  • Publication number: 20240011618
    Abstract: 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.

  • Patent number: 11835201
    Abstract: 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.

  • Patent number: 11725801
    Abstract: 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.

  • Patent number: 11105489
    Abstract: An illumination lens includes an incident face (510), being provided in a recessed manner in a bottom apex part of the lens body (51), and receiving light from the light source (41); a reflection face (520) on the inner side of an outer periphery of the lens body (51), totally reflecting the light, having reached from the incident face (510); and an emission face (530) at the upper end of the lens body (51), emitting the light, having reached from the incident face (510) and the reflection face (520), to the outside, and the incident face (510) distributes the light, which could be directed toward the entire region of the reflection face (520), only in a predetermined range (521) within the reflection face, being adjacent to the upper end side portion, following the emission face (530), and being closer to the bottom apex part.
