subject: Led Lighting Price "mystery" Mystery Factor For You [print this page] Continuous development of the lighting industry, LED lamps and constant competition with traditional lamps. Manufacturers of LED lighting and LED a large number of production, different manufacturers use different quality of LED is the LED lamps and lanterns of different important reasons. Due to the increasingly fierce price war, appearance, structure, and function is almost the same as product, price difference is 2-3 times, many users get unconscious mind for the moment, I do not know price differences come from, generally does not produce LED lighting of LED luminotron manufacturers are difficult to distinguish, not to mention consumers.
Therefore, they have a good choice of sources of production of LED, or has the consummation LED testing equipment for LED lighting factory is good so bought LED lighting products are more secure.
What are the factors we look at price difference of LED lamps:
1, brightness
Different degrees of brightness of the LED, prices are different.
2, antistatic
Antistatic capability of LED, long life and high prices. Antistatic LED to greater than 700V typically used for LED lighting.
3, wavelength
Wavelength coherent LED,? color, such as a requirement? Color consistent, high prices. There is no LED light manufacturers is difficult to produce color separations instrument pure product.
4, leakage currents
LED is one-way conduction of light-emitting body, if there is a reverse current, is referred to as leakage, leakage current of LED, shorter life expectancy and low price.
5, wide viewing angle
Use different LED beam angle is different. Special angle, higher price. Such as the scattering angle, higher price.
6, long life
Different quality is the key to life, life is determined by lumen. Small lumen maintenance, long life, long life, high prices.
7, LED chips
LED illuminant for chips, different chips, the price varies greatly. Japan and the United States more expensive chip, Taiwan and China's domestic manufacturers of LED chips cost less than Japan and the United States.
Size 8, chip
Chip to edge length, large chip LED's are better quality than the small chip. Price is proportional to the size of the chip.
9, Colloid
Ordinary LED colloid General epoxy resin, plus a UV-resistant and fireproofing agent LED prices more expensive, high quality LED outdoor lighting should be UV-resistant and fire.
LED lighting market is also part of illegal, cheating suppliers, obtaining vendor materials for production of finished products, sale of finished products at abnormally low prices in exchange for cash. There are a few LED lighting manufacturers to unrealistic promises deception dealers and user, and then constantly changes the owner of the firm or ploy to shirk its responsibility and, therefore, where consumers must pay attention to these details.
