a phosphor layer (3) being arranged at the upper face of the carrier member (2), whereby the phosphor layer (3) comprises at least one phosphor zone (R; G; Y); a reflective zone (33) being arranged adjacent to the at least one phosphor zone (R; G; Y); an optical transmitting member (4) having a first end face (7) and a second end face (9), the optical transmitting member (4) being arranged at the top portion of the phosphor layer (3) and the reflective zone (33), whereby wherein the first end face (7) of the optical transmitting member (4) covers at least a subarea (8) of each of the at least one phosphor zone (R; G; Y) and the reflective zone (33). ## Claims ### Claim 1 A phosphor device comprising: a carrier member having upper and lower faces; a phosphor layer being arranged at the upper face of the carrier member, whereby the phosphor layer comprises at least one phosphor zone; a reflective zone being arranged adjacent to the at least one phosphor zone; an optical transmitting member having a first end face and a second end face, the optical transmitting member being arranged at the top portion of the phosphor layer and the reflective zone, wherein the first end face of the optical transmitting member covers at least a subarea of each of the at least one phosphor zone and the reflective zone. ### Claim 2 (depends on 1) The phosphor device according to claim 1, wherein the at least one phosphor zone comprises a phosphor component or a phosphor mixture. ### Claim 3 (depends on 2) The phosphor device according to claim 2, wherein the phosphor component is any member of the following group: a phosphor for emitting red light, a phosphor for emitting green light, a phosphor for emitting yellow light. ### Claim 4 (depends on 2) The phosphor device according to claim 2, wherein the phosphor mixture is suitable for emitting white light. ### Claim 5 (depends on 1) The phosphor device according to claim 1, comprising two or more phosphor zones, wherein the phosphor zones are separated from each other by division bars. ### Claim 6 (depends on 5) The phosphor device according to claim 5, wherein the phosphor zones are individually embedded into the carrier member. ### Claim 7 (depends on 1) The phosphor device according to claim 1, wherein the phosphor device is configured to enable relative lateral movement between the first end face of the optical transmitting member and the at least one phosphor zone and the reflective zone. ### Claim 8 (depends on 7) The phosphor device according to claim 7, wherein the at least one phosphor zone and the reflective zone are configured such that the proportions of the subareas of the zones covered by the first end face of the optical transmitting member change in directions of the relative movement. ### Claim 9 (depends on 1) The phosphor device according to claim 1, wherein the optical transmitting member is elongated and has a polygonal cross section. ### Claim 10 (depends on 1) A lighting apparatus comprising: a phosphor device according to claim 1; an exciting light source for emitting exciting light; wherein the phosphor device and the exciting light source are arranged such that the exciting light is enabled to enter the phosphor device through the second end face of the optical transmitting member. ### Claim 11 (depends on 10) The lighting apparatus according to claim 10, wherein the exciting light source comprises a laser light source. ### Claim 12 (depends on 10) A method of operation of a lighting apparatus according to claim 10 comprising the following steps: positioning the optical transmitting member such that at least subareas of the at least one phosphor zone of the phosphor layer and the adjacent reflective zone are covered by the first end face of the optical transmitting member; and guiding the exciting light for entering the optical transmitting member through its second end face and for impinging on the phosphor layer and the reflective zone through its first end face. ### Claim 13 (depends on 12) The method according to claim 12, further comprising the steps of collecting and mixing the light, wavelength-converted by the area of the phosphor layer irradiated by the exciting light, and the exciting light directly reflected by the reflective zone with the optical transmitting member. ### Claim 14 (depends on 13) The method according to claim 13, further comprising the step of moving the optical transmitting member over the surface of the phosphor layer and the adjacent reflective zone for adjusting the properties of the mixed light, thereby covering various subareas of the phosphor zones of the phosphor layer and the reflective zone, resulting in various proportions of irradiated subareas of the phosphor zones and the reflective zone, respectively. ### Claim 15 (depends on 12) The method according to claim 12, further comprising the steps of sensing the resulting light colour or corrected colour temperature and controlling and adjusting the relative position of the optical transmitting member if necessary to achieve a target value.
