Abstract
Description
Technical Field
[0001] This invention relates to the field of optical measurement equipment, and more specifically to an adjustable cup support structure. Background Technology
[0002] As a key component in an optical system, the reflector, through its precise parabolic surface design and rotationally symmetrical structure, can efficiently reflect divergent light emitted by a light source into a parallel beam, significantly reducing light loss and achieving precise directional transmission of light energy. The reflector typically consists of two parts: a parabolic reflector for reflection and an LED chip as the light source. In practical applications, the relative position of the reflector and the LED chip directly determines the focusing effect and spot quality of the main light source.
[0003] The reflector support structure is used to install and support the reflector. Generally, the reflector and the LED are fixed to the mounting plate with screws, and the positions of the lamp cover and the LED are fixed to achieve support for the reflector. However, most existing light cup support structures have a common technical bottleneck: after the light cup is installed and fixed, the front and rear positions of the LED beads in the lamp cover cannot be finely adjusted, resulting in the fixed and unadjustable focusing position of the light source. This defect is particularly prominent in scenarios that require frequent adjustment of the spot size, focusing distance, or precision optical experiments, which seriously limits the application flexibility of the light cup and the adjustment accuracy of the optical system. Summary of the Invention
[0004] This invention addresses the technical problems existing in the prior art by providing a dimmable cup support structure.
[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An adjustable light cup support structure includes: a front mounting plate, a light cup, a front cover plate, a rear cover plate, a power supply line, a rear mounting plate, screws, and nuts. A guide rod is fixedly connected to the lower surface of the front mounting plate, and a base is fixedly connected to one end of the guide rod. The base is used to support the front mounting plate. The light cup is disposed inside the front mounting plate and can move back and forth inside the front mounting plate. The front and rear positions of the light cup are fixed by the front cover plate and screws. The light cup is composed of a parabolic lampshade and an LED located at the center of the lampshade. The LED can move back and forth in the lampshade. The power supply line is slidably connected to the rear mounting plate, and one end of the power supply line is fixedly connected to the LED.
[0006] In a preferred embodiment, the LED bead is installed at the center of the reflector and can move back and forth with the power supply line. A lead screw is rotatably connected to one side of the front mounting plate via a bearing seat. The lead screw is threadedly connected to the rear mounting plate, and a knob is fixedly provided at one end of the lead screw to drive the lead screw to rotate and move the rear mounting plate to adjust the distance between the front mounting plate and the rear mounting plate.
[0007] In a preferred embodiment, an installation gap is provided between the front cover plate and the front mounting plate. After adjusting the front and rear positions of the optical cup, the front cover plate is fixed with screws. Based on the fixing of the front cover plate, the optical cup is pressed. A horizontal guide rail is fixedly connected to one side of the front mounting plate, and the rear mounting plate is slidably sleeved on the surface of the horizontal guide rail. The surface of the rear mounting plate is threaded with bolts that fit against the horizontal guide rail to fix the position of the rear mounting plate.
[0008] In a preferred embodiment, a movable plate is slidably connected inside the rear mounting plate, and two connecting rods fixedly connected to the lampshade are fixedly connected to one side of the movable plate. The power supply line is slidably inserted into the interior of the movable plate, and a movable frame is fixedly connected to one side of the movable plate. A threaded rod is threadedly connected to the surface of the movable frame, and one end of the threaded rod is rotatably connected to the rear mounting plate.
[0009] In a preferred embodiment, a threaded screw is rotatably connected to one side of the rear mounting plate via a bearing seat. An adjustment frame is threadedly connected to the surface of the threaded screw, and a locking mechanism is provided on the surface of the adjustment frame. The adjustment frame is sleeved on the surface of the power supply line.
[0010] In a preferred embodiment, the locking mechanism includes a fixed frame fixedly connected to the surface of the adjusting frame. Electromagnets connected to the power supply line are fixedly connected to both sides inside the fixed frame. An arc-shaped plate coaxially arranged with the electromagnet is slidably connected inside the fixed frame. The arc-shaped plate fits against the fixed frame and can form a limiting groove with the same diameter as the threaded screw.
[0011] In a preferred embodiment, a stud is fixedly connected to the upper surface of the adjustment frame, and one end of the stud passes through the adjustment frame and is in contact with the power supply line. Based on the horizontal movement of the stud, the connection relationship between the power supply line and the adjustment frame is controlled. The front and rear positions of the power supply line on the rear mounting plate are fixed by the adjustment frame and the stud.
[0012] In a preferred embodiment, after adjusting the position of the lampshade and the LED beads of the light cup, the entire structure is placed vertically, and glue is poured from the power supply line side to fix the relative position of the lampshade and the LED beads, thus completing the final installation of the light cup.
[0013] The beneficial effects of this invention are as follows: Through the synergy of the front mounting plate, the light cup, the front cover plate, the rear cover plate, the power supply line, and the rear mounting plate, the power supply line is slidably connected to the rear mounting plate. Pulling the power supply line drives the LED to move inside the lamp cover, adjusting the position of the LED. After fixing the position of the LED with a stud, the rear mounting plate is moved by a screw, adjusting the position of the light cup inside the front mounting plate. After adjusting the position of the light cup, the front cover plate is fixed to the front mounting plate based on the bolts, the front cover plate, and the screws, thus pressing the light cup. This combines the adjustment of the mounting plate spacing with the independent fine-tuning of the light cup assembly, avoiding the inability to fine-tune the front and rear positions of the LED in the lamp cover, which would result in a fixed and unadjustable light source focusing position. This improves the application flexibility of the light cup and the adjustment accuracy of the optical system. Through the coordinated operation of structures such as the moving plate, threaded rod, adjusting bracket, threaded screw, and locking mechanism, after adjusting the position of the LED, the tightening of the bolts makes the bolts press against the power supply line, completing the tight connection between the power supply line and the adjusting bracket. Rotating the bolt screw causes the adjusting bracket to move the power supply line slightly, allowing for more precise control of the LED position. Furthermore, through the cooperation of the moving plate and the threaded rod, the moving plate can move the lamp cover inside the front mounting plate, slightly adjusting the position of the lamp cover, making the lamp cover position adjustment more precise, thereby further improving the accuracy of the reflector position adjustment. Based on the coordination of multiple components in the locking mechanism, when the LED is powered, electrical energy is transferred to the electromagnet, causing the electromagnet to generate magnetic force, which attracts the arc plate, making the arc plate fit against the fixing frame and forming a limiting groove with the same diameter as the threaded rod. This limits the threaded rod and prevents it from rotating on its own during use, which would cause the power supply line to move and affect the adjustment accuracy of the LED.

Detailed Implementation
[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0017] Reference Figures 1-7 An adjustable light cup support structure includes: a front mounting plate 1, a light cup 2, a front cover plate 3, a rear cover plate 4, a power supply line 5, a rear mounting plate 6, screws, and nuts. A guide rod is fixedly connected to the lower surface of the front mounting plate 1, and a base 7 is fixedly connected to one end of the guide rod. The base 7 is used to support the front mounting plate 1. The light cup 2 is disposed inside the front mounting plate 1 and can move back and forth inside the front mounting plate 1. The front and rear positions of the light cup 2 are fixed by the front cover plate 3 and screws. The light cup 2 is composed of a parabolic lampshade and an LED located at the center of the lampshade. The LED can move back and forth in the lampshade. The power supply line 5 is slidably connected to the rear mounting plate 6, and one end of the power supply line 5 is fixedly connected to the LED. A 0.5-1mm installation gap is reserved between the front cover plate 3 and the front mounting plate 1. After adjusting the front and rear positions of the light cup 2, the front cover plate 3 is slightly deformed by tightening the screws, thereby pressing the light cup 2 more tightly and significantly improving the installation stability and vibration resistance. The power supply line 5 uses high-temperature resistant, low-loss polytetrafluoroethylene insulated wire, and has a certain tensile strength. In the embodiment of the above technical solution, the lamp cover and lamp beads of the light cup 2 are set inside the front mounting plate 1. By pulling the power supply line 5, the position of the lamp beads inside the lamp cover is adjusted. After the position of the lamp beads is adjusted, the position of the lamp beads and the power supply line 5 is fixed by the cooperation of multiple components. Then, the gap between the rear mounting plate 6 and the front mounting plate 1 is adjusted, so that the rear mounting plate 6 drives the light cup 2 to move inside the front mounting plate 1, adjusting the position of the light cup 2. After the position of the light cup 2 is adjusted, the front cover plate 3 is fixed to the front mounting plate 1 by screws to press the light cup 2, thus completing the installation of the light cup 2. This realizes the combination of mounting plate spacing adjustment and independent fine adjustment of the light cup 2 components, avoiding the inability to fine adjust the front and rear positions of the lamp beads in the lamp cover, which would result in the fixed and unadjustable focusing position of the light source. This improves the application flexibility of the light cup 2 and the adjustment accuracy of the optical system. Reference Figure 1 and Figure 2 The LED bead is installed in the center of the light cup 2 and can move back and forth with the power supply line 5. A lead screw 8 is rotatably connected to one side of the front mounting plate 1 through a bearing seat. The lead screw 8 is threadedly connected to the rear mounting plate 6, and a knob is fixedly provided at one end of the lead screw 8 to drive the lead screw 8 to rotate and move the rear mounting plate 6 to adjust the distance between the front mounting plate 1 and the rear mounting plate 6. When adjusting the position of the rear mounting plate 6, rotate the lead screw 8 so that its thread drives the rear mounting plate 6 to move to one side of the front mounting plate 1, changing the gap between the rear mounting plate 6 and the front mounting plate 1, thereby achieving a coarse adjustment of the position of the light cup 2. An installation gap is provided between the front cover plate 3 and the front mounting plate 1. After adjusting the front and rear positions of the light cup 2, the front cover plate 3 is fixed with screws. Based on the fixing of the front cover plate 3, the light cup 2 is pressed. A horizontal guide rail 9 is fixedly connected to one side of the front mounting plate 1, and the rear mounting plate 6 is slidably sleeved on the surface of the horizontal guide rail 9. The surface of the rear mounting plate 6 is threaded with bolts that fit with the horizontal guide rail 9 to fix the position of the rear mounting plate 6. The horizontal guide rail 9 is a high-precision guide rail. The guide rail is made of stainless steel and the surface is hardened. The roughness Ra≤0.8μm. The rear mounting plate 6 can move back and forth on the guide rail. After the relative position of the front mounting plate 1 and the rear mounting plate 6 is determined, the bolts are tightened to press the rear mounting plate 6 against the surface of the horizontal guide rail 9 to fix it, so that the position of the rear mounting plate 6 is more stable after adjustment. Reference Figure 5 and Figure 6 The rear mounting plate 6 has a sliding connection to a movable plate 10. Two connecting rods that are fixedly connected to the lamp cover are fixedly connected to one side of the movable plate 10. The power supply line 5 is slidably inserted into the interior of the movable plate 10. A movable frame 11 is fixedly connected to one side of the movable plate 10. A threaded rod 12 is threadedly connected to the surface of the movable frame 11, and one end of the threaded rod 12 is rotatably connected to the rear mounting plate 6. After adjusting the position of the optical cup 2 by moving the rear mounting plate 6, the threaded rod 12 is rotated to drive the moving frame 11 to move on one side of the rear mounting plate 6, thereby moving the moving plate 10. The moving plate 10 then drives the connecting rod to move the optical cup 2 inside the front mounting plate 1, slightly adjusting the position of the optical cup 2 inside the front mounting plate 1. The threaded design makes the position adjustment of the optical cup 2 more precise, further improving the accuracy of the optical cup 2 position adjustment. A threaded screw 13 is rotatably connected to one side of the rear mounting plate 6 via a bearing seat. An adjusting bracket 14 is threadedly connected to the surface of the threaded screw 13. A locking mechanism is provided on the surface of the adjusting bracket 14. The adjusting bracket 14 is sleeved on the surface of the power supply line 5. The threaded screw 13 is used to drive the adjustment frame 14 to move; The adjusting bracket 14 is used to drive the power supply line 5 to move when the pin 18 presses against the power supply line 5; A pin 18 is fixedly connected to the upper surface of the adjusting frame 14, and one end of the pin 18 passes through the adjusting frame 14 and is in contact with the power supply line 5. Based on the horizontal movement of the pin 18, the connection relationship between the power supply line 5 and the adjusting frame 14 is controlled. The front and rear positions of the power supply line 5 on the rear mounting plate 6 are fixed by the adjusting frame 14 and the pin 18. The bolt 18 is used to control the connection between the power supply line 5 and the adjusting frame 14; After adjusting the position of the LED beads by pulling the power supply wire 5, the pin 18 is rotated so that one end of it fits tightly against the power supply wire 5, thus fixing the power supply wire 5 and achieving the fixed installation of the power supply wire 5 and the adjustment bracket 14. Then, by rotating the threaded screw 13, it drives the adjustment bracket 14 to move on one side of the rear mounting plate 6, thereby driving the power supply line 5 to move synchronously, adjusting the position of the power supply line 5 and the lamp bead by a small margin, and controlling the position of the lamp bead more precisely. Thus, by precisely controlling the position of the lamp cover and the lamp bead, the accuracy of the position adjustment of the light cup 2 is further improved, and the fine adjustment of the position of the light cup 2 is achieved. Reference Figure 7 The locking mechanism includes a fixed frame 15 fixedly connected to the surface of the adjusting frame 14. Electromagnets 16 connected to the power supply line 5 are fixedly connected to both sides inside the fixed frame 15. An arc plate 17 coaxially arranged with the electromagnets 16 is slidably connected inside the fixed frame 15. The arc plate 17 fits against the fixed frame 15 and can form a limiting groove with the same diameter as the threaded screw 13. A metal shielding cover is added between the electromagnet 16, the lamp bead and the lamp bead power supply line 5. The galvanized steel plate is ≥0.5mm thick and the shielding cover is grounded to form an electromagnetic shielding barrier to block the radiation interference generated by the electromagnet 16 from directly acting on the lamp bead. When the LED bead position is adjusted and powered on, electrical energy is transferred to the electromagnet 16, causing the electromagnet 16 to generate magnetic force, attracting the arc plate 17, causing the arc plate 17 to move and fit against the fixing frame 15, forming a limiting groove with the same diameter as the threaded rod 13, limiting the threaded rod 13, and preventing the threaded rod 13 from rotating on its own and causing the power supply line 5 to move, which would affect the adjustment accuracy of the LED bead. After adjusting the position of the lampshade and the LED of the light cup 2, place the entire structure vertically and apply glue from the side of the power supply line 5 to fix the relative position of the lampshade and the LED of the light cup 2, thus completing the final installation of the light cup 2. After the adhesive is poured in, it flows naturally along the power supply line 5 to the connection between the LED chip and the lamp cover, forming a firm and fixed structure. This potting process not only maintains the relative position of the LED chip and the lamp cover stable over a long period of time, but also effectively isolates the LED chip from the air, preventing performance degradation due to oxidation.
