A luminaire for generating direct lighting and indirect lighting including an LED light source for generating light and a light guide plate having a first main surface and a second main surface, which is connected to the first main surface marginally via a narrow side face, wherein the LED light source is arranged in such a way that the light is radiated into the light guide plate via the narrow side face and subsequently one part of the light is emitted for generating the direct lighting via the first large main surface. Furthermore, a reflector is provided, which is arranged adjacent to the second main surface, wherein the reflector has at least one light-transmissive region configured in such a way that a further part of the light is emitted for generating the indirect lighting via the second main surface through the light-transmissive region.

Luminaire for generating direct lighting and indirect lighting

A flat reflector element for planar arrangement on an LED circuit board has light-passage openings that correspond to the positions of the LEDs, wherein projecting contact protection elements are provided at the periphery of each of said light-passage openings.

A light fitting has an LED light source for generating light, and a light-guiding panel, the LED light source being arranged in such a way that the light is coupled into the light-guiding panel. In addition, a support element for supporting the light-guiding panel and an LED light source carrier element are provided, the LED light source carrier element being mounted such that it is displaceable relative to the support element.
