Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a high-efficiency heat dissipation intelligent LED downlight. Background Technology

[0002] LED downlights are lighting fixtures embedded in the ceiling that emit downward light. They use LED light sources and are characterized by being mercury-free, non-toxic, free of electromagnetic pollution and harmful radiation, energy-saving, environmentally friendly, and having a long lifespan. However, LEDs generate a lot of heat when working. If this heat cannot be dissipated effectively in a timely manner, it will seriously affect the performance and lifespan of the LEDs. Most existing LED downlights dissipate heat by opening heat dissipation holes on the lamp body. This heat dissipation method relies on natural air convection, which has low heat dissipation efficiency, and the heat dissipation holes are prone to accumulating dust, affecting the heat dissipation effect. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a high-efficiency heat dissipation intelligent LED downlight.

[0004] Technical Solution: A high-efficiency heat dissipation intelligent LED downlight includes a lamp body with a heat dissipation cover spaced apart on the top of the lamp body. The interior of the lamp body and the interior of the heat dissipation cover are connected by a connecting pipe. A semiconductor cooler is installed inside the connecting pipe. The cooling end and the heat dissipation end of the semiconductor cooler face the interior of the lamp body and the interior of the heat dissipation cover, respectively. Multiple heat dissipation holes are circumferentially spaced apart on the top and bottom of the heat dissipation cover. A filter screen is fixed to each heat dissipation hole. A baffle is slidably connected to the heat dissipation hole. The baffle is used to open or close the heat dissipation hole when the lamp body is working or stopped.

[0005] Optionally, a gear ring is rotatably connected to each of the upper and lower sides of the heat sink. All the baffles on the upper side are fixedly connected to the gear ring on the upper side, and all the baffles on the lower side are fixedly connected to the gear ring on the lower side. A rotating rod is rotatably connected inside the heat sink. Both ends of the rotating rod are fixedly connected to transmission gears, and the two transmission gears mesh with the two gear rings respectively.

[0006] Optionally, a mounting bracket is fixedly connected to the center of the heat sink, and a motor is mounted on the mounting bracket. The output shaft of the motor is connected to the rotating rod via a gear set.

[0007] Optionally, the baffle has raised strips that contact the filter screen and are used to clean the filter screen.

[0008] Optionally, a fan and a second motor are also installed in the middle of the mounting bracket, with the output shaft of the second motor connected to the fan drive.

[0009] Optionally, multiple connecting posts are circumferentially fixed between the bottom of the heat sink and the top of the lamp body, and the connecting posts are used to improve the overall structural strength.

[0010] Beneficial effects: This utility model achieves efficient heat dissipation for LED downlights by integrating semiconductor cooling and active air cooling, thereby improving the performance and lifespan of LEDs. At the same time, the design of opening and closing the heat dissipation holes through the baffle gives the LED downlights good dustproof function and reduces maintenance costs.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0017] Please see Figures 1-4A high-efficiency heat dissipation intelligent LED downlight includes a lamp body 1 and a heat sink 2. The lamp body 1 houses LED light sources and circuit components, while the heat sink 2 is located above the lamp body 1 and connected to it via a connecting pipe 8. Three connecting posts 9 are circumferentially fixed between the bottom of the heat sink 2 and the top of the lamp body 1 to improve the overall structural strength. A semiconductor cooler 3 is installed inside the connecting pipe 8. The semiconductor cooler 3 is a device that uses the thermoelectric effect of semiconductor materials for cooling or heating. In this invention, the cooling end of the semiconductor cooler 3 faces inward towards the lamp body 1 to absorb the heat from the LED light source, etc. The heat generated by the component; the heat dissipation end faces the inside of the heat dissipation cover 2, and is used to transfer the absorbed heat to the air inside the heat dissipation cover 2; the top and bottom of the heat dissipation cover 2 are provided with multiple heat dissipation holes 201 spaced apart in a circumferential manner. These heat dissipation holes 201 are used to exhaust the hot air inside the heat dissipation cover 2, thereby achieving the heat dissipation effect; in order to prevent dust and debris from entering the heat dissipation holes 201, a filter screen 10 is fixedly connected to each heat dissipation hole 201. At the same time, a baffle 4 is slidably connected to the heat dissipation hole 201. These baffles 4 can automatically open or close the heat dissipation holes 201 when the lamp body 1 is working or stopped, thereby achieving dust prevention control of the heat dissipation holes 201.

[0018] To achieve the automatic opening and closing function of the baffles 4, this invention has a gear ring 501 rotatably connected to each of the upper and lower sides of the heat sink 2. All the baffles 4 on the upper side are fixedly connected to the upper gear ring 501, and all the baffles 4 on the lower side are fixedly connected to the lower gear ring 501. A rotating rod 502 is also rotatably connected inside the heat sink 2. Both ends of the rotating rod 502 are fixedly connected to transmission gears 503. These two transmission gears 503 mesh with the two gear rings 501 respectively. When the rotating rod 502 rotates, it drives the two gear rings 501 to rotate synchronously through the transmission gears 503, thereby driving all the baffles 4 to open or close synchronously.

[0019] In order to realize the automatic rotation function of the rotating rod 502, the present invention installs a motor 701 and a gear set 702 on the mounting bracket 6 inside the heat sink 2. The output shaft of the motor 701 is connected to the rotating rod 502 through the gear set 702. When the motor 701 works, it will drive the rotating rod 502 to rotate, thereby realizing the automatic opening and closing of the baffle 4.

[0020] In addition, to further improve the heat dissipation effect, the present invention also provides a protrusion 401 on the baffle 4 that contacts the filter screen 10. When the baffle 4 slides during opening or closing, the protrusion 401 will clean the filter screen 10, thereby removing dust and debris from the filter screen 10 and ensuring that the heat dissipation hole 201 is unobstructed.

[0021] Finally, to further enhance the heat dissipation effect, this utility model also installs a fan 703 and a second motor 704 in the middle of the mounting bracket 6 inside the heat dissipation cover 2. The output shaft of the second motor 704 is connected to the fan 703. When the second motor 704 is working, it will drive the fan 703 to rotate, thereby generating airflow, accelerating the airflow inside the heat dissipation cover 2, and improving the heat dissipation efficiency.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
