Description

Technical Field

[0001] This utility model relates to a heat dissipation installation structure for lamp groups in long row lights. Background Technology

[0002] Long array lights are typically mounted on the roof of vehicles. Due to the need for sealing and waterproofing, their heat dissipation performance is insufficient, and the heat generated by the light assembly inside the lamp housing tends to accumulate there. To solve this problem, existing methods use a metal heat dissipation cap connected to a metal heat conduction plate. This heat conduction plate passes through a waterproof heat dissipation channel and makes thermal contact with a metal profile plate on the bottom flap of the long array light, achieving reliable heat conduction. However, in these long array lights, the metal heat dissipation cap and heat conduction plate are designed as a single piece, resulting in poor heat conduction efficiency and inconvenient disassembly and assembly of the light assembly. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the existing technology and provide a heat dissipation structure for a long row of lights with good thermal conductivity and convenient assembly and disassembly.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A heat dissipation mounting structure for a long row of lamps includes a lamp housing and a heat conduction component located at the rear end of the lamp assembly. A metal profile plate is provided on the outer bottom surface of the bottom flap of the lamp housing. A mounting base and heat dissipation holes leading to the metal profile plate are formed on the inner side of the bottom flap of the lamp housing. The heat dissipation holes are covered by the metal profile plate. The heat conduction component is fixed to the mounting base. The heat conduction component includes a heat conduction plate and a metal heat conduction cover plate covering the rear end of the lamp assembly. The heat conduction plate includes a horizontal plate and a vertical plate, with the horizontal plate fixed to the mounting base. The vertical plate of the heat conduction plate passes through the heat dissipation holes and makes thermal contact with the metal profile plate. The feature is that the metal heat conduction cover and the heat conduction plate are set separately. The horizontal plate of the heat conduction plate extends to form a contact heat conduction plate. The metal heat conduction cover is formed with a lamp assembly mounting plate. The lamp assembly mounting plate is perpendicular to the metal heat conduction cover and arranged in an L-shape. The lamp assembly mounting plate is detachably installed on the positioning seat. The lamp assembly mounting plate is stacked on the contact heat conduction plate of the horizontal plate to achieve contact heat conduction.

[0006] Preferably, a plurality of vertical heat dissipation baffles are distributed at intervals in the space between the lamp mounting plate and the metal heat-conducting cover, and the vertical heat dissipation baffles are integrally formed and connected to the lamp mounting plate and the metal heat-conducting cover.

[0007] Preferably, the edge of the vertical heat dissipation partition is arc-shaped from the end connected to the lamp mounting plate to the end connected to the metal heat-conducting cover plate.

[0008] Preferably, the contact heat-conducting plate is provided with a positioning through hole, and the lamp assembly mounting plate is provided with a stepped connecting hole. The diameter of the bottom hole of the stepped connecting hole is larger than the diameter of the top hole. The mounting base is provided with a screw connecting post, and a screw is threaded onto the screw connecting post. The screw connecting post passes through the positioning through hole and is inserted into the bottom hole of the stepped connecting hole. After the screw is inserted into the top hole of the stepped connecting hole, it is threaded onto the screw connecting post, thereby pressing the lamp assembly mounting plate onto the contact heat-conducting plate.

[0009] By adopting the above technical solution, the heat conduction component is designed as a separate unit, allowing the lamp assembly to be disassembled and installed independently of the heat conduction plate, facilitating lamp assembly assembly and disassembly. Furthermore, the metal heat-conducting cover and heat conduction plate on the lamp assembly use overlapping contact heat conduction, resulting in a larger contact area, thereby effectively improving heat conduction efficiency and heat dissipation performance. Since the metal heat-conducting cover and heat conduction plate are separated to form the lamp assembly mounting plate, it is beneficial for the design of vertical heat dissipation partitions, thus enabling the lamp assembly to have a larger heat dissipation area and improving its heat dissipation performance.

[0010] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0018] See appendix Figures 1-7This utility model discloses a heat dissipation mounting structure for a long row of lamps, including a lamp housing 1 and a heat conduction component located at the rear end of the lamp assembly 2. A metal profile plate 12 is provided on the outer bottom surface of the bottom flap 11 of the lamp housing 1. A mounting base 111 and heat dissipation holes 112 leading to the metal profile plate 12 are formed on the inner side of the bottom flap 11 of the lamp housing 1. The heat dissipation holes 112 are covered by the metal profile plate 12. The heat conduction component is fixed to the mounting base 111. The heat conduction component includes a heat conduction plate 22 and a metal heat conduction cover 21 covering the rear end of the lamp assembly 2. The lamp panel inside the lamp assembly 2 is attached to the metal heat conduction cover 21. The heat conduction plate 22 includes a horizontal plate 221 and a vertical plate 222. The horizontal plate 221 is fixed to the mounting base 111. After passing through the heat dissipation hole 112, the vertical plate 222 makes thermal contact with the metal profile plate 12. To ensure reliable contact between the vertical plate and the metal profile plate, the end of the vertical plate 222 is usually horizontally flipped and extended with a flat end plate 223 for contact. The metal heat-conducting cover plate 21 and the heat conduction plate 22 are separately arranged. The horizontal plate 221 of the heat conduction plate 22 extends with a contact heat-conducting plate 2211. The metal heat-conducting cover plate 21 is formed with a lamp assembly mounting plate 211. The lamp assembly mounting plate 211 is perpendicular to the metal heat-conducting cover plate 21 and arranged in an L-shape. The lamp assembly mounting plate 211 can be detachably installed on the positioning seat 111. The lamp assembly mounting plate 211 is stacked on the contact heat-conducting plate 2211 of the horizontal plate 221 to achieve contact heat conduction. The heat conduction components adopt a split design, allowing the lamp assembly to be disassembled and installed independently of the heat conduction plate, which facilitates the disassembly and assembly of the lamp assembly. Moreover, the metal heat conduction cover and heat conduction plate on the lamp assembly adopt a stacked contact heat conduction, which has a larger contact area, thereby effectively improving the heat conduction efficiency and heat dissipation performance.

[0019] A plurality of vertical heat dissipation baffles 212 are spaced apart within the included angle space between the lamp mounting plate 211 and the metal heat-conducting cover plate 21. The vertical heat dissipation baffles 212 are integrally formed and connected to the lamp mounting plate 211 and the metal heat-conducting cover plate 21. The vertical heat dissipation baffles can improve the heat dissipation performance of the lamp assembly. The edge 2121 of the vertical heat dissipation baffle 212 from the end connected to the lamp mounting plate 211 to the end connected to the metal heat-conducting cover plate 21 is arc-shaped.

[0020] In this specific embodiment, the contact heat-conducting plate 2211 is provided with a positioning through hole 2212, and the lamp assembly mounting plate 211 is provided with a stepped connecting hole 2111. The diameter of the bottom hole 21111 of the stepped connecting hole 2111 is larger than the diameter of the top hole 21112. The mounting base 111 is provided with a screw connecting post 1111, and a screw 3 is threaded onto the screw connecting post 1111. The screw connecting post 1111 passes through the positioning through hole 2212 and is inserted into the bottom hole 21111 of the stepped connecting hole 2111. After the screw 3 is inserted into the top hole 31112 of the stepped connecting hole 2111, it is threaded onto the screw connecting post 1111, thereby pressing the lamp assembly mounting plate 211 onto the contact heat-conducting plate 2211. The screw connecting post 1111 is used for positioning the contact heat-conducting plate 2211. The top of the screw connecting post 1111 is inserted into the bottom hole of the stepped connecting hole 2111 to achieve pre-positioning during lamp assembly installation. After screwing in, the lamp assembly mounting plate is pressed firmly onto the contact heat-conducting plate, completing the lamp assembly installation. The lamp assembly is installed firmly and reliably, and the contact between the lamp assembly mounting plate and the contact heat-conducting plate is reliable. The stepped connecting hole is usually located between the vertical heat dissipation baffles 212. With the rounded edge design of the vertical heat dissipation baffles 2121, the vertical heat dissipation baffles avoid obstructing the tools for tightening screws, facilitating the screw tightening operation.

Those skilled in the art, under the guidance of this utility model, can make corresponding changes to the above embodiments, such as... Figure 1 and Figure 2 As shown, the heat conduction plates corresponding to the lamp groups at different locations can have various shapes. Therefore, all equivalent embodiments fall within the protection scope of this utility model.
