Abstract

PURPOSE: To effectively utilize a luminous flux to form the desirable luminous intensity distribution pattern by installing a luminous intensity distribution forming means which reflects part of luminous flux advancing to the region unnecessary for the luminous intensity distribution pattern of the luminous flux emitted downward from a light source, and returns to the vicinity of a first focal point. CONSTITUTION: Part of luminous flux advancing to the region unnecessary for the luminous intensity distribution pattern, i.e., luminous fluxes d1 , d2 emitted downward from a light source 2 are reflected on the lower side reflecting surface 1b of an elliptic reflecting mirror 1, reflected with an auxiliary elliptic reflecting mirror 6 after passed through a second focal point F2, returned through an optical path same as the coming path, passed through the lower side reflecting surface 1b of the elliptic reflecting mirror 1 and a first focal point F1, reflected with an upper side reflecting surface 1a, passed through the lower half of the second focal point F2 and a condenser lens 3, then irradiated to the outside as parallel illumination luminous fluxes d1 ', d2 '. The luminous flux emitted from the light source 2 is effectively utilized to ensure sufficient illumination luminance, and the desirable luminous intensity distribution pattern is formed.
