When multiple people are having a chat.

The load pattern of lighting, etc. is changed according to each situation, such as turning on all the ceiling lights to make it brighter, turning on the jump rear lights when guests come, and turning on only the wall lights when people are taking a rest.

Normally, such load patterns can be switched by ON-OFF control of the switches of each load according to the respective situations, but this is troublesome as it is necessary to go to the location where each switch is set and operate the switch. In particular, in BSVA theaters and various conference halls, there are many sets of lighting loads, and in places with large equipment areas, it is difficult to control the combination of multiple loads. A method is adopted in which the information is input into a microcomputer, etc., and this is automatically controlled.

A load pattern control device was constructed by a switching section connected to the sequence control section and the remote control section and having a changeover switch for switching between automatic operation and remote control operation.

(5) Effects In this load pattern control device, by setting the changeover switch of the control section to the sequence control side, the load pattern set in advance is driven and controlled by sequential automatic switching, and if necessary, the load pattern that has been set is controlled by remote control. The drive can be controlled by manually selecting a pattern.

In addition, the setting sections for setting the load pattern are arranged in a matrix in correspondence with the display section, and the setting can be easily changed by operating the setting switch while looking at the display.
