Abstract: The light source includes first to eighth light sources configured to emit first to eighth lights, respectively. The first light has a first peak wavelength, the second light has a second peak wavelength, the third light has a third peak wavelength, and the fourth light has the second peak wavelength. The fifth light has the third wavelength, the sixth light has the second wavelength, the seventh light has the first wavelength, and the eighth light has the second wavelength. The first and fifth lights pass through a first optical member. The second and sixth lights pass through a second optical member. The third and seventh lights are reflected by the second optical member. The fourth and eighth lights are reflected by the first optical member.

Abstract: A light emitting module includes: a light source; and an optical member configured to control a distribution of light emitted from the light source. The optical member comprises an incident face on which the light from the light source is incident, and an output face through which the light incident on the incident face exits. In a plan view: the optical member is shaped to have a long axis and a short axis orthogonal to the long axis, and a central axis of the optical member passes through a center of the light source, a center of the incident face, and a center of the output face, while being orthogonal to a long axis direction parallel to the long axis and a short axis direction parallel to the short axis.

Abstract: An illumination device includes: a laser light source; a cylindrical body disposed such that light emitted from the laser light source enters the cylindrical body at a first end portion side of the cylindrical body and passes through the cylindrical body; a reflector disposed so as to reflect light passing through the cylindrical body; and a ring assembly comprising a ring-shaped inner circumferential surface configured to reflect and propagate light from the reflector. The reflector includes: a first reflecting surface configured to reflect a first portion of light emitted from the laser light source, and a second reflecting surface configured to reflect a second portion of light emitted from the laser light source. The ring assembly further includes a fluorescent surface adapted to emit fluorescence by light reflected and propagated at the inner circumferential surface.

Abstract: An image display device includes: a first display device configured to display a first image; an imaging optical system including: an input element configured to receive light emitted from the first display device, and an output element configured to receive light traveling via the input element and to emit light to form a real image corresponding to the first image; an optical member configured to reflect light emitted from the imaging optical system; and a second display device configured to display a second image. The imaging optical system is substantially telecentric at a real image side. The first display device is configured such that the light emitted from the first display device exhibits a substantially Lambertian light distribution. The imaging optical system and the optical member are configured such that the real image is formed between the imaging optical system and the optical member.

Abstract: A light source unit includes a display device configured to display an image, a reflective polarizing element on which light emitted from the display device is incident, a reflecting member, and a waveplate. The reflective polarizing element transmits a first polarized light and reflects a second polarized light. The reflecting member reflects, toward the reflective polarizing element, light transmitted by the reflective polarizing element. The waveplate is interposed in a portion of an optical path between the reflective polarizing element and the reflecting member. The optical path is of light emitted from the display device, transmitted by the reflective polarizing element, reflected by the reflecting member, and reflected by the reflective polarizing element. A normal of the waveplate is tilted with respect to a direction of the optical path transmitted by the waveplate partway from the reflective polarizing element toward the reflecting member.
