Abstract (en)
[origin: US4859043A] A motor vehicle signal lamp of the type comprising a light source (12) and deflector means for causing the rays emitted by the source to propagate in a direction which is essentially parallel to a given general emission direction (x-x), wherein the deflector means comprise a first lens (20) which is generally balloon-shaped and disposed around the source and in proximity thereto, and a second lens (30) which is generally in the form of a plate disposed in front of the source (12) and of the first lens (20) and which extends transversely to the general emission direction, wherein the first lens comprises deflector elements (22; 23) for causing the light rays it receives from the source to be deflected at least vertically towards said second lens, and wherein the second lens (20) includes deflector elements (32, 34) for deflecting the light rays it receives from the first lens at least horizontally to a direction which is substantially parallel to said general emission direction (x-x). The invention also provides means on the first lens for distributing light flux so as to cause the distribution of light on the illuminated area to be highly uniform in the direction of its width.
