[0023] The present invention will be described in further detail below with reference to the accompanying drawings.
[0024] An adjustable spotlight, such as Figure 1 、 2 As shown, it includes a spotlight body, a heat dissipation structure and an adjustment bracket.
[0025] Spotlight body, such as Figure 3 As shown, it includes a lamp housing 9, an LED lamp group 13, a beam adjustment structure and a light source point adjustment structure.
[0026] The lamp housing 9 is a tubular structure with both ends facing forward and backward and with hollowed-out upper sidewalls. A circle of limiting ribs 12 is formed outward on the front end and the sidewalls close to the front end. Three LED lamp groups 13 are arranged circumferentially within the lamp housing 9, and a round rod is formed at the rear end (a square hole is left on the sidewall of the round rod to pass through the round rod). The light source point adjustment structure includes a rear shell 10, a positioning plate 15, and a limiting slide rod 14; the rear shell 10 is a cap structure with an open front end, and is movably sleeved on the rear end of the lamp housing 9. The rear end surface of the rear shell 10 is formed with an arc-shaped handle 4, and a positioning plate 15 is fixed in the front cap mouth. Three limiting slide grooves 16 are arranged circumferentially on the positioning plate 15 (the specific shape is as follows: Figure 4As shown), one end of the three limiting slide bars 14 is fixed on the inner wall of the lamp housing 9 along the circumferential direction, and the other end is gathered and fixed at the center of the lamp housing 9. The square holes of the round rods at the rear end of the LED lamp group 13 are movably sleeved on the limiting slide bars 14, and the ends are movably matched with the corresponding limiting slide grooves 16. After the positioning plate 15 is rotated, the LED lamp group 13 slides along the limiting slide bars 14 (moves inward or outward) under the action of the limiting slide grooves 16, thereby changing the distance between the LED lamp groups 13. The light beam adjustment structure includes a front sleeve 11, a convex lens 7, an adjustment slot 5 and an adjustment handle 6; the convex lens 7 is embedded in the front tube mouth of the front sleeve 11, and a circle of limiting ribs 12 is formed on the inner wall at the rear end of the front sleeve 11, and the limiting ribs 12 are movably sleeved on the tube body between the two circles of limiting ribs 12 of the lamp housing 9. The adjustment slot 5 is a plate structure with a horizontal strip-shaped notch in the middle (the shape is as shown). Figure 2 As shown), the rear end is fixed to one side of the heat dissipation structure, the adjustment handle 6 is correspondingly formed on the side wall of the front sleeve 11, and is movably fitted in the notch of the adjustment slot 5 (the adjustment handle 6 is formed with a disc-shaped structure for holding on the outside of the adjustment slot 5). By moving the adjustment handle 6 back and forth, the distance between the LED lamp group 13 and the convex lens 7 changes, and the focus of the light beam changes.
[0027] The heat dissipation structure includes a heat dissipation plate 8 and a heat dissipation shell 3; the heat dissipation plate 8 is embedded in the hollow part of the side wall of the lamp housing 9, and the material (with excellent thermal conductivity) is the existing technology. The lower part of the heat dissipation shell 3 forms a sleeve (the heat dissipation plate 8 is hollowed out) and is fixed to the outside of the lamp housing 9. A row of dense heat dissipation slots are formed on the top and two side surfaces for heat dissipation.
[0028] The adjustment bracket includes a base 1 and a U-shaped frame 2; the U-shaped frame 2 is arranged with its opening facing upward and its two ends are respectively rotatably connected to the two sides of the heat dissipation shell 3, and the bottom is rotatably connected to the top of the base 1, and there is friction at each rotating connection, so that the adjustable spotlight can be fixed by the adjustment bracket after adjusting the illumination direction, and a non-slip pad is also provided on the bottom surface.
[0029] The LED lamp group 13 is existing technology, and the power cord can be arranged as follows: one end is connected to the LED lamp group 13 through the inside of the rear end rod of the LED lamp group 13, and the other end is collected in the rear shell 10 and then passes through the rear end cap of the rear shell 10 (a hole needs to be punched) to connect to the power supply.
[0030] In the specific implementation of this embodiment:
[0031] Turn on the LED light group 13 to emit a light beam forward, adjust the state of the adjustment bracket to adjust the direction and angle of the light beam so that it falls on the target point, rotate the rear shell 10 of the light source point adjustment structure and slide the front sleeve 11 of the light beam adjustment structure back and forth to adjust the aperture size and brightness at the target point to the required state (the light beam adjustment structure changes the focal length, thereby changing the aperture size, and the light source point adjustment structure changes the distance between the LED light groups 13, so that the overlapping area of the light beams of each LED light group 13 changes, and the brightness and aperture shape are adjusted).
[0032] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
