BULB TYPE HEATER AND LIGHTENING DEVICE

摘要

PROBLEM TO BE SOLVED: To attach/detach a bulb type heater in a single operation without requiring any special wiring for improving safety in attachment/detachment of the bulb type heater even in a high temperature condition. SOLUTION: For supplying electric power to a filament 13 sealed inside a quartz bulb 12 with radiation transparency, outer lead wires 181 and 182 are taken outside from the both ends via sealing end parts 151 and 152. The sealing end parts 151 and 152 and the outer lead wires 181 and 182 are supported freely movably in heat-resistant insulative base metals 191 and 192. Conductive metal pin terminals 221 and 222 to be connected electrically are fixed across the outer lead wires 181 and 182 inside the base metals 191 and 192. In installation to the socket, the pin terminals 221 and 222 are elastically and electrically supported. Attachment/detachment is carried out in a single operation, since an insulation property is provided to an installed part. COPYRIGHT: (C)2007,JPO&INPIT
