Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, specifically a fully light-guiding, uniform, waterproof brake light. Background Technology

[0002] A high-mounted brake light disclosed in authorization announcement number CN216833429U includes a lamp housing, an illumination component disposed inside the lamp housing, a mounting plate mounted on the lamp housing, a light-emitting opening on the mounting plate, a light-transmitting plate disposed at the light-emitting opening, and a plurality of fastening components disposed at the end of the mounting plate away from the light-transmitting plate, each of the plurality of fastening components being connected to a bolt, the bolt passing through the light-transmitting plate and the mounting plate and being connected to the fastening components.

[0003] When installing the brake light, first insert the bolts into the holes in the light-transmitting plate, and then insert all the bolts into the fastening assembly. After the bolts are inserted into the fastening assembly, you can directly pull the fastening assembly towards the mounting plate by pulling the bolts. This will bring each fastening assembly into contact with the mounting plate, thus initially fixing each fastening assembly to the mounting plate. The entire brake light will be temporarily fixed, so the operator no longer needs to hold the light body and can tighten the bolts with one hand, making the operation more convenient.

[0004] The technical solution in the prior art document eliminates the need to hold the lamp body and allows for one-handed screw tightening, making operation more convenient. However, the patent uses multiple independent LEDs as the light source, which easily leads to the formation of obvious dot-like light spots, uneven light emission, and poor visual effect. Furthermore, when the light passes through the lampshade, it is easy to generate stray light or dark areas, affecting the warning effect. At the same time, the lamp's sealing is insufficient, allowing moisture and dust to easily enter, leading to short circuits in the internal circuits, contamination of optical components, or condensation, affecting the lamp's lifespan and performance. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fully light-guiding, uniform, and waterproof brake light, which solves the problems of uneven light emission from dotted light spots, optical dark areas or stray light easily generated in the lamp cover, and insufficient sealing that makes it susceptible to moisture and dust intrusion, affecting its lifespan.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully light-guiding, uniform, waterproof brake light, comprising a housing assembly, an optical assembly, a circuit assembly, and a sealing assembly; The housing assembly includes a lamp housing, a light-transmitting mask, a light source substrate, and an LED light source. The lamp housing and the light-transmitting mask are fastened together to form a sealed cavity. The optical components are disposed within the sealed cavity and include a light guide, a reflective layer, a light source substrate, and an LED light source. The light guide is a transparent body with one light-incident surface and the remaining surfaces being light-outcrystal surfaces, and its interior or surface is provided with light-guiding microstructures. The reflective layer is attached to at least one surface of the light guide, excluding the light-outcrystal and light-incident surfaces. The light source substrate and the LED light source constitute a light source module and are disposed opposite to each other on the light-incident surfaces of the light guide. The circuit assembly is used to power the light source module and control its illumination. The sealing assembly includes a mask sealing ring disposed at the junction of the lamp housing and the light-transmitting mask.

[0007] In one specific embodiment, the light-emitting surface of the light guide is a continuous curved surface.

[0008] In one specific embodiment, the light guide microstructure is a reflective dot array printed or engraved on the back of the light guide, with the dot size gradually increasing from near the LED light source to away from it.

[0009] In one specific embodiment, the light source module includes a plurality of LED light sources arranged linearly along the light incident surface of the light guide.

[0010] In one specific embodiment, the inner side of the light-transmitting mask is provided with a locking block that engages with the opening of the lamp housing.

[0011] In one specific embodiment, a mounting bracket for securing the entire brake light to the vehicle body is also included.

[0012] Compared with the prior art, this utility model provides a fully light-guiding, uniform, waterproof brake light, which has the following beneficial effects: In the technical solution disclosed in this utility model, the card block is used to facilitate the assembly of the outer shell component and the lamp housing, and the sealing component is used to increase the sealing after assembly, thereby achieving excellent waterproof performance and a compact and reliable structure. The optical component is used to achieve large-area uniform light emission.

[0013] The optical components designed in this invention conduct and scatter the light emitted by the LED light source within the light guide body, and finally emit it uniformly from the light-emitting surface of the entire continuous curved surface. This eliminates the dot-shaped light spots and dark areas of traditional brake lights, achieving a striking, high-quality, uniform surface light emission effect and providing a better warning effect.

[0016] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] Figures 1-4 As one embodiment of the present invention, a fully light-guiding, uniform, waterproof brake light includes a housing assembly 1, an optical assembly 2, a circuit assembly 3, and a sealing assembly 4.

[0018] The specific problems addressed in this embodiment are: uneven light emission due to dotted light spots, the easy generation of optical dark areas or stray light in the lamp cover, and insufficient sealing that makes it susceptible to moisture and dust intrusion, affecting its lifespan. This utility model utilizes the locking block 13 to facilitate the assembly of the outer shell component 1 and the lamp housing 11, and utilizes the sealing component 4 to increase the sealing performance after assembly, thereby achieving excellent waterproof performance and a compact and reliable structure. The optical component 2 enables large-area uniform light emission.

[0019] Optical component 2 is disposed in a sealed cavity and includes lamp housing 11, light-transmitting mask 12, light source substrate 24 and LED light source 25. Optical component 2 is disposed in a sealed cavity and includes light guide 21, reflective layer 22, light source substrate 24 and LED light source 25. Light guide 21 is a transparent body with one side as light-incident surface and the other side as light-exit surface. Light guide microstructure 23 is provided inside or on the surface of light guide 21. Reflective layer 22 is attached to at least one surface of light guide 21 other than light-exit surface and light-incident surface. Light source substrate 24 and LED light source 25 constitute a light source module and are disposed opposite to each other on the light-incident surface of light guide 21. Circuit component 3 is used to power the light source module and control its lighting. Sealing component 4 includes mask sealing ring disposed at the junction of lamp housing 11 and light-transmitting mask 12. In this specific embodiment, the light-exit surface of light guide 21 is a continuous curved surface adapted to the contour of the rear of the car. The optical component 2 of this invention conducts and scatters the light emitted by the LED light source 25 within the light guide 21, and finally emits it uniformly from the light-emitting surface of the entire continuous curved surface. This eliminates the dotted light spots and dark areas of traditional brake lights, achieving a striking, high-quality uniform surface light emission effect and providing a better warning effect.

[0020] In this specific embodiment, the light guide microstructure 23 is a reflective dot array printed or engraved on the back of the light guide 21, with the dot size gradually increasing from near the LED light source 25 to far away; this gradient distribution of dots can precisely control the emission ratio of light, compensate for the light intensity attenuation caused by distance, thereby ensuring that the brightness of the entire light-emitting surface is highly consistent and there is no unevenness in brightness.

[0021] In this specific embodiment, the light source module includes multiple LED light sources 25, which are arranged linearly along the light incident surface of the light guide 21. The multiple LEDs, as linear light sources, provide the light guide 21 with abundant and evenly distributed initial light energy, which is the basis for achieving large-area uniform brightness.

[0022] In this specific embodiment, a locking block 13 is provided on the inner side of the light-transmitting mask 12, which engages with the opening of the lamp housing 11; the locking block 13 facilitates the quick assembly and positioning of the lamp housing 11 and the light-transmitting mask 12.

[0023] In this specific embodiment, a mounting bracket 5 for fixing the entire brake light to the vehicle body is also included; the mounting bracket 5 provides a standardized vehicle mounting interface, which enables the brake light assembly to be conveniently and securely integrated into the rear of various vehicle models.

[0024] Working principle: When the driver presses the brake, an electrical signal is transmitted to the control drive board of circuit component 3 through the electrical interface, driving the LED light source 25 to light up. Light enters from the light-incident surface of the light guide 21, and is transmitted forward through total internal reflection inside the light guide 21. Along the way, it is scattered by the gradient-distributed light-guiding microstructures 23 on the back, deviating from the total internal reflection angle, and then uniformly exits from the light-emitting surface. Simultaneously, the reflective layer 22 reflects the downwardly scattered light back into the light guide 21 for utilization, improving light efficiency. Finally, uniform red light passes through the light-transmitting mask 12 to form a conspicuous, particle-free brake warning signal.

[0025] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
