<P>PROBLEM TO BE SOLVED: To provide a linear lighting device that easily forms linear illuminating light with uniform illuminance by an inexpensive configuration. <P>SOLUTION: A plurality of light-source parts 5 are linearly arrayed according to a required length of a light source so as to configure a light source 2, thereby inexpensively and easily configuring the light source 2. A light-guide part 20 is configured such that its light-incident face 21 faces such a light source 2 astride a plurality of light-emitting face parts 11. The light-guide part is arranged with respect to the light source. Each recessed part 23 corresponding to each gap between light-emitting face parts 11 is recessed in the light-incident face 21 of the light-guide part 20. By this, each half-mirror part 23a is protrudingly formed inside the light-guide part 20. Further, each diffuse-reflection member facing each recessed part 23 in the gap between the respective light-emitting face parts 11 is arranged on the light source 2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
