Abstract
A high and low beam integrated vehicle lamp lighting device, a vehicle lamp, and a vehicle. The lighting device comprises a first light source, a first light-condensing element, a second light source, a second light-condensing element, a light distribution element, and a lens; the first light-condensing element is arranged to be capable of condensing light emitted by the corresponding first light source and making the light projected through the lens by means of the light distribution element to form a low beam shape, and the second light-condensing element is arranged to be capable of condensing light emitted by the corresponding second light source and making the light projected through the lens by means of the light distribution element to form a high beam shape, wherein the light exit direction of at least one of the first light-condensing element and the second light-condensing element intersects with a light shape projection direction.
