Description

Technical Field

[0001] This application relates to the technical field of vehicle body trim components, specifically to a front marker light for automobiles. Background Technology

[0002] To address the problem of traditional car logos being difficult to identify at night, various luminous car front logo lights have emerged in the prior art. For example, Chinese utility model patent with authorization announcement number CN214028493U discloses a car front logo light. The device includes a luminous front logo plate, a base plate, a light circuit board, and a logo integrated with the luminous front logo plate. The light circuit board (20) is mounted in reverse on the base plate. The overall structure is simplified by eliminating the light shield. At the same time, an aluminum film is plated on the inner surface of the luminous front logo plate and the logo. The reflection and shielding effect of the aluminum film stabilizes the light source, so that the light emitted by the LED beads only shines through the light-transmitting part of the outer contour of the logo and the inner circle of the front logo plate, achieving the contour lighting effect.

[0003] This technology relies on an aluminum coating process to control light. Both the illuminated logo signboard and the inner surface of the logo need to be coated with an aluminum film to stabilize the light source and prevent light diffusion. However, the coating waste and chemical additives generated during the aluminum coating process can easily burden the environment and pose significant environmental risks. At the same time, the uniformity of the aluminum film coating directly determines the light control effect. If the coating thickness is uneven, the edges are not smooth, or wear and tear occurs after long-term use, it can easily cause problems such as light leakage and light diffusion, resulting in blurred light emission boundaries and affecting the clarity of nighttime recognition.

[0017] Reference Figures 1 to 4This application proposes an embodiment of an automotive front marker light, which includes: a base shell 10, a circuit board 20, a light-diffusing plate 30, a light-transmitting lamp cover 40, and a light-shielding decorative plate 50. The circuit board 20 has a plurality of LED light-emitting elements 60 on its upper end. The light-diffusing plate 30 is disposed above the circuit board 20. The light-transmitting lamp cover 40 is mounted on the upper end of the base shell 10 and sealed to it. The light-transmitting lamp cover 40 has a first recessed structure 41 recessed towards the circuit board 20. The shape of the light-shielding decorative plate 50 matches the shape of the first recessed structure 41. The first recessed structure 41 has a first mounting structure 90 inside it. The light-shielding decorative plate 50 has a second mounting structure 70. The light-shielding decorative plate 50 is mounted on the light-transmitting lamp cover 40 and blocks the first recessed structure 41 through the cooperation of the second mounting structure 70 and the first mounting structure 90.

[0018] The LED light-emitting elements on the circuit board 20 emit light upwards; the light-diffusing plate 30 is located between the circuit board 20 and the light-transmitting lampshade 40, and undertakes the function of light homogenization and guidance; the light-transmitting lampshade 40 achieves the dual functions of protection and light transmission by sealing assembly with the bottom shell 10, and its first recessed structure 41 provides an installation reference for the light-shielding decorative plate 50; the light-shielding decorative plate 50 is firmly fixed on the light-transmitting lampshade 40 by its own second mounting structure 70 precisely matching the first mounting structure 90 of the first recessed structure 41, and by physically blocking the first recessed structure 41, the light emitted by the LED light-emitting elements can only pass through the unblocked area of ​​the light-transmitting lampshade 40, thereby achieving the light-emitting effect of a specific pattern.

[0019] There is no need for aluminum plating film to control light. Physical shielding replaces chemical plating, avoiding environmental pollution from waste and chemical auxiliaries during the aluminum plating process and improving environmental performance. In addition, the light-transmitting lampshade 40 is sealed to the bottom shell 10, and the decorative light-shielding plate is directly installed on the outside of the light-transmitting lampshade 40 without affecting the seal between the light-transmitting lampshade 40 and the bottom shell 10.

[0020] Specifically, the first mounting structure 90 is a first snap-fit ​​structure disposed on the inner wall of the first recessed structure 41, and the second mounting structure 70 is a second snap-fit ​​structure disposed on the side of the light-shielding decorative plate 50 near the light-transmitting lampshade 40, wherein the light-shielding decorative plate 50 is snapped onto the light-transmitting lampshade 40.

[0021] The first mounting structure 90 is a first snap-fit ​​structure, such as a slot or protrusion, on the inner wall of the first recessed structure 41 of the light-transmitting lampshade 40. The second mounting structure 70 is a second snap-fit ​​structure, such as a matching protrusion or slot, on the side of the light-shielding decorative plate 50 near the light-transmitting lampshade 40. During assembly, by aligning the second snap-fit ​​structure of the light-shielding decorative plate 50 with the first snap-fit ​​structure of the first recessed structure 41 and applying axial force, the two are elastically engaged, achieving rapid fixation of the light-shielding decorative plate 50 and the light-transmitting lampshade 40, while ensuring the accuracy of the blocking position and avoiding light leakage caused by assembly deviation. No complex processes such as welding or bolt fixing are required, making assembly convenient.

[0022] Preferably, the plurality of LED light-emitting elements 60 are located on the circuit board 20 and distributed in an area that avoids the light-shielding decorative plate 50. The plurality of LED light-emitting elements are evenly distributed on the circuit board 20, and the arrangement area is deliberately arranged to avoid the projection area of ​​the light-shielding decorative plate 50 on the circuit board 20; when the LED light-emitting elements are working, most of the light is directly shone onto the light-diffusing plate 30 and then emitted, avoiding the light being directly blocked by the light-shielding decorative plate 50 and causing light loss.

[0023] In this embodiment, the light-diffusing plate 30 is provided with a second recessed structure 31 that avoids the first recessed structure 41. The second recessed structure 31 on the light-diffusing plate 30 is precisely matched with the shape of the first recessed structure 41 of the light-transmitting lamp cover 40 and the light-shielding decorative plate 50, so as to achieve structural avoidance and prevent interference between the light-diffusing plate 30 and the light-transmitting lamp cover 40 and the light-shielding decorative plate 50, which helps to reduce the thickness of the front marker light of the car.

[0024] In this embodiment, the light-diffusing plate 30 is provided with a first reflective layer at the lower end of the second recessed structure 31, the circuit board 20 is provided with a second reflective layer at the upper end, and the inner wall of the bottom shell 10 is provided with a third reflective layer.

[0025] In the light emitted by the LED light source, the light that hits the lower end of the second recess of the light-diffusing plate 30 is reflected by the first reflective layer to the second reflective layer; the light that hits the second reflective layer is reflected to the light-diffusing plate 30, and the light that diverges toward the inner wall of the bottom shell 10 is reflected to the light-diffusing plate 30 by the third reflective layer. Through the synergistic effect of multiple reflective layers, all the scattered light that might have escaped is guided to the light-emitting area of ​​the light-diffusing plate 30, thereby maximizing the utilization of light.

[0026] Preferably, the light-diffusing plate 30 is provided with a lens structure 80 on the periphery of the second recessed structure 31. The lens structure 80 is used to refract the light that is irradiated to the side of the second recessed structure 31 toward the light-emitting area of ​​the light-diffusing plate 30.

[0027] This claim provides a lens structure 80 on the periphery of the second recessed structure 31 of the light-diffusing plate 30. The lens structure 80 is designed for scattered light rays that are irradiated to the side of the second recessed structure 31: the light rays emitted by the LED light-emitting element that irradiate the side wall of the second recessed structure 31 will hit the lens structure 80. The lens structure 80 changes the light path through its own optical curved surface, refracting the light rays that originally escaped to the side to the light-emitting area of ​​the light-diffusing plate 30, ensuring that the light is concentrated in the light-emitting area of ​​the light-transmitting plate, forming a preset light-emitting pattern.

[0028] Specifically, the lens structure 80 includes a plurality of annular prisms, each prism being arranged in a ring around the side wall of the second recessed structure 31. The plurality of prisms are arranged sequentially from bottom to top along the side of the second recessed structure, and the bottom surface of the prisms faces the light-emitting area.

[0029] The ring-shaped prism can be integrally injection molded with the light-diffusing plate 30. The lower prism refracts the low-angle light emitted by the LED, while the upper prism refracts the high-angle light. Through the synergistic effect of multiple ring-shaped prisms, all scattered light at different heights and angles is accurately refracted to the light-emitting area of ​​the light-diffusing plate 30.

[0030] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
