Abstract
A vehicle headlamp includes: a light-emitting module; a control circuit section for controlling a lighting of the light-emitting module; and a reflector including a reflecting face configured to reflect and collect light emitted from the light-emitting module. The control circuit section includes an opposing portion that is opposed to the reflecting face. The opposing portion is disposed at a position away from an optical path of light to be collected by the reflector.
Claims3
A vehicle headlamp comprising:
- a support board;
- a light-emitting module supported on the support board;
- a control circuit section supported on the support board and configured to control a lighting of the light-emitting module;
- and
- a reflector including a reflecting face configured to reflect and collect the light emitted from the light-emitting module,
- wherein the control circuit section includes, on at least a part of the control circuit section, an opposing portion that is opposed to the reflecting face, and the support board is configured to support the light-emitting module and the control circuit section so that the opposing portion is disposed at a position away from an optical path of light to be collected by the reflector,
- wherein a height of the lowest portion of a light-emitting section of the light-emitting module from a support face of the support board is greater than a height of the highest portion of the opposing portion from the support face.
