The latter collect the light falling onto the reflector arrangement (3), and distribute it uniformly over the area (8) to be illuminated. In contrast to prior ceiling luminaires without an antiglare louvre, the viewer of the new ceiling luminaire no longer sees only a brightly luminous point, but a multiplicity of luminous points which is equal to the number of the individual reflectors, the luminous intensity of a luminous point being only a small fraction of the luminous intensity of the lamp. A glare effect is thereby avoided. ...

Method and means to evenly distribute ambient illumination and to avoid bright LED beam directly into human eyes

An energy-saving LED-based device with improved support structure for high-brightness LED chips for room illumination. The improved support structure positions the LED chips in such a way that the light is emitted towards the ceiling, the floor, or any other surface, along such a path that human eyes are unlikely to cross the light path. Because the bright light is kept away from people's eyes, there is no need for shades, which absorbs some of the light produced. Two of the most common shades are the light breakers surrounding the standing lamps in residential spaces and the light breakers around the lights near the ceiling that are part of the indirect lighting. Dispensing with the shades increases the overall energy efficiency because the light energy absorption by the shade is obviated.
