<P>PROBLEM TO BE SOLVED: To provide a linear LED lighting device to be a substitute of a cold-cathode tube, by fully diffusing emission of LEDs as point light sources. <P>SOLUTION: The device is provided with a triangle-pole shape light transmission diffusion part 1a having an emission face 1e, a first reflecting face 1f, and a second reflecting face 1g formed with light-scattering particles uniformly dispersed in three dimensions in transparent resin, and a first reflecting part 1i as well as a second reflecting part 1j pasted on the first reflecting face 1f as well as the second reflecting face 1g, respectively. A plurality of communicating windows 1c communicating with the second reflecting face 1g are formed at the second reflecting part 1j along a length direction of the light transmission diffusion part 1a, and ruggedness treatment parts 1d are formed at the second reflecting face 1g at a position where the communicating windows 1c are formed, each communicating window 1c having an LED 3 insertion-fitted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
