Abstract
A lighting apparatus (10) comprises a light engine (12) producing ultra violet radiation. An enclosure (14) surrounds a radiation generating area of the light engine (12) to encompass the radiation. At least one wall (28) of the enclosure (14) is substantially reflective of the ultraviolet radiation. The enclosure (14) includes a replaceable top portion (30) which includes a phosphor portion (32). The phosphor portion (32) is spaced from the radiation generating area of the light engine (12) by a height of the enclosure (14).

16. A lighting system comprising:
-
a light engine having a direction of primary radiation emission and including;
a PC board, a plurality of UV LEDs disposed on the PC board, and a heat sink disposed on a side of the PC board opposed to the LEDs; and
an enclosure surrounding the direction of radiation emission and including;
at least one portion which substantially reflects UV radiation, and a phosphor containing portion generally opposite and spaced from the light engine, the phosphor containing portion including;
a visible light reflecting layer on a first side of the phosphor facing the light engine and a UV light reflecting layer on a second side of the phosphor away from the light engine.
