Patent number: 10634302Abstract: A vehicle lamp includes a light source, and a reflector which reflects light emitted from the light source to form a low-beam light distribution pattern. The light source includes first and second light emitting elements. The reflector includes a first reflecting surface which reflects light emitted from the first light emitting element to form a first light distribution pattern configuring a part of the low-beam light distribution pattern, and a second reflecting surface which reflects light emitted from the second light emitting element to form a second light distribution pattern for enhancing brightness of a lower vicinity region of a cut-off line on an oncoming vehicle lane side. The second reflecting surface is arranged in a surface normal direction of a light emitting surface of the second light emitting element on a front side of the first reflecting surface.Type: GrantFiled: June 6, 2018Date of Patent: April 28, 2020Assignee: KOITO MANUFACTURING CO., LTD.Inventor: Ippei Yamamoto
