<p>PURPOSE:To effectively predict the lives of lighting electric lamps and efficiently support the maintenance plan of facilities by employing the weight function corresponding to the current values of lighting circuits in the lighting facilities controlling many electric lamps at the optional brightness. CONSTITUTION:Current values of multiple lighting circuits of a stage lighting facility are inputted from current signal input sections 1a-1n and recorded in a current record section 2 in time series. Lighting periods of electric lamps from the previous replacement timing inputted from a manual input action section 3 and recorded in a maintenance information record section 4 are processed by an arithmetic process section 6 based on the weight function corresponding to the current values of a weight function storage section 5 and recorded in a weighted lighting period record section 7. If the integrated value of the weighted lighting period of an electric lamp exceeds a preset fixed value, a message that the replacement timing of this electric lamp arrives is displayed on a display section 8. The maintenance plan of multiple lighting facilities can be efficiently supported.</p> |
