Description

Technical Field

[0001] The present application relates to the field of vehicle lamps, and in particular to a ground edge lamp. Background Art

[0002] Edge lights are usually installed on the side of the truck body, mainly for lighting and signaling, and usually serve as a warning to other vehicles.

[0003] Existing ground edge lights are usually installed on a mounting plate with a flat structure. The mounting plate is provided with heat dissipation holes whose axes are perpendicular to the mounting plate. The light source circuit board in the ground edge light is in contact with the surface of the mounting plate. This makes it possible for the lamp beads on the light source circuit board to be in working state, and the heat generated by them is mostly dissipated through the heat dissipation holes on the mounting plate, thereby achieving the heat dissipation effect.

[0004] However, since the light source board and the mounting plate are in close contact with each other, only a few positions on the light source board near the heat dissipation holes can be directly in contact with the air, so the heat dissipation efficiency is relatively high. However, most positions far away from the heat dissipation holes are in close contact with the mounting plate and rely on the thermal conductivity of the mounting plate to dissipate heat, so the heat dissipation efficiency is relatively low. This reduces the upper limit of the power that the light power board can carry within the maximum power, and also limits the number of lamp beads that can be installed on the light power board, which will make the brightness of the ground edge lights lower. When the vehicle is driving in foggy weather with poor visibility, especially if the vehicle has not been cleaned for a long time and the ground edge lights are partially covered with dust, it is even more likely that the ground edge lights will not be bright enough and thus fail to serve as a warning. Utility Model Content

[0005] In order to improve the brightness of a ground edge light, the present application provides a ground edge light.

[0006] The present application provides a ground edge lamp, which adopts the following technical solution:

[0008] Preferably, a heat dissipation port is provided on the heat dissipation part, the heat dissipation port runs through the heat dissipation part, the extension direction of the heat dissipation port is parallel to the length direction of the vehicle body, and an opening is provided on the lampshade. When the lampshade is installed on the mounting plate, the heat dissipation port is connected to the outside through the opening.

[0009] Preferably, the side light body also includes an optical inner lampshade and a refraction component, and the refraction component, the optical inner lampshade and the light source board are sequentially installed on the lampshade, and the refraction component includes a refractor, which is used to refract the light emitted by the lamp beads on the light source board to the ground.

A refraction part is arranged on a side of the reflector close to the lampshade, and the refraction part is used to refract light incident from the outside into the lampshade.

[0011] Preferably, both ends of the reflector are provided with mounting grooves, and both ends of the refractor are provided with connecting parts at positions corresponding to the mounting grooves, and the connecting parts are slidably installed in the mounting grooves.

[0012] Preferably, when the lampshade is mounted on the mounting plate, the angle between the extending direction of the mounting groove and the horizontal plane is 45°.

[0013] Preferably, a threading hole is provided on the mounting plate.

[0014] Preferably, the mounting plate is provided with a threading hole, and the threading hole is located in the extension direction of the heat dissipation port.

[0015] In summary, compared with the prior art, the advantages of the present application are:

[0016] By providing a heat dissipation portion protruding from the surface of the mounting plate, when the lampshade is mounted on the mounting plate, the light source board abuts against the heat dissipation portion on the mounting plate, so that a portion of the light source board that is not abutted against the heat dissipation portion can leave a gap with the mounting plate. When the lamp beads on the light source board are in working condition, heat can be transferred through the light source board to the gap between the board and the mounting plate, and then dissipated through the heat dissipation holes on the mounting plate. Compared with the method in which the light source board is directly attached to the mounting plate, the light source board can have a larger area for simultaneous heat dissipation, which improves the heat dissipation efficiency of the light source board and also enables the light source board to install more lamp beads within the rated power, thereby achieving the effect of increasing brightness.

[0023] The following is combined with Figure 1-5 This application is described in further detail.

[0024] Embodiment 1 of the present application discloses a ground edge lamp, referring to Figure 1 and Figure 2 , including a mounting plate 1 and a side lamp body 2, the mounting plate 1 is provided with a heat dissipation hole 101 and a threading hole 104, the side lamp body 2 includes a lampshade 201 and a light source electric board 202, the light source electric board 202 is installed in the lampshade 201, a plurality of lamp beads are evenly distributed on the side of the light source electric board 202 close to the lampshade 201, a heat dissipation portion 102 protruding from the surface of the mounting plate 1 is provided on the side of the mounting plate 1 close to the lampshade 201, when the lampshade 201 is fixedly mounted on the mounting plate 1, the power of the light source electric board can first be transmitted through the threading hole 104 to be connected with the external power supply, and the heat dissipation portion 102 can be abutted against the light source electric board 202 installed in the lampshade 201, which makes the lamp There can be a gap between the light source board 202 and other positions on the mounting plate 1 except the heat dissipation part 102, and then when the lamp beads on the light source board 202 are in working state, the heat can be transferred to the gap between the light source board 202 and the mounting plate 1 through the light source board 202, and then dissipated through the heat dissipation holes 101 on the mounting plate 1. Compared with the method in which the light source board 202 is directly attached to the mounting plate 1, this increases the contact area between the light source board 202 and the air, so that the light source board 202 can have a larger area for simultaneous heat dissipation, which plays a role in improving the heat dissipation efficiency of the light source board 202, and then more lamp beads can be installed on the light source board 202, thereby achieving the effect of increasing brightness.

[0025] The side light body 2 also includes an optical inner lampshade 203 and a refractive component 204. The refractive component 204, the optical inner lampshade 203 and the light source component are sequentially installed in the lampshade 201 and fixed by gluing, and finally fixed on the mounting plate 1 through the lampshade 201, wherein the refractive component 204 includes a refractor 2041 and a reflector 2042. The reflector 2042 is installed in the lampshade 201, and the refractor 2041 is installed on the side of the reflector 2042 away from the lampshade 201. The refractor 2041 is used to refract the light emitted by the lamp beads at the bottom end of the light source board 202 to the ground. This allows the light generated by the lamp beads to be refracted to the ground after being refracted by the refractor 2041 when the lamp beads are in working state, thereby being able to indicate the width of the vehicle body, making the vehicle body safer during driving.

[0026] A refraction portion 2043 is further provided on the side of the reflector 2042 close to the lampshade 201. The refraction portion 2043 is composed of a plurality of smooth pyramids. When external light passes through the lampshade 201 and shines on the refraction portion 2043, the light will be diffusely reflected and then emitted from the lampshade 201, so that vehicles next to the vehicle body can avoid the vehicle body in time, further enhancing the warning effect on other vehicles.

[0027] Reference Figure 2 and Figure 3 Furthermore, mounting grooves 2044 are respectively provided at both ends of the returner 2042, and connecting parts 2045 are respectively provided at the positions of the mounting grooves 2044 at both ends of the refractor 2041. The connecting parts 2045 are slidably arranged in the mounting grooves 2044, which makes the disassembly and assembly between the refractor 2041 and the returner 2042 more convenient than bolt connection and other methods.

[0028] Reference Figure 3 and Figure 4 The mounting groove 2044 is inclined and an angle ɑ is formed between the extension direction of the mounting groove 2044 and the horizontal plane, and the angle ɑ is 45°. This allows the light emitted by the lamp beads on the light power board to be refracted onto the ground through the refractor 2041, thereby being able to more accurately feedback the width of the vehicle projected onto the ground, so that the following vehicle can accurately judge the distance when overtaking, thereby reducing the probability of vehicle collision accidents.

[0029] The implementation principle of Example 1 of the present application is: first install the refractor 2041 on the reflector 2042, then install the reflector 2042 on the lampshade 201, and then install the optical inner lampshade 203 and the lamp light source board 202 on the lampshade 201 in turn, and then pass the power cord on the lamp light source board 202 through the threading hole on the mounting plate 1 and then install the lampshade 201 on the mounting plate 1. At this time, the lamp light source board 202 is abutted against the heat dissipation part 102 on the mounting plate 1, and the heat dissipation part 102 protruding from the surface of the mounting plate 1 makes a gap between the lamp light source board 202 and the surface of the mounting plate 1, thereby increasing the heat dissipation area of ​​the lamp light source board 202 on the mounting plate 1, thereby achieving the effect of increasing the heat dissipation efficiency of the lamp light source board 202.

[0030] Reference Figure 5 The difference between the embodiment 2 of the present application and the embodiment 1 is that the heat dissipation portion 102 on the mounting plate 1 in the embodiment 2 of the present application is provided with a heat dissipation port 103 penetrating the heat dissipation portion 102 compared with the heat dissipation portion 102 in the embodiment 1, and the extension direction of the heat dissipation port 103 is parallel to the extension direction of the vehicle body length, and the threading hole 104 is provided on the mounting plate 1, and the threading hole 104 is located in the extension direction of the heat dissipation port 103, and the lampshade 201 is provided with two openings 2011. When the lampshade 201 is mounted on the mounting plate 1 When the vehicle is in motion, the two openings 2011 overlap with the two ends of the heat dissipation port 103 respectively, so that both ends of the heat dissipation port 103 can be exposed and connected to the outside world; when the vehicle body is in motion, air flow can flow in through an opening 2011 on the lampshade 201, and after passing through one end of the heat dissipation port 103, it flows out from the other end of the heat dissipation port 103, and finally flows out from another opening 2011 on the lampshade 201, so that the heat generated by the lamp beads on the light source board 202 during operation can be partially taken away by the air flow.

[0031] The threading hole 104 is located in the extension direction of the heat dissipation port 103, so that the airflow flowing through the heat dissipation port 103 can also flow through the power cord of the lamp light source circuit board 202. This makes it possible for the connection between the power cord and the lamp light source circuit board 202 to dissipate heat while the lamp light source circuit board 202 is dissipating heat.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
