Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To provide an illuminating device having a front end surface of a light guide body as an illuminating region capable of preventing degradation of quality and unevenness of illumination in viewing from a slant front side and suppressing an increase in cost. SOLUTION: This illuminating device comprises a light guide body 3 having a serration 5a on a back end surface 5 with a front end surface 4 seen with eyes, and an LED 7 arranged opposite the back end surface 5 of the light guide body 3. A plurality of recessed parts 6a are provided on a side surface 6 of the light guide body 3 by spacing a predetermined interval P2 wider than a pitch P1 of the serration 5a. With this structure, when light is emitted from the LED 7, passes through the serration 5a, and travels toward the side surface 6 of the light guide body 3, directions of reflected light of light traveling to the recessed parts 6a and light traveling to the flat parts 6b not having the recessed parts 6a are different.  Thus approximately equal illumination states can be made in a region in the front end surface 4 illuminated by the light reflected on the side surface 6 and in other region of the front end surface 4 less affected by the light reflected on the side surface 6.
