Abstract

The invention provides a headlamp device, which obviates fogging on a lens by accelerate releasing of heat from within an internal space of the headlamp device. The headlamp device (10) includes a headlight bulb (106) and position light bulbs (108). In addition, the headlamp device (10) has an intermediate member (130) between the lens (102) and a reflector (122) by which light from the headlight bulb (106) is reflected. The intermediate member (130) is provided with cutouts (144) through which a gas present on the lens (102) side relative to the intermediate member (130) can flow to the base member (100) side relative to the intermediate member (130). Thus convection of the gas takes place easily, whereby release of heat from within the internal space (114) is accelerated.

Description

technical field [0001] The present invention relates to a headlamp device having a light source for a headlight and a light source for a position lamp. Background technique [0002] Patent Document 1 discloses a headlamp structure (device) including a headlight bulb (light source for headlight) and a position marker bulb (light source for position marker) in one unit. In this headlamp device, a position marker bulb is arranged obliquely above the headlight bulb in the vehicle width direction, and reflectors (vertical wall portions and upper wall surfaces) are provided in front and rear of the position marker bulb. The reflector reflects the light emitted from the position marker light bulb, and irradiates a predetermined amount of light to the outside of the headlight device as a position light. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2009-238412 [0004] However, the headlight device generates heat as the headlight bulbs and the position marker bulbs emi...
