An elongated luminaire for illuminating objects in front of the luminaire, comprising a plurality of side emitting LEDs () in only one straight array mounted on an elongated base plate (). The base plate () carries two elongated reflectors () extending on either side of the array of LEDs () and parallel to the array of LEDs (). Each reflector () has a reflecting surface () directed towards the array of LEDs ().

Elongated luminaire comprising LEDs for illuminating objects in front of the luminaire

The illumination system has a plurality of light emitters (R, G, B) and a light-collimator () for collimating light emitted by the light emitters. Light propagation in the light-collimator is based on total internal reflection (TIR) towards a light-exit window () of the light-collimator. At least one light sensor () for optical feedback is placed outside the light-collimator and is arranged to receive light emitted by the light emitters exclusively through reflection at the light-exit window of the light-collimator. Preferably, the light sensor is placed substantially coplanar with the light emitters. Preferably, a side wall () of the light-collimator is provided with a protruding portion () for guiding the light reflected at the light-exit window of the light-collimator towards the light sensor. Preferably, the illumination system is provided with a reflector (). Preferably, the illumination system comprises a holographic diffuser (). Accurate sensing of the color mixing of light emitted by the illumination system is obtained.

Optical feedback system with improved accuracy

A light-guiding system comprising a plate-like light-emitting element () provided with means for emitting light through at least part of its front surface (). Light is coupled in by a plate-like light-guiding member () connected to a lateral side of said lightemitting element (). One or more interstices () are present between said light-emitting element () and said light-guiding member ().

The invention relates to the on-line analysis of meta-data that is received together with a video signal. This analysis results in an adaptation of the lighting surrounding the presentation device (). One or more characteristics of the meta-data are filtered out and translated into lighting settings of one or more light elements (), which in turn can contain one or more light sources.

Method of and system for controlling an ambient light and lighting unit

A light-guiding system comprising a plate-like light-guiding member () provided with a lateral surface for coupling in light into said light-guiding member (). The ends of a number of light transmission rods () are connected to said lateral surface, while said light-guiding member () and said light transmission rods () are one piece of the same material.

Light-guiding system comprising a number of light transmission rods

A luminaire comprises a relatively thin and flat light-emitting panel ( ) having a light-emitting window ( ) and, opposite said light-emitting window, a rear wall ( ) with opposed edge surfaces ( ). At least one of the edge surfaces ( ) is light transmitting and associated with a plurality of light sources ( , . . . ). Light originating from the light sources ( , . . . ) is spread in the panel ( ). The invention is characterized in that a plurality of deformities ( , . . . ) is provided in the panel ( ) for extracting light from the panel ( ) via the light emission window ( ). The deformities ( , . . . ) are clustered so as to form at least one light symbol ( ). The configuration of the clusters ( ) of deformities ( , . . . ) corresponds to the shape of the light symbol ( ). Preferably, the luminaire has a first and a second light-transmitting edge surface, with respectively, a first and a second plurality of light sources being associated with said surfaces. A first cluster of deformities only couples light from the first light source out of the panel, thereby forming a first light symbol, while a second cluster of deformities only couples light from the second light source out of the panel, thereby forming a second light symbol, independently of the formation of the first light symbol. The luminaire according to the invention provides independent lighting and coloring possibilities of light symbols in a single-panel luminaire.

Luminaire and light-emitting panel

The electric lamp has a light source ( ) in an outer bulb ( ). The light source ( ) is secured in an envelope ( ) by means of an insulator body ( ) in which current connection conductors ( ) are integrated and which is present in a lamp cap ( ) of the reflector lamp. The lamp cap ( ) is mechanically connected to a neck portion ( ) of the envelope ( ). The integrated insulator/current connector body ( ) enables electrical contacting, fixation, and mechanical adjustment of the light source ( ) in the envelope ( ).
