Abstract:
A light source assembly comprising:a base member including a base portion, a plurality of first fixing portions and a plurality of second fixing portions; a plurality of light source devices fixed to said base member; and a plurality of optical elements fixed to said base member and each including a side surface and a surface through which a light beam issuing from a particular one of said plurality of light source devices is transmitted; said plurality of first fixing portions being substantially equal in number to said plurality of light source devices, said plurality of light source devices each being fixed to a particular one of said plurality of first fixing portions such that a light beam issuing from the light source device is propagated in a preselected direction; said plurality of second fixing portions being substantially equal in number to said plurality of optical elements and located downstream of said plurality of first fixing portions in a direction of propagation of light beams issuing from said plurality of light source devices; said plurality of second fixing portions each including a support surface substantially identical in configuration with said side surface of an associated one of said plurality of optical elements, said support surface being substantially parallel to a direction of pitch of said light beams said direction of pitch being a direction perpendicular to the direction of propagation of the light beams through said plurality of optical elements, whereby a gap between said support surface of each of said plurality of second fixing portions and an associated one of said plurality of optical elements is substantially uniform to allow adhesive filling said gap to be uniformly cured.
