ABSTRACT:
Disclosed herein is a halogen lamp unit comprising a tubular halogen lamp having at its both ends sealed portions hermetically enclosing their respective conductive members. The halogen lamp is supported by holders at its tubular outer wall portions of the envelope adjacent to the sealed end portions without base shells which cover the sealed portions. The holders are cooled by a water-cooling system. The sealed end portions of the lamp are kept in a bare state, thereby avoiding the degradation of the conductive members due to the oxidation thereof. The sealed end portions may be exposed in air-paths to the cooling wind flowing along the tubular halogen lamp.
