However, in the configuration described in Patent Document 1, the illuminance sensor receives the light reflected from the floor surface of the living room using the device, so when the color etc. of the floor surface of the living room is changed, Because the amount changes, control to brighten the main light is performed, and even if the set brightness is reached, the light received by the illuminance sensor is insufficient, and control to brighten the main light is performed, so the main light becomes too bright As a result, power consumption increases compared to when brightness is set, and energy saving may not be achieved.
An object of the present invention is to provide a lighting device that maintains a desired brightness in a living room even if the floor condition of the living room changes.

In order to solve the above-mentioned conventional subject, in the present invention, in the lighting device which has a main light, a sensor unit, and a control part in the present invention, the sensor unit has an illumination sensor and detects ambient illumination. The control unit compares the power consumption at the time of setting with the power consumption at the time of reaching the desired brightness when recognizing that the required brightness has been reached, and when the latter consumes more power, the consumption at the time of setting It is characterized in that the brightness of the main light is controlled so as to be equal to the power, and the light quantity received by the illumination sensor at that time is reset to the newly obtained brightness.

ADVANTAGE OF THE INVENTION According to this invention, provision of the illuminating device which maintains the brightness in the living room for which it requests | requires is enabled also by the condition change of the floor surface of a living room.

An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an overall view of a lighting apparatus according to the present invention as viewed from the floor side. As shown in FIG. 1, the lighting device body 1 comprises a main light body and a light transmitting cover 2 covering it from the lower side. In addition, a sensor unit 4 mounted on the periphery of the lighting device body 1 is provided. The sensor unit 4 comprises a sensor unit body and an illumination sensor. In addition, a decoration board portion 3 is provided around the lighting device body 1. The sensor unit 4 is provided so as to be on the ceiling side with respect to the decorative gutter plate 3.
A control circuit (not shown) is incorporated in the lighting device body 1 and operates by supplying commercial power. Also, a sensor unit is connected to the control board by wiring (not shown).

  Next, a functional example of the illumination system (illumination device) in the present embodiment will be described with reference to FIG.

  The overall control of the lighting device body 1 is performed by the microprocessor 23. By executing the program in the microprocessor 23, various functions are embodied.

  A transmission signal from the remote control transmitter is received by the remote control reception circuit 21 and a signal is sent to the microprocessor 23. Based on this transmission signal, the microprocessor 23 operates a main lamp (first light source) drive circuit 41 which is a drive circuit of the main lamp (first light source) 10 and a safety light drive circuit 42 which is a drive circuit of the safety light 11. The light source is controlled to turn on / off or dim according to the transmission signal.

  Further, an illuminance detection circuit 43, an illuminance sensor 30, and a non-volatile memory 44 are connected to the control circuit. The lamp driver is composed of an inverter or the like.

  Also, the remote control transmitter (not shown) is provided with the "lighting button" and "lighting off" button of the main light, the "automatic light control button", and the "up button" and "down button" of the main light brightness. There is.

  The operation of the automatic light adjustment will be described based on the flowcharts of FIGS. 3 and 4. The flowchart of FIG. 3 shows the setting value setting of light adjustment before automatic light adjustment and the start of automatic light adjustment.

  Set the light control value according to the following procedure.

  First, the remote control transmitter is used to set a desired light control state. Subsequently, the user continues pressing the "automatic light control" button of the remote control for a predetermined time (about 3 seconds in the embodiment) (first predetermined operation).

  After that, the control unit reads the output value of the illuminance sensor and sets the illuminance to be adjusted automatically (setting value a). This setting is stored in the non-volatile memory of the control unit (first control operation). Further, the power consumption is calculated from the output amount from the microprocessor 23 to the main lamp drive circuit 41, and the result is stored as the power consumption c (first power consumption) in the non-volatile memory of the control unit (second control operation ). At the time of setting, the buzzer is informed by increasing the number of times of ringing from the time of normal reception. The mode is set to the automatic light adjustment mode (first state).

  When the above setting is performed, since the setting value is recorded in the non-volatile memory, the setting after the next time is unnecessary, and the mode is set to the automatic light control mode only by pressing the “automatic light control” button.

  The control for setting the automatic light adjustment mode is a fourth control operation.

  The flowchart of FIG. 4 shows the operation of the automatic light adjustment mode.

  The operation of the automatic light adjustment mode is as follows.

The illuminance sensor 30 takes in illuminance at intervals of a predetermined time T1 (captured value b).
The lighted state is adjusted as follows by comparing the taken value b with the set value a (third control operation). Here, when a> b, it is too bright than the set value, so the light output is reduced (third control operation). When a <b, it is too dark, so the light output is increased (third control operation). When a = b, it is as set. At this time, the power consumption d (second power consumption) is obtained from the amount of output from the microprocessor 23 to the main lamp drive circuit 41 (fifth control operation). If the power consumption d is larger than the power consumption c, the light output is reduced so that the power consumption d becomes the power consumption c (sixth control operation). When the power consumption b and the power consumption c become equal, the output value e of the illuminance sensor is read, the value is reset as a new set value a, and stored in the non-volatile memory (seventh control operation). Repeat the above operation.

  That is, in the illumination device having the main light, the sensor unit, and the control unit, the sensor unit has an illuminance sensor, and when detecting the ambient illuminance, the control unit has reached the required brightness. The power consumption at the time of setting is compared with the power consumption at the time when the required brightness is reached. If the latter consumes more power, the brightness of the main light is equal to the power consumption at the time of setting At that time, the light amount received by the illuminance sensor is reset as newly obtained brightness.

  According to the items described in the present embodiment, it is possible to provide a lighting device that maintains the brightness of the room that is sought even when the floor surface of the room changes.
