Luminaire turning device

Abstract

The invention provides a novel lamp rotation device which comprises a magnetic rotation part and a direction control part, wherein the magnetic rotation part is composed of a driving rotation module, a driven rotation module and an insulation part for insulating and isolating the driving rotation module and the driven rotation module; the driven rotation module is connected with the direction control part; the direction control part is connected with a light source component; the insulation part is composed of a first sealing cylinder structure; and the driven rotation module, the direction control part and the light source component are arranged in the first sealing cylinder structure. According to the technical scheme, the illumination direction of the light source component can be controlled, and the waterproof function of an LED downlight can be realized.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a rotating device for a lamp, especially a rotating device for an LED downlight. Background technique [0002] In the field of lighting, the use of LED downlights is becoming more and more common. Among them, the LED downlight is a lighting fixture embedded in the ceiling and belongs to the directional lighting fixture. [0003] At present, LED downlights usually include: a light source assembly, a cylinder, a rotating chassis and a motor. Among them, the LED downlight connects the cylinder body to the rotating chassis through rivets, and the rotating chassis is connected to the motor through wires. The motor drives the rotating chassis to drive the cylinder body to rotate according to the set direction, so that the lighting direction of the LED downlight can be changed. [0004] However, in some cases, the LED downlight may be immersed in water or other liquids, which may cau...

AI Technical Summary

Problems solved by technology

[0004] However, in some cases, LED downlights may be immersed in water or other liquids, causing malfunctions such as short circuits in LED downlights

For example, when LED downlights are installed in the bathroom, water or water vapor can easily enter the LED downlight. If the insulation layer of the wire connecting the motor and the rotating chassis in the LED downlight is damaged, the water entering the LED downlight will It is easy to cause a short circuit in the circuit, and then cause the failure of the motor and light source components
