Abstract
A light irradiation heating process in which, even in the case of an asymmetrical physical property of an article to be treated, uniform heating is possible, or in which heating can be performed such that the article acquires a desired physical property after heat treatment. Based on the measured value of the local physical property of the article to be treated, the emissivity distribution is obtained and the distribution pattern of the light intensity on the article to be treated is determined. According to this light intensity pattern, the individual intensity of the light emitted from respective light emitting parts of lamp units of the heating device are determined beforehand. According to this determined result, the intensity of the light emitted from the respective light emitting parts of the lamp units are controlled individually, and thus, the article to be treated is irradiated with light.
