Title:
ULTRAVIOLET LAMP
Document Type and Number:
WIPO Patent Application WO/2020/232783
Kind Code:
A1
Abstract:
Provided is an ultraviolet lamp (100). The ultraviolet lamp comprises: a lamp tube (110) and electrodes (120). A discharging cavity (140) is arranged in the lamp tube (110), a thermistor (160) is arranged at a sealing endcap (152) on a first end of the lamp tube (110), the sealing endcap (152) is provided with an accommodating groove (151) communicating with the discharging cavity (140), amalgam (150) is stored in the accommodating groove (151), the thermistor (160) heats the amalgam (150) stored in the accommodating groove (151) at the sealing endcap (152), and the Curie temperature of the thermistor (160) is in the range of [T1+(T2-T1)/5] to [T1+4*(T2-T1)/5], wherein T1 and T2 are respectively the lowest working temperature and the highest working temperature of the amalgam (150) when an input power of the ultraviolet lamp (100) is 100% and an ultraviolet radiation power is in a continuous area of from 90% to 100%. The ultraviolet lamp (100) can maintain a high ultraviolet radiation efficiency under a relatively wide environment temperature range and a relatively wide power output range, and the cost thereof is relatively low.
