1 and 2, the expandable multi-channel lighting control system includes a plurality of lighting groups 100, at least one switchboard 200 and a lighting control server 300, but is not limited thereto.

The lighting group 100 includes at least one lighting device 110 that is allocated to at least one channel and outputs light based on a predetermined illuminance value. At this time, the lighting device 110 may be an LED street light including a switching mode power supply (SMPS), and identification information is assigned to each lighting device 110 and each lighting group.

The switchboard 200 is connected to the lighting groups 100 one-to-one to provide power required for lighting, and transmits a lighting intensity control signal for determining an illumination value of the lighting devices 110 in each lighting group 100 to each lighting device 110. ) is provided.

The n number of branch breakers 220 are connected to each lighting device 110 to detect fault voltage and ground current to block the line, and are connected to loads (ie, lighting devices) to distribute electricity. do.

Since the LED street light is a lighting device exposed to the outside, it causes fatal damage when an overvoltage is introduced. Therefore, the main circuit breaker 210 and the branch circuit breaker 220 perform an overvoltage protection function to protect the SMPS and the lighting control module 230 in the event of lightning or other overvoltage inflow, so that the LED street light can be used smoothly.

The illuminance control module 230 generates a lighting illuminance control signal according to the lighting value transmitted from the lighting control server 300 and provides it to each lighting device 110 .

That is, the illumination intensity control signal includes the identification information of the lighting group, the identification information of the lighting device, and the illumination intensity value, so that the illumination intensity control according to the illumination intensity control signal is possible through the SMPS of the lighting device 110.

The communication module 240 performs communication between the lighting control server 300 and the illuminance control module 230, and although an M2M modem is used in the present invention, various communication modems capable of high-quality data communication can be applied. The M2M modem not only enables high-quality data communication, but also is used as a multi-purpose, high-performance LTE-only modem because there is almost no installation limitation due to its ultra-small and compact size.

In this case, the switchboard 200 includes a sensor (not shown) for sensing current, so that power consumption information for each lighting device or lighting group may be transmitted to the lighting control server 300 .

The failure detection module 520 collects driving state information for each lighting device 110 and the lighting group 100 through the illuminance control module 230, and the lighting device 110 and the lighting device 110 based on the collected driving state information. Using the identification information assigned to the lighting group 100, determine the location of the failure.

The illuminance setting module 530 sets and manages brightness for each lighting group according to a user-set illuminance value or an automatically set illuminance value.

In the scalable multi-channel lighting control system configured as described above, since the lighting control server 300 serves as a central control room, infinite expansion is possible for each lighting group of the LED street light, and control for each lighting group is possible.

On the other hand, the lighting control server 300 controls the power of the measurement capacity for each channel, and sets the lighting value to execute the lighting intensity control in a unit (%) of a preset illumination intensity change range according to the illumination intensity control signal. At this time, the lighting device 110 includes a sensor (not shown) for measuring the illuminance, and the lighting control server 300 can control the illuminance fluctuation range in % units using the automatically measured illuminance value, so that the user can Discomfort caused by changes in illumination can be minimized.

In addition, the lighting control server 300 may check the amount of power used per channel using an amount of power calculation algorithm. Therefore, the lighting control server 300 calculates real-time power usage, power savings compared to the standard amount of power, and the amount used according to the amount of power used and transmits the calculated amount to the manager terminal 400, so that the manager periodically uses the manager terminal 400 to determine the amount of power or the amount used.

In the switchboard 200, when 220V three-phase AC power is applied to the main circuit breaker 210, the main circuit breaker 210 regulates power supplied to the secondary side, and the secondary side is branched to distribute three and single phases, Three-phase and single-phase power is supplied to each lighting device 100 through a branch circuit breaker 220 . At this time, the illuminance control module 230 performs a phase control function for one phase of the three-phase AC power supply using a phase control function to apply the phase-controlled power to the branch circuit breaker to prevent phase collision.

In addition, due to the nature of the product, which is inevitable to be installed in a harsh environment when dissipating heat generated from the transistor for phase control due to a load during phase control with a heat sink and a cooling fan, damage to the product is inevitable if the cooling fan is destroyed. Accordingly, the present invention utilizes space and prevents product damage due to a heat dissipation structure in which the heat generated by the transistor is dissipated by a heat sink without installing a cooling fan.
