There are currently capable of producing LED and LED lighting manufacturers also one of the few, different manufacturers use different quality LED lighting LED is causing the price of various important reasons. Due to increasingly fierce price war, appearance, structure, function almost the same product, there are 2-3 times the price difference, many users get faint moment is mind, I do not know come from the spread, generally do not produce LED lighting manufacturers 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 cause the price difference of LED lamps:
LED brightness, different prices. LED for LED lamps shall comply with the Laser Class Class Ⅰ standards.
2, antistatic ability
Antistatic ability of the LED, long life, and therefore higher prices. Typically the static than 700V LED can be used for LED lighting.
3, the wavelength
The same wavelength LED, consistent color, such as requiring the same color, the price is high. No LED spectral separation device manufacturers is difficult to produce pure colors.
4, the leakage current
LED is one-way conductive light, if there is a reverse current is called leakage, leakage current is large LED, short life, low prices.
5, light angle
Its different uses LED emitting angle is not the same. Special light-emitting angle, the higher the price. If all diffusion angle, the higher the price.
Quality is the key to a different life, life is determined by the light fades. Light decay, long life, long life, high price.
7, LED chips
LED light-emitting body is a chip, different chips, prices vary widely. Japan, the United States more expensive chips, Taiwan factory with Chinese local manufacturers of LED chip prices lower than Japan, the United States.
8, the chip size
The size of the chip to side expressed great quality LED chip is better than the small chip. Chip size is proportional to the price of the same.
Ordinary LED colloidal generally epoxy resin, plus a UV resistant and fire retardant in LED expensive, high-quality outdoor LED lighting should be UV and fire.
10, power supply
In LED lighting power play a very important role in stabilizing the power to complete the mature long-life LED lamps, and can adapt to various situations electricity grid, the greatest degree of protection LED lamp beads.
11, the structure and production process of lamps
Structure determines the possibility of thermal heat conduction process determines the reliability.
Not to light up for the purpose, is to use technical indicators standards
LED lighting market is still part of the outlaws, cheating suppliers to defraud suppliers produce finished materials to the finished product is not normal low prices for cash. There are a few LED lighting manufacturers to unrealistic promises to deceive dealers and users, and then keep changing firm or person in charge of trick to shirk responsibility.
