<P>PROBLEM TO BE SOLVED: To radiate light from LEDs in a long linear line, while improving utilization efficiency of light flux. <P>SOLUTION: The lamp fitting 1 includes LEDs 2, a light guide 3 arranged in front of the LEDs 2, and reflecting faces 41 arranged at either side of the light guide 3 in a Y direction. The light guide 3 includes a first incident face 311 opposed to each LED 2, and a second incident face 312 erected toward an LED 2 side from a peripheral edge of the first incident face 311. A part of ultraviolet rays incident from the second incident face 312 is made emitted to either side in a Y direction, and the rest of the ultraviolet rays is made irradiated toward front while it is branched to either side in an X direction to be irradiated on two first irradiated regions R1 separated in the X direction. The reflecting face 41 reflects forward the ultraviolet rays emitted to either side in the Y direction from the light guide 3 to be irradiated on a second irradiated region R2 that is a region between the two first irradiated regions R1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
