A vertical type lamp heater is provided reduce thermal impact of a carbon heating element by winding the carbon heating element around an insulating tube. A vertical tube lamp heater comprises a vacuum glass pipe(1), a lead line(2), a carbon heating element(3), and a connector(5). The lead line passes through both ends of the vacuum glass pipe, and the carbon heating element is connected to the lead line protruded to the both sides inside of the vacuum glass pipe. The connector connects the lead line and the external electrical wire(4) exposed to the outside of the vacuum glass pipe while being made of germanium or a yellow soil. The insulation tube(6) is inserted inside the vacuum glass pipe. The carbon heating element is spirally wounded around the insulation tube. |
