Relevant parameters commonly used in purchasing LED energy-saving lamps
At present, with the support of national policies for LED lamps and the energy-saving effect of LED lamps, the application of LED lamps is gradually popularized. Basically, jewelry stores and hotels can see traces of LED lighting products, and home decoration is gradually used more and more. The spotlights used for family background walls have basically started to choose LED spotlights.
Looking at the market, it can be said that every lighting store now has LED products on sale, with many brands and chaotic prices ranging from ten yuan to several hundred yuan, and consumers are not sure. On the other hand. Enterprises that produce LED lamps also rush headlong into the ranks of LEDs, resulting in uneven quality of LED lamps and great price difference. Faced with such a market, many consumers often don't know how to choose, so. Knowing some parameters and basic performance of LED energy-saving lamps is a great skill for consumers to choose high cost-effective LED lamps. Below, I will introduce some basic properties of LED to help you choose LED lamps.
1, brightness. The brightness of LED is different, and the price is different. The LEDs used for LED lamps shall meet the laser class I standard.
2. Anti-static ability. The LED with strong antistatic ability has a long service life, so the price is high. Generally, LEDs with antistatic performance greater than 700V can be used for LED lighting.
3. Wavelength. The LED with the same wavelength has the same color. If consistent colors are required, the price is high. It is difficult for manufacturers without LED spectrometers to produce products with pure colors.
4. Leak. At present, LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LED with large leakage current has short life and low price.
5. glow. LEDs with different angles have different light emitting angles. Special luminous angle, high price. Such as the total diffusion angle, the price is higher.
6. Life span. The key to different quality is life span, which is determined by light decay. Small light attenuation, long service life, long service life and high price.
7. wafer. The luminous body of LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive, while the prices of chips in Taiwan Province Province and Chinese mainland in China are generally lower than those in Japan and the United States.
8. Wafer size. The size of the chip is expressed by the side length, and the quality of LED with large chip is better than that with small chip. The price is proportional to the chip size.
9, colloid. The colloid of ordinary LED is generally epoxy resin, and the LED with ultraviolet protection and fire retardant is more expensive. High-quality outdoor LED lighting should prevent ultraviolet rays and fire.
The above is the analysis of some common parameters when purchasing LED energy-saving lamps. I believe that everyone can make a suitable choice when purchasing LED lights. As the saying goes, you can't choose poor quality LED lights for the sake of cheapness, which will not pay off. You can't blindly seek the so-called brand, only the one with high cost performance is the best.
