Martin's invention "is applicable for use in electric-lighting apparatus of various kinds, but it is shown as embodied in an apparatus or system in which the candle or illuminating device consists of a portion of an electric circuit having less conductivity than the remainder of the circuit, and which becomes heated to a point of incandescence by the resistance offered to the passage of the electric current."
