Publication number: 20240019094Abstract: A light unit is configured in such a manner that a light guide is placed between a light source and a projection lens, and includes a first exit surface for emitting light for a low-beam light distribution pattern and a second exit surface for emitting light for an additional light distribution pattern that is added to form a high-beam light distribution pattern. The light guide is configured to be provided with a mirror surface portion on a connection surface extending toward the back of the unit from a lower edge of the first exit surface to an upper edge of the second exit surface. As a result, light from a light-emitting element that has been emitted through the second exit surface and reached the connection surface is reflected by the mirror surface portion to be used as the light for forming the additional light distribution pattern.Type: ApplicationFiled: December 2, 2021Publication date: January 18, 2024Inventors: Teppei MURAMATSU, Yuta UGAJIN

Patent number: 11092308Abstract: A light emitting element, a reflector, a projection lens, and a movable shade are arranged in a lamp chamber. As the movable shade is erected, a low beam is formed. As the movable shade is tilted, a travelling beam is formed. The reflector and a sub reflector are integrally formed. The movable reflector reflects the reflected light reflected by the sub reflector toward the projection lens. The sub reflector is positioned in a range of an outer shape of the projection lens.Type: GrantFiled: September 15, 2017Date of Patent: August 17, 2021Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Akinori Matsumoto, Kazuma Mochizuki, Yoshiyuki Nakanishi, Teppei Muramatsu
