ABSTRACT:
A vehicle lamp including a projector headlight using an LED light source for a low beam can include a shade, an LED light source, an ellipsoidal reflector and a projector lens. Both a focus of the projector lens and a top edge of the shade can be located near a second focus of the reflector. The LED light source can be located near a first focus located below the second focus of the reflector. Therefore, light emitted from the LED light source can be effectively gathered near the focus of the projector lens via the reflector and can be projected via the projector lens with high light use-efficiency. The projector lens can include light dispersing portions or structures on an upside and downside thereof for reducing chromatic aberration. Thus, the lamp can project a favorable light distribution that can conform to light distribution standards for vehicle headlights and the like.
