Abstract: This invention relates to illumination systems, namely, to automotive headlamps and can be used as the principal head lighting of light and cargo vehicles. The automotive headlamp includes at least one LED and a system of lenses. The system of lenses includes both composite diverging and regulating lenses. The composite diverging lens is made up of two plano-concave lenses. The composite regulating lens is made up of the converging plano-convex lens and the refracting right-angled wedge placed in a series through the luminous flux. The composite regulating lens is placed between the LED and the composite diverging lens, which is suitable for controllable obscuration of the light flux. The invention enhances the reliability of the high/low-beam switch system.

Abstract: A light source contains at least one light-emitting diode installed in the casing or on the base, and a lens system located along the light flux. The lens system comprises a plane-convex lens, a first plane-concave lens, and a composite lens 4 that are located along the light flux. The composite lens 4 is made up of a second and third plane-concave lenses. Flat surfaces of all of the lenses 4 are outflow faces for the light flux. Axes of symmetry of the second and third plane-concave lenses are normal to each other, whereas axes of symmetry of the first and second plane-concave lenses are parallel to each other. The first plane-concave lens is made movable along the light flux, and has a relocation drive therefor. A solenoid or an electric motor with a gear can be used as the drive. The technical result of the invention is believed to be the improvement of performance indicators, and the structure simplification.
