Abstract

A reflecting mirror (1) having its cross section of a parabolic shape is provided approximately in front of a filament (9) of a lamp bulb (7). A reflex reflecting portion (5) is provided between reflecting mirror (1) and a socket in which lamp bulb (7) inserted. Reflex reflecting portion (5) reflects back emitted light from filament (9), and then directs the reflected light forward through reflecting mirror (1).
