Methods and systems for an automated design, fulfillment, deployment and operation platform for lighting installations
View Patent ↗A platform for design of a lighting installation generally includes an automated search engine for retrieving and storing a plurality of lighting objects in a lighting object library and a lighting design environment providing a visual representation of a lighting space containing lighting space objects and lighting objects. The visual representation is based on properties of the lighting space objects and lighting objects obtained from the lighting object library. A plurality of aesthetic filters is configured to permit a designer in a design environment to adjust parameters of the plurality of lighting objects handled in the design environment to provide a desired collective lighting effect using the plurality of lighting objects.
1. A method for incrementally reconstructing a near-field illumination effect of a light source, comprising:
capturing, by an indirect luminance collection device, a first occurrence of multi-dimensional luminance of the light source, with the indirect luminance collection device being disposed at a first position relative to the light source;
capturing, by the indirect luminance collection device, a second occurrence of multi-dimensional luminance of the light source, with the indirect luminance collection device being disposed at a second position relative to the light source;
producing a representation of the near-field illumination of the light source by applying a multi-dimensional near-field illumination reconstruction algorithm to the captured occurrences of multi-dimensional luminance of the light;
storing the representation in a computer accessible non-volatile memory; and
repeating the capturing the first occurrence, capturing the second occurrence producing the representation, and storing the representation for a plurality of positions relative to the light source to produce a model of near-field illumination of the light source.
