HEADLAMP DEVICE FOR A VEHICLE

A headlamp device includes an upper lens (41), a lower lens assembly (42), a reflector (5), a blocking board (6) and a light emitting unit (7) . The light emitting unit (7) includes a first light source (71) and a second light source (72) that are each operable to switch between an on-state and an off-state. When the first light source (71) is in the on-state and when the second light source (72) is in the off-state, low beam light rays are generated by cooperation of the upper lens (41), the reflector (5), the blocking board (6) and the first light source (71). When the second light source (72) and the first light source (71) are in the on-state, high beam light rays are generated by cooperation of the upper lens (41), the lower lens assembly (42), the reflector (5), the blocking board (6) and the light emitting unit (7).
