Nine basic properties to pay attention to when choosing LED light sources

As the market is rushing to buy, as a consumer, you still need to be calm and make scientific analysis when choosing LEDs , and choose the light sources and lamps with the best cost performance. The following introduces the basic performance of several LEDs:

1. Brightness The brightness of LED is different, and the price is different. The LED used in LED lamps should meet the laser grade I standard.

2. Antistatic Electricity LEDs with strong antistatic ability have long life and are therefore expensive. Usually, LEDs with antistatic greater than 700V can be used in LED lighting .

3. LEDs with consistent wavelengths have consistent colors. If the color is required to be consistent, the price will be high. It is difficult for manufacturers without LED spectrometers to produce products with pure colors.

4. Leakage Current LED is a unidirectional conductive light source. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.

5. Lighting Angle LEDs with different uses have different lighting angles. Special lighting angles have higher prices. For example, full diffuse angles have higher prices.

6. Lifespan The key to different quality is lifespan, which is determined by light decay. Small light decay means long lifespan, while long lifespan means high price.

7. The light source of chip LED is chip. Different chips have different prices. Japanese and American chips are more expensive. Generally, the price of Taiwanese and domestic chips is lower than that of Japanese and American chips.

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

9. Colloid The colloid of ordinary LED is generally epoxy resin. LED with anti-ultraviolet and fire retardant is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. Each product will have different designs, and different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.

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

From the health aspect, products designed with non-toxic materials are more expensive, especially indoor LED lighting. Don't be greedy and choose LED lighting with odor. Currently, only a few LED manufacturers use non-toxic materials. You can distinguish them directly with your nose. Products with odor are much cheaper than those without odor. Toxins such as lead, mercury, and cadmium need to be analyzed by professionals. From the perspective of environmental safety, LED products with reliable dust and moisture-proof design, fireproof, UV-proof, and low-temperature cracking-proof materials are more expensive.
