Vehicle headlamp and illuminating device

摘要

A headlamp1includes a laser diode3that emits a laser beam, a light emitting part7that emits light upon receiving the laser beam emitted from the laser diode3, and a reflection mirror8that reflects the light emitted from the light emitting part7. According to the headlamp1, the light emitting part7has a luminance greater than 25 cd/mm2, and an area size of an aperture plane8aperpendicular to a direction in which an incoherent light travels outward from the headlamp1is less than 2000 mm2.
