Description

Technical Field

[0001] This utility model belongs to the field of power supply circuit technology, and specifically relates to an application in an ultraviolet lamp. Background Technology

[0002] Ultraviolet (UV) disinfection lamps are devices that use ultraviolet radiation to disinfect and sterilize air, water, and surfaces. UV disinfection lamps are mainly divided into UVC, UVB, and UVA bands. The UVC band has the strongest bactericidal effect, effectively destroying the DNA and RNA of microorganisms such as bacteria, viruses, and fungi, thereby achieving disinfection and sterilization. As a highly efficient and environmentally friendly disinfection device, UV disinfection lamps have continuously growing market demand, wide application areas, and significant development potential. Gas discharge lamps have high starting voltages and low discharge sustaining voltages. When the lamp is started with high voltage, the voltage drops and the current increases. If not controlled, the lamp current will continue to increase until the lamp burns out. Utility Model Content
