Description

Technical Field

[0001] This utility model relates to the technical field of charging pile lighting devices, and in particular to a U-shaped light for charging piles. Background Technology

[0002] Charging stations are crucial equipment for providing electric vehicles with electrical energy, and are typically deployed in public charging stations, underground parking lots, and other similar locations. To effectively guide user operation, charging stations are generally equipped with status indicator lights. However, current status indicator lights on charging stations suffer from several technical shortcomings that urgently need to be addressed:

[0003] 1. Insufficient light uniformity, especially in non-linear configurations: Existing solutions commonly exhibit uneven light distribution when applied to curved or U-shaped areas (e.g., the central area is too bright while the two ends are too dark). This is primarily because the light guide plate design is often based on a straight line, and the layout of its internal light guiding structure (such as dots / microstructures) is not optimized for curved paths, resulting in localized bright spots or dark areas. In complex curved surfaces or U-shaped structures, achieving high light uniformity is difficult, significantly impacting visual indication and user experience.

[0004] 2. Low light energy utilization and light leakage: Existing LED strip components typically use side-emitting or excessively wide-angle LED light sources, rather than a light emission method perpendicular to the incident surface of the light guide plate. This design results in a large amount of luminous flux failing to couple effectively into the light guide plate, increasing scattering losses during the coupling process. Simultaneously, a significant amount of light leaks into non-target directions (such as the internal cavity of a charging pile), not only wasting energy but also potentially causing internal light pollution or interference, and weakening the visibility of target indication signals in the external environment. Therefore, existing designs suffer from low light energy utilization and poor energy conversion efficiency, making it difficult to meet the requirements of green and energy-saving lighting.

[0005] 3. Poor adaptability to irregular structures: Standardized straight LED strips are primarily designed for linear layouts. When applied to U-shaped indicator areas of charging stations, they are prone to light breaks or edge light attenuation at corners or junctions. While flexible LED strips can be used for physical adaptation, this typically leads to further deterioration of light uniformity. Current technologies lack high-performance integrated lighting solutions that can be seamlessly integrated into non-standard geometries (such as U-shapes), significantly limiting their deployment in emerging application scenarios such as charging stations.

[0006] Therefore, how to provide a U-shaped light for charging piles that improves light uniformity and luminous efficiency has become a technical problem that urgently needs to be solved. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a U-shaped light for charging piles to improve light uniformity and light efficiency.

[0008] This utility model is implemented as follows: A U-shaped light for charging piles, comprising:

[0009] A faceplate with a U-shaped light-transmitting area at the bottom of the front;

[0010] A light guide component is disposed at the bottom of the face cover and is detachably connected to the face cover, with the light emission direction facing the U-shaped light-transmitting area;

[0011] The light guide component includes:

[0012] A light guide plate has several light guide holes evenly distributed to uniformly guide light, and the light output direction of each light guide hole is towards the U-shaped light transmission area;

[0013] A light strip assembly is disposed on the light guide plate, with the light emission direction perpendicular to the light guide hole;

[0014] A layer of reflective paper is applied to the LED strip assembly.

[0015] Furthermore, it also includes:

[0016] A power module is connected to the light strip assembly.

[0017] Furthermore, the light guide plate has a U-shaped structure.

[0018] Furthermore, the light strip assembly has a U-shaped structure.

[0019] Furthermore, the light guide plate is provided with a U-shaped groove for accommodating the light strip assembly.

[0020] Furthermore, the light guide hole is vertically disposed on the side of the light guide plate and communicates with the U-shaped groove.

[0021] The advantages of this utility model are:

[0022] By setting up a face cover and a light guide assembly, the face cover has a U-shaped light-transmitting area, and the light guide assembly includes a light guide plate, a light strip assembly, and reflective paper. The U-shaped light guide plate has evenly distributed light guide holes, and the U-shaped light strip assembly emits light vertically toward the light guide holes of the light guide plate. The reflective paper covers the light strip assembly, which improves the coupling efficiency of light entering the light guide plate in a vertical incident manner. The light guide holes optimize the uniformity of light distribution in the U-shaped path, and the reflective paper restricts light leakage. Thus, while natively adapting to the U-shaped structure of the charging pile, it achieves high uniformity lighting and high luminous efficiency output, ultimately greatly improving light uniformity and luminous efficiency.

[0030] This utility model embodiment provides a U-shaped light 100 for charging piles, which solves the technical problems of insufficient light uniformity, low light energy utilization and light leakage, and poor adaptability of irregular structure in the status indicator lights of charging piles in the prior art, and achieves the technical effect of greatly improving light uniformity and light efficiency.

[0031] The technical solution in this utility model embodiment is to solve the above problems. The overall idea is as follows: the light strip assembly 22 emits light through the light guide hole of the light guide plate 21 in a vertical incident manner, which improves the coupling efficiency of the light entering the light guide plate 21. The light guide hole optimizes the uniformity of the light distribution in the U-shaped path, and the reflective paper 23 restricts light leakage. Thus, while being natively adapted to the U-shaped structure of the charging pile, it achieves high uniformity lighting and high light efficiency output.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] Please refer to Figures 1 to 4 As shown, a preferred embodiment of the U-shaped light 100 for a charging pile according to this utility model includes:

[0034] A face cover 1 has a U-shaped light-transmitting area 11 on the lower part of the front; the face cover 1 is used to provide protection for the charging pile (not shown); the U-shaped light-transmitting area 11 is used for the light guide component 2 to emit light outward;

[0035] A light guide component 2 is disposed at the bottom of the face cover 1 and is detachably connected to the face cover 1, with the light emission direction facing the U-shaped light-transmitting area 11; the light guide component 2 is used to emit light for illumination or status indication.

[0036] The light guide component 2 includes:

[0037] A light guide plate 21 has several light guide holes (not shown) evenly distributed for uniform light distribution, and the light output direction of each light guide hole is towards the U-shaped light transmission area 11.

[0038] A light strip assembly 22 is disposed on the light guide plate 21, with the light emission direction perpendicular to the light guide hole;

[0039] A layer of reflective paper 23 is placed on the light strip assembly 22 to prevent light from spreading in unwanted directions and to ensure that most of the light shines in the desired direction.

[0040] Also includes:

[0041] A power module (not shown) is connected to the light strip assembly 22 and is used to supply power to the light strip assembly 22.

[0042] The light guide plate 21 has a U-shaped structure.

[0043] The light strip assembly 22 has a U-shaped structure.

[0044] The light guide plate 21 is provided with a U-shaped groove 211 for accommodating the light strip assembly 22.

[0045] The light guide hole is vertically disposed on the side of the light guide plate 21 and communicates with the U-shaped groove 211.

[0046] Working principle of this utility model:

[0047] The power module supplies power to the light strip assembly 22. After the light strip assembly 22 is powered on, it emits light vertically into the light guide hole of the light guide plate 21 and relies on the reflective paper 23 to constrain the light leakage. The light passing through the light guide hole shines outward through the U-shaped light-transmitting area 11 of the cover 1.

[0048] In summary, the advantages of this utility model are as follows:

[0049] By setting up a face cover and a light guide assembly, the face cover has a U-shaped light-transmitting area, and the light guide assembly includes a light guide plate, a light strip assembly, and reflective paper. The U-shaped light guide plate has evenly distributed light guide holes, and the U-shaped light strip assembly emits light vertically toward the light guide holes of the light guide plate. The reflective paper covers the light strip assembly, which improves the coupling efficiency of light entering the light guide plate in a vertical incident manner. The light guide holes optimize the uniformity of light distribution in the U-shaped path, and the reflective paper restricts light leakage. Thus, while natively adapting to the U-shaped structure of the charging pile, it achieves high uniformity lighting and high luminous efficiency output, ultimately greatly improving light uniformity and luminous efficiency.
