Abstract

Illumination device (10) for a motor vehicle headlight, wherein the illumination device (10) comprises the following:

a heat sink (50) with several light sources (20) and projection optics (60),a holding body (70) for holding the projection bodies (60) and the heat sink (50), wherein the heat sink (50) is attached to the holding body (70) by means of an attachment device, wherein the attachment device comprises at least three attachment pairs (100a), which are arranged in a cross-section orthogonal to the main emission direction (X) at the same distance to the optical axis (A) of the projection optics (60) about the optical axis (A), wherein an attachment pair (100a) comprises a rib (100) projecting from the holding body (70), which rib extends along an extension plane (E) away from the holding body (70) against the main emission direction (X), and comprises a fixing recess (200) corresponding to the projecting rib (100), which is arranged on the heat sink (50) and passes through it along an axis (X1) parallel to the main emission direction (X), wherein, in the attached state (P1), the rib (100) is in engagement with the fixing recess (200) for each attachment pair (100a) in such a way that the rib (100) passes through the corresponding fixing recess (200), that a respective spatial volume (210) is formed between the rib (100) and the fixing recess (200) on opposite sides of the extension plane (E) of the rib (100), in which spatial volumes (210a) the adhesive (300) for fixing the rib (100) to the fixing recess (200) is arranged.
