    摘要： A light irradiation device includes a laser light source configured to emit laser light; and a light diffusion member configured to convert the laser light into diffusion light. Light based on the laser light is emitted to an outside from a light output unit via an output optical path or two or more output optical paths including an optical path which the diffusion light passes through. The light diffusion member includes a diffusion optical path changing member configured to convert the laser light into the diffusion light and change an optical path. The output optical path does not include an optical path in which laser light emitted toward the diffusion optical path changing member goes straight at a light diffusion position according to the diffusion optical path changing member to go toward the light output unit.

    摘要： A light source device capable of contributing to an improvement in safety to laser beam is provided, even if a situation that a diffusion member does not exist in a traveling optical path of the laser beam in a normal state occurs. The light source device of the present invention includes a light source section (1) that emits laser beam (P), a diffusion member (8) that is provided in a traveling optical path of the laser beam (P) and transmits the laser beam (P) while diffusing the laser beam, a detection element (20) that detects whether the diffusion member (8) exists in the traveling optical path of the laser beam in a normal state by a physical characteristic of the diffusion member (8) and outputs a state detecting signal, and an abnormal state determiner (30a) that has a predetermined threshold to determine whether the diffusion member exists in the traveling optical path in a normal state and determines an abnormal state of the diffusion member (8) by comparing the state detecting signal with the threshold. The light source section (1) is controlled in a direction where an output of the laser beam (P) is reduced when the abnormal state is determined by the abnormal state determiner (30a).
