HEAT LAMP

摘要

PURPOSE: A carbon yarn heater lamp is provided to improve heating efficiency by winding a carbon heater around an outer circumference of an internal quartz tube spirally. CONSTITUTION: A carbon heater(6) is made by braiding the carbon yarn. The carbon heater is spirally wound around the outer circumference of an inner quartz tube(2). The inner quartz tube is inserted into an outer quartz tube(1). Both ends of the carbon heater are connected to an inner electrode(3) by a connection unit. The connection unit is connected in both ends of the inner quartz tube. The inner electrode is connected to an external electrode(5) by a connection piece(4). A presser(11) is formed in both ends of the outer quartz tube. The inner electrode and the outer electrode are connected in the presser by a connection piece.
