Abstract
In a lighting arrangement, in particular for escape route lighting, comprising a light source and an optical element assigned to the light source, said optical element being designed to emit asymmetrically the light emitted by the associated light source, the optical element can be positioned in different ways.
Claims19
A lighting arrangement in the form of an escape sign luminaire, the lighting arrangement comprising:
- a circumferential frame for supporting one or more transparent panes for light-delivery, wherein the circumferential frame and the one or more transparent panes form a housing;
- two light sources arranged in an interior of the housing;
- and
- two lenses respectively associated with the light sources,
- wherein the lenses are designed to asymmetrically radiate light that is emitted from the associated light source, wherein the lenses are arranged on the frame, and wherein the lenses can be positioned in four different positions on the frame, the four different positions rotated 90 degrees relative to one another about a longitudinal axis that is defined by the associated light source, and
- wherein each of the lenses comprises a base, a first portion that extends outwardly from the base in a first direction, and a second portion that extends outwardly from the base in a second direction opposite the first direction, the first portion defining a light-entry region for the light emitted from the associated light source, and the second portion defining a light-exit region for the light.

A lighting arrangement in the form of an escape sign luminaire, the lighting arrangement comprising:
- a circumferential frame for supporting one or more transparent panes for light-delivery, wherein the circumferential frame and the one or more transparent panes form a housing;
- at least one light source arranged in an interior of the housing;
- at least one lens associated with the at least one light source, the at least one lens being configured to asymmetrically radiate light emitted from the at least one light source, and
- wherein the at least one lens comprises a base, a first portion that extends outwardly from the base in a first direction, and a second portion that extends outwardly from the base in a second direction opposite the first direction, the first portion defining a light-entry region for the light emitted from the at least one light source, and the second portion defining a light-exit region for the light, and
- wherein the at least one lens can be positioned in a plurality of different rotational positions on the frame.
