摘要：PURPOSE:To effectively utilize the light from a light source with no futility and improve radiation efficiency by integrally providing a translucent cylindrical ction connected to the opening end ction of a reflecting mirror and surrounding the cond focal point on the outer periphery ction of a convex lens arranged in front of the cond focal point where the light reflected by the reflecting mirror is collected. CONSTITUTION:A projector lamp 11 has a reflecting mirror 12 with an elliptical cross ction opened at the front end, and the reflecting mirror 12 has the first and cond focal points f1, f2 on one optical axis passing the center. The filament 14 of a halogen lamp 13 fitted at the rear end ction of the reflecting mirror 12 is located at the first focal point f1, and the focal point f3 of a convex lens 15 arranged in front of the reflecting mirror 12 coincides with the cond focal point f2 where the light reflected by the reflecting mirror 12 is collected, and the light collected at the cond focal point f2 is projected forward by the convex lens 15. A translucent cylindrical ction 16 extended toward the front end opening ction 12a of the reflecting mirror 12 is integrally formed on the outer periphery ction of the convex lens 15, and the incident light into an inner periphery face 17b is refracted forward and radiated as the parallel light nt forward from the outer periphery face 17a of the cylindrical ction 16.
