Tunnel lights consist of a lamp housing, light source, driver, and bracket. During installation, the bracket is fixed to the inner wall of the tunnel. Existing tunnel lights mostly use die-cast radiators or fin-type profile radiators. Although these radiators can meet general heat dissipation requirements, due to poor air circulation in the tunnel, the heat dissipation performance of tunnel lights is very limited under the same power conditions. This is not conducive to the long-term operation of tunnel lights, and their heat dissipation and practicality are limited, making it difficult to meet market demand. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0030] See Figures 1 to 6 As shown, a full-convection, low-temperature-rise tunnel light comprises a heat sink structure, a driver fixed to the heat sink structure, and a light source connected to the driver. In this embodiment, the driver and light source are conventional structures in the prior art, and the installation method is also conventional, so detailed description is omitted for simplicity. Furthermore, in this embodiment, the heat sink structure comprises an N-shaped top shell 1, a trumpet-shaped bottom shell 2, and two end caps 3. In this embodiment, the trumpet-shaped bottom shell is a heat spreader structure, ensuring uniform heat conduction and heat generation. The N-shaped top shell, trumpet-shaped bottom shell, and end caps are all metal structures.

[0031] During assembly, the trumpet-shaped bottom shell snaps onto the lower portion of the n-shaped top shell, and the end caps are screwed to the sides of the n-shaped top shell and trumpet-shaped bottom shell. To enhance full convection heat dissipation, the end caps are provided with first convection channels 4, the symmetrical side walls of the trumpet-shaped bottom shell are provided with second convection channels 5, and the top wall of the n-shaped top shell and the bottom wall of the trumpet-shaped bottom shell are provided with third convection channels 6. This convection heat dissipation in three different directions, creating convection heat dissipation along the X, Y, and Z axes, reduces heat dissipation resistance and improves heat dissipation stability and reliability.

[0032] In actual use, the first convection channel includes a central axial hole 41 in the middle of the end cap, several semicircular convection slots 42, and several enhanced air convection channels 43. During processing, the semicircular convection slots are symmetrically arranged about the vertical centerline of the central axial hole. The enhanced air convection channels are located above the central axial hole. The enhanced air convection channels are arranged in a triangular shape. This structure improves the effectiveness and reliability of air diversion and heat dissipation.

[0033] At the same time, in actual application, the second convection channel is an inclined long convection hole, and the inclined long convection hole is set at an 80-degree angle. The inclined direction is used to increase the length of the inclined long convection hole and improve the heat dissipation performance, and it is inclined at an 80-degree angle to the bottom edge of the trumpet-shaped bottom shell. Figure 3 shown.

[0034] Moreover, in actual application, the third convection channel is a waist-shaped hole.

[0035] In actual application, in order to improve the convenience and effectiveness of assembly, an L-shaped block 7 is integrally formed at the bottom of the n-shaped top shell; an L-shaped slot 8 is fixed to the top of the trumpet-shaped bottom shell; in this embodiment, the vertical opening of the L-shaped slot is 1.6mm, the horizontal opening is 1.8mm, and the opening of the L-shaped slot is rounded, which is conducive to the convenience and effectiveness of the assembly of the L-shaped block. The thickness of the L-shaped block is 1mm, and the outer edge of the L-shaped block is set at an angle. The angle and the L-shaped slot are non-interfering. During assembly, the surface friction when the two are connected can be reduced. After snapping, the 0.3mm gap between the L-shaped block and the L-shaped slot can provide buffering during vibration, prevent falling off, and improve the stability and reliability of use. During assembly, the lower part of the L-shaped block is clamped in the L-shaped slot to limit the position.

[0036] To enhance the ease and effectiveness of end cap assembly, C-shaped screw holes 9 are integrally formed on the inner walls of the N-shaped top shell and the trumpet-shaped bottom shell. The screws of the end caps are threaded into these C-shaped screw holes. Fishbone grooves 10 are also provided on the surfaces of both the N-shaped top shell and the trumpet-shaped bottom shell. These grooves are primarily used to increase the contact area with air.

[0037] The utility model has positive effects: the structure of the utility model is reasonably arranged, a first convection channel is arranged on the end cover, a second convection channel is arranged on the symmetrical side walls of the trumpet-shaped bottom shell, and a third convection channel is arranged on the top wall of the N-shaped top shell and the bottom wall of the trumpet-shaped bottom shell, thereby forming full convection heat dissipation in the X, Y and Z axis directions, reducing heat transfer resistance, being conducive to reducing temperature rise, and increasing the service life of the lamp, thereby improving the stability of use and heat dissipation reliability of the overall structure, and having strong applicability and good practicality.

[0038] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
