ABSTRACT:
A shatter glass guard and venting effect design for a fixture of a luminaire adapted to provide adequate shatter guard protection for the purpose of preventing glass from a broken lamp from being released from the fixture. An annular ring of perforated material is attached to an open end of a reflector. A lens is attached to the outside surface of the annular ring and is dimensioned to expose a portion of the perforated material to allow for venting of heat from within the fixture. The lens and lamp can be installed or removed from the fixture after installation without access from the top of the light housing. The lens when mounted becomes integral with the reflector and moves with the reflector should the reflector need to be adjusted or tilted for aiming. The lens and annular ring combination provides adequate shatter guard protection and venting of the fixture.
