Wireless Lighting Control System

The Thorlux Smart System exploits the latest ‘Digital Technology’ to provide a simple, effective method of lighting control which minimises energy consumption whilst retaining high levels of user comfort.

Projects utilising the Thorlux Smart System can frequently benefit from savings in excess of 70% energy when compared with conventional technology.

A discrete sensor integral to the luminaire monitors ambient light and presence controlling output to the correct level, and ensuring that the area is only illuminated when occupied.

Individual Thorlux Smart luminaires may be linked using a ‘Motionline’ two wire low voltage bus allowing luminaires to communicate within a group. If any one luminaire detects movement all connected luminaires within the group will illuminate.

This valuable feature is designed to eliminate the possibility of a user being isolated in a small pool of light, surrounded by intimidating darkness. Motionline ensures that there will always be a well lit comfortable environment.

Motionline wiring also allows other digital signals, for example from wall mounted touch sensitive Smart Scene plates, enabling scene control of individual luminaires or groups of luminaires.

In some cases it can be time-consuming and costly to make interconnections between luminaires, for example in surface mounted retrofit installations, or in external areas such as open car parks. Thorlux has therefore developed the Smart System further, to its next generation, and now provides the option of full wireless control between Smart luminaires. This new enhanced system, patent granted June 2014, is named Smart TR.

How Does Smart TR Work?

Wireless Smart

The factory fitted addition of a Smart TR transceiver, to a Thorlux Smart luminaire, introduces the latest “mesh” wireless technology and replaces the wired Motionline communication signals between luminaires with sophisticated, trouble free wireless transmissions.

Each transceiver can be individually programmed with a Smart Programmer, during commissioning, and assigned to work exclusively within a particular building, or group created within that building. It is also possible to create situations where different parts of a building communicate – for example, when presence is detected in the offices, the corresponding corridors or staircases can be kept illuminated.

Smart TR uses 868MHz secure radio communication chosen for its excellent transmission distance and object penetration, especially useful within buildings. Each luminaire acts as a wireless node, repeating each command received onto the next luminaire, providing a robust system that will always find a communication path.

Smart TR Features

Operation Frequency

Operational frequency 868MHz, which is a relatively long wavelength compared to the more common 2.4GHz systems, therefore provides greater distance and penetration of signals.

868 MHz Wavelength
2.4 GHz Wavelength
Less than 1%

Intelligent algorithm with low transmission of data – transmits less than 1% of total time (99% of time wireless is off) – reduces wireless traffic increasing reliability.

Mesh Network

Mesh network – data can be transmitted from one device to another ensuring high signal reliability.

Good connectivity

Good connectivity – software uses simple wait before transmit logic to ensure error free transmissions.

Smart Programmer

Smart Programmer used for commissioning – simple, fast, individual, setting of operational parameters from ground level.

Smart System

Available in most Thorlux Smart fittings, including the Smart External range – seamless introduction of wireless communication to a Smart System.

Made in Britain

Designed and manufactured by Thorlux in the UK – a one stop shop for luminaires, controls and connectivity.

How Does Smart TR Prevent Cross-Talk Between Different Groups?


Each Smart TR module can be addressed to suit its application. The following parameters are programmable:

Building Address Icon

Building Address
Identifies devices that are within the same system and forms the boundary for the wireless mesh to prevent adjacent buildings communicating.

Group Address

Group Address
The control group, all luminaires with the same building address and the same group address will work together for presence detection and scene control. Up to 254 different zones can be created in one building.

Link Address

Link Address
Allows presence detection communication signals to be transmitted between different groups of luminaires. Each group can be set to transmit or receive an independent link address enabling occupancy in one area to keep another linked unoccupied area illuminated.

Internal & External Installations

Internal Installations

If any one Smart TR luminaire detects movement all luminaires within the group will illuminate. This valuable feature is designed to eliminate the possibility of a user being isolated in a small pool of light, surrounded by intimidating darkness. The Motionline ensures that there will always be a well lit comfortable environment.

External Installations

Highly efficient LED luminaires can be easily controlled by the exterior version of Smart - Smart External, but the cost of installing a buried cable to carry Motionline can be prohibitively expensive.
Smart External TR reduces cost by providing wireless transmission of the Motionline signal between luminaires.

When to Select Smart TR?

The Smart System is designed to work “out of the box” stand-alone, or to automatically work in groups when wired together using the Motionline. The Smart System is amazingly simple to use and install. Smart TR adds wireless connectivity to the Smart System and should be selected when luminaires are difficult to wire together into groups - for example luminaires mounted within a concrete staircase where channelling the walls to lay Motionline cables would be time-consuming and intrusive, or in an open car park where digging trenches to lay cables would be expensive. In recessed ceiling applications we continue to recommend the use of the Motionline wired connection provided by LCM interconnecting cables as this method will provide the most cost effective and simplest solution.

Smart TR must be commissioned as it has to be assigned Building Addresses and Group addresses. Commissioning is extremely simple using the hand held Smart Programmer (catalogue number LCM 10777B) or Thorlux commissioning engineers can complete this task for you.
