Abstract: The invention relates to a circuit arrangement (1) for a vehicle lamp, comprising a number of N light units, a first electronic switch (5), a second electronic switch (6), a logic circuit (7) and a driver unit (8) that comprises N+1 current regulators, N+1 data registers and a communication interface (17), wherein each light unit (2, 3, 4) comprises a first LED type (21) in a first LED path (23) and a second LED type (22) in a second LED path (24), wherein each light unit (2, 3, 4) is connected to one current regulator (9, 10, 11) providing an individual current (I1, I2, I3) to each light unit (2, 3, 4), wherein a non-conducting conduction state of the first electronic switch (5) interrupts the first LED path (23) and wherein a non-conducting conduction state of the second electronic switch (6) interrupts the second LED path (24), wherein the logic circuit (7) is configured to alternately change on the basis of a control current (Ic) the conduction state of the electronic switches (5, 6), wherein each data re

Abstract: Illumination device for a motor vehicle headlight. The device has a light source, a light-permeable body (LPB), a light injection element for injecting light from the light source into the LPB, and a projection device. Light from the light source forms a light distribution with a cut-off line formed by a screen edge of a screen device, which is formed by a boundary surface of the LPB. A sign light light source (SLLS) and a further sign light light injection element (SLLIE) associated with the SLLS are provided. The SLLIE forms the light emitted by the SLLS into a third light beam and directs the third light beam onto the boundary surface, which re-enter the LPB and are projected by the projection optics device as a sign light light beam into a region of the light distribution lying above the cut-off line and are displayed as sign light light distribution.
