Vehicle headlamp device |
摘要 |
A vehicle headlamp device is designed to provide the feeling that sufficient light quantity exists in the high beam (H-beam) mode despite the use of a single discharge light source. The headlamp can be produced at low cost and by simple construction without the need for installing an auxiliary reflective part on the reflective member. The vehicle headlamp device can include a discharge lamp light source, a switching device for switching between the high beam and low beam, and a lighting device which supplies electric power to the discharge lamp. The lighting device can be controlled such that the electric power supplied to the discharge lamp is increased only when the beam is switched to the H-beam mode by the switching device.
