LED lighting lighting purchase considerations

How to choose a good LED lighting, there are several places to note:

1, LED brightness is different, the price is different. The LED used for LED lamps should be suitable for laser class I standards.

2. The LED with strong anti-static ability has a long life and therefore a high price. Usually the LED with antistatic capacity greater than 700V can be used for LED lighting.

3, the same wavelength of the LED, the same color, such as the requirements of the same color, the price is high. Manufacturers without LED spectrophotometers have a difficult time producing pure color products.

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

5, the use of different angle LED light emitting angle is not the same. Specific luminescence angles have higher prices.

6, the key to life is different quality of life, life is determined by the light failure. Light decline, long life, high prices.

7. The LEDs of the chip LED are wafers, and the prices of the different wafers vary greatly. Japan and the United States have more expensive wafers. In general, wafer prices in Taiwan are lower than those in Japan and the United States.

8, the size of the wafer size The length of the side of the chip, the quality of large-chip LED is better than the small chip. The price is directly proportional to the size of the wafer.

9, colloidal general LED colloidal epoxy resin is generally, plus anti-ultraviolet and fire retardant LED prices more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire. Each product will have a different design. Different designs are suitable for different purposes. The reliability design aspects of LED lighting include: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, and safety application time. From the perspective of electrical safety, it should be suitable for relevant international and national standards.

As the LED is a new product, China's national standards lag, but the country provides product qualification testing. LED lighting products with international safety certifications (such as GS, CE, UL, etc.) and national product quality certifications are expensive because these products are reliable in terms of safety design. Consumers should pay attention to the authenticity of the authenticity of the certificate. There are not many international safety certifications and national product certifications.

From the health aspect, the use of non-toxic materials to design the product price is high, especially indoor LED lighting, do not be fooled by the use of odor-free LED lighting. Only a few LED manufacturers now use non-toxic materials for production. The method of identification can be used directly with the nose. Odorless products are much cheaper than odors. Similar to lead, mercury, cadmium and other toxins require professional analysis. From the perspective of applicable environmental safety, there is a reliable dust-proof and moisture-proof design, and the price of LED products with data fire protection, UV protection, and low-temperature cracking is high.
