Abstract

A fluorescent lighting fixture provides shadowless linear lighting. A support member is provided for supporting a plurality of lamp supports. The lamp supports support the fluorescent lamps on an angle, so that the non-socket end of the fluorescent lamp overlaps the socket of an adjacent lamp so as to provide shadowless linear lighting.

Claims

1. A lighting fixture for fluorescent lighting, comprising:

a) a support member having an upper surface;

b) a plurality of ramps mounted on the upper surface of said support member;

c) each of said plurality of ramps having a lower end and a higher end, with the lower end of one ramp being adjacent to the higher end of an adjacent ramp; and

d) a socket for receiving a fluorescent lamp mounted adjacent to the lower end of each ramp, with the length of each ramp being less than the length of the fluorescent lamp and socket, so that the non-socket end of one fluorescent lamp mounted on the higher end of one ramp overlaps the socket end of an adjacent fluorescent lamp mounted on the lower end of an adjacent ramp so as to provide shadowless and continuous linear lighting.

2. A lighting fixture in accordance with claim 1, wherein said plurality of ramps are mounted in a straight line and one of said sockets are mounted on the lower end of each of said plurality of ramps.

3. A lighting fixture for mounting fluorescent lamps, comprising:

a) a support member having an upper surface;

b) a plurality of lamp supports mounted on the upper surface of said support member for engaging and supporting said fluorescent lamps adjacent their non-socket ends;

c) said plurality of lamp supports being equally spaced apart in a straight line;

d) a plurality of sockets corresponding to said plurality of lamp supports for receiving said fluorescent lamps mounted on the upper surface of said support member and being equally spaced apart in a straight line each of said plurality of sockets being adjacent the socket end of one of said fluorescent lamps; and

e) the spacing between each of said plurality of sockets and each of said corresponding lamp supports being less than the length of one of said fluorescent lamps, so that the non-socket end of one fluorescent plurality of lamps mounted on one of said lamp supports overlaps the socket end of an adjacent fluorescent lamp so as to provide shadowless and continuous linear lighting.

4. A lighting fixture in accordance with claim 3, wherein said plurality lamp supports are posts mounted on the upper surface of said support member.
