Description

An LED light with a heat dissipation device Technical Field

[0001] This application relates to the field of LED lights, and more particularly to an LED light with a heat dissipation device. Background Technology

[0002] LED lights, as a highly efficient and energy-saving lighting device, have been widely used in homes, industries, and commercial sectors in recent years. Their advantages, such as low energy consumption, long lifespan, and environmental friendliness, have greatly promoted technological progress in the lighting industry.

[0003] Chinese Patent CN222798923U discloses a high-efficiency heat dissipation LED lamp, including a housing. An LED light panel is disposed inside the housing. A heat-conducting plate is fixedly installed on the top of the LED light panel, and heat dissipation fins are fixedly installed on the top of the heat-conducting plate. A heat dissipation mechanism is fixedly installed on the housing. The heat dissipation mechanism includes a first ventilation plate, a second ventilation plate, and a guide plate. The heat-conducting plate and heat dissipation fins act as heat sinks to dissipate heat from the LED light panel. The first and second ventilation plates facilitate airflow between the inside and outside of the housing. A cooling fan assembly introduces strong convective air into the housing, increasing the air intake and ensuring sufficient air contact between the heat dissipation fins and the airflow is guided by the guide plate, openings, and unevenly distributed vents, directing most of the airflow to the root of the heat-accumulating heat dissipation fins, thereby improving airflow utilization and heat dissipation efficiency.

[0004] Regarding the aforementioned technologies, after prolonged use, the ventilation plate is prone to accumulating impurities, which may cause blockage and affect the heat dissipation effect. Summary of the Invention

[0005] To reduce filter clogging and improve heat dissipation, this application provides an LED light with a heat dissipation device.

[0006] The LED lamp with a heat dissipation device provided in this application adopts the following technical solution:

[0007] An LED lamp with a heat dissipation device includes a mounting housing and an LED lamp board. The LED lamp board is disposed on the mounting housing. One end of the mounting housing has a connection port. A filter screen is connected to the mounting housing and covers the connection port. The filter screen is detachably connected to the mounting housing via a connector.

[0008] By adopting the above technical solution, the heat generated by the LED light board is discharged through the filter screen during use. When the filter screen is covered with impurities, it can be removed from the mounting housing through the connector, which facilitates the cleaning and replacement of the filter screen, reduces the clogging of the filter screen, and improves the heat dissipation effect.

[0009] Optionally, the filter screen is connected to the mounting housing via a connecting plate. The filter screen is connected to the connecting plate, and the connecting element includes a limiting block. The limiting block is connected to the mounting housing, and the connecting plate has a limiting groove. The limiting block slides along the length of the limiting groove and engages with the connecting plate.

[0010] By adopting the above technical solution, when installing the filter screen, the connecting plate is moved along the length direction of the limiting groove, so that the limiting block slides and fits in the limiting groove along the length direction of the limiting groove, and the filter screen is brought closer to or away from the connection port, thereby facilitating the disassembly and installation of the filter screen.

[0011] Optionally, the connector further includes a first magnetic block and a second magnetic block. The first magnetic block is connected to the limiting block, and the second magnetic block is connected to the inner wall of the limiting groove. When the filter screen covers the connection port, the first magnetic block and the second magnetic block approach each other and attract each other.

[0012] By adopting the above technical solution, when installing the filter screen, the connecting plate is moved so that the limiting block is embedded in the limiting groove, and the limiting block slides along the length of the limiting groove to cooperate with the limiting groove. When the filter screen covers the connection port, the first magnetic block and the second magnetic block attract each other, thereby making the connecting plate stably connected to the mounting shell.

[0013] Optionally, the mounting housing includes a heat dissipation cavity and a mounting cavity. A heat-conducting plate is connected inside the mounting housing. The LED light board is located inside the mounting cavity and connected to the heat-conducting plate. The heat dissipation cavity and the mounting cavity are separated by the heat-conducting plate. The heat dissipation cavity is provided with a plurality of heat dissipation fins, which are spaced apart from each other. The heat dissipation fins are connected to the heat-conducting plate.

[0014] By adopting the above technical solution, when in use, the heat generated by the LED light board is directed to the heat sink through the heat conduction plate and then dissipated through the heat sink fins, thereby accelerating the heat dissipation of the LED light board and improving the heat dissipation effect.

[0015] Optionally, the heat sink fins are rotatably connected to the heat conduction plate, and the mounting housing is provided with a rotating assembly for driving the heat sink fins to rotate.

[0016] By adopting the above technical solution, during use, the rotating component drives the heat dissipation fins to rotate, thereby accelerating the airflow in the heat dissipation cavity, accelerating the heat dissipation of the heat dissipation fins, and improving the heat dissipation efficiency.

[0017] Optionally, the rotating assembly includes a pusher, a connecting rod, a first rod, and a second rod. The connecting rod is slidably fitted to the mounting housing. The pusher is used to push the connecting rod to move. One end of the first rod is hinged to the connecting rod, and the other end of the first rod is hinged to the second rod. The other end of the second rod is connected to the heat dissipation fins.

[0018] By adopting the above technical solution, when the pusher moves the connecting rod, the connecting rod moves the first rod, and the second rod follows the first rod and pushes the heat dissipation fins to rotate, thereby improving the heat dissipation effect.

[0019] Optionally, the mounting housing includes a heat sink and a lampshade, the heat sink and the lampshade being connected to both ends of the heat-conducting plate respectively, the heat sink and the heat-conducting plate forming a heat dissipation cavity, the lampshade and the heat-conducting plate forming a mounting cavity, and the lampshade being detachably connected to the heat-conducting plate.

[0020] By adopting the above technical solution, the lamp cover can be detachably connected to the heat conduction plate, which facilitates the maintenance or replacement of the LED light board.

[0021] Optionally, a mounting ring is connected to one end of the heat-conducting plate near the lamp cover, and a connecting block is connected to the inner wall of the lamp cover. The mounting ring has a connecting groove, the length direction of which is consistent with the circumferential direction of the mounting ring. The connecting block slides and fits into the connecting groove along the length direction of the connecting groove. One end of the connecting groove has a moving opening for the connecting block to pass through and move away from the mounting ring.

[0022] By adopting the above technical solution, when installing the lampshade, the connecting block is inserted into the connecting groove through the movable port, and the lampshade is rotated circumferentially along the mounting ring. This causes the connecting block to slide circumferentially in the connecting groove along the mounting ring, moving the connecting block away from the movable port. This allows the lampshade to be installed on the mounting ring. When removing the lampshade, the lampshade is rotated, causing the connecting block to move closer to the movable port. The connecting block moves away from the connecting groove through the movable port, moving the lampshade away from the mounting ring. This facilitates the installation and removal of the lampshade.

[0023] Optionally, the heat-conducting plate and the heat sink can be detachably connected via mounting hardware.

[0024] By adopting the above technical solution, the heat conduction plate and the mounting cover can be detachably connected, which facilitates the cleaning of the heat dissipation fins at the moving port, reduces impurities on the surface of the heat dissipation fins, and improves the heat dissipation effect.

[0025] Optionally, a fan is connected inside the housing, with the fan outlet facing the heat dissipation fins.

[0026] By adopting the above technical solution, when in use, the heat generated by the LED light board is transferred to the heat dissipation fins through the heat conduction plate, and the fan blows air onto the heat dissipation fins, thereby accelerating the heat dissipation of the heat dissipation fins and improving the heat dissipation effect.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. During use, the heat generated by the LED light board is discharged through the filter screen. When impurities adhere to the filter screen, the filter screen can be removed from the mounting housing through the connector, which facilitates the cleaning and replacement of the filter screen, reduces the clogging of the filter screen, and improves the heat dissipation effect.

[0029] 2. When installing the filter screen, move the connecting plate along the length of the limiting groove so that the limiting block slides and fits into the limiting groove along the length of the limiting groove, and so that the filter screen is closer to or further away from the connection port, thereby facilitating the removal and installation of the filter screen.

[0030] 3. When installing the filter screen, move the connecting plate so that the limiting block is embedded in the limiting groove, and let the limiting block slide along the length of the limiting groove to cooperate with the limiting groove. When the filter screen covers the connection port, the first magnetic block and the second magnetic block attract each other, so that the connecting plate is stably connected to the mounting shell.

[0053] The implementation principle of an LED lamp with a heat dissipation device according to an embodiment of this application is as follows: During use, the heat generated by the LED lamp board 200 is conducted to the heat dissipation fins 300 through the heat conduction plate 140. When the filter screen 400 is adhered to the impurity movement port 172, the connecting plate 600 moves along the length direction of the heat dissipation cover 120, so that the limiting block 710 slides and connects to the limiting groove 621 along the length direction of the heat dissipation cover 120. This makes the limiting block 710 move away from the limiting groove 621 and the connecting plate 600 move away from the heat dissipation cover 120, thereby facilitating the disassembly, replacement or cleaning of the filter screen 400, reducing the situation of impurities clogging the filter screen 400, and improving the heat dissipation effect.
