Detailed Description
Specific embodiments of the present invention will be described in further detail below based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to 4, the spot lamp of the present embodiment includes a lamp housing 100, a light source assembly 200 disposed in the lamp housing 100, a rotating arm 300 connected to the lamp housing 100, and a tensioning and mounting portion 400 connected to an inner wall of the lamp housing 100 in an interference fit manner and capable of being tightened or loosened.
The rotating arm 300 of the embodiment is connected to the lamp housing 100 through the tension mounting part 400 capable of adjusting tightness, so that when the length of the housing 100 is adjusted due to power change of the spot lamp, the mounting manner of the rotating arm 300 is kept unchanged, thereby improving the universality of parts, reducing the manufacturing cost, simplifying the structure of the lamp housing 100, adopting tube manufacturing, having lower cost and better heat dissipation compared with cast molding.
The light source assembly 200 may adopt the prior art, which is not the focus of the present application, and is not described again.
The tight and tight installation part 400 is tightly fitted to the inner wall of the lamp housing 100 in an interference manner, and is separated from the inner wall of the lamp housing 100 when being loosened.
In a specific implementation manner, a mounting plate capable of abutting against at least a part of the inner wall of the lamp housing 100 may be provided, and then a pressing force is provided to deform the mounting plate to press against the inner wall of the lamp housing 100, so as to implement an interference fit connection, where the pressing position may be an edge, but it is easy to deform the lamp housing 100, therefore, in this embodiment, the tensioning mounting portion 400 includes the mounting plate 401, the through groove 402 and the adjusting screw 403. A through slot 402 is opened on the mounting plate 401 and has one end extending to the edge; one end of the adjusting screw 403 is inserted into the through groove 402, the other end of the adjusting screw is connected with the adjusting nut 404, and the through groove 402 is expanded in the process of locking the adjusting screw 403 and the adjusting nut 404, so that the outer diameter of the mounting disc 401 is increased to be connected with the lamp housing 100 in an interference fit manner. The through groove 402 is matched with the adjusting screw 403, so that the width of the through groove 402 can be changed conveniently, and the outer diameter of the mounting disc 401 is changed to enable the lamp housing 100 to be connected in an interference fit manner.
In this embodiment, for reliable and convenient assembly, the adjusting nut 404 is provided with a upwardly protruding latch 4041, and the latch 4041 is inserted into the through groove 402.
In order to make the deformation of the mounting plate 401 more reliable, in this embodiment, the through slot 402 is T-shaped, and the middle portion 4021 extends to the edge. The T-shape divides the mounting plate 401 into two by the middle portion 4021, joins the side portions 4022, and defines a side plate 4012 that is easily deformable in the mounting plate 401. The connection is achieved by deforming side plate 4012 as adjustment screw 403 changes the width of middle portion 4021.
Furthermore, in this embodiment, the adjusting screw 403 is disposed in the middle of the through groove 402, and the middle position of the T-shape is at the boundary, where the adjusting screw 403 is disposed, so that the deformation of the entire mounting plate 401 is relatively uniform, and the assembly is more easily standardized.
The adjusting screw 403 is required to have a varying cross-section in order to widen the through-slot 402, in this embodiment the bottom surface of the nut of said adjusting screw 403 is arranged obliquely.
In this embodiment, the width of the side portions 4022 of the through slots 402 increases from the middle to the distal end. This arrangement makes the mounting plate 401 more deformable for assembly.
In this embodiment, the edge of the mounting plate 401 is located at two sides of the middle portion 4021 and is provided with a groove 4011. The setting of recess 4011 can be when mounting disc 401 is dismantled to needs, loosen adjusting screw 403 back again, run through under the unable condition that resumes the not mounted state by oneself of groove 402, can stir mounting disc 401 through recess 4011 and reduce through groove 402, convenient to detach.
In this embodiment, the rotation arm 300 is rotatably connected to the tension mounting part 400. The tension mounting part 400 is used for connecting the rotating arm 300, and the rotating arm 300 is connected to the lamp housing 100 through the tension mounting part with adjustable tightness, so that when the length of the lamp housing 100 is changed, the mounting mode of the rotating arm 300 is kept unchanged, and the universality of parts is improved.
In this embodiment, a heat conducting mounting plate 500 in interference fit is disposed in the lamp housing 100, and the light source assembly 200 is disposed on the heat conducting mounting plate 500. The lamp housing 100 can be simpler in structure, can be manufactured by adopting a tube, and is lower in cost and better in heat dissipation. A power supply 600 is also provided above the thermally conductive mounting plate 500.
In this embodiment, the lamp housing 100 is a tube. The cost is reduced, and the heat dissipation effect is improved. The tail of the lamp housing 100 is also provided with a rear cover 700.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, and any modifications, equivalents or improvements that are within the spirit of the present invention are intended to be covered by the following claims.
