Abstract

A task light for use in modular office furniture includes a housing having a peripheral frame defining a display area. The frame has a hollow chase. A plurality of circuit boards are mounted to the housing within the display area. Each circuit board has a plurality of light emitting diodes arranged to emit light from the display area. A plurality of electrical conductors are routed within the frame through the hollow chase. Each electrical conductor is connected with a corresponding circuit board.

Claims

1. A task light for use in modular office furniture, comprising:

a housing having a peripheral frame defining a display area, said frame having a hollow chase, said housing including a back plate, said frame having a generally U-shaped cross section with an open end, said open end being positioned against said back plate;

a plurality of circuit boards, mounted to said housing within said display area, each said circuit board having a plurality of light emitting diodes arranged to emit light from said display area, said plurality of circuit boards arranged in plurality of rows, each said row including a plurality of said circuit boards; and

a plurality of electrical conductors routed within said frame through said hollow chase, each said electrical conductor connected with a corresponding said circuit board.

2. The task light of claim 1, said frame having a generally rectangular shape and lying about a periphery of said back plate.

3. The task light of claim 2, including a power cable connected with said frame, said plurality of electrical conductors being electrically connected with said power cable.

4. A modular office furniture assembly, comprising:
