1. A method for producing a holding device (1), wherein a light guide channel (2) is formed in the holding device (1) and extends from a first end section (2a) to a second end section (2b) of the holding device (1), wherein the first end section (2a) has a receiving region, in which a first optical element (3) can be fastened in a form-fitting manner, wherein the second end section (2b) has a stop surface (5) for the connection to a second optical element (4), and wherein the method comprises the following steps:

a) providing the first optical element (3),

b) providing an injection molding device for carrying out an injection molding process, wherein the injection molding device has two mold halves,

c) introducing the first optical element (3) into the first mold half of the injection molding device,

d) closing the mold halves,

e) forming the first end section (2a) of the holding device,

f) forming a shell of the holding device (1), which encloses the light guide channel (2),

g) forming the second end section (2b), which terminates the shell of the holding device (1), together with the stop surface (5).

The present invention relates to the technical field of vehicle illumination and, in particular, relates to a vehicle lamp optical element assembly, a vehicle lamp comprising the vehicle lamp optical element assembly, and an automobile comprising the vehicle lamp. The vehicle lamp optical element assembly comprises a primary optical element assembly and a secondary optical element assembly, wherein the primary optical element assembly comprises a primary optical element and a first support for supporting the primary optical element, and the secondary optical element assembly comprises a secondary optical element and a second support for supporting the secondary optical element, wherein the first support and the second support are connected in a matching manner so as to enable the primary optical element and the secondary optical element to be relatively fixed. The primary optical element and the secondary optical element are assembled into an integral structure, such that relative positions of the primary optical element and the secondary optical element are directly determined, and direct positioning between the primary optical element and the secondary optical element is realized. The positioning precision and the mounting reliability of the primary optical element and the secondary optical element can be ensured, such that the accuracy and functional stability of a light shape of the vehicle lamp are ensured.
