Title: Spotlight unit
Inventor: TANAKA HIROYUKI
IPC: F21S10/00
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To enhance the efficiency of a positioning work, and improve the reliability of control by making slave spotlights follow the swing drive of a master spot light by a controller unit. SOLUTION: When a master spotlight SL1 is remotely operated and is swing- driven, the spotlight SL1 detects a drive angle by a swing drive, and outputs the same to a controller unit CU as a position detection signal. Based on the position detection signal, the unit CU outputs drive control signals to respective slave spotlights SL2 to SLn. Based on the drive control signals, the respective slave spotlight drive control portions DR2 to DRn control the swing drives so that the spotlight radiation directions follow the radiation direction of the spotlight SL1. Thereby, all the spotlight radiation directions can be controlled by only the radiation direction control of the spotlight SL1 so that the radiation direction control can be conducted quickly and easily.
