Weak current College】 【from nine area select LED light source】.

<br> <br> With yihongershang market, as consumers, selection of LED remains calm, scientific analysis, selection of the best price / performance ratio of the light source and lamps, here are some basic properties: LED <br> 1, a .brightness LED brightness, the prices are different. For LED lighting of the LED should be consistent with the laser class Ⅰ class standards. <br> 2, antistatic antistatic ability strong LED, long life and high prices. Usually the antistatic LED to greater 700V .to LED lighting. <br> 3, wavelength LED wavelength consistent, color match, if the color consistent price high. No LED beam separations instrument manufacturers difficult production color pure product. <br> 4, leakage current LED lighting is a one-way .conductive, if there is a reverse current, it is called leakage, leakage current large LED, short service life, low prices. <br> 5, wide viewing angle, uses different LED to their wide viewing angle. Special luminous point, higher prices .. If the total diffuse point, higher prices. <br> 6, the key to life with different quality is life, life decisions by optical attenuation. Light attenuation is small, long life, long life, high prices. <br> 7, .chip LED the luminous body for chip, different chip, the price difference is very big. Japan, United States of chip more expensive, Taiwan and domestic chip prices lower than November, the United States. <br> 8, wafer size chip size to .side indicated that large chip LED's quality is better than small chips. The price is proportional with the chip size. <br> 9, colloidal ordinary LED colloidal General epoxy resin, with anti-UV and fire protection agents LED expensive, high-quality outdoor .LED lighting should be UV resistance and fire safety. Each product has a different design, different designs for different purposes, LED lighting for reliability design include: electrical safety, fire safety, the application of environmental security, safety, health and safety, security, .use the time and other factors. From the perspective of electrical safety shall be consistent with relevant international and national standards. <br> Because of the LED is the new product, the Chinese national standard lag, but countries provide product qualification testing. With international .security certification (such as GS, CE, UL, etc.) and the national product quality certificate of led lighting to high prices, because these products at security design is reliable. Consumers pay attention to careful identification of the certificate of authenticity, now have .international safety certification and national product certificate of quality manufacturers. <br> From health aspects, using non-toxic materials and design of the product price, especially the indoor LED lighting, please don't be cheap choice smell of LED lighting, currently only .a handful of House LED manufacturers is non-toxic materials production, identification of ways you can directly use nose respectively, smelly products than no smell of lower prices. Like lead, mercury, cadmium, and other toxins need professional analysis. From the applicable environment .safe, reliable dust-proof design, materials, fire protection, anti-UV, anti cracking of LED products. <br> <br> <br>.
