ABSTRACT:
It is desirable to be able to provide evenly illuminated, long lasting, relatively high power ultraviolet radiation for manufacturing processes such as sterilization and ink or adhesive curing. A generally rigid waveguide (2) having a slot (8) formed in one of its short sides (4) (or optionally one of its long sides (6)) may have an ultraviolet energizable elongate lamp (10) inserted therein. When the waveguide is coupled to a source of microwave energy, the slot radiates and the radiated energy is coupled almost exclusively into the lamp (10). With suitable choices of slot widths this provides even illumination with minimal microwave leakage.
