  • Lamp device for vehicle
    Patent number: 6824302
    Abstract: Due to an effect of a solenoid of a moving mechanism, when a valve and a shutter are positioned at a first position, a light source is positioned at a first light source position and a shutter is in a state of closing a window. A lighting luminous flux from a light source is reflected by a reflector so as to be irradiated as a first light distribution pattern. Thus, a part of the lighting luminous flux is introduced to the reflector from the open window. Therefore, it is possible to effectively utilize the lighting luminous flux emitted from one valve in correspondence to a light distribution pattern.
    Type: Grant

  • Light source bulb of lighting device for vehicle
    Patent number: 6585401
    Abstract: A sliding contact is formed by a first terminal 40 fixed to a side of a lamp base flange 2 and a second terminal 41 fixed to a side of a slider 7. Accordingly, it is possible to supply an electric current to a glass tube 9 without bending a harness 3. Therefore, a harness 3 is not deteriorated, and a resistance at a time of sliding the glass tube 9 is not increased.
