Releasable optical element

摘要

An optical element (100) for releasable connection to a lighting module (103), the optical element comprising; an outer member (102) having a cylindrical portion, the cylindrical portion having a shoulder portion (104) extending towards a central axis of the cylindrical portion; an inner member (110) having a cylindrical portion at least partially arranged within the cylindrical portion of the outer member (102); wherein the optical element further comprises at least one deformable member (108) arranged within the cylindrical portion of the outer element adjacent to the shoulder; and at least one of the inner and the outer member comprising an optical member (120) for modifying light emitted from the lighting module; and wherein the inner member is movable in an axial direction in relation to the outer member to compress the deformable member between a base surface of the cylindrical portion of the inner member and the shoulder portion of the cylindrical portion of the outer member.

1. An optical element for releasable connection to a lighting module, said optical element comprising;
an outer member having a cylindrical portion, said cylindrical portion having a shoulder portion extending towards a central axis of said cylindrical portion; an inner member having a cylindrical portion at least partially arranged within said cylindrical portion of said outer member; wherein said optical element further comprises at least one deformable member arranged within said cylindrical portion of said outer element adjacent to said shoulder; and at least one of said inner and said outer member comprising an optical member for modifying light emitted from said lighting module; wherein said inner member is movable in an axial direction in relation to said outer member to compress said deformable member between a base surface of said cylindrical portion of said inner member and said shoulder portion of said cylindrical portion of said outer member; and to expand said deformable member in a direction perpendicular to the axial direction such that the outer member is releasably connected to the inner member through a friction between deformable member and the inner member.
