The lighting fixture includes a fixture body 30, a globe 32, a lighting load 3 as shown in FIG. 18, and lighting devices 1a and 1b for controlling lighting of the lighting load 3. The instrument body 30 is mainly composed of a light transmissive glove 32 and a light non-transmissive metal, and is installed at a height of about 1.8 m or more from the ground surface as shown in FIG. There are many cases.

  In such a lighting fixture, each of the sensors 15 and 17 and the remote control signal receiving unit 16 shown in FIG. 18 has the influence of the shadow on the globe 32 by the lighting device including them and the output light of the lighting load 3 are the sensors 15 and 17. In many cases, it is incorporated in the end side inside the instrument main body 30 in order to avoid the influence. When installed in such a state, the outer shell body 30 made of metal causes problems such as obstructing human detection, external illuminance changes, and reception of remote control signals.

  As described above, an increase in the functionality of a control method such as remote control has led to an improvement in user convenience. However, on the other hand, it leads to an increase in the number of signal lines inside the illuminating device. For example, this results in an increase in the size of the illuminating device, such as an increase in the area of the printed circuit board in the illuminating device and an increase in the number of signal line connectors. This further increases the size of the outer shape of the luminaire, and hinders downsizing and cost reduction for improving the workability and design of the luminaire. At the same time, problems such as interference with other signals such as the remote control signal becoming the noise source of the illuminance sensor signal increase, and the need for a filter function in terms of hardware and software for the input signal also increases. ing.

  The present invention has been made in view of such a reason, and an object of the present invention is to realize miniaturization by reducing the wiring in a lighting apparatus having a sensor and a remote control function.

  In order to solve the above problem, the invention of claim 1 is an analog input signal whose signal level continuously changes over time, as shown in FIG. 1, and a shorter period than the change of the analog input signal.

  According to a second aspect of the present invention, in the lighting device according to the first aspect, the analog input signal is an illuminance sensor signal that detects ambient illuminance, converts it into an electrical signal, and outputs an illuminance sensor signal to the control circuit unit 11. The digital input signal is a remote control signal of the remote control signal receiving unit 16 that receives the signal of the remote control transmitter 4 and outputs a signal to the control circuit unit 11, and the output of the illuminance sensor 15 on which the remote control signal is superimposed. A signal is supplied to the control circuit unit 11, and the control circuit unit 11 has a threshold value X for determining the brightness of the illuminance using the illuminance sensor signal and a threshold value Y for determining the input of the remote control signal. The threshold value Y for determining the input of the remote control signal is a negative side when the remote control signal is a negative logic signal and a positive side when the remote control signal is a positive logic signal with respect to the threshold value X for determining the brightness of the signal of the illuminance sensor 15. Is set, and characterized in that it is set outside the output range of the illuminance sensor signal (see FIG. 9 (c), FIG. 12 (c)).

  According to a third aspect of the present invention, in the lighting device according to the first aspect, the analog input signal is an illuminance sensor signal that detects ambient illuminance, converts it to an electrical signal, and outputs an illuminance sensor signal to the control circuit unit 11. The digital input signal is a human body detection sensor signal that detects and outputs a person, and the output signal of the illuminance sensor 15 on which the human body detection sensor signal is superimposed is supplied to the control circuit unit 11. , The threshold value X for determining the brightness / darkness of the illuminance using the illuminance sensor signal and the threshold value Z for determining the input of the human body detection sensor signal are respectively included, and the threshold value Z for the input determination of the human body detection sensor signal is The threshold X for determining the brightness of the signal of the illuminance sensor 15 is set to the negative side if the human body detection sensor signal is a negative logic signal, and to the positive side if the human body sensor signal is a positive logic signal, and the illuminance sensor signal Out of Characterized in that it is set outside the range (see Figure 13).

  According to a fourth aspect of the present invention, in the lighting device according to the first aspect, the analog input signal is an illuminance sensor signal that detects ambient illuminance, converts it to an electrical signal, and outputs an illuminance sensor signal to the control circuit unit 11. The digital input signal is a remote control signal of the remote control signal receiving unit 16 that receives the signal of the remote control transmitter 4 and outputs a signal to the control circuit unit 11, and a human body detection sensor signal that detects and outputs a person. The remote control signal is either a positive logic signal or a negative logic signal, the human body detection sensor signal is the other signal, and the output signal of the illuminance sensor 15 on which the remote control signal and the human body detection sensor signal are superimposed is Supplied to the control circuit unit 11, and the control circuit unit 11 determines the threshold value X for determining the brightness of the illuminance using the illuminance sensor signal and the input of the remote control signal. Threshold value Y for determining the input of the human body detection sensor signal and threshold value Z for determining the input of the human body detection sensor signal, respectively. With respect to the threshold value X, the negative logic signal is set to the negative side, the positive logic signal is set to the positive side, and each threshold value is set outside the output range of the illuminance sensor signal.

  The invention of claim 5 is a sensor or a lighting fixture with a remote control function, characterized in that the lighting device according to any one of claims 1 to 4 is used (see FIG. 3).

  According to the first aspect of the present invention, when the digital input signal is superimposed on the analog input signal input to the control circuit unit of the lighting device and the input value of the digital input signal is a positive logic signal, the maximum value of the analog input signal is obtained. In the case of a negative logic signal, since it is smaller than the minimum value of the analog input signal, the digital input signal is superimposed on the analog input signal and the two signals are combined into one signal without impairing the functions of each other. Can be processed. In addition, this makes it possible to reduce wiring, and to realize downsizing of the lighting device such as downsizing of the printed board and reduction of the number of connectors.

  Further, if the remote control signal uses infrared rays, the remote control signal becomes a noise source of the illuminance sensor signal depending on the filter characteristic of the illuminance sensor signal that is an analog input signal. The remote control signal input determination threshold is set to the negative side when the remote control signal is a negative logic signal, to the positive side when the remote control signal is a positive logic signal, with respect to the threshold value for determining the brightness of the signal of the illuminance sensor, and By setting the illuminance sensor signal outside the output range, it is not necessary to consider signal processing when it becomes a noise source, and further, wiring saving can be realized.

  Further, when the illumination load is turned on by the input of the human body detection sensor signal, the value of the illuminance sensor signal may not be accurately read due to the influence of the self-light on the illuminance sensor signal. The human body detection sensor signal input determination threshold is negative when the human body detection sensor signal is a negative logic signal and positive when the human body detection sensor signal is a positive logic signal. When the human body detection sensor signal is generated, the illuminance sensor signal is automatically ignored, and the influence of the self-light on the illuminance sensor is reduced. There is no need to think about it, and further, wiring saving can be realized.

  According to the invention of claim 4, two digital input signals of the remote control signal and the human body detection sensor signal can be simultaneously superimposed on the illuminance sensor that is an analog input signal, and the three signals can be reduced to one signal. it can.

Moreover, in a lighting apparatus having a lighting device having the function of an illuminance sensor and a lighting device for control connected to the illuminating device by a lead wire, for example, the lighting device having the function of an illuminance sensor is provided with an illuminance sensor and a remote control function. Even when the remote control signal is replaced with an illuminating device in which the illuminance sensor signal is superimposed, a change associated with an increase in the number of signal lines is not required, and a remote control function can be easily added. That is, it becomes easy to make the lighting fixture multifunctional.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a block diagram showing the configuration of the first embodiment of the present invention. The lighting device 1b connected to the power source 2 and the lighting load 3 and the lighting device 1a having a sensor or remote control reception function are connected by a lead wire 1c, and an analog signal and a digital signal are superimposed on the lead wire 1c. ing. The illumination device 1a includes an illuminance sensor 15 that outputs an analog signal, a remote control signal receiver 16 that outputs a digital signal, a human body detection sensor 17, and the like. As shown in FIG. 3, the illuminating devices 1a and 1b may be accommodated in the same instrument main body 30, or may be installed separately.

  The wall-mounted lighting fixture shown in FIG. 3 has a fixture main body 30 that is a metal shell, a lighting load 3 such as a fluorescent lamp, a socket portion 31, a globe 32 that transmits light, and a control circuit portion. The lighting device 1b includes a lighting device 1a including a remote control signal receiving unit and an illuminance sensor unit. The lighting device 1a and the lighting device 1b are connected by a lead wire 1c. A glove holder 33, an illuminance sensor hole 35, and a remote control signal hole 36 are provided at the lower end of the instrument body 30. In addition, when the human body sensor 17 is also mounted in the illuminating device 1a, as shown in FIG.3 (b), the hole part 37 for human body detection sensors is further provided.

  The instrument body 30 is made of a metal such as iron and is formed in a substantially hollow rectangular parallelepiped shape, and is installed at a height of about 1.8 m from the ground surface of the wall surface. The globe 32 is formed of a light transmissive material, and is fixed to the instrument body 30 by a holding portion 33 of the instrument body 30. The illumination load 3 is, for example, a fluorescent lamp, and is attached to a socket 31 attached to the instrument main body 30.

  The illuminating device 1a detects ambient illuminance, converts it into an electrical signal, receives an illuminance sensor 15 that outputs an illuminance sensor signal to the control circuit unit 11, and a signal from the remote control transmitter 4, and sends a remote control to the control circuit unit 11. The remote control signal receiving unit 16 outputs a signal. The lighting device 1a is fixed in the fixture body 30 with the surface exposed through holes 35 and 36 provided on the outer lower surface of the lighting fixture. Then, a signal in which the remote control signal (digital signal) is superimposed on the illuminance sensor signal (analog signal) is output in the lighting device 1a, and is transmitted to the lighting device 1b through the lead wire 1c. The lighting device 1b includes a control circuit unit 11 that controls a lighting state of the lighting load 3 using a signal input from the lead wire 1c, a load driving circuit unit 13 that drives the lighting load 3, and a control circuit unit 11 And a power supply unit 12 for supplying operation power to the setting unit 14.

  The lighting apparatus can switch the lighting mode by using the remote control transmitter 4. In the case of equipment installed outdoors, for example, the lighting mode is “sensor mode” that automatically turns on when dark and automatically turns off when it becomes bright, and “normal lighting mode” that can be switched on / off only with an indoor wall switch. Two modes can be selected.

  Next, an operation when a signal from the lighting device 1a is input to the lighting device 1b will be described by taking as an example a case where an illuminance sensor signal is input as an analog input signal and a remote control signal is input as a digital input signal.

  The illuminance sensor 15 of the lighting device 1a outputs light around the lighting device 1a as a current. As a characteristic of the photocurrent, the current is large when it is bright, and the current decreases as it becomes dark. However, it does not become zero, but has a constant current value as a dark current. In the circuit shown in FIG. 2, this current value is converted into a voltage value.

  The voltage Vx expressed as the output of the illuminance sensor 15 is defined by a value obtained by multiplying the photocurrent Ia and the bias current I1 by the resistance R2, and the photocurrent Ia increases, that is, the ambient illuminance of the lighting device 1a is As it rises, the voltage Vx also increases. However, due to the voltage division by the resistor R1 and the dark current of the photocurrent Ia, as shown in FIG. 4 (a), the upper limit value b and the lower limit value a of the illuminance sensor signal output are within the range of the control power supply voltage Vcc and the ground GND, respectively. Change within. Note that the change in the output voltage Vx follows the change in brightness in a cycle of 24 hours per day and changes gradually.

  On the other hand, the remote control signal is obtained by demodulating the modulated remote control transmitter signal in the remote control receiver 16, and the demodulated remote control signal has a short waveform with a total length of about 0.2 seconds. A square wave of a positive logic or negative logic signal according to the code rule of the remote control signal.

  The remote control signal is superimposed on the signal of the illuminance sensor 15 by connecting the output of the remote control receiver 16 to the signal line of the illuminance sensor 15 described above via the diode D1. Each waveform is shown in FIG. In FIG. 4, (a) is an illuminance sensor signal output, (b) is a remote control signal output, and (c) is a voltage obtained by superimposing the illuminance sensor signal and the remote control signal output.

  In the control circuit unit 11, if the input signal level does not exceed the threshold value Y of the remote control signal, the input signal is always regarded as the input of the illuminance sensor signal, and whether the threshold value X arbitrarily set is exceeded, Brightness / darkness determination of ambient illuminance is performed depending on whether it has exceeded. For example, in the control example of FIG. 5, if the voltage level of the input signal is smaller than the threshold value X for a certain period or longer, it is determined that the surrounding is dark, an illumination lighting signal is output, and the illumination load is output via the load driving circuit unit 13. 3 is lit.

  Conversely, if the input voltage level exceeds a threshold value X for a certain period or longer, it is determined that the surroundings are bright, the output of the illumination lighting signal is stopped, and the illumination is turned off.

  On the other hand, it is determined in the control circuit unit 11 whether the remote control signal is an arbitrary list of codes. First, in the control circuit unit 11, as shown in FIG. 6, if the input signal exceeds the threshold value Y of the remote control signal, the input signal is transferred to a code discrimination process as a remote control signal. When it is determined that no signal exceeding the threshold value Y of the remote control signal is input for a certain period after the threshold value Y of the remote control signal is finally exceeded, and no remote control signal is input, the process returns to the determination process as the input of the illuminance sensor 15. .

  In the control circuit unit 11, the brightness determination of the illuminance sensor 15 is not performed during the code determination process of the remote control signal. That is, in order to discriminate between the remote control signal and the illuminance sensor signal, the algorithm is such that the input signal is regarded as the remote control signal when the threshold value Y of the remote control signal is exceeded (FIG. 7).

  If the remote control signal and the illuminance sensor signal are to be controlled separately, when the remote control transmitter signal is input, depending on the filter characteristics of the illuminance sensor, the remote control transmitter signal becomes a noise source. As shown, the output of the illuminance sensor may be disturbed. In this case, a mask process that ignores the illuminance sensor signal is required when a remote control signal is input.

  On the other hand, if the remote control signal is superimposed on the illuminance sensor signal as in this embodiment, when the remote control signal is input, it is handled only as the remote control signal as shown in FIG. , The mask processing is not necessary.

  However, as shown in FIG. 9 (a), when the remote control signal is a positive logic signal and the threshold value Y of the remote control signal is smaller than the threshold value X of the illuminance sensor, if the ambient illuminance exceeds the threshold value Y, The transition from the state to the lit state can be made, but the transition from the lit state to the unlit state cannot be made. "

  Therefore, when the remote control signal is a positive logic signal, the threshold value Y of the remote control signal is always set to be larger than the threshold value X of the illuminance sensor, as shown in FIG.

  Even if the threshold value Y of the remote control signal is larger than the threshold value X of the illuminance sensor, if the ambient illuminance exceeds the threshold value Y of the remote control signal as long as it is within the output upper limit range of the illuminance sensor, the remote control signal No longer works. Therefore, the remote control signal is configured so that its output c is larger than the maximum output value b of the illuminance sensor, and the threshold value Y of the remote control signal at that time is the illuminance as shown in FIG. It is set outside the sensor signal output range.

  As shown in FIG. 10, the same applies when the remote control signal is a negative logic signal superimposed on the illuminance sensor signal, and the remote control signal has a circuit so that its output c is smaller than the minimum output value a of the illuminance sensor. (FIG. 11). Specifically, the polarity of the diode D1 in FIG. 11 is opposite to that in FIG. 2, and the output of the remote control receiver 16 is pulled down to the ground level GND, so that the output c of the remote control signal has illuminance. It becomes smaller than the minimum output value a of the sensor.

  At this time, if the threshold Y of the remote control signal is larger than the threshold X of the illuminance sensor as shown in FIG. The transition from the off state to the unlit state can be made, but the transition from the unlit state to the lit state cannot be made. "

  Therefore, the threshold value Y of the remote control signal is always set to be smaller than the threshold value X of the illuminance sensor, as shown in FIG. Further, even if the threshold value Y of the remote control signal is smaller than the threshold value X of the illuminance sensor, if the ambient illuminance is smaller than the threshold value Y of the remote control signal as long as it is within the output lower limit range of the illuminance sensor, Remote control signal determination does not work.

  Therefore, as shown in FIG. 12C, the remote control signal is configured so that its output c is smaller than the minimum output value a of the illuminance sensor, and the threshold value Y of the remote control signal at that time is the illuminance It is set outside the sensor signal output range.

(Embodiment 2)
The second embodiment will be described with reference to FIGS. Here, the operation when a signal from the lighting device 1a is input to the lighting device 1b will be described by taking as an example a case where an illuminance sensor signal is input as an analog input signal and a human body detection sensor signal is input as a digital input signal.

  In general, a lighting fixture equipped with both the illuminance sensor 15 and the human body detection sensor 17 should be turned off regardless of whether or not a person is detected if it is bright, and turned on if a person is detected when it is dark. This embodiment is also described on the premise of its operation.

  The operation of the illuminance sensor 15 is the same as that of the first embodiment. On the other hand, the human body detection sensor signal uses an infrared sensor, and is output as a human motion when there is a heat change in an arbitrary area, and here, a positive logic rectangular wave is output. .

  The pulse width of this rectangular wave is determined in proportion to the change in the amount of energy during human body detection. In general, the greater the heat change, the longer the output pulse width. Therefore, only when the pulse width is longer than an arbitrary pulse width, it is regarded as a thermal change due to movement of a person, and an output waveform with a short pulse width is regarded as a noisy thermal change, and the signal is ignored.

  In the control circuit unit 11, as in the first embodiment, if the input signal level does not exceed the threshold value Z of the human body detection sensor signal, the input signal is always used as the input of the illuminance sensor signal and the arbitrarily set threshold value X is set. Brightness / darkness discrimination of ambient illuminance is performed depending on whether it exceeds or does not exceed.

  On the other hand, whether or not the human body detection sensor signal is output for an arbitrary time or more is determined in the control circuit unit 11. First, in the control circuit unit 11, if the input signal exceeds the signal threshold value Z of the human body detection sensor 17, the input signal moves to time determination processing as a human body detection sensor signal. When the input for a certain time is confirmed, if the brightness is dark, the illumination load is turned on. When the input signal becomes equal to or less than the threshold value Z, it is determined that the time is equal to or less than a certain time, and the illumination load 3 is turned off.

  Again, when the human body detection sensor signal and the illuminance sensor signal are to be controlled separately, as shown in FIG. 14 (a), when the human body detection sensor signal is output, the illumination load 3 is turned on after a predetermined time. When the illuminance sensor 15 is affected by self-light, the output of the illuminance sensor 15 becomes a waveform that is raised while the illuminance sensor is lit. Mask processing is required. On the other hand, if the human body detection sensor signal is superimposed on the illuminance sensor 15 as in the present embodiment, it is regarded as a human body detection sensor signal at the time of lighting as shown in FIG. , The mask processing is not necessary.

  However, in the case where the human body detection sensor signal is a positive logic signal and the threshold Z of the human body detection sensor is smaller than the threshold X of the illuminance sensor, in the situation where the ambient illuminance exceeds the threshold Z of the human body detection sensor, The problem of “lights up without detection” occurs. Therefore, the threshold value Z of the human body detection sensor signal is always set to be larger than the threshold value X of the illuminance sensor.

  In addition, even if the threshold value Z of the human body detection sensor is larger than the threshold value X of the illuminance sensor, if the ambient illuminance exceeds the threshold value Z of the human body detection sensor as long as it is within the output upper limit range of the illuminance sensor 15 There is a problem that the signal is always regarded as a human body detection sensor signal and processing as an illuminance sensor signal cannot be performed. Therefore, as shown in FIG. 13, the human logic sensor signal of the positive logic signal has a circuit configured such that its output d is larger than the maximum output value b of the illuminance sensor, and the threshold value of the human sensor at that time Z is set outside the output range of the illuminance sensor signal.

  The same applies to the case where the human body detection sensor signal is a negative logic signal and is superimposed on the illuminance sensor signal. When the threshold value Z of the human body detection sensor is larger than the threshold value X of the illuminance sensor, the ambient illuminance is smaller than the threshold value Z of the human body detection sensor. In such a situation, the signal is always regarded as a human body detection sensor signal, which causes a problem that processing as an illuminance sensor signal becomes impossible. Therefore, the threshold value Z of the human body detection sensor of the negative logic signal is always set to be smaller than the threshold value X of the illuminance sensor.

  Even if the threshold value Z of the human body detection sensor is smaller than the threshold value X of the illuminance sensor, the ambient illuminance is smaller than the threshold value Z of the human body detection sensor as long as it is within the output lower limit range of the illuminance sensor 15. However, there is a problem that “lights up even if no person is detected”. Therefore, the human body detection sensor signal of a negative logic signal is configured so that the output d is smaller than the minimum output value a of the illuminance sensor, and the threshold value Z of the human body detection sensor at that time is the illuminance sensor signal threshold value Z. It is set outside the output range.

(Embodiment 3)
The third embodiment will be described with reference to FIGS. 15 and 16. Here, as an example of the operation when the signal from the lighting device 1a is input to the lighting device 1b, the illuminance sensor signal is input as an analog input signal, and the human body detection sensor signal and the remote control signal are input as digital input signals. explain.

  The operations of the illuminance sensor 15 and the remote control signal are the same as in the first embodiment, and the operation of the human body detection sensor signal is the same as in the second embodiment. However, one of the remote control signal and the human body detection sensor signal is configured to be a positive logic signal and the other is a negative logic signal so that the input is distinguished.

  In the control circuit unit 11, if the input signal level does not exceed the threshold value Z of the human body detection sensor signal and does not exceed the threshold value Y of the remote control signal, the light / dark discrimination is made with the threshold value X as the input as the illuminance sensor signal input. It is carried out.

  When either a human body detection sensor signal or a remote control signal is input and when either of the threshold values Z and Y is exceeded, the processing of the signal is started, and when the processing is completed, the threshold determination is performed again. If neither threshold is exceeded, the illuminance sensor signal is processed as input (FIG. 16).

  As in the first and second embodiments, the input levels of the remote control signal and the human body detection sensor signal are larger than the maximum output value b of the illuminance sensor signal in the case of a positive logic signal, and the negative logic signal In this case, the threshold value is set to be smaller than the minimum output value a of the illuminance sensor signal, and each threshold value is also set outside the output range of the illuminance sensor signal as in the first and second embodiments.
