Select nine basic properties of the LED light source

With the rushing headlong into the market, as consumers, still choose to be calm, scientific analysis, selection of the best cost-effective light source and lamp, introduces the basic properties of several of the following:

1, brightness brightness is different, different prices. Standard for laser grade I.

2, antistatic ability of antistatic ability, long service life, so the price is high. Usually antistatic than 700V can be used for lighting.

3, wavelength consistent, uniform color, such as color, the price is high. It is very difficult for a manufacturer to produce pure color products without a spectrophotometer.

4, the leakage current is a one-way conductive luminous body, if the reverse current is called leakage current leakage, short life, low price.

5, uses different light emitting angle the angle is not the same. Special lighting angle, high price. Such as full diffusion angle, higher prices.

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

The luminous body 7, chip chip, different chips, the price difference is very great. Japan, the United States more expensive chips, the average price of Taiwan and domestic chips lower than Japan, the United states.

8, wafer size chip size to side said that the wafer quality is better than small chip. The price is proportional to the size of isomorphous.

9, ordinary colloid colloid general epoxy resin, with UV resistant and fire retardant price is more expensive, high-quality outdoor lighting should be UV and fire. Each product has a different design, different designs for different purposes, lighting the reliability design include: electrical safety, fire safety, environmental safety, suitable for mechanical safety, health and safety, safe use time etc.. From the electrical safety point of view, should comply with the relevant international and national standards.

Is due to new products, Chinese lag the national standard, but the national product qualification testing. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification of lighting price is high, because these products are reliable in safety design. Consumers are paying attention to identify the authenticity of the certificate, there are now international safety certification and national product certification is not much.

From healthy, nontoxic materials design products to the high price, especially for indoor lighting, do not use cheap odor lighting, currently only a few manufacturers are manufactured using non-toxic materials, identify the method can be directly used nose respectively, smell a lot of products at lower prices than no odor. Similar to lead, mercury, cadmium and other toxins need professional analysis. From the point of view of the application of environmental safety, there is a reliable dustproof design, material fire, anti UV, anti low temperature cracking of the high price of the product.
