[0031] The body of a car is usually equipped with a car logo to display the manufacturer's information. Since the car logo itself is also a means of publicity for the manufacturer, it is usually set in a more conspicuous place on the car, such as the front hood and front face of the car, and the trunk lid at the rear of the car. In order to make the car logo more integrated into the overall appearance design of the car, the car logo is generally designed with a metallic luster. The production principle of this type of car logo is to obtain a plastic matrix through injection molding technology, and then perform metal color electroplating on the matrix, so as to obtain a car logo with a metallic texture without using metal parts to reduce production costs.

[0032] At present, in order to make the car logo highly recognizable at night or in other dimly lit scenes, some car logos have also introduced a luminous function. Specifically, a lamp is installed inside the car logo, the car logo body is a transparent part and the metallic paint layer is also a light-transmitting paint layer. When the light is not turned on, the surface of the car logo is metallic and is no different from the traditional car logo; when the light is turned on, the light emitted by the lamp can pass through the car logo body and the metallic paint layer, so that the car logo pattern can glow, and the car logo can be clearly identified at night or in other dimly lit scenes.

[0033] However, due to the need to set up internal lighting, the entire set of components of the car logo undoubtedly takes up more space than traditional car logos, and due to the increase in parts, assembly also takes more time. In addition, in actual use, it is found that the light of the current luminous car logo is not uniform enough. After turning on the light, the dot matrix light source inside the car logo can be clearly seen, which affects the appearance of the car logo.

[0034] In this regard, the present application proposes a car luminous LOGO lamp, which makes the structure more compact by installing both the light module 200 and the inner light distribution mirror 300 in the base 100, saving the space occupied by the lamp, and can guide the light module 200 to be installed in place through the guide column 120 on the base 100, thereby improving the assembly efficiency. In addition, by setting the inner light distribution mirror 300, the light emitted by the light module 200 is softened, making the light emission effect of the lamp more uniform and having a better lighting effect.

[0035] Reference Figure 1 The automotive LOGO light fixture in the embodiment of the present application includes a base 100, a light module 200, an inner light mirror 300, a fixing screw 400 and an outer light mirror 500. The base 100 is the main structure of the automotive LOGO light fixture, the light module 200, the inner light mirror 300 and the fixing screw 400 are all arranged inside the base 100, and the outer light mirror 500 can protect the internal components and prevent dust after being combined with the base 100. At the same time, the surface of the outer light mirror 500 is also provided with a LOGO pattern to be displayed, and the outer light mirror 500 faces the outside of the car when installed.

[0036] Specifically, refer to Figure 2 The base 100 is in a shell shape, including a bottom plate and side plates arranged around the edge of the bottom plate, and the side plates extend along the x direction. The specific shape of the base 100 is adjusted based on the LOGO pattern. In this embodiment, an elliptical LOGO pattern is taken as an example, so correspondingly, the base 100 is elliptical. An accommodating space is provided inside the base 100, and the lighting module 200, the internal light distribution mirror 300 and the fixing screw 400 are all installed in the accommodating space. A threaded hole 110 and a guide column 120 extending along the x direction are provided inside the base 100.

[0037] Reference Figure 3 The lighting module 200 includes a substrate 210 and lamp beads 220. In order to make the light emitted by the lighting module 200 as uniform as possible, the number of lamp beads 220 is multiple, and the lamp beads 220 are installed on the substrate 210 in an array. The lamp beads 220 are all LED lamp beads. The substrate 210 is provided with a first mounting hole 211 and a guide hole 212, and the guide column 120 can pass through the guide hole 212. Therefore, when the lighting module 200 is installed in the base 100, the guide column 120 passes through the guide hole 212, which plays a role in guiding the assembly worker to install the substrate 210 to a predetermined position.

[0038] The inner light distribution mirror 300 is a transparent part and has an atomized layer on its surface, so that when light passes through the inner light distribution mirror 300, the atomized layer can reduce the sharpness of the light and soften the light. Furthermore, the inner light distribution mirror 300 is in an arc shape, and the concave surface of the inner light distribution mirror 300 faces the light module 200. The concave shape of the inner light distribution mirror 300 is used to diffuse the light emitted by the light module 200, thereby expanding the light outward, avoiding the light being concentrated in the middle of the outer light distribution mirror 500 and making the LOGO pattern light uneven. A second mounting hole 310 is provided on the inner light distribution mirror 300, which is used to allow the fixing screw 400 to pass through and fix the inner light distribution mirror 300 in the base 100.

[0039] The fixing screw 400 is used to fix the light module 200 and the inner light mirror 300. After passing through the second mounting hole 310 of the inner light mirror 300 and the first mounting hole 211 of the base 210, it is threadedly connected with the threaded hole 110 of the base 100. When tightening the fixing screw 400, it simultaneously drives the light module 200 and the inner light mirror 300 to press against the base 100, thereby fixing the two.

[0040] The exterior light mirror 500 is connected to the base 100 and closes the accommodation space, which plays a role in protecting the internal components. In addition, the surface of the exterior light mirror 500 is provided with a relevant LOGO pattern, which is outlined by a combination of two or more paint layers. The outermost paint layer is a metal paint layer formed by PVD coating, which has a metallic luster and is also a light-transmitting paint layer. Light can be emitted outward through the metal paint layer to achieve a luminous effect of the car logo. The specific paint layer and spraying process of the exterior light mirror 500 are existing technologies and will not be repeated here.

[0041] The specific connection method between the exterior light distribution mirror 500 and the base 100 may be a snap connection, a bolt connection, a bonding connection, etc. In this embodiment, the exterior light distribution mirror 500 and the base 100 are connected by bonding, and the combination of the two is achieved by ultrasonic welding.

[0042] Furthermore, a mounting post 130 extending along the x direction is provided in the base 100, and the threaded hole 110 is provided on the mounting post 130. When the lighting module 200 is installed, since the mounting post 130 extends outward relative to the bottom plate of the base 100, the lighting module 200 and the mounting post 130 are abutted against each other and fixed by the fixing screws 400, a gap is left between the lighting module 200 and the bottom plate of the base 100. The gap is used to allow air to circulate, thereby promoting heat dissipation of the lighting module 200.

[0043] In order to support the light module 200 more stably, the inner wall of the base 100 is provided with an abutment block 140, and the abutment block 140 is provided with a stepped plane, which can abut against the base plate 210 of the light module 200. Therefore, after the light module 200 is installed in place, the abutment block 140 can abut against the light module 200 together with the installation column 130, limit the installation position of the light module 200 along the x direction, and prevent the light module 200 from being installed too deep and reducing its heat dissipation space.

[0044] Furthermore, the length of the mounting post 130 is shorter than that of the guide post 120, so that when the light module 200 is installed, the guide post 120 can contact the light module 200 before the mounting post 130, thereby guiding the assembly. In addition, a plurality of ribs 131 are provided on the side of the mounting post 130 to enhance the connection strength between the mounting post 130 and the base 100, and also to weaken the stress concentration effect at the connection between the mounting post 130 and the base 100.

[0045] Furthermore, the end of the guide post 120 is conical or terraced, so that the size of the end of the guide post 120 is smaller, and when the lighting module 200 is installed, the guide post 120 is easier to enter the first installation hole 211 of the substrate 210. The outer diameter of the guide post 120 gradually increases from the end along the x direction. During the installation of the substrate 210 along the x direction, the first installation hole 211 will be in contact with the outer surface of the guide post 120, thereby inhibiting the lateral movement of the substrate 210.

[0046] It is worth noting that in order to prevent the guide column 120 from having difficulty passing through the first mounting hole 211 due to production errors, the diameter of the first mounting hole 211 is larger than the outer diameter of the guide column 120 and the first mounting hole 211 is in the shape of a slot.

[0047] Furthermore, a plurality of reinforcing ribs 121 extending along the x-direction are provided on the side of the guide column 120 to enhance the connection strength between the guide column 120 and the base 100 and also to weaken the stress concentration effect at the connection between the guide column 120 and the base 100 .

[0048] Furthermore, a limit block is provided in the base 100, and a corresponding limit groove 213 is provided in the base 210 of the lighting module 200. The limit block and the limit groove 213 are nested and connected to limit the movement of the base 210, and also limit the rotation of the base 210 in the base 100.

[0049] The above is a specific description of the preferred implementation methods of the present application, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present application, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present application.
