Abstract
The invention provides a quartz lamp used for a long-term ultra-high-temperature hot test. The quartz lamp comprises a quartz lamp tube and heating filaments, wherein a first cavity and a second cavity are formed in the quartz lamp tube; the heating filaments are arranged in the first cavity; and a cooling medium is pumped to the second cavity to cool the first cavity. The second cavity is used as the cooling medium channel, so that when the cooling medium flows, the heat can be taken away to cool the quartz lamp tube so as to prevent the quartz lamp tube from being damaged in a long-term ultra-high-temperature environment and to satisfy the heating requirement of the long-term ultra-high-temperature test.
