Compared with traditional downlights, they have the following advantages: energy saving, low carbon, long life, good color rendering, and fast response.

The light source is hidden inside the architectural decoration, the light source is not exposed, there is no glare, and the visual effect is soft and uniform.

[0003] Among them, the current technology authorization announcement number CN213872448U proposes a portable rotating heat dissipation LED downlight including an LED downlight body and a mounting box, the top surface of the LED downlight body is provided with a heat sink, and the mounting box is provided above the heat sink, and a reduction motor is installed on the bottom upper surface of the mounting box, and the output end of the reduction motor is fixedly connected to a turntable.
