Abstract:
There are instances of vehicular lighting in prior art where a significant amount of effectively distributed light radiating from a projection lens is lost. The invention is provided with a semiconductor-type light source (2) and a projection lens (3). The projection lens (3) has an optically active portion (32) transmitting light from the semiconductor-type light source (2), and an optically inactive portion (33). The optically inactive portion (33) of the projection lens (3) is provided with a trimmed portion (33U, 33D) resulting from cutting away a portion of a base shape. As a result, the invention allows the amount of loss in the effectively distributed light radiating from the projection lens (3) to be as small as possible.
