long service life, high price.

LED decay is refers to the LED after a period of time after the light, the intensity will be lower than the original intensity, and lower part is the LED brightness. General LED packaging manufacturers to do the test in laboratory conditions (25 DEG C under normal temperature), to 20mA DC continuous light LED1000 hours to before and after the comparison of the light intensity.

7, LED chip
LED luminous body for the chip, chip of different, the price difference is very great. Japan, the United States more expensive chips, Taiwan factory and the Chinese local manufacturers LED chip prices lower than the day, the United states.

8, chip size, 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, colloidal

in the face of this time, the performance of a large gap,
10 factory process
