A halogen infrared lamp (100) having an infrared reflective coating (118)
along with a totally reflecting coating (120) on ends of an ellipsoidal
portion of the envelope. The totally reflecting coating reflects the infrared radiation
escaping at acute angles and directs the infrared radiation towards the filament
to increase the temperature of the filament and thus increase the efficacy of the
lamp. The totally reflecting coating may also extend to portions of tubular members
extending from the ellipsoidal portion of the envelope.
