Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED light source with a heat dissipation backplate on the back. Background Technology

[0002] LED lights are solid-state light sources that directly convert electrical energy into visible light by releasing energy through the recombination of electrons and holes in semiconductor materials. Compared with traditional light sources such as incandescent lamps and fluorescent lamps, they have significant advantages such as low energy consumption, long lifespan, and fast response, and are the core component of modern lighting and display technologies.

[0003] To maintain a relatively low temperature during long-term operation of LED lights, a metal heat sink is installed on the back of the LED light panel. The heat conduction effect of the metal fins is used to assist in heat dissipation of the LED light. However, LED lights are generally installed on the ceiling, and the metal heat sink connected to the LED light is usually located at the top of the ceiling in a relatively sealed environment. During peak electricity consumption periods, when the temperature is already high, the temperature in the sealed space at the top of the ceiling is also relatively high. This will reduce the auxiliary heat dissipation capacity of the metal heat sink, making it difficult for the LED light to work normally. Utility Model Content

[0004] This invention addresses the problem that during peak electricity usage periods, when temperatures are already high, the enclosed space at the top of the ceiling also experiences relatively high temperatures. This leads to a decrease in the auxiliary heat dissipation capacity of metal heat sinks, hindering the normal operation of LED lights. The invention proposes an LED light source with a heat dissipation backplate on the back.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an LED light source with a heat dissipation backplate on the back, comprising a frame, an LED light board fixedly mounted on the inner wall of the frame by screws, a transparent lampshade snapped onto the inner wall of the frame, a metal heat sink fixedly mounted on one side of the LED light board by screws, and some of the metal heat sinks being provided with auxiliary devices, the auxiliary devices assisting the heat dissipation of the LED light board by setting several pipes that can connect the metal heat sinks to the outside.

[0006] The effect achieved by the above components is as follows: by setting up several pipes, the pipes can connect the metal sheet with the outside world, thereby enabling the originally sealed space to exchange heat with the outside world. At the same time, the pipes can send relatively cool air to one side of the metal sheet heat sink, thereby improving the heat exchange capacity of the metal sheet heat sink, which is conducive to the LED light board working in a relatively low temperature environment.

[0007] Preferably, the auxiliary device includes two extension plates, and baffles are slidably installed on the inner walls of the two extension plates. The baffles are made of metal, and one side of each of the two baffles abuts against one side of the metal radiator. A rectangular frame is provided on one side of the two baffles, and a plurality of pipes are evenly arranged on one side of the rectangular frame.

[0008] The effect achieved by the above components is as follows: push the two baffles so that one end of the two baffles abuts against each other, then install the rectangular frame on one side of the two baffles, and set one end of the pipe connected to the rectangular frame in the space at the bottom of the ceiling, so that the rectangular frame can be connected to the outside through several pipes, thereby making it easier to keep the rectangular frame at a relatively low temperature. The metal rectangular frame can also dissipate heat to the metal heat sink through heat conduction. If necessary, fans can be installed at one end of several pipes to send air to the rectangular frame and the space at the top of the ceiling to assist in the heat dissipation of the LED light panel.

[0009] Preferably, each of the two extension plates has a screw hole block fixedly installed on the side away from each other, and the inner wall of the screw hole block is threaded with a bolt, which is located on one side of the baffle.

[0010] The effect achieved by the above components is as follows: by rotating the bolt, the bolt moves within the inner wall of the bolt hole block until one end of the bolt abuts against one side of the baffle. The bolt can then fix the baffle and the extension plate, thereby preventing the baffle from shifting and causing insufficient contact between the baffle and the metal fin heat sink, which would reduce the heat transfer efficiency between the rectangular frame and the metal fin heat sink.

[0011] Preferably, a rubber block is fixedly installed on the side of the bolt near the baffle.

[0012] The effect achieved by the above components is that by setting up rubber blocks, one end of the bolt can be replaced to abut against one side of the baffle, and the friction between the bolt and the baffle is increased, making the bolt more securely fixed to the baffle.

[0013] Preferably, an auxiliary plate is fixedly installed on the side of each of the two baffles that are far apart, and a spring is fixedly installed on the side of each of the two auxiliary plates that are close to each other, with one end of each of the two springs fixedly installed on one side of the mounting plate.

[0014] The effect achieved by the above components is as follows: by setting springs, when the two baffles are pushed and brought closer to each other, the baffles will compress the springs, causing the springs to deform. When the baffles are removed, both springs will reset and drive one baffle away from each other, thus facilitating the quick installation and removal of the metal plate heat sink.

[0015] Preferably, the spring has a telescopic rod inside, one end of which is fixedly installed on one side of the auxiliary plate, and the other end of which is fixedly installed on one side of the mounting plate.

[0016] The effect achieved by the above components is that by setting up the telescopic rod, the telescopic rod can guide the spring, which helps to prevent the spring from easily bending during deformation.

[0017] Preferably, trapezoidal strips are symmetrically fixedly installed on one side of the rectangular frame, and the two trapezoidal strips are slidably inserted into the inner wall of the baffle.

[0018] The effect achieved by the above components is as follows: by setting two trapezoidal strips, when the two baffles abut against each other, the two trapezoidal strips can be inserted into the inner walls of the two baffles respectively, which can fix the two baffles and the rectangular frame at the same time, and also fix the two baffles to each other, thereby improving the stability of the overall structure.

[0019] Preferably, a connecting plate is snapped onto the inner wall of the rectangular frame, one end of each of the plurality of pipes is fixedly installed on one side of the connecting plate, and the inner walls of each of the plurality of pipes are connected to the inner wall of the rectangular frame.

[0020] The effect achieved by the above components is that by setting up a connecting plate, several pipes and rectangular frames can be connected, and several pipes can be disassembled, thereby facilitating pipe maintenance and replacement.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up several pipes, the pipes can connect the metal sheet with the outside world, thereby enabling the originally sealed space to exchange heat with the outside world. At the same time, the pipes can send relatively cool air to one side of the metal sheet heat sink, thereby improving the heat exchange capacity of the metal sheet heat sink and making it easier for the LED light board to work in a relatively low temperature environment.

[0030] Example 1, referring to Figures 1-3 As shown, this embodiment discloses an LED light source with a heat dissipation backplate on the back, including a frame 1. An LED light board 2 is fixedly installed on the inner wall of the frame 1 by screws. A transparent lampshade 3 is snapped onto the inner wall of the frame 1. A metal heat sink 4 is fixedly installed on one side of the LED light board 2 by screws. (The models of the LED light board 2 and the metal heat sink 4 can be Fusion Optix FOM 01-0045 and Wakefield Thermal Flow LED-3850, respectively.) Some parts of the metal heat sink are provided with auxiliary devices 5. The auxiliary devices 5 assist the heat dissipation of the LED light board 2 by setting several pipes 512 that can connect the metal heat sink 4 with the outside. By setting several pipes 512, the pipes 512 can connect the metal sheet with the outside, thereby enabling the originally sealed space to exchange heat with the outside. At the same time, the pipes 512 can send relatively cool air to one side of the metal heat sink 4, thereby improving the heat exchange capacity of the metal heat sink 4, which is beneficial for the LED light board 2 to work in a relatively low temperature environment.

[0031] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the auxiliary device 5 includes two extension plates 51. A baffle 52, made of metal, is slidably mounted on the inner wall of each extension plate 51. One side of each baffle 52 abuts against one side of the metal radiator 4. A rectangular frame 53 is provided on one side of each baffle 52. Several pipes 512 are evenly arranged on one side of the rectangular frame 53. Pushing the two baffles 52 causes one end of each baffle 52 to abut against each other. The rectangular frame 53 is then installed on one side of the two baffles 52, with one end of the pipes 512 connected to the rectangular frame 53 positioned in the space at the bottom of the ceiling. This allows the rectangular frame 53 to connect to the outside environment through the pipes 512, thus maintaining a relatively low temperature. The metal rectangular frame 53 can also dissipate heat from the metal radiator 4 through heat conduction. Heat dissipation is achieved through the heat sink 4. If necessary, fans can be installed at one end of several pipes 512 to supply air to the rectangular frame 53 and the space at the top of the ceiling to assist in the heat dissipation of the LED light panel 2. Screw holes 54 are fixedly installed on the opposite sides of the two extension plates 51. Bolts 55 are threaded onto the inner wall of the screw holes 54. The bolts 55 are located on one side of the baffle 52. By rotating the bolts 55, the bolts 55 can move on the inner wall of the screw holes 54 until one end of the bolts 55 abuts against one side of the baffle 52. The bolts 55 can then fix the baffle 52 and the extension plates 51, thereby preventing the baffle 52 from shifting and causing insufficient contact between the baffle 52 and the metal heat sink 4, which would reduce the heat conduction efficiency between the rectangular frame 53 and the metal heat sink 4.

[0032] Reference Figure 2 and Figure 3 As shown, a rubber block 56 is fixedly installed on the side of the bolt 55 near the baffle 52. By setting the rubber block 56, one end of the bolt 55 can be replaced to abut against one side of the baffle 52, and the friction between the bolt 55 and the baffle 52 can be increased, making the bolt 55 more firmly fixed to the baffle 52.

[0033] Reference Figure 3As shown, auxiliary plates 57 are fixedly installed on the opposite sides of the two baffles 52, and springs 58 are fixedly installed on the adjacent sides of the two auxiliary plates 57. One end of each spring 58 is fixedly installed on one side of the mounting plate. By setting the springs 58, when the two baffles 52 are pushed and brought closer together, the baffles 52 will compress the springs 58, causing the springs 58 to deform. When the baffles 52 are removed, both springs 58 will reset and drive one baffle 52 away from each other, thus facilitating the quick installation and removal of the metal plate heat sink 4. A telescopic rod 59 is provided inside the spring 58. One end of the telescopic rod 59 is fixedly installed on one side of the auxiliary plate 57, and the other end of the telescopic rod 59 is fixedly installed on one side of the mounting plate. By setting the telescopic rod 59, the telescopic rod 59 can guide the spring 58, which helps to prevent the spring 58 from easily bending during deformation.

[0034] Reference Figure 5 As shown, trapezoidal strips 510 are symmetrically fixedly installed on one side of the rectangular frame 53. The two trapezoidal strips 510 are slidably inserted into the inner wall of the baffle 52. By setting the two trapezoidal strips 510, when the two baffles 52 abut against each other, the two trapezoidal strips 510 can be inserted into the inner wall of the two baffles 52 respectively. This can fix the two baffles 52 and the rectangular frame 53 at the same time, and also fix the two baffles 52 to each other, which can improve the stability of the overall structure. A connecting plate 511 is snapped into the inner wall of the rectangular frame 53. One end of several pipes 512 is fixedly installed on one side of the connecting plate 511. The inner wall of several pipes 512 is connected to the inner wall of the rectangular frame 53. By setting the connecting plate 511, the connecting plate 511 can connect several pipes 512 to the rectangular frame 53, and at the same time facilitate the disassembly of several pipes 512, thereby facilitating the maintenance and replacement of pipes 512.

[0035] Working principle: Pushing the two baffles 52 causes one end of each baffle 52 to abut against each other. The baffles 52 drive the auxiliary plate 57 to compress the spring 58, causing the spring 58 to deform. Install the rectangular frame 53 on one side of the two baffles 52, so that the two trapezoidal bars 510 are respectively inserted into the inner wall of the two baffles 52. Rotate the bolt 55, so that the bolt 55 moves in the inner wall of the screw hole block 54 until the rubber block 56 at one end of the bolt 55 abuts against one side of the baffle 52. Then the bolt 55 can fix the baffle 52 and the extension plate 51, making the contact between the baffle 52 and the metal plate heat sink 4 tighter. Then connect the connecting plate 511 to the inner wall of the rectangular frame 53, and connect the pipe 51. One end of 2 is set in the space at the bottom of the ceiling, so that the rectangular frame 53 can be connected to the outside through several pipes 512, thereby making it easier to keep the rectangular frame 53 at a relatively low temperature. The metal rectangular frame 53 can also dissipate heat to the metal heat sink 4 through heat conduction. If necessary, a fan can be installed at one end of several pipes 512 to blow air into the rectangular frame 53 and the space at the top of the ceiling to assist in the heat dissipation of the LED light board 2. Rotate the two bolts 55 in the opposite direction to release the bolts 55 from fixing the baffle 52. Then both springs 58 will reset and drive one baffle 52 away from each other, thereby facilitating the quick installation and removal of the metal heat sink 4.
