  • Patent number: 10634979
    Abstract: A lighting apparatus is provided with a light source unit including laser diode elements, a collimating lens, and at least one optical element changing only a predetermined one-axis direction of a traveling direction of the substantially parallel light. When the substantially parallel light is incident on a first surface of the optical element, the optical element reflects the substantially parallel light by a second surface to change only the one-axis direction of the traveling direction of the substantially parallel light, and emits an inclined light flux inclined from the substantially parallel light. An aspect ratio of a screen configured by spot lights from the light source unit is changed to an aspect ratio on a cross section of a predetermined position in a traveling direction of the inclined light flux.

  • Publication number: 20190089889
    Abstract: A night vision imaging apparatus includes a light projecting section, a light amount controller, an imaging section, and a recording section. The light projecting section casts a near infrared ray as illumination light on an illumination area. The light amount controller controls an amount of the illumination light on each one of sub-areas forming the illumination area. The imaging section images the illumination area, and generates image data. The recording section records the image data generated by the imaging section. The light amount controller divides an image shown in the image data into a plurality of divided portions, and determines a light intensity of each one of the plurality of divided portion, and then controls an amount of the illumination light to be casted on a sub-area corresponding to each one of the plurality of divided portions among the sub-areas of the illumination area based on the determined light intensity.
