Embodiment Construction

[0055] In the following description, the same components and features are denoted by the same reference numerals, respectively.

[0056] with the help of Figures 1 to 3 The construction of the light module 10 according to the invention is described. image 3 The light module 10 is shown in a perspective view in the final installed state.

[0057] like figure 1 and 2 As shown, the light module 10 basically has four functional main components, which are each formed as a preassembled composite structural unit: a light source unit 12 , a primary optical unit 14 , a supporting frame 16 and a secondary optical unit 18 . in press figure 1 and 2 In the view of , these structural units are shown in sequence along the installation direction 20 . In order to achieve the final assembly of the light module 10 , the preassembled structural units 12 , 14 , 16 , 18 are displaced relative to each other substantially along the assembly direction 20 and joined together.

Abstract

The module has a light source unit (12), a primary optic unit (14) and a secondary optic unit (18) formed as pre-mounted components and joined for final assembly of the module. The secondary optic unit includes a lens device (48) e.g. collecting lens, for projecting light distribution into radiation light distribution of the module. Bolt-like fastening sections (56) and cylinder openings (58) position-precisely fasten the primary optic and source units at each other. An opening (60) and a pin-like projection position-precisely fasten the secondary optic unit relative to the primary optic unit.

Description

technical field [0001] The invention relates to a light module which can be used in particular in motor vehicle headlights. Background technique [0002] In the present application, a light module refers to the headlight's own light-emitting unit which emits the desired irradiated light distribution. Depending on the field of application, this irradiated light distribution should have a specific, usually legally prescribed, individual luminance profile. [0003] On the one hand, it should provide a blackout light distribution, such as dipped beam or fog lights. The shaded light distribution is characterized by a light-dark boundary extending essentially horizontally in sections. In this case, the section of the light-dark boundary facing the oncoming traffic flow preferably extends straight and lower than the section of the light-dark boundary facing away from the oncoming traffic flow. An obliquely rising section of the light-dark boundary (the so-called "zigzag" light d...
