Description

Technical Field

[0001] The utility model relates to the technical field of dustproofing of LED lamps, in particular to an LED lamp with a dustproof structure. Background Art

[0002] LED is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of the LED is a semiconductor chip. One end of the chip is attached to a bracket, one end is the negative pole, and the other end is connected to the positive pole of the power supply, so that the entire chip is encapsulated by epoxy resin.

[0003] Currently, when using LED light-emitting diodes, they need to be cooled. Most existing cooling methods require fans to blow external air into the lamp to dissipate the generated heat. However, there is a lot of dust and lint in the air. These impurities can easily adhere to the LED light-emitting diodes during air cooling and contaminate them. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an LED lamp with a dustproof structure.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] An LED lamp with a dustproof structure comprises a mounting sleeve, an aluminum alloy heat-conducting sleeve is provided between the inner walls of the mounting sleeve, a lamp holder is provided between the inner walls of the mounting sleeve near one end edge, and an aluminum alloy heat dissipation mesh sleeve is fixed to one side of the lamp holder;

[0007] One side of the aluminum alloy heat-conducting sleeve is closed, the aluminum alloy heat dissipation mesh sleeve extends to the interior of the aluminum alloy heat-conducting sleeve, and the outer surface of the aluminum alloy heat dissipation mesh sleeve is in contact with the inner wall of the aluminum alloy heat-conducting sleeve.

[0008] Optionally, a plurality of aluminum alloy heat sinks are fixed to the outer surface of the aluminum alloy heat conductive sleeve at equal intervals along the circumferential direction and extend through the outside of the mounting sleeve.

[0009] Optionally, the side wall of the aluminum alloy heat-conducting sleeve is provided with a through hole extending to one side of the closed end, and the inner wall of the through hole is provided with multiple air outlets at equal intervals, and one end of each of the multiple air outlets extends to one side of the aluminum alloy heat sink.

[0010] Optionally, a plurality of support rods are fixed equidistantly along the circumferential direction between the inner walls of the mounting sleeve near one side edge, a motor is fixed between one ends of the plurality of support rods, and a plurality of fan blades are fixed equidistantly along the circumferential direction at the output end of the motor.

[0011] Optionally, a rear end cover is provided between the inner walls of the mounting sleeve near one side edge, a plurality of air inlets are provided on one side of the rear end cover at equal intervals along the circumferential direction, and a filter is provided between the inner walls of the rear end cover.

[0012] Optionally, a fixing frame is provided between the outer surfaces of both sides of the mounting sleeve near one edge, and a plurality of LED lamp bodies are equidistantly provided on the other side of the lamp holder.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0014] 1. First, extend the aluminum alloy heat dissipation mesh sleeve to the inside of the aluminum alloy thermal conductive sleeve, and the outer surface of the aluminum alloy heat dissipation mesh sleeve and the inner wall of the aluminum alloy thermal conductive sleeve are fitted together, so that the heat generated by the LED lamp body on the lamp holder can be transferred to the aluminum alloy thermal conductive sleeve through the aluminum alloy heat dissipation mesh sleeve, and then transferred to the aluminum alloy heat sink through the aluminum alloy thermal conductive sleeve. When the air flow flows from the through-hole into the air outlet, the heat can be taken away from the aluminum alloy thermal conductive sleeve and the aluminum alloy heat sink, thereby playing a role in heat dissipation. At the same time, it avoids direct contact between air and the installation part of the LED lamp body, preventing dust and impurities from contaminating the connection and installation parts of the LED lamp body.

[0015] 2. Close one end of the aluminum alloy thermal sleeve, and extend the through-hole to the closed end of the aluminum alloy thermal sleeve, so that when the airflow blows toward the aluminum alloy thermal sleeve, it can be better directed into the through-hole. Fix the motor inside the mounting sleeve through a support rod. When the motor rotates, it can drive the fan blades to blow the external airflow into the interior of the mounting sleeve. At the same time, a filter is set inside the rear end cover to filter the air.

A through-hole 11 penetrating to one side of the closed end is provided on the side wall of the aluminum alloy heat-conducting sleeve 8. A plurality of air outlets 10 are equidistantly provided on the inner wall of the through-hole 11. One end of each of the plurality of air outlets 10 penetrates to one side of the aluminum alloy heat sink 9, so that when the air flow flows from the through-hole 11 into the air outlet 10, it can take away the heat from the aluminum alloy heat-conducting sleeve 8 and the aluminum alloy heat sink 9, thereby achieving the purpose of heat dissipation.

[0029] In order to facilitate the blowing of external air into the installation sleeve 2, a plurality of support rods 13 are fixed equidistantly along the circumferential direction between the inner walls of the installation sleeve 2 near one side edge. A motor 14 is fixed between one end of the plurality of support rods 13. A plurality of fan blades 15 are fixed equidistantly along the circumferential direction at the output end of the motor 14.
