Publication number: 20240011618Abstract: A vehicle side light that can decrease the number of components to reduce the cost, that does not produce a dark portion not easily visible, and that can more easily perform efficient light distribution control only in necessary directions with a simple configuration. In a vehicle side light (10) that is provided on a vehicle side surface, and that is constructed by supporting, in a light body (11), a light source (20) and a lens (30) for distributing light from the light source (20), the light source (20) is constructed by mounting a plurality of LEDs (22) on a surface of a single substrate (21), and the lens (30) is arranged in a front direction of the light source (20), and is capable of distributing light of any of the plurality of LEDs (22) to both sides of the vehicle side surface in addition to the front direction perpendicular to the vehicle side surface.Type: ApplicationFiled: July 5, 2021Publication date: January 11, 2024Inventors: Shuhei KOJIMA, Kohei NOGAMI, Youmei KAMINAGA, Akira SAITO, Yasuyo KOJIMA

Patent number: 11835201Abstract: An optical lens (10) capable of facilitating efficient light distribution control with a simple configuration is provided. It comprises a plurality of light distribution control parts (11) continuing in a bilateral direction such that each of the light distribution control parts corresponds to each column of LEDs (22), the light distribution control parts defining optical paths of light from the LEDs (22) on a column basis, one light distribution control part (11) discharges light entering from the LEDs (22) in a column corresponding thereto in one direction of the bilateral direction that intersects the optical axes, and a further light distribution control part (11) discharges light entering from the LEDs (22) in a column corresponding thereto in a further direction of the bilateral direction that intersects the optical axes.Type: GrantFiled: June 8, 2020Date of Patent: December 5, 2023Assignee: KOITO ELECTRIC INDUSTRIES, LTD.Inventors: Yasuyo Kojima, Youmei Kaminaga

Patent number: 11725801Abstract: An optical lens capable of facilitating efficient light distribution control with a simple configuration includes a plurality of light distribution control parts arranged in a bilateral direction such that each of the light distribution control parts corresponds to each column of LEDs. The light distribution control parts define optical paths of light from the LEDs. The optical paths are sequentially shortened from one end side to the other end side in the bilateral direction. The light distribution control parts guide the light in a direction that intersects optical axes of the LEDs.Type: GrantFiled: June 8, 2020Date of Patent: August 15, 2023Assignee: KOITO ELECTRIC INDUSTRIES, LTD.Inventors: Yasuyo Kojima, Youmei Kaminaga
