FIG. 5 is a block diagram according to an embodiment of each of the first to Mth controllers 120A-1 to 120A-M 120A-m illustrated in FIG. 1.

The m th controller 120A-m illustrated in FIG. 5 includes a power supply 122, a storage 124, a micro-computer 126A, and an illumination driver 128. Here, the microcomputer 126A is a kind of computer and may include a memory (not shown), a processor (not shown), and an input / output port (not shown).

The storage unit 124 stores the ID of the PC located in the lighting area of the m-th lighting unit 110-m among the first to K-th PCs 130-1 to 130 -K.

The microcomputer 126A receives all of the first to K-th user status signals generated by each of the first to K-th PCs 130-1 to 130 -K through the lighting side communication unit 160, and sends them to the storage unit 124. A corresponding user state signal of the first to K-th user state signals is selected using the stored ID, and a driving control signal is generated according to the selected user state signal.

The lighting driver 128 outputs a lighting control signal for controlling lighting of the m-th lighting unit 120A-m through the output terminal OUT1 according to the driving control signal received from the microcomputer 126A.

For example, when m = 2, referring to FIG. 3, the storage unit 124 of the second control unit 120A-2 includes a second lighting unit among the first to tenth PCs 130-1 to 130-10. IDs of the second and seventh PCs 130-2 and 130-7 located in the lighting regions 150-2 and 150-7 of 110-2 are stored.

In this case, since the ID of the PC stored in the storage unit 124 indicates the second PC 130-2 and the seventh PC 130-7, the microcomputer 126A is the first of the first to K-th user status signals. Only the second and seventh user status signals are selected as corresponding user status signals. At this time, the microcomputer 126A determines the presence or absence of the second and seventh users who use the second and seventh PCs 130-2 and 130-7 through the second and seventh user status signals, respectively. The determined result is output to the lighting driver 128 as a driving control signal.

When one of the second and seventh users is recognized as being occupied by the driving control signal, the lighting driver 128 outputs a lighting control signal for lighting the second lighting unit 110-2 through the output terminal OUT1. However, when it is recognized that both the second and seventh users are absent through the driving control signal, the lighting driver 128 outputs a lighting control signal for turning off the second lighting unit 110-2 through the output terminal OUT1.

Meanwhile, as illustrated in FIGS. 2A to 2F, when each of the first to Mth lighting units 110-1 to 110 -M includes a plurality of lighting cells, the first to Mth control units 120A-1 to 120A. Each of the -M) controls the lighting of the plurality of lighting cells in the first to Mth lighting units 110-1 to 110 -M as follows.

The storage unit 124 not only stores the ID of the PC but also stores a mapping table in which the ID and the plurality of illumination cells are mapped. The microcomputer 126A generates a local dimming signal according to the mapping table stored in the storage unit 124 and the user state signal selected as described above. The lighting driver 128 outputs a lighting control signal for controlling selective lighting of a corresponding cell among the plurality of lighting cells according to the local dimming signal through the output terminal OUT1.

For example, when the second lighting unit 110-2 illustrated in FIG. 3 includes divided lighting cells 112B ˜ 118B as illustrated in FIG. 2B, the second lighting unit 110-2 controls the second lighting unit 110-2. The storage unit 124 included in the second control unit 120A-2 may store a mapping table as shown in Table 1 below.

Lighting cell numbers ID of PC 116B k = 2 118B 112B k = 7 114B

In the mapping table of Table 1, the illumination cells 112B and 114B of the illumination cells 112B to 118B of FIG. 2B are mapped with the seventh PC 130-7 (k = 7), and the illumination cells 116B and 118B are provided. ) Is mapped to the second PC 130-2 (k = 2).

The microcomputer 126A analyzes the second and seventh user state signals selected from the first to K th user state signals to recognize the absent user and the user in the occupancy state among the second and seventh users. If the second user is in the occupancy state and the seventh user is absent, the local dimming signal is generated with reference to the table shown in Table 1 stored in the storage unit 124. Here, the local dimming signal turns on the illumination cells 116B and 118B mapped to the second user (k = 2) side in the occupancy state, and the illumination cells 112B mapped to the absent seventh user (k = 7) side. , 114B). To contain this information, the local dimming signal may be a signal in the form of pulse width modulation (PWM). Thereafter, the lighting driver 128 selectively turns on or turns off the corresponding illumination cell according to the pulse width of the local dimming signal.

The brightness of each of the first to Mth lighting units 110-1 to 110 -M may have a default value, but may be set by a user as described above. In addition, although the brightness information for each divided lighting cell included in each of the first to Mth lighting units 110-1 to 110 -M may also have a default value, it may be set by a user.

If the brightness of each of the m-th illumination unit 110-m and / or each of the illumination cells is set by the user, it is transmitted to the m-th control unit 120A-m through a user status signal. The microcomputer 126A of the m-th control unit 120A-m checks the brightness degree set by the user through the user state signal selected from the first to Mth user state signals, and generates a brightness control signal according to the checked result. To the lighting driver 128. The lighting driver 128 controls the brightness degree of the m-th lighting unit 110-m through the output terminal OUT1 according to the brightness control signal received from the microcomputer 126A.

At this time, the microcomputer 126A of the m-th control unit 120A-m generates a brightness control signal according to a result of checking the number of users in the occupancy state through the selected user state signal, and the lighting driver 128 The maximum brightness of the m-th lighting unit 110-m may be limited according to the brightness control signal. For example, if the number of users in the occupancy is large, increase the brightness of the m-th lighting unit 110-m. If the number of users in the occupancy is small, the brightness of the m-th lighting unit 110-m may be reduced. Can be.

In addition, the m-th control unit 120A-m may request transmission of the user status signal to the PC which has generated the selected user status signal among the first to K-th PCs 130-1 to 130 -K. In this case, the PC receiving the request transmits the user status signal generated by itself wirelessly. This is to control the lighting of the lighting unit at the optimum brightness level according to the number of users. That is, when the k-th user status signal is given, before or while the m-th lighting unit is turned on, based on the k-th user status signal, other first to k-th user status signals other than the k-th user status signal And a user state signal to adjust the brightness level of the m th illumination unit with reference to at least one other user state signal among k + 1 to Kth user state signals.
