Abstract

[Problem] It is important to suppress the occurrence of color bands due to lens spectral phenomena. [Solution] This invention is provided with a semiconductor light source (2) and a lens (3). The light emission center (O) of the semiconductor light source (2) is arranged at a reference focal point (F) of the lens (3), or in the proximity thereof. The incident surface (30) of the lens (3) is configured such that upper parts (3A, 3C, 3E) and the lower parts (3B, 3D, 3F) above and below the reference focal point (F) form pairs. Light distribution patterns (SPA, WPC, WPE) formed by the upper parts (3A, 3C, 3E) are shifted upwards relative to light distribution patterns (SPB, WPD, WPF) formed by the lower parts (3B, 3D, 3F). As a result, the present invention is capable of suppressing occurrence of color bands due to lens spectral phenomena.
