Abstract

DC60 (22/06/54) Although the structure of base 101 in the comparative example shown in Figure 7(b) is simple, the upper part of the lens becomes darker because the LEDs 102, 103 are farther from lens 107, while the lower part of the lens becomes brighter because the LEDs 105, 106 are closer to lens 107. The brightness above the surface of lens 107 should not be uniform. Figure 7(a) shows this fabrication, which was adjusted to provide uniform brightness above lens 51 by arranging LEDs 54-58 in a manner significantly parallel to the tilted lens 51. In order to do so, a base for supporting LEDs 54-58 was formed. A stepped base 52 is formed, and a reflective surface is provided on the back surface of the stepped base 52. Although the structure of base 101 in the comparative example shown in Figure 7(b) is simplified, the top of the lens becomes the darker area because the illuminating diodes 102, 103 are farther from lens 107, while the bottom of the lens becomes the brighter area because the illuminating diodes 105, 106 are closer to lens 107. The brightness above the surface of lens 107 should be uneven. Figure 7(a) shows this invention, which is adjusted to provide uniform brightness above lens 51 by placing the illuminating diodes 54-58 in approximately parallel fashion to the tilted lens 51. To do so, the base supporting the illuminating diodes 54-58 is formed into a stepped base 52, and a reflective surface is provided on the back surface of the stepped base 52.

Claims (2)

1. A vehicle with a taillight consisting of a slanted lens (51) with a predetermined cross-sectional area (72L,72R) of which a stepped base (52) is formed in a stepped pattern to ensure approximate spacing to the lens (51), and a number of light-emitting diodes (54-58) mounted on the stepped base to ensure approximate spacing to the lens (51), which is characteristic of motorcycles in that the taillight is mounted on motorcycles in such a way that the lens (51) is generally slanted longitudinally along the motorcycle in such a way that the upper part of the lens (51) is positioned toward the rear and the lower part of the lens (51) is positioned toward the front, where, within the outer contour of the lens (51), the cross-sectional area of the lens (72L,72R) is bounded to form an approximate circle in the rear view, while the stepped base (52) has an outer diameter or contour almost equal to the cross-sectional area of the lens (72L,72R) in the rear view; And where the reflective surfaces (53,53R,53L) are formed on the back surface of the stepped base (52). 2. The vehicle under claim 1 in which an angular projection (62) provided from the upper surface (61) of the lens (51) of the taillight is inserted into a cavity (63) formed within the rear fairing (47) of the motorcycle.
