Patent number: 11940116Abstract: To improve the sense of connection between a fixed-side lamp unit and a movable-side lamp unit. A vehicle lamp includes; a fixed-side unit, and a movable-side unit, the fixed-side unit has: a first light source; a first light guide body; and a first outer lens having a first front surface part, and a first leg part, the movable-side unit has: a second light source; and a second light guide body; and a second outer lens having a second front surface part, and a second leg part, the second leg part has a light control surface, and the light control surface performs control such that light emitted from at least one of the first light source and the second light source and incident on the light control surface passes through inside of the second leg part and is emitted from a front surface side of the second leg part.Type: GrantFiled: May 26, 2021Date of Patent: March 26, 2024Assignee: Ichikoh Industries, Ltd.Inventor: Koji Nishihata

Publication number: 20170108191Abstract: A vehicular light guide member according to the present invention is constituted from two light guide members. Each of the overlapping surfaces of each of the two light guide members is slanted with respect to the light-guiding direction of the two light guide members. The overlapping surface of the upper side light guide member covers the overlapping surface of the lower side light guide member from the emission direction side where the emission light from the two light guide members is emitted outward. As a result, the vehicular light guide member according to the present invention has little light leakage, can transmit light efficiently, can alleviate the issue of punctate lights, and can have an improved appearance.Type: ApplicationFiled: April 10, 2015Publication date: April 20, 2017Applicant: ICHIKOH INDUSTRIES, LTD.Inventor: Koji NISHIHATA

Patent number: 7883250Abstract: In existing lamp unit for vehicles, the light from the semiconductor light source can not be effectively used. In the present invention, a planar reflect surface (7) is arranged between the projection lens (6) and its focus (FL1) in such a way that the planar reflect surface (7) intersects the light axis (Z1-Z1) of the projection lens (6); a light shutout member (8) is arranged between the semiconductor light source (4) and the projection lens (6); the light shutout member (8) is provided with supplemental reflect surfaces (17-20) reflecting the light (L3) from the semiconductor light source (4) toward the shade (5). As a result, the light (L3) from the semiconductor light source (4) can be effectively used.Type: GrantFiled: April 24, 2008Date of Patent: February 8, 2011Assignee: Ichikoh Industries, Ltd.Inventor: Koji Nishihata

Patent number: 7832912Abstract: In existing lamp unit for vehicles, the light from the semiconductor light source can not be effectively used. In the present invention, a shade (5) is arranged between the second focus (F2) of a first reflect surface (9) and a semiconductor light source (4), for cutting off a portion of the reflected light (L4) emitting from the semiconductor light source (4) and reflected by the first reflect surface (9), and using the remaining reflected light (L4) to form a predetermined distributed light pattern (P) having the cutoff lines (CL); a light shutout member (8) is provided with the fourth part (20) of the supplemental reflect surface for reflecting the light (L3) from the semiconductor light source (4) toward the shade (5); a through hole (24) is arranged on the shade (5) for the reflected light (L17) from the fourth part (20) of the supplemental reflect surface illuminating therethrough toward the planar reflect surface (7).Type: GrantFiled: April 24, 2008Date of Patent: November 16, 2010Assignee: Ichikoh Industries, Ltd.Inventor: Koji Nishihata
