Energy efficiency and light management

Sustainable lighting solutions

TRILUX makes a very decisive contribution to climate protection and sustainability with its products, because powerful LED luminaires and intelligent light control systems are the basis for lighting solutions with high quality of light, an exemplary energy balance and a long service life. In this regard, climate and resource protection are inherent in TRILUX's core business.

Halving energy consumption with LED light sources

Lighting energy accounts for about 19% of total global energy consumption.  In terms of volume alone, therefore, there is great sustainability potential waiting to be tapped. The lighting industry has a particularly effective instrument for this purpose in the form of light-emitting diodes (LEDs) in general lighting. Current LED light sources have a luminous efficacy of up to 200 lm/W. For comparison: in an incandescent lamp this value was up to 30 lm/W, the latest generation of fluorescent lamps achieves about 100 lm/W. There are projections stating that in 2017 alone, over half a billion tonnes of CO2 emissions could be avoided by converting old lighting systems to modern LED technology. 

TRILUX has largely converted its luminaire portfolio to LED technology and, thanks to ongoing research and development work, keeps on top of the rapid pace of innovation in the LED industry. As a result, lighting systems can be realised with TRILUX luminaires that consume only half as much energy or even less compared to conventional lighting technology – with equivalent or better quality of light. In addition, these luminaires feature other sustainability genes, including their long service life of more than 50,000 operating hours and much longer maintenance cycles. This way, LED technology provides several sustainability trumps at once.

Controlling light according to requirements

However, LED technology is not only a true efficiency innovation because of its high luminous efficacy – it has also established the foundation for the digitalisation of light since LEDs can be switched and dimmed very conveniently. In combination with sensors and electronic control and communication modules, intelligent light management can be realised. For example, the light is switched and dimmed depending on presence (persons, vehicles, etc.), corresponding to the available daylight or simply according to a suitable time schedule. As a result, the lighting is only switched on when it is actually needed and then does not always provide the maximum level of brightness, but always a level of brightness adapted to requirements. Lighting solutions with LED light sources controlled according to requirements by a light management system can achieve energy savings of up to 80% compared to a system with conventional light sources and simple on/off operation.

LiveLink provides TRILUX customers with a freely scalable light management system for implementing sustainable and cost-efficient lighting solutions with ideally controlled, individually adapted light. The system makes it possible to plan and operate even the control of complex lighting systems in a simple way, and it is suitable for almost any application area. In particular, commissioning, which is considered one of the greatest challenges in light control systems, is carried out effortlessly via an intuitively operated graphical user interface and preconfigured scenarios. This way, the potential of a digital lighting solution can be safely tapped with minimal effort and without risk.

Intelligent light can achieve even more sustainability

Once luminaires are connected via a light management system, it is an obvious next step to not only submit control commands from the controller to the luminaires, but also to transmit, store and use data from the luminaires the other way around. Intelligent lighting networks of this nature with bidirectional communication enable numerous services, each of which offers opportunities for greater sustainability, for example:

Energy Monitoring

Recording and analysing the energy consumption of each individual light point in a system can be used to identify hidden energy saving potentials. Detailed consumption data also create comparability between different plants or properties and thus offer possible approaches for optimisation.

Predictive Maintenance

Knowing the precise operating data of luminaires makes it possible to optimise maintenance and servicing. Instead of rigid inspection and maintenance intervals, it is possible to act just-in-time and as needed – and to do so with foresight, because operating parameters such as power consumption or temperature are good markers for the condition of a component. Blanket, plant-wide replacement of spare parts after a defined operating period is no longer necessary. Instead, replacements can now be made as necessary. This keeps intact lamps and assemblies in operation longer, saving resources. Since all data including location identification is centrally accumulated for each individual light point, maintenance teams can address the luminaire directly and on-spec inspection trips become obsolete, which noticeably reduces the amount of travel and thus resource consumption and greenhouse gas emissions.
