Abstract
A bidirectional light sheet including at least a first and second array of bare LED chips with top and bottom electrodes, where the arrays of LEDs are sandwiched between at least two transparent substrates having conductors bonded to the electrodes without wires to form the light sheet. The LEDs of the array are arranged within the light sheets to emit light from opposite surfaces of the light sheet to create a bidirectional light sheet. The bidirectional light sheet is suspended from a ceiling to be non-parallel to the ceiling.
