Per 2002 NFPA 13 (the sprinkler code) Table 8.3.2.5(c), 0-250 W light fixture requires a minimum distance of 6 inches from ordinary-temperature sprinklers, and 3 inches from intermediate-temperature sprinklers. Also, 250-499 W fixtures require a clearance of 12 and 6 inches respectively.

Any fixture within the spray pattern would have to be considered in the design by the engineer or certified installer to allow full coverage despite the obstruction.
