Embodiment Construction

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0030] The lighting environment evaluation method of the embodiment includes the following steps: the step of setting a specific surface in the lighting space of the evaluation object; the step of setting an observation set point on the specific surface; calculating the illuminance of the observation set point based only on the indirect light generated by the reflector, using information related to reflectors of light in the space and information related to lighting fixtures installed in the lighting space, A step of using the calculated result as an indicator of the brightness of the lighting space.

[0031] In addition, the step of setting the brightness feeling as an index is a step of calculating the first illuminance of the observation measurement point based on direct light from the light from the lighting fixture and indirect light by the reflector. ; ...

Abstract

The disclosed lighting environment evaluation method involves: a step in which a prescribed surface is designated in a lighting space to be evaluated; a step in which a designated observation point on the aforementioned prescribed surface is designated; and a step in which, on the basis of information relating to reflective objects that reflect the light in the aforementioned lighting space and information relating to the lighting equipment provided in the aforementioned lighting space, the illuminance at the aforementioned designated observation point from only the indirect light from the aforementioned reflective objects is calculated, and the calculation result is set as the index of brightness sensation of the aforementioned lighting space.

Description

technical field [0001] Embodiments of the present invention relate to a lighting environment evaluation method and a lighting environment evaluation device. Background technique [0002] Lighting (surname) has a great influence on the comfort of an office environment or a residential environment. As an evaluation method of this lighting environment, horizontal plane illuminance may be used. In the Japanese Industrial Standard (JIS), an illuminance standard using horizontal plane illuminance is prescribed for indoor lighting and the construction industry. [0003] In the lighting design, the evaluation method of the lighting environment using the horizontal plane illuminance is mainly applied. However, the horizontal plane illuminance is an index indicating the light beam per unit area incident on the floor or the tabletop, not the light reaching the human eye, and cannot always properly evaluate the impression of space. [0004] On the other hand, in recent years, an eval...
