Technical Field

[0001] This application relates to the field of automotive lighting, and more specifically, to an edge-illuminated vehicle logo light. Background Technology

[0002] A car logo light is a light fixture used to display the vehicle's brand logo. Most existing car logo lights use LEDs to emit light through a lens containing the car logo to illuminate it. However, existing car logo lights require a significant amount of space, making it difficult to achieve a slim and lightweight design. Furthermore, since they emit light directly from the car logo itself, they cannot provide uniform illumination to highlight the logo's shape.

[0003] Therefore, a lightweight, reliable car logo light that can emit light evenly on the car logo is needed to meet the usage requirements. Utility Model Content

[0004] The purpose of this application is to provide an edge-illuminated car logo light that enables the car logo to be illuminated by a uniform and soft light so that it can be observed by the human eye, thereby improving the optical performance and visual appeal of the car logo light.

[0005] This application is implemented as follows:

[0006] This application provides an edge-illuminating vehicle logo light, comprising:

[0007] The lamp holder is made of a light-transmitting material and has an adhesive layer on one side for connecting to the vehicle body.

[0008] The substrate is made of a light-transmitting material and is attached to the side of the lamp holder away from the backing layer. At least one LED is provided on the substrate.

[0009] The outer lamp cover is connected to the lamp holder on the side away from the adhesive layer. The outer lamp cover and the lamp holder form a cavity that covers the LED lamp. The side of the outer lamp cover away from the lamp holder has a car logo. The surfaces of the outer lamp cover near and away from the lamp holder are respectively coated with a reflective paint layer for reflecting light and an opaque electroplated metal layer.

[0010] In some alternative implementations, the cavity is filled with a translucent sealant layer.

[0011] In some alternative embodiments, a light guide seat is also included, which is sleeved on the outside of the lamp holder and detachably connected to the vehicle body. The outer periphery of the light guide seat protrudes to form a light guide wall sleeved on the outside of the outer lamp cover. The light guide seat and the light guide wall are provided with a first reflective layer on the side facing the outer lamp cover.

[0012] In some alternative implementations, the light guide wall is threadedly connected to a light-transmitting cover, the light guide cover having an opening in the middle for the outer lampshade to pass through.

[0013] In some alternative implementations, the outer periphery of the outer lampshade is recessed to form a positioning groove for engaging with the bottom wall of the opening.

[0014] In some alternative embodiments, the surface of the lamp holder facing the outer lampshade is recessed to form a receiving groove for accommodating the substrate.

[0015] In some alternative implementations, a second reflective layer is provided on one side surface of the lamp holder connecting to the adhesive backing layer.

[0016] In some alternative implementations, the substrate is a flexible circuit board.

[0017] The beneficial effects of this application are as follows: The edge-illuminating car logo light provided by this application includes a lamp holder made of light-transmitting material, a substrate made of light-transmitting material, and an outer lamp cover. One side of the lamp holder is connected to an adhesive layer for connecting to the vehicle body. The substrate and the outer lamp cover are connected to the side of the lamp holder away from the adhesive layer. At least one LED light is provided on the substrate.

[0029] The features and performance of the edge-illuminated vehicle logo light of this application will be further described in detail below with reference to embodiments.

[0030] Example 1

[0031] like Figure 1 As shown, this application embodiment provides an edge-illuminated vehicle logo light, which includes a light-transmitting lamp holder 100, a light-transmitting substrate 120, and an outer lamp cover 140. One side of the lamp holder 100 is connected to an adhesive layer 110 for connecting to a vehicle body 300; the other side of the lamp holder 100 is provided with a receiving groove 180. The substrate 120 is a flexible circuit board and is fixedly disposed within the receiving groove 180. LED lights 130 are spaced apart on the substrate 120. The outer lamp cover 140 is connected to the lamp holder 100 and is provided with the receiving groove 180. On one side of 80, the outer lamp cover 140 and the lamp holder 100 form a receiving cavity 150 that covers the LED lamp 130. The receiving cavity 150 is filled with a light-transmitting sealant layer 160. The side of the outer lamp cover 140 facing the lamp holder 100 is coated with a reflective paint layer for reflecting light. The surface of the outer lamp cover 140 away from the lamp holder 100 is provided with a car logo and coated with an opaque electroplated metal layer. The surface of the lamp holder 100 connected to the adhesive backing layer 110 is provided with a second reflective layer 190. In this embodiment, the lamp holder 100 is made of plexiglass, and the reflective paint layer is a white paint layer.

[0032] The edge-emitting car logo light provided in this application embodiment has a light-transmitting substrate 120 disposed between a light-transmitting lamp holder 100 and an outer lamp cover 140. The lamp holder 100 is connected to the vehicle body 300 through an adhesive layer 110. The inner and outer walls of the outer lamp cover 140 are coated with a reflective paint layer for reflecting light and an opaque electroplated metal layer, respectively. When the LED light 130 on the substrate 120 emits light, it shines on the reflective paint layer on the inner wall of the outer lamp cover 140 and is reflected. The reflected light passes through the light-transmitting substrate 120 and the light-transmitting lamp holder 100 and shines on the surface of the vehicle body 300 and is reflected and emitted from the edge of the outer lamp cover 140. This makes the car logo on the outer wall of the outer lamp cover 140 visible to the human eye in a more uniform and softer state.

[0033] Traditional car logo lights have shortcomings in terms of light propagation and presentation. This is because the light propagation path design of traditional car logo lights is not reasonable enough. The light is emitted from the light source and directly projected onto the surface of the car logo on the outer lamp cover. This simple propagation method easily leads to uneven light distribution on the surface of the car logo, which cannot fully display the visual effect that the car logo should have.

[0034] The edge-emitting car logo light provided in this embodiment uses a reflective paint layer on the inner wall of the outer lamp cover 140 to uniformly reflect the light emitted by the LED lamp 130, changing the direction of light propagation. This changes the light from a single direct path to a multi-angle light distribution after reflection. The reflected light passes through the light-transmitting substrate 120. The flexible circuit board substrate 120 not only allows the light to pass through smoothly but also minimizes light loss, maximizing the intensity and uniformity of the light. Finally, the light passing through the substrate 120 passes through the lamp holder 100 made of plexiglass, where the lamp holder 100 performs secondary diffusion of the light, resulting in a more uniform and softer light that is reflected by the vehicle body and observed by the human eye. This greatly improves the light propagation path and distribution effect, allowing the car logo to present a clearer, more uniform, and uniquely visually appealing pattern when illuminated, effectively enhancing the optical performance and visual appeal of the car logo light.

[0035] On the other side of the lamp holder 100, there is a receiving groove 180 for accommodating the substrate 120, which ensures that the substrate 120 is stably fixed in the receiving groove 180. The outer lamp cover 140 and the lamp holder 100 form a receiving cavity 150 covering the LED lamp 130. The receiving cavity 150 is filled with a light-transmitting sealant layer 160. On the one hand, the sealant layer 160 can improve the sealing of the connection between the outer lamp cover 140 and the lamp holder 100, preventing external rainwater and dust from entering the receiving cavity 150. On the other hand, the sealant layer 160 can also be used to evenly diffuse the light emitted by the LED lamp 130, forming a more uniform light-emitting area. A second reflective layer 190 is provided on the side surface of the lamp holder 100 that connects to the backing layer 110, which can reflect the light passing through the lamp holder 100, ensuring that the light is stably emitted through the edge of the outer lamp cover 140 and received by the human eye.

[0036] Example 2

[0037] like Figure 2 As shown, this application embodiment provides an edge-illuminating vehicle logo light, which has a structure largely the same as the edge-illuminating vehicle logo light provided in Embodiment 1. The difference is that in this embodiment, it further includes a light guide seat 200 sleeved on the outside of the lamp holder 100 and connected to the vehicle body through an adhesive layer 250. The outer periphery of the light guide seat 200 protrudes to form a light guide wall 210 sleeved on the outside of the outer lamp cover 140. The light guide seat 200 and the light guide wall 210 are provided with a first reflective layer 240 on the side facing the outer lamp cover 140. The light guide wall 210 is connected to a light-transmitting light guide cover 220 by threads. The center of the light guide cover 220 is provided with an opening 230 for the outer lamp cover 140 to pass through. The outer periphery of the outer lamp cover 140 is recessed to form a positioning groove 170 for engaging the bottom wall of the opening 230. The adhesive layer 250 is formed of adhesive.

[0038] The edge-illuminating car logo light provided in this application embodiment has a light guide seat 200 connected to the vehicle body on the outside of the lamp holder 100. The outer periphery of the light guide seat 200 protrudes to form a light guide wall 210 sleeved on the outside of the outer lamp cover 140. The light guide seat 200 and the light guide wall 210 are provided with a first reflective layer 240 on the side facing the outer lamp cover 140. The first reflective layer 240 provided on the side facing the outer lamp cover 140 of the light guide seat 200 and the light guide wall 210 can further reflect the light that shines on the surface of the vehicle body 300 after passing through the lamp holder 100, so that the light stably shines out from the gap between the outer lamp cover 140 and the light guide wall 210, thereby stably forming a uniform light emission at the edge of the outer lamp cover 140 and being received by the human eye, so that the car logo on the outer wall of the outer lamp cover 140 presents a uniform light emission.

[0039] The light guide wall 210 is connected to a light guide cover 220 via threads. The light guide cover 220 has an opening 230 in the middle for the outer lamp cover 140 to pass through. The light guide cover 220 can be used to evenly diffuse the light emitted from the gap between the outer lamp cover 140 and the light guide wall 210, improve the uniformity of the light, and prevent external mud and rainwater from entering the gap between the outer lamp cover 140 and the light guide wall 210 and affecting the light emission effect. The outer periphery of the outer lamp cover 140 is recessed to form a positioning groove 170 for engaging the bottom wall of the opening 230. The positioning groove 170 can be used to support and position the light guide cover 220, ensuring that the light guide cover 220 stably closes the gap between the outer lamp cover 140 and the light guide wall 210.

[0040] The embodiments described above are some, but not all, of the embodiments of this application. The detailed description of the embodiments of this application is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
