摘要： A lens (1) comprising a centrally extending axis (A) being perpendicular to a lens axis (L) of the lens, the lens being adapted for retracting light rays from a light source positioned off-axis with respect to the centrally extending axis, the lens comprising a first plurality of slits (21, 22, 23, 24) extending entirely in an interior of the lens and comprising a length (l) extending perpendicular to the centrally extending axis, a width (w) extending parallel to the centrally extending axis and a thickness (t) extending perpendicular to both the length and the width, the first plurality of slits being mutually parallel and covering between 40% and 60% of a plane in which both the centrally extending axis (A) and the length (l) and width (w) of the first plurality of slits (21, 22, 23, 24) extend.

摘要： A light emitting device comprising a base, a rod-shaped heat sink element extending from the base along a longitudinal axis of the light emitting device, the rod-shaped heat sink element comprising N sides. The N sides comprise at least one top side which in an assembled condition of the light emitting device faces away from an exit window of the light emitting device, at least one bottom side which in an assembled condition of the light emitting device faces towards an exit window of the light emitting device, and at least two mutually opposite sides extending between said at least one top side and said at least one bottom side. The N sides comprise M LED arrays, each comprising a plurality of LEDs, each LED of the plurality of LEDs comprising a respective light output surface arranged facing in a main direction. The at least one first LED array comprises a plurality of side emitting LEDs, the at least one second LED array comprises a plurality of top emitting LEDs and the at least one third LED array and the at least one fourth LED array each comprises a plurality of either side or top emitting LEDs.

摘要： A lighting module (1) for connecting to a luminaire, the lighting module extending along a longitudinal axis (LA) and comprising: a base (3) for connecting the lighting module (1) to a socket (11) of the luminaire (10); a central body (4) carrying at least a first light source (21) and a second light source (22), wherein the first light source (21) is configured to emit first light having a first light distribution with a first main direction pointing away from the longitudinal axis (LA), and the second light source (22) is configured to emit second light having a second light distribution with a second main direction pointing away from the longitudinal axis (LA), the first and second main directions being different from one another; and an optical element (6) including at least one optical portion (61) and a cover portion (62) extending all around the central body (4) and said optical element (6) being rotatable about the longitudinal axis (LA) in relation to the central body (4), the at least one optical portion (61) having an optical property, such that the optical portion (61) is configured to affect light emitted from at least one of the light sources, the at least one optical portion (61) extends in an angular area around the longitudinal axis (LA), and the cover portion (62) is configured not to affect light emitted from the remaining sources.
