A motor vehicle headlamp having a first reflection module, including a first reflector, a first group of LED chips and a second group of LED chips, having a second reflection module, which comprises a second reflector, a third group of LED chips and a fourth group of LED chips, and having a control circuit, which is configured to control the current flow through the light emitting diodes, and which is configured to activate the LED chips of the first group together with the LED chips of the fourth group, wherein the LED chips of the second group and the LED chips of the third group are deactivated. The control circuit activates the LED chips of the second group together with the LED chips of the third group, wherein the LED chips of the first group and the LED chips of the fourth group are deactivated.
A motor vehicle headlamp having a first reflection module, which comprises a first reflector, a first group of LED chips and a second group of LED chips, wherein the LED chips of the second group are disposed offset to the LED chips of the first group in a main beam direction (z) of the first reflector, a second reflection module, which comprises a second reflector, a third group of LED chips, and a fourth group of LED chips, wherein the LED chips of the fourth group are disposed offset to the LED chips of the third group in a main beam direction of the second reflector, and a control circuit, which acts to control the current flow through the LED chips, and which activates the LED chips of the first group together with the LED chips of the fourth group in a first switching state, said control circuit activates the LED chips of the second group together with the LED chips of the third group when in a second switching state, wherein the LED chips of the first group and the LED chips of the fourth group are deactivated in the second switching state and wherein the LED chips of the second group are disposed at a greater spacing to a light exit surface of the first reflector than the LED chips of the first group.
