Abstract
Abstract A circuit for internal illumination of motor vehicles having a controller, coupled to the internal illumination, that automatically turns the internal illumination on and off as a function of operating state parameters of the motor vehicle according to a predetermined switching program. The controller is a deliberately operable electrical controller. The circuit also includes a control device, coupled to and controlled by the controller, that switches the switching program off and the internal illumination permanently on in response to being controlled by the controller.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
106 words
Circuit for internal illumination of motor vehicles comprising: a controller, coupled to the internal illumination, that automatically turns the internal illumination on and off as a function of operating state parameters of the motor vehicle according to a predetermined switching program, wherein the controller is a deliberately operable electrical controller; a control device having a switching command input, coupled to and receiving switching commands from the controller, said control device further having an output for providing illuminating current to the internal illumination, wherein said control device switches the switching program off and the internal illumination permanently on in response to a switching command from the controller.
Claim 2
Dependent Claim
106 words
Circuit for internal illumination of motor vehicles comprising: a controller, coupled to the internal illumination, that automatically turns the internal illumination on and off as a function of operating state parameters of the motor vehicle according to a predetermined switching program, wherein the controller is a deliberately operable electrical controller; a control device having a switching command input, coupled to and receiving switching commands from the controller, said control device further having an output for providing illuminating current to the internal illumination, wherein said control device switches the switching program off and the internal illumination permanently on in response to a switching command from the controller.
Claim 3
Dependent Claim
14 words
Circuit according to claim 1, wherein an on-time of the internal illumination is limited.
Claim 4
Dependent Claim
18 words
Circuit according to claim 2, wherein the internal illumination is switched off when a locking command is received.
Claim 5
Dependent Claim
33 words
Circuit according to claim 3, wherein the control device includes means for switching off the internal illumination when a switching state is present which is representative of turning off of the motor vehicle.
Claim 6
Dependent Claim
