The invention relates to an aid for the nutrition of a patient suffering from mental disorders. According to the invention, the vessel (14) containing food is presented on a holder (12), and a lighting device (16) with a coloured beam is combined with said device for lighting the vessel and arousing the patient's interest.
摘要:
The invention relates to a luminaire comprising a plurality of light sources fixedly locatee in a plurality of positions and comprising at least an electroluminescent diode. Said sources are focused by the same optical system fixed relative to the plurality of sources. Said luminaire comprises electronic means for dimming sources in their emission intensity independently of one another and as a function of their respective positions relative to said optical system. The invention provides an output beam having a dimmable photometric distribution in time and in space at the output of said optical system.

A string assembly of "daisy-chained" light emitting modules and a display comprising a plurality of string assemblies are provided.
摘要:
Meeting a target color point using more than 3 primary light sources is achieved by calculating permutations of light sources, calculating for each of the permutations the contributions of the light sources to meet the color point, adding up the contributions of the light sources separately into an overall contribution, and operating the light sources according to their overall contributions.
摘要:
Die Erfindung betrifft einen LED-Lichtleiter (2) zum Durchmischen von Licht mehrerer LEDs (8), der einen Lichtleiter mit einer Lichteintrittsseite (4) und einer von der Lichteintrittsseite beabstandeten Lichtaustrittsseite (6) und mehrere an der Lichteintrittsseite angeordneten LEDs aufweist, wobei der Umfang der Lichteintrittsseite und der Umfang der Lichtaustrittsseite durch Grenzflächen des Lichtleiters verbunden sind, welche eine Basislinie des Lichtleiters mantelförmig umschließen, die die Längserstreckung des Lichtleiters zwischen der Lichteintrittsseite und der Lichtaustrittsseite definiert, wobei die Grenzflächen auf der zur Basislinie weisenden Seite lichtreflektierende Strukturen aufweisen, an denen Licht der LEDs auf dem Weg von der Lichteintrittsseite zu der Lichtaustrittsseite mehrfach reflektiert wird, und die lichtreflektierenden Strukturen auf der zur Basislinie weisenden Seite eine Abfolge von Erhebungen (12,12',12'') und/oder Vertiefungen aufweisen.
摘要:
The invention relates to a control device (1) for controlling the hue (H) of light (L) emitted by a light source (2). The control device comprises a hue selection surface (20) capable of displaying one or more hues available for said light of said light source and interaction detection means (21) for detecting interaction between said hue selection surface and a user of said control device in selecting said hue for said light of said light source. The control device (1) allows the user to select the desired hue for the light source simply by interacting with the hue selection surface that displays the available hues. Consequently, the control device can be operated easily and intuitively.
