Abstract:
1. An optical element comprising: an optical module holder; a transmitting surface section that refracts incident light emitted from a predetermined light-emitting position and transmits the light; at least one reflective surface section that reflects the incident light emitted from the light emitting position such that the light returns to a position differing and spaced apart from the light emitting position, and wherein an optical axis of the transmitting surface section and an optical axis of the reflective surface section are out of alignment in a radial direction so as to be mutually parallel; the transmitting surface section and the reflective surface section are each integrally formed with an entrance surface of a main body of the optical module holder for the light emitted from the light emitting position; said transmitting surface section is in a circular shape having a convex surface facing said light emitting position and having an optical axis aligned with a center axis of light emitted from said light emitting position; and the reflective surface section surrounds said transmitting surface section and is connected thereto.
