Abstract: A light source device includes: a plurality of first semiconductor light sources; a condenser lens; and a light guide having a prismatic shape in which an incident surface is on a first side of a central axis direction of the prismatic shape and an emission surface is on a second side of the central axis direction of the prismatic shape, a positional relationship between the plurality of first semiconductor light sources, the condenser lens, and the light guide is set such that a traveling direction of the light incident on the incident surface from the first semiconductor light sources via the condenser lens is perpendicular to a reflecting surface of the light guide in a plan view as viewed in the central axis direction of the prismatic shape, the incident light being reflected on the reflecting surface in the light guide.

Abstract: An optical component includes: a lens that includes a lens surface and a tapered side surface, the tapered side surface extending from an outer circumference of the lens surface in an axial direction that intersects the lens surface and having an outer diameter progressively larger away from the lens surface. A center of the outer circumference of the lens surface is displaced, in a direction intersecting the axial direction, from a center of an outer circumference of the side surface at a position distanced from the lens surface in the axial direction. The optical component may further include a frame body in which the lens is fitted. The frame body may include a tapered engaging surface corresponding to the side surface of the lens. The lens may be fitted in the frame body and is positioned in a circumferential direction about the axial direction.

Abstract: An illuminating device includes: a light source; a light guide element; and a deflecting element that has a deflecting surface for deflecting illumination light coming from the light source towards a light-incident end of the light guide element and that makes the illumination light incident on the light-incident end at incident angles according to deflection angles. The deflecting element is configured to change, between a first deflection angle and a second deflection angle, the deflection angle of the illumination light at each position on the deflecting surface and deflects the illumination light simultaneously at the first deflection angle and at the second deflection angle. A first portion deflected at the first deflection angle and a second portion deflected at the second deflection angle are both incident on the light-incident end.
