<P>PROBLEM TO BE SOLVED: To provide a vehicle lighting device capable of clearly illuminating an illumination pattern of a desired light distribution. <P>SOLUTION: An optical axis O' of a lens part 21 of an optical member 20 is inclined more downward than a horizontal direction (an optical axis O of each of LEDs 12) with a light emitting portion 12a of each of the LEDs 12 as a reference. With this, a region below the horizontal position of the lighting device 1 is illuminated by the lens part 21, while each of the LEDs 12 is arranged at an optically ideal position with respect to the lens portion 21. Further, each of reflection faces 22c, 23c of an upper-side reflector portion 22 and a lower-side reflector portion 23 of the optical member 20 is set up based on each of different parabolas P1, P2 with each of the LEDs 12 as each of focuses F1, F2. With this, the region horizontal or lower in relation to the lighting device 1 is illuminated by each of the reflector portions 22, 23, while each of the LEDs 12 is arranged at an optically ideal position with respect to each of the reflector portions 22, 23 also. <P>COPYRIGHT: (C)2010,JPO&INPIT |
