Abstract: A light source module includes a light source and a first optical element. The light source is configured to emit first and second light beams. The first optical element has a first surface on which the first second light beam are to be incident. The first light beam and the second light beam are incident on the first surface along a first direction such that the first light beam is incident at a first position on the first surface and the second light beam is incident at a second position on the first surface. The first light beam has a first width in a second direction intersecting the first direction on the first surface, and a second width in a third direction intersecting a plane including the first direction and the second direction on the first surface. The first width is greater than the second width. The second light beam has a third width in the second direction on the first surface, and a fourth width in the third direction on the first surface. The third width is greater than the fourth width. A direction from the second position to the first position intersects the third direction. The first light beam has a first peak wavelength, and the second light beam has a second peak wavelength different from the first peak wavelength of the first light beam. The first optical element has an optical power in the second direction greater than an optical power of the first optical element in the third direction.

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: A light source module includes a light source configured to emit a first light beam, a first optical element having a first surface on which the first light beam is incident along a first direction, the first surface including a first region on which at least a portion of the first light beam is incident, and a second surface from which the first light beam is emitted, and a second optical element on which the first light beam having emitted from the first optical element is incident. The first light beam has a first width along a second direction and a second width along a third direction. The first width is greater than the second width. The first region has a protruding shape in a first cutting plane including the first and second directions, and has a recessed shape in a second cutting plane including the first and third directions. The second surface has a protruding shape in the first and second cutting planes.
