Abstract
A lamp assembly having a reflector holding a lamp element, or burner. A reflector extension is designed to mate to the reflector. The reflector extension has a first open end toward the reflector. The first open end typically is in contact with the reflector to form a seal around the perimeter preventing glass shards from escaping between the reflector and reflector extension. The second end of the reflector extension also is open to allow the light from the arc to exit the reflector extension. A transparent plate placed across this second open end prevents glass from leaving the reflector extension. The transparent plate typically is glass, and may have an antireflective coating applied to the plate to limit the light reflected by the plate. Ventilation ports in the reflector extension allow cooling airflow into the cavity around the burner.
