Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of COB light source modularization, and in particular relates to a COB light source modular structure. Background Art
[0002] COB light source is a high-efficiency integrated surface light source technology that directly attaches LED chips to a highly reflective mirror metal substrate. This technology eliminates the concept of a bracket and has no electroplating, reflow, or patch processes. Instead, it uses chip-on-board (COB) technology to mount semiconductor chips on a printed circuit board. The electrical connection between the chip and the substrate is achieved by wire stitching and covered with resin to ensure reliability.
[0003] When multiple COB light sources are used in combination, they are often installed on a main substrate. In the existing technology, COB light source modules are replaced by soldering. The COB light source modules are soldered to the substrate to achieve electrical connection between the COB module and the substrate. This method requires the main substrate to be powered off during operation, which is not only inefficient but also inconvenient for the next replacement. For this reason, we propose a modular structure of COB light sources. Utility Model Content

[0006] Preferably, a slider is provided at the bottom of the supporting plate, and the slider is fixedly connected to the supporting plate via a connecting rod.
[0007] Furthermore, the slider is fixedly connected to symmetrically arranged sliding grooves, the two ends of the arc block are respectively slidably connected to the two sliding grooves, and a spring is fixedly connected between the two arc blocks.
[0008] Furthermore, a tenon is fixedly connected to the bottom of the slider. Rotating shafts are rotatably connected to both sides of the tenon. A torsion spring is arranged inside the rotating shafts. A blocking block is fixedly connected to the rotating shafts. Both the upper and lower parts of the blocking block are hook-shaped.
[0009] Furthermore, the slider is slidably connected inside the loading groove. The hook-shaped part at the lower part of the blocking block is in contact with the bottom of the loading groove.
[0010] Furthermore, a positioning rod is also fixedly connected to the bottom of the slider. A limiting piece is fixedly connected to one end of the positioning rod. A driving plate is slidably connected to the positioning rod.
[0011] Preferably, an unlocking piece is fixedly connected to the bolt.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.
[0023] Embodiment: Refer to Figures 1 - 6 , a modular structure of a COB light source, including a light-emitting component 4 installed on a chip 3, further including: a substrate 1 provided with a loading groove 11, a groove corresponding to the follow-up block 232 is opened in the loading groove 11, and a first electrode 111 is arranged in the groove; the chip 3 is installed on the support plate 2 and is electrically connected to the support plate 2, and a contact 27 is arranged at the bottom of the support plate 2; a bolt 5, the bolt 5 passes through the slider 21 and is threadedly connected to the slider 21, and an extrusion section 52 is fixedly connected to the top of the bolt 5; a follow-up block 232 provided with a second electrode 233, the follow-up block 232 is slidably connected to the arc-shaped block 231, and the arc-shaped block 231 is in contact with the extrusion section 52; when the bolt 5 is rotated, the extrusion section 52 moves downward, so that the arc-shaped block 231 drives the follow-up block 232 to slide in a direction away from the extrusion section 52, and the follow-up block 232 is inserted into the groove of the loading groove 11, so that the first electrode 111, the contact 27, and the second electrode 233 are electrically connected;
[0024] A slider 21 is arranged at the bottom of the support plate 2, and the slider 21 is fixedly connected to the support plate 2 through a connecting rod 22; symmetrically arranged sliding grooves 23 are also fixedly connected to the slider 21, both ends of the arc-shaped block 231 are respectively slidably connected to the two sliding grooves 23, and a spring 234 is fixedly connected between the two arc-shaped blocks 231; a tenon 24 is fixedly connected to the bottom of the slider 21, both sides of the tenon 24 are rotatably connected to a rotating shaft 25, a torsion spring is arranged in the rotating shaft 25, a blocking block 251 is fixedly connected to the rotating shaft 25, and both the upper and lower parts of the blocking block 251 are hook-shaped; the slider 21 is slidably connected in the loading groove, and the hook-shaped part at the lower part of the blocking block 251 is in contact with the bottom of the loading groove 11;
[0025] The bottom of the slider 21 is also fixedly connected with a positioning rod 261. One end of the positioning rod 261 is fixedly connected with a limiting piece 262. A driving plate 26 is slidably connected to the positioning rod 261; an unlocking piece 51 is fixedly connected to the bolt 5;
[0026] During installation, the slider 21 is slid into the loading groove 11. During the downward movement of the slider 21, the hook at the bottom of the blocking block 251 abuts against the loading groove 11, causing the blocking block 251 to rotate by a small angle around the rotating shaft 25, so that the blocking block 251 can smoothly slide into the loading groove 11. When the hook at the bottom of the blocking block 251 disengages from the loading groove 11, the torsion spring in the rotating shaft 25 drives the blocking block 251 to reset under the action of the spring force, so that the hook at the bottom of the blocking block 251 hooks the edge of the loading groove 11, thereby completing the fixation of the slider 21;
[0027] After the slider 21 is fixed, since the bolt 5 is threadedly connected to the slider 21, turning the bolt 5 with a screwdriver can make the bolt 5 move downward. The extrusion section 52 at the top of the bolt 5 also moves downward together, extruding the arc-shaped block 231, so that the arc-shaped block 231 slides and expands to both sides along the chute 23. The arc-shaped block 231 will also push the follower block 232, so that the follower block 232 is inserted into the groove opened in the loading groove 11. At this time, the first electrode 111, the contact 27, and the second electrode 233 are electrically connected to supply power to the support plate 2, and the support plate 2 transfers electrical energy to the chip 3, causing the light-emitting member 4 to emit light;
[0028] When it is necessary to repair or replace the chip 3 or the light-emitting member 4, turn the bolt 5 in the reverse direction with a screwdriver. The extrusion section 52 moves upward and no longer presses on the arc-shaped block 231. The arc-shaped blocks 231 approach each other under the action of the spring force of the spring 234, and the follower block 232 is pulled out from the groove opened in the loading groove 11, disconnecting the power supply to the support plate 2. At the same time, due to the upward movement of the bolt 5, the unlocking piece 51 fixedly connected to the bolt 5 also moves upward until it contacts the hook at the top of the blocking block 251. As the bolt 5 continues to move upward, it drives the blocking block 251 to rotate around the rotating shaft 25 again, so that the hook at the bottom of the blocking block 251 disengages from the edge of the loading groove 11. At this time, the slider 21 can be slid out of the loading groove 11 to perform maintenance operations on the chip 3 or the light-emitting member 4.
[0029] The utility model designs a movable second electrode 233. After the slider 21 is installed in the loading groove 11 opened on the substrate 1, turning the bolt 5 can make the second electrode 233, the first electrode 111, and the contact 27 contact each other to supply power to the chip 3. There is no need to use processes such as soldering to connect the circuit after installation, allowing operation in the electrified state of the substrate belt 1. At the same time, the installation process is simplified, which is convenient for disassembly next time. When maintenance is required, turning the bolt 5 can also conveniently cut off the power supply to the support plate 2 and unlock the slider 21, facilitating the removal of the slider 21 from the loading groove 11.
[0030] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model.
