The present disclosure is directed to examples of an apparatus. In one embodiment, the apparatus includes a light entry segment that receives light emitted from a light emitting diode (LED), a total internal reflection (TIR) segment to reflect the light emitted from the light emitting diode towards an optical axis of the LED, and a light redirection segment to redirect the light emitted from the light emitting diode and the light reflected by the TIR segment at an angle greater than 45 degrees relative to the optical axis of the LED and greater than 90 degrees along a horizontal axis.

Lighting devices that comprise a light source and a reflector, the reflector comprising first, second and third reflector regions. In some devices, a first portion of light is reflected by the first region and then by the third reflector region, a second portion of light is reflected by the second region and forms a primary beam, and at least 5% of the first portion of light that is reflected by the third region is within the primary beam of light. In some devices, at least 5% of all light reflected by the first reflector region travels from the first reflector region directly to the third reflector region. In some devices, at least 5% of all light reflected by the third reflector region traveled directly from the first reflector region to the third reflector region. In some devices, the reflector comprises means for providing the features described above.

A generic reflector comprises a light inlet end, a light outlet end with at least one substantially rectangular light outlet opening, an optical axis, and a reflector surface which extends between the light inlet end and the light outlet end, where the reflector surface in a plane perpendicular to the optical axis defines a polygon. The reflector surface is formed such that the polygon between the light inlet end and the light outlet end at least in sections rotates about an axis of rotation which is oriented parallel to the optical axis. The invention also relates to an arrangement comprising at least two reflectors and a luminaire with a reflector and a light source, comprising an LED.

The invention also relates to an arrangement comprising at least two reflectors and a luminaire with a reflector and a light source, comprising an LED.

A luminaire includes multiple light-emitting elements (LEEs); a base supporting the LEEs; and a first wall and a second wall each extending along a first direction from a respective first end facing the LEEs to a respective second end. The first and second walls have light-reflective surfaces facing each other. In one or more cross-sectional planes parallel to the first direction, the light-reflective surfaces of the first and second walls have first portions that curve in opposite directions, second portions that are parallel, and third portions that curve in like directions. The first portions are arranged facing the LEEs to provide an input aperture that receives light from the LEEs. The third portions are arranged to provide an exit aperture that outputs output light into an ambient environment. The first and second walls are configured to propagate light from the input aperture to the exit aperture.
