Characteristics of led spotlights
1, with high purity and rich colors. At present, LED spotlight products cover almost the whole visible spectrum range with high color purity. The traditional way to obtain colored light is to add filters, which greatly reduces the light efficiency.
2, long life, the actual life of led spotlights exceeds 50,000 hours, which is several times or even dozens of times that of general light sources.
3. The light source does not contain mercury, and the light beam does not contain ultraviolet rays. LED spotlight is a solid light source, which is green and environmentally friendly. It is especially suitable for perfume shops, jewelry stores, museums, art galleries and other professional places, and can meet the special requirements of LED spotlights for their display products.
4, can be frequently switched on and off: the life of LED is calculated according to the lighting time, even if it is switched on and off for thousands of times per second, it will not affect the life of LED. In occasions such as decoration that need to be switched on and off frequently, LED lights have absolute advantages.
5. Rich colors: positive white light, warm white light, red, green, blue and other colors. Both small colored lights and neon lights used to decorate the headlights in the living room are very bright.
6, low calorific value: like spotlights, many 220V spotlights will be broken because of fever for a few days. 12V halogen spotlight is lower in calorific value than 220V spotlight, but its brightness can't reach the nominal value due to insufficient transformer power. With LED spotlights, you can work for a long time without a transformer.
7. Energy-saving: The power consumption of LED lamps with the same power is only 65,438+00% of that of incandescent lamps, which is more energy-saving than fluorescent lamps.
Selection skills of led spotlights
Spotlight can be divided into low voltage and high voltage. Consumers had better choose low-voltage spotlights, which have longer life and higher light efficiency. The light efficiency of spotlights is reflected by the power factor. The higher the power factor, the better the light efficiency. The power factor of ordinary spotlights is about 0.5, which is relatively cheap. The power factor of high-quality spotlights can reach 0.99, which is slightly expensive.
Spotlight is generally used to enhance the lighting of decorations, usually embedded in the ceiling or wall. Spotlight generally emits high temperature when working, so you must buy high-quality products, otherwise there will be safety hazards. Transformers should be used for spotlights, and the lamp beads should be of good quality, otherwise the lamp beads of spotlights are easy to break. Think about it, it's quite troublesome to replace the lamp beads on the ceiling.
