Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED module technology, specifically to an LED module with dustproof function. Background Technology
[0002] LED modules are the most widely used LED products. They vary greatly in structure and electronics. A simple LED module consists of a circuit board containing LEDs and a housing. More complex modules include controls, constant current sources, and related heat dissipation treatments to improve LED lifespan and luminous intensity.
[0003] According to a public notice of an LED module protection device (Announcement No.: CN221258789U), the aforementioned application incorporates heat dissipation holes to promote air circulation between the inside and outside of the lamp holder. This allows the natural airflow to remove heat from the lamp holder. Simultaneously, when the temperature is too high, a fan is activated to accelerate air circulation and improve heat dissipation capacity. Dustproof meshes are installed in the heat dissipation holes using a snap-fit method, making it easy to install and remove the dustproof meshes and facilitate subsequent cleaning and unblocking, thus enhancing the practicality of the device's heat dissipation capacity.
[0004] However, in practical applications, the device revealed certain problems during the dust filter replacement process. Specifically, when the dust filter becomes clogged due to prolonged use and needs cleaning or replacement, operators must remove it, leaving the heat dissipation holes directly exposed to the external environment. During this process, dust, particles, and other impurities in the outside air are likely to enter the lamp cover through the heat dissipation holes. These impurities may not only adhere to the LED module and surrounding components, affecting heat dissipation, but may also damage the electrical and optical performance of the LED module, shortening its lifespan and even causing malfunctions. Furthermore, the lack of dust protection measures during dust filter replacement may leave the LED module unprotected during the process, increasing the risk of dust, moisture, and other contaminants entering due to improper operation or unexpected situations, further reducing the reliability and safety of the device.

[0007] A fixed frame is slidably connected to the inner wall of the lamp holder. A second filter plate is fixed to the inner wall of the fixed frame. Two sets of the second filter plates are provided, and the two sets of the second filter plates are symmetrically arranged with the center line of the fixed frame as the axis of symmetry.
[0008] Preferably, the alternating assembly further includes a fixing plate, one end of which is fixed to the inner wall of the lamp holder, and the end of the fixing plate away from the lamp holder passes through the fixing frame, and the fixing plate is slidably connected to the fixing frame. A spring is fixed to the surface of the fixing frame, and the end of the spring away from the fixing frame is fixed to the inner wall of the lamp holder.

When the pull rod is pulled, the fixing frame and the connecting plate move synchronously, and the second filter plate is parallel to the first filter plate, taking over the dust filtering work of the first filter plate. When the pull rod moves, the pull rod moves into the through hole, and at the same time, the baffle moves with the pull rod. The baffle can block the through hole to prevent external dust from entering the lamp holder through the through hole. When the first filter plate is replaced, dust will not enter the lamp holder.
[0009] Preferably, the limiting component includes a connecting plate, which is fixed to the inner wall of the fixed frame. A fixing block is fixed to the surface of the connecting plate, a sliding block is slidably connected to the surface of the connecting plate, and a magnet is fixed to the surface of the connecting plate.

A second spring is fixed to the surface of the locking block, and the end of the second spring away from the locking block is fixed to the inner wall of the groove. The sliding block is magnetically connected to the magnet. When the connecting plate moves, the fixing block moves synchronously. The side of the fixing block near the sliding block abuts against the side of the locking block away from the inclined surface. The locking block limits the fixing block, the connecting plate, and the fixed frame, thereby stabilizing the filter plate. Pulling the lever again, when the locking block abuts against the side of the sliding block away from the fixing block, the lever is released, the first spring retracts and resets, the fixed frame and the connecting plate reset, and the locking block drives the sliding block to move closer to the fixing block. When the sliding block and the surface of the fixing block are in contact, the locking block moves along the surface of the sliding block and the fixing block, thereby releasing the limiting.
[0010] Preferably, a transparent lampshade is snapped onto the surface of the lamp holder, so as not to interfere with normal lighting operation.
[0011] Preferably, the side of the fixed block away from the sliding block is set as an inclined surface, and the side of the sliding block away from the fixed block is set as an inclined surface. When the side of the fixed block away from the inclined surface comes into contact, it can limit the movement of the fixed block and the locking block. When the sliding block is driven by the locking block to fit against the fixed block, the limiting can be released.
[0012] Preferably, the end surface of the locking block away from the second spring is set as an inclined surface, which allows the locking block to enter the sliding groove when it comes into contact with the surfaces of the fixed block and the sliding block.

When the pull rod moves, the pull rod moves in the through hole, and at the same time the baffle moves with the pull rod. The baffle can block the through hole to prevent external dust from entering the lamp holder through the through hole. When replacing the first filter plate, dust will not enter the lamp holder. The second filter plate can temporarily take over the filtering and dustproof work.
[0015] 2. This dustproof LED module, through the setting of limiting components, can stabilize the fixed frame and filter plate by limiting the locking block and fixing block to each other through the locking block, fixing block and spring two when the pull rod is pulled. When the replacement and cleaning are completed, the pull rod is pulled again, and the fixing frame can be released through the sliding block, magnet, fixing block, spring two and spring one, so that the fixing frame and filter plate two can be reset.

[0022] The fixed frame 50 is slidably connected to the inner wall of the lamp holder 1. A second filter plate 51 is fixed to the inner wall of the fixed frame 50. Two sets of filter plates 51 are provided, and both sets are symmetrically arranged about the center line of the fixed frame 50. The alternating component 5 also includes a fixed plate 52. One end of the fixed plate 52 is fixed to the inner wall of the lamp holder 1, and the end of the fixed plate 52 away from the lamp holder 1 passes through the fixed frame 50. The fixed plate 52 is slidably connected to the fixed frame 50. A first spring 53 is fixed to the surface of the fixed frame 50. The end of the first spring 53 away from the fixed frame 50 is fixed to the inner wall of the lamp holder 1. A through hole 56 is provided on the surface of the lamp holder 1. A pull rod 54 is fixed to the surface of the fixed frame 50. The end of the pull rod 54 away from the fixed frame 50 passes through the through hole 56. Hole 56, pull rod 54 passes through baffle 55, pull rod 54 is fixedly connected to baffle 55, baffle 55 is slidably connected to the surface of lamp holder 1, alternating component 5 also includes limiting member 57, pull rod 54, can drive fixed frame 50 and connecting plate 570 to move synchronously, spring 1 53 is stretched, at this time filter plate 2 51 is parallel to filter plate 2, take over the dust filtering work of filter plate 2. When pull rod 54 moves, pull rod 54 moves in through hole 56, baffle 55 moves with pull rod 54, baffle 55 can block through hole 56 to prevent external dust from entering lamp holder 1 through through hole 56. When replacing filter plate 2, dust will not enter lamp holder 1, filter plate 2 51 can temporarily take over the filtering and dust prevention work.
[0023] The limiting component 57 includes a connecting plate 570, which is fixed to the inner wall of the fixing frame 50. A fixing block 571 is fixed to the surface of the connecting plate 570, a sliding block 572 is slidably connected to the surface of the connecting plate 570, and a magnet 573 is fixed to the surface of the connecting plate 570. A groove 574 is formed on the surface of the fixing plate 52, and a locking block 575 is slidably connected to the inner wall of the groove 574. A second spring 576 is fixed to the surface of the locking block 575, and the end of the second spring 576 away from the locking block 575 is fixed to the inner wall of the groove 574. The sliding block 572 is magnetically connected to the magnet 573. The side of the fixing block 571 away from the sliding block 572 is set as an inclined surface, and the side of the sliding block 572 away from the fixing block 571 is set as an inclined surface. The surface of the end of the locking block 575 away from the second spring 576 is set with... The inclined plane, when the connecting plate 570 moves, the fixing block 571 moves synchronously. When the side of the fixing block 571 near the sliding block 572 abuts against the side of the locking block 575 away from the inclined plane, the locking block 575 limits the fixing block 571, the connecting plate 570, and the fixing frame 50, thus stabilizing the filter plate 2 51. Pulling the lever 54 again, when the locking block 575 abuts against the side of the sliding block 572 away from the fixing block 571, the lever 54 is released, the spring 1 53 retracts and resets, the fixing frame 50 and the connecting plate 570 reset, and the locking block 575 drives the sliding block 572 to move closer to the fixing block 571. When the sliding block 572 is in contact with the surface of the fixing block 571, the locking block 575 moves along the surface of the sliding block 572 and the fixing block 571, thereby releasing the limit, and the fixing frame 50 resets normally. A transparent lampshade is attached to the surface of the lamp holder 1 for convenient normal lighting use.
[0024] When filter plate 2 needs to be replaced due to excessive dust accumulation on its surface after prolonged use, pulling the lever 54 will cause the fixed frame 50 and connecting plate 570 to move synchronously, stretching spring 53.

At this time, the inclined surface of the locking block 575 on the surface of the fixing block 571 abuts, and the locking block 575 enters the sliding groove 574. The second spring 576 is compressed. When the side of the fixing block 571 near the sliding block 572 abuts against the side of the locking block 575 away from the inclined surface, the second spring 576 is released. This allows the locking block 575 to limit the fixing block 571, the connecting plate 570, and the fixing frame 50, thus stabilizing the filter plate 2 51. At this time, the filter plate 1 2 can be removed normally for further processing. Cleaning and replacement are performed to prevent external dust from entering the lamp holder 1 and affecting the operation of the LED module 4. Alternating filtration by filter plate 2 51 prevents dust from entering. After cleaning, filter plate 2 is reinstalled on the surface of the lamp holder 1. Then, pull rod 54 is pulled again, causing the surface of the locking block 575 to contact the surface of the sliding block 572. When the locking block 575 and the sliding block 572 contact the side away from the fixing block 571, pull rod 54 is released, and spring 1 53 retracts to its original position. At this point, the fixing frame 50 and connecting plate 57... 0 Reset. At this time, the locking block 575 drives the sliding block 572 to move closer to the fixed block 571. When the sliding block 572 is in contact with the surface of the fixed block 571, the locking block 575 moves along the surface of the sliding block 572 and the fixed block 571, thereby releasing the limit. At this time, the fixed frame 50 is reset normally. At this time, the magnet 573 attracts the sliding block 572 to reset. The filter plate 2 is no longer parallel to the filter plate 1. When replacing the filter plate 1, dust will not enter the lamp holder 1. The filter plate 2 can temporarily take over the filtering and dust prevention work.
