Abstract:
A headlamp disclosed includes: a laser diode for emitting a laser beam; a light emitting section including a fluorescent material which emits light in response to excitation light emitted from the laser diode; a light-transmitting heat conducting member which is provided so as to face a laser beam irradiation surface of the light emitting section and receive heat of the light emitting section; and an adhesive layer filling a gap between the heat conducting member and the laser beam irradiation surface. This arrangement improves efficiency of the heat conducting member in absorbing the heat of the light emitting section, and consequently cools the light emitting section efficiently.
