    • A light source device according to the present invention includes: a light source section; a light guide member provided at a position where the light guide member receives light emitted from the light source section, the light guide member having a tapered shape in which the light guide member gradually increases in width from its incident surface toward its emission surface, and an optical filter provided at a position where the optical filter receives light emitted from the light guide member, the optical filter reducing a spectrum having a predetermined waveband from the light. This makes it possible to provide a light source device which can control a radiation angle of light and which is downsized, and a pseudo-sunlight irradiation device including the light source device.
    • 根据本发明的光源装置包括:光源部; 导光构件,其设置在所述导光构件接收从所述光源部发射的光的位置处,所述导光构件具有锥形形状,所述导光构件的导光构件的入射面朝向其发射面逐渐增大;以及 设置在光滤波器接收从导光构件发出的光的位置处的光学滤波器,所述滤光器从光降低具有预定波段的光谱。 这使得可以提供一种可以控制光的辐射角并且其尺寸减小的光源装置,以及包括该光源装置的假日照射装置。
