Primary optical assembly in motor vehicle lighting device, and motor vehicle lighting device with the same

The invention relates to a primary optical assembly (10) in a motor vehicle lighting device (1). The primary optical assembly comprises a plurality of elongate primary optical elements (12) arranged side by side and/or one above the other, wherein each of the elongate primary optical elements (12) has a near end (13), a far end (15) and a cross section which is gradually increased from the near end to the far end. It is proposed that the primary optical elements (12) are produced from a dimensionally stable, but elastically deformable, transparent materials and are positioned and fastened to alight source (100) or a light source carrier (104) of the lighting device (1) by means of a holder (20), wherein the holder (20) is provided with holding elements (22) for highly accurate positioningof the primary optical elements (12) in the region of the far ends (13). 本发明涉及用于安装在机动车照明装置(1)中的初级光学组件(10)，初级光学组件包括多个并排布置和/或上下叠置的长形的初级光学元件(12)，初级光学元件分别具有近端(13)和远端(15)以及从近端(13)朝向远端(15)逐渐增大的横截面。提出，初级光学元件(12)由形状固定的但是可弹性变形的透明材料制成，
