Description

Technical Field

[0001] The utility model relates to a warning lighting lamp, which belongs to vehicle lighting warning equipment. Background Art

[0002] At present, on engineering vehicles, lighting lamps and warning lights are often combined together to reduce the number of components and facilitate installation and use by the main engine manufacturer. For example, the "LED warning lighting work light" disclosed in Chinese patent CN213630327U has two lighting lamps hingedly installed at the two ends of the warning light to form an integral structure. However, in actual use, it was found that the hinged structure is not convenient for installation and use, and the LED light-emitting body is sealed and protected by glue. After long-term use, the sealant will age, resulting in a loss of lighting effect and a poor sealing effect. For this reason, there is also Chinese patent CN204153744U that discloses an "LED lighting lamp", which uses a circuit board with an LED light-emitting body installed in a shell with a plastic structure to ensure the sealing effect and avoid the subsequent lighting effect being affected by the aging of the sealant. However, the shell of the integral structure can only be made of transparent plastic to ensure the light transmission effect. Although a metal heat dissipation structure is used inside, the poor thermal conductivity of the plastic shell greatly affects its heat dissipation performance. For this reason, there is an urgent need for a warning lighting lamp that can solve the above problems. Summary of the Invention

[0003] The purpose of the present utility model is to overcome the above-mentioned shortcomings and provide a warning lighting lamp. By combining a metal shell with a transparent lampshade, the problem of balancing light emission and heat dissipation is solved. The double sealing method of the sealed connection through the hook-and-slip sealing groove and the addition of sealant also ensures the sealing effect.

[0004] The purpose of this utility model is achieved in this way:

[0005] A warning lighting lamp includes a heat-conducting shell and end covers installed at both ends of the heat-conducting shell. A mounting plate is installed in the middle of the strip-shaped heat-conducting shell, and a circuit board is attached to the upper surface of the mounting plate. A light-emitting body is installed on the circuit board. Mounting grooves 1 and 3 are provided on the upper parts of the inner walls on both sides of the heat-conducting shell. The two side edges of the circuit board and the lampshade are respectively inserted into the mounting grooves 1 and 3. The two sides of the lampshade are concave near the edges to form sealing grooves. The open end of the groove wall of the mounting groove 3 is folded inward to form a flange embedded in the inner sealing groove.

[0006] Preferably, a plurality of heat dissipation fins are provided on the lower surface of the mounting plate.

[0007] Preferably, silica gel is poured into the sealing groove and solidified to form a sealing strip filling between the third installation groove and the sealing groove.

[0008] Preferably, a light-distributing plate is further provided on the upper part of the inner walls on both sides of the heat-conducting shell, and a reflective bowl is provided between the light-distributing plate and the light-emitting body. The reflective bowl and the light-distributing plate form an integrated structure, or form a light module structure together with the light-emitting body.

[0009] Preferably, the side surface of the end cover is provided with mounting grooves for corresponding insertion of the heat-conducting housing, the circuit board, the light-distributing plate and the lampshade.

[0010] Preferably, the cables introduced into the end cover enter from the side of the heat-conducting housing and are connected to the circuit board, or the cables introduced from the connection terminals on the back of the heat-conducting housing pass through the mounting plate and are connected to the circuit board.

[0011] Preferably, the heat-conducting housing is made of metal aluminum.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model improves the heat dissipation performance through the heat-conducting shell made of metal material, and covers the lampshade above the light-emitting body or the reflective bowl instead of the conventional sealing method, thereby avoiding the influence of sealing and light transmission performance due to aging of the glue; finally, the sealing performance of the edge gap is ensured by the hook-and-edge matching structure of the installation groove and the flange and the silicone injected into the installation groove, thereby achieving higher sealing performance while taking into account both light emission and heat dissipation.

[0025] The mounting plate 1.1 is located on one side of the heat dissipation cavity and is provided with a plurality of heat dissipating fins 1.2. The circuit board 2 is an aluminum substrate, so that the heat generated by the light-emitting body 2.1 during operation can be quickly introduced into the mounting plate 1.1 and then dissipated into the heat dissipation cavity through the heat dissipating fins 1.2, and finally dissipated to the outer wall through the shell wall of the heat-conducting shell 1.1.

The cables on the circuit board 2 are then connected to the end caps 7. The end caps 7 are then secured to the ends of the thermal housing 1 using bolts threaded into mounting holes 1.3. Finally, silicone is poured into the sealing slots 4.1 and cured to seal. The sides of the end caps 7 are also provided with corresponding mounting slots for the thermal housing 1, circuit board 2, light diffuser 3, and lampshade 4 to ensure a secure connection.
