DIMMING CONTROL DEVICE OF A FLUORESCENT LAMP, CAPABLE OF MAINTAINING THE LIFESPAN OF A STABILIZER AND A LAMP DUE TO LOW TEMPERATURE

摘要

PURPOSE: A dimming control device of a fluorescent lamp is provided to have an energy saving function and a sensor lamp function by controlling the illuminance of a fluorescent lamp through a stabilizer controller.;CONSTITUTION: A human detection sensor unit(30) generates a control signal when a body is detected. When ambient temperature is less than a fixed temperature, a temperature sensor unit(40) generates the control signal. A signal processing unit(20) usually generates a lowest illumination signal. The signal processing unit generates a highest illumination signal according to the control signal of the human detection sensor unit and the temperature sensor unit. A dimming ballast(10) comprises a rectifier and a stabilizer controller. The stabilizer controller executes the dimming control of a fluorescent lamp according to the lowest illumination signal and the highest illumination signal of the signal processing unit.;COPYRIGHT KIPO 2011
