the service life of the light changes, it is possible to use the electronic ballast - multifunctional filament heater power supply (a Multi - Function Filament - Heater Power Supply for an Electronic Ballast for went to long - the life and Dimmable Lamps)

摘要

in the invention, the filament heating power supply is the combination of forward and flyback type power converter, including a ballast control circuit, a power supply voltage in dc, brightness of the discharge lamp can be changed. uba58ud2b8 electric insulation to change as soon as possible the pressure of the delivery. the brightness control is the change in the action. the need is the best temperature to make the action of the filament voltage level control method in essence, and can prolong the service life. the filament heater power supply to the filament to control the positioning of the lead, and the filament voltage to provide.the filament heater power supply is started, the operation is to help the horse. the pre heating can, in use of the lamp life is extended, and the starting pulse voltage is empty in the terminal equipment or not. in the rain, there is whether to have the.
