The invention discloses a cold electron infrared ray lamp. The embodiment includes: a glass column, a plane cathode constituted by carbon film on a nickel base plate, a transparent conductive oxide layer on a glass base plate, a plane anode constituted by fluorescent coating on the conductive oxide layer, and a condensing lens. The cathode and anode are embedded into a groove of a base and then placed into the glass column. In addition, the condensing lens can be placed on the lens base of glass column. Apart from lens surface, the external surface of glass column is smeared with a reflectioncoating. Another embodiment includes a bar-shaped cathode, which is composed of nickel bars of carbon film on the half surface of the nickel bars; a curved surface anode comprises a metal reflection base plate smeared with fluorescent coating. The fluorescent coating can trigger fluorescent powder coating of infrared ray within the wave length of 700nm to 1,500nm. Lamp tubes produced with the invention have a longer service life than those heated electronic infrared lamps generated by the traditional tungsten filament heating, and are able to further enhance the lighting capability.
