[0030] Please refer to Figure 1 and Figure 2As shown, the present application first provides a lighting structure mounted on a device main body, the device main body comprising an inner container 100 and a side plate 200 fixed to each other, the lighting structure being arranged between the inner container 100 and the side plate 200, comprising a lamp body 10 and a heat insulation assembly 20, the heat insulation assembly 20 comprising a first heat preservation layer 21, a second heat preservation layer 22 and a heat insulation cover 23, the lamp body 10 and the first heat preservation layer 21 are both fixed to the outer wall of the inner container 100, the first heat preservation layer 21 is provided with a first through hole, and the lamp body 10 penetrates through the first through hole; the second heat preservation layer 22 is provided with a second through hole corresponding to the lamp body 10 and is sleeved on the outside of the lamp body 10, and the projection of the second heat preservation layer 22 along the irradiation direction of the lamp body 10 covers the first through hole; the heat insulation cover 23 is fixed to the side plate 200 and is provided with a third through hole, part of the lamp body 10 penetrates through the third through hole into the heat insulation cover 23, the second heat preservation layer 22 is located between the first heat preservation layer 21 and the heat insulation cover 23, and the heat insulation cover 23 is at least partially located in the first through hole to cooperate with the lamp body 10 to press and fix the second heat preservation layer 22 along the irradiation direction.

[0032] Specifically, after the second heat preservation layer 22 is sleeved on the lamp body 10 through the second through hole, the lamp body 10 can provide radial direction limiting, and when the side plate 200 is installed, the heat insulation cover 23 on the side plate 200 will press the second heat preservation layer 22, cooperating with the lamp body 10 to fix the second heat preservation layer 22 along the axial direction (i.e. the irradiation direction), at this time, the second heat preservation layer 22 corresponding to the first through hole is recessed in the first through hole, and the rest of the second heat preservation layer 22 is close to the first heat preservation layer 21 away from the inner container 100 side, thereby completing the plugging of the first through hole to prevent the heat from spreading outward through the first through hole. Figure 2 The contact part of the second heat preservation layer 22 and the first heat preservation layer 21 is misaligned, and the second heat preservation layer 22 is actually attached to the first heat preservation layer 21 away from the inner container 100 side.
[0033] More specifically, the material of the heat insulation cover 23 is high-temperature-resistant plastic or other high-temperature-resistant material.

[0036] Preferably, after the side plate 200 is fixed, the distance between the heat shield 23 and the stepped surface 122 along the irradiation direction is less than the initial thickness of the second thermal insulation layer 22, so that the second thermal insulation layer 22 can be deformed by being pressed, thereby achieving more reliable fixation.
[0037] As shown in Figure 1 and Figure 2 As shown, in some embodiments, the outer wall of the light guide cylinder 12 is further provided with a tapered surface 123, the tapered surface 123 is located on the side of the stepped surface 122 away from the inner container 100, and the diameter of the tapered surface 123 gradually increases towards the side close to the inner container 100 along the irradiation direction, the tapered surface 123 can play a guiding role, so as to facilitate the second thermal insulation layer 22 to be set on the outer side of the light guide cylinder 12.
[0038] As shown in Figure 1 and Figure 2 As shown, in some embodiments, the inner wall of the light guide channel 121 is further fixed with a light guide column 14, one end of the light guide column 14 is opposite to the lamp beads 111, and the other end is opposite to the window glass 13.
[0039] The light emitted by the lamp beads 111 is emitted from the other end of the light guide column 14 after the light guide action of the light guide column 14 and is emitted to the window glass 13, at this time, the other end of the light guide column 14 can be regarded as the actual light source of the lighting structure of the present application, therefore, the present application shortens the distance between the light source and the window glass 13 through the light guide column 14 under the premise that the positions of the lamp panel 11 and the window glass 13 are unchanged, thereby reducing the illumination dead angle inside the inner container 100, effectively alleviating the situation of black under the lamp, and improving the lighting effect.
[0040] As shown in Figure 1 and Figure 2As shown, in some embodiments, a light blocking piece 15 is further arranged between the light guide column 14 and the lamp plate 11, the light blocking piece 15 is provided with a lamp bead hole 151 penetratingly arranged outside the lamp bead 111, the diameter of the lamp bead hole 151 gradually increases along the irradiation direction towards the side close to the inner container 100, and the diameter of the lamp bead hole 151 close to the inner container 100 is the same as the diameter of the light guide column 14; so that the light emitted by the lamp bead 111 can be emitted along the light guide column 14 after being reflected and guided by the inner wall of the lamp bead hole 151, thereby minimizing light loss.
[0041] Please refer to Figure 1 and Figure 2 As shown, in some embodiments, the lamp plate 11 is fixed with a heat dissipation fin 16 away from the side of the inner container 100, the heat dissipation fin 16 is opposite to the heat dissipation hole of the side plate 200, so as to improve the heat dissipation capacity of the lamp plate 11 and prevent heat accumulation on the lamp plate 11 and the lamp bead 111.

[0043] Specifically, the window glass 13 is in a stepped shape, and the cross section of the sealing ring 17 is in a U shape.
[0044] In some embodiments, the window glass 13 is frosted glass, so that when the user observes from the inside of the inner container 100, the lamp plate 11 cannot be directly observed, thereby improving the aesthetics of the lighting structure of the present application.
[0045] In some embodiments, the first heat preservation layer 21 is heat preservation cotton, and the second heat preservation layer 22 is fiber cloth. Of course, the first heat preservation layer 21 and the second heat preservation layer 22 can also use other commonly used heat preservation materials, which will not be listed here.
