Abstract
A headlamp device can include a headlight bulb and position light bulbs. In addition, the headlamp device can have an intermediate member between the lens and a reflector by which light from the headlight bulb is reflected. The intermediate member is provided with cutouts through which a gas present on the lens side relative to the intermediate member can flow to the base member side relative to the intermediate member. Thus convection of the gas takes place easily, whereby release of heat from within the internal space is accelerated.
Claims13
A headlamp device, comprising:
- a base member configured to receive a headlight light source and a position-light light source;
- a lens mounted to a front portion of said base member;
- a reflector which is disposed in an internal space defined by said base member and said lens and which is configured to reflect light emitted by the headlight light source;
- and
- an intermediate member which covers said base member at least in surroundings of said reflector in front view,
- wherein said intermediate member includes a cutout which is configured to permit a gas present on a lens side relative to said intermediate member to flow therethrough to a base member side relative to said intermediate member.
A headlamp device, comprising:
- base means for receiving a headlight light source and a position-light light source thereon;
- lens means for diffracting light, said lens means mounted to a front portion of said base means;
- reflector means for reflecting light emitted by the headlight light source, said reflector means being disposed in an internal space defined by said base means and said lens means;
- cover means for covering said base means in an area of said reflector means in front view;
- wherein said cover means includes a cutout for permitting a gas present on a lens means side relative to said cover means to flow therethrough to a base means side relative to said cover means.
A method of cooling a headlamp device, comprising:
- providing a headlight source and a position-light source on a base;
- providing a lens on a front portion of the base;
- providing a reflector in an internal space defined by the base and the lens;
- providing a cover for covering the base in an area of the reflector in front view;
- and
- permitting a gas present on a lens side relative to the cover to flow through a cutout to a base-side relative to the cover.
