1. Field of the Invention
The present invention relates to a light unit and, in particular, to an assembly structure of a light unit.
2. Description of Related Art
The illumination angle and range of a traditional light unit are mostly fixed and cannot be adjusted according to the requirement of the installation place. Also, few light units which can adjust the illumination angle and range have the disadvantages of the complex adjustment structure and high manufacturing cost. Besides, even if the existing light unit can adjust the illumination angle, the illumination angle can only be adjusted in one direction; thus, a complete and full adjustment for illumination area is not available and the improvement thereof is required.
In view of foregoing, the inventor pays special attention to the above existing technology and researches with the application of related theory to overcome the above disadvantages regarding the above related art, which becomes the goal of the inventor's improvement.
One objective of the present invention is to provide an assembly structure of a light unit, which can make a multi-direction adjustment in angle.
To achieve the above objective, the present invention provides an assembly structure of a light unit, which comprises a lighting device, a pair of supporting bases, an adjustment frame, a first fastener, an adjustment plate, and a second fastener. The lighting device comprises a light source and a heat-dissipation module thermally connecting to the light source. The pair of supporting bases individually support two opposite sides of the heat-dissipation module. The adjustment frame spans the pair of supporting bases and covers the lighting device. The adjustment frame comprises two supporting arms and a supporting plate connecting the two supporting arms. Each of the two supporting arms is provided with a first axial hole and a plurality of first adjustment holes circularly surrounding the first axial hole. Each of the pair of supporting bases is provided with a first throughhole corresponding to the first axial hole of the supporting arm and at least one first lockhole. The first lockhole can be selectively aligned with one of the first adjustment holes. The first fastener passes through the first throughhole and is fastened to the first axial hole. The adjustment plate is disposed on a side of the supporting plate away from the lighting device. The adjustment plate is provided with a second axial hole and a plurality of second adjustment holes circularly surrounding the second axial hole. The supporting plate is provided with a second throughhole corresponding to the second axial hole and at least one second lockhole. The second lockhole can be selectively aligned with one of the second adjustment holes. The second fastener passes through the second throughhole and is fastened to the second axial hole.
Another objective of the present invention is to provide an assembly structure of a light unit, which is provided with power racks disposed outside of the supporting bases. In this way, the power supplies can be directly placed in the power racks without finding other space to be placed, which improves convenience of assembly.
Compared with the prior art, the lighting device of the light unit of the present invention is fixed to the supporting bases. When the angles of the supporting bases change with respect to the adjustment frame, the lighting device will change the illumination angle following the movements of the supporting bases. Thus, the light unit performs the adjustment of the first direction by means of the adjustment frame and the supporting bases; also, when the angle of the adjustment frame changes with respect to the adjustment plate, the lighting device will also change the illumination angle at the same time following the movement of the adjustment frame. Thus, the light unit performs the adjustment of the second direction by means of the adjustment frame and the adjustment plate. Therefore, the light unit can perform the angle adjustment in two directions based on the practical demand to meet the requirements of the illumination angle and range and improve the practicability of the present invention.
The detailed description and technical details of the present invention will be explained below with reference to accompanying figures. However, the accompanying figures are only for reference and explanation, but not to limit the scope of the present invention.

The adjustment frame 30 comprises two supporting arms 31 and a supporting plate 32 connecting the two supporting arms 31. Each of the two supporting arms 31 is provided with a first axial hole 310 and a plurality of first adjustment holes 311 circularly surrounding the first axial hole 310. Preferably, the first adjustment holes 311 are disposed surrounding the first axial hole 310 in a 360-degree arrangement.
Moreover, each of the pair of supporting bases 20 is provided with a first throughhole 200 corresponding to the first axial hole 310 of the supporting arm 31 and at least one first lockhole 201. The first lockhole 201 can be selectively aligned with one of the first adjustment holes 311. That is, the angle of the adjustment frame 30 with respect to the first direction 100 can be fixed by means of the alignment between the first adjustment hole 311 and the first lockhole 201. The first adjustment holes 311 of the left and right supporting arms 31 of the adjustment frame 30 will be individually aligned with the first lockholes 201 of the left and right supporting bases 20. At such an angle, the first fastener 40 is passed through the first throughhole 200 and is fastened to the first axial hole 310 such that the angle of the adjustment frame 30 with respect to the first direction 100 is fixed.
Preferably, the light unit 1 further comprises a plurality of first adjustment fasteners 70 and there are plural first lockholes 201. When the angle of the adjustment frame 30 with respect to the first direction 100 is fixed, the first lockholes 201 will be simultaneously aligned with the first adjustment holes 311 at different positions such that first adjustment fasteners 70 are individually fastened to the corresponding first lockhole 201 and the first adjustment hole 311 which are aligned to each other. In this way, a more stable combination between the adjustment frame 30 and the pair of the supporting bases 20 in the first direction 100 can be achieved.
Further, the adjustment plate 50 is disposed on a side of the supporting plate 32 away from the lighting device 10. The adjustment plate 50 is provided with a second axial hole 500 and a plurality of second adjustment holes 501 circularly surrounding the second axial hole 500.
