Description

Technical Field

[0001] The utility model relates to a warning signal lamp, in particular to a long row of signal lamps used on vehicles. Background Art

[0002] At present, the long row of signal lights used in vehicles is generally installed on the top of the vehicle. It includes a shell (including a cover plate and a bottom plate), a light group (including a lampshade), a control circuit board, etc. A switch is installed on the outside of the long row of signal lights. It is connected to the cigarette lighter power supply in the vehicle through the switch power cord to make the light group work and emit light, which plays a good warning role.

[0003] There are two types of mainstream long-row signal light shells: one is a plastic lamp shell, and the other is a combination of aluminum alloy lamp shell and plastic lamp shell. One of the long-row signal lights using aluminum alloy shells is usually made of three pieces (two large and one small) of aluminum alloy shells spliced ​​together, and the upper and lower shells are connected by brackets. The lampshade is a plastic product, which is fixed to the light group by pushing and pulling or using screws. The problems with this long-row signal light are: due to the structural design, the signal light is easy to loosen and not tight as a whole, and the longitudinal connection strength is low, which is not conducive to driving safety and has certain safety hazards; the assembly process is complicated and time-consuming, the production efficiency is low, and it is difficult to disassemble and repair; the heat dissipation efficiency of the light group is low, which cannot meet the high requirements of high-power signal lights; the control circuit board is generally installed in the lower shell, which is easily soaked by the intruding water vapor. Summary of the invention

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a heat dissipation type high-power long row signal light with quick assembly and disassembly, tight connection and good heat dissipation.

[0005] The purpose of the utility model is achieved through the following technical scheme: a heat-dissipating high-power long-row signal light, comprising a cover plate, a base plate, a light group, and a control circuit board, a heat-dissipating bracket is installed on the base plate and at the inner side edge of the light group, a positioning cylinder is installed on the heat-dissipating bracket, and positioning blind holes corresponding to the positioning cylinder are provided on the cover plate and the base plate.

[0006] The control circuit board is mounted on the inner surface of the cover plate through a shock-absorbing rubber pad, which effectively prevents water vapor from entering the signal lamp, and plays a role in shock and collision prevention and is difficult to fall off. The heat dissipation bracket is a plurality of brackets mounted on the inner walls of both sides of the bottom plate, and a connecting bracket is installed on the bottom plate and between the heat dissipation brackets on the inner walls of both sides of the bottom plate, which increases the overall strength. The heat dissipation bracket has a concave structure and is provided with a wire hole, which is more conducive to improving the heat dissipation efficiency and is also convenient for assembling the wires of the lamp group and electrically connecting them with the control circuit board.

[0007] After adopting the structure of the utility model, the heat dissipation bracket is attached to the lamp group, and the heat dissipation bracket is tightly connected to the positioning blind holes on the cover plate and the bottom plate through its positioning cylinder. Through positioning cooperation, assembly and production are simpler, and disassembly and maintenance are more convenient. The cover plate and the bottom plate integrally cover the lamp group to enhance the strength against external forces. The heat of the light source of the lamp group is quickly conducted to the cover plate and the bottom plate through the heat dissipation bracket, which increases the heat dissipation area and significantly improves the heat dissipation efficiency, thereby effectively guaranteeing the power increase of the long row of signal lights, and the brightness of the lamp group can be appropriately increased and the warning effect is more prominent. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The present invention will be described in further detail below in conjunction with the accompanying drawings and implementation examples.

[0010] Reference Figure 1 It can be seen that the utility model heat dissipation type high-power long row signal light includes a cover plate 1, a base plate 2 (both of which are arc-shaped), a lamp group 3, and a control circuit board 6. A heat dissipation bracket 4 is installed on the base plate 2 and at the inner side of the lamp group 3. Positioning cylinders 8 (one each for the left, right, top and bottom) are installed on the heat dissipation bracket 4. Positioning blind holes 7 corresponding to the positions of the positioning cylinders are provided on the cover plate 1 and the base plate 2. Positioning cylinders 8 are installed on the upper and lower end surfaces of the heat dissipation bracket 4 and are respectively assembled corresponding to the positioning blind holes 7 on the cover plate and the base plate.

[0011] The control circuit board 6 (modular) is mounted on the inner surface of the cover plate 1 through a shock-absorbing rubber pad 9, which effectively prevents water vapor from invading the long row of signal lights, and plays a role in shock and collision prevention and is difficult to fall off. The heat dissipation bracket 4 is a plurality of heat dissipation brackets 4 mounted on the inner walls of both sides of the bottom plate 2 (left and right, front and back positions), and connecting brackets 5 (several) are installed on the bottom plate 2 and between the heat dissipation brackets on the inner walls of both sides of the bottom plate (front and back positions) to increase the connection strength. A mounting hole 10 is provided on the cover plate 1 and on the side of the positioning blind hole 7. The mounting hole corresponds to the position of the connecting bracket, which is convenient for the assembly of the cover plate. The heat dissipation bracket 4 has an inner concave structure and is provided with a wire hole 11, which is more conducive to improving the heat dissipation efficiency and is also convenient for assembling the wires of the lamp group 3 and electrically connecting the control circuit board 6.

[0012] The cover plate 1 and the bottom plate 2 are made of the same finely machined aluminum alloy, and the upper and lower sides of the heat dissipation bracket 4 are provided with positioning cylinders 8 (corresponding to the positioning blind holes).
