    • PROBLEM TO BE SOLVED: To eliminate the generation of light irradiated beyond the range of control and light stagnation caused by a stepped part formed between adjacent segments, and to expand the range of light diffusion in left and right direction.
      SOLUTION: Reflection surfaces 2, divided into a plurality of segments A1-A4 of which, emission angle, emitting the light from a light source bulb 4 mounted to a bulb insertion hole 3, are different from each other, are formed into a freely curved surface having a bulb insertion hole 3 at the central part. Out of those plurality of segments, the segments adjacent to each other in left to right direction, for example, the segment A1 and A2, are formed so that the nearer the segment locates to the bulb insertion hole 3, the more backward the position of the reflection surface of the segment is shifted, and a slanted surfaces, passing through the middle part T1 of the width T of the position shift at the part corresponding to the boundary M of the segment A1 and A2, are jointed by a loose jointing reflection surface 6 formed so as to extend toward left and right side.

    • PROBLEM TO BE SOLVED: To provide a passing light distribution pattern capable of securing moderate illumination before a road surface without deteriorating the distant visibility. SOLUTION: Boundary portions S1 and S2 between middle diffusion control bases B, C and a large diffusion control face A except a traveling beam control face F in a reflection face 2, and a horizontal cut control face E and a 15 deg. cut control face D, are formed such that the upper control face A (B, C) is positionally shifted in front of the lower control face D (E), and both control faces A (B, C) and D (E) are continued in a connection reflection face 6 formed of a gentle slope passing through a nearly middle part b of a positional shift width h in a boundary center portion (a) of both control faces A (B, C) and D (E), extended forward and downward. Because the connection reflection face 6 is formed more downward than the upper control faces A, B, C or the lower control faces D, E emission light from the connection reflection face 6 is emitted at more downward emission angles than the upper control faces A, B, C and the lower control faces D, E.

    • PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture of which the region of emission can be broadened, and the decline of appearance can be prevented even when a light diffusion prism element is installed at one part of a transparent outer-lens.
      SOLUTION: Light L3 guided with a light-guide body 16 by an emission part 17 can be diffused and emitted outside by guiding the light from a light source 10 of a front turn signal lamp 3 to a prescribed position by the light guide body 16. As a result of this, light emitting ranges A3I, A3O can be broadened. Furthermore, because the light emitting ranges A3I, A3O are broadened by the light guide body 16 and the emission part 17, it is not necessary to install the light diffusion prism element. As a result of this, even if the outer-lens 5 is transparent, the decline of the appearance is prevented by installing the light diffusion prism element at the outer-lens 5.

    • 要解决的问题:为了提供可以扩大发射区域的车辆照明器具,并且即使当光扩散棱镜元件安装在透明外透镜的一部分时也可以防止外观的下降 。 解决方案:通过发射部分17由导光体16引导的光L3可以通过将来自前转向信号灯3的光源10的光引导到光导体的规定位置而被散射并发射到外部 作为其结果,可以扩大发光范围A3I,A3O。 此外,由于通过导光体16和发射部17使发光范围A3I,A3O变宽,所以不需要安装光扩散棱镜元件。 结果,即使外透镜5是透明的,通过将光漫射棱镜元件安装在外透镜5来防止外观的下降。(C)2005,JPO和NCIPI

    • PROBLEM TO BE SOLVED: To improve side visibility by enlarging a horizontal width of a light distribution pattern without generating a light pool and emission light outside the control range.
      SOLUTION: A reflection face 2 is formed in a free curve face with a bulb installation hole 3 in a center portion, while the reflection face 2 divided into a plurality of segments different in an emission angle of light of a light source bulb 4 installed in the bulb installation hole 3. The plurality of segments comprises a plurality of convex reflection faces A, B, etc., and concave reflection faces (a), b, etc., which horizontally alternately continue. A boundary portion between both reflection face A (B, etc.), (a) (b, etc.), is a connection refection face 7 passing through a nearly middle point of an offset width h, formed by extending a gentle slope intersecting a standard paraboloid S at a larger intersection angle than an intersection angle between the standard paraboloid S, and the convex reflection face A (B, etc.), and the concave reflection face (a) (b, etc.), in the right and left direction. In the boundary portion, the convex reflection face A (B, etc.), and the concave reflection face (a) (b, etc.), between a connection width H are continued.
