Abstract

The invention discloses an annular LED illumination device capable of adjusting the light-emitting direction. The annular LED illumination device capable of adjusting the light-emitting direction is characterized in that the illumination device comprises an annular lamp structure body and an annular lamp housing; LED light sources are installed on the outer side of the annular lamp structure body and arranged at equal intervals in the circumferential direction; the illumination device further comprises a fixing assembly; the illumination device is fixed to a ceiling through the fixing assembly; the annular lamp housing is a transparent or semi-transparent lamp housing which is made of acrylic materials or polycarbonate materials; controllable and adjustable fan blades which can be adjusted up and down in the axial direction are fixedly installed on the upper surface and the lower surface, in the axial direction, of the illumination device, so that the light-emitting direction of the LED light sources is adjusted. According to the annular LED illumination device capable of adjusting the light-emitting direction, the illumination brightness and the illumination direction can be adjusted in a user-friendly mode.

Description

technical field [0001] The invention belongs to the field of lighting, and more particularly relates to a ring-shaped LED lighting device capable of adjusting the direction of light emission. Background technique [0002] In the field of indoor lighting technology, it has always been the direction for engineers to improve and develop to achieve effective control of lamps and meet the needs of the human eye for light in various situations. [0003] In the traditional lighting scheme, it is affected by factors such as the shape of the light source, the installation size, and the power level. Generally, the adjustment of LED light emission in the prior art generally uses the control method of the driving current to adjust the light emission brightness. The adjustment method often has high requirements on the driving components, and the LED lamp may be damaged when the brightness is adjusted many times. Contents of the invention [0004] In view of the above defects or improv...
