Abstract

The invention discloses a fireproof down lamp. An LED pressing plate is arranged in a cylinder body, an LED light source plate is arranged on the LED pressing plate, the lower end of the cylinder is connected to a surface ring assembly, the surface ring assembly comprises a surface ring bracket and a rotary surface ring; a lens is movably arranged in the surface ring bracket; a sealing piece is arranged on the lens; the upper connecting end of the sealing piece is connected to the surface ring bracket; the lower connecting end is connected to the lens lower end; the lens is provided with a limiting buckle, a pressing self-locking structure capable of being matched with the limiting buckle to limit vertical movement of the lens is arranged in the cylinder body, a stirring handle is arrangedon the rotating surface ring, and the upper end of the stirring handle penetrates out of the sealing piece in a sealed mode and is connected with a switch handle of a color temperature adjusting switch fixedly arranged in the cylinder body. According to the invention, the focal length can be changed by pressing the lens, the color temperature adjustment can be realized by rotating the rotary surface ring, and the rotation of the rotating surface ring and the up-and-down movement of the lens can be sealed at the same time by using only one sealing piece, so that the IP65 protection grade requirement can be met.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to a fireproof downlight. Background technique [0002] Chinese document CN209801299U (application date: May 24, 2019) discloses a fireproof downlight, including a fireproof cylinder body, a light source device, a toggle switch and an adjustment ring, and the light source device and the toggle switch are installed separately. In the interior of the fireproof cylinder body, and the toggle switch is electrically connected to the light source device, the adjustment ring is rotatably clamped on the opening end of the fireproof cylinder body, the adjustment ring and the The toggle end of the toggle switch is fixedly connected. This technical solution can touch the toggle switch by turning the adjusting ring to achieve the purpose of adjusting the color temperature, but the technical solution has a single function, which can only adjust the color temperature, and lacks diversity...
