How to choose a good LED lamp?

About LED lighting, there are several places need to pay attention to:

1, LED brightness is different, the price is different. LED for LED lamps shall be suitable for laser class.

2, antistatic ability of LED, long life, and high price. Usually anti-static 700V greater than LED can be used for LED lighting.

3, the wavelength of the same LED, the same color, such as the requirements of the same color, the price is high. It is very difficult to produce pure color products without the manufacturers of LED spectrophotometer.

4, leakage current LED is a one-way conductive body, if there is a reverse current, it is called leakage, leakage current LED, short life, low price.

5, the use of different luminous angle of LED its luminous angle is not the same. Specific light-emitting angle higher prices.

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

7, the wafer LED light-emitting chip, different chips, the price difference is very large. Japan, the United States more expensive chips, the average price is lower than in Taiwan, Japan, the United States, the lowest domestic.

8, the size of the chip size to the side of the chip, the quality of the large chip LED is better than small chips. The price is proportional to the size of isomorphous.

9, the gel of the general LED colloid is generally epoxy resin, plus UV and fire retardant LED price is more expensive, high quality outdoor LED lighting should be resistant to ultraviolet light and fire.

How to choose a good home LED lights?

Each product has a different design, different designs for different purposes, the reliability design of LED lighting style: electrical safety, fire safety, environmental safety, suitable for mechanical safety, health and safety, security application time etc.. From the electrical safety point of view, should be suitable for the relevant international and national standards. Since LED is a new product, China's national standards lag, but the state provides product qualification test. With international safety certification (such as GS, CE, UL, etc.) and the national product quality certification of LED lighting price is high, because these products are reliable in safety design. Consumers are paying attention to the authenticity of the authenticity of the certificate, there are international security certification and national product certification is not much.

From the health, the use of non-toxic materials designed to high prices, especially indoor LED lighting, do not be cheap to choose the smell of LED lighting. Now only a few LED manufacturers are non-toxic material production, the method can be used directly to identify the nose, the smell of the product is much lower than the price of no smell. 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, data fire, anti UV, anti cracking of low temperature LED product prices.
