    Abstract: A system includes two or more phosphor-containing white LEDs (or other color-shifting artificial light sources) selected so that their combined color shift over at least 8,000 hours (e.g., at least 10,000 hours, at least 20,000 hours, at least 30,000 hours, at least 40,000 hours, up to 200,000 hours, up to 100,000 hours, up to 80,000 hours) of operation is less than at least one of the LED's (or the other color-shifting artificial light source's) color shift over that time. Here, the combined color shift (Δ'v') over the at least 8,000 hours (e.g., at least 10,000 hours, at least 20,000 hours, at least 30,000 hours, at least 40,000 hours, up to 200,000 hours, up to 100,000 hours, up to 80,000 hours) of operation can be less than 0.007 (e.g., 0.006 or less, 0.005 or less, 0.004 or less, 0.003 or less, 0.002 or less, 0.001 or less, 0.0005 or less).

    Abstract: A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

    Abstract: A luminaire (100) includes a base (102) supporting multiple light- emitting elements (LEEs) (122); and a first wall (150-i) and a second wall (150-o) each extending along a first direction (101). The first and second walls (150-i, 150-o) have light-reflective surfaces facing each other and forming a hollow channel (152). The light-reflective surfaces have first portions (120) that curve in opposite directions, second portions (130) that are parallel, and third portions (140) that curve in like directions. The first portions (120) are arranged facing the LEEs (110) to provide an input aperture (122) that receives light from the LEEs (110). The third portions (140) are arranged to provide an exit aperture (142) that outputs output light into an ambient environment. The first and second walls (150-i, 150-o) are configured to propagate light from the input aperture (122) to the exit aperture (142).

    Abstract: A luminaire includes (i) a first optical system to output light having a first output light distribution and a second optical system arranged adjacent the first optical system and to output light having a second different output light distribution; and (ii) a first light engine optically coupled to an input aperture of the first optical system and a second light engine optically coupled to an input aperture or the second optical system, the first and second light engine to allow independent control of amounts of light provided to the first and second optical systems. Each of the first and second optical systems has an output aperture displaced by a predetermined distance along a forward direction from the corresponding input aperture to direct light received at the input aperture to the output aperture. The first and second optical systems have elongate extensions extending sideways from the forward direction.
