  • Color selection input device and method
    Patent number: 8730256
    Abstract: The invention relates to color selection input, for example by means of a color selection wheel or pad, particularly for a lighting system. The invention provides color selection means (10) representing selectable colors in terms of hue gradation (12) along a direction thereof, wherein the hue gradation is adapted to user preferences in that the hue gradation is divided into non-equal segments (20, 22) with segments of user preferred hue (20) larger than segments of non user preferred hue (22). The invention has the main advantage that the input of a color selection may be better adapted to user preferences.

  • Lamp assembly
    Patent number: 7878688
    Abstract: The invention relates to a lamp assembly (1) for illuminating a surface (S) comprising a chamber (3) accommodating a plurality of light-emitting diodes (11R, 11G, 11B) capable of emitting visible light. The lamp assembly comprises diffusing means (12) capable of diffusing said visible light of said light-emitting diodes to produce diffuse light (D), and said chamber further accommodates collimation means (5) arranged to collimate at least a portion of said diffused light for illuminating said surface. The lamp assembly is especially suitable for ambiance and atmosphere lighting applications.

  • METHOD AND SYSTEM FOR ADJUSTING THE LIGHT SETTING FOR A MULTI-COLOR LIGHT SOURCE
    Publication number: 20090168415
    Abstract: The present inventions relates to a method for adjusting the light setting for a multi-color light source, which method comprises receiving input from a user related to at least one of white color, hue, and chroma, and adjusting white color, hue, and chroma of the light source in accordance with the user input. The method is characterized in the step of automatically changing a current hue and chroma level when the user input is received. This automatic change makes possible to render the subsequent adjustment in setting perceivable for the user, which facilitates the adjustment of the light source. The present invention also relates to a corresponding system and computer program product.
