Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figures 1 to 8This utility model provides a technical solution: a heat sink structure, including a tray 1, a heat sink 9, an LED lamp module 2, and an LED power driver. The tray 1 has a groove for mounting the LED lamp module 2 inside, and a reserved hole 3 for wiring of the LED lamp module 2 is opened in the middle of the tray 1. The LED lamp module 2 is connected to the LED power module 5 inside the housing 4 through wires. The housing 4 is fixed to the lower end of the tray 1. Embedding grooves for mounting heat-conducting sheets 6 are opened at intervals at the lower end of the tray 1. The upper end of the heat-conducting sheet 6 contacts the back of the LED power module 5 through a first thermally conductive silicone grease layer 7, and the lower end of the heat-conducting sheet 6 abuts against the heat dissipation end 10 of the heat sink 9 through a second thermally conductive silicone grease layer 8. The heat dissipation end 10 is evenly distributed on the outside of the heat sink 9. An air inlet groove is opened in the middle of the heat sink 9 for the open groove in the middle of the housing 4 to communicate with it.

[0029] The housing 4 has reserved slots on both sides for installing the air-cooled box 11 and the exhaust box 12. Cooling fans 13 and exhaust fans 14 are installed inside the air-cooled box 11 and the exhaust box 12, respectively. Multiple cooling fans 13 and exhaust fans 14 are connected to the controller 15 via wires. The controller 15 is fixed inside the housing 4 via a frame 16. An infrared temperature sensor 17 is installed through the middle of the frame 16 and is connected to the controller 15 via wires. This invention considers the increasing heat generated by the lamp over time. This device can use the infrared temperature sensor 17 to detect the temperature generated by the LED power driver and select active and passive heat dissipation, thereby providing timely and rapid heat dissipation for the LED power driver and the LED lamp module 2. The controller 15's control chip inputs the temperature threshold for the device's operation. Subsequently, after the device generates heat, the infrared temperature sensor 17 detects the heat generated by the LED power driver and LED module 2. The heat is transferred to the interior of the housing 4. When the detected heat does not exceed the temperature threshold, passive heat dissipation is achieved through the heat sink 9, heat conduction plate 6, open slot, and air inlet slot, i.e., heat dissipation is achieved through temperature transfer. When the detected temperature exceeds the temperature threshold, the controller 15 activates the cooling fan 13 and exhaust fan, thereby enabling the exhaust fan 14 and cooling fan 13 to work together to accelerate the circulation of external cold air through the heat sink 9, air inlet slot, and housing 4, thereby removing the heat generated during operation and completing active heat dissipation. When the temperature returns to normal, the cooling fan 13 and exhaust fan 14 stop working.

[0030] The tray 1 has a high-transmittance lampshade 18 installed on its upper end. Multiple fixing feet 19 are integrally formed on the bottom of the high-transmittance lampshade 18. Each fixing foot 19 has a protruding end 20 fixed on its side that abuts against the limiting groove on the side of the tray 1. By setting the fixing feet 19 in conjunction with the protruding end 20, the high-transmittance lampshade 18 and the tray 1 can be quickly installed. When the protruding end 20 of the fixing foot 19 abuts into the limiting groove of the tray 1, the tray 1 and the high-transmittance lampshade 18 will be fixed.

[0031] The bottom of the housing 4 is integrally formed with a plastic part 21. The middle of the plastic part 21 is provided with a thread for the installation of the limiting ring 22. The upper surface of the plastic part 21 is fixed with a heat-resistant anti-slip pad 23. The bottom of the plastic part 21 is equipped with a lamp holder 24, which is connected to the LED power driver circuit. The limiting ring 22 is used to fix the heat sink 9 that is sleeved on the outside of the housing 4. When the heat dissipation end 10 of the heat sink 9 comes into contact with the heat conduction plate 6, the limiting ring 22 and the plastic part 21 are tightened, and the heat-resistant anti-slip pad 23 comes into contact with the lower end of the heat sink 9 to complete the fixation.

[0032] Both the air-cooled box 11 and the exhaust box 12 have slots on their outer sides for air intake or exhaust. A first dustproof net 25 is provided on the outside of the slots. The first dustproof net 25 is fixed to the exhaust box 12 or the air-cooled box 11 by screws. By setting the first dustproof net 25, the interior of the air-cooled box 11 and the exhaust box 12 is protected from dust, preventing dust from entering and adhering to the surface of the LED power driver and affecting the heat dissipation of the LED power driver.

[0033] The open slot is provided with a second dustproof net 26, which is fixed to the housing 4 by screws. The second dustproof net 26 plays a role in preventing dust from entering the open slot and then entering the interior of the housing 4 during the air supply process.

[0034] The housing 4 has symmetrical air guide plates 27 inside, with one end of the air guide plate 27 facing the reserved hole 3. By setting the air guide plate 27, a portion of the cold air delivered by the cooling fan 13 is guided to the reserved hole 3. This portion of cold air will enter the reserved hole 3 and meet the back base of the LED light module 2, carrying away some of the heat, thereby helping the LED light module 2 to dissipate heat.

[0035] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
