  • Patent number: 8931926
    Abstract: A reflector luminaire with a light-emitting means and a reflector, which reflects light from the light-emitting means which is incident on said reflector in a predetermined emission direction and which has a rim (2) which points towards the emission direction makes it possible to perform particular lighting tasks, for example the uniform illumination of a rectangular illumination area by virtue of the fact that the reflector comprises a plurality of differently designed segments (7), which are calculated individually with respect to the light-emitting means for defined illumination of a predetermined area, and by the fact that the segments (7) are joined to one another by transition sections (8), by means of which the predetermined reflecting total surface area of the segments (7) is reduced by less than ¼.

  • Patent number: 8926159
    Abstract: A front and back reflector are arranged to form a hollow light recycling cavity having an output region, and one or more light sources (e.g. LEDs) are disposed to emit light into the cavity. In one aspect, the back reflector has a design characterized by a first and second parameter. The first design parameter is a ratio of the collective emitting area of the light sources Aemit to the area of the output region Aout, and Aemit/Aout is preferably from 0.0001 to 0.1. The second design parameter is SEP/H, where H is the depth of the recycling cavity, and SEP is an average plan view source separation associated with the light sources. Other aspects of the disclosed extended area light sources are also described.
