<p>PURPOSE:To precisely calculate illuminance and luminance by conducting environmental analysis of light in consideration of mirror surface reflection so as to determine the light quantity reaching each surface of an emitted light at the time of simulating natural lighting. CONSTITUTION:A determined surface selected from each surface of divided environmental spaces of an analyzing target on the basis of a determined standard related to light quantity is used as a light source 1. A Light is emitted in determined plural directions from this light source, and each surface which each light reaches is searched to operate the light quantity reaching this surface. Thereafter, the reaching light quantity of a determined surface selected from each surface on the basis of a determined standard is used as a light source to operate the reaching light quantity of each surface, and this procedure is repeated to provide a final light quantity of each surface. When a reaching surface of the light having a determined angle from the light source 1 of a light environment analyzing device is determined, thus, the light in the determined angle direction is arrived to a surface 2 preliminarily determined as a mirror surface, and this light is reflected. This is repeated, and the surface of the light reaching at a new incident angle is used as the reaching surface from the light source 1.</p> |
