There are currently capable of producing LED and LED lighting is also one of the few manufacturers, different manufacturers use different quality LED lighting LED is caused by an important reason for different prices. As the increasingly fierce price war, appearance, structure, function almost the same product, there are 2-3 times the price difference, many users get unconscious mind is one o'clock, I do not know come from the spread, generally does not produce LED light tube LED lighting manufacturers are difficult to distinguish, let alone consumers.
Therefore, they have a good selection of LED sources of production, or testing equipment has improved LED LED Lighting Factory would be better, so that LED lighting products purchased will be more secure.
What are the factors we look at the price differences caused by LED lamps:
1, the brightness
LED brightness is different from the price difference. LED LED lamps for laser level should be consistent with class Ⅰ criteria.
2, anti-static capability
Antistatic ability of the LED, long life, and therefore higher prices. The LED is usually static than 700V can be used for LED lighting.
3, the wavelength
The same 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.
4, the 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 emitting angles
LED uses different point of view of their different light. Special light-emitting angle, and higher prices. If all diffusion angle, and higher prices.
6, the life
Different quality is the key to life, life determined by the light failure. Lumen, long life, long life, high price.
7, LED chip
LED's light for the chip, 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..
8, the chip size
The size of the chip to the side of that great quality LED chips are better than small chips. Price proportional with the chip size.
9, colloidal
LED ordinary colloidal usually epoxy resin, plus a UV LED and fire agents more expensive, high quality outdoor LED lighting should be UV and fire.
10, power supply
LED lighting power supply has played a very important role in stabilizing the power to complete the mature long-life LED lamps, and can adapt to a variety of power-line conditions, the maximum degree of protection LED lamp beads.
11, lighting the structure and production technology
Structure determines the possibility of heat, heat the reliability of the decision process.
12, sense of responsibility
Not to light up for the purpose of standard production specification is
LED lighting market is still part of the outlaws, cheating suppliers, materials, finished products supplier fraud to sell low-priced products is not normal for cash. A small number of LED lighting manufacturers to unrealistic promises deceive dealers and users, and then continue to change the firm or person in charge of the trick to pass the buck
