Embodiment approach

[0027] First, use figure 1 with figure 2 The configurations of the lighting evaluation system 1 and the lighting evaluation device 100 according to the embodiment will be described. figure 1 It is a schematic diagram which schematically shows the structure of the illumination evaluation system which concerns on embodiment. figure 2 It is a block diagram showing the basic configuration of the lighting evaluation device according to the embodiment.

[0028] [Lighting evaluation system, lighting evaluation device]

[0029] Such as figure 1 As shown, the illumination evaluation system 1 is configured to include an illumination evaluation device 100 and an illumination light source 200 , and evaluates illumination light irradiated from the illumination light source 200 . In the present embodiment, the illumination evaluation device 100 evaluates the quality of the illumination light from the illumination light source 200 based on the burden on the eyes of the observer P pe...

Deformed example 1

[0102] Next, use Figure 7 Modification 1 will be described. Figure 7 It is a block diagram showing the basic configuration of the lighting evaluation device according to Modification 1. FIG.

[0103] Illumination evaluation device 100A according to this modified example is configured by further adding an illumination condition measurement unit 60 for measuring illumination conditions to illumination evaluation device 100 according to the above-mentioned embodiment.

[0104] The lighting condition measuring unit 60 measures, for example, lighting conditions in the lighting area 310 irradiated by the lighting light source 200 . Specifically, the lighting condition measuring unit 60 measures lighting conditions such as illuminance, color temperature, color rendering, wavelength, illuminance gradient, flicker (flicker frequency), or three primary colors of light in the lighting area 310, and inputs the lighting conditions into the lighting condition Acquisition unit 40 .

Deformed example 2

[0109] Next, use Figure 8 Modification 2 will be described. Figure 8 It is a block diagram showing a basic configuration of an illumination evaluation device according to Modification 2.

[0110] An illumination evaluation device 100B according to this modified example is configured by further adding an observer information input unit 70 for inputting observer information on an observer P to the illumination evaluation device 100 according to the above-mentioned embodiment. The observer information is, for example, the age, sex, eyesight, whether or not the observer P wears glasses, an identifier, and the like. The observer information input unit 70 is, for example, a user interface such as a keyboard, a mouse, or a touch panel.

[0111] In this modified example, the storage unit 30 stores the observer information input from the observer information input unit 70 in association with the average viewing distance Xa calculated by the average viewing distance calculation unit...

Abstract

The present invention is provided with a line-of-sight distance measurement unit (10) for measuring a line-of-sight distance which is the straight-line distance between the viewpoint position of an observer performing the visual work of visually recognizing a visual recognition object arranged in an illumination region to which illuminating light from an illuminating light source is radiated and an arbitrary position on the visual recognition object, an average line-of-sight distance calculation unit (21) for calculating an average line-of-sight distance which is the average value of the line-of-sight distance measured by the line-of-sight distance measurement unit (10) in a visual work time for which the visual work is performed, a storage unit (30) for storing an evaluation reference which is that the burden on the eyes of the observer increases the shorter the average line-of-sight distance is, and an evaluation unit (22) for evaluating the quality of the illuminating light from the average line-of-sight distance calculated by the average line-of-sight distance calculation unit (21) on the basis of the evaluation reference stored in the storage unit (30).

Description

technical field [0001] The present invention relates to an illumination evaluation device and an illumination evaluation method for evaluating illumination light, and a program for executing the illumination evaluation method. Background technique [0002] Conventionally, studies have been conducted on how illuminating light affects observers when they perform visual work (reading, etc.) for a fixed period of time in an illuminated environment, but no suitable evaluation method for evaluating illuminating light has been known. [0003] Conventionally, there is known a technique for checking the observation method of an observer observing an object under an illumination environment (Patent Documents 1 and 2). The techniques described in Patent Documents 1 and 2 are techniques for evaluating an observer's observation method for observing an object under an illumination environment based on the visual performance of the observer, not techniques for evaluating illumination light...
