SIMULATION DEVICE FOR LIGHTING OPERATION

摘要

PURPOSE:To visualize a flow of light and its illuminance in three dimensions and to easily judge the lighting state in a lighting space by setting virtual spheres at three-dimensional grating points in the lighting space, calculating the illuminance on the virtual spheres, and classifying the surfaces of the virtual spheres corresponding to the calculated illuminance distribution by colors. CONSTITUTION:The illuminance calculated as to all the surfaces of respective virtual spheres B by a virtual sphere total illuminance calculating means which sets the virtual spheres B at three-dimensional grating points G in the lighting space A and calculates the illuminance on the virtual spheres B is added to calculate the total illuminance on the surfaces of the respective virtual spheres B. Then an illuminance distribution color classifying means classifies colors corresponding to the illuminance distribution on the surface of each virtual sphere B. The virtual spheres B which are classified by the colors has the highest illuminance at the parts facing a light source L and are represented by circles and then represented by ring shapes as the illuminance distribution becomes lower, thereby representing the flow direction and illuminance values of the light in three dimensions. Then the simulation result of the calculating means is displayed by an output means.
