Embodiment Construction

[0023] In the following embodiments, the same reference numerals denote the same features unless otherwise stated.

[0024] figure 1 A front view of a first embodiment of a lighting module 1 according to the invention is shown. where it can be identified that the Figure 6 The light-emitting module 1 of the vehicle headlight 2 shown in , wherein the light-emitting module 1 has at least one light-emitting element 3 that can be excited by irradiation with laser light to radiate visible light. The light-emitting element 3 is arranged on the light-transmissible carrier element 4 in the figure 2 At the rear side shown in , a light entry surface 4 a is formed there, wherein the light emitting element 3 injects light into the carrier element 4 via the light entry surface 4 a. Carrier element 4 in the figure 1 The front side shown in the figure has a light exit surface 4 b lying opposite the light entry surface 4 a , which in the exemplary embodiment shown is surrounded by a ligh...

Abstract

The invention relates to a lighting module (1) for a vehicle headlamp (2), wherein the lighting module (1) has at least one lighting element (3) which can be activated by irradiation with a laser to emit visible light ) and at least one light-permeable carrier element (4), wherein the carrier element 4 has at least one light entry surface (4a) and at least a light exit surface (4b) opposite to the light entry surface (4a), wherein, At least one light emitting element (3) for incident light into the light entry surface (4a) is arranged on at least one light entry surface (4a) of the carrier element (4), wherein a) at least A light exit surface (4b) is limited by a light-permeable shield (5) surrounding the light exit surface (4b) or b) at least one light exit surface (4b) reaches as far as the side (6a to 6d), wherein at least one side (6b) has two side sections (6b', 6b'') adjoining one another, which are inclined towards one another for the purpose of forming the light-dark boundary.

Description

technical field [0001] The invention relates to a lighting module for a vehicle headlight, wherein the lighting module has at least one lighting element which can be excited by irradiation with a laser to emit visible light and at least one light-permeable carrier element, wherein the carrier element The element has at least one light entry surface and at least one light exit surface lying opposite the light entry surface. Background technique [0002] Lighting modules according to the prior art with light-emitting elements that can be excited with a laser to emit visible light have the disadvantage that the light emitted by the light-emitting element is generally non-directional and that additional components are necessary with regard to the attached optics to position or form. Contents of the invention [0003] Therefore, the object of the present invention is to eliminate this disadvantage. This object is achieved with a lighting module of the type mentioned at the ou...
