Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spotlight, especially to a low pressure spotlight with customizable dimming. BACKGROUND

[0002] Low voltage spotlight refers to the spotlight that operates at a relatively low voltage, usually 12 volts or 24 volts. These spotlights usually use a transformer to reduce the standard voltage (such as 220 volts or 110 volts) to a safe low voltage level. Low voltage spotlights are widely used in exhibition halls, commercial spaces, and catering places, etc.

[0003] After searching, the patent with the authorization announcement number CN218237181U discloses a low-voltage rotary swing dimming spotlight, relating to the technical field of lamps. It includes a box body, a power cover is installed on the lower surface of the box body near the left side, a power supply compartment is fixedly installed on the lower surface of the power cover, a dimmer is installed in the power supply compartment, a bottom cover is fixedly installed on the lower surface of the power supply compartment, a rotary knob cap is installed on the lower surface of the dimmer, a connecting rod is installed on the second locking nut through the mounting hole, a lamp body is provided on the universal joint, and a second gasket, a spring, a heat sink seat, a PC lamp panel, a lower lens seat, a lens body, a compression ring, and an upper lens seat are installed on the inner wall of the lamp body from top to bottom. The spotlight can rotate and swing the lamp body, and can also lift it for irradiation, allowing for full-range irradiation without dead angles in the showcase, and the size of the focal point can be adjusted. The rotary knob cap is used to adjust the brightness of the light, and the brightness can be adjusted according to the display needs, which is highly practical.

[0004] However, the existing low voltage spotlight still has the following optimization points, for example, when installing and fixing, it is usually fixed and installed on a suspended high pole through multiple fastening bolts and installation pieces. Due to the different sizes and shapes of high poles, the reserved mounting holes are also not in the same position, making it difficult to install different low voltage spotlights on different high poles, which reduces the convenience of using the low voltage spotlight. SUMMARY

[0005] This utility model discloses a customizable dimming low-voltage spotlight. It features a quick-installation and fixing mechanism, allowing the mounting bracket to be lifted via the top plate until it is completely separated from the limiting groove and insertion groove. This allows for the removal of the bracket and clamping plate, enabling the mounting frame to be fitted onto the suspended pole through an opening on one side. The bracket and clamping plate are then reset, and the tightening knob is rotated. Multiple guide rods move the clamping plate until it engages with the inner side of the mounting frame, clamping and fixing the pole. This allows for quick and convenient installation and fixing of the low-voltage spotlight. Because the mounting frame and clamping plate can effectively clamp and fix poles of different shapes and sizes without being affected by pre-drilled mounting holes on the pole, the low-voltage spotlight can be easily installed and fixed onto various poles, greatly improving the ease of installation and use. In summary, this solves the problems in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model discloses a customizable dimming low-pressure spotlight, including a lamp tube, a connecting seat fixedly connected to the top of the lamp tube, a universal ball embedded in the top of the connecting seat, a connecting column fixedly connected to the top of the universal ball, a light source provided at the bottom of the lamp tube, and a first sleeve provided outside the light source of the lamp tube.

[0008] The quick-installation and fixing mechanism includes a frame, a mounting base, a fastening knob, and a clamping plate. The frame is shaped like an inverted U-shape. A through slot is provided at the top of the frame, and insertion slots are provided on the inner walls of both the front and rear sides of the through slot. A limiting slot is provided on the bottom surface of the frame. The bottom of the mounting base passes through the insertion slot and matches and engages with the limiting slot. The top of the mounting base is flush with the top of the frame. One end of the fastening knob passes through the mounting base via a screw. One side of the clamping plate is rotatably connected to one end of the fastening knob via a rotating connector. The size of the clamping plate is smaller than the size of the through slot. Multiple guide rods are fixedly connected to one side of the clamping plate, and the guide rods movably pass through the mounting base.

[0009] A dimming mechanism is located on the outside and bottom of the lamp tube.

[0010] Furthermore, a top plate is fixedly connected to the top of the card holder, a first magnet is fixedly attached to the bottom of the top plate, and a second magnet is fixedly attached to the top of the set frame, with the first magnet and the second magnet being attracted to each other.

[0011] Furthermore, anti-slip pads are attached and fixed to opposite sides of the inside of the clamping plate and the frame, and the anti-slip pads are made of rubber material.

[0012] Furthermore, the dimensions of the card holder match the dimensions of the insertion slot and the limiting slot, and the card holder is fixedly connected to the top plate by welding.

[0013] Furthermore, the dimming mechanism includes a fixed block, an electric actuator, an annular plate, a second sleeve, and a convex lens. There are two fixed blocks and two electric actuators. The two fixed blocks are respectively fixedly installed on the outer sides of the lamp tube. The electric actuator is fixedly installed through the fixed block. The top of the annular plate is fixedly connected to the telescopic ends of the two electric actuators. The second sleeve is fixedly connected to the inner ring of the annular plate. The second sleeve is located outside the first sleeve. The convex lens is fixedly installed inside the second sleeve near the bottom.

[0014] Furthermore, the inner diameter of the second sleeve matches the outer diameter of the first sleeve, and the outer side of the first sleeve is a smooth surface.

[0015] Furthermore, a plane lens is fixedly installed inside the first sleeve, and the plane lens is located below the light source.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. This technical solution features a quick-installation and fixing mechanism, which allows low-voltage spotlights to be clamped and fixed to high poles during installation. The bracket and clamping plate can effectively clamp and fix high poles of different shapes and sizes without being affected by the pre-drilled mounting holes on the poles. This makes it easy to install and fix low-voltage spotlights on different high poles, greatly improving the convenience of installation and use.

[0018] 2. This technical solution incorporates a dimming mechanism, allowing the illumination range or focused light intensity of the low-voltage spotlight to be adjusted according to actual needs during operation.

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "surface", "side", "gap", "peripheral", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Specific Implementation Example 1:

[0029] Reference Figures 1-3A customizable dimming low-voltage spotlight includes a lamp barrel 1, a connecting seat 2 fixedly connected to the top of the lamp barrel 1, a universal ball 3 embedded in the top of the connecting seat 2, a connecting post 4 fixedly connected to the top of the universal ball 3, a light source 5 at the bottom of the lamp barrel 1, and a first sleeve 6 outside the light source 5; a quick-installation fixing mechanism 7, which includes a mounting frame 701, a card holder 702, a fastening knob 703, and a clamping plate 704. The mounting frame 701 is in the shape of an inverted U-shape, and a through groove 705 is opened at the top of the mounting frame 701. Insertion grooves 70 are opened on the inner walls of both the front and rear sides of the through groove 705. 6. A limiting groove 707 is provided on the inner bottom surface of the mounting bracket 701. The bottom of the card holder 702 passes through the insertion groove 706 and matches and engages with the limiting groove 707. The top of the card holder 702 is flush with the top of the mounting bracket 701. One end of the fastening knob 703 passes through the card holder 702 by a screw connection. One side of the clamping plate 704 is rotatably connected to one end of the fastening knob 703 by a rotating connector. The size of the clamping plate 704 is smaller than the size of the through groove 705. Multiple guide rods 708 are fixedly connected to one side of the clamping plate 704. The guide rods 708 movably pass through the card holder 702. The dimming mechanism 8 is located on the outside and bottom of the lamp tube 1.

[0030] The top of the card holder 702 is fixedly connected to the top plate 709, and the bottom of the top plate 709 is fixedly attached to the bottom of the top plate 709. The top of the set frame 701 is fixedly attached to the top of the set frame 701, and the first magnet 710 and the second magnet 711 are attracted to each other. The clamping plate 704 and the set frame 701 are both fixedly attached to opposite sides of the inside of the set frame 701. The anti-slip pads 712 are made of rubber material. The size of the card holder 702 matches the size of the insertion groove 706 and the limiting groove 707, and the card holder 702 and the top plate 709 are fixedly connected by welding.

[0031] In the specific implementation process, when installing the low-voltage spotlight, the bracket 702 can be lifted up through the top plate 709 until the bracket 702 is completely separated from the limiting groove 707 and the insertion groove 706. Then, with the help of the through groove 705, the bracket 702 and the clamping plate 704 can be removed. At this time, the mounting frame 701 can be fitted onto the suspended high pole through the opening on one side. Then, the bracket 702 and the clamping plate 704 are reset, and the fastening knob 703 is turned. With the help of multiple guide rods 708, the clamping plate 704 can be moved until the clamping plate 704 engages with the inner side of the mounting frame 701 to clamp and fix the high pole. This allows for quick and convenient installation and fixing of the low-voltage spotlight. Since the mounting frame 701 and the clamping plate 704 can clamp and fix high poles of different shapes and sizes well, they are not affected by the pre-drilled mounting holes at different positions on the high pole. Therefore, the low-voltage spotlight can be easily installed and fixed on different high poles.

[0032] Among them, the universal ball 3 and the connecting column 4 can be connected with the connecting seat 2 to adjust the angle of the lamp tube 1;

[0033] The top plate 709 can be connected by the adsorption between the first magnet 710 and the second magnet 711, thereby improving the stability of the top plate 709 and thus improving the installation stability of the card holder 702, making the card holder 702 less likely to be easily separated from the set frame 701.

[0034] Among them, the anti-slip pad 712 can increase the friction between the clamping plate 704 and the high pole after the high pole is clamped and fixed, thereby improving the clamping and fixing effect and stability;

[0035] The card holder 702 and the top plate 709 are fixedly connected by welding, which ensures that the card holder 702 and the top plate 709 have good connection strength. Specific Implementation Example 2:

[0037] Reference Figure 4 and Figure 5 In a preferred embodiment, the dimming mechanism 8 includes a fixing block 801, an electric push rod 802, an annular plate 803, a second sleeve 804, and a convex lens 805. There are two fixing blocks 801 and two electric push rods 802. The two fixing blocks 801 are fixedly installed on the outer sides of the lamp tube 1, and the electric push rods 802 are fixedly installed through the fixing blocks 801. The top of the annular plate 803 is fixedly connected to the telescopic ends of the two electric push rods 802. The second sleeve 804 is fixedly connected to the inner ring of the annular plate 803. The second sleeve 804 is located outside the first sleeve 6. The convex lens 805 is fixedly installed inside the second sleeve 804 near the bottom.

[0038] The inner diameter of the second sleeve 804 matches the outer diameter of the first sleeve 6, and the outer side of the first sleeve 6 is a smooth surface; a plane lens 806 is fixedly installed inside the first sleeve 6, and the plane lens 806 is located below the light source 5.

[0039] In the specific implementation process, if it is necessary to change the illumination range or focusing intensity of the low-voltage spotlight during its operation, the two electric actuators 802 can be activated to extend and retract, thereby moving the annular plate 803 and the second sleeve 804 up and down, which in turn moves the convex lens 805 up and down. Thus, the illumination range or focusing intensity produced by the light source 5 can be changed. The principle is that when light passes through the convex lens 805, the curved surface of the convex lens 805 causes the light to refract, thereby changing the direction of light propagation and achieving the purpose of adjusting the illumination range or focusing intensity, so that it can be used in different actual situations.

[0040] The inner diameter of the second sleeve 804 matches the outer diameter of the first sleeve 6. In order to minimize the gap between the first sleeve 6 and the first sleeve 6, dust and impurities are effectively prevented from entering between the second sleeve 804 and the first sleeve 6. The outer side of the first sleeve 6 is a smooth surface to reduce the friction between the second sleeve 804 and the first sleeve 6, so as to facilitate the sliding movement of the second sleeve 804 outside the first sleeve 6.

[0041] The planar lens 806 is designed to effectively prevent dust and impurities from entering the light source 5 and causing damage to it.

[0042] Working principle: When installing a low-voltage spotlight, the mounting bracket 702 can be lifted up through the top plate 709 until the mounting bracket 702 is completely separated from the limiting groove 707 and the insertion groove 706. Then, with the help of the through groove 705, the mounting bracket 702 and the clamping plate 704 can be removed. At this time, the mounting frame 701 can be fitted onto the suspended high pole through the opening on one side. Then, the mounting bracket 702 and the clamping plate 704 are reset, and the fastening knob 703 is turned. With the help of multiple guide rods 708, the clamping plate 704 can be moved until the clamping plate 704 engages with the inner side of the mounting frame 701 to clamp and fix the high pole. This allows for quick and convenient installation and fixing of the low-voltage spotlight. Since the mounting frame 701 and the clamping plate 704 can clamp and fix high poles of different shapes and sizes well, they are not affected by the pre-drilled mounting holes at different positions on the high pole. Therefore, it is easy to install and fix the low-voltage spotlight on different high poles.

[0043] During the operation of low-voltage spotlights, if it is necessary to change the illumination range or focused light intensity, the two electric actuators 802 can be activated to extend and retract, causing the annular plate 803 and the second sleeve 804 to move up and down, thereby causing the convex lens 805 to move up and down. Thus, the illumination range or focused light intensity produced by the light source 5 can be changed. The principle is that when light passes through the convex lens 805, the curved surface of the convex lens 805 causes the light to refract, thereby changing the direction of light propagation and achieving the purpose of adjusting the illumination range or focused light intensity, so that it can be used in different actual situations.

[0044] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
