The PCB board and the focusing protection cover are placed in the formed grooves and fixed to the shell by bolts, and the focusing protection cover is flush with the shell.

[0010] Furthermore, a preferred solution is that an annular retaining bar is provided around the periphery of the heat dissipation plate, which matches the annular shape of the PCB board and is engaged with the edge of the focusing protective cover.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides the following technical solutions:

[0032] See also Figure 1 , Figure 2 and Figure 3The utility model tunnel lamp 1 comprises a shell 12 surrounded by an upper cover encapsulating a tunnel lamp assembly 11, and a lower cover 13, and the power supply circuit and data line of the tunnel lamp 1 are encapsulated in the shell 12;

[0033] The tunnel light assembly 11 includes: a PCB board 112 on which an array of LED light-emitting chips 20 are printed; the light-emitting end faces of the LED light-emitting chips 20 of the PCB board 112 are encapsulated on the LED light-emitting chips 20 through a focusing protective cover 111; the focusing protective cover 111 is integrally formed with an array of lens protrusions 1111 corresponding to the light-emitting position of the LED light-emitting chips; the bottom surface of the PCB board 112 is fitted on a heat dissipation plate 113; the heat dissipation plate 113 is provided with a heat-conducting pipe 1133 filled with a heat transfer or latent heat medium; a mounting plate 1132 extends from both ends of the heat dissipation plate 113 and is fixedly connected to both sides of the tunnel light housing 12.

[0034] Furthermore, the periphery of the light-collecting protective cover 111 is fixedly connected to the heat dissipation plate 113 by bolts 30 , and the PCB board 112 is encapsulated therein.

[0035] Furthermore, both ends of the heat sink 113 are provided with non-closed U-shaped raised protrusions, which form a groove structure with the raised edges of the two opposite sides of the shell 12. The PCB board 112 and the focusing protection cover 111 are placed in the groove and fixed to the shell by bolts 30. In this way, the focusing protection cover 111 and the shell 12 are basically level, which is easier to maintain and clean later.

[0036] Furthermore, the periphery of the heat sink 113 includes an annular retaining bar 1131 that matches the annular shape of the PCB board and is engaged with the edge of the focusing protection cover 111 .

[0037] Furthermore, a rotatable bracket 14 is installed on both sides of the shell 12.

[0038] Specifically, in the present invention, the bracket 14 includes a U-shaped structure support rod 141, which is provided with a screw hole 142 and fixedly connected to the tunnel wall. The free ends on the left and right sides of the U-shaped structure support rod 141 can be rotatably connected to the shell 12.

[0039] Furthermore, the bracket 14 is detachably connected to the shell 12, so that during maintenance, the shell 12 can be directly removed from the bracket 14 and maintained separately, thereby saving maintenance costs.

[0040] In one embodiment, the bracket 14 is connected to the housing 12 via an adjusting nut 143 to adjust the lighting angle of the tunnel light 1 as a whole.

[0041] like Figure 4As shown: three tunnel lights 1 of the present invention are combined into a tunnel light 40 with triple power. Three tunnel light components 11 are connected in an array and encapsulated in one body through a shell 12. The bracket 14 is detachably connected to the shell 12. In this way, a tunnel light 40 with triple power can be obtained by simple combination.

[0042] like Figure 5 As shown: four tunnel lights 1 of the present invention are combined into a tunnel light 50 with 4 times the power through a 2*2 combination method. After the tunnel light assembly 11 is encapsulated by two shells 12 in parallel, the two ends of the shells 12 are respectively connected through a large bracket 14, and the contact parts between the two shells 12 are fixedly connected by plugging.

[0043] like Figure 6 As shown: six tunnel lights 1 of the present invention are combined into a 6-fold power tunnel light 60 in a 2*3 combination mode. First, three tunnel light assemblies 11 are encapsulated in a shell 12, and then two of the above 3*1 structure tunnel lights 1 are connected in parallel to form a 6-fold power tunnel light 60. A large bracket 14 is used to connect the two ends of the shell 12, and the contact parts of the two shells 12 are fixedly connected by plugging.

[0044] For further information, see Figure 7 A closed mesh heat-conducting pipe 1133 is provided between the other sides of the heat dissipation plate 113 , and the heat-conducting pipe 1133 is filled with a heat transfer or latent heat medium.

[0045] Furthermore, the shape of the pipe in the heat-conducting pipe 1133 can be a mesh structure composed of any one of a rectangle, square, polygon or circle. The heat-conducting pipe 1133 is filled with a heat transfer or latent heat medium to reduce the weight of the heat sink 113 and improve the heat transfer efficiency generated by the tunnel lamp assembly 11 when it is working, thereby protecting the tunnel lamp assembly 11 and extending the service life of the tunnel lamp assembly 11.

[0046] Specifically, the mesh heat-conducting pipe 1133 can be formed by processing methods such as inflation, CNC milling machine, etc. The specific heat dissipation principle of the mesh heat-conducting pipe 1133 is described in detail in other patents and will not be repeated here.

[0047] In one embodiment, the heat dissipation plate 113 can be made of stainless steel or aluminum.

[0048] Specifically, since aluminum is not easily oxidized and is lightweight, using aluminum to make the heat dissipation plate 113 can reduce the frequency of maintenance and replacement of the heat dissipation plate 113, reduce the weight of the lamp, and make the mounting bracket 14 more stable and safe.

[0049] Figure 4-Figure 6The utility model adopts a novel array structure, which does not require additional installation space, thus saving installation costs. In addition, multiple tunnel lights can be added or removed when necessary to meet different power requirements, without the need to frequently replace lamps, further simplifying operations and reducing costs.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
