1. Description
Sixteen flourescent tubes provide the lighting for the passenger compartment, thirteen for the seating area, one for the lavatory and two for the entrances(aft).
Ballast control, essential to the operation of the flourescent tubes, is employed to connect a 28V d.c. input into an alternating current in excess of 350 volts at 38 KHZ or greater.
Three ROOF LIGHTS switches, panel 12P, provide the control for the passenger compartment lighting. They are three position switches which provide an OFF/DIM/BRT (bright) facility. The RIGHT switch controls seven right forward tubes. The ENTRANCE switch controls the two aft tubes and the LEFT switch controls the six left forward tubes.
The lavatory light is controlled by a microswitch in conjunction with the compartment door lock. No dimming facility is available. The door lock microswitch also controls the LAVATORY OCCUPIED passenger sign. A lavatory compartment facility light is also provided.
2. Operation
With electrical power supplied and circuit breakers 126, 127 and 128 closed on 3D panel, the forward seven right and six left, passenger compartment lights may be switched on by separate switches.
The aft two of the 15 passenger compartment lights are separately switched as entrance lights. Each of the three switches has a BRT (bright) and DIM facility which can be selected for the respective flourescent tubes. With C/B 127 closed the lavatory compartment utility light is permanently lit. Locking the lavatory door closes a microswitch which switches on the lavatory compartment flourescent tube and the LAVATORY OCCUPIED sign. There is no dimming facility for either the lavatory compartment utility light or the flourescent tube.

(c) Control afforded by selection of the EMERGENCY PASSENGER COMPARTMENT LIGHTS switch to ARMED.
Prior to engine start, with the pilots EMERGENCY PASSENGER COMPARTMENT LIGHTS switch set to ARMED, relay LM20 on panel 30C will be energized via relays P and CK on panel 2C, ensuring that the emergency lighting does not illuminate. After the generators come on line, relay P latches, breaking the supply to the coil of relay LM20. Simultaneously, relays S and Z on panel 2C energize, reconnecting the supply. During the switching period, a capacitor across the coil of relay LM20 ensures the relay does not de-energize and the emergency lighting remains extinguished.
In flight, after a right system generator failure, the emergency lighting, as described in para (b) will illuminate due to the loss of the GROUND SERVICES busbar.
In the event of a double generator failure on the ground, the emergency lighting will illuminate, due to the latching action of relay P which isolates the coil of the relay.
