Patent number: 10480733Abstract: Lighting systems, devices, methods and apparatus for simulating a candle flame are disclosed. The systems and methods employ spatially distributed, disjointed sets of light-emitting elements that are independently controlled with randomized control signals to simulate a candle flame by forming spatially and temporally varying lighting effects. Further, the disjointed sets are controlled such that the total light intensity is essentially maintained. In addition, systems and methods employ a transition probability model to adjust intensities of light-emitting elements in a way that accurately mimics a candle flame.Type: GrantFiled: September 30, 2015Date of Patent: November 19, 2019Assignee: SIGNIFY HOLDING B.V.Inventors: Johannes Petrus Maria Ansems, Martinus Theodorus Bennebroek, Abraham Vamattathil Scaria, Ramon Antoine Wiro Clout, Dragan Sekulovski, Tim Dekker

Patent number: 10448478Abstract: A lighting assembly (100), an LED strip, a luminaire and a method of manufacturing a lighting assembly are provided. The lighting assembly (100) is for emitting substantially white light of a controllable correlated color temperature and comprises groups of a first light source (110), a second light source (120), a third light source (130) and a controller (140). The first light source is for emitting substantially white light having a color temperature larger than 5000 Kelvin. The second light source is for emitting substantially white light having a color temperature smaller than 2250 Kelvin. The third light source is for emitting greenish light. The greenish light has a third color point in the CIE 1931 XYZ color space within an intersection of half spaces y>=1.04 x and y>=?0.0694x+0.4525. The controller is for controlling the light emission of said light sources.Type: GrantFiled: September 8, 2015Date of Patent: October 15, 2019Assignee: SIGNIFY HOLDING B.V.Inventors: Joris Hubertus Antonius Hagelaar, Abraham Vamattathil Scaria

Publication number: 20180347771Abstract: Lighting systems, devices, methods and apparatus for simulating a candle flame are disclosed. The systems and methods can employ spatially distributed, disjointed sets of light-emitting elements that are independently controlled (526) with randomized control signals to simulate a candle flame by forming spatially and temporally varying lighting effects. Further, the disjointed sets can be controlled (526) such that the total light intensity is essentially maintained. In addition, systems and methods can employ a transition probability model (508) to adjust intensities of light-emitting elements in a way that accurately mimics a candle flame.Type: ApplicationFiled: September 30, 2015Publication date: December 6, 2018Inventors: Johannes Petrus Maria ANSEMS, Martinus Theodorus BENNEBROEK, Abraham Vamattathil SCARIA, Ramon Antoine Wiro CLOUT, Dragan SEKULOVSKI, Tim DEKKER

Publication number: 20170321867Abstract: The invention provides a luminaire (100) comprising an array (102) of light exit windows (104, 104?, 104?, 204, 304?, 304?, 404?, 404?, 604, 804?, 804?, 804??, 904?, 904?, 1004, 1004?, 1004?), wherein each light exit window comprises a material adjustable between at least a first state having a first translucence and a second state having a second translucence and an electrode arrangement (112) for adjusting said translucence of the material. Such a luminaire (100) can provide differing lighting effects whilst providing illumination and, additionally, differing aesthetic effects when viewed under ambient lighting. There is also provided a method of configuring the luminaire (1100), a computer program product for implementing the method (1200), a computing device including the computer program product (1300) and a lighting system comprising the luminaire (100).Type: ApplicationFiled: November 9, 2015Publication date: November 9, 2017Inventors: JORIS HUBERTUS ANTONIUS HAGELAAR, JOHANNES PETRUS MARIA ANSEMS, ABRAHAM VAMATTATHIL SCARIA, AART JAN VROEGOP
