With the development of modern society, people's living standards improve, lighting has also undergone great changes, and now a new form of light source LED, because of its high brightness, low heat, long life, non-toxic, recyclable And other advantages, as people's daily life, the most common lighting source, and LED lamps and the quality of which LED lamp beads which has a great relationship, a good LED lamp beads made of LED lighting products in the effect of more it is good.
The company professionals to teach you: how to determine the LED light source is good or bad?
1, brightness LED brightness is different, the price is different. LED for LED lamps should meet the laser class Ⅰ standard.
2, anti-static ability Antistatic ability LED, long life, and thus high prices. Usually anti-static greater than 700V LED can be used for LED lighting.
3, the wavelength of the same wavelength of the LED, the same color, such as the required color, the price is high. Producers who do not have LED spectrophotograms are hard to produce purely color products.
4, leakage current LED is a one-way conductive light, if there is reverse current, known as leakage, leakage current LED, short life, low prices.
5, the use of different angles LED light angle is not the same. Special light angle, the price is higher. Such as full diffuse angle, the price is higher.
6, the quality of life is the key to the quality of life, life by the decay of light. Light fades small, long life, long life, high prices.
7, wafer LED luminous body for the wafer, different chips, the price difference is very large. Japan, the United States of the chip more expensive, generally Taiwan and domestic chip prices lower than Japan, the United States.
8, the size of the chip chip size to the side length, large chip LED quality is better than the small chip. The price is proportional to the size of the chip.
9, colloidal colloidal LED colloid is generally an epoxy resin, plus anti-ultraviolet and fire retardant LED more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire. Each product will have a different design, different designs for different purposes, LED lighting reliability design includes: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, safe use of time and other factors. From the electrical safety point of view, should be consistent with the relevant international and national standards.
Has been widely used in many occasions, such as traffic lights, display, car brake lights, decoration, computers, electronic toys gifts, telephones, advertising, etc., when we choose LED products, in order to choose good quality LED products , It is necessary to LED products inside the LED lamp beads package brand to understand, try to choose those big word of mouth is your favorite to buy low-quality LED products, a very good choice. LED lamp beads manufacturers of different production standards, manufacturing processes, staff operations are different, to produce the LED lamp beads is even a significant level of the points.
As the LED is a new product, China's national standards lag, but the state to provide product testing. The price of LED lighting with international safety certification (such as GS, CE, UL, etc.) and national product quality certification is high because these products are reliable in safety design. Consumers pay attention to is to seriously identify the authenticity of the certificate, there are international safety certification and national product certification manufacturers are not many.http://www.gentwin.com/
