US Patent 8207549 - LED package with CNT electrodes

http://www.freepatentsonline.com/8207549.html

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.
