Description

A multi-angle automotive signal light LED light guide device Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a multi-angle automotive signal light LED light guide device. Background Technology

[0002] In the field of automotive lighting, light-emitting diodes (LEDs) are commonly used as light sources and are placed in various automotive lights, including taillights and signal lights. When using these light sources, they are usually matched with a headlight guide, which directs the light emitted by the light source from the light source to the location where light needs to be emitted.

[0003] Some automotive light guides are typically long and narrow, with LEDs positioned at one end or on one side of the light guide. Currently, most of these types emit light in one direction only, failing to accommodate multiple directions. When multi-angle light emission is required, additional light guides are needed, leading to increased costs and requiring optimization. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a multi-angle automotive signal light LED light guide device to overcome the shortcomings of existing devices.

[0005] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a multi-angle automotive signal light LED light guide device, including a light guide body and a decorative frame covering the outside of the light guide body, the decorative frame being disposed on the back of the light guide body, and an oblique reflective surface being provided below the light guide body;

[0006] The top of the light guide body is provided with a first incident surface, and the back of the light guide body is provided with a second incident surface. Light guide grooves are opened on the first incident surface and the second incident surface. Several light guide teeth are provided in the light guide grooves. Each light guide tooth is stepped and evenly arranged along the length of the light guide body.

[0007] A further improvement is that: the decorative frame is provided with an illumination element, which is detachably connected to the decorative frame; the left and right ends of the light guide body are provided with positioning parts, and the light guide body is detachably connected to the decorative frame through the positioning parts.

[0008] A further improvement is that the tooth-like structure of the optical guide tooth is either triangular or trapezoidal.

[0009] A further improvement is that the lighting component includes a lamp panel and a slot opened on the outside of the decorative frame. The lamp panel is slidably connected to the slot, and a number of LED beads are provided on the side of the lamp panel facing the light guide body. The LED beads are fixedly connected to the lamp panel.

[0010] A further improvement is that the left and right ends of the lamp panel are provided with connecting ears, and fixing bolts are fitted on the connecting ears. The fixing bolts pass through the connecting ears and are threadedly connected to the bolt holes opened on the outside of the decorative frame.

[0011] A further improvement is that the positioning part includes a positioning block and a plug-in block. The plug-in block is fixedly installed at the left and right ends of the light guide body, and the positioning block is fixedly installed at the left and right ends of the inner sidewall of the decorative frame.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] As shown in Figures 1, 2, 3, 4, 5, and 6, this embodiment proposes a multi-angle automotive signal light LED light guide device, including a light guide body 1 and a decorative frame 3 covering the outside of the light guide body 1. The decorative frame 3 is set on the back of the light guide body 1, and an oblique reflective surface 2 is provided below the light guide body 1.

[0025] The top of the light guide body 1 is provided with a first incident surface 11, and the back of the light guide body 1 is provided with a second incident surface 12. A light guide groove 101 is opened on the first incident surface 11 and the second incident surface 12. A plurality of light guide teeth 102 are provided in the light guide groove 101. Each light guide tooth 102 is stepped and evenly arranged along the length of the light guide body 1.

[0026] As shown in Figure 2, light enters the light guide body 1 through the first incident surface 11 and the second incident surface 12. Besides emitting light along the X-axis, the light also emits light along a non-X-axis direction due to the action of the light guide teeth 102 within the first incident surface 11. After hitting the oblique reflecting surface 2, the light is reflected and emitted along the X-axis, thus illuminating multiple areas. Achieving multi-angle light emission through a single light guide effectively reduces costs.

[0027] The decorative frame 3 is equipped with an illumination element, which is detachably connected to the decorative frame 3. The left and right ends of the light guide body 1 are provided with positioning parts, and the light guide body 1 is detachably connected to the decorative frame 3 through the positioning parts.

[0028] The detachable connection method makes it easy for staff to assemble the lighting components, the decorative frame 3 and the light guide body 1, and facilitates subsequent maintenance.

[0029] It is worth explaining in detail that the tooth structure of the optical guide tooth 102 is either triangular or trapezoidal.

[0030] When light propagates inside the light guide material, the light is reflected and refracted multiple times by the tooth-like structure of the light guide teeth 102, which is usually trapezoidal, triangular or other regular geometric shapes. This breaks the straight propagation path of the light and makes it evenly distributed on the surface of the light guide strip, avoiding uneven light spots.

[0031] Specifically, the lighting component includes a lamp plate 4 and a slot on the outside of the decorative frame 3. The lamp plate 4 is slidably connected to the slot. Several LED beads 43 are provided on the side of the lamp plate 4 facing the light guide body 1, and the LED beads 43 are fixedly connected to the lamp plate 4. The lamp plate 4 is installed on the outside of the decorative frame 3 by plugging and unplugging. After the lamp plate 4 is powered on, the LED beads 43 at the bottom of the lamp plate 4 will be lit up, emitting light towards the light guide body 1.

[0032] More specifically, the left and right ends of the lamp panel 4 are provided with connecting ears 42, and fixing bolts 41 are fitted on the connecting ears 42. The fixing bolts 41 pass through the connecting ears 42 and are threadedly connected to the bolt holes opened on the outside of the decorative frame 3. The lamp panel 4 is fixed to the outside of the decorative frame 3 by bolt connection. When the lamp panel 4 is removed from the outside of the decorative frame 3 for replacement, the fixing bolts 41 are rotated to unscrew them from the bolt holes on the outside of the decorative frame 3.

[0033] Regarding the Positioning Department:

[0034] The positioning part includes a positioning block 32 and a plug-in block 13. The plug-in block 13 is fixedly disposed at the left and right ends of the light guide body 1, and the positioning block 32 is fixedly disposed at the left and right ends of the inner side wall of the decorative frame 3. The positioning block 32 has a positioning groove 31 on the side facing the light guide body 1. The plug-in block 13 is slidably connected to the positioning groove 31. The left and right ends of the decorative frame 3 are provided with fastening mechanisms to prevent the plug-in block 13 from falling out of the positioning groove 31.

[0035] After adjusting the position of the light guide body 1, ensure that the oblique reflective surface 2 is located below the light guide body 1 and the first incident surface 11 is located at the top of the light guide body 1. After pushing the light guide body 1 into the decorative frame 3, the plug-in blocks 13 at both ends of the light guide body 1 will also be pushed into the decorative frame 3. The plug-in blocks 13 will be inserted into the positioning grooves 31 opened on the side wall of the positioning block 32. The positioning grooves 31, through cooperation with the plug-in blocks 13, limit the light guide body 1 from both ends, so that the light guide body 1 will not deflect during installation and use, ensuring stable light output.

[0036] More specifically, the fastening mechanism includes a positioning bolt 5, which is threadedly connected to the connecting holes at both ends of the decorative frame 3. The connecting holes are coaxial with the positioning hole 14 in the center of the plug-in block 13. The positioning bolt 5 passes through the connecting hole and is threadedly connected to the positioning hole 14. After the plug-in block 13 is fully pushed into the positioning groove 31, the positioning bolt 5 on the outside of the decorative frame 3 is rotated, and the positioning bolt 5 is screwed from the connecting hole into the positioning hole 14. The positioning bolt 5 will perform a secondary limiting on the plug-in block 13 by cooperating with the positioning hole 14, so that the plug-in block 13 will not slip out of the positioning groove 31 and the light guide body 1 will not slip out of the decorative frame 3.

[0037] How this application works:

[0038] Light enters the light guide body 1 through the first incident surface 11 and the second incident surface 12. Besides emitting light along the X-axis, the light also emits light along a non-X-axis direction due to the action of the light guide teeth 102 within the first incident surface 11. After hitting the oblique reflecting surface 2, the light is reflected and emitted along the X-axis, illuminating multiple areas. Achieving multi-angle light emission through a single light guide effectively reduces costs. The lighting component and the decorative frame 3 are detachably connected, and the light guide body 1 is detachably connected to the decorative frame 3 via a positioning part. This detachable connection facilitates assembly of the lighting component, decorative frame 3, and light guide body 1 by workers, and facilitates subsequent maintenance.
