Description

  The present invention relates to an illumination lighting device, an illumination fixture, and an illumination system that connect an external device such as a human body detection sensor, an illuminance sensor, and a dimmer to control lighting and extinction of a light source and dimming.

  Conventionally, there is known an illumination system that uses a human body detection sensor to turn on at high illuminance when it is detected that there is a person and to turn on or off at low illuminance when it is detected that there is no person ( For example, see Patent Document 1).

  FIG. 7 is a diagram showing a schematic configuration of such an illumination system. In the figure, a signal indicating the presence or absence of a person detected by the human body detection sensor 31 is sent to the sensor control block 32. For example, as shown in FIG. 8, the signal indicating the presence / absence of a person is a pulse signal of an H level when a person is detected and an L level when no person is detected, and the sensor control block 32 inputs these signals. By doing so, for example, a dimming signal that has been subjected to pulse width modulation (PWM) as shown in FIG. 9 is output to the illumination lighting device 33 such as an electronic ballast.

  When a person is detected, as shown in FIG. 9A, a 5% duty PWM signal for fully lighting the discharge lamp 34 is output to the illumination lighting device 33, and when no person is detected, FIG. ) And (c), a PWM signal with a duty of 100% for turning off the discharge lamp 34 or a PWM signal with a duty of 85% for lighting at low illuminance is output to the illumination lighting device 33.

  The sensor control block 32 also sets the lighting holding time after detecting a person, and does not turn off the discharge lamp 34 immediately after the person is gone. For example, as shown in FIG. Control to maintain. This is because, for example, in a lighting system such as a staircase, if the light is turned off immediately after no more people are detected, it may be difficult to move up and down the staircase.

  In addition, there is an illumination system that detects the ambient brightness due to daylight using an illuminance sensor and automatically controls the lighting fixture to an appropriate amount of light according to the detected brightness. In this illumination system, when the outdoor is bright, it is lit at low illuminance, and when it is dark, it is lit at high illuminance, so that an illumination environment with constant brightness is always obtained (for example, Patent Documents 1 and 2). reference).

  FIG. 11 is a diagram illustrating a schematic configuration of an illumination system using an illuminance sensor. In the figure, a brightness signal detected by the illuminance sensor 41, for example, as shown in FIGS. 12 (a) and 12 (b), a DC signal of 5V is sent to the sensor control block 42 when bright and 1V when dark. To do. The sensor control block 42 outputs, for example, a PWM dimming signal as shown in FIG. 13 to the illumination lighting device 43 according to the signal input from the illuminance sensor 41.

  When the illuminance sensor 41 detects that the ambient brightness is dark, as shown in FIG. 13A, a PWM signal with a duty of 5% for fully lighting the discharge lamp 34 is output to the illumination lighting device 43 to be bright. Is detected, the PWM signal with a duty of 85% is output to the illumination lighting device 43 to adjust the light, and the light output of the discharge lamp 34 is reduced. Thereby, according to the ambient brightness detected by the illuminance sensor 41, for example, as shown in FIG. 14, the spatial illuminance can be controlled to be substantially constant regardless of day and night. Further, the illuminance of the spatial illuminance to be controlled can be changed by arbitrarily adjusting the relationship between the output signal of the illuminance sensor 41 and the dimming signal of the sensor control block 42.

  Furthermore, there is an example of a dimmer that outputs a PWM signal to the illumination lighting device in order to arbitrarily adjust the brightness of the illumination environment.

  FIG. 15 is a diagram illustrating a schematic configuration of an illumination system that controls the brightness of an illumination environment using a dimmer. In the figure, the PWM signal output from the dimmer 51 is input to the illumination lighting device 53. For example, when the on-duty ratio of the PWM signal is small as shown in FIG. 16 (a), the illumination lighting device 53 increases the light output of the discharge lamp 34 and turns on as shown in FIG. 16 (b). When the duty ratio is large, the illumination lighting device 53 decreases the light output of the discharge lamp 34. Further, as shown in FIG. 16C, when the on-duty ratio is 100%, the illumination lighting device 53 turns off the discharge lamp 34. In this manner, a person can adjust the volume of the dimmer 51 and change the duty ratio of the PWM signal output from the dimmer 51 to obtain a desired illuminance.

  As described above, in conventional illumination systems that use external devices such as human body detection sensors, illuminance sensors, and dimmers, the signal form and illumination control such as lighting, dimming, and extinction are different. In general, the control blocks are provided separately.

  However, providing a separate sensor control block for each external device increases the cost and causes a problem of poor versatility.

(First embodiment)
FIG. 1 is a diagram showing a schematic configuration of an illumination system according to the first embodiment of the present invention.

  In FIG. 1, the illumination system 1 of the present embodiment includes an illumination lighting device 11, an external device 12 connected to the illumination lighting device 11, and a discharge lamp 13 that is turned on when power is supplied from the illumination lighting device 11. It is the composition which has.

  The half-bridge inverter circuit 114 is a half-bridge type inverter circuit in which a series circuit composed of switching elements is connected between both ends of a smoothing capacitor. When the switching elements are alternately turned on and off, the chopper voltage Vdc is switched, and the high-frequency Convert to the square wave voltage.

  The LC resonance circuit 115 generates a substantially sinusoidal voltage by a resonance action by inputting a rectangular wave voltage from the half-bridge inverter circuit 114.

  The human body detection sensor 121 detects the presence / absence of a person using infrared rays emitted from the human body, and outputs a lighting operation control signal of H level or L level to the input signal processing unit 119 of the lighting device 11.

  The illuminance sensor 122 detects ambient brightness due to daylight, and outputs a lighting operation control signal having a DC voltage of 0 to 5 V to the input signal processing unit 119 of the lighting device 11 according to the detected brightness.

  The dimmer 123 outputs a PWM signal having a constant frequency to the input signal processing unit 119 of the illumination lighting device 11 in order to arbitrarily control the brightness of the illumination environment.

  The input signal processing unit 119 performs signal processing corresponding to the human body detection sensor 221 of the input lighting operation control signal. If the signal is 0V, the discharge lamp 13 is turned off. If the signal is 5V or more, the discharge lamp is discharged. An output control signal for lighting 13 is output to the inverter control unit 118. Further, the lighting holding time after detecting the presence of a person and turning on and detecting the absence of a person is set and output to the inverter control unit 118 (step S110).

  FIG. 6A is a diagram illustrating a state in which the discharge lamp 13 is turned off or turned on according to the low signal and the high signal of the input lighting operation control signal. As shown in the figure, if the low signal is 0V, the level of the output control signal and the output level of the electronic ballast are set to 0, the discharge lamp 13 is turned off, and if the signal is 5V or higher, the output control signal And the electronic ballast is fully output and the discharge lamp 13 is turned on.

  FIG. 6B shows a state in which the discharge lamp 13 is turned on when a person is detected, and when the person is no longer detected, the lighting holding time is set in the input signal processing unit 119 and the lighting is continued. ing.
