INFRARED EMISSION LAMP USED FOR SENSOR OF GAS, CONCENTRATION DETECTOR OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To provide an infrared emission lamp formed into a simple and small lamp structure having high infrared emissivity and used for a sensor of gas, a concentration detector or the like. SOLUTION: This infrared emission lamp is so structured that a ceramic thin film 5 is formed by thermal spraying ceramic powder 4 having high infrared emissivity on a glass surface of a head part 1a of a lamp body 1 formed into a small glass bulb filled with gas 3 with a filament 2 disposed, the upper surface of the thin film 5 is coated with one layer of a titanium oxide solution 6 to dispose an infrared emitting double coating part 8 as a whole, and an infrared ray in a long wavelength region such as an infrared emission wavelength of 5-6μm is emitted by the use of infrared emission from the filament of the lamp body and infrared emission from the coating part 8 directly heated by using heat generated by the lamp itself as a heat source.
