[0004] The technical solution adopted by this utility model to solve its technical problem is:
[0005] This utility model provides a lamp with an adjustable light emission angle, comprising: a lamp body, the lamp body including a light-emitting element and a first annular groove, the light-emitting element protruding from the outer end face of the lamp body, the end face of the light-emitting element away from the lamp body forming a mounting surface, a portion of the side wall surface of the light-emitting element forming a light-emitting surface, the first annular groove being formed on the outer end face of the lamp body and surrounding the light-emitting element; a connecting pressure plate, the central area of the connecting pressure plate being fixedly connected to the mounting surface of the light-emitting element, a second annular groove being formed on the surface of the connecting pressure plate facing the lamp body, the second annular groove being opposite to the first annular groove; a dimming plate, the two ends of the dimming plate being slidably engaged in the first annular groove and the second annular groove respectively, so that the dimming plate can rotate around the light-emitting element to adjust the light emission range of the dimming plate blocking the light-emitting surface.
[0006] Furthermore, ball bearing assemblies are installed at both ends of the dimming plate, and the spring balls of the ball bearing assemblies are attached to the bottom surfaces of the first annular groove and the second annular groove.
[0007] Furthermore, each of the dimming sheets has two sets of ball bearing assemblies installed at one end.
[0008] Furthermore, a plurality of positioning slots are provided on the bottom surface of the first annular groove or the second annular groove. When the dimming plate rotates to the positioning slot, the spring ball on the dimming plate engages with the positioning slot to position the dimming plate.
[0009] Furthermore, limit stops are provided at the quadrants of both the first and second annular grooves.
[0010] Furthermore, a total of four dimming sheets are configured, and each dimming sheet is independently configured to move between two adjacent limit blocks.
[0011] Furthermore, the light-emitting element is shaped like a cuboid, and the top and bottom sides of the cuboid extend along the centerline region along the axial direction to form the light-emitting surface.
[0012] Furthermore, a positioning pin is provided on the mounting surface of the light-emitting component, and correspondingly, a pin hole that mates with the positioning pin is provided at the center of the connecting pressure plate.
[0013] Furthermore, a raised toggle bar is formed on the outer side of the dimming plate.
[0014] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:
[0015] This utility model discloses an adjustable light-emitting angle lamp, in which a light-emitting element is prominently mounted on the outer end face of the lamp body. The light-emitting surface of the light-emitting element is formed on the side wall of the light-emitting element, meaning that the lamp emits light from the side wall of the light-emitting element. A freely rotatable dimming plate is disposed on the outer periphery of the side wall of the light-emitting element. One end of the dimming plate is slidably fitted in a first annular groove on the outer end face of the lamp body, and the other end of the dimming plate is disposed in a second annular groove of a connecting pressure plate. The connecting pressure plate is fixedly connected to the mounting surface of the light-emitting element away from the lamp body to limit the dimming plate on the lamp body, so that the dimming plate can rotate around the light-emitting element under the action of external force to adjust the light-emitting range of the light-emitting surface blocked by the dimming plate. The way the dimming plate blocks the light-emitting surface is simple and easy for users to understand. The dimming plate is mechanically fitted to the lamp body, which has strong stability. In summary, this utility model of an adjustable light-emitting angle lamp solves the technical problems of difficult operation and poor stability of the existing lamp light-emitting angle adjustable method.
[0016] The adjustable light-emitting angle lamp of this utility model has multiple positioning slots on the bottom surface of the first or second annular groove. When the dimming disc rotates to the positioning slot, the spring ball on the dimming disc engages with the positioning slot to position the dimming disc. The position of the positioning slot allows the dimming disc to stop at a specific position, thereby blocking a certain value of the light-emitting surface's light-emitting range, thus accurately obtaining a specific light-emitting effect, thereby solving the technical problem of inaccurate light-emitting angle positioning in existing lamps.

[0025] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0026] like Figure 1-5As shown, this utility model provides a lamp with an adjustable light emission angle, including a lamp body 1, a connecting pressure plate 2, and a dimming plate 3. The lamp body 1 includes a light-emitting element 11 and a first annular groove 12. The light-emitting element 11 protrudes from the outer end face of the lamp body 1. The end face of the light-emitting element 11 away from the lamp body 1 is formed as a mounting surface 111. A portion of the side wall surface of the light-emitting element 11 is formed as a light-emitting surface 112. The first annular groove 12 is formed on the outer end face of the lamp body 1 and holds the light-emitting element... The central area of the connecting pressure plate 2 is fixedly connected to the mounting surface 111 of the light-emitting element 11. A second annular groove 21 is formed on the surface of the connecting pressure plate 2 facing the lamp body 1. The second annular groove 21 is opposite to the first annular groove 12. The two ends of the dimming disc 3 are slidably engaged in the first annular groove 12 and the second annular groove 21 respectively, so that the dimming disc 3 can rotate around the light-emitting element 11 to adjust the light emission range of the light-emitting surface 112 blocked by the dimming disc 3.
[0027] To facilitate positioning during installation, a positioning pin 113 is provided on the mounting surface 111 of the light-emitting component 11. Correspondingly, a pin hole 23 that mates with the positioning pin 113 is provided at the center of the connecting pressure plate 2.
[0028] In a specific embodiment of this utility model, the connecting pressure plate 2 is fixed to the mounting surface 111 of the light-emitting component 11 by screwing. For example, a threaded hole 24 is opened on the surface of the connecting pressure plate 2 facing the lamp body 1. The bolt 25 that fits in the threaded hole 24 can be screwed from the connecting pressure plate 2 to the lamp body 1. Alternatively, the bolt 25 can be inserted into the lamp body 1 first and then screwed into the connecting pressure plate 2.
[0029] To facilitate the movement of the dimmer 3, a raised actuation strip 32 is formed on the outer side of the dimmer 3.
[0030] To make the rotation of the dimming plate 3 smoother, ball bearing assemblies 31 are installed at both ends of the dimming plate 3. The spring balls of the ball bearing assemblies 31 are attached to the bottom surfaces of the first annular groove 12 and the second annular groove 21.
[0031] Furthermore, each dimming disc 3 is equipped with two sets of ball bearing assemblies 31 at one end, making the rotation of the dimming disc 3 smoother and more stable without jamming.
[0032] In order to make the light output angle more accurate, multiple positioning slots 13 are also provided on the bottom surface of the first annular slide groove 12 or the second annular slide groove 21. When the dimming plate 3 rotates to the positioning slot 13, the spring ball on the dimming plate 3 engages with the positioning slot 13 to position the dimming plate 3.
[0033] Furthermore, limit blocks 22 are provided at the quadrants of the first annular slide 12 and the second annular slide 21. Specifically, the limit blocks 22 located at the upper and lower quadrants of the first annular slide 12 and the second annular slide 21 are designed to be small. The limit blocks 22 at the upper and lower quadrants play a positioning role. After the dimming plate 3 hits the limit block 22, it can achieve a specific light output angle. The limit blocks 22 located at the left and right quadrants of the first annular slide 12 and the second annular slide 21 are designed to be large. This makes the limit blocks 22 form a clearance space on the left and right sides of the light output component 11, so as to facilitate the installation of the lamp. Wiring or other components can be arranged in the clearance space.
[0034] In a preferred embodiment of this utility model, four dimming discs 3 are configured, each of which is independently positioned between two adjacent limiting blocks 22. The light-emitting element 11 is rectangular in shape, and the side top and side bottom surfaces of the rectangular prism extend along the central region along the axial direction to form a light-emitting surface 112. Simultaneously, in this embodiment, three positioning slots 13 are configured between each of the two limiting blocks 22. When the two dimming discs 3 located outside the upper half of the arc of the light-emitting element 11 abut against the limiting block 22 in the upper quadrant, the gap between the two dimming discs 3 is a 20-degree angle, equivalent to a light emission angle of 20 degrees for the lamp. When the spring balls of the two dimming discs 3 enter the three symmetrical positioning slots 13, the light emission angles of the lamp correspond to 80 degrees, 100 degrees, and 120 degrees, thus accurately achieving the adjustment of several specific light emission angles.
[0035] It should be understood that the specific embodiments described above are only for explaining the present invention and are not intended to limit the present invention. Obvious variations or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
