Four Tridonic recommendations with huge potential savings

Modern LED outdoor lighting


When it comes to renewing street lighting in towns and cities there's no getting away from LEDs. We'll show you the technologies that will let lighting systems pay for themselves in the shortest possible time and how you can improve ROI still further.

Towns and cities looking to renew their street lighting are opting for energy-saving LED luminaires. In addition to impressive economy they offer the necessary flexibility to meet the requirements of the EN 13201-5 standard and the individual requirements of the local communities. And yet their potential is often only half-heartedly exploited. We therefore present four technologies that will help you save even more energy and money and therefore increase ROI still further – with optimum light in terms of aesthetics, orientation and safety.
 

1. Adjustable current

A major benefit of modern outdoor luminaires with Tridonic LED Drivers is that they can be very easily adjusted and controlled. This is particularly useful if the light beams from multiple luminaires overlap one another, for example at road junctions and entrances. In such cases the lighting level of the luminaires can be reduced by adjusting the output current for individual luminaires.
 

2. CLO – Constant Light Output

The longer a LED luminaire is in operation the more energy it needs to produce a constant level of light. Up to now, the luminous flux was either set too high initially, which meant the illuminance was higher at the start than was actually required, or set at the right level, which meant that the illuminance was correct only at the time of commissioning. Neither approach was ideal and had an adverse effect on economy or even safety. The solution is to find LED Drivers that regulate the luminous flux intelligently and automatically. This ensures a constant lighting level throughout the entire lifetime and therefore economical operation.
 

3. chronoSTEP – night time power reduction

Why consume energy when there is really no need? In the middle of the night there is far less activity in a city than in the early evening. The solution: thanks to intelligent LED Drivers the power supplied to individual luminaires or groups of luminaires can be automatically reduced during the night to dim the light and thus save energy – without compromising on safety.
 

4. corridorFUNCTION – always on call

Dimming of luminaires makes sense from the point of view of energy consumption but cannot always be put into practice because of safety considerations. It becomes economically interesting if the luminaires can react automatically to changes in their environment and regulate the lighting level themselves. This can be achieved with sensors that detect movement and increase the illuminance levels accordingly or, after a suitable delay, decrease them to a predefined minimum.
