Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a vehicle light emitting module and a vehicle using the same. Background Art

[0002] In the prior art, the ISD (Intelligent Signal Display) intelligent interactive function is usually achieved by directly irradiating an LED light source matrix or by cooperating with multi-particle thick-walled units, or by using a relatively high-cost OLED surface light source panel. Different graphics are spliced ​​through the combination of different units to convey different texts or information. In order to achieve a clear graphic illustration, it is necessary to minimize the problems of light leakage and light crosstalk between the matrix units. Low-cost lamp structure design often uses decorative ring spacing and other means to block light, but light crosstalk is often unavoidable, and the decorative ring partition forms a visual interval, weakening the integration effect. There are problems with the selection of the partition frame black bars and display discontinuity. OLED has a good display effect but the overall cost of the panel is relatively high, and OLED technology has high requirements for the vehicle lighting environment, which is not conducive to product promotion.

[0003] Therefore, in order to solve the problems existing in the above-mentioned technologies, it is necessary to further optimize and improve the structure of the light-emitting module used in automobiles in order to reduce the problems of light leakage and light crosstalk between the matrix units.

[0027] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0028] Embodiment 1:

[0029] See also Figures 1 to 3 As shown, this embodiment provides a vehicle light-emitting module, including: a light source assembly and a light guide assembly used together. The light source assembly includes a plurality of light sources 1, each of which can be independently controlled to light up, so by adjusting the on and off, brightness and color of each light source 1, the vehicle light-emitting module of this embodiment can present a variety of optical effects.

[0030] The light guide assembly includes a plurality of light guide columns 2 arranged in an array, where each light guide column 2 may correspond to more than one light source 1. The drawings of this embodiment only take the case where one light guide column 2 corresponds to one light source 1 as an example.

[0031] On the basis of the above structure, it should be noted that in the embodiment, every two adjacent light guide columns 2 are seamlessly connected. As for the arrangement rules according to which multiple light guide columns 2 are assembled to form a light guide assembly, it can be arranged in combination with the actual application scenario, and this embodiment does not make an absolute limitation on this. The reason why the adjacent light guide columns 2 are seamlessly connected here, that is, there is no gap between the adjacent light guide columns 2, is mainly to make the light guide columns 2 have almost no boundary partition after matching the corresponding light source 1, and the overall appearance is unified.

[0032] It is to be further explained that, firstly, the light incident surface 2a of each light guide column 2 can be a plane or a curved surface. Secondly, the light emitting surface 2c of each light guide column 2 can be a plane or a curved surface.

[0033] It is also necessary to explain that the light incident surface 2a and the light emitting surface 2c of each light guide column 2 are both regular polygons, which means that each light guide column 2 is a prism structure. Light emitting surfaces 2c of different shapes can output light with different optical effects. For example, in conjunction with the attached drawings, the light incident surface 2a and the light emitting surface 2c of each light guide column 2 are both regular hexagons.

[0034] In addition, regarding the light guide assembly of this embodiment, it is necessary to further explain:

[0035] In the first implementation, the light emitting surfaces 2c of the multiple light guide pillars 2 included in the light guide assembly are in the same plane. At this time, the light incident surfaces 2a of the multiple light guide pillars 2 may be in the same plane or not, and this embodiment does not make an absolute limitation on this. In a preferred case, the light incident surfaces 2a of the multiple light guide pillars 2 are also in the same plane, which means that the lengths of the multiple light guide pillars 2 are exactly the same.

[0036] In the second implementation, the light guide assembly includes multiple light guide columns 2 of different lengths; the light incident surfaces 2a of the multiple light guide columns 2 are in the same plane, and the light emitting surfaces 2c of the multiple light guide columns 2 are in a high and low distribution structure, thereby forming a three-dimensional light emitting effect under the light guide assembly.

[0037] In addition, it should be noted that the light incident surface 2a and the light exit surface of each light guide column 2 can be both smooth surfaces or rough surfaces, and this embodiment does not make an absolute limitation on this.

[0038] Furthermore, in an optional implementation, the light-emitting surface 2 c of each light-guiding column 2 is provided with leather grain or pattern, so that the dispersion of the output light is better.

[0039] In addition, a reflective coating structure 2b is provided on the outer wall surface of the light guide component. The design of the reflective coating structure 2b can reduce or leak light from the light guide column 2, avoid the leakage of unnecessary stray light, and greatly improve the imaging quality of the vehicle light-emitting module.

[0040] Finally, it is necessary to explain that the vehicle light-emitting module also includes an annular light shielding plate 3 arranged on the circumferential side of the light-emitting surface 2c of the light guide component. The annular light shielding plate 3 here can be combined with the light guide component to form different modeling schemes, and on the other hand, the annular light shielding plate 3 can be made of high-strength and lightweight materials, such as hard plastic materials or aluminum materials, so as to ensure the support strength of the annular light shielding plate 3 and reduce the overall weight of the vehicle light-emitting module.
