DETAILED DESCRIPTION

(72) Solutions in embodiments of the present disclosure will be further described below in detail in conjunction with the drawings.

(73) In the description of this application, it is to be noted that, in the case of no explanation to the contrary, the orientation or position relationship indicated by the orientation words such as “up”, “down”, “left”, “right”, “front” and “rear” are based on the orientation or position relationship indicated by the direction of a vehicle in a normal driving state after a lighting module and a vehicle lamp of this application are installed on the vehicle, and are merely for facilitating the description of this application and simplifying the description, rather than indicating or implying that the pointed apparatus or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation of this application. In addition, terms such as “first” and “second” are used merely for the purpose of description and are not to be construed as indicating or implying relative importance. For example, terms “first position” and “second position” are two different positions.

(74) In the description of this application, it is to be noted that terms “mounted”, “joined” and “connected” are to be understood in a broad sense unless otherwise expressly specified and limited. For example, the term “connected” may refer to “securely connected” or “detachably connected”, may refer to “mechanically connected” or “electrically connected” or may refer to “connected directly”, “connected indirectly through an intermediary” or “connected in two components”. For those of ordinary skill in the art, the preceding terms in this application can be construed depending on specific contexts.

(75) This application provides a lighting module. The lighting module includes a plurality of high-beam light sources 33, a plurality of low-beam light sources 43, a high-beam optical element 32 and a low-beam optical element 42. The high-beam optical element 32 includes a plurality of high-beam light guide bodies, and the plurality of high-beam light guide bodies are in one-to-one correspondence with the plurality of high-beam light sources 33. Rear ends of the plurality of high-beam light guide bodies are separated from one another, and front ends of the plurality of high-beam light guide bodies are sequentially connected to form a continuous high-beam light emitting surface 323. The low-beam optical element 42 includes at least one low-beam light guide body. The plurality of low-beam light sources 43 are disposed at a rear end of the at least one low-beam light guide body, and a front end of the at least one low-beam light guide body forms a continuous low-beam light emitting surface 423. The low-beam optical element 42 and the high-beam optical element 32 are disposed one above the other. An upper boundary of the high-beam light emitting surface 323 is attached to a lower boundary of the low-beam light emitting surface 423; alternatively, a spacing distance between the upper boundary of the high-beam light emitting surface 323 and the lower boundary of the low-beam light emitting surface 423 in an up-and-down direction is less than or equal to 2 mm.

(76) A shape of the lower boundary of the low-beam light emitting surface 423 adapts to a shape of a low-beam cut-off line, and a shape of the upper boundary of the high-beam light emitting surface 323 adapts to a shape of a high-beam cut-off line. It is to be noted that the low-beam cut-off line and the high-beam cut-off line are both cut-off lines defined in the relevant laws and regulations of vehicle lamps and are terms well known to those skilled in the art. The shape of the cut-off line can be configured according to the required boundary shape of the light shape.

(77) Compared with a primary optical element adopting a reflector in the related art, the lighting module provided in this application has a smaller volume and a more compact structure to satisfy the requirements of a user. The high-beam optical element 32 adopts the plurality of high-beam light guide bodies to achieve an anti-glare high beam function. The low-beam optical element 42 may be provided with one or more low-beam light guide bodies according to the actual requirements of the lighting module, in a case where one low-beam light guide body is adopted, the structure is stable and simple so that the ordinary low-beam function can be achieved; and in a case where the plurality of low-beam light guide bodies are adopted, some auxiliary functions of the low beam can be achieved. In this application, the low-beam optical element 42 and the high-beam optical element 32 are adopted, which greatly increases the light utilization rates of the low-beam light sources 43 and the high-beam light sources 33; the upper boundary of the high-beam light emitting surface 323 is attached to the lower boundary of the low-beam light emitting surface 423 or a very small space exists between the upper boundary of the high-beam light emitting surface 323 and the lower boundary of the low-beam light emitting surface 423, so that a good connection between the low-beam light shape and the high-beam light shape can be ensured and the phenomenon of dark areas or uneven light shape transitions can be avoided.

(78) In a specific embodiment of this application, as shown in FIGS. 1 to 15, the lighting module further includes a supporting member 6, which is provided with a groove 61.

A front end of the groove 61 is provided with second positioning protrusions 63 capable of contacting a lower surface of each of the high-beam light guide bodies. As shown in FIG. 11, a lower surface of the pressing plate 7 is provided with third positioning protrusions 71 capable of contacting an upper surface of each of the high-beam light guide bodies.

(89) In this embodiment, the number of the low-beam light incident parts 421 is thirteen, and the number of the low-beam light passing part 422 is one. The thirteen low-beam light incident parts 421 are disposed in two rows in an up-and-down direction and at a rear end of the low-beam light passing part 422. Two low-beam light incident parts 421 are located in the middle of the upper row, and the other eleven low-beam light incident parts 421 are located in the lower row. In this manner, the lighting intensity of the middle position of the low-beam light shape can be generally greater than the lighting intensity of the side position of the low-beam light shape. In this embodiment, the number of the low-beam light sources 43 is the same as the number of the low-beam light incident parts 421, and each of the low-beam light incident parts 421 is disposed opposite to one of the low-beam light sources 43.

In an embodiment, the first fastener 53 is a screw, a threaded bolt or other fasteners capable of fastening, and can be selected according to the actual requirements.
