Patent ID: 8723087

Claim:
An electrical resistance carbon fiber heating lamp, comprising: a vacuum glass tube; a plurality of terminals provided in the vacuum glass tube that supplies electrical power from outside the vacuum glass tube; and a carbon fiber heating element provided in the vacuum glass tube connected to the plurality of terminals that receives electrical power from the plurality of terminals and made by a process comprising: knitting a singular tubular member by intermeshing a plurality of carbon fibers and a plurality of general fibers in turn into the singular tubular member, wherein the singular tubular member comprises a plurality of first carbon fibers, a plurality of first general fibers, a plurality of second carbon fibers that extends perpendicular to the plurality of first carbon fibers and the plurality first general fibers, and a plurality of second general fibers that extends perpendicular to the plurality of first carbon fibers and the plurality of first general fibers; and burning away only the plurality of first general fibers and the plurality of second general fibers of the knitted singular tubular member to make the singular tubular member a tubular netting of the plurality of first carbon fibers and the plurality of second carbon fibers to form the carbon fiber heating element, wherein the singular tubular member further includes a plurality of holes made by the burning away of the plurality of first general fibers and the plurality of second general fibers of the knitted singular tubular member, wherein the plurality of first carbon fibers and the plurality of second carbon fibers are coupled by burning the plurality of first general fibers and the plurality of second general fibers, and wherein the intermeshed shape of the plurality of first carbon fibers and the plurality of second carbon fibers is maintained after the burning away of the plurality of first general fibers and the plurality of second general fibers of the knitted singular tubular member.
