How to choose healthy and environmentally LED lighting

Regarding LED lighting, there are several places to pay attention to:

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

2. LEDs with strong anti-static ability have long life and high prices. Usually LEDs with anti-static greater than 700V can be used for LED lighting.

3. LEDs with the same wavelength have the same color. If the same color is required, the price will be high. It is difficult for a manufacturer without an LED spectrophotometer to produce a product with pure color.

4. Leakage current LED is a one-way conductive luminous body. If there is a reverse current, it is called leakage current. LEDs with large leakage current have short life and low price.

5. LEDs with different lighting angles have different lighting angles. The special light angle is more expensive.

6. The key to different quality of lifespan is lifespan, which is determined by light decay. Low light decay, long life and high price.

7. The light-emitting body of chip LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive. Generally, the prices of chips in Taiwan and China are lower than those in Japan and the United States.

8. The size of the chip is represented by the length of the side. The quality of the large chip LED is better than that of the small chip. The price is proportional to the wafer size.

9. The colloid of ordinary LED is generally epoxy resin. The price of LED with anti-ultraviolet and fire-proof agent is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fire-proof. Each product will have a different design, and different designs are suitable for different purposes. The reliability design of LED lighting contains factors such as electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, and safe application time. From the point of view of electrical safety, it should conform to relevant international and national standards.

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

In terms of health, the price of products designed with non-toxic materials is higher, especially indoor LED lighting. Don’t be cheap and choose LED lighting with peculiar smell. At present, only a few LED manufacturers use non-toxic materials for production. The method of identification can be directly distinguished by nose. The price of odorless products is much lower than that of odorless products. Toxins such as lead, mercury, and cadmium require professional analysis. From the perspective of applicable environmental safety, LED products with reliable dust-proof and moisture-proof design, material fire-proof, UV-proof, and low-temperature cracking resistance are expensive.
