[0041] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0042] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "setting", and "connection" should be understood in a broad sense. For example, the term "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] like Figure 1 As shown, the signal light of the basic embodiment of the present invention includes a light-emitting module 2 and a light guide 1. The light-emitting module 2 includes a plurality of light-emitting units 23. The plurality of light-emitting units 23 can emit different signal lights to produce different signal prompt functions. The light guide 1 is set on the emission path of the light emitted by the light-emitting unit 23. Corresponding to each light-emitting unit 23, a plurality of light-incoming ends are provided on the light guide 1. The light-incoming ends can be set in the form of a concentrator and / or a reflector. The light-incoming end in the form of a concentrator is formed as a concentrating portion 11, and the light-incoming end in the form of a reflector is formed as a reflecting portion 12. The concentrating portion 11 and the reflecting portion 12 correspond to one or more light-emitting units 23 on the light guide 1. Therefore, when the light-emitting unit 23 emits light, the emitted light passes through the concentrating portion 11 and / or the reflecting portion 12 and enters the light guide 1. The light guide 1 couples the incident light to form a uniform light-emitting area. Furthermore, while meeting the requirements of lamp shape and luminous effect, the light guide 1 is set to a thick-walled light guide 1. For the assembly process of the overall structure of the signal lamp, the use of a thick-walled light guide 1 can reduce the number of parts, optimize the production process, and reduce the cost of the lamp. In addition, since a thick-walled light guide 1 is used and the light-emitting module is set in the thick-walled light guide 1, the most compact space structure adopted can realize multiple signal functions.

[0044] Specifically, the light-emitting module 2 at least includes a first light-emitting module 21 and a second light-emitting module 22, wherein the first light-emitting module 21 and the second light-emitting module 22 are both provided with a plurality of light-emitting units 23, and the plurality of light-emitting units 23 are arranged corresponding to the light-entering surfaces of the light-collecting portion 11 and the reflecting portion 12, and the light-guiding body 1 can separate the plurality of light-emitting modules 2, so as to limit the light emitted by the plurality of light-emitting modules 2 from interfering with each other through the light-guiding body 1. The light emitted by the plurality of light-emitting units 23 in the plurality of light-emitting modules 2 can be received by the light-collecting portion 11 and the reflecting portion 12, and the light is then transmitted into the light-guiding body 1 after being received by the light-collecting portion 11 and / or the reflecting portion 12, and the light is coupled in the light-guiding body 1, and the light after coupling can form a uniform light-emitting effect, thereby realizing the combination of multifunctional signals that can be realized by the light emitted by the plurality of light-emitting units 23, and the plurality of light-emitting units 23 include at least three or more, thus solving the problem that the three light-emitting units 23 in the prior art cannot be combined to form a combination requirement of a plurality of light-color functional signal lights.

[0045] More specifically, the plurality of light-emitting units 23 include a first light-emitting unit 231, a second light-emitting unit 232, and a third light-emitting unit 233, wherein the first light-emitting unit 231 constitutes the first light-emitting module 21, and the first light-emitting unit 231 is correspondingly arranged at the light incident end of the light-collecting portion 11, so that the light emitted from the first light-emitting unit 231 can be injected into the light-collecting portion 11, and after the light-collecting effect of the light-collecting portion 11, it is injected into the main structure of the light guide body 1, and the second light-emitting unit 232 and the third light-emitting unit 233 together constitute the second light-emitting module 22, and the second light-emitting unit 232 and the third light-emitting unit 233 are correspondingly arranged at the light incident end of the reflective portion 12, and after the light enters the reflective portion 12, After being reflected by the reflective surface inside the reflective part 12, the reflected light is also emitted into the main structure of the light guide 1, and then the light emitted by the first light-emitting unit 231, the second light-emitting unit 232 and the third light-emitting unit 233 are coupled in the main structure of the light guide 1 and then emitted. Here, the third light-emitting unit 233 is the signal function emitted by the ADS lamp, and the first light-emitting unit 231 and the second light-emitting unit 232 are the signal functions emitted by other functional signal lamps of the vehicle. The first light-emitting unit 231 and the second light-emitting unit 232 can be one of the signal lamps such as fluorescent lamps, position lamps, turn signals, etc., and each functional signal lamp can be connected by an optical guide to enable it to have a turn flow function. Therefore, the above-mentioned setting method is adopted to enable the ADS lamp to couple the functional signal light emitted by other functional signal lamps, and the light after coupling can meet the requirements of luminous uniformity.

[0046] In addition, the first light-emitting module 21 formed by the first light-emitting unit 231 and the second light-emitting module 22 formed by the second light-emitting unit 232 and the third light-emitting unit 233 are independent of each other. Therefore, the first light-emitting module 21 or the second light-emitting module 22 can be controlled to light up separately, and the second light-emitting module 22 is composed of the second light-emitting unit 232 and the third light-emitting unit 233, but the second light-emitting unit 232 or the third light-emitting unit 233 can also be controlled to light up separately, and the second light-emitting unit 232 and the third light-emitting unit 233 set on the same light-emitting module can also be controlled to light up synchronously, so as to realize personalized control of the light-emitting module 2. Of course, the first light-emitting module 21 can also be provided with multiple light-emitting units 23, and the second light-emitting module 22 can also be provided with a single light-emitting unit 23. The number and function of the light-emitting units 23 in the first light-emitting module 21 and the second light-emitting module 22 can be determined according to the actual needs of the user.

[0047] like Figure 1As shown, the light guide 1 extends toward both sides of the light emitting module 2. The extended light guide 1 can be linear, L-shaped, U-shaped, etc. The light guide 1 of different shapes can be flexibly adjusted according to the customer's design requirements, and the extended light guide 1 can completely cover the size range of the light emitting module 2, that is, the light emitted by the light emitting module 2 can be completely received by the light guide 1 and evenly emitted through the exit surface 13 of the light guide 1 to form a uniform lighting effect.

[0048] Furthermore, the light rays converged by the focusing part 11 and the light rays reflected by the reflecting part 12 are completely received by the light guide part and then coupled, and then the coupled light rays are uniformly emitted through the same emission surface 13, thereby obtaining a uniform lighting effect. That is, the light rays incident into the focusing part 11 are aggregated by the focusing part 11 and then emitted through the second emission surface 132, and the light rays incident into the reflecting part 12 are also reflected to the first emission surface 131 and emitted, and the first emission surface 131 and the second emission surface 132 together constitute the emission surface 13, that is, the focusing part 11 and the reflecting part 12 share the same emission surface 13. The light surfaces aggregated and reflected by the focusing part 11 and the reflecting part 12 will couple a variety of light rays through the light guide 1, so the light rays emitted by a variety of different light-emitting units 23 can be combined to obtain coupled light rays, and the coupled light rays can realize a combination of a variety of different signal functions. In addition, part of the focusing portion 11 protrudes out of the light guide 1, and the end of the protruding portion is recessed into the light guide 1 to form a focusing surface, and a focusing pattern is provided on the focusing surface. An arc-shaped reflecting surface is provided on the reflecting portion 12, and a reflecting pattern is provided on the arc-shaped reflecting surface. Through the arrangement of the focusing pattern and the reflecting pattern, the light emitted by the multiple light-emitting units 23 can be converged and reflected into the light guide 1, thereby completing the coupling of the light.

[0049] The vehicle of the present invention adopts the signal lamp of the present invention, and therefore also has the above advantages.
