Further, RAM ₁ is a storage device such as RAM in which a program for determining the dependency relationship between the external light sensor 7 and the control unit is written and stored _in a changeable manner.
is a storage device for writing and storing _a program for _determining the dependency relationship between the pattern setting switches _{8 1 ,} 8 ₂ . A storage device such as RAM that writes and stores relationships in a configurable manner.
RAM ₄ is a RAM-like storage device that stores manual control information. 5a ₈ is the control panel 5 shown in Figure 2.
The output terminals ₁ ...i correspond to _the respective pattern setting switches ₈₁ , ₈₂ ....
Further, _5a6 is an input circuit for inputting information of the wall switches ₆₁ , ₆₂ , and output terminals 1...n correspond to the wall switches ₆₁ , 62, . _. ., respectively. Now, when an address of a control unit is first issued to the address line Z, the programs for the control unit of that address are output from the storage devices RAM1 to RAM4, respectively. In other words, when the user presses the pattern setting switches 8 ₁ , 8 ₂ . . . according to the purpose, the pattern control program data for the lighting fixture Bj specified by the address in the storage device RAM ₂ is stored in order to control the load according to the programmed pattern. P ₁ ~ Pi and input circuit 5a ₈
It is determined whether the lighting fixture (Bj) belongs to the pattern set by the pattern setting switch turned on by AND operation using the AND circuit _AND8i with data 1 to i from . Note that the subscript j of lighting fixture Bj indicates a unique number of lighting fixture B. Now, with pattern setting switch ₈₁ selected, P ₁ = “1”, P ₂ = “φ”, P ₃ =
If “1”, P ₄ = “φ”, P ₅ = “1”...Pi = “φ”, a signal of “1” can be obtained by the AND circuit AND ₈ corresponding to the pattern setting switch ₈₁ . As a result, since there is a dependent relationship between the control unit at that address and the pattern setting switch ₈₁ , and the pattern setting switch ₈₁ is turned on, it is determined that the control unit should be turned on. Similarly, by ORing the results of the calculations of the state of each pattern setting switch ₈₂ ... and the signal _P2 ... of the program contents using the OR circuit _OR1 , if the output of the OR circuit OR1 becomes " ₁ ". ”, at least one of the AND circuits up to AND ₈₁ …AND ₈₂
This means that the number has become "1". For example, in this embodiment circuit, it is possible to establish a dependent relationship between one control unit and a maximum of eight pattern setting switches ₈₈ , and if even one of them is established, the lighting signal is output from the OR circuit _OR1 . 1” signal is output. This operation will be explained in detail. First, if the relationship with the pattern settings (memory contents corresponding to each output P ₁ ... P ₈ of the storage device RAM ₂ ) is as shown in the table below, the control unit "1" is P ₁ , P ₃ , There is a dependent relationship between the outputs 1, 3, 5, _{and 7 of the input circuit 5a 8 that} inputs the information of the pattern switches 8 ₁ , 8 ₂ . . . corresponding to P ₅ , P 7 , and therefore Pattern switches 8 ₁ , 8 ₃ , 8 corresponding to the outputs of 5 and 7
When either ₅ , 8 or ₇ is turned on, the OR circuit is activated.
The output of OR ₁ is "1", and the meaning of "1" is that the optimal lighting condition can be selected depending on the purpose, time, external light conditions, etc., and it can be turned on during that pattern. It shows.

[Table] *Control unit No.
Next, the input circuit _5a6 is connected to the wall switch 6 as described above.
₁ , 6, ₂ ..., and similar to the pattern setting described above, arithmetic processing is performed in the storage device RAM ₃ , AND circuits AND ₆₁ , AND ₆₂ ..., and OR circuit OR ₂ . The calculation is to determine which wall switch 6 ₁ , 6 ₂ ... the lighting fixture Bj specified by the address is.
If _{the actual wall switches 6 1 ,} 6 _{2 .} . . _are turned on, the output of the OR circuit OR ₂ is set to be "1".
In this embodiment, one control unit can establish a dependent relationship with a maximum of eight wall switches 6 ₁ , 6 ₂ , and if one or more of them is established, the control unit at that address will be Gives an on signal. Next, the outputs of the OR circuits OR ₁ and OR ₂ are combined into one AND circuit AND 12, which combines the AND circuits AND ₁ and AND ₂ in Figure 12 _.
Enter. This AND circuit AND ₁₂ performs logic between the signals on the pattern side and the wall switch side, which means that the wall switch used to make the final decision to turn on the lighting equipment is on, and the output on the pattern side is "1". For example, as shown in Fig. 15, when P ₁ is "1" and P ₂ and P ₃ are "0" during the output of patterns A ₁ , A ₂ , A ₃ , the illumination Whether the wall switch 6 corresponding to fixture B is on or off, lighting fixture B is turned off and outputs P ₁ , P ₂ , P ₃
is "1" and the wall switch 6 is on, the lighting fixture B is lit. In this case pattern A ₁ A
It does not matter which output P ₁ , P ₂ , P ₃ of ~A ₃ causes lighting fixture B to turn on, but whether it turns on or turns off as a result. Considering this point, the AND circuit The logical processing of AND ₈₁ ..., AND ₆₁ ... and the OR circuits OR ₁ and OR ₂ have meaning.
The output of the NAND circuit NAND ₄ is also input to this AND circuit, and depending on the address setting, the memory device
Data “1” related to the external light sensor program is output from RAM ₁ , and the information of external light sensor 7 is “1”.
If so, the output of the NAND circuit NAND ₄ becomes "φ", and the lighting fixture Bj specified by the address is turned off (however, this changes depending on the state of the individual operation). Also,
The output of the AND circuit AND ₁₂ becomes "φ", and the pattern setting switches 8 ₁ , 8 ₂ . . . , wall switches 6 ₁ ,
6 ₂ The off signal is set regardless of the state of . When the information of the external light sensor 7 is off or the output of the storage device RAM ₁ is “φ” (no dependent relationship), the NAND circuit is activated.
The output of NAND ₄ becomes “1” and the OR circuit OR ₁ ,
The result of OR ₂ will be followed. At this time, the program signals of the pattern setting switches 8 _{1 ,} 8 _{2 .} . . match even one set of the signals of the pattern setting switches 8 ₁ , 8 ₂ .
When the program signal of the wall switch 6 ₁ , 6 _{2 .} . . matches even one set of signals, the AND circuit AND ₁₂
outputs a “1” signal. In this state, the control panel 5
Outputs a signal of "1" when the lighting pattern given by the pattern setting switches 8 ₁ , 8 ₂ . . . on the wall overlaps with the control area of the wall switches 6 ₁ , 6 ₂ . . Then the OR circuit
OR ₃ has the output of the AND circuit AND ₃ , and the AND circuit
Since it contains the output of AND ₁₂ , it is a storage device for storing data for individual operation (temporarily forcibly turning on and off lighting fixture Bj from control panel 5).
If the manual control information contained in RAM ₄ is output Q ₁
If ="1" and output Q ₂ = "1", it is an AND circuit.
The gate signal of _AND5 becomes "1", and this "1" signal provides a "1" signal to _{the AND circuit AND3 as} the above-mentioned ON signal Y1.
Therefore, if the wall switch that is dependent on the lighting fixture Bj specified by the address is turned on, it can be turned on even if the output of the AND circuit AND ₁₂ is "φ", and further manual control is possible. Even if the information is on (Q ₁ = 1, Q ₂ = 1), if the wall switch that controls the control area is off, it will be off, and even if the lighting fixture 3 is turned on by manual control, the control area will be turned off. The wall switch that controls 6 ₁ ,
6 ₂ ... can be controlled. In addition, this function works even if the outside light sensor 7 operates and the output of the NAND circuit NAND ₄ becomes "φ" and the lighting fixture in the control area is forcibly turned off, the wall switch 6 ₁ that controls the control area When 6 _{2 .} . . is turned on, it can be turned on temporarily by manual control. On the other hand, the output of storage device RAM ₄ is Q ₁ =
1. Even if the output of the AND circuit AND ₁₂ where Q ₂ = φ becomes “1” and outputs the on signal Y ₁ , the AND circuit _{AND 3 is closed by the off signal Y 2 which} is the output of the NAND circuit NAND 2. , wall switch 6 ₁ ,
6 ₂ ... can be turned on and when there is an unnecessary lighting fixture 3 in use, it can be forcibly turned off. The above operation completes the production of a control signal for one control unit, and then the address sent to the address line Z is changed and control signals are sequentially produced in the same manner. In this way, in the above-described embodiment, the lighting (lighting) pattern can be specified from the control panel 5 using the pattern setting switches 8 ₁ , 8 _{2 .} . . , making it possible to increase the power saving effect. Since overlapping lighting patterns of the pattern setting switch can be obtained, extremely fine control is possible. In addition, since the control area by the wall switches 6 ₁ , 6 _{2 .} . . is determined by the program, the user can control the control area convenient for the user, and whenever an inconvenience occurs, a better control area can be set by changing the program. You can also set the wall switch 6
₁ , 6, ₂ ... is possible, so it is possible to prevent unnecessary lighting equipment 3 from being turned on at the border of the control area, which is inconvenient in the conventional method. With the light-off program 7, the area where the light is turned off by the outside light sensor 7 can be arbitrarily changed, depending on the season and the surrounding environment, and even if the light is forcibly turned off by the operation of the outside light sensor 7, the area where the light is turned off can be changed temporarily. If you want to turn on the lighting fixtures 3 in the unlit area, you can turn them on by operating the manual control input keyboard 9, and the lighting fixtures 3 in the control area of the wall switches ₆₁ , ₆₂ ... can be turned on by the pattern setting switch 8. ₁ , 8, _2, etc., it can be turned on temporarily by operating the manual control input keyboard 9, and furthermore, the lighting equipment 3 can be turned off by turning off the wall switches ₆₁ , ₆₂ , etc. The lights can be turned off by turning on the wall switches 6 ₁ , 6 ₂ , etc.
It has the rationality of prioritizing the operation of Furthermore, if the pattern setting switches _{8 1} , _{8 2 .} . . It is safe to form and there is no wear and tear on the switch contacts due to arcing. Data writing into the storage devices RAM ₁ to _{RAM 4} is performed by a well-known microcomputer system, and the input method is performed by well-known software processing. In other words, if you first input data to the memory device RAM ₄ by individual operations from the keyboard, such as lighting fixture B ₁ on, B ₂ on, B ₃ on..., Bj on, for each address, the 13th
A microcomputer controls the lighting equipment according to a program according to the logic expressed by the circuit representation in the figure, and after confirming the control, moves the data contents to the corresponding item. For example, if the program is for _P1 , the program is completed by sequentially moving the stored contents of the storage device RAM ₄ to the _P1 position of each corresponding address from lighting fixture _B1 to the first lighting fixture _B2 . In this way, the setting of each data of P ₁ to Pi, W ₁ to W _o , and X is completed. The present invention provides a control panel with a plurality of pattern setting switches for setting lighting patterns, writes the dependent relationship with each control unit of the terminal device in a storage device whose contents can be changed, and responds to turning on of the pattern setting switch. Since the control signal to the control unit in a dependent relationship with the pattern setting switch is used as a signal to activate the lighting equipment, and the control signal to the control unit in a non-dependent relationship is used as a signal to deactivate the lighting equipment, the user Lighting equipment can be controlled in various lighting patterns using a pattern setting switch from the central control panel, unnecessary lights can be turned off automatically, increasing power saving effects, and the contents of the storage device can be changed. The lighting pattern can be easily changed to the desired lighting pattern as needed by simply changing the lighting pattern, and there is no need for modification work to change the lighting pattern, which has the excellent effect of being highly flexible. .
