LED lighting has received widespread attention as a new generation of lighting. Relying on LED packaging alone cannot make good lighting fixtures. This article mainly introduces LED lighting from the aspects of electronic circuits, thermal analysis, and optics. First, LED lighting design is introduced.
As people’s attention to the environment has increased in recent years, LED lighting has received widespread attention as a new generation of lighting. At the exhibition, as long as the booths related to LED lighting are crowded with people, at the same time, LED lighting also appears more in our daily lives. The LED lights that can be consumed by general households are bulb-type LED lights sold by major lighting manufacturers. In addition, many companies have successively developed fluorescent-type LED lights. In this case, more companies are bound to participate in the LED lighting industry.
LED lamps have different characteristics from traditional light sources such as incandescent lamps and fluorescent lamps. Relying on LED packaging alone cannot produce good lighting fixtures. In order to design a better LED lighting fixture, the correct optical design of the LED must be different from the traditional light source.
The reason why LED lighting is highly anticipated is energy saving and long service life. Indeed, compared with incandescent lamps, current bulb-type LED lamps are more efficient. However, compared with LED lighting fixtures, fluorescent lamps are still higher. This is because although a single LED chip is more efficient than a fluorescent lamp, it reduces the luminous efficiency due to heat generation. When AC power is converted to DC power, the power efficiency becomes low, and the light efficiency is reduced due to the conversion of light distribution and the use of diffusers. The efficiency of LED lighting fixtures drops.
