Title:
HALOGEN HEATER
Document Type and Number:
Japanese Patent JP2016072220
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a halogen heater which suppresses temperature reduction of a bulb that is positioned in a non-luminescent region.SOLUTION: A heater 1-1 includes a bulb 2, a filament 3, a gas 4 and metal bodies 51 and 52. The filament 3 is disposed along a tube axis inside of the bulb 2. The filament 3 includes a luminescent part 31 and non-luminescent parts 32 and 33. The luminescent part 31 emits light during electrification. The non-luminescent parts 32 and 33 are disposed in both ends of the luminescent part 31 in a tube axis direction, electrically connected with the luminescent part 31 and made non-luminescent relatively to the luminescent part 31 during electrification. The bulb 2 includes a luminescent region P1 and non-luminescent regions P2 and P3. In the luminescent region P1, the luminescent part 31 is disposed. In the non-luminescent regions P2 and P3, the non-luminescent parts 32 and 33 are disposed. The metal bodies 51 and 52 are disposed inside of the bulb 2. The metal bodies 51 and 52 are capable of conducting heat. The metal bodies 51 and 52 are disposed in the non-luminescent regions P2 and P3.SELECTED DRAWING: Figure 1
