Abstract: In an exemplary configuration, a lens array and a light module using the same include a first lens surface 11 and a second lens surface 12 formed into surface shapes such that by expanding the luminous flux diameter of light as the light travels from the first lens surface 11 toward the second lens surface 12, a light spot on the second lens surface 12 is larger in diameter than a light spot on the first lens surface 11, whereby the effects on optical performance by foreign objects and scratches on the lens surface can be mitigated, the criteria for the outward appearance of the lens surface can therefore be mitigated and the yield rate improved, and costs can be reduced.

Abstract: This light receptacle comprises: first optical surfaces on which light beams emitted from light emitting elements are respectively caused to be incident; second optical surfaces which emit the light beams incident on first optical surfaces respectively toward the end faces of light transmission bodies; a third optical surface which reflects the light beams incident on the first optical surfaces toward the second optical surfaces; and recesses which are formed in the surface on which second optical surfaces are arranged. The distance between the centers of two adjacent first optical surfaces before mold release and the distance between the centers of two adjacent second optical surfaces before mold release during injection molding are shorter than the distance between the optical axes of light beams emitted from two adjacent light emitting elements that are arranged so as to face each other.
