<P>PROBLEM TO BE SOLVED: To provide a LED light-emitting device moving a focusing position of a lens face. <P>SOLUTION: A plurality of stepped pins 13A, 13B are provided on a lens body 11. These stepped pins 13A, 13B have at least one step each, and at least one pair of stepped pins whose shape of step and dimension are same are arranged at the positions facing each other with lens surface 12 sandwiched. At least two kinds of pins have different numbers of steps. A plurality of holes 2A, 2B engaging with stepped pins 13A, 13B of the lens body 11, are provided on a substrate 1. Stepped pins 13A, 13B of the lens body 11 engages with holes 2A, 2B having diameters corresponding to predetermined diameters of stepped pins to determine a focusing position of lens face. Holes engaged with stepped pins are changed by rotating the lens body, thereby the focusing position of lens face moves. <P>COPYRIGHT: (C)2009,JPO&INPIT |
