Abstract
Abstract An elongated cornice lighting fixture in a public transit vehicle coupled with an advertising display panel is mounted above the windows on each side of the vehicle. Light from incandescent bulbs in each fixture is controlled by sheets of reflective optical film to direct the light to the seating area below each fixture and to the display panel associated with the opposite fixture with only minimal illumination of the vehicle floor and windows.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
In a public transit vehicle having side windows, an aisle extending along the longitudinal axis of the vehicle and a passenger seating area on either side of the aisle, a lighting fixture arrangement for preferentially illuminating the seating area and minimizing the illumination of the aisle and side windows, comprising: a lighting fixture above each passenger seating area, each fixture having an elongated light housing extending generally parallel to the aisle, the housing comprising an upper surface, an adjacent side surface, and a translucent cover having a side wall spaced from the said side surface and a bottom wall spaced from the upper surface to define a cavity, a plurality of spaced incandescent lamps within the housing, and optical means positioned in the housing adjacent each lamp to receive light from the adjacent lamp for preferentially directing light from the lamps through the bottom wall of the translucent cover to the seating area, whereby the seating area is illuminated at a higher level than the aisle and the side windows.
Claim 2
Dependent Claim
170 words
In a public transit vehicle having side windows, an aisle extending along the longitudinal axis of the vehicle and a passenger seating area on either side of the aisle, a lighting fixture arrangement for preferentially illuminating the seating area and minimizing the illumination of the aisle and side windows, comprising: a lighting fixture above each passenger seating area, each fixture having an elongated light housing extending generally parallel to the aisle, the housing comprising an upper surface, an adjacent side surface, and a translucent cover having a side wall spaced from the said side surface and a bottom wall spaced from the upper surface to define a cavity, a plurality of spaced incandescent lamps within the housing, and optical means positioned in the housing adjacent each lamp to receive light from the adjacent lamp for preferentially directing light from the lamps through the bottom wall of the translucent cover to the seating area, whereby the seating area is illuminated at a higher level than the aisle and the side windows.
Claim 3
Dependent Claim
47 words
The invention as defined in claim 1 wherein the optical means adjacent each lamp comprises a reflective panel of transparent material having grooves on the side opposite the incident light from the lamp for reflecting the light in a controlled pattern to selectively illuminate the seating area.
Claim 4
Dependent Claim
80 words
The invention as defined in claim 1 wherein an elongated display area is disposed above the windows adjacent each fixture and wherein, each fixture has within its housing second optical means adjacent each lamp to receive light from the adjacent lamp for preferentially directing light from the lamps through the side wall of the translucent cover to the display area on the other side of the aisle, whereby the display area is illuminated at a higher level than the windows.
Claim 5
Dependent Claim
48 words
The invention as defined in claim 3 wherein the second optical means adjacent each lamp comprises a reflective panel of transparent material having grooves on the side opposite the incident light from the lamp for reflecting the light in a controlled pattern to selectively illuminate the display area.
Claim 6
Dependent Claim
30 words
The invention as defined in claim 3 wherein the optical means and the second optical means are respectively mounted on the upper surface and the side surface of the housing.
