1. A fingernail light system for curing photo-polymerizable plastics on fingernails, having a housing (1) with a bottom plate (7) in which housing there is provided a support body (4), having indentations (18) on its outer contour, for positioning fingers (20-24) of a hand to be irradiated, and having at least one irradiation lamp (14), which at least partially surrounds the support body in a spaced-apart manner in an irradiation position, the support body being accessible in the irradiation position via an opening (10) formed in the housing (1),  and wherein,  the support body (4) has a generally convex outer contour, defining a central palm-support surface with said indentations radiating therefrom, said indentations defining channels (18) that extend substantially in the direction of a longitudinal axis (3) of the support body (4), and positively position fingers placed therein, and the axis (3) of the support body (4) forms an angle (30) in the range from 0.degree. to 90.degree. with the direction (31) orthogonal to the bottom plate (7).  wherein the channels (18) of the support body (4) are located symmetrically with respect to a first plane (19) extending through the axis (3) of the support body (4) and in the direction of the arm (16) of a hand (5) to be placed on the support body (4).  wherein the channel (18) associated with the middle finger (20) extends in the vicinity of the first plane (19).  wherein the support body (4) has one channel (18) each for the little finger (23) of the left and right hand, which channels extends approximately along a second plane extending through the axis (3) of the support body (4) and vertically to the first plane (19).  wherein the channels (18) for the little fingers (23) are on a raised portion of the support body, in such a way that the finger nails (15) of the little fingers (23) are positioned outside the shadow of the ring finger.  wherein that two channels (18) are provided for the thumbs (24), two channels (18) are provided for the ring fingers (21) and two channels (18) are provided for the index fingers (22).  wherein the channels (18) are distributed about the circumference of the support body (4) over an angular range extending approximately 300.degree. to 320.degree. about said circumference.  wherein the support body (4) is located movable in the direction of its axis (3) into and out of the housing (1).  wherein the support body (4) is located such that it is displaceable counter to the force of at least one spring (8).  wherein the rim of the housing opening (10) merges with a support (17), which is located on the housing (1) opposite the channel (18) for the index finger (22) of the support body (4).  wherein the housing opening (10) is at least partly closeable by means of a hinged glare protection hood (33).  wherein the support body (4), at least in the region of the channels (18), has positioning means in the form of stops (34) against which the fingertips of the hand (5) to be irradiated rest.  wherein the stops (34) are located at the lower rim, oriented toward the bottom plate (7), of the support body (4).  wherein an end switch (26) is provided, which is actuated for operation of the system upon introduction of the support body (4) into the housing (1).  wherein the at least one irradiation lamp (12) approximately describes a circle or a circular segment.  wherein the circle or the circular segment is approximated by means of a plurality of elongated irradiation lamps (12) having a straight lamp axis (14). 2. A fingernail light system according to claim 1, wherein the axis (3) of the support body (4) forms an angle (30) in the range from 0.degree. to 60.degree. with the direction (31) orthogonal to the bottom plate (7). 3. A fingernail light system according to claim 1, 4. A fingernail light system according to claim 3, 5. A fingernail light system according to claim 3, 6. A fingernail light system according to claim 1, 7. A fingernail light system according to claim 1, 8. A fingernail light system according to claim 7, 9. A fingernail light system according to claim 1, 10. A fingernail light system according to claim 9, 11. A fingernail light system according to claim 9, 12. A fingernail light system according to claim 1, 13. A fingernail light system according to claim 1, 14. A fingernail light system according to claim 13, 15. A fingernail light system according to claim 9, 16. A fingernail light system according to claim 1, 17. A fingernail light system according to claim 16,
