#CMT# #/CMT# The circuit has a resistor (R1) connected in series with a LED, and another resistor (R) for defining a display circuit control (A), whose one end is connected to an output of a bridge rectifier. The control controls product change from work status of a load of a halogen lamp (L) connected to an output transformer for permitting the LED to create light display under different conditions by changing excitation of voltage and amperage, while permitting control effects to offer effectiveness without affecting utilization of the transformer. #CMT#USE : #/CMT# Display circuit for an electronic transformer of a halogen lamp for indicating status of an overload, normal utilization or absence of electric supply. #CMT#ADVANTAGE : #/CMT# The display circuit control permits a user to judge origin of the failure for facilitating determination of cause of the breakdown, and preventing the transformer to be subjected to effects of temperature rise due to presence of the circuit. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram of a display circuit for an electronic transformer of a halogen lamp. A : Display circuit control C : Capacitor L : Halogen lamp R, R1 : Resistors T2 : Oscillation control winding. |
