<P>PROBLEM TO BE SOLVED: To effectively utilize reflected light even when a twice reflection type optical system is used. <P>SOLUTION: This vehicular marker lamp is provided with: LEDs 20 each arranged with an optical axis L directed toward the front side of the lamp; a lens 12 disposed in front of the LEDs 20; and reflectors 26 disposed around the LEDs 20. On the lens 12, curved reflecting surfaces 42 each used for reflecting light from the LED 20 toward the reflector 26 to form a virtual light source image 44 of reflected light thereof at a position separated from the optical axis L, and transmission parts 34 for transmitting, to the front side of the lamp, re-reflected light in reflecting again, on reflecting surfaces 30 of the reflectors 26, the reflected light reflected on the curved reflecting surface 42 are formed; and each reflecting surface 30 is formed into a curved surface shape having a focal point at the position of the virtual light source image 44. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
