Abstract (en)
[origin: CN109578929A] The invention relates to a lighting device (1) for a motor vehicle headlight comprising a reflector (2) with a total reflection surface (2a) for reflecting light at least partially in the direction ofan optical axis (x) of the reflector, a first and a second light source (3', 3'') for irradiating light onto the reflector (2), wherein the first and the second light source (3', 3'') are at least ina direction normal to the optical axis (x) of the reflector (2) spaced from each other, the total reflection surface (2a) of the reflector (2) has a number of first reflection sub-areas (2a ') facingthe first light source (3'), which image the light irradiated by the first light source (3') in the form of at least one first light distribution the first light function are set up, wherein the total reflection surface (2a) of the reflector (2) comprises a number of second reflection sub-areas (2a') facing the second light source (3'') is, which are configured to image the incident light from the second light source (3 '') in the form of a second light distribution of a second light function, wherein the first light distribution is different from the second light distribution.
