SECONDARY CURRENT CONTROL DEVICE FOR FLOODLIGHT TRANSFORMER

PURPOSE: To ensure a prescribed luminous intensity or life in a floodlight even when the load from the floodlight side to the secondary side coil of a transformer is not constant every floodlight, or the load is fluctuated with the lapse of time, and surely provide such an effect without requiring a...

Zusammenfassung:	PURPOSE: To ensure a prescribed luminous intensity or life in a floodlight even when the load from the floodlight side to the secondary side coil of a transformer is not constant every floodlight, or the load is fluctuated with the lapse of time, and surely provide such an effect without requiring a complicated work. CONSTITUTION: This device has a detecting sensor 18 for detecting the value of the secondary current 12 of a transformer 10 supplied to a floodlight 6. It also has a control device 19 for inputting the detection signal of the detecting sensor 18, and increasing and decreasing the value of the primary current I1 of the transformer 10 so that the value of the secondary current I2 is a set value.
