How to buy LED lighting

Xiao Bian, according to my understanding of LED lighting, to share my experience and share!

LED brightness (MCD) is different and the price is different. In the purchase of LED lamps should be selected laser grade I standard lighting products.

Anti-static ability The LED with strong anti-static ability has a long life and therefore a high price. Therefore, when you purchase, look for anti-static electricity that is greater than 700V before you purchase it.

Wavelength-consistent LEDs have the same color, and if the requested color is the same, the price is high. Manufacturers without LED spectrophotometers have difficulty producing pure-color products, so they should carefully observe the purity of the product's color.

Leakage current LED is a one-way conductive light, if there is reverse current, it is called leakage, leakage current LED, short life, low price, this should be measured by the corresponding equipment, generally ignored, be a Kind of understanding it.

The different angles of light used for different light emitting angles are different. Specific light angle, higher prices. Such as the full diffuse angle, so you can not ignore the light angle of your purchase of LED lamps.

The key to different quality of life is life, which is determined by light decay. The light decay is small, the service life is long, and the price is high. This is usually a comparison between the three companies, and the same kind of product is selected to be expensive to buy.

The emitter of the chip LED is a wafer, and the price of the different wafers varies greatly. Japan and the United States have more expensive chips. In general, Taiwan and domestic wafer prices are lower than Japan and the United States (CREE). This is also the only difference between the experts. The general consumption is really more to be compared. This can be judged from the price level. The only more expensive the better.

Wafer size The size of the wafer is expressed in terms of side length, and the quality of the large-chip LED is better than that of the small wafer. The price is proportional to the size of the chip, and you should be cautious about seeing that you don't meet this principle.

Colloidal General LED colloid is generally epoxy resin, plus anti-ultraviolet radiation and fire retardant LED prices are more expensive, high-quality Outdoor Led Lighting should be anti-ultraviolet and fire. Therefore, as a consumer must pay attention to the authenticity of the authenticity of the certificate, there are not many international safety certification and national product certification manufacturers, make sure to check the Internet before buying, and don’t worry when buying. know.
