The LED market is booming and mixed, how to choose a good LED product has become a big problem for consumers. In the face of such a market, it is necessary to remain calm and calm, understand the performance characteristics of LED, and make better choices. Everyone introduces the method of selecting an LED light source.
With the rush of the market, as consumers, LEDs still need to be calm, scientific analysis, select the best cost-effective light source and lamps, the following describes the basic performance of several LEDs:
1. The brightness of the brightness LED is different and the price is different. LEDs for LED luminaires shall comply with the laser class I standard.
2, anti-static ability Anti-static ability of the LED, long life, and therefore high price. LEDs with an antistatic greater than 700V can usually be used for LED lighting.
3. LEDs with the same wavelength and wavelength have the same color. If the color is consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure color products.
4. Leakage current LED is a unidirectional conductive illuminator. If there is reverse current, it is called leakage, and LED with large leakage current has short life and low price.
5. LEDs with different illumination angles have different illumination angles. Special lighting angle, the price is higher. Such as the full diffusing angle, the price is higher.
6. The key to different quality of life is life, and life is determined by light decay. Low light decay, long life, long life and high price.
7. The illuminator of the wafer LED is a wafer, and the price of the wafer varies greatly. The chips in Japan and the United States are relatively expensive, and the prices of wafers in Taiwan and China are generally lower than those in Japan and the United States.
8. Wafer Size The size of the wafer is indicated by the side length. The quality of the large wafer LED is better than that of the small wafer. The price is proportional to the size of the wafer.
9, colloidal ordinary LED colloid is generally epoxy resin, LED with anti-ultraviolet and fire retardant is more expensive, high-quality outdoor LED lighting should be resistant to UV and fire. Each product will have a different design and different designs for different uses.
The reliability design of LED lighting includes: electrical safety, fire safety, environmental safety, mechanical safety, health and safety, and safe use time. From the perspective of electrical safety, it should comply with relevant international and national standards.
This article only teaches you how to choose a good LED light source from these nine aspects. I hope readers will help after watching it.
