  • Publication number: 20190235372
    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.

  • Patent number: 10353282
    Abstract: The projection display apparatus includes a light source unit, a light deflector, a first light receiver, a second light receiver, and a calculator. The light deflector deflects at least part of incident light coming from the light source unit to a first optical path so as to produce a projection light, and deflects a remaining part of the incident light to a second optical path. The first light receiver receives the at least part of the incident light that has been reflected by the projection surface. The second light receiver receives the remaining part of the incident light. The calculator calculates a distance from the projection display apparatus to a projection surface based on light reception results obtained by the first light receiver receiving the at least part of the incident light and the second light receiver receiving the remaining part of the incident light.

  • 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.
