As a consumer, the choice LED Street Light is still to be calm, scientific analysis, the choice of the best cost-effective light sources and lamps, LED Here are a few basic properties:
A brightness 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. Usually static than 700V the LED can be used for LED Lighting.
3, the wavelength consistent wavelength of the LED, the same color, the same color as the requirements, the price is high. No LED spectral separation device manufacturers is difficult to produce pure colors.
4, the leakage current is led street light is one-way conductive light, if there is reverse current is called leakage, leakage current is large LED, life is short, low prices.
5, different emission angles uses LED luminous angle is not the same. Special light angle, the higher the price. If all diffusion angle, higher prices.
6, the key is the quality of life of different life, life is determined by the light fades. Light decay, long life, long life, high price.
7, chip LED chip emitting body is different chips, prices vary widely. Japan, the United States more expensive chips, generally made ??in Taiwan and chip prices lower than Japan, the United States.
8, the size of the chip size of the chip to the side length of said quality big chip led street light is better than a small chip. The price of the same chip size is proportional.
9, colloidal ordinary LED colloidal generally epoxy resin, plus a UV resistant and fire retardant of LED expensive, high-quality outdoor LED lighting should be UV and fire.
Each product will have a different design, different designs for different purposes, the reliability of the design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use of time and other factors. From electrical safety point of view, should be consistent with relevant international and national standards. Since LED is a new product, the Chinese national standard lag, but the state provides product qualification testing. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification of LED lighting prices to be higher, because these products are designed to be safe and reliable. Consumer attention is to carefully identify the authenticity of the certificate, there are now international and national product safety certification certificates are not many manufacturers.
From a health aspect, the use of non-toxic materials designed product prices to be high, especially indoor LED lighting, do not choose the smell of cheap LED lighting, LED manufacturers currently only a handful of non-toxic material is produced, to identify ways directly with the nose respectively, the smell of the product much lower price than those without odor. Professionals need a similar analysis of lead, mercury, cadmium and other toxins. From the applicable environmental safety perspective, there is a reliable dust-proof design, material fire, anti-UV, anti-low temperature cracking price LED products is high.
