Abstract:
1. An apparatus configured to emit light, comprising: one or more linearly arranged devices configured to radiate light; one or more optical components; and a carrier structure, the carrier structure comprising: wherein the one or more linearly arranged devices and the one or more optical components are arranged in the extruded profile of the carrier structure; wherein the extruded profile is hollow and comprises an exit aperture for the egress of light from the extruded profile; and wherein the extruded profile is configured such that the one or more linearly arranged devices can be arranged inside the extruded profile at two or more positions in a cross-sectional plane of the extruded profile; wherein the two or more positions comprise a first position and a second position; and wherein the first and second positions are at different distances from the exit aperture and the first and second positions are parallel to one another and to the exit aperture in the cross-sectional plane such that both respective main radiation directions of the one or more linearly arranged devices are toward the exit aperture and are at 0° to a main radiation direction of the light from the extruded profile when the one or more linearly arranged devices are arranged at the first position and at the second position; and wherein the extruded profile comprises slots into which the one or more linearly arranged devices and the one or more optical components can be inserted in order to arrange them inside the extruded profile; wherein the slots are arranged inside the extruded profile so as to be able to arrange the devices in two or more different angular positions relative to the main radiation direction of the light from the extruded profile, wherein the two or more different angular positions comprise the first position and a third position, and wherein the slot for the third position is arranged in the extruded profile such that the main radiation direction of the one or more linearly arranged devices when in the third position is at 90° to the main radiation direction of the light from the extruded profile.
