The lamp component includes a light orienting element having a light incident end, a light output end opposite the light incident end, and a side surface extending between the light incident and light output ends; and a housing configured to position the light orienting element adjacent a light source. The housing is at least partially translucent, and includes at least one sidewall and a main wall facing the light output end. The light orienting element is configured to deflect a fraction of the incident light towards the light output surface to be projected through the main wall as to direct light, and a fraction of the light towards the at least one housing sidewall to be projected as indirect light. The light orienting element is a first part formed by extrusion in a first direction, and the housing is a second part formed by extrusion in a first direction.

LED lamp component having reflective/refractive element within translucent housing

In a lighting arrangement, in particular for escape route lighting, comprising a light source and an optical element assigned to the light source, said optical element being designed to emit asymmetrically the light emitted by the associated light source, the optical element can be positioned in different ways.

Lighting arrangement, in particular for escape route lighting

The invention relates to a luminaire () having a housing which is closed by a translucent cover (). The housing accommodates a light source and control gear (), the light source being formed from a plurality of LEDs () arranged on at least one circuit board (). According to the invention the light from the LEDs () is coupled into at least one light guide () which extends from the cover () towards the LEDs (). The coupled-in light from the LEDs () is guided in the light guide () to the cover () and is preferably emitted diffusely.

Luminaire

A luminaire which has at least one first LED light source for emitting a first light, at least one first light-directing element for influencing the direction of the first light, at least one second LED light source for emitting a second light, and at least one second light-directing element for influencing the direction of the second light. The first light-directing element is in this case configured in such a way that it affects an asymmetric light output of the first light. The second light-directing element has an identical configuration to the first light-directing element and is arranged in a position rotated through 180&#xb0; relative to the first light-directing element. When the first LED light source is switched ON and the second LED light source is switched OFF, an asymmetrical light output which is particularly suitable as task lighting can be achieved by the luminaire.

LED luminaire having differently settable light distributions

A light-influencing element for influencing the light emission of essentially point light sources having at least two lenses which are juxtaposed and integrally connected to each other, each having a cavity defining a light entrance section of the lens, and a light exit surface opposite the light entrance section, at least two of the lenses being designed differently with regard to their light entrance sections.

Light-influencing element for influencing the light emission of essentially point light sources

An arrangement for emitting light comprising at least one LED-light source and at least one lens arranged in front of the LED light source in the light-emitting direction. A reflector is arranged in front of the lens in the light emitting direction for influencing the light emitted from the lens.

Arrangement for emitting light

A luminaire having a box-like luminaire housing for receiving at least one elongate light source and at least one reflector surface arranged&#x2014;seen from the region to be illuminated&#x2014;neighboring the light source, the luminaire housing forms a light exit opening which is closed by a light exit element. The light exit element has in a first emission region, located in substance in front of the light source, a first light emission characteristic, and has in a second emission region, separate from the first emission region, a second light emission characteristic different with respect to the first light emission characteristic.
