1. A sun-tanning apparatus, comprising: a trough-shaped upwardly concave reflector;  a plurality of mutually parallel transversely spaced ultraviolet-radiating tubes mounted in said reflector;  a supporting surface transmissive to ultraviolet radiation for a person to be tanned by ultraviolet radiation from said tubes spanning said reflector above said tubes; and  a trough-shaped upwardly concave reflector;  a plurality of mutually parallel transversely spaced ultraviolet-radiating tubes mounted in said reflector;  a supporting surface transmissive to ultraviolet radiation for a person to be tanned by ultraviolet radiation from said tubes spanning said reflector above said tubes; and  a plurality of spacers between said tubes, braced upon said reflector and engaging said surface from below to support said surface upon said reflector at a plurality of locations.  a trough-shaped upwardly concave reflector;  a plurality of mutually parallel transversely spaced ultraviolet-radiating tubes mounted in said reflector;  a supporting surface transmissive to ultraviolet radiation for a person to be tanned by ultraviolet radiation from said tubes spanning said reflector above said tubes;  rows of spaced-apart spacers between said tubes, braced upon said reflector and engaging said surface from below to support said surface upon said reflector at a multiplicity of discrete points spaced apart over the length and breadth of said surface; and  adjusting means for each of said spacers selectively varying the distance from said reflector at which each of said spacers engages said surface from below. 2. The sun-tanning apparatus defined in claim 1 wherein said spacers are stand-off bolts having upper ends upon which said surface rests and lower ends secured to said reflector. 3. The sun-tanning apparatus defined in claim 2 wherein said stand-off bolts are arrayed in rows extending both longitudinally and tranversely of the apparatus. 4. The sun-tanning apparatus defined in claim 2 wherein four rows of said stand-off bolts are provided. 5. The sun-tanning apparatus defined in claim 20 wherein the stand-off bolts are staggered from row to row. 6. The sun-tanning apparatus defined in claim 2 wherein a respective attachment nut is secured to said reflector to receive each of said stand-off bolts and said stand-off bolts are threadedly engaged in the respective nuts. 7. The sun-tanning apparatus defined in claim defined in claim 6, further comprising a locknut threaded onto each stand-off bolt for locking same in the respective attachment nut. 8. A sun-tanning apparatus, comprising: 9. A sun-tanning apparatus, comprising:
