Energy Saving Smart Dimmable LED Street Light developed by CMERI ,Durgapur as a part of “Make In India “
Street Lighting plays critical important role in modern urban & rural human habitations .
It provides us safety and an assistance to mobility during the dark
hours. Different street lighting systems are used on high way or in
internal network of roads in any human habitation , but all of them
face the identical challenges − high consumption of
electricity and difficulties to identify the faults of lighting
network.
Scientists of CSIR-CMERI developed an affordable technological solution
that saves significant amount of energy along with easy identification
of faults in street lights named −Smart Dimmable LED Street Lighting
Technology. The key feature of the technology
is that it automatically increases the brightness of street lights when
a pedestrian or bicycle or car is moving or present in the street and
goes back to predefined dimming state when none is present. The
technology works in combination of the advanced motion
sensors with dimmable LED drivers that makes on-demand dynamic lighting
through adjustment of intensity of individual street lights that can
vary from 10% to 100%. It softly enhances the brightness of forward
lights so that the pedestrians or bicycles or cars
get enough light well in advance. This ensures safety and comfort of
pedestrian. Additionally, it automatically switches ON the street lights
in the evening and OFF in the dawn, without the need for human
intervention. Further, it is tolerant from undesirable
trigger in light demand when animals such as cats, dogs etc.,passes by.
Prof. Harish Hirani, Director, CSIR-CMERI, informed that CSIR-CMERI has
already deployed this technology in CSIR-CMERI’s residential colony by
converting 50 numbers of LED based street lights into energy efficient
smart street lights, and it was observed during
the trials that up to 60% energy savings is possible compared to the
conventional LED based street lights.
Prof. Hirani further added that it has a feature to automatically
identify the faulty street lights and alerts the maintenance engineer
through SMS. This feature greatly reduces the need for visual
inspections and saves significant amount of time of the maintenance
engineers. This technology is configurable to work in standalone as
well as in networking mode and can be combined to work with CSIR-CMERI’s
Solar Tree Technology.
The Smart
Dimmable LED Street Lighting Technology has great potential market not
only in India but in every nation across the planet . It can play
important role in management of energy expenses
of municipalities , panchayats , ports , cantonments across India .
It plays
important role in fighting climate change as well as promoting United
Nations ‘s SDG by lowering carbon footprint .
CSIR-CMERI has transferred the Smart Dimmable LED Street Lighting
Technology to M/s Koley Engineering Works, Howrah, West Bengal on 21
September 2019.
