Abstract
PURPOSE:To reduce cost by making possible the intensity regulation in several stages eliminating the need for any special ballast for intensity regulation in a power saving discharge lamp lighting apparatus which is designed to lower the illuminance with the lamp whenever the outside of the room becomes brighter by the solar beam. CONSTITUTION:The secondary coil 2b of a heater transformer 2 is connected to one end of a fluorescent lamp 1 while an impedance element 3 such as capacitor is connected between the secondary coils 2a and 2b. The lamp current is reduced according to the impedance value of the element for less illuminance by lamps. In a power saving fluorescent lamp of this type, an impedance circuit 6 is connected to the heat transfer 5 while a switching circuit 7 is connected to the circuit 6 to switch the impedance value in plural stages. A signal inputted to a line 9 is received with a receiver 8 to control the circuit 7.
