<P>PROBLEM TO BE SOLVED: To realize an illuminating device which can be configured to be compact, designed/manufactured easily and which does not produce illumination shadow in an illumination part. <P>SOLUTION: An illuminating device comprises: a light source 1 in which plural LEDs are arrayed in one direction; a light guide body 3; and a mirror part material 5 which reflects light emitted from an emission end face of the light guide body to a linear part to be illuminated. The light guide body 3 is arranged so that its emission end face 3B is on a side opposite to the mirror part material 5 through a normal line surface FA orthogonal to the part to be illuminated including a longitudinal direction of the linear part LA to be illuminated. A magnitude relation of inclination angles θa, θb of inclined planes SA and SB of a light distribution control area 3C formed on a surface with respect to an external normal line is θa<θb, and the light guided by the light guide body 3 to emit on a part to be illuminated from the light distribution control area 3C is formed to be emitted to a part to be illuminated from the opposite side of the normal line surface FA from the light reflected by the mirror part material 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
