DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting system, and more particularly, to a lighting system for linking a plurality of lighting devices using infrared rays.

[0002]

2. Description of the Related Art There have conventionally been various techniques as a lighting system for linking a plurality of lighting fixtures. For example, FIG.
There is a conventional lighting system shown in FIG. In FIG. 10, 9
Are infrared remote controllers (hereinafter simply referred to as remote controllers), 10
Denotes an infrared ray transmitted from the remote controller 9, and 11 denotes a floor surface. Reference numerals 40 to 42 denote fluorescent lamps, which are one of the lighting fixtures. Although three fluorescent lamps are shown in the figure, an actual lighting system is configured with more lighting fixtures. A control device 43 receives the infrared rays 10 from the remote controller 9. Control device 33
The signal line 34 is connected to the fluorescent lamp appliances 40 to 42 from
The controller 43 operates to convert the infrared rays 10 received by the controller 43 into electric signals and to transmit the electric signals to the fluorescent lamp appliances via the signal lines 44.

[0003] In the lighting system shown in FIG. 10, a dimming degree indicating the brightness of a fluorescent lamp is transmitted from a remote controller 9 using an infrared ray 10 as a medium to a control device 43. The control device 43 that has received the infrared light 10 generates an electric signal so as to have a dimming degree indicated by the infrared light 10 and uses the signal line 44 to connect the fluorescent lamp appliances 40 to 40.
42. The fluorescent lamp devices 40 to 42 are controlled by a control device 43.
Turn on the fluorescent lamp with the dimming degree sent from. Therefore,
The brightness of the lighting fixture can be controlled from the remote controller 9.

[0004]

However, FIG.
In the conventional lighting system shown in (1), since the control device 43 controls the plurality of fluorescent lamp appliances 40 to 42, it is necessary to connect the control device 43 and the fluorescent lamp appliances 40 to 42 with the signal line 44. However, there is a problem that the construction is costly. In addition, there is a problem that it takes time to change the existing fluorescent light fixture. Therefore, an illumination system shown in FIG. 11 has been proposed to solve this problem. In FIG. 11, reference numerals 22, 27, and 32 denote fluorescent lamp appliances each including a fluorescent lamp 2, an infrared receiving unit 5, and an infrared transmitting unit 6, and 9 denotes a remote controller. In this configuration, a control signal including a dimming signal indicating the brightness of the fluorescent lamp 2 is transmitted by infrared rays 10a. Reference numeral 11 denotes a floor surface. The dimming signal from the remote controller 9 is received by the infrared receiving section 5 provided in the fluorescent lamp fixture 26. The lighting device 4 of the fluorescent lamp apparatus 26 sets its own fluorescent lamp to the reception dimming degree, and transmits the infrared signal received earlier, that is, the same signal as the infrared signal transmitted from the remote controller, from the infrared transmitter 6. .

The infrared ray 10 transmitted from the fluorescent lamp fixture 26
b is reflected by the floor surface 11 and sent to the adjacent fluorescent lamp fixture 27. Similarly, the fluorescent lamp fixture 27 and the fluorescent lamp fixture 32 also perform dimming of their own fluorescent lamps 2 and transmit the infrared rays 10c and 10e. As described above, the control signal emitted from the remote controller 9 is sequentially transmitted to the adjacent fluorescent lamp appliances by infrared rays, and all the fluorescent lamp appliances are dimmed, so that the wiring of the signal line becomes unnecessary.

However, in the above configuration, when the fluorescent lamp appliances 22, 27, and 32 receive infrared rays from the remote controller 9 or another fluorescent lamp appliance, they play a role of relaying a signal to an adjacent fluorescent lamp appliance. It is necessary to transmit the same infrared ray as the received infrared ray. At this time, when a plurality of fluorescent lamps simultaneously receive infrared rays, the infrared rays are transmitted from all of the received fluorescent lamps, and the collision of infrared rays occurs. Infrared light has a problem that control signals such as dimming signals are pulse-modulated and superimposed, so that the control signals disappear, making it impossible to transmit the control signals.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a lighting system which eliminates the need for wiring a signal line to each lighting fixture and can prevent collision of infrared rays. Is to do.

[0008]

In a lighting system that performs transmission and reception, the lighting equipment has storage means for storing a transmission number and a group number that are respectively assigned to the lighting equipment and that define the transmission order of the infrared light, the infrared remote control, or
When a control signal in which dimming degree information, group number information, and transmission number information are added to the control signal from the other lighting apparatus is received for the first time, the group number information of the control signal is stored in the storage unit. If the group number matches the group number, the dimming process is performed based on the dimming degree information of the control signal. If the group number information does not match the group number, the dimming process is not performed. In both the case where the transmission number matches and the case where the transmission number does not match, the transmission number information of the control signal is changed to its own transmission number stored in the storage means to generate a control signal, and the transmission time zone is calculated from the own transmission number. And outputting the generated control signal to the transmitting means during the transmission time period, and when receiving the control signal for the second time, outputs the dimming process and the output of the control signal. A control means does not perform as well.

Further, the transmission number stored in the storage means is
The lighting devices arranged adjacent to each other are connected in order, and the lighting devices having the first and last transmission numbers are arranged so as to be adjacent to each other.

Next, the internal configuration of the fluorescent lamp device 1 will be described with reference to the block diagram shown in FIG. In a lighting device 4 connected to the fluorescent lamp 2 for lighting the fluorescent lamp 2, an infrared receiver 5 receives infrared light, demodulates the infrared light pulse-modulated by the data code of the control signal, and converts it into an electric signal. Is an infrared transmitter that pulse-modulates infrared light that has been amplitude-modulated by a carrier wave (38 KHz) with a data code and transmits a control signal.

12 is an infrared receiver 5 and an infrared transmitter 6
, And decodes the control signal received by the infrared receiver 5, sends it to the inverter 9 as a dimming signal, and dims the fluorescent lamp 2 by the inverter 9. Further, the control signal received by the infrared receiver 5 is assembled and sent to the infrared transmitter 6.

As shown in FIG. 4B, one frame of the infrared signal which is a control signal basically includes a reader section, a data section and a trailer section. Further, FIG.

It is subdivided into parity codes. And the dimming degree, group and transmission number are
Each of them becomes dimming degree information, group number information, and transmission number information.

As described above, since the infrared signal is pulse-modulated, it becomes a pulse train as shown in FIG. 4 (4). For example, the reader unit outputs "1" for 8T time and "0" for 4T time. It consists of. Here, T indicates a basic pulse width, which is set to, for example, 0.4 ms. Similarly, for signal 0, T
The signal 1 is composed of "1" for the time T and "0" for the T time, and the signal 1 is composed of "1" for the T time and "0" for the 3T time. FIG. 4 (5)

FIG. 5 shows the arrangement of the fluorescent lamp fixture of the lighting system of the present invention. In the figure, reference numeral 20 denotes a room in which the lighting system of the present invention is installed. 21 to 32 are each shown in FIG.
2 shows a fluorescent lamp apparatus similar to that shown in FIG. The two numbers inside [] indicate the appliance number and the parentheses indicate the transmission number. For example, the fixture number of the fluorescent lamp fixture [1] 21 is 1,
The transmission number is 3. The fluorescent lamp devices 21 to 32 are arranged side by side in four rows and three columns in the drawing. The device numbers are assigned from left to right and from top to bottom. On the other hand, the transmission numbers are arranged so that the transmission numbers start from the center, connect the transmission numbers to adjacent devices in order, and further, the transmission numbers start and end adjacently. That is, the fixture number 6 is set to the transmission number 1 and assigned to each fluorescent lamp fixture in the order of arrow (1), arrow (2), arrow (3),..., Arrow (11). Therefore, the fluorescent lamp appliance of the transmission number 1 and the fluorescent lamp appliance of the last transmission number 12 are adjacent to each other.

The fluorescent lamps 21, 22, 25 and 26 are set to group 1, and the fluorescent lamps 23, 24,
27 and 28 are group 2, fluorescent lighting fixtures 29, 30, 3
1, 32 are set to belong to group 3. This group number information is set in the control unit 12 in the lighting circuit 4 in advance. This group represents a dimming setting group from the remote controller 9 and is used, for example, for the purpose of setting only the group 1 from the remote controller 9 to a predetermined dimming degree. This information is set in the group section of the infrared signal configuration shown in FIG. Further, the transmission of the remote controller 9 is set to 0, which is a reference of the transmission order. Therefore, "0" is inserted in the transmission number part of the infrared signal transmitted from the remote controller.

In the room 20 in which the fluorescent lamp appliances 21 to 32 are arranged as described above, the remote controller 9 controls the fluorescent lamp appliance [6].
It is assumed that an infrared signal with dimming degree information, group number information, and transmission number information is transmitted toward. In addition, the content of the infrared signal is to set the group 1 to a predetermined dimming degree. Therefore, the group number information of the internal signal of the infrared signal shown in FIG.
Further, the set dimming degree is input to the dimming degree section. The infrared signal from the remote controller 9 is received by the fluorescent lamp device [6] 26, and further transmits an infrared signal similar to the infrared signal received from the fluorescent lamp device [6] 26. Since the infrared signal is transmitted to an adjacent fluorescent lighting device using reflection from a floor or the like, a reception range is formed in a circle around the fluorescent lighting device [6] 26.
The area of the circle shown in FIG.

In the receiving range 33, a fluorescent lamp device [6] 26
There are a fluorescent lamp [2] 22, a fluorescent lamp [7] 27, a fluorescent lamp [5] 25, and a fluorescent lamp [10] 30 adjacent to each other. These four fluorescent lamp appliances receive the infrared signal transmitted from the fluorescent lamp appliance [6] 26. Similarly, the infrared signal transmitted by the fluorescent lamp device 21 is a fluorescent lamp device [2] 22 and a fluorescent lamp device [5] 25,
The infrared signal transmitted by the fluorescent lamp device [2] 22 is a fluorescent lamp device 21, a fluorescent lamp device [3] 23, and a fluorescent lamp device [6].
26.

Next, how to transmit an infrared signal will be described with reference to a timing chart shown in FIG. The vertical axis in FIG. 6 represents the transmission time allocated to the transmission number of the remote controller and each fluorescent lamp appliance, and the horizontal axis represents the transmission time allocated to the transmission number of the remote controller and each fluorescent lamp appliance 21 to 32. The transmission order is specified in order from 0 at an interval of a predetermined time unit in numerical order. That is, the transmission numbers are assigned in a time-division manner for each time zone. A block shown by a rectangle in FIG. 6 represents one frame of the infrared signal described with reference to FIG. 4. In the same fluorescent lamp device, a black rectangle is a transmission frame, and a gray rectangle is a reception frame. When the group number information of the received fluorescent lamp fixture and the received signal in the received frame matches, a black circle is displayed inside the rectangle, and when they do not match, a circle is displayed. Those without the symbols ● and ○ indicate the same infrared signal received twice or more.

The transmission time = 0 when the remote controller 9 transmits the signal toward the fluorescent lamp device [6] 26. Transmission time = 0
In the time zone, the infrared signal from the remote controller 9 is received by the fluorescent lamp device [6] 26. A thick arrow drawn from a black rectangle to a gray rectangle of the remote controller 9 shown in FIG. 6 represents an infrared signal. In addition, in the same fluorescent lamp device, the timing from reception to transmission is indicated by a thin arrow. Transmitting fluorescent light fixture [6]
26 belongs to group 1 and thus matches the group number information in the infrared signal received by the infrared receiver 5 shown in FIG. When the group number information matches, the control unit 12 shown in FIG. 3 decodes the dimming degree information in the received infrared signal and sends it to the inverter unit 13, which dims the fluorescent lamp 2 (hereinafter, dimming). Light processing). In addition, the control unit 12 calculates a time zone in which the control unit 12 can transmit itself from the transmission number information of the received infrared signal. That is,
Since the transmission number of the reception is 1 and the transmission number of the fluorescent lamp device [6] is 1, it is known that the transmission is possible in the next time zone after the reception. Then, when the transmission number = 1 is reached,
The control unit 12 transmits the same content as the infrared signal received from the infrared receiving unit 6 (hereinafter, referred to as transmission processing). However,
As the transmission number, 1 assigned to the fluorescent lamp device [6] 26 is inserted.

In the time zone of the transmission number = 1, the fluorescent lamp [2] 22, the fluorescent lamp [5] 25, the fluorescent lamp [7] 27 and the fluorescent lamp [10] within the reception range 33 shown in FIG. ] 30 receives an infrared signal from the fluorescent lamp device [6] 26. In FIG. 6, the tip of the arrow at the signal number = 1 is the received fluorescent light fixture. At this time, the fluorescent light fixture [2] 22
Then, the fluorescent lamp device [5] 25 has the same group number information as the reception of the fluorescent lamp device [6] 26, and performs dimming of its own fluorescent lamp 2. Since the fluorescent lamp fixture [7] 27 and the fluorescent lamp fixture [10] 30 are group 2 and group 3, respectively, the group number information in the received infrared signal does not match, and the light of the fluorescent lamp 2 is not adjusted. Each of the four fluorescent lamp appliances receiving the transmission number = 1 transmits the infrared signal with the transmission number assigned to itself. The fluorescent lamp fixture [2] 22 performs transmission processing with the transmission number = 2, and the fluorescent lamp fixture [5] 25 performs transmission processing with the transmission number = 4, and does not perform the light control processing because the group number information does not match [7]. 27 performs the transmission process of the infrared signal similarly for the transmission number = 12 and the fluorescent lamp apparatus [10] 30 for the transmission number = 6.

When the transmission number is 2, the fluorescent lamp [2] 22 similarly transmits an infrared signal, and the fluorescent lamp [1] 2
1. Fluorescent lighting equipment [3] 23 and fluorescent lighting equipment [6] 26
Receive. The fluorescent lamp device [1] 21 performs a dimming process and a transmission process when the group number information matches, and the fluorescent lamp device [3].
23 performs only the transmission process without performing the dimming process due to the group number information mismatch, and the fluorescent lamp fixture [6] 26 performs the same signal 2
This is the second reception, and neither the light control processing nor the transmission processing is performed. Transmission and reception of infrared signals are similarly performed for transmission numbers 3 to 12. As is clear from FIG. 6, the transmission frames indicated by black blocks transmitted from the respective fluorescent lamps are transmitted in a time-division manner without overlapping, and the infrared signals are sequentially received by the fluorescent lamp. In addition, at least two fluorescent lamps can be used.
Times, the same infrared signal is received. This can result, for example, in a loss of signal to travel first,
Even if an error occurs, if normal reception is possible with the next reception signal, the dimming process and the transmission process of each fluorescent lamp device are performed without any problem.

Next, a description will be given of another fluorescent lighting device from the remote controller 9, here, a fluorescent lighting device [7] 27 assigned at the end of the transmission order with reference to FIGS. 7 and 8. The setting from the remote controller 9 controls the light of the group 1 in the same manner as described above. In FIG. 7, reference numeral 34 denotes a reception range of an infrared signal emitted from the fluorescent lamp device [7] 27 which first receives an infrared signal from the remote controller 9. The transmission time = 0 when the remote controller 9 transmits the signal toward the fluorescent lamp device [7] 27. In the time zone where the transmission time = 0, the infrared signal from the remote controller 9 is received by the fluorescent lamp [7] 27, and the fluorescent lamp [7] 27 performs only the transmission process because the group number information does not match. Since the transmission number assigned to the fluorescent lamp device [7] 27 is 12, after a lapse of a time obtained by multiplying the predetermined time by the number 11 based on the received infrared signal, that is, at the timing of transmission number = 12 Perform transmission processing.

At the transmission number = 12, the infrared signal from the fluorescent lamp fixture [7] 27 is transmitted to the fluorescent lamp fixture [3] 2
3, received by the fluorescent lighting device [6] 26, the fluorescent lighting device [8] 28, and the fluorescent lighting device [11] 31. Then, when the infrared signal is transmitted from the fluorescent lamp device [6] 26 with the transmission number = 1, the infrared signal is sequentially transmitted to each of the fluorescent lamp devices [1] 21 to [12] 32 as in FIG. . Therefore, the transmission order is repeated from 0 after 12. FIG.
As is clear from FIG. 6, similarly to FIG. 6, the transmission frames indicated by black blocks transmitted from the respective fluorescent lamp appliances are transmitted in a time-division manner without overlapping, and the infrared signal is sequentially received by the fluorescent lamp appliance. Also, at least two times with one fluorescent light fixture,
The same infrared signal will be received.

As described above, in the case where the fluorescent lamp appliance received first from the remote controller 9 has the earlier transmission order, the transmission and reception of the infrared signal is completed within one round of the transmission order. Also, when the fluorescent lamp fixture set at the end of the transmission order receives the infrared signal from the remote controller 9 first, the infrared transmission / reception has been completed before the transmission order goes twice. Thus, it can be seen that the infrared signal is smoothly transmitted in the two cases. This is because the transmission numbers are allocated so that the transmission numbers are connected to adjacent devices in order, and further, the transmission order is arranged so that the beginning and the end of the transmission order are adjacent. The purpose of this is to secure a path through which an infrared signal is transmitted, regardless of which fluorescent light fixture first receives.

For example, in an illumination system in which the number of fluorescent lamps installed is slightly larger, the setting is performed in the order of arrows as shown in FIG. In FIG. 9, rectangles indicate fluorescent lamp appliances, which are arranged at equal intervals of six vertically and six horizontally. The number inside the rectangle indicating the fluorescent light fixture represents the transmission number. As is clear from the figure, the transmission order is set in a one-stroke form.
