1. A method for repairing a fiber-plastic composite of a rotor blade, the method comprising: applying a fiber-matrix composite comprising a UV-curable matrix material and a fiber material onto a local working area of the rotor blade, wherein applying the fiber-matrix composite comprises removing a double-layered supporting film located beneath the fiber-matrix composite as the fiber-matrix composite is being applied onto the local working area; andafter applying the fiber-matrix composite, removing a UV protection layer located over the fiber-matrix composite;in a light proof manner, attaching a casing of a UV lamp to the rotor blade at the local working area, wherein the casing includes a mold rim and is covered with a reflective layer; andusing the UV lamp, curing the matrix material using UV radiation. 2. The method according to claim 1, wherein: the fiber-matrix composite is a prepreg, fiber-matrix semifinished product; orapplying the fiber-matrix composite comprises applying a dry fiber material and introducing the UV-curable matrix material into the fiber material. 3. The method according to claim 1, wherein the matrix material is a UV-curable resin. 4. The method according to claim 1, wherein curing the matrix material using UV radiation occurs for less than 30 minutes. 5. The method according to claim 1, wherein the rotor blade comprising the fiber-plastic composite is mounted to a wind power installation while the steps of the method are being performed. 6. The method according to claim 1, wherein the rotor blade comprising the fiber-plastic composite is present as a single component while the steps of the method are being performed. 7. The method according to claim 1, wherein the fiber-plastic composite of the rotor blade includes a series of resin-impregnated laminate composite layers that are applied on a primary layer, and one or more cover layers are applied to the resin-impregnated laminate composite layers, wherein the method further comprises preparing the local working area by removing the one or more cover layers and at least some of the series of resin-impregnated laminate composite layers. 8. A semifinished product adapted to be used in the method of claim 1, wherein the semifinished product includes a fiber-matrix composite comprising a UV-curable matrix material and a fiber material, a double-layered supporting film located on a first side of the fiber-matrix composite, and a UV protection layer on a second side of the fiber-matrix composite. 9. A semifinished product in form of a composite structure, the semifinished product comprising: a double-layered supporting film;a UV protection layer; anda fiber-matrix composite comprising a UV-curable matrix material and a fiber material, wherein the fiber-matrix composite is arranged between the supporting film and the UV protection layer, wherein the semifinished product is for repairing a rotor blade of a wind power installation, wherein the fiber material is provided in a composite structure on the supporting film, wherein the supporting film is removed when the fiber-matrix composite is applied onto a local working area of the rotor blade, wherein after applying the fiber-matrix composite to the working area of the rotor blade, the UV protection is configured to be removed. 10. A UV lamp for curing a UV-curable matrix material at a rotor blade comprising: a source of UV light in a casing, wherein the casing is attachable, in a lightproof manner, to a local working area of the rotor blade, wherein the casing includes a mold rim and is covered with a reflective layer. 11. The UV lamp according to claim 10, wherein the casing includes at least one of the following: a flat attachment section that is defined by a casing rim;an arched attachment section that is defined by a casing rim; anda flexed multiplex attachment section that is defined by a casing rim. 12. The UV lamp according to claim 11, wherein the casing's flat attachment section includes additional casing parts that can be modularly mounted to a casing part comprising the source of UV light, wherein the additional casing parts include a flat, arched, or flexed attachment section. 13. The method according to claim 3, wherein the UV-curable resin is an acrylic resin or a vinyl ester resin. 14. The method according to claim 1, wherein: the fiber-matrix composite is provided with a UV protection layer on top of the fiber-matrix composite prior to applying the fiber-matrix composite;applying the fiber-matrix composite comprises applying a dry fiber material and introducing the UV-curable matrix material into the fiber material; andafter introducing the UV-curable matrix material into the fiber material, the UV protection is removed.
