Abstract
The invention relates to an optical system (2) for lighting units (S), having: an optical support (3) which extends linearly along a longitudinal axis (A) between a light inlet opening (LE) and a light outlet opening (LA) and which delimits a receiving area (R) for receiving optical elements (4, 5) between the openings (LE, LE), wherein an inner wall (30) of the optical support (3) facing the receiving area (R) has at least two structural sections (31), which are axially offset to each other with respect to the longitudinal axis (A), for releasably mounting a respective optical element (4, 5) in the receiving area (R).
Claims25
An optical system (2) for lighting units comprising:
- an optics carrier (3) which extends rectilinearly between a light inlet opening (LE) and a light outlet opening (LA) along a longitudinal axis (A) and delimits a receiving space (R) between the openings (LE, LE) for receiving optical elements (4, 5), wherein an inner wall (30) of the optics carrier (3) facing the receiving space (R) has at least two structural sections (31) arranged axially offset relative to each other with respect to the longitudinal axis (A) for releasably mounting an optical element (4, 5) in the receiving space (R);
- at least two optical elements (4, 5), each of which is inserted into one of the structural sections (31), so that they are axially arranged spaced apart from each other, viewed axially with respect to the longitudinal axis (A), in the receiving space (R), such that light coupled in via the light inlet opening (LE) and coupled out again via the light outlet opening (LA) at least partially passes through the at least two optical elements (4, 5) to optically influence the light;
- wherein the optical elements (4, 5) are a Fresnel lens and a diffuser lens (5).
