Continuous development of lighting industry, LED lighting and traditional lighting constant competition. Production of LED and LED lighting manufacturers numerous, different manufacturers use different quality LED lamps LED is caused by a different reason. Due to increasingly fierce price war, appearance, structure, function almost the same product, there are two to three times the price difference, many users get a moment to be faint mind, I do not know come from the spread, generally do not produce led street lights price LED light tube are difficult to distinguish, not to mention consumers.
So they have a good selection of LED sources of production, or testing equipment has improved LED LED lighting factory would be better, so buy LED lighting products will be more secure.
We take a look at what factors caused the price difference LED lamps:
1, Brightness
LED brightness is different, different prices.
2, antistatic ability
Antistatic ability of LED, long life, and therefore higher prices. The LED is usually static than 700V can be used for LED lighting.
3, the wavelength
Same wavelength LED, and color, such as requiring the same color, the price is high. No LED spectral separation device manufacturers is difficult to produce pure colors.
4, leakage current
LED is one-way conductive light, if there is reverse current is called leakage, leakage current is large LED, short life, low prices.
5, light angle
Different uses LED light emission angle is not the same. Special light-emitting angle, and higher prices. If all diffusion angle, higher prices.
6, life
Different quality is the key to life, life is determined by the light fades. Light decay, long life, long life, high price.
7, LED chips
LED luminous body for the chip, different chips, prices vary widely. Japan, the United States more expensive chips, Taiwan factory and China's domestic manufacturers of led street light supplier prices lower than Japan and the US.
8, the chip size
The size of the chip to side expressed great quality LED chip is better than small chips. Chip size is proportional to the price of the same.
9, colloids
LED ordinary colloidal generally epoxy resin, plus a UV LED and fire agents more expensive and high quality outdoor LED lighting should be UV and fire.
LED lighting market is still part of the outlaws, cheating suppliers, suppliers of material fraud finished products to finished abnormally low prices in exchange for cash. There are a few LED lighting manufacturers to deceive unrealistic promises dealers and users, and then continue to change the firm or person in charge of trick to shirk responsibility, therefore, when consumers buy must pay attention to these details.
