A phosphor device (1) comprises a carrier member (2) and a phosphor layer (3) as well as a reflective zone (33) being arranged at the upper face of the carrier member (2). The phosphor layer (3) comprises at least one phos-phor zones (R, G). The first end face (7) of the optical transmitting member (4) covers at least a subarea (8) of each zone (R,G,33). The exciting light, entering the op-tical transmitting member (4) through its second end face (9), impinges on the phosphor layer (3) and the reflec-tive zone (33). A fraction of the impinging light is re-flected after being wavelength-converted by the phos-phor(s) of the phosphor layer. Another fraction of the impinging light is directly reflected by the reflective zone (33). Both fractions of the light are collected and mixed by the optical transmitting member (4). The proper-ties of the wavelength-converted mixed light may be ad-justed by adjusting the proportions of the subareas (8) of the zones (R,G,33) irradiated by the exciting light.本發明係關於螢光體裝置及包含此裝置之發光設備。螢光體裝置(1)包括：載體構件(2)及配置在載體構件(2)之上面的螢光體層(3)及反射區(33)。螢光體層(3)包括至少一個螢光體區(R,G)。透光構件(4)之第1端面(7)覆蓋每一區(R,G,33)之至少一副區(8)。通過第2端面(9)進入透光構件(4)的激發光照射螢光體層(3)及反射區(33)上。照射光之一部分在藉螢光體層之螢光體做波長轉換之後被反射。照射光之另一部分被反射區(33)直接反射。此兩部分的光被透光構件(4)集光及混合。做波長轉換後的混合光之性質可藉調整被激發光所照射的螢光體區(R,G,33)之副區(8)的比例而被調整。
