Description

Improved structure ceiling fan light

Technical field

The invention relates to the technical field of ceiling fan lamps, in particular to a ceiling fan lamp with improved structure.

Background technique

Decorative ceiling fans, commonly known as ceiling fan lights, are a combination of lights and ceiling fans that have both lighting and decorative effects as well as fan blowers. At present, the better sales on the market is an invisible ceiling fan light that can hide the blade. The advantage of the invisible ceiling fan light is that when the user does not use the fan function, the blade will automatically close and hide (storage) without affecting the appearance. When the user uses the fan function, the blade rotates with the turntable, and the blade is pulled out under the centrifugal force, that is, the blade is unfolded.

See Chinese Invention Patent No.: 200680032396.1, entitled: Combined luminaire and ceiling fan, which uses a sun gear that is mounted to the blade support and that is configured to mesh with a planet gear that pivots about the blade. However, the ceiling fan lamp of the above structure has the following disadvantages: (1) the blade is mounted on the blade support member through the pivot shaft, the planetary gear and the sun gear, and the structure is complicated and the installation is cumbersome; (2) the blade needs to be deployed due to the deployment. The planetary gear and the sun gear mesh with the rotary drive, which generates a large noise during operation, and the tooth resistance is large, the smoothness of the blade unfolding and storing is insufficient, and the wear is easy, and the service life is short.

Summary of the invention
