Patent ID: 8277074

Claim:
An apparatus comprising: a planar organic light emitting diode material having a length of least 5 cm and a width dimension being equal to or less than the length dimension, said organic light emitting diode material configured to have a low profile of less than 10 mm in thickness; a battery connected to the organic light emitting diode material for providing a voltage source of about 10 volts or less, said battery having a length and width dimension equal to or less than the organic light emitting diode material, a switch electrically connected between the battery and the organic light emitting diode material, the switch operable between an on and off position; a substrate to which said light emitting diode material, said battery and said switch are fixed; said substrate, said light emitting diode material, said switch and battery having a combined thickness of about 10 mm or less; and a mechanism for removably securing said substrate with the organic light emitting diode material thereon to a surface in an area to be subjected to light, wherein the battery is independently removable from the apparatus for at least one of replacement and recharging.
