Abstract
A vehicle headlamp is provided with a semiconductor light source and a lens. The light emission center of the semiconductor light source is arranged at a reference focal point of the lens, or in the proximity thereof. The incident surface of the lens is configured such that upper parts and the lower parts above and below the reference focal point form pairs. Light distribution patterns formed by the upper parts are shifted upwards relative to light distribution patterns formed by the lower parts. As a result, the vehicle headlamp is capable of suppressing occurrence of color bands due to lens spectral phenomena.
