US Patent 8207549 - LED package with CNT electrodes

LED packaging includes metal electrodes which reduce the light emission efficiency. This patent from Foxconn teaches instead using carbon nanotube material to overcome this problem. Claim 1 reads:

1. A light emitting diode package, comprising:

a housing; and

a light emitting unit received in the housing, the light emitting unit comprising:

a first carbon nanotube layer;

at least two spaced light emitting chips formed on the first carbon nanotube layer; and

a second carbon nanotube layer covering the at least two spaced light emitting chips;

wherein the light emitting unit further comprises a light reflective layer formed on an outer surface of the first carbon nanotube layer.
