Vehicle lighting assembly with stepped dimming
First Claim
1. A lighting assembly for illuminating a vehicle interior, the lighting assembly comprising:
- an elongated housing adapted to be mounted in the vehicle interior;
a plurality of electrical terminals for connection to a source of electricity;
a plurality of light emitters supported by the housing and arranged in a plurality of rows, the light emitters in each row are electrically connected between that same pair of the plurality of electrical terminals; and
a control circuit which selectively applies electricity to selected ones of the plurality of electrical terminals thereby illuminating different combinations of the plurality of rows of light emitters which results in the lighting assembly producing different light intensity levels in the vehicle interior.

Abstract
A lighting assembly for illuminating a vehicle interior has an elongated housing which supports a printed circuit board that has an electrically conductive pattern. A plurality of electrical terminals are connected to the electrically conductive pattern for coupling the lighting assembly to a source of electricity. A plurality of light emitting diodes are arranged in a plurality of rows on the printed circuit board. The light emitting diodes in each row being electrically connected in series between two of the electrical terminals. The light emitting diodes are so connected that application of electricity to selected ones of the electrical terminals causes illumination of different combinations of the rows of light emitting diodes which results in the lighting assembly producing different light intensity levels in the vehicle interior.
