LED as a light source began to be applied to lighting fixtures, but only a few decades, but it has achieved great development. At present, there are many kinds of LED lighting fixtures, including LED downlights, LED spotlights, LED downlights. LED bulbs, LED downlights, etc., but the most promising development is LED downlights. The main advantages and features of LED downlights are as follows: First, the LED downlight has good starting performance, fast and reliable, and only has a millisecond response time, which can achieve full light output. Second, the LED downlight is resistant to vibration, weather resistance and long life. Third, the LED downlight can be highly maintainable, and the LED light source can be composed of multiple sets of LED modules. The LED downlight can also be composed of multiple sets of LED cavity modules, which do not interfere with each other and are convenient to maintain. The power supply and the light source are designed independently. When the damage occurs, only the problematic part needs to be replaced. The individual damage does not have an excessive influence on the normal illumination, and the whole lamp is not required to be replaced. Fourth, LED downlights are highly adaptable. The LED downlight does not have a startup time problem, and the power can be immediately operated normally without waiting for a long time. The light source has good color rendering, close to natural light, quick and flexible installation, adjustable angle at any angle, strong versatility and wide application range. Fifth, LED downlights have a higher color rendering index. The color rendering index of the national standard for this interval is Ra=60, and the color rendering index of the LED light source is generally higher than that of the conventional light source. At the current level, the color rendering index of LED downlights can reach 70 to 85. The advantages of LED downlights are obvious, and they are more favored by consumers. Currently, they are mainly used in office lighting, home lighting, large shopping malls, supermarket lighting and factory lighting.
