Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a floodlight. Background Technology

[0002] Traditional low-mounted floodlights can easily shine directly into people's eyes (such as pedestrians and drivers), producing strong glare that causes visual discomfort or safety hazards. A common solution is to install a baffle plate above the light-emitting end of the floodlight to reduce glare. However, this baffle plate covers the light-emitting end of the floodlight, preventing rainwater from directly washing over the glass and easily accumulating dust, bird droppings, pollen, and other contaminants, thus affecting the light output. Furthermore, the need for an additional baffle plate complicates the lamp's structure and increases costs. Utility Model Content

[0003] The purpose of this invention is to provide a floodlight that effectively prevents glare and dust accumulation, and allows for precise adjustment of the illumination angle.

[0004] To achieve the above objectives, this utility model provides a floodlight, including a lamp barrel, a light source assembly, and a mounting bracket. The light source assembly is disposed on the inner cavity of the lamp barrel and is parallel to the bottom surface of the lamp barrel. The light-emitting end face of the lamp barrel is inclined from top to bottom toward the side close to the light source assembly. A light-transmitting glass is sealed on the light-emitting end face of the lamp barrel. An angle is formed between the plane of the light-emitting end face of the lamp barrel and the plane of the light source assembly. The mounting bracket includes a connecting frame and a mounting base. The connecting frame is disposed at the bottom of the lamp barrel and is rotatably connected to the mounting base. The connecting frame is provided with a first end face gear, and the mounting base is provided with a second end face gear that meshes with the first end face gear. The connecting frame is provided with a first connecting hole, and the mounting base is provided with a second connecting through hole. An adjusting bolt passes through the second connecting through hole and is threadedly connected to the first connecting hole.

[0005] As a preferred embodiment of this utility model, the bottom of the connecting frame is provided with a first rotating part, the first end face gear is provided on one side of the first rotating part, the upper part of the mounting base is provided with a second rotating part, the second end face gear is provided on one side of the second rotating part, the other side of the first rotating part is provided with a first angle scale value, and the mounting base is provided with a first angle indicator mark for indicating the first angle scale value.

[0006] As a preferred embodiment of this utility model, a second angle scale value is provided on the other side of the second rotating part, and a second angle indicator is provided on the connecting frame for indicating the second angle scale value.

[0007] As a preferred embodiment of this utility model, the bottom of the first rotating part is semi-circular, and the mounting base is provided with an arc-shaped surface that rotatably engages with the bottom of the first rotating part; the top of the second rotating part is semi-circular, and the connecting frame is provided with an arc-shaped surface that rotatably engages with the top of the second rotating part.

[0008] As a preferred embodiment of this utility model, the mounting base further includes two semi-circular clamps, which are fixed together by bolts, and the second rotating part is disposed on one of the semi-circular clamps.

[0009] As a preferred embodiment of this utility model, a heat sink is provided inside the cavity of the lamp tube, and the heat sink is located at the bottom of the light source assembly.

[0010] As a preferred embodiment of this utility model, the diameter of the lamp tube gradually decreases from the bottom to the top of the lamp tube.

[0011] As a preferred embodiment of this utility model, the light source assembly includes a lamp bead plate, a lens, and a lens barrel frame. The lens is arranged one-to-one with the lamp beads on the lamp bead plate. The top surface of the lens is provided with a plurality of anti-glare grooves at intervals. The lens barrel frame is provided with a light-transmitting cylinder that is arranged one-to-one with the lens. The light-transmitting cylinder is cylindrical.

[0012] Compared with the prior art, the floodlight of this utility model embodiment has the following advantages:

[0013] In this invention, the light-emitting end face of the lamp tube is inclined from top to bottom towards the side closest to the light source assembly. This makes the upper length of the light-emitting end of the lamp tube longer than the lower length, thus forming a light-blocking structure at the upper part of the light-emitting end. When the floodlight is installed at a low position, it blocks the light source from directly entering the viewer's field of vision, avoiding discomfort or safety hazards caused by strong light stimulation. No external baffle is required. At the same time, the inclined light-transmitting glass can reduce dust accumulation on the horizontal surface, and rainwater can naturally wash away dust, preventing dust accumulation and ensuring good light output efficiency. The angle adjustment is stepless and smooth by loosening the adjusting bolt, and there is no springback after the adjusting bolt is tightened, making the overall structure stable.

Detailed Implementation

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] like Figures 1 to 3 As shown, a floodlight according to a preferred embodiment of the present invention includes a lamp barrel 1, a light source assembly 2, and a mounting bracket 3. The light source assembly 2 is disposed on the inner cavity of the lamp barrel 1 and is parallel to the bottom surface of the lamp barrel 1. The light-emitting end face 11 of the lamp barrel is inclined from top to bottom toward the side close to the light source assembly 2. A light-transmitting glass is sealed on the light-emitting end face 11 of the lamp barrel. An angle is formed between the plane of the light-emitting end face 11 of the lamp barrel and the plane of the light source assembly 2. The mounting bracket 3 includes a connecting frame 31 and a mounting base 32. The connecting frame 31 is disposed at the bottom of the lamp barrel 1 and is rotatably connected to the mounting base 32. The connecting frame 31 is provided with a first end face gear 311, and the mounting base 32 is provided with a second end face gear 321 that meshes with the first end face gear 311. The connecting frame 31 is provided with a first connecting hole, and the mounting base 32 is provided with a second connecting through hole. An adjusting bolt passes through the second connecting through hole and is threadedly connected to the first connecting hole.

[0022] In this invention, the light-emitting end face 11 of the lamp tube is inclined from top to bottom toward the side closest to the light source assembly 2. This makes the upper length of the light-emitting end of the lamp tube 1 longer than the lower length of the light-emitting end of the lamp tube 1. Thus, the upper part of the light-emitting end of the lamp tube 1 forms a light-blocking structure. When the floodlight is installed at a low position, it blocks the light source from directly entering the field of vision, avoiding strong light stimulation that may cause discomfort or safety hazards. No external baffle is required. At the same time, the inclined light-transmitting glass can reduce dust accumulation on the horizontal surface, and rainwater can naturally wash away the dust, preventing dust accumulation and ensuring good light output efficiency. The angle adjustment is steplessly smooth by loosening the adjusting bolt, and there is no springback after the adjusting bolt is tightened, making the overall structure stable.

[0023] For example, the bottom of the connecting frame 31 is provided with a first rotating part 312, and the first end face gear 311 is provided on one side of the first rotating part 312. The upper part of the mounting base 32 is provided with a second rotating part 322, and the second end face gear 321 is provided on one side of the second rotating part 322. The other side of the first rotating part 312 is provided with a first angle scale value 313. The mounting base 32 is provided with a first angle indicator mark 323 for indicating the first angle scale value 313. By cooperating with the first angle indicator mark 323 and the first angle scale value 313, the angle of the lamp tube 1 can be precisely adjusted, avoiding errors caused by visual observation.

[0024] Furthermore, a second angle scale value 324 is provided on the other side of the second rotating part 322, and a second angle indicator mark 314 is provided on the connecting frame 31 to indicate the second angle scale value 324. When adjusting the angle of the lamp tube 1, the rotation angle of the lamp tube 1 can be accurately read on both sides of the floodlight, which improves the ease of operation of adjusting the angle of the lamp tube 1 and improves the accuracy of the angle adjustment.

[0025] For example, the bottom of the first rotating part 312 is semi-circular, and the mounting base 32 is provided with an arc-shaped surface 325 that rotatably engages with the bottom of the first rotating part 312; the top of the second rotating part 322 is semi-circular, and the connecting frame 31 is provided with an arc-shaped surface 315 that rotatably engages with the top of the second rotating part 322. The semi-circular structure at the bottom of the first rotating part 312 of the connecting frame 31 and the arc-shaped surface 325 on the mounting base 32 form a stable rotating pair, ensuring smooth and wobbly rotation, bearing the weight of the lamp tube 1, and improving the structural stability of the floodlight.

[0026] For example, the mounting base 32 also includes two semi-circular clamps 326, which are fixed by bolts. The second rotating part 322 is disposed on one of the semi-circular clamps 326, so that the floodlight can be quickly and stably installed on the rod-shaped support.

[0027] Specifically, the inner cavity of the lamp tube 1 is provided with a heat sink 12, which is located at the bottom of the light source assembly 2. The heat sink 12 quickly removes the heat generated by the light source assembly 2 through heat conduction, thereby extending the service life of the floodlight.

[0028] Furthermore, the diameter of the lamp tube 1 gradually decreases from the bottom to the top of the lamp tube 1. The lamp tube 1 adopts a bottom-to-top tapering design to enhance the light converging effect and improve the illumination efficiency.

[0029] Specifically, the light source assembly 2 includes a lamp bead plate 21, a lens 22, and a lens barrel 23. The lens 22 is arranged one-to-one with the lamp beads on the lamp bead plate 21. The top surface of the lens 22 is provided with a plurality of anti-glare grooves 221 at intervals. The lens barrel 23 is provided with a light-transmitting cylinder 231 that is one-to-one with the lens 22. The light-transmitting cylinder 231 is cylindrical. The anti-glare grooves 221 allow the light emitted by the lamp beads to be refracted by the lens 22 and then refracted by the uneven anti-glare grooves 221 on the surface of the lens 22, so that the light spot is uniform and glare is reduced. The glare is further reduced by the action of the light-transmitting cylinder 231.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
