  • Patent number: 11359790
    Abstract: An optical device (201) comprises a lens (205) having a light ingress surface (206) and a light egress surface (207). The light ingress surface comprises one or more V-shaped projections on a center area (208) of the light ingress surface and the light ingress surface is free from corners on areas (209) outside the center area. Each V-shaped projection is shaped so that a surface penetration takes place when a light beam arrives at a side surface of the V-shaped projection and a total internal reflection takes place when the light beam arrives at the other side surface of the V-shaped projection. Thus, obliquely arriving light beams emitted by edge areas of a light emitting surface (213) of a light source (202) are mixed better with light beams emitted by other areas of the light emitting surface. Therefore, undesired color variations within a light distribution pattern are reduced.

  • Patent number: 11263428
    Abstract: Introduced here are multi-channel light sources able to produce a broad range of electromagnetic radiation. A multi-channel light source (also referred to as a “multi-channel emitter”) can be designed to produce visible light and/or non-visible light. For example, some embodiments of the multi-channel light source include illuminant(s) capable of emitting electromagnetic radiation within the visible range and illuminant(s) capable of emitting electromagnetic radiation in a non-visible range, such as the ultraviolet range or infrared range. By capturing images in conjunction with the visible and non-visible light, additional information on the ambient scene can be gleaned which may be useful, for example, during post-processing.
