Description

Technical Field

[0001] This utility model belongs to the field of lighting fixtures, and specifically relates to a telescopic adjustable lighting fixture structure. Background Technology

[0002] A luminaire is a device used to provide illumination, converting electrical energy or other energy sources into light energy. It is widely used in homes, businesses, industries, and public places. The basic function of a luminaire is to provide sufficient light to meet visual needs, and it can also achieve decorative or ambiance-creating effects through design. However, luminaires without focus adjustment have some obvious drawbacks. The optical system of a fixed-focus luminaire has its beam angle predetermined at the factory and cannot be dynamically adjusted during use. Therefore, it may exhibit significant mismatches under different lighting environments and needs. For example, in scenarios requiring precise focusing, a luminaire with a fixed floodlight design cannot concentrate the light, resulting in insufficient brightness in the target area. Simultaneously, excess light is scattered into surrounding non-critical areas, causing light pollution and energy waste. Conversely, if the luminaire is designed with a narrow beam angle, it will result in insufficient illumination coverage, a small light spot, and strong contrast between light and dark edges, affecting visual comfort and work efficiency. Therefore, we aim to design a telescopic adjustable luminaire structure to solve this problem. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a telescopic adjustable lamp structure to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a telescopic adjustable lamp structure, comprising: a lamp module, wherein a light source assembly is provided at the upper internal end of the lamp module, a telescopic mechanism for adjusting the lighting position of the lamp is provided at the upper external end of the lamp module, and an adjustment mechanism for changing the lighting mode is provided inside the lamp module;

[0005] The adjustment mechanism includes a fixed sleeve that is slidably fitted inside the lamp module. A concave lens is fixedly connected to the inner side of the fixed sleeve. An adjustment cylinder is screwed into the lower end of the lamp module by a thread. A convex lens is fixedly connected inside the adjustment cylinder. By setting the adjustment mechanism, the convex lens can be moved to achieve converging and floodlight modes.

[0006] In a preferred embodiment, both the concave lens and the convex lens are optical glass structures with high light transmittance and high temperature resistance.

[0007] In a preferred embodiment, the fixing sleeve has slots on both the left and right sides for mounting and positioning, and the lamp module has through holes on both the left and right sides.

[0008] In a preferred embodiment, the adjustment mechanism further includes two support frames, which are fixedly connected to the left and right sides of the lighting module. Each support frame has a sliding insert rod inside. The end of the insert rod near the center of the lighting module slides through a through hole into the interior of the lighting module, and the extended end is fitted into the slot of the fixing sleeve. The cooperation between the insert rod and the slot on the fixing sleeve facilitates quick disassembly of the fixing sleeve and the concave lens, which is convenient for subsequent maintenance of the lighting module.

[0009] In a preferred embodiment, a collar is fixedly sleeved on the outer side of the insertion rod, and the collar is elastically connected to the inner surface of the support frame by a spring, so that the insertion rod is kept inside the fixed sleeve by the elastic force of the spring.

[0010] In a preferred embodiment, the telescopic mechanism includes a base, and one end of an adjusting rod is movably connected to the inner side of the base via a damping pivot. The other end of the adjusting rod is also connected to an adjusting rod two via a damping pivot. A connecting block is fixedly connected to the lower side of the adjusting rod two, and the connecting block is fixedly connected to the upper end of the lighting module. By setting up the telescopic mechanism, it is suitable for scenarios requiring fine lighting, while improving the coverage of the light source.

[0011] As a preferred embodiment, the base is a high-density, heavy cast iron structure that provides stability.

[0012] In a preferred embodiment, the lower surface of the base is provided with a rubber pad to increase the friction of its lower surface.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] By setting an adjustment mechanism, the concave lens provides basic flooding. The concave lens first diffuses the light, so that the light evenly covers the surface of the convex lens, making the light transition smoother and eliminating the phenomenon of excessively bright central spot that is common when using a convex lens directly. Then, the convex lens is adjusted a second time. The adjustment cylinder causes the convex lens to move closer to or away from the light source, so as to achieve the beam convergence and flooding modes.

[0015] By setting up a telescopic mechanism, the illumination position of the lighting module can be adjusted, making it suitable for scenarios requiring fine lighting while increasing the coverage of the light source. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 3 as well as Figure 4 As the first embodiment of this utility model:

[0026] A telescopic adjustable lighting fixture structure includes: a lighting fixture module 1, a light source assembly is provided at the upper internal end of the lighting fixture module 1, a telescopic mechanism 2 for adjusting the lighting position of the lighting fixture is provided at the upper external end of the lighting fixture module 1, and an adjustment mechanism 3 for changing the lighting mode is provided inside the lighting fixture module 1.

[0027] The adjustment mechanism 3 includes a fixed sleeve 31, which is slidably fitted inside the lamp module 1. A concave lens 32 is fixedly connected to the inner side of the fixed sleeve 31. An adjustment cylinder 33 is screwed into the lower end of the lamp module 1 through a thread. A convex lens 34 is fixedly connected inside the adjustment cylinder 33. By setting the adjustment mechanism 3, the convex lens 34 can be moved to achieve the focusing and floodlight modes.

[0028] Both the concave lens 32 and the convex lens 34 are optical glass structures with high light transmittance and high temperature resistance.

[0029] The fixing sleeve 31 has slots 311 on both the left and right sides for mounting and positioning, and the lamp module 1 has through holes on both the left and right sides.

[0030] The adjustment mechanism 3 also includes two support frames 35, which are fixedly connected to the left and right sides of the lighting module 1. Each of the two support frames 35 has a sliding insert rod 36 inside. The end of the insert rod 36 near the center of the lighting module 1 slides through the through hole into the interior of the lighting module 1, and the extended end is fitted into the slot 311 of the fixing sleeve 31. The cooperation between the insert rod 36 and the slot 311 on the fixing sleeve 31 facilitates the quick disassembly of the fixing sleeve 31 and the concave lens 32, which is convenient for subsequent maintenance of the lighting module 1.

[0031] A collar 37 is fixedly sleeved on the outer side of the insertion rod 36. The collar 37 is elastically connected to the inner surface of the support frame 35 by a spring 38. The elastic force of the spring 38 keeps the insertion rod 36 inside the fixed sleeve 31.

[0032] Specifically, during use, when it is necessary to switch the light mode, first rotate the adjusting cylinder 33. The adjusting cylinder 33 further drives the convex lens 34 to move up and down, thereby changing the relative distance between the convex lens 34 and the light source and the imaging surface, thus dynamically adjusting the convergence or divergence of the output light. When the convex lens 34 is close to the light source, the effective focal length is shortened and the beam angle becomes smaller in the focusing mode. Conversely, when the convex lens 34 is far away from the light source, the effective focal length is extended and the beam angle expands in the floodlight mode. At the same time, when it is necessary to maintain the lamp module 1, it can be removed by rotating the adjusting cylinder 33, and then the plug rod 36 can be pulled to separate it from the fixing sleeve 31, thereby realizing quick disassembly of the fixing sleeve 31 and the concave lens 32, which facilitates the maintenance of the light source components inside the lamp module 1.

[0033] Please see Figure 1 as well as Figure 2As a second embodiment of this utility model: based on the description in the above embodiments, the telescopic mechanism 2 further includes a base 21. One end of an adjusting rod 22 is movably connected to the inner side of the base 21 via a damping pivot. The other end of the adjusting rod 22 is also connected to an adjusting rod 23 via a damping pivot. A connecting block 24 is fixedly connected to the lower side of the adjusting rod 23. The connecting block 24 is fixedly connected to the upper end of the lighting module 1. By setting the telescopic mechanism 2, it is suitable for scenarios that require fine lighting, while improving the coverage of the light source.

[0034] The base 21 is a high-density and heavy cast iron structure that provides stability. Even if the center of gravity shifts due to the extension and retraction adjustment of the lamp module 1, it can still use its own weight to keep the whole device stable.

[0035] The lower surface of the base 21 is provided with a rubber pad to increase the friction of its lower surface.

[0036] Specifically, during use, when it is necessary to adjust the position of the lamp module 1, first pull or push the adjustment rod 23 to rotate it and place the lamp module 1 in the desired illumination position for fine lighting. During the pulling or pushing of the adjustment rod 23, the damping shaft connection end of the adjustment rod 23 and the adjustment rod 1 22 rotates. At the same time, the adjustment rod 23 drives the adjustment rod 1 22 to rotate around the damping shaft inside the base 21. The damper generates resistance inside the shaft to prevent the lamp from being accidentally displaced.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
