Description

Technical Field

[0001] This utility model relates to the field of LED lamp technology with high-efficiency heat dissipation, specifically to an LED lamp with high-efficiency heat dissipation. Background Technology

[0002] An LED light is an electroluminescent semiconductor chip that is fixed to a support with silver or white glue. Then, silver or gold wires are used to connect the chip and the circuit board. The chip is sealed with epoxy resin to protect the internal core wires. Finally, a housing is installed. Therefore, LED lights have good shock resistance. An LED is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light.

[0003] In the current technology, the heat dissipation of LED lights mainly relies on passive heat dissipation, which connects the semiconductor chip to the heat sink or heat exchanger, so that the chip can transfer heat to the heat sink or heat exchanger, and then the heat sink or heat exchanger is exposed to the outside world, so that the heat of the chip can be transferred to the outside world. This heat dissipation method is inefficient and requires the replacement of the heat sink, which is inconvenient to operate. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an LED lamp with high-efficiency heat dissipation to solve the technical problem of low heat dissipation efficiency of heat sink.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency heat dissipation LED lamp, comprising an LED lamp, a heat sink plate mounted on the upper end of the LED lamp, a fixed housing fixedly connected to the upper end of the LED lamp, a mounting plate fixedly connected to the upper end of the fixed housing, a dustproof groove fixedly connected to the upper end of the mounting plate, a support rod fixedly connected to the upper end of the mounting plate, a dustproof cover fixedly connected to the upper end of the support rod, wind baffles movably connected around the fixed housing, and the fixed housing and the wind baffles are movably connected via a pivot, and a fan is connected to the upper end of the heat sink plate.

[0006] By adopting the above technical solution, this utility model uses the rotation of the fan to cause the external airflow to push the baffle plate, which opens the baffle plate around the fixed shell and opens the air inlet. This allows the fan to discharge the surrounding air from above the fan through the round hole. When the wind blows to the dust cover above the fan, the air flows in all directions, causing the air to blow the dustproof groove and blow out the dust inside the dustproof groove. This also drives the airflow above the heat sink, achieving the effect of heat dissipation for the heat sink while preventing dust from entering, thus achieving a highly efficient heat dissipation effect.

[0007] Furthermore, the mounting plate has a ventilation opening at its upper end, and the cross-section of the ventilation opening is circular.

[0008] By adopting the above technical solution, it is easy for gas to flow out from inside the device, thus achieving the effect of heat dissipation.

[0009] Furthermore, mounting brackets are fixedly connected to the four corners of the upper end of the mounting plate, and screw holes are provided on the upper end of the mounting brackets.

[0010] By adopting the above technical solution, it is easy to fix the LED light to the outside world with screws.

[0011] Furthermore, a motor is installed inside the fan, and the motor's power interface is connected to the LED light power supply structure.

[0012] By adopting the above technical solution, the fan and LED lights can be turned on or off simultaneously, achieving the effect of heat dissipation only when in use.

[0013] Furthermore, the lower cross-sectional area of ​​the dust cover is smaller than the upper cross-sectional area of ​​the dust groove, and both the dust groove and the dust cover have circular cross-sections.

[0014] By adopting the above technical solution, it is easy for gas to flow out from the gap between the dustproof groove and the dustproof cover, and it is not necessary to prevent external dust from falling into the device.

[0015] Furthermore, the heat sink has a slot inside that mates with the motor shaft, and the slot has a circular cross-section.

[0016] By adopting the above technical solution, it is easy to connect the motor power supply wiring to the LED light.

[0017] Furthermore, magnets are installed inside the bottom end of the wind deflector and inside the fixed shell, with the magnet inside the fixed shell located below the wind deflector.

[0018] By adopting the above technical solution, the wind deflector can prevent dust from all sides of the fixed shell when not in use.

[0019] In summary, the present invention has the following beneficial effects: The present invention uses the rotation of the fan to cause the external airflow to push the baffle plate, which opens the baffle plate around the fixed shell and opens the air inlet. This allows the fan to discharge the surrounding air from above the fan through the round hole. When the wind blows to the dust cover above the fan, the air flows in all directions, causing the air to blow the dustproof groove and blow out the dust inside the dustproof groove. This also drives the airflow above the heat sink, achieving the effect of heat dissipation of the heat sink while preventing dust from entering, thus achieving a highly efficient heat dissipation effect.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] A high-efficiency heat dissipation LED lamp, as shown in Figures 1-6, includes an LED lamp 1, a heat sink 11 mounted on the upper end of the LED lamp 1, and a fixed housing 2 fixedly connected to the upper end of the LED lamp 1 to protect the internal components. A mounting plate 5 is fixedly connected to the upper end of the fixed housing 2, and a dustproof groove 7 is fixedly connected to the upper end of the mounting plate 5. When not in use, dust accumulates in the dustproof groove 7, thus preventing dust from entering the internal components. A support rod 10 is fixedly connected to the upper end of the mounting plate 5, and a dustproof cover 6 is fixedly connected to the upper end of the support rod 10. The dustproof cover 6 is fixedly connected to the mounting plate 5. Wind deflectors 3 are movably connected around the fixed housing 2, and the fixed housing 2 and the wind deflectors 3 are movably connected via a pivot 9, achieving effective dust prevention for the internal components. The device is designed to facilitate the rotation of the baffle plate 3 along the rotating shaft 9 during use. The upper end of the heat sink 11 is connected to a fan 8, which facilitates the airflow inside the device and thus dissipates heat from the heat sink 11. In this invention, the rotation of the fan 8 causes the external airflow to push the baffle plate 3, opening the baffle plates 3 around the fixed shell 2 and opening the air inlet. This allows the fan 8 to expel the surrounding air from above the fan 8 through the round hole. When the wind blows onto the dust cover 6 above the fan 8, the air flows in all directions, causing the air to blow away the dust in the dust groove 7 and drive the airflow above the heat sink 11, achieving the effect of dissipating heat from the heat sink 11 while preventing dust from entering, thus achieving a highly efficient heat dissipation effect.

[0030] Please see Figure 2The upper end of the mounting plate 5 is provided with a ventilation opening, and the cross-section of the ventilation opening is circular. By setting the above structure, this utility model facilitates the flow of gas out of the device and achieves the effect of heat dissipation.

[0031] Please see Figure 1 Mounting brackets 4 are fixedly connected to the four corners of the upper end of the mounting plate 5, and screw holes are opened at the upper end of the mounting brackets 4. By setting the above structure, this utility model makes it easy for the LED light 1 to be fixed to the outside world by screws.

[0032] Please see Figure 3 The fan 8 has a motor installed inside, and the motor power interface is connected to the power structure of the LED light 1. By setting the above structure, this utility model allows the fan 8 and the LED light 1 to be turned on or off at the same time, so as to achieve the effect of heat dissipation only when in use.

[0033] Please see Figure 4 The lower cross-section of the dust cover 6 is smaller than the upper cross-sectional area of ​​the dust groove 7, and the cross-sections of the dust groove 7 and the dust cover 6 are circular. By setting the above structure, this utility model facilitates the flow of gas out from the gap between the dust groove 7 and the dust cover 6, and does not require the use of external dust to prevent it from falling into the device.

[0034] Please see Figure 3 The heat sink 11 has a slot inside that matches the motor shaft, and the slot has a circular cross-section. By setting the above structure, this utility model facilitates the connection of the motor power supply wiring to the LED light 1.

[0035] Please see Figure 3 Magnets are installed inside the bottom of the wind deflector 3 and inside the fixed shell 2, and the magnet inside the fixed shell 2 is below the wind deflector 3. By setting the above structure, this utility model makes it easy for the wind deflector 3 to prevent dust from the surrounding area of ​​the fixed shell 2 when not in use.

[0036] The working principle of this utility model is as follows: When in use, the operator turns on the power, at which time the LED light 1 turns on and the internal fan 8 of the device turns on at the same time. At this time, the fan 8 blows the air inside the device, causing the air to flow out from the top of the fan 8.

[0037] At this time, the air pressure inside the device decreases and the external air pressure pushes the baffle plate 3 around the fixed shell 2. With the continuous rotation of the fan 8, the baffle plate 3 rotates along the rotating shaft 9 into the device. At this time, the baffle plate 3 opens and the fan 8 blows the outside air upward from the air inlet, so that the air inside the device circulates. The fan 8 also blows the air above the heat sink 11 upward and makes the outside air contact the heat sink 11, absorbing heat from the heat sink 11, thereby achieving the effect of heat dissipation of the heat sink 11.

[0038] At this time, air flows out from above the fan 8 through the round hole. Guided by the dustproof plate 6, the air is blown to the top of the dustproof groove 7 and blows out the dust inside the dustproof groove 7, preventing dust from entering the device.

[0039] When LED light 1 is turned off, fan 8 also stops. At this time, baffle 3 loses the thrust of airflow and rotates along shaft 9 under the action of gravity. At the same time, the magnet inside baffle 3 attracts the magnet inside fixed shell 2, causing baffle 3 to reset, thereby closing the inlet and sealing the fixed shell 2 to prevent external dust from entering the device from the air inlet, thus achieving the effect of dust prevention.
