Patent number: 8796951Abstract: A location commissioning method for a lighting system, having several lighting arrangements, includes selecting an illuminated position, assigning the position a position id, measuring light at the position, deriving light data associated with each lighting arrangement from the measured light, associating the light data with the position id, determining light transfer data from the light data and current drive data for the lighting arrangements, and storing in a light effect setting array for the position id. A light effect setting method includes requesting a selected light effect at a selected position, receiving a position id and a target light effect setting associated with the position, deriving the associated initial light effect setting array, for example by retrieving a stored one, determining the drive data for obtaining the target light effect setting, via the light transfer data in the array.Type: GrantFiled: August 27, 2012Date of Patent: August 5, 2014Assignee: Koninklijke Philips N.V.Inventors: Lorenzo Feri, Dragan Sekulovski, Sel Brian Colak, Johan-Paul Marie Gerard Linnartz, Paulus Henricus Antonius Damink, Jorge Guajardo Merchan

Publication number: 20140056588Abstract: Proposed is a light module (110) comprising at least two primary light sources (111,112,113) capable of emitting a primary color light. This allows the light module to emit light having intensity (Y) and color coordinates (x,y) through additive color mixing of the constituent primary colors. The light module further comprises an modulator (115) capable of modulating the primary light sources enabling embedment of data in the light emitted. The modulator (115) is arranged to modulate the color coordinates of the light emitted for embedding the data. This is especially advantageous as the sensitivity of the human eye to changes in color is lower than to changes in intensity. The invention thus advantageously allows embedding the data into the light emitted from the light modules (110) of an illumination system (100) without reducing the performance of its primary function as an aid to human vision.Type: ApplicationFiled: November 1, 2013Publication date: February 27, 2014Applicant: Koninklijke Philips N.V.Inventors: Tim Corneel Wilhelmus SCHENK, Lorenzo FERI, Paulus Henricus Antonius DAMINK, Martin Maurice VERNHOUT, Dragan SEKULOVSKI

Patent number: 8461443Abstract: Method, device and system for generating a light control parameter for controlling light (20), e.g. ambient light, in response to an audio signal (A). The audio signal (A) is analyzed in order to extract a temporal evolution of semantic content of the audio signal (A). A light control parameter is then generated according to the temporal evolution of semantic content of the audio signal (A), either on-line or off-line. This enables generating light that is perceptually aligned with the audio signal, e.g. music. In a preferred embodiment spatial properties of the audio signal (A) are extracted, and separate light control parameters are generated for controlling light sources spatially positioned according to the spatial properties of the audio signal, e.g. for stereo or surround sound systems where light sources are positioned near each loudspeaker. Such embodiment enables spatial correspondence between light and audio.Type: GrantFiled: October 25, 2007Date of Patent: June 11, 2013Assignee: TP Vision Holding B.V.Inventors: Martin Franciscus McKinney, Janto Skowronek, Dragan Sekulovski, Bram Kater

Patent number: 8004209Abstract: The invention relates to a method of controlling a temporal variation of light emitted by an illumination system. The light emitted by the illumination system varies from light having a start color point (14) to light having a target color point (12). The start and target color point are defined in a first color space (XYZ, RGBvid, RGBill), which is perceptually non-uniform. The method according to the invention converts the start and target color point from the first color space to a second color space (Lab, Lch), which is more uniform to the human visual system than the first color space. The method further comprises a step of generating an intermediate color point (34, I1, I2) located on a transition-path (p, p?) within the second color space, an intermediate distance (d) between the start color point in the second color space and the intermediate color point in the second color space not being larger than a threshold distance (26).Type: GrantFiled: October 2, 2007Date of Patent: August 23, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Dragan Sekulovski, Ramon Antoine Wiro Clout

Publication number: 20100301776Abstract: The present invention relates to a location commissioning method for a lighting system, which comprises several lighting arrangements. Thus, an illuminated position, of for example a room, is selected for the performing the commissioning, which is then associated with that position. This commissioning is called Luxissioning™. The position is assigned a position id, and the light at the position is measured. Light data associated with each one of the lighting arrangements is derived from the measured light, and the light data is associated with the position id. Light transfer data is determined on basis of the light data and current drive data for the lighting arrangements and stored in a light effect setting array for the position id. A light effect setting method is also present, where there is requested a selected light effect at a selected position. For each such request data comprising a position id and a target light effect setting associated with the position is received.Type: ApplicationFiled: May 5, 2008Publication date: December 2, 2010Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Lorenzo Feri, Dragan Sekulovski, Sel Brian Colak, Johan Paul Marie Gerard Linnartz, Paulus Henricus Antonius Damink, Jorge Guajardo Merchan
