    • A light source unit includes a light emitting plate which has a plurality of segment areas and in which a luminescent material layer which emits light having a predetermined wavelength band by receiving excitation light and a transmissive portion which transmits light are formed on at least the plurality of segment areas, a primary light source for emitting excitation light on to the luminescent material, a secondary light source for emitting light having a wavelength band which differs from those of luminescent light emitted from the luminescent material layer and excitation light emitted from the primary light source, a light guiding optical system for guiding light emitted from the light emitting plate and light emitted from the secondary light source to the same optical path, and a light source control means for controlling the emission of light from the primary light source and the secondary light source.
    • 光源单元包括发光板,该发光板具有多个段区域,并且在至少多个区域上形成有通过接收激发光而发射具有预定波长带的光的发光材料层和透射光的透射部分 分段区域,用于将激发光发射到发光材料上的初级光源,用于发射具有与从发光材料层发射的发光光不同的波长带的光的二次光源和从主光源发射的激发光 用于将从发光板发射的光和从二次光源发射的光引导到相同光路的导光光学系统,以及用于控制来自主光源和次光的光的发射的光源控制装置 资源。
