Abstract:
A bidirectional light sheet including at least first and second arrays of bare LED chips having 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, forming light sheets to emit light from opposite surfaces of the light sheet to create a bidirectional light sheet. The light sheet may be suspended from a ceiling to be non-parallel to the ceiling A reflector or a plurality of lenses may be included in the light sheet to emit light at any peak intensity angle to achieve a predetermined light emission pattern.
