Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a remote control device for a lighting load, and more particularly, to adjustment of a dimming signal output from a dimming section.

(Prior Art) In a lighting load remote control device, an operating device and a plurality of terminal devices are connected by a common transmission line, and a plurality of lighting loads are connected to each terminal device, and,
Control signals are sent from the operating device via a transmission line, including a start signal, an address signal specifying an arbitrary terminal, and mode signals such as several dimming signals or on/off signals preset in the operating device. The terminal device designated by the address signal controls the lighting state of the connected lighting load in accordance with the mode signal that is subsequently input.

(Problem to be Solved by the Invention) The value of the dimming signal output from the operating device to each terminal device is determined according to the purpose of the lighting load installed in different lighting areas such as a library, office, hallway, etc. However, even if the lighting load is set in advance to receive a certain average illuminance using a certain dimming signal, the illuminance of the lighting load used will decrease over time and the dimming signal will need to be revised. arise, and
When changing the use of one lighting area from, for example, a library to an office, the dimming signal also needs to be reset accordingly.

However, in such a remote control device for lighting loads, changing the dimming level of the dimming signal preset in the operating device requires changing the memory of the internal computer. It is not easy to change, and combined with the fact that the dimming signal is set digitally, it has the disadvantage that other analog adjustments cannot be made. Moreover, due to their nature, dimming signals require a large amount of storage capacity, and as a result, the capacity of the computer installed in the main operation panel is also large in order to set many dimming signals in advance. Transmitting an optical signal as a mode signal requires a large amount of time for transmission, and has the disadvantage that if there are a large number of terminals to be controlled, they cannot be controlled quickly.

In addition, for example, in the case of a device in which a dimmer unit that outputs a dimmer signal for each terminal device is installed, the adjustment must be made individually, and furthermore, each dimmer unit
For example, dimming signals are often set at fixed ratios such as 100% dimming, 70% dimming, and 40% dimming, and the adjustment work is also inefficient.

The present invention has been made in view of the above points,
By reducing the capacity of the control signal transmitted from the operating device to the terminal device in each lighting area, the capacity of the computer etc. installed in the operating device can be reduced, and the transmission speed of the control signal can be improved, and furthermore, each lighting area can be It is an object of the present invention to provide a remote control device that enables easy analog adjustment of a dimming signal lever that controls the lighting state of a lighting load for each area and has good control characteristics.
