2. Description of the Related Art FIG. 9 is a schematic structural view of a first conventional example according to the present invention, and FIG.
0, a block diagram is shown in FIG. 11, and an operation flowchart is shown in FIG.

In this conventional example, the reflected light from the floor is detected by a brightness sensor 13 provided in the control unit 3 and provided in the control unit 3 so that the detection output value of the brightness sensor 13 becomes substantially constant. A lighting control signal S1 is sent from the provided fixture control unit 15 to a ballast 16 provided in the lighting fixture 4, and the lighting fixture 4 is transmitted.
The feedback control is performed on the light output of the lamp 17 provided in the controller. In this conventional example, a remote control signal 12 from a remote control (hereinafter referred to as a remote control) 5 is provided.
Is received by the remote control receiver 2 provided in the control unit 3, and the control target value of the brightness sensor 13 can be set.

I do. Upon transition to each setting mode, the process exits from the normal feedback control mode. If the setting mode signal is a signal that changes brightness, the brightness is adjusted by increasing / decreasing the dimming level. When the adjustment is completed, the value of the brightness sensor 13 at the time of completion of the adjustment is stored as a control target value by a storage signal, and the feedback control is performed so that the stored, that is, the set control target value of the brightness sensor 13 becomes substantially constant.

The current operation mode is indicated by a triangle in FIG. In addition to the display unit 8, the remote controller 5 is provided with switches 9 and 10 for light control UP, light control DOWN, mode selection, storage, transmission, and confirmation. Works like Dimming UP: Outputs a signal that increases the dimming level. Dimming DOWN: Outputs a signal that lowers the dimming level. Mode selection: During setting, each item of the brightness sensor, the dimming upper limit, and the dimming lower limit is selected on the display unit 8. Memory: Outputs a memory signal. Transmission: Outputs a signal that causes the appliance to enter the operation mode selected by the mode selection switch. Confirmation: Output confirmation signal.

The operation will be briefly described below with reference to FIGS.

When a remote control signal 12 is input from the remote control 5 and the remote control signal 12 is a setting mode signal, the mode shifts to each setting mode (mode for setting brightness, dimming upper limit, dimming lower limit, etc.). I do. Upon transition to each setting mode, the process exits from the normal feedback control mode. When the setting mode signal is a signal for changing brightness, the brightness is adjusted by increasing / decreasing the dimming level. When the adjustment is completed, the value of the brightness sensor 13 at the time of completion of the adjustment is stored as a control target value by the storage signal as the remote control signal 12, and the stored (set) control target value of the brightness sensor 13 is stored.

It is omitted here. The difference from the second conventional example is that a second setting mode (hereinafter, referred to as a setting mode) that can be set during the normal mode is provided. The description is omitted by attaching the same reference numerals.

Here, the main setting modes are shown below. 1) Manual dimming mode: The dimming level is up / down regardless of the feedback control by the brightness sensor 13.
Then, dimming is performed manually. The remote control code in that case is UP / DOWN. 2) Brightness sensor value setting mode: The value of the brightness sensor 13 in the normal mode is set.

/ Down to adjust the brightness. The setting mode signal is the brightness sensor value setting mode signal (remote control code is C
In the case of (NT-UP / CNT-DOWN), the mode shifts to the brightness sensor value setting mode, and in this mode, the brightness is adjusted by changing the dimming level up / down. If the setting mode signal is a signal of the brightness sensor value fine adjustment mode, the brightness sensor value fine adjustment mode (the remote control code is A-
(UP / A-DOWN), and in this mode, the dimming level is up / down to adjust the brightness.

When the adjustment is completed in each setting mode, the value of the brightness sensor 13 at the time when the adjustment is completed is stored by the storage signal as the remote control signal 12, and the signal for transition to the normal mode (the remote control code is SENSA) Is transmitted to shift to the normal mode in which feedback control is performed so that the stored control target value of the brightness sensor 13 is obtained.

On the other hand, while the adjustment is not completed in each setting mode, a signal for shifting to the normal mode (the remote control code is SENS
After transmitting A), the mode shifts to the normal mode in which the feedback control is performed so that the control target value of the brightness sensor 13 before the setting mode is entered.

With the above-described configuration, the brightness sensor 1 can be transmitted only by transmitting the storage signal as the remote control signal 12.
The control target value of No. 3 can be stored and the mode can be shifted to the normal mode. That is, the transmission button is not required on the remote controller 5, the operability of the remote controller 5 is improved, and the remote controller 5 can be downsized. .

When an error occurs during each setting mode, the apparatus shifts to the error mode. When the mode shifts to the error mode, the lighting fixture 4 is fully lit or blinks,
Alternatively, the operator is informed that the mode has shifted to the error mode by turning on a notifying means such as a separately arranged LED. When it is desired to confirm the contents of the error, the remote controller 5 transmits a confirmation signal to confirm the type of the ballast 16 to the appliance side. The error information is returned by a reply signal from the appliance side that has received the confirmation signal, and the returned information is displayed on the display unit 8 to confirm the error state of the appliance. The content of the reply signal can store 256 bits of information except for the header and the footer. For example, when about 10 types of stabilizers 16 can be applied to the present device, 8 bits of the data are used for the data portion. The remaining 248-bit area is left. By using the surplus area as an error code, it is not necessary to newly provide a remote control code for an error, and the remote control code can be used effectively.
