Description

Technical Field

[0001] The utility model relates to the field of lighting lamps, in particular to a lamp housing structure capable of changing the lighting range. Background Technique

[0002] In 1809, the British chemist Davy invented the arc lamp, and humanity entered the era of using electric lighting. In 1879, in the California Theatre in the United States, humans used the arc lamp (electric arc light) for the first time. In 1906, Edison invented the household electric light bulb with a tungsten filament. Since then, incandescent lamps, fluorescent lamps, energy-saving lamps, neon lamps, and various high-tech lamps invented using high technology in contemporary times have emerged like bamboo shoots after a spring rain on the lighting stage, greatly facilitating people's production and life.

[0003] In order to ensure the lighting effect and prevent unnecessary light waste, the existing wall-mounted lamps generally use a bowl-shaped lampshade with a reflective inner wall to cover the light bulb, and the light is reflected to the opening direction of the lampshade through its reflective surface so that the light shines in the same direction, improving the lighting effect.

[0004] However, the lighting range of the existing wall-mounted lamps is relatively fixed. When stronger brightness is required for lighting, it is necessary to replace the lamp beads with higher lumens. When the lighting range needs to be changed, it is necessary to replace the lampshade, which is rather troublesome. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a lamp housing structure capable of changing the lighting range, so as to solve the technical problem that the lighting range of the existing wall-mounted lamps is relatively fixed. When stronger brightness is required for lighting, it is necessary to replace the lamp beads with higher lumens. When the lighting range needs to be changed, it is necessary to replace the lampshade, which is rather troublesome.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A lamp housing structure capable of changing the lighting range, including a housing. A number of openings are provided on the front surface of the housing, and a lampshade is arranged in each opening. A lamp body is movably arranged in each lampshade. A number of sliding columns are arranged on the side wall of the lamp body, and a track groove matching the sliding columns on the corresponding lamp body is provided on the lampshade.

[0007] By adopting the above technical scheme, rotating the lamp body can drive the sliding columns to move along the track groove, thereby driving the lamp body to contract, and cooperating with the lampshade to change the lighting range and intensity of the lamp body.

[0008] The utility model is further arranged such that the track groove is L-shaped, the vertical side of the track groove is inclined outward, and the inner corner of the track groove is arc-shaped.

[0009] By adopting the above technical solution, the vertical sides of the track groove are inclined outward, which facilitates the movement of the sliding column along the track groove. The inner corner of the track groove is arc-shaped to facilitate the change of the moving direction of the sliding column and guide it.

[0010] The present utility model is further configured such that an inner shell is wrapped around the outside of the lamp body within the outer shell, and a clamping block cooperating with the inner shell is provided on the side wall of the lamp body.

[0011] By adopting the above technical solution, the inner shell fixed to the lamp body by the clamping block can protect the lamp body.

[0012] The present utility model is further configured such that a back plate is snap-fitted to the back surface of the outer shell, and a gourd-shaped hanging hole is formed on the back surface of the back plate.

[0013] By adopting the above technical solution, the hanging hole can be used for hanging the device.

[0014] The present utility model is further configured such that wire managers are provided on both the lamp body and the back plate, and the wire managers are made of rubber.

[0015] By adopting the above technical solution, the wire managers can be used to bundle wires, and the fact that the wire managers are made of rubber can better protect the wires.

[0016] The present utility model is further configured such that a circuit board cooperating with the lamp body is provided inside the outer shell.

[0017] By adopting the above technical solution, the electronic control board can control the lighting and extinguishing of the lamp body.

[0018] The present utility model is further configured such that a flat cut surface cooperating with the outer shell is provided on the outer edge of the lamp cover, and the inner wall of the lamp cover is a bright surface reflection layer.

[0019] By adopting the above technical solution, the flat cut surface can fix the lamp cover to prevent the lamp cover from rotating, and the bright surface reflection layer of the lamp cover can reflect light to make the light more concentrated.

[0020] In summary, the present utility model mainly has the following beneficial effects:

[0021] In the present utility model, the lamp body and the lamp cover are set in a separated state. A sliding column and a track groove for restricting movement are respectively provided on the lamp body and the lamp cover. By restricting the telescopic movement of the lamp body through the sliding column and the track groove and controlling the relative distance between the lamp body and the lamp cover, the lighting range can be converged by the lamp cover, and it is convenient to control the lighting range and brightness of the lamp body as needed.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0029] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0030] A lamp shell structure capable of changing the illumination range, as Figures 1-5 shown, includes an outer shell 1. A plurality of openings are provided on the front surface of the outer shell 1, and a lamp shade 2 is provided in each opening. A lamp body 3 is movably arranged in each lamp shade 2. A plurality of sliding columns 6 are arranged on the side wall of the lamp body 3, and a track groove 7 matching with the sliding columns 6 on the corresponding lamp body 3 is provided on the lamp shade 2. The track groove 7 is L-shaped, the vertical side of the track groove 7 is inclined outward, and the inner corner of the track groove 7 is arc-shaped. By rotating the lamp body 3, the sliding columns 6 move along the track groove 7, driving the lamp body 3 to contract into the lamp shade 2. The inner wall of the lamp shade 2 is a bright surface reflection layer, so that the lamp shade 2 can better converge the illumination range of the lamp body 3 and make the illumination more concentrated, and the illumination intensity at the illumination position is higher.

[0031] Among them, an inner shell 4 is wrapped outside the lamp body 3 in the outer shell 1 and is clamped with it through a clamping block 8, which can further protect the lamp body 3.

[0032] In order to facilitate the fixing of the device, a back plate 5 is clamped on the back surface of the outer shell 1, and a gourd-shaped hanging hole 10 is provided on the back surface of the back plate 5. During use, the larger end of the hanging hole 10 is sleeved on the hook, and then the hook is slid to the smaller end of the hanging hole 10, and the fixing of the device can be completed, and the device is not easy to fall off.

[0033] A circuit board matching with the lamp body 3 is arranged inside the outer shell 1, so that the lamp body 3 can be intelligently controlled through the circuit board.

[0034] Both the lamp body 3 and the back plate 5 are provided with wire managers 9, and the wire manager 9 is made of rubber. The wire manager 9 made of rubber can better protect the lamp body 3 and the wires led out from the circuit board, preventing the wires from being damaged due to long-term friction with hard materials.

[0035] In order to prevent the lamp body 3 from driving the lamp cover 2 to rotate synchronously when the lamp body 3 rotates, so that the sliding column 6 cannot move along the track groove 7 to drive the lamp body 3 to expand and contract, a flat cut surface matching with the outer shell 1 is provided at the outer edge of the lamp cover 2 to fix the lamp cover 2.
