[0027] like Figure 1-3 As shown, the structure of the tunnel lamp in the utility model is similar to the existing tunnel lamp structure, such as the LED street lamp suitable for tunnel lighting disclosed in the patent with publication number CN216307527U. The main improvement of the utility model is to make the tunnel lamp housing self-cleaning to ensure the lighting effect; when the inside of the lamp housing 1 needs to be cooled, the motor 55 and the cooling fan 6 are started, and the cooling fan 6 draws the outside air from the outside of the air intake cover 3 into the cooling pipe network 4, and then transports it from the cooling pipe network 4 to the lamp housing 1, and the heat in the lamp housing 1 is discharged from the cooling pipe network 4. 2 is blown out, the dust in the air is blocked by the heat dissipation network 4, the motor 55 drives the reciprocating screw rod 51 to rotate, the reciprocating screw rod 51 drives the gear 52 to rotate, the gear 52 drives the inner gear ring 53 to rotate, the inner gear ring 53 drives the heat dissipation network 4 to rotate in the air intake cover 3, and the heat dissipation network 4 contacts the cleaning strip 7 fixed on the inner wall of the air intake cover 3 while rotating, the cleaning strip 7 cleans out the dust blocked on the heat dissipation network 4, so as to avoid the dust accumulation affecting the heat dissipation fan 6 to transport gas into the lamp housing 1, the heat dissipation network 2 can prevent mosquitoes from entering the lamp housing 1, and ensure the heat dissipation effect inside the lamp housing 1.

[0028] Among them, the cooling fan 6 and the motor 55 mentioned above can be purchased on the market. They are mature technologies and have been fully disclosed, so they are not repeated in the specification. The cooling fan 6 and the motor 55 are both equipped with power connection lines, and they are electrically connected to the external main controller and the 220V phase voltage (or 380V line voltage) through the power lines, and the main controller can be a conventional known device such as a computer that plays a control role.

[0029] like Figure 3As shown, the driving unit 5 also includes a limiting rod 54, which is fixedly connected to the inner wall of the air intake hood 3, the reciprocating screw 51 and the limiting rod 54 respectively pass through the two ends of the cooling fan 6, the reciprocating screw 51 is threadedly connected to the cooling fan 6, and the cooling fan 6 is slidably connected to the limiting rod 54; when the motor 55 drives the reciprocating screw 51 to rotate, the reciprocating screw 51 drives the cooling fan 6 to move back and forth, the cooling fan 6 and the limiting rod 54 slide, and the limiting rod 54 restricts the cooling fan 6, and the cooling fan 6 moves back and forth in the cooling pipe network 4 and transports air into the lamp housing 1. The moving cooling fan 6 can dissipate heat evenly in the lamp housing 1, improve the heat dissipation effect, and avoid heat accumulation inside the lamp housing 1.

[0030] like Figure 1 , 2 As shown in FIG. 4 , the heat dissipation net 2 corresponds to the position of the air inlet cover 3 ; the air transported into the lamp housing 1 can quickly discharge the heat in the lamp housing 1 from the heat dissipation net 2 , thereby improving the air flow in the lamp housing 1 and ensuring the heat dissipation effect.

[0031] like Figure 1 , 3 As shown, the heat dissipation network 4 blocks the inner wall of the air intake cover 3; the heat dissipation network 4 completely blocks the internal space of the air intake cover 3, which can prevent mosquitoes, dust, etc. from entering the lamp housing 1 through the air intake cover 3 and affecting the operation of the electronic components inside the lamp housing 1, thereby improving practicality.

[0032] like Figure 4 , 5 As shown, an air outlet 8 is opened on the inner wall of the lamp housing 1, and an air guide plate 9 corresponding to the air outlet 8 is fixedly connected to the inner wall of the lamp housing 1, and an air guide cover 10 is fixedly connected to the outer wall of the lamp housing 1; when the cooling fan 6 moves to correspond to the air guide plate 9, the cooling fan 6 conveys the wind out from the air outlet 8 through the guidance of the air guide plate 9, and through the guidance of the air guide cover 10, the blown wind blows the light-emitting surface of the lamp housing 1, so as to avoid dust adhesion affecting the lighting effect and improve practicality.

[0033] like Figure 5 As shown, a plurality of wind dispersing strips 11 are fixedly connected to the air outlet 8; the wind dispersing strips 11 can guide and disperse the wind blown out from the air outlet 8 so that the blown wind does not gather, and the dispersed wind can better clean the outer wall of the lamp housing 1.

[0034] like Figure 1 As shown, a clearance opening 12 is provided on the outer bottom surface of the air inlet hood 3, and the cleaning strip 7 corresponds to the clearance opening 12; the dust cleaned out by the cleaning strip 7 from the heat dissipation pipe network 4 falls from the clearance opening 12 and will not accumulate in the air inlet hood 3, thereby ensuring the cleaning effect.

[0035] The implementation steps in this embodiment are as follows: when it is necessary to dissipate heat inside the lamp housing 1, the motor 55 and the cooling fan 6 are started, the cooling fan 6 draws outside air from the outside of the air intake hood 3 into the cooling pipe network 4, and then transports it from the cooling pipe network 4 to the lamp housing 1, and blows the heat in the lamp housing 1 out from the cooling network 2, and the dust in the air is blocked by the cooling pipe network 4. The motor 55 drives the reciprocating screw 51 to rotate, the reciprocating screw 51 drives the gear 52 to rotate, the gear 52 drives the inner gear ring 53 to rotate, and the inner gear ring 53 drives the cooling pipe network 4 to rotate in the air intake hood 3. While the cooling pipe network 4 rotates, it contacts the cleaning strip 7 fixed on the inner wall of the air intake hood 3, and the cleaning strip 7 cleans out the dust blocked on the cooling pipe network 4, thereby avoiding Dust accumulation affects the gas delivery of the cooling fan 6 into the lamp housing 1. The heat dissipation net 2 can prevent mosquitoes from entering the lamp housing 1, thereby ensuring the heat dissipation effect inside the lamp housing 1. The reciprocating screw 51 drives the cooling fan 6 to move back and forth while rotating. The cooling fan 6 slides with the limit rod 54, and the limit rod 54 limits the cooling fan 6. The cooling fan 6 moves back and forth in the heat dissipation pipe network 4 and delivers air to the lamp housing 1. The moving cooling fan 6 can dissipate heat evenly in the lamp housing 1. When the cooling fan 6 moves to correspond to the air guide plate 9, the cooling fan 6 delivers the wind from the air outlet 8 through the guidance of the air guide plate 9, and through the guidance of the wind dispersion strip 11 and the air guide cover 10, the blown wind blows the light-emitting surface of the lamp housing 1 to clean the dust.

[0036] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
