Description
Technical Field
[0001] This utility model relates to the field of automotive lighting technology, and more specifically to a long strip vehicle light. Background Technology
[0002] Long strip car lights are a new type of automotive lighting device, widely used in the automotive industry due to their unique appearance and excellent performance. For example, Chinese Patent Publication No. CN209116234U discloses a projector-type long strip car auxiliary light, including a heat dissipation housing and a light source module. The heat dissipation housing has a "C" structure, and the connection between the heat dissipation housing and the light source module has a slot with a semi-circular bottom. An adhesive strip is installed inside the slot. A reflector is located below the light source module, and a lens is located in front of the light source module. Waterproof gaskets and connecting plugs are sequentially located at both ends of the light source module. An auxiliary plug is located in front of the connecting plug. The upper and lower ends of the "C" structure of the heat dissipation housing are connected to corners. The auxiliary plugs connect to the left and right sides of the corners and the front end of the connecting plug, respectively. The upper and lower ends of the auxiliary plugs are connected to the heat dissipation housing. This patented structure connects the heat dissipation housing and the light source module through a counter-pressure interference fit using the slot and adhesive strip of the heat dissipation housing, eliminating the need for screws or other connecting parts and increasing production efficiency. However, this technical solution still has the following shortcomings in practical applications: Installation is inconvenient; holes need to be drilled in the roof to fix the heat dissipation shell, which not only damages the integrity of the vehicle structure but also increases installation time. Furthermore, the drilled holes are prone to water seepage due to improper sealing. The appearance is unattractive; the LEDs in the light source module are exposed and can be seen directly from a horizontal viewing angle, which does not meet the modern automotive requirement for "hidden lighting" in auxiliary lights. Functionality is limited; it only provides basic lighting and does not integrate decorative functions such as ambient lighting, failing to meet users' needs for personalized automotive lighting. Stability is insufficient; the light source module is only fixed by adhesive strips and slots, making it prone to displacement during vehicle movement, affecting lighting stability, and it lacks targeted waterproofing and shockproof design. Therefore, there is an urgent need for a long, strip-shaped vehicle light that requires no drilling, has a hidden LED design, is multifunctional, and structurally stable, to overcome the shortcomings of existing technologies. Summary of the Invention
[0003] The purpose of this utility model is to provide a long strip car light with concealed LED beads to overcome the shortcomings of the existing technology. It eliminates the need for drilling holes in the roof, conceals the LED beads for an aesthetically pleasing appearance, and also features waterproof, shockproof, efficient heat dissipation, and ambient lighting functions, thereby improving installation convenience and user experience.
[0004] This utility model achieves the above-mentioned objectives using the following technical solution: a long strip car light with concealed LED beads, characterized in that it includes a fixed bracket, a heat dissipation back shell, a main LED bead plate, a side light-emitting cup, and a light-transmitting plate. The fixed bracket is connected to the heat dissipation back shell and can be used for installation of round tubes without the need for drilling holes in the roof. The heat dissipation back shell is provided with a cavity for accommodating the main LED bead plate and the side light-emitting cup. The cavity has an opening, and the light-transmitting plate is installed at the opening, so that the main LED bead plate and the side light-emitting cup can be encapsulated inside the heat dissipation back shell. The side light-emitting cup is located above the main LED bead plate, and a through hole is provided at the bottom of the light-emitting cup to allow light to pass through, so that the LED bead can be hidden below the light-emitting cup. The light emitted by the LED bead of the main LED bead plate enters the side light-emitting cup through the through hole, and then is reflected or refracted by the side light-emitting cup and emitted from the light-transmitting plate. The LED bead cannot be directly seen from a horizontal viewing angle, thus improving the aesthetic appearance.
[0005] As a further explanation of the above scheme, an upper slot and a lower slot are respectively provided at the upper and lower ends of the cavity opening, and the light-transmitting plate is inserted between the upper slot and the lower slot; an upper sealing strip is provided on the inner side of the upper slot, and an upper pressure bar is provided on the outer side, with the upper sealing strip and the upper pressure bar respectively tightly attached to both sides of the light-transmitting plate; a lower sealing strip is provided on the inner side of the lower slot, and a lower pressure bar is provided on the outer side, with the lower sealing strip and the lower pressure bar respectively tightly attached to both sides of the light-transmitting plate; this allows the light-transmitting plate to be inserted between the slots, the sealing strip to be tightly attached to the light-transmitting plate to achieve a seal, and the pressure bar to further press the light-transmitting plate to prevent loosening.
[0006] Furthermore, the upper and lower sealing strips are L-shaped, which, compared to straight sealing strips, can simultaneously adhere to the inner wall of the slot and the edge of the light-transmitting plate, increasing the contact area by more than 30%, improving the waterproof and anti-fog effect, and preventing fogging inside the cavity from affecting light transmittance due to temperature differences.
[0007] Furthermore, a vertical pressure plate is provided at the bottom of the side light-emitting cup. The vertical pressure plate presses against the main lamp bead plate, increasing the support position, fixing it better, and preventing vibration and displacement.
[0008] Furthermore, an ambient light panel is provided at the rear of the cavity of the heat dissipation shell, and a light-transmitting slit is provided on the side light cup. An ambient light guide strip is embedded in the light-transmitting slit. The light emitted by the ambient light panel is guided out through the light guide strip, realizing the dual functions of lighting and ambient decoration.
[0009] Furthermore, the upper and lower edges of the side light-emitting cup are provided with bent edges, and protruding edges are provided outside the upper and lower slots respectively. The protruding edges are provided with positioning grooves. The bent edges of the side light-emitting cup are embedded in the positioning grooves to achieve precise positioning of the side light-emitting cup and avoid shaking.
[0010] Furthermore, the upper and lower sides of the heat dissipation rear shell are respectively provided with an upper pipe clamp mounting slot and a lower pipe clamp mounting slot. The fixing bracket includes a pipe clamp assembly connected between the upper and lower pipe clamp mounting slots. Heat dissipation fins are provided on the back of the heat dissipation rear shell, which can increase the heat dissipation area, quickly dissipate the heat generated by the main lamp board and ambient light board during operation, and extend the service life of the lamp. Pipe clamp rubber blocks are movably provided on the heat dissipation fins. The pipe clamp rubber blocks and the pipe clamp assembly form a locking ring structure for the round tube, which can be used for the installation of 1.5-2 inch round tubes.
[0011] Furthermore, the pipe clamp assembly includes an upper C-type pipe clamp and a lower C-type pipe clamp, which are connected and fixed to each other. The end of the upper C-type pipe clamp is locked to the upper pipe clamp mounting groove by bolts; the end of the lower C-type pipe clamp is locked to the lower pipe clamp mounting groove by bolts, forming a flexible clamp for the round pipe, which ensures the installation is firm and avoids the round pipe being damaged.
[0012] Furthermore, the heat dissipation shell has integrated end caps at both ends, with sealing rings inside the end caps for good waterproofing.
[0013] The beneficial effects that this utility model can achieve by adopting the above-mentioned technical solution are:
[0014] 1. This utility model adopts a long strip car light structure mainly composed of a fixed bracket, a heat dissipation back shell, a main lamp bead plate, a side light cup, and a light-transmitting plate.

The lamp beads cannot be directly seen from a horizontal viewing angle, thus improving the aesthetic appearance.
[0016] 3. This utility model adopts a method of installing the light-transmitting plate on the slot of the heat dissipation rear shell by plugging it in. A sealing strip is provided on the inner side of the slot and a pressure bar is provided on the outer side.
