Description

Technical Field

[0001] This utility model relates to the field of LED light source board technology, specifically to an LED light source board with a snap-fit ​​fixing structure. Background Technology

[0002] LED light source boards play a vital role in modern lighting, and their high energy efficiency, long lifespan, and environmental friendliness make them widely used in various luminaires. However, traditionally, LED light source boards are installed into the luminaire housing in two ways: first, by using screws, and second, by directly applying adhesive. Both methods require tools to perform the installation steps, making the process relatively cumbersome and increasing construction time and costs.

[0003] In view of this, we propose an LED light source board with a snap-fit ​​fixing structure to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an LED light source board with a snap-fit ​​fixing structure, which has the advantages of convenient and quick connection of the LED light source board to the lamp housing, improving installation efficiency, and solving the above-mentioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an LED light source board with a snap-fit ​​fixing structure, comprising a light source board body and a lamp housing, wherein a hinge plate is fixedly connected to the lower surface of the light source board body, and a first pin and a second pin are fixedly connected to the inner side of the hinge plate, and a first arc-shaped clamping block and a second arc-shaped clamping block are rotatably connected to the outer surface of the first pin, and a connecting plate is fixedly connected to the outer surface of both the first and second arc-shaped clamping blocks, wherein an ear block is fixedly connected to the upper surface of the connecting plate, a third pin is fixedly connected to the outer surface of the ear block, and an arc-shaped spring is rotatably connected to the outer surface of the third pin, wherein a rectangular block is fixedly connected to the inside of the lamp housing, and a cylindrical protrusion is fixedly connected to one end of the rectangular block.

[0008] Preferably, the first arc-shaped clamping block and the second arc-shaped clamping block are symmetrically arranged around their contacting surfaces, and the end of the arc-shaped spring piece away from the third pin is rotatably connected to the second pin.

[0009] With the above technical solution, by picking up the light source board body, aligning the openings of the first and second arc-shaped clamping blocks with the cylindrical protrusion, and then gently pressing down on the light source board body, the first and second arc-shaped clamping blocks are locked onto the outer surface of the cylindrical protrusion. Due to the contact force between the arc-shaped spring pieces and the second and third pins on the connecting plate, the contact force applied by the arc-shaped spring pieces will keep the first and second arc-shaped clamping blocks closed through the transmission of the connecting plate, thus preventing loosening and achieving quick installation of the light source board body inside the lamp housing.

[0010] Preferably, two pins are fixedly connected to the inner side of the hinge plate, and a Z-shaped lever is fixedly connected to the outer surface of the connecting plate.

[0011] Using the above technical solution, by flicking the Z-shaped lever upwards with a finger, one of the connecting plates moves upwards. This causes the connecting plate to rotate either the first or second arc-shaped clamping block around the pin shaft, thus separating the first and second arc-shaped clamping blocks. During this process, the arc-shaped spring is in a retracted state, allowing the first and second arc-shaped clamping blocks to be removed from the cylindrical protrusion, achieving the purpose of quickly disassembling the light source board body from inside the lamp housing.

[0012] Preferably, there are two rectangular blocks and two cylindrical protrusions, and a limiting piece is provided at the end of the pin shaft away from the ear block.

[0013] With the above technical solution, when the connecting plate rotates around the pin shaft by moving the Z-shaped paddle, the arc-shaped spring is curled by the force. By setting a limiting piece at one end of the pin shaft, the arc-shaped spring can be prevented from detaching from the pin shaft.

[0014] Preferably, a plurality of equally spaced LED beads and facets are mounted on the upper surface of the light source board body.

[0015] Through the above technical solution, the LED lamp beads emit light after being connected to the power supply. The set prismatic body has multiple rhomboid faces, and the outer surface is polished to a mirror finish, which can reflect, refract, and diffract the light emitted by the LED lamp beads. The lamp housing is prismatic in shape, which has a light-focusing effect. The overall structure can improve the luminous effect of LED lamp beads.

[0016] Preferably, a heat sink is installed on the lower surface of the light source board body, and thermal grease is applied between the heat sink and the light source board body.

[0017] With the above technical solution, when the LED beads are working, they will generate a certain amount of heat, which will be conducted to the light source board body. The light source board body will then transfer the heat to the heat sink. By applying thermal grease between the heat sink and the light source board body, the heat transfer effect can be increased, and the heat sink can help to quickly dissipate heat, thus achieving the purpose of heat dissipation.

[0018] Compared with the prior art, this utility model provides an LED light source board with a snap-fit ​​fixing structure, which has the following advantages:

[0019] 1. This utility model aligns the light source plate body with the cylindrical protrusion inside the lamp housing and gently presses it down. The first and second arc-shaped clamping blocks will then lock onto the cylindrical protrusion. The arc-shaped spring sheet is used to maintain the closed state, thus achieving quick installation. During disassembly, by moving the Z-shaped lever, the connecting plate and the arc-shaped clamping blocks are rotated, causing them to separate from the cylindrical protrusion, thus achieving quick disassembly. This design greatly simplifies the installation and maintenance process and improves the convenience of operation.

[0020] 2. This utility model installs multiple LED beads and faceted bodies on the light source board body. The multi-rhomboid facets and mirror polishing of the faceted bodies can effectively reflect, refract, and diffract the light emitted by the LED beads, enhancing the light utilization efficiency. At the same time, the frustum-shaped design of the lamp housing has a light-focusing effect, which improves the overall luminous effect of the LED beads. In addition, the heat sink installed on the lower surface of the light source board body is coated with thermal grease between itself and the light source board, which can effectively conduct and dissipate the heat generated by the LED during operation, ensuring the stable operation of the LED light source board and extending its service life.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 An LED light source board with a snap-fit ​​fixing structure includes a light source board body 1 and a lamp housing 11. A hinge plate 2 is fixedly connected to the lower surface of the light source board body 1. Pin 1 3 and pin 2 4 are fixedly connected to the inner side of the hinge plate 2. A first arc-shaped clamping block 5 and a second arc-shaped clamping block 6 are rotatably connected to the outer surface of pin 1 3. A connecting plate 7 is fixedly connected to the outer surface of both the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6. An ear block 8 is fixedly connected to the upper surface of the connecting plate 7. Pin 3 9 is fixedly connected to the outer surface of the ear block 8. An arc-shaped spring piece 10 is rotatably connected to the outer surface of pin 3 9. A rectangular block 12 is fixedly connected to the inside of the lamp housing 11. A cylindrical protrusion 13 is fixedly connected to one end of the rectangular block 12.

[0029] Specifically, the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6 are symmetrically arranged around their contact surfaces, and the end of the arc-shaped spring piece 10 away from the pin 3 9 is rotatably connected to the second pin 4. The advantage is that by picking up the light source plate body 1, aligning the openings of the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6 with the cylindrical protrusion 13, and then gently pressing down on the light source plate body 1, the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6 are locked onto the outer surface of the cylindrical protrusion 13. Because the arc-shaped spring piece 10, in conjunction with the second pin 4 and the third pin 9, exerts a resisting force on the connecting plate 7, the resisting force applied by the arc-shaped spring piece 10, transmitted through the connecting plate 7, keeps the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6 closed, thus preventing loosening and achieving rapid installation of the light source plate body 1 inside the lamp housing 11.

[0030] Specifically, two pins 4 are fixedly connected to the inner side of the hinge plate 2, and a Z-shaped lever 14 is fixedly connected to the outer surface of the connecting plate 7. The advantage is that by flicking the Z-shaped lever 14 upwards with a finger, one of the connecting plates 7 moves upwards. This causes the connecting plate 7 to rotate either the first arc-shaped clamping block 5 or the second arc-shaped clamping block 6 around the pin 3, thus separating the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6. During this process, the arc-shaped spring 10 is in a retracted state, which allows the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6 to be removed from the cylindrical protrusion 13, achieving the purpose of quickly disassembling the light source board body 1 from inside the lamp housing 11.

[0031] Specifically, there are two rectangular blocks 12 and two cylindrical protrusions 13, and a limiting piece is provided at the end of the pin 3 9 away from the ear block 8. The advantage is that when the Z-shaped lever 14 is turned to drive the connecting plate 7 to rotate around the pin 3, the arc-shaped spring 10 is subjected to force and curls up. By providing a limiting piece at one end of the pin 3 9, the arc-shaped spring 10 can be prevented from detaching from the pin 3 9.

[0032] Specifically, multiple equally spaced LED beads 15 and faceted bodies 16 are mounted on the upper surface of the light source board body 1. The advantages are that the LED beads 15 emit light after being powered on, and the faceted bodies 16, with their multiple rhomboid faces and polished outer surfaces, reflect, refract, and diffract the light emitted by the LED beads. The lamp housing 11 is frustum-shaped, providing a focusing effect, and the overall structure enhances the luminous effect of the LED beads 15.

[0033] Specifically, a heat sink 17 is installed on the lower surface of the light source board body 1, and thermal grease is applied between the heat sink 17 and the light source board body 1. The advantage is that when the LED beads 15 are working, they generate heat, which is conducted to the light source board body 1. The light source board body 1 then transfers this heat to the heat sink 17. Applying thermal grease between the heat sink 17 and the light source board body 1 increases the heat transfer effect, and the heat sink 17 facilitates rapid heat dissipation, thus achieving the purpose of heat dissipation.

[0034] In use, by picking up the light source board body 1, aligning the openings of the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6 with the cylindrical protrusion 13, and then gently pressing down on the light source board body 1, the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6 are locked onto the outer surface of the cylindrical protrusion 13, achieving the purpose of quickly installing the light source board body 1 inside the lamp housing 11; when it is necessary to remove the light source board body 1 from the lamp housing 11, by pushing the Z-shaped lever 14 upwards, it causes the first arc-shaped clamping block 5 or the second arc-shaped clamping block 6 to rotate around the pin 3, thus separating the first arc-shaped clamping block 5 and the second arc-shaped clamping block 6, achieving the purpose of quickly removing the light source board body 1 from the lamp housing 11.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
