Abstract: 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.

Abstract: The present invention relates to assisting a user in selecting a lighting device design by providing a lighting device design based on a model or image of a lighting device design (e.g. the user uploading an image of an existing lighting device in his/her home). The lighting device design of the model or image is analyzed in order to determine a lighting device design related variable (e.g. type, shape or color of lighting device design). This variable is then used to select a lighting device design from a set of lighting device designs (e.g. to select a lighting device design of the same color, from an electronic catalogue of lighting device designs); or to generate a lighting device design (e.g. to generate a lighting device design that is a copy of the lighting device design in the image, only smaller and in a different color). The invention further includes a system and computer program product for implementation of this method.
