no. 1 approach

[0036] figure 1 A front view of the first embodiment of the lighting device of the present invention is shown. Such as figure 1 As shown, a rotating assembly 1 is rotationally connected with a fixed assembly 2 through a rotating shaft assembly 4, and a motor drive mechanism (not shown) can drive the rotating shaft assembly 4 (in this embodiment, the rotating shaft assembly 4 only includes one rotating shaft) The rotation further brings the rotating assembly 1 to rotate relative to the fixed assembly 2 . Wherein, the rotating assembly 1 is provided with a light guide plate.

[0037] figure 2 show figure 1 top view. Such as figure 2 As shown, the rotating assembly 1 has a rectangular shape as a whole and the rotating assembly 1 is provided with two first installation parts 11 fixed to the light guide plate, the fixed assembly 2 has a rectangular shape as a whole and the fixed assembly 2 is provided with a mounting part 11 that cooperates with the first installation part ...

[0046] Figure 6 A top view of a third embodiment of the lighting device of the present invention is shown. Such as Figure 6 As shown, the rotating assembly 1 is trapezoidal in shape and there are four in number, and the four rotating assemblies 1 are respectively rotatably connected to the fixed assembly 2 through the rotating shaft assembly 4 (including one rotating shaft in this embodiment). The fixed assembly 2 is circular, and four rotating assemblies 1 are evenly arranged along the circumference of the fixed assembly 2 . A motor driving mechanism (not shown) can drive the rotating shaft assembly 4 and then bring the rotating assembly 1 to rotate relative to the fixed assembly 2 . Wherein, the rotating assembly 1 is provided with a light guide plate.

[0047] Figure 7 show Figure 6 The structural diagram of the motor drive mechanism of the lighting device in . Such as Figure 7 As shown, the motor drive mechanism 3 includes a motor 31 and a first transmission ge...

Abstract

The invention relates to an illumination device which comprises a rotating assembly, a fixing assembly, a motor driving mechanism and a rotating shaft assembly, wherein the rotating assembly is provided with a light guide plate; the rotating assembly is connected with the fixing assembly through the rotating shaft assembly, so that the rotating assembly can rotate in a preset range around the rotating shaft assembly relative to the fixing assembly; and in addition, the motor driving mechanism is in transmission connection with the rotating shaft assembly, so that the motor driving mechanism can drive the rotating assembly to rotate relative to the fixing assembly by driving the rotating shaft assembly. The posture of the rotating assembly provided with the light guide plate is adjustable,so that light distribution of the illumination device is variable; and different light distribution requirements can be met.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an illuminating device with a rotatable light guide plate. Background technique [0002] In an existing lighting device, a light guide plate is usually provided to make the luminescence uniform. However, in the prior art, the light guide plate in the lighting device is often fixed, and the posture of the light guide plate cannot be adjusted, which leads to the invariable light distribution of the lighting device and cannot adapt to different light distribution requirements. Contents of the invention [0003] Based on the above-mentioned defects in the prior art, the object of the present invention is to provide a lighting device with adjustable posture of the light guide plate. [0004] For this reason, the present invention provides the following technical solutions. [0005] The present invention provides a lighting device, the lighting device includes a rotating assembly, a fixed ...
