Stochastic dynamic atmosphere

摘要

The invention concerns a lighting device for creating dynamic atmospheres, the lighting device comprising: a light source adapted to operate in a plurality of color states, the light source emitting differing colors for each color state; a controller for controlling the color state of the light source; the controller comprising a random generator to provide a transition between a previous and a subsequent state, wherein the controller is adapted to provide the transition based on probabilistic output provided by the random generator implementing a stochastic model, the probabilistic output depending on the previous color state. In addition, a method is provided for generating the stochastic model; and a method for creating dynamic atmospheres based on probabilistic output provided by the stochastic model.

1. A lighting device for creating dynamic atmospheres, said lighting device comprising:
a light source adapted to operate in a plurality of color states, the light source emitting differing colors for each color state; a random generator; a controller for controlling the color state of the light source, the controller adapted to provide a transition between a previous and a subsequent color state based on a output provided by the random generator; a stochastic model defining transitions between subsequent states is implemented in the controller; wherein the controller is adapted to provide the transition between a previous and a subsequent color state such that, based on the outcome of the random generator and starting from a present color state, the controller is arranged to decide and control by the stochastic model which subsequent color state is realized based on the present color state; a multimedial output device driven by multimedial sources; a clustering circuit for clustering the multimedial output according to a predefined aspect; a computational circuit for computing a statistic on subsequent transitions between the clusters of the multimedial sources; a processing circuit for generating probability parameters associated with the computed statistic; and an output circuit for outputting the probability parameters to the random generator so as to implement the stochastic model.
