Patent number: 12013093Abstract: 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: GrantFiled: December 2, 2021Date of Patent: June 18, 2024Assignee: KOITO MANUFACTURING CO., LTD.Inventors: Teppei Muramatsu, Yuta Ugajin

Patent number: 9222638Abstract: Provided is a vehicular headlamp which is capable of enhancing visibility while suppressing glare by forming a dark portion in a portion of a light distribution pattern and suppressing the vicinity of the formed dark portion from becoming a blue series color. The vehicular headlamp includes a light-emitting element, a projection lens, a reflector, a beam shaper, a first shaper disposed between the light-emitting element and a cut-off line forming portion and configured to shield a part of the light reflected from the reflector to form a dark portion in a portion of a low beam light distribution pattern, and a second shaper portion disposed between the cut-off line forming portion and the projection lens and configured to shield a part of the light incident to the lower side of an optical axis of the projection lens.Type: GrantFiled: June 14, 2013Date of Patent: December 29, 2015Assignee: Koito Manufacturing Co., Ltd.Inventors: Yusuke Nakada, Yuta Ugajin
