Abstract
Abstract An electric light, especially for illuminating the interior of a motor vehicle. The light includes a sensor that is at least electrically connected with the light and that, without a switch, senses the opening of at least one door that leads to the interior of the vehicle. After the opening of the door has been detected, a signal is delivered to a switching mechanism that turns on the electric light for a predetermined and possibly selectable period of time.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
103 words
An electric light switching arrangement for illuminating an interior of a motor vehicle, comprising: a sensor that is electrically connected to said light, with said sensor sensing an opening of at least one door of said vehicle that leads to said interior thereof and subsequently delivering a signal to a switching mechanism that then turns said light on for a predetermined period of time; and a transmitter disposed in said interior of said vehicle for generating an alternating field, wherein said sensor is responsive to a change of said alternating field resulting from said opening of at least one door of said vehicle.
Claim 2
Dependent Claim
103 words
An electric light switching arrangement for illuminating an interior of a motor vehicle, comprising: a sensor that is electrically connected to said light, with said sensor sensing an opening of at least one door of said vehicle that leads to said interior thereof and subsequently delivering a signal to a switching mechanism that then turns said light on for a predetermined period of time; and a transmitter disposed in said interior of said vehicle for generating an alternating field, wherein said sensor is responsive to a change of said alternating field resulting from said opening of at least one door of said vehicle.
Claim 3
Dependent Claim
41 words
An electric light switching arrangement according to claim 1, which includes at least one electrical current pulse relay, a retention time of which can be set in conformity with a desired period of time for said light to be turned on.
