Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive taillight technology, and in particular relates to an automotive reversing light module. Background Technology
[0002] Automotive taillights are lighting devices installed at the rear of a vehicle for illumination, warning, and signal transmission, playing a crucial role in driving safety. With the development of the automotive industry and technological advancements, taillights not only emphasize functionality but also focus on design and visibility.
[0003] In a car reversing light module, the reversing light is white and illuminates when the vehicle is in reverse gear, lighting up the road behind the vehicle and indicating to the surroundings that the vehicle is reversing or about to reverse. Based on optical principles, most existing reversing lights use white lenses as light source filters. However, car taillight modules integrate many light modules, such as brake lights, which use red lenses. The combination of white and red lenses affects the overall aesthetics of the car taillight module, making it impossible to improve the aesthetic design of the car taillight module through an integrated lens color design. Utility Model Content
[0004] This utility model provides a car reversing light module, which is implemented as follows: A car reversing light module includes:
[0005] A lamp holder, the interior of which is hollow to form a light chamber, and a mask assembly for filtering light is provided at the port where the light chamber communicates with the outside.
[0006] The light-emitting module includes a lamp holder assembled on the side of the light chamber away from the mask assembly, a transparent thick-walled component disposed inside the light chamber, and a green LED module. The light beam generated by the green LED module passes through the transparent thick-walled component and the pink transparent mask provided on the mask assembly in sequence, and then forms white light that diffuses outward.
[0007] Preferably, the mask assembly further includes a red opaque mask and a red transparent mask. The red opaque mask has a slot at its center for receiving a pink transparent mask. The red opaque mask is snapped onto the lamp holder, while the red transparent mask wraps around the outer edge of the red opaque mask.
[0008] Preferably, the lamp holder is fixed on the lamp frame, the green LED module is disposed on the end face of the lamp holder facing the transparent thick-walled part, and the light beam generated by the green LED module is directed toward the mask assembly.
[0009] Preferably, the interior of the light chamber is provided with a decorative element, and the center of the decorative element is provided with a fixing groove for a transparent thick-walled element to pass through, and the transparent thick-walled element is connected to the inner wall of the lamp holder through the decorative element.
[0010] Preferably, the end face of the transparent thick-walled component facing the green LED module is the light-incident surface of the focusing unit, and the end face of the transparent thick-walled component facing the mask assembly is the light-exiting surface of the focusing unit. The light beam generated by the green LED module enters from the light-incident surface of the focusing unit and exits from the light-exiting surface of the focusing unit.
[0011] Preferably, the light-concentrating unit has an inwardly recessed light-concentrating area on its light-incident surface, and the light beam generated by the green LED module enters the light-concentrating area and diffuses to the transparent thick-walled component through the light-concentrating area.
[0012] Compared with the prior art, the embodiments of this application have the following main advantages:
[0013] The automotive reversing light module provided by this utility model features a thick-walled grating unit on the light-incident surface of a transparent thick-walled component. After passing through the transparent thick-walled component, the collimated LED light undergoes total internal reflection and is directed towards the light-out direction of the thick-walled component, preventing light pattern deviation. The light beam emitted from the light-out surface of the focusing unit forms white light after passing through a pink transparent cover. Here, the transparent thick-walled component performs total internal reflection on the collimated LED light to obtain a bright and uniform light beam. The filtering effect of the pink transparent cover further enhances the brightness and uniformity of the white light, thus warning following vehicles. The entire reversing light module is covered with a pink cover similar in color to the brake lights, eliminating the need for a separate white cover to allow white light to pass through. This reduces the use of white covers, ensuring color consistency in the automotive taillight module and improving the overall aesthetics of the taillights. Attached Figure Description

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] This utility model embodiment provides an automotive reversing light module, such as... Figure 1 As shown, the automotive reversing light module includes:
[0022] The lamp holder 30 has a hollow interior forming a light chamber 301. A mask assembly for filtering light is provided at the port of the light chamber 301 that communicates with the outside. The mask assembly 10 includes a pink transparent mask 11, a red opaque mask 12, and a red transparent mask 13. The red opaque mask 12 is nested outside the pink transparent mask 11, while the red transparent mask 13 is nested on the outer edge of the red opaque mask 12 away from the end face of the light chamber 301.
[0023] The light-emitting module 20 includes a lamp holder 21 assembled on the side of the light chamber 301 away from the mask assembly, a transparent thick-walled component 23 disposed inside the light chamber 301, and a green LED module 22. The light beam generated by the green LED module 22 passes through the transparent thick-walled component 23 and the pink transparent mask 11 provided on the mask assembly in sequence and then forms white light that diffuses outward.
[0024] In this embodiment, the green LED module 22 has a power of 1W. The green LED module 22 used in this application is the LUXEON Versat 3030 ST PC Green product from LUMILEDS. This provides a unique spectrum and achieves white reverse illumination through a red cover glass. The corresponding circuit design and power supply still employ existing technologies. The green beam generated by the green LED module 22 passes through the transparent thick-walled component 23 and then through the pink transparent cover 11 before diffusing outwards as white light. The pink transparent cover 11 is integrated with other parts of the car taillight for seamless matching. This allows the entire reversing light to be fitted with a pink cover similar in color to the brake light, eliminating the need for a separate white cover to allow white light to pass through, thus improving the overall aesthetics of the car taillight. It should be noted that while this application uses a pink cover design, in practical applications, a pink cover can provide a brighter beam. To improve overall color coordination, the brake light cover can also be a red cover with a similar color spectrum.
[0025] The green beam of light passes through the transparent thick-walled component 23 mainly to totally reflect the collimated light of the LED onto the light-emitting direction of the thick-walled component, thus avoiding deviation of the light pattern. Here, the end face of the transparent thick-walled component 23 facing the green LED module 22 is the light-incident surface of the focusing unit, and the end face of the transparent thick-walled component 23 facing the mask assembly is the light-emitting surface of the focusing unit. The light-incident surface of the focusing unit is provided with a thick-walled grating unit, and the beam of light emitted from the light-emitting surface of the focusing unit forms white light after passing through the pink transparent mask 11. The transparent thick-walled component 23 performs total internal reflection of the collimated light of the LED to obtain a bright and uniform beam of light, and then uses the filtering effect of the pink transparent mask 11 to obtain a bright and uniform white light to warn the following vehicles.
[0026] In a preferred embodiment of this invention, the interior of the light chamber 301 is provided with a decorative element 40, and the center of the decorative element 40 is provided with a fixing groove for a transparent thick-walled element 23 to pass through. The transparent thick-walled element 23 is connected to the inner wall of the lamp holder 30 through the decorative element 40.
[0027] In this embodiment, the decorative element 40 serves as the mounting base for the transparent thick-walled element 23, mainly helping to fix the transparent thick-walled element 23.
[0028] In a preferred embodiment of this invention, the light-concentrating unit has an inwardly recessed light-concentrating region 201 on its light-incident surface. The light-concentrating region 201 is a slot structure formed by an arc-shaped bottom edge protruding towards one side of the green LED module 22 and two sets of parallel side structures. The green LED module 22 is aligned with the light-concentrating region 201, and most of the light beam generated by the green LED module 22 enters the light-concentrating region 201 and diffuses to the transparent thick-walled component 23 through the light-concentrating region 201.
[0029] In this embodiment, the transparent thick-walled component 23 has a thick-walled grating unit on its light-facing surface facing the green LED module 22.
[0030] It should be noted that, for the sake of simplicity, the foregoing embodiments are all described as a series of actions. However, those skilled in the art should understand that the present invention is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to the present invention.
