OPTICAL ELEMENT FOR INFLUENCING THE LIGHT EMITTED BY AN EXTENDED ILLUMINATION SOURCE

摘要

an optical element (10) to influence the lichtabgabe an elongated light source, particularly one or more oblong led printed circuit boards (50) in a longitudinal direction and is extended in cross section about trapezartig trained with one of the light source can be lichteintritts area (11), a ausnehmung (12) with a curved surface (13) inone of the lichteintrittsbereich (11) opposite lichtabstrahlflu00e4che (15) which has a curved shape (16) in the linsenartige freiformoptiken (17) are overlaid, and two of the lichteintrittsbereich (11) to the lichtabstrahlflu00e4che (15), it is also the kru00fcmmten surfaces (21, 22).
