Abstract

PURPOSE: To secure the lamp test including the driving circuit which drives the lamps by turning on or off all at once the lamps to be tested with the driving circuit.
CONSTITUTION: When processor 7 is run by the program of the lamp test memorized in memory 8, the data of input circuit 10 is transferred to driving circuit 3 via processor 7. At this moment, circuit 3 is driven to turn on or off all at once lamps 1-1W1-n by turning on or off of switch 9. Here if some faulty lamp exists, the trouble is decided for the circuit system. As a result, the lamp test is possible including the driving circuit which drives the lamps.
