Abstract

PURPOSE:To enable illuminance proper at all times to be secured by equipping an illuminance compensating value arithmetic unit which operates an illuminance compensating value according to the lapse of time, and a light adjusting control terminal which compensates and sends out a light adjusting control signal based on the illuminance compensating value. CONSTITUTION:An illuminance compensating value arithmetic unit 8 is equipped with a memory 82 which stored a luminous flux lowering characteristic attendant upon the lapse of time for every instrument, a memory 83 which stored luminous flux lowering characteristic by the advancing dirt according to instruments, and an operating means 84 which operates illuminance compensation value to maintain respective initial illuminance whenever the output value of a timer means 81 changes by the specified amount and adds both compensation values to output. A light adjusting control terminal 2a inputs light adjusting data transmitted from a transmission line 71 and compensates a light adjusting control signal to send out. Hereby, illuminance proper at all times can be secured without changing the setting value of an operation device.
