<P>PROBLEM TO BE SOLVED: To provide a light source which can emit only of the light out of emission light from a light emitting diode which is emitted from an LED chip directly toward the convex lens of a molded body and is reflected by the convex lens into such a direction that an angle of divergence may become smaller and then is emitted in a regular direction. <P>SOLUTION: The light emitting diode 2 is such that the LED chip 5 is connected to a pair of leads 3 and the connecting sections are molded by the molded body 7 wherein the convex lens 8 is formed on a face facing an emission face 5a of the LED chip 5 for reflecting and emitting the emission light from the LED chip 5, in such a direction that the angle of divergence may become smaller. On the emission side of the light emitting diode 2, a condensing lens 9 is located which condenses, out of the emission light from the light emitting diode 2, only of the light which is emitted from the LED chip 5 directly toward the convex lens 8 of the molded body 7 and then is reflected by the convex lens 8 in such a direction that the angle of divergence may become smaller. A shade 10 which passes only of the light condensed at the condensing point out of the light emitted from the light emitting diode 2 and passed through the condensing lens 9 while interrupting the other light is so located as to cross the condensing point of the condensing lens 9. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
