<P>PROBLEM TO BE SOLVED: To sufficiently illuminate an illumination cover inclined to an LED substrate. <P>SOLUTION: A side LED 60 and an angle LED 80 are mounted on the LED substrate 35. An inclined lens 36 is illuminated from an orthogonal direction based on oblique projection of illumination light on the LED substrate 35 from angle LED 80. A residual part of the lens 36 is illuminated based on irradiation of illumination light on the lens 36 from side LED 60. In such structure, side LED 60 is arranged outside the projection region E3 of angle LED 80. Since projection light from angle LED 80 is prevented from being shielded by side LED 60, the inclined lens 36 can sufficiently be illuminated in general. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
