Description

Technical Field

[0001] This utility model relates to the field of LED lighting fixtures, and in particular to LED lighting fixtures with bidirectional projection function. Background Technology

[0002] LED lights are lighting devices that use semiconductor light-emitting diodes as the light source. They have significant advantages such as high efficiency, energy saving, environmental protection, and long lifespan, and are widely used in the modern lighting field.

[0003] With the rapid development of LED lighting technology, the angle adjustment function of lamps has become the key to improving the flexibility of lighting. At present, bidirectional projection LED lamps on the market can only illuminate in one direction. In addition, LED lamps require an external driving device when rotating, and the lack of an effective linkage mechanism makes it difficult to synchronize the rotation of lamps, resulting in chaotic overall lighting effects and failing to meet the needs of diverse scenarios. In order to solve the above problems, we propose LED lamps with bidirectional projection function. Utility Model Content

[0004] The main purpose of this utility model is to provide an LED lamp with bidirectional projection function, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An LED lamp with bidirectional projection function includes a mounting plate. A toothed ring is fixedly connected to the lower end of the mounting plate. Multiple rotating posts are rotatably connected to the lower end of the mounting plate on the inner side of the toothed ring. The lower ends of the multiple rotating posts are fixedly connected to a rotating mounting base. A first LED lamp and a second LED lamp are movably mounted on the lower end of the rotating mounting base. The first LED lamp and the second LED lamp are spaced apart.

[0007] Preferably, a starter motor is fixedly mounted on the lower end of the rotary mounting base, and a first gear is fixedly connected to the output end of the starter motor. A first rack and a second rack mesh on the outer side of the first gear, and both the first rack and the second rack are slidably connected to the rotary mounting base.

[0008] Preferably, the upper ends of the first LED lamp and the second LED lamp are both fixedly connected with snap-fit ​​blocks. The first LED lamp is engaged with the lower end of the first rack through the corresponding snap-fit ​​blocks, and the second LED lamp is engaged with the lower end of the second rack through the corresponding snap-fit ​​blocks. Rotary bearings are rotatably connected to the outer sides of the two snap-fit ​​blocks, and the rotary bearings are fixedly installed at the lower end of the rotary mounting base.

[0009] Preferably, a rotating rod is fixedly connected to the upper end of the first gear, a driving wheel is fixedly connected to the outer side of the rotating rod, a belt is sleeved on the outer side of the driving wheel, a driven wheel is sleeved on the inner side of the other end of the belt, and the lower end of the driven wheel is rotatably mounted on the upper end of the rotary mounting base.

[0011] Preferably, the lower end of the mounting plate is provided with a sliding groove, and a plurality of rotating columns are provided on the inner side of the sliding groove through a limiting component.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This LED lamp with bidirectional projection function drives the first gear to rotate through the output end of the starter motor, which in turn drives the first rack and the second rack to move relative to or away from each other. The first LED lamp and the second LED lamp are respectively engaged with the corresponding rack through the snap-fit ​​block, and the presence of the rotating bearing on the outside of the snap-fit ​​block allows the two LED lamps to accurately follow the rack sliding, thereby flexibly adjusting the bidirectional projection angle and greatly improving the flexibility of lighting.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5 As shown, an LED lamp with bidirectional projection function includes a mounting plate 1. A toothed ring 2 is fixedly connected to the lower end of the mounting plate 1. Multiple rotating posts 3 are rotatably connected to the lower end of the mounting plate 1 on the inner side of the toothed ring 2. The lower ends of the multiple rotating posts 3 are fixedly connected to a rotating mounting base 5. A first LED lamp 6 and a second LED lamp 7 are movably mounted on the lower end of the rotating mounting base 5. The first LED lamp 6 and the second LED lamp 7 are spaced apart.

[0023] In this embodiment, a starter motor 8 is fixedly installed at the lower end of the rotary mounting base 5. A first gear 9 is fixedly connected to the output end of the starter motor 8. A first rack 11 and a second rack 12 are meshed on the outer side of the first gear 9. Both the first rack 11 and the second rack 12 are slidably connected to the rotary mounting base 5. A snap-fit ​​block 13 is fixedly connected to the upper end of the first LED lamp 6 and the second LED lamp 7. The first LED lamp 6 is meshed with the lower end of the first rack 11 through the corresponding snap-fit ​​block 13, and the second LED lamp 7 is meshed with the lower end of the second rack 12 through the corresponding snap-fit ​​block 13. A rotating bearing 14 is rotatably connected to the outer side of both snap-fit ​​blocks 13. The rotating bearing 14 is fixedly installed at the lower end of the rotary mounting base 5.

[0024] Specifically, after fixing the lamp to the target position using the mounting plate 1, the motor 8 is started, and its output end drives the first gear 9 to rotate. Since the first gear 9 meshes with the first rack 11 and the second rack 12, and both racks are slidably connected to the rotating mounting base 5, when the first gear 9 rotates, it can drive the first rack 11 and the second rack 12 to move relative to or away from each other on the rotating mounting base 5. The first LED lamp 6 and the second LED lamp 7 are respectively meshed with the first rack 11 and the second rack 12 through the snap-fit ​​block 13. The rotating bearing 14 on the outside of the snap-fit ​​block 13 is fixed to the lower end of the rotating mounting base 5, so that the two LED lamps can slide with the racks to adjust the bidirectional projection angle.

[0025] In this embodiment, a rotating rod 10 is fixedly connected to the upper end of the first gear 9, a driving wheel 16 is fixedly connected to the outer side of the rotating rod 10, a belt 17 is sleeved on the outer side of the driving wheel 16, a driven wheel 18 is sleeved on the inner side of the other end of the belt 17, the lower end of the driven wheel 18 rotates away from the upper end of the rotary mounting base 5, and a second gear 19 meshes with the inner side of the gear ring 2. The second gear 19 is fixedly connected to the upper end of the driven wheel 18.

[0026] Specifically, while the first gear 9 rotates, it also drives the rotating rod 10 to rotate. Through the transmission cooperation of the driving wheel 16, belt 17 and driven wheel 18, and the second gear 19 meshing with the inner side of the gear ring 2, the first LED lamp 6 and the second LED lamp 7 can rotate around the center of the gear ring 2 while adjusting the projection angle, so as to achieve all-round projection angle adjustment and meet diverse lighting needs.

[0027] In this embodiment, a groove 4 is provided at the lower end of the mounting plate 1, and multiple rotating columns 3 are provided on the inner side of the groove 4 through a limiting component.

[0028] Specifically, the rotating column 3 slides into the groove 4 at the lower end of the mounting plate 1 to ensure the stable rotation of the rotating mounting base 5, and the limiting component at the upper end of the rotating column 3 can effectively prevent the rotating column 3 from disengaging from the groove 4, thus avoiding safety accidents.

[0029] It should be noted that this utility model is an LED lamp with bidirectional projection function. After the lamp is fixed to the target position by the mounting plate 1, the motor 8 is started, and its output end drives the first gear 9 to rotate. Since the first gear 9 meshes with the first rack 11 and the second rack 12, and both racks are slidably connected to the rotating mounting base 5, when the first gear 9 rotates, it can drive the first rack 11 and the second rack 12 to move relative to or away from each other on the rotating mounting base 5. The first LED lamp 6 and the second LED lamp 7 respectively mesh with the first rack 11 and the second rack 12 through the snap-fit ​​block 13. The rotating bearing 14 on the outside of the snap-fit ​​block 13 is fixed to the rotating mounting base. At the lower end of 5, the two LED lamps can slide with the rack to adjust the bidirectional projection angle. At the same time, the rotation of the first gear 9 will drive the rotating rod 10 to rotate. Through the transmission cooperation of the driving wheel 16, belt 17 and driven wheel 18, and the second gear 19 meshing with the inner side of the gear ring 2, the first LED lamp 6 and the second LED lamp 7 can rotate around the center of the gear ring 2 while adjusting the projection angle, realizing all-round projection angle adjustment to meet diverse lighting needs. In addition, the rotating column 3 slides with the slide groove 4 at the lower end of the mounting plate 1 to ensure the stable rotation of the rotating mounting base 5. The limiting component at the upper end of the rotating column 3 prevents the rotating column 3 from disengaging from the slide groove 4, avoiding safety accidents, which is quite practical.
