Abstract: Disclosed herein is a circuit assembly comprising a light-emitting diode (LED) load in combination with a filament bulb simulation circuit, the filament bulb simulation circuit being configured to simulate a load that would be presented to a monitoring system by a filament bulb. In this manner, a filament bulb can be effectively replaced with one or more LEDs and thereby achieve power consumption savings. Also disclosed is a method for monitoring an LED circuit assembly with a monitoring system to determine whether the LED circuit assembly is deemed operational.

Abstract: An LED-based lamp assembly or diode lamp assembly effectively replaces a filament or incandescent type lamp assembly for cabin/compartment reading light applications for reducing power consumption and improving fuel efficiency. The diode lamp assembly comprises a light-emitting diode in circuit with peripheral components for effecting or simulating a low resistance through the diode lamp assembly. The simulation of a low resistance via the diode lamp assembly appears the same as the normal operation of a filament lamp assembly to existent circuit polling mechanisms so that the latter need not be replaced. Rather, the targeted element to be replaced is a relatively high power consumption filament lamp. A lamp monitoring method is further disclosed as bootstrap-supported by the teaching of the diode lamp assembly.
