Abstract: A tubular light comprises an elongate light source (10) and a tubular housing (18) around the light source. An optical beam shaping arrangement (20) is provided within the housing. It has an effective focal distance, in the plane perpendicular to the length axis, which varies in dependence on the angular position around the optical beam shaping arrangement. The effective focal distance is longer for light in a light output optical axis direction than for light output laterally to the sides of the light output optical axis. This means the beam shaping, e.g. collimation, is greater at the edges of the light output beam than in the middle, so there is light mixing within the output beam.

Abstract: A lighting device has at least two lighting strips, which are slidable relative to each other and overlap in a region of overlap so that the overall length may be adjusted. The combined light intensity per unit length of the lighting strips in the region of overlap corresponds to the light intensity per unit length of the first and second lighting strips outside the region of overlap. This arrangement makes sure the combined light output in the region of overlap is the same as where the lighting strips do not overlap. In this way, the overall device is reversibly and repeatedly extendable and retractable and maintains a relatively constant light output per unit length.

Abstract: A luminaire comprises a first lighting module for providing a first lighting effect such as task lighting. The first lighting module has a front light exit face and a support structure with a rear reflective portion. A second lighting module is for providing a second lighting effect such as decorative lighting, directed to the reflective portion of the support structure. The luminaire is capable of producing the two different lighting effects in different directions.
