INFRARED LIGHT BULB, HEATING DEVICE, PRODUCTION METHOD FOR INFRARED LIGHT BULB

摘要

An infrared light bulb having a desired radiation power distribution by forming a reflection film on a glass tube of a basic infrared light bulb, heating device using the infrared light bulb, and a production method for the infrared light bulb, the basic infrared light bulb being constituted by forming grooves at the opposite ends of a solid, platy heating element consisting of a carbon-based substance, by applying an adhesive of a carbon-based substance to a region including the grooves, and by inserting an end of the heating element into a slit formed in the end of a high-conductive radiation block and holding the element therein.
