摘要： In a projector-type headlight in which a light-emitting face of an LED 1 is placed perpendicular to an optical axis so that light emitted by the LED 1 is projected ahead of a vehicle through a convex lens 2, the light-emitting face is placed upward from the optical axis of the headlight, and a lower edge side 1a of the light-emitting face is formed into a linear shape and is placed on the optical axis, and a reflection face 3a is placed in a plane formed by the optical axis and the linear-shape edge side 1a of the LED 1 to thereby combine direct light emitted by the LED 1 and reflection light reflected on the reflection face 3a, so that an intensity of light emitted in a direction normal to the light-emitting face from the edge side 1a is enhanced.
