Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lighting fixture with a light leakage prevention structure. Background Technology

[0002] A lamp is a device that provides artificial lighting. It mainly consists of a light source, lampshade, lamp holder, and related circuit accessories. Lamps serve multiple purposes. In daily life, they can provide sufficient light for indoor spaces such as homes, offices, and shopping malls, allowing people to clearly see their surroundings and carry out various activities. Existing lamps usually require light leakage prevention designs to concentrate the light and obtain optimal lighting conditions.

[0003] Chinese patent provides a landscape lighting fixture, publication number CN218895319U, which includes a ground socket, a base, a lamp post, and a lamp head mounted on the top of the lamp post. The base is detachably connected to the ground socket. A motion sensor is provided on one side of the lamp head. The lamp post is rotatably mounted on the base. A protrusion is provided on one side of the bottom of the lamp post. A limiting part that cooperates with and abuts against the protrusion is provided inside the base.

[0004] The aforementioned lamps are easy to adjust, but they can only be used for ordinary lighting. When a single lamp needs to illuminate a larger area, it cannot do so. Therefore, a lamp with a light leakage prevention structure is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a lamp with a light leakage prevention structure to solve the problem that existing lamps can only illuminate a fixed area and cannot adjust the illumination range according to the actual usage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lamp with a light leakage prevention structure, comprising a bracket and seven lamp bodies, six of which are located inside the bracket. A fixing plate is fixedly installed inside the bracket, and six connecting rods are movably connected to the outside of the fixing plate. The ends of the six connecting rods are fixedly connected to the six lamp bodies respectively. A threaded rod 1 is provided through the bracket, and a threaded rod 2 is provided inside the threaded rod 1. The threaded rod 2 is fixedly connected to one lamp body.

[0007] Preferably, the seven lamp bodies are hexagonal in shape and have the same size.

[0008] Preferably, the second threaded rod is threadedly connected to the first threaded rod, the first threaded rod passes through the fixing plate, and the first threaded rod is sleeved with both the fixing plate and the bracket.

[0009] Preferably, a limiting ring is provided at the upper outer position of the threaded rod, and the threaded rod and the limiting ring are threadedly connected.

[0010] Preferably, a movable sleeve is fixedly connected to the outside of the threaded rod, and a movable rod is movably connected to the outside of the movable sleeve, with one end of the movable rod being movably connected to the connecting rod.

[0011] Preferably, each of the six lamp bodies located on the outer side is fixedly connected to a connecting block, and a cover is fixedly connected to the outside of the connecting block.

[0012] Preferably, the cover is conical and located outside the seven lamp bodies.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This lamp with a light leakage prevention structure can be used with seven lamps to adjust the illumination range according to the actual use. When local focused lighting is needed, the seven lamps can be adjusted to the same plane for focused lighting. When the illumination range needs to be expanded, pull the threaded rod upward to move the movable sleeve upward. The upward movement of the movable sleeve causes the movable rod to tilt and support the connecting rod, thereby moving the six outer lamps away from the lamp in the middle position, thus achieving the effect of expanding the illumination range.

[0015] 2) This lamp has a light leakage prevention structure. The lamp body in the middle position is equipped with a threaded rod 2. When the six lamp bodies on the outside are far apart, the threaded rod 2 is rotated so that the lamp body can reach the same horizontal height as the lamp bodies on the outside, so that there will be no light leakage. In addition, the outer cover of the lamp body is made of a retractable and foldable material, so there will be no light leakage in the lamp body on the inside. Attached Figure Description

[0021] 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.

[0022] Example 1

[0023] Combination Figure 1 - Figure 4 A lamp with a light leakage prevention structure includes a bracket 1 and seven lamp bodies 6, all of which are located inside the bracket 1.

[0024] See Figure 1 and Figure 2 Furthermore, a fixing plate 4 is fixedly installed on the inner side of the bracket 1. Six connecting rods 5 are movably connected to the outside of the fixing plate 4. The ends of the six connecting rods 5 are fixedly connected to six lamp bodies 6 respectively. A threaded rod 1 2 is provided through the bracket 1. A threaded rod 2 8 is provided inside the threaded rod 1 2. The threaded rod 2 8 is fixedly connected to one lamp body 6. The seven lamp bodies 6 are hexagonal in shape and have the same size. The threaded rod 2 8 is threadedly connected to the threaded rod 1 2. The threaded rod 1 2 passes through the fixing plate 4 and is sleeved with both the fixing plate 4 and the bracket 1. A limit ring 3 is provided at the upper position of the threaded rod 1 2, and the threaded rod 1 2 and the limit ring 3 are threadedly connected. A movable sleeve 9 is fixedly connected to the outside of the threaded rod 1 2. A movable rod 10 is movably connected to the outside of the movable sleeve 9. One end of the movable rod 10 is movably connected to the connecting rod 5.

[0025] Specifically, this lamp can expand its application range according to the specific usage method. When the area to be illuminated needs to be expanded, pull the threaded rod 2 upward. The external movable sleeve 9 moves upward with the threaded rod 2. The upward movement of the movable sleeve 9 drives the movable rod 10 upward, thereby adjusting the angle of the movable rod 10. The adjustment of the angle of the movable rod 10 supports the connecting rod 5. The support of the connecting rod 5 allows the six external lamp bodies 6 to spread outward, thereby allowing the light source to spread and increasing the illumination area. Finally, rotate the limiting ring 3 downward so that the threaded rod 2 will not move downward.

[0026] Example 2

[0027] See Figure 3 and Figure 4 Furthermore, based on Embodiment 1, it is further found that each of the six lamp bodies 6 located on the outside is fixedly connected to a connecting block 7, and a cover 11 is fixedly connected to the outside of the connecting block 7; the cover 11 is in a conical state and is located outside the seven lamp bodies 6.

[0028] Specifically, the outer cover 11 is made of a stretchable and foldable material, so that when the inner lamp body 6 expands, the outer cover 11 can expand according to the expansion angle of the lamp body 6, and when the lamp body 6 is retracted, the outer cover 11 will also retract into a conical state.

[0029] In actual operation, simply turn on the power of the lamp body 6 to illuminate. When it is necessary to expand the lighting range, pull the threaded rod 12 upward and then rotate the limiting ring 3 to fix the height of the threaded rod 12. The threaded rod 12 moves upward, causing the moving sleeve 9 to move upward. The moving sleeve 9 moves upward, causing the movable rod 10 to tilt at an angle. The tilt of the movable rod 10 supports the connecting rod 5. The connecting rod 5 and the fixing plate 4 are rotatably connected, so the connecting rod 5 can expand outward. All six lamp bodies 6 are located at the bottom of the connecting rod 5, so all six lamp bodies 6 can spread outward to achieve the effect of expanding the light source area. The outer cover 11 of the lamp body 6 is made of a retractable and foldable material. Therefore, when the lamp body 6 expands, the outer cover 11 will also expand accordingly, so that the internal light source will not leak light. Finally, rotate the threaded rod 28 so that the lamp body 6 in the middle position can be level with the height of the six outer lamp bodies 6, so that the middle lamp body 6 will not leak light.

[0030] When focusing the light source is required, first rotate the threaded rod 8 to lengthen the lamp body 6 located in the middle position, and finally loosen the limiting ring 3 upwards so that the threaded rod 2 can extend downwards.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
