Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to lighting fixtures with an adjustable light source structure. Background Technology

[0002] Lighting fixtures are devices that have the functions of transmitting, distributing, and changing the light distribution of a light source. Their components include not only all the necessary parts for fixing and protecting the light source, except for the light source itself, but also the wiring accessories that are indispensable when connected to the power supply. They are the core supporting devices for achieving stable, safe, and efficient light emission from the light source.

[0003] Most existing lighting fixtures have relatively fixed structures, resulting in a narrow illumination range, which makes it difficult to meet the lighting needs of large spaces and easily leads to uneven brightness. At the same time, most ordinary lighting fixtures have fixed brightness and color temperature, which cannot be flexibly adjusted according to the scene and lack personalized experience.

[0004] Therefore, considering that most of the above-mentioned lamps have relatively fixed structures, resulting in a narrow illumination range, making it difficult to meet the lighting needs of large areas and easily causing uneven brightness, and that ordinary lamps mostly have fixed brightness and color temperature, which cannot be flexibly adjusted according to the scene and lack personalized experience, lamps with adjustable light source structures can be designed. Utility Model Content

[0005] To overcome the problems that most lamps have relatively fixed structures, resulting in narrow illumination ranges that are difficult to meet the lighting needs of large spaces and uneven brightness, and that ordinary lamps have fixed brightness and color temperature that cannot be flexibly adjusted according to the scene and lack personalized experience, a lamp with an adjustable light source structure is proposed.

[0006] The technical solution of this utility model is as follows: a lamp with an adjustable light source structure, including a lamp holder; a lamp cover is installed on the top of the lamp holder, and an adjustment component for adjusting the angle of the lamp is installed at the rear end of the lamp cover. The adjustment component includes a fixing frame, which is bolted to the bottom of the rear side of the lamp cover. A mounting frame is bolted to the outside of the fixing frame, and a rotating rubber ring is symmetrically arranged at the center of the rear side wall of the mounting frame.

[0007] Preferably, a connecting rod is installed inside the rotating rubber ring, and the mounting bracket is rotatably connected to the outside of the connecting rod. A movable frame is provided at the rear end of the connecting rod, and a rubber ring is provided inside the movable frame.

[0008] Preferably, the left side of the movable frame is provided with an adjustment rod with a handle, and the right side of the adjustment rod is located inside the movable frame.

[0009] Preferably, a connecting rod is provided at the bottom of the movable frame one, and the connecting rod is rotatably connected to the connecting rod through the movable frame one, and a movable frame two is provided at the bottom of the connecting rod.

[0010] Preferably, the right side of the movable frame two is provided with an adjustment rod two with a handle, and a support rod is fixedly connected to the middle position of the top of the lamp holder, and the connecting rod is rotatably connected to the support rod through the movable frame two.

[0011] Preferably, the lampshade has heat dissipation holes on the rear side inside, and the heat dissipation holes are symmetrically arranged in the center.

[0012] Preferably, an adjustment button is provided at the middle position of the top of the lamp holder, and a placement box is provided on one side of the top of the lamp holder.

[0013] The beneficial effects of this utility model are as follows: The fixing bracket is installed at the bottom of the back side of the lampshade by bolts, and the mounting bracket is connected to the outside of the fixing bracket by bolts, connecting the fixing bracket to the rotating rubber ring. The rotating rubber rings, which are symmetrically arranged at the center of the rear side wall of the mounting bracket, can drive the associated lamp source components to rotate at multiple angles when the illumination direction of the light source needs to be adjusted, by utilizing the elasticity and rotatability of the rotating rubber rings. This changes the projection angle of the light, meets the needs of the illumination direction in different scenarios, and ensures the stability of the entire adjustable structure during use. It will not loosen or shake due to adjustment operations or long-term use, thus ensuring the service life and safety of the lamp. Attached Figure Description

[0020] Please see Figures 1-5This utility model provides an embodiment of a lamp with an adjustable light source structure, including a lamp holder 1; a lamp cover 2 is installed on the top of the lamp holder 1, and an adjustment component for adjusting the angle of the lamp is installed at the rear end of the lamp cover 2. The adjustment component includes a fixing frame 501, which is bolted to the bottom of the rear side of the lamp cover 2. A mounting frame 502 is bolted to the outside of the fixing frame 501. Rotating rubber rings 503 are symmetrically arranged at the center of the rear side wall of the mounting frame 502. An adjustment button 3 is provided at the middle position of the top of the lamp holder 1, and a placement box 4 is provided on one side of the top of the lamp holder 1.

[0021] Please see Figures 2-3 In this embodiment, a connecting rod 504 is installed inside the rotating rubber ring 503, and the mounting bracket 502 is rotatably connected to the outside of the connecting rod 504. A movable frame 505 is provided at the rear end of the connecting rod 504, and a rubber ring is provided inside the movable frame 505. An adjusting rod 506 with a handle is provided on the left side of the movable frame 505, and the right side of the adjusting rod 506 is provided inside the movable frame 505. A connecting rod 507 is provided at the bottom end of the movable frame 505, and the connecting rod 504 is rotatably connected to the connecting rod 507 through the movable frame 505. A movable frame 508 is provided at the bottom end of the connecting rod 507.

[0022] Rotating the rubber ring 503 can drive the connecting rod 504 and the mounting bracket 502 to rotate. The cooperation between the movable bracket 1 505, the connecting rod 507, and the movable bracket 2 508 can realize the multi-dimensional and multi-angle adjustment of the light source to meet the needs of the light direction in different scenarios.

[0023] The adjustment rod 506 features a handle, allowing users to easily control the state of the movable frame 505 by rotating or pushing the handle, thereby adjusting the light source position. The operation is simple and intuitive, requiring no complex tools. The movable frame 505 has an internal rubber ring, enhancing friction and stability at the connection points and reducing the likelihood of the light source shifting due to external forces after adjustment, ensuring accurate lighting position. Because the light source is flexibly adjustable, this luminaire can be used in both work areas requiring concentrated lighting and leisure areas requiring diffused lighting, enhancing its versatility. Adjustment is achieved through rotating connections between components, reducing wear and damage from rigid connections. Simultaneously, the rubber ring and other components provide cushioning, minimizing wear and tear on the luminaire during adjustment and extending its overall lifespan.

[0024] Please see Figures 4-5In this embodiment, a connecting rod 507 is provided at the bottom end of the movable frame 505, and a connecting rod 504 is rotatably connected to the connecting rod 507 through the movable frame 505. A movable frame 508 is provided at the bottom end of the connecting rod 507. An adjusting rod 509 with a handle is provided on the right side of the movable frame 508. A support rod 510 is fixedly connected to the middle position of the top of the lamp holder 1, and the connecting rod 507 is rotatably connected to the support rod 510 through the movable frame 508. A heat dissipation hole 511 is provided inside the rear side of the lamp cover 2, and the heat dissipation holes 511 are symmetrically arranged in the center.

[0025] Through the rotating connection structure of movable frame 1 505, connecting rod 507, and movable frame 2 508, combined with the adjusting rod 2 509 with a handle, the angle of the light source can be adjusted in multiple directions. The adjusting rod 2 509 has a handle and is ergonomically designed, allowing users to easily adjust the position of the light source directly by hand without the need for tools. The rotating connection structure of the movable frame and connecting rod 507 is highly stable and can maintain a fixed angle after adjustment, preventing the light source from shifting due to slight touch and ensuring accurate lighting position. The lamp cover 2 has centrally symmetrical heat dissipation holes 511 on the rear interior, which can quickly dissipate the heat generated during lamp operation, reduce heat accumulation in the lamp cover 2, effectively reduce the operating temperature of the lamp beads and circuit components, prevent performance degradation or damage due to overheating, extend the life of the lamp, and reduce safety hazards. The support rod 510 is fixedly connected to the top of the lamp holder 1 as an overall support structure. Together with the rotating connection of movable frame 1 505, movable frame 2 508, and connecting rod 507, it ensures the overall stability of the lamp while maintaining the flexibility of adjustment, reducing the risk of shaking or tipping.

[0026] By pressing the adjustment button 3 at the top center of lamp holder 1, the lamp is turned on, and the light source inside lampshade 2 illuminates, entering the working state. When the angle of the light source needs to be adjusted, hold the adjustment rod 506 with a handle on the left side of movable frame 505 and loosen it in a specific direction. This loosens the rubber ring inside movable frame 505, which fixes the connection between connecting rod 507 and connecting rod 504. Since mounting frame 502 is fitted onto the outside of connecting rod 504 by rotating rubber ring 503, and connecting rod 504 is rotatably connected to connecting rod 507 through movable frame 505, lampshade 2 can be pushed to rotate around the axis of connecting rod 504, adjusting the illumination direction of the light source. When lampshade 2 rotates to the target angle, rotate the handle of adjustment rod 506 in the opposite direction to tighten the rubber ring inside movable frame 505 on its right side. This fixes the relative position of connecting rod 504 and connecting rod 507 through friction, completing the angle locking in this dimension. Hold the right side of movable frame 508. Adjusting rod 509 with handle can be loosened in a specific direction, causing movable frame 508 to loosen its fixation on the connection between connecting rod 507 and support rod 510. Connecting rod 507 is rotatably connected to support rod 510 on lamp holder 1 through movable frame 508. At this time, the lamp cover 2 and connecting rod 507 as a whole can be pushed to rotate around the axis of support rod 510, further adjusting the illumination angle of the light source. After adjusting to a suitable angle, the handle of adjusting rod 509 is rotated in the opposite direction, causing movable frame 508 to tighten its fixation on the connection between connecting rod 507 and support rod 510. The angle in this dimension is locked by friction. The brightness of the light source can be adjusted by adjusting button 3 on the top of lamp holder 1. The storage box 4 on one side of the top of lamp holder 1 can be used to store small items. When the lamp is working, the heat generated by the light source is naturally dissipated through the heat dissipation holes 511 symmetrically opened in the center of the rear of the lamp cover 2, reducing the heat accumulation inside the lamp cover 2, ensuring the stable operation of the light source and lamp components, and extending the service life.
