Patent number: 6824299Abstract: A marker lamp for a vehicle that has a tail lamp function and a stop lamp function including a bulb, light-emitting diodes and a reflector which are disposed in a lamp chamber defined by a lamp body and a front cover that covers the front portion of the lamp body. The bulb is positioned at the center of the reflector, the reflector is formed with a plurality of openings around the bulb and a primary reflective surface that reflects the light from the bulb substantially forward, and the light-emitting diodes are disposed so as to surround the bulb and face the front cover through the openings formed in the reflector. The tail lamp function is executed by lighting the bulb, and the stop lamp function is executed by lighting the light-emitting diodes.Type: GrantFiled: December 18, 2002Date of Patent: November 30, 2004Assignee: Koito Manufacturing Co., Ltd.Inventors: Fumihiko Mohri, Hiroki Fujinami, Hideyuki Aihara, Norihiro Nishitani

Patent number: 6543920Abstract: A vehicle headlamp includes right and left reflectors disposed in a lamp body and a ballast that allows a discharge bulb mounted in the reflector to continue a stable discharge. The pair of right and left reflectors is offset in the vertical direction. The right reflector is also offset in the fore-and-aft direction to be located behind the adjacent left reflector. The ballast is disposed to extend over enlarged spaces extending from below the right reflector. Thus, the center of gravity of the ballast is made close to the center of gravity of the headlamp excluding the ballast.Type: GrantFiled: December 6, 2001Date of Patent: April 8, 2003Assignee: Koito Manufacturing Co., Ltd.Inventors: Hiroki Fujinami, Norihiro Nishitani
