Smart Lighting Control Systems

Smart Lighting Control System for Industrial Sites

A smart lighting control system for industrial applications is a switching, regulation and scheduling layer installed between the distribution board and the lighting circuits. LOGGON TECH supplies two such devices: the LOGGON-2C smart energy-saving lighting controller and the LOGGON-2D smart energy-saving lighting control cabinet. Both are intended for three-phase four-wire 380VAC networks and are used in industrial parks, plant roads, yards and similar outdoor or mixed-use facilities. The operating principle is voltage stabilisation and reduction: the controller regulates the output voltage by solid-state relay chopper regulation or by transformer regulation, so lamps operate at a reduced, stabilised voltage instead of the full line voltage. The manufacturer states this method saves energy, extends lamp life and reduces maintenance. Control is selectable per installation: time control, light control, mixed time and light, manual, host-computer remote control, latitude/longitude (astronomical) control and wireless control.

What it does

The unit performs three functions in one enclosure: switching lighting groups on and off, regulating output voltage, and executing a control schedule. Input is three-phase four-wire, 380VAC ±20%. Output voltage is held in a reduced band — 190–220VAC on the LOGGON-2C and 190–230VAC on the LOGGON-2D — rather than following the incoming line. Rated current per phase on the LOGGON-2C spans 30A to 350A; the LOGGON-2D is rated 30–60KVA total capacity.

Control modes are selected according to site conditions. Time control follows a fixed switching schedule; light control uses a photocell threshold; mixed time and light combines both so switching occurs only inside the permitted window; manual control allows direct operation during commissioning or maintenance. Latitude/longitude control calculates sunrise and sunset from the site's geographic position, so switching times track the seasonal day-length change without manual adjustment. Host-computer remote control connects the unit to a supervisory system; wireless control is also listed (optional on the LOGGON-2D).

Voltage reduction must be evaluated against the lamp type and ballast installed. Discharge lamps with magnetic ballasts and LED drivers with wide input tolerance behave differently at reduced input voltage; engineers should confirm the permitted input range of the luminaires before setting the output band. The control and communication interface on both models is RS-485 with Modbus-RTU, which allows integration into a plant SCADA or energy management system.

Models and key data

Two models are available; both share the same control-mode set. Differences are enclosure type, output band, capacity and the number of communication ports.

Architecture and integration

The controller sits downstream of the lighting distribution board and upstream of the lamp groups. Each outgoing circuit is switched and regulated by the unit. The control modes are executed by the unit itself, including the listed time, light and astronomical modes. The LOGGON-2D provides two RS-485 ports with Modbus-RTU, which connect the cabinet to a host computer or supervisory system, so a plant engineer can include lighting in the same monitoring environment used for other utilities. Latitude/longitude and mixed time+light modes are also among the listed control modes, and wireless control is available where a cable route is impractical.

Sizing starts from the connected load per phase and the number of controlled groups. Select the model against the documented rating basis for the installation: the LOGGON-2C is rated by current per phase (30A to 350A); the LOGGON-2D cabinet model is rated 30–60 KVA. Confirm which rating basis applies to your circuits with the export department. Confirm the luminaire input tolerance, the required switching sequence and whether a photocell input is needed before specifying the mode set.

Applications

• Industrial park internal roads and perimeter roads
• Plant yards, loading areas and storage compounds
• Car parks and access roads serving factory buildings
• Outdoor area lighting on sites where lamp maintenance access is difficult and lamp life affects maintenance cost

These are industrial and infrastructure lighting loads, not residential smart-home fittings. The value in this segment is predictable switching, a stable reduced output voltage and a communication interface that a plant electrical team can integrate.

FAQ

Does the smart lighting control system work on a 380VAC supply with wide voltage fluctuation?

Yes. Both models accept three-phase four-wire input at 380VAC ±20%, and the output is regulated to the stated band (190–220VAC for the LOGGON-2C, 190–230VAC for the LOGGON-2D) rather than following the incoming line.

Which control mode should be specified?

For roads and yards with a stable daily pattern, latitude/longitude control usually removes manual seasonal adjustment. Where a photocell is already installed, mixed time + light keeps switching inside a permitted window. Manual and host-computer remote control are typically added for commissioning and central supervision.

Can it be connected to a plant monitoring system?

Both models provide RS-485 with Modbus-RTU. The LOGGON-2C has one port; the LOGGON-2D has two RS-485 ports; how the ports are assigned in a given installation follows the project documentation.

Is reduced output voltage suitable for all luminaires?

Not automatically. Check the input voltage range of the ballast or LED driver and the manufacturer's guidance for the installed lamp type before fixing the output band. The regulation method is voltage stabilisation and reduction; suitability depends on the luminaire.
