The present invention relates to a filament for an infrared ray lamp used as a heater for industrial drying equipment or the like, and a method for manufacturing the filament, which involves coating a graphite thin film with a silicon-based coating solution to manufacture the filament of the infrared ray lamp. The thus-manufactured filament and the infrared ray lamp using the filament emit infrared rays in a uniform manner, improve ray emission efficiency, heat resistance, and durability, reduce power consumption, enable easy manufacture, and increase productivity. Further, the infrared ray lamp of the present invention has a centering coil for supporting and fixing the filament, and an insulator with an improved structure. In addition, a reflection film is arranged on the upper portion of the infrared ray lamp to improve the performance of the lamp.

La présente invention concerne un filament pour une lampe à rayons infrarouges utilisée comme un réchauffeur pour un équipement de séchage industriel ou similaire et un procédé de fabrication du filament, qui consiste à recouvrir une pellicule mince de graphite avec une solution de revêtement à base de silicium pour fabriquer le filament de la lampe à rayons infrarouges. Le filament ainsi fabriqué et la lampe à rayons infrarouges utilisant le filament émettent des rayons infrarouges de manière uniforme, améliorent le rendement d'émission des rayons, la résistance à la chaleur et la longévité, réduisent la consommation, permettent une fabrication facile et augmentent la productivité. En outre, la lampe à rayons infrarouges selon la présente invention comporte une bobine de centrage permettant de supporter et de fixer le filament, et un isolant à structure améliorée. De plus, une pellicule de réflexion est disposée sur la partie supérieure de la lampe à rayons infrarouges pour améliorer les performances de la lampe.
