Abstract
Abstract A lighting system for homes and the like comprising a voltage source, a plurality of lamps at various locations, a time interval relay for connecting the lamps to the voltage source for a predetermined time interval, and control switch means connected to the voltage source for selective energization of the time interval relay from an entranceway to light the corridors and other areas in the home to allow an individual sufficient time to walk through such areas before the lights turn off.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
96 words
An interior lighting system for buildings, said system comprising a voltage source, a time interval relay including a solenoid and a set of main normally opened contacts operatively connected to said solenoid for closure upon energization of the solenoid, at least one momentary control switch located in said building, and a plurality of parallel connected lamps each connected in parallel with said voltage source when said main contacts are closed, said control switch including a set of control contacts serially connected to said solenoid, whereby momentary closure of said control contacts effects actuation of said solenoid.
