Summary:A light source includes a base, a light-transmissive envelope coupled to the base and a heating element coupled to the base and positioned within the light-transmissive envelope. The heating element includes a first region and a second region arranged in a structure having a periodicity of distribution of between about 100 nm and about 1000 nm, in which the first region includes a first material selected from the group consisting of carbides of transition metals, nitrides of transition metals, borides of transition metals and oxides of transition metals.
