射と直射フレネルカツト部の通過とによつて平行
光線に変えられ、前記放物反射面と前記直射フレ
ネルカツト部とに到達する光の領域の間に非有効
光領域が存在する灯火器構造において、前記非有
効光が通過する範囲に、バルブフイラメントを中

とを特徴とする灯火器構造。 A region of light in which the light emitted from the bulb is changed into parallel rays by reflection on the parabolic reflecting surface and passing through the direct Fresnel cut section, and reaches the parabolic reflecting surface and the direct Fresnel cut section. In a lamp structure in which an ineffective light region exists between the two, a spherical reflector having a bulb filament as its center is disposed in an area through which the ineffective light passes, and the ineffective light is directed to the parabolic reflecting surface. A lamp structure characterized in that it is configured to reflect light.
