LIGHTING APPARATUS FOR GENERATING NATURAL LIGHT

摘要

PURPOSE: A lighting apparatus is provided to enable a person to confirm the condition of health accurately by taking a picture of the iris and a face of the person at the natural light without a repeated test. CONSTITUTION: A natural light generating filter(24) is disposed at a front part of an ultraviolet cutting filter(23) of a lighting apparatus and generates the natural light. A spectrum characteristic of a transmitted light of the natural light generating filter(24) is coated such that an intensity distribution rate of light is increasing lowered at right and left wavelength bands at the top of 550mm. A thermal absorption filter(22) is configured to cut infrared rays or absorb a heated line, and the ultraviolet cutting filter(23) is configured to cut ultraviolet rays.
