LAMP HAVING LIGHT EMITTING AND HEAT GENERATING FUNCTIONS THROUGH INFRARED AMPLIFICATION CAPABLE OF IMPROVING ENERGY EFFICIENCY

摘要

PURPOSE: A lamp is provided to achieve improved energy efficiency by permitting a heat source to generate heat at a low temperature, and prevent blackening by permitting the heat source to be separated from a light emitting portion. CONSTITUTION: A lamp(100) comprises an infrared radiating unit(110) having an infrared radiating member arranged in the infrared radiating unit, wherein the infrared radiating member has both ends connected to lead wires fixed at a compression sealing portion of an inner quartz glass tube such that the inside of the infrared radiating unit is vacuum sealed; and an outer quartz glass tube(121) having a compression sealing portion(122) where the lead wire led out from the compression sealing portion of the inner quartz glass tube is fixed and connected to the other lead wire. A resonance absorbing material is injected between the inner quartz glass tube and the outer quartz glass tube and sealed.
