Description

Technical Field

[0001] The utility model relates to the technical field of LED downlights, in particular to an LED downlight capable of adjusting color temperature in three stages. Background Art

[0002] LED downlight is a kind of lighting fixture embedded in the ceiling and emitting light downwards. LED downlight is a directional lighting fixture. Only the opposite side can receive light. The beam angle is spotlight, the light is concentrated, and the contrast between light and dark is strong. It highlights the illuminated object more, has a higher lumen, and sets off a quiet environment atmosphere.

[0003] At present, most of the LED downlights with three-stage color temperature adjustment can emit three different color temperatures of light through the white light wick and warm light wick inside. For example, Chinese Patent Publication No. CN221121926U discloses a three-stage adjustable color temperature LED downlight. However, after the LED downlight is fixed to the ceiling by spring clips, maintenance personnel need to remove the LED downlight from the ceiling by hand, and the contact between the LED downlight and the ceiling is relatively close, which makes it more troublesome to remove the LED downlight. At the same time, when the soft light plate on the LED downlight is hit, the impact force directly acts on the soft light plate, which makes the soft light plate easily damaged. Utility Model Content

At the same time, when the soft light plate on the LED downlight is hit, the impact force directly acts on the soft light plate, which makes the soft light plate easy to be damaged. Therefore, a LED downlight with three-stage switching and color temperature adjustment is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
