PILG -
PHOTINUS INTELLIGENT LIGHT GUARD
The intelligent use and control of light is one of the latest developments in lighting. Due to this method we counteract the increasing lighting pollution as well as energy waste. Photinus opens up entirely new possibilities for the use of solar luminaires. It is possible to achieve the same light output / light intensity compared to electrified street lighting.
HOW DOES DEMAND RESPONSIVE LIGHTING WORK?
A new bicycle track with 10 light fittings should provide more safety for users. Based on the given facts and demands the light will be switched off or remains in a basic dimming mode (starting from 10 % to any percentage up to 100 %) as per requirements. When the user (cyclist, pedestrian etc.) approaches the 1th luminaire that one and the next 2 luminaires will be tuned up to 100 %. As soon as the user reaches the second luminaire the 4th one will be tuned up, when the user reaches the 3rd luminaire the 5th one will be tuned up and so on. The number of the “neighbour luminaires” and the illuminated time can be set individually. It is called moving light as the light is moving along with the user.
HOW DOES THIS TECHNOLOGY WORK?
With the intelligent PILG controller from Photinus, wireless communication between the individual solar luminaires is possible. This means that the light can be tuned up only when needed hence reducing the overall energy consumption to a minimum. The complete lighting system can be controlled in real time with an optional GPS sensor on one luminaire only.
ADVANTAGES OF THIS INOVATIV SOLUTION!
This unique technology provides the client with multiple benefits:
Safety: by tuning up the light which only happens when passing the area the energy saving effect is up to 70% compared with full operation at 100%. This saved energy can be provided on demand at 2 to 3 fold light intensity. This highly increases the sense of safety.
Costs: The overall costs for the client will be considerably reduced by the following arrangements:
- the number of luminaires can be reduced by about 35%. This means for a bicycle track of 1 km length the pole distance can be increased from 35 m to 50 m and therefore the number of luminaires can be reduced by 10 pieces
- in this case the same lux levels from the same luminaire can be achieved
- because of the reduced number of solar luminaires also the installation costs will be considerably lowered.
