The present invention generally relates to a street light automation system comprising automatic on-off and step dimming control provisions for specially designed LED based street lights. Said street light automation system particularly include plurality of street lights, installed in a particular stretch of street or highway, wherein each of the street light comprises plurality of LEDs, divided in at least two groups, characterized in provisions of selective switching-ON or switching-OFF or dimming of at least one group of said LEDs, controlled in time relation through wirelessly connected PLC based control mechanism of the said street light automation system of the present invention. Said automation system of the invention is also provisioned sensing the natural light and accordingly automatically switching-ON and switching-OFF of all the street lights, wirelessly connected to the controller means of the said automation system. The present invention effectively performs its role towards reducing consumption of electricity.
Background of the invention and prior arts:
Conventionally street lights are controlled either manually or in automatic manner. These days automation of street lights are gaining much importance in every constructional work assignment, as saving of electric power is very much important now. It can be observed that there is no need of high intensity of light in a large duration of night time, particularly when no or very little vehicular movement is observed on the street. It is generally observed that in night, there may not be any traffic after midnight, even in early mornings.
By reducing the intensity or dimming the street lights in these times, energy can be saved to considerable extent. There are many methods to save the power like Switching the street light on detecting vehicle, Street light controlling using LDR and relays etc.

One exemplary system for dimming the street lights comprises circuits of Figure-1, wherein it controls street light intensity by calculating the peak hours, wherein it also includes street light controlling using PIC microcontroller. Most commonly found street lights are HID or High Intensity Discharge lamps, which consume a lot of power. In order to save energy, the circuits are designed with high intensity LEDs in place of HID lamps.
The patent document US20130057158A1 discloses a method and apparatus for controlling a streetlight is provided. GPS data is required from a GPS coupled to a process of the streetlight. A geographic location of the streetlight is determined from the received GPS data. A real local time is determined from the GPS data and a sunrise and sunset time associated with the geographic location can then be determined. Said prior invention also discloses a streetlight controller comprising a global positioning system (GPS) dimming module comprising: a GPS receiver; a processor coupled to the GPS receiver for acquiring GPS data from the GPS received determining in a processor a geographic location and a real local time from the GPS data to determine a sunrise and sunset time associated with the geographic location; a LED control interface for controlling a on and off state of one or more LED lighting modules of the streetlight based upon the determined sunrise and sunset times. The on and off state of one or more LED lighting modules of the streetlight can then be controlled upon the determined sunrise and sunset times.
Another Korean patent document WO2014209002A1 relates to a method for controlling dimming of a street lamp to reduce power consumption. In the method for controlling the dimming of the street lamp, the street lamp comprises a plurality of illumination units, of which dimming can be individually controlled, and at least one illumination unit among the plurality of illumination units has a power amount smaller than that of another illumination unit. According to the present invention, a plurality of LEDs included in a street lamp are randomly divided according to the direction of progress of a vehicle and dimming of the divided LEDs

are controlled with different levels, so that luminance degradation felt by a driver on a road can be minimized. As a result, the present invention can save energy and solve inconvenience to the driver. In the street lamp, a plurality of illumination dimming control is possible, wherein it receives supply of power, according to the control of the controller and power supply unit for dividing the power delivered to the lighting unit of the plurality, and the power supply is based on a set criteria, street lamp comprising a controller that controls so as to divide the power transmitted to the operation of the plurality of illumination units.
Even though several prior arts and common knowledge for putting street lights on automation towards controlling its ON-Off and its dimming functions are available and are being practiced, there is still ample scope for creating a more advanced such automation system towards: (i) more efficient dimming function of street lights applicable on a pre-determined stretch of the street-road or a highway; (ii) highly cost-effective installation of equipments of wireless control panels and wired network of street-lights, which is highly durable and require least maintenance; (iii) involving least cost in the operation of the wireless control of ON-OFF and dimming functions of the whole street light network of the present system; (iv) saving huge amount of electricity by the said automation functions, (v) a highly environment friendly street-lighting system; and (vi) eventually making earning by way of the operational cost being paid-back by the present automation system.
There are no. of manufacture and suppliers available in market, who have been using one of these technologies viz Analog Dimming, Triac Dimming, DALI dimming, LoRa and Zigbee. All technologies have some advantages as well as disadvantage. However, evaluation criteria for any system is based on the following points as mentioned below:
• CAPEX
• OPEX

• Recurring cost
• Subscription cost involved (If any)
• Buy back period
• System Efficiency, Reliability & Long term scalability
Practically it becomes difficult to keep all above points under acceptable limits. It happens that if we opt for a system having all above parameters under control, the CAPEX cost usually increases and have significant recurring cost as well. Also few of technologies like Zigbee and LoRa are very new and less reliable as their stability are yet to be established in India. Also it involves recurring cost of server maintenance as they are usually deployed in cloud. Even if servers are locally deployed in client's premises, there is also a cost of their software maintenance.
Prime Objects of the Invention are:
• To provide a novel construction of the LED based street-light fixture, capable of being mounted on pole of street light, wherein said LED based street-light fixture comprises of plurality of LEDs, connected together through electric wires in suitably selected circuits and divided into more than one groups therein, preferably in two grouped;

As per one wild analysis, India has over 35 million street lights which generate a total demand of 3,400 MW. With LED, this can be brought down to 1,400 MW, saving 9000 million kWh of electricity annually, worth over $850 million in the process, which is a significant figure. Therefore, it is the object of the present invention, mainly by way of the novel and inventiveness involved in the invention, to save electricity, environment and cost-cutting, as under:
1. Energy Conservation: To obtain similar luminance as that of a 210 W LED light, the system of the present invention will require around 400W sodium vapor lamps (SV) or metal hydride (MH) fixtures. It means there is a straight away saving of 50% energy, however the present system moves one further step towards energy efficiency and preferably replaces conventional SV or MH by including LED based lighting fixtures on street lights. With the present construction of the street lighting system with automated On-OFF and dimming control mechanism, it is possible to further reduce electricity consumption, without compromising with the effective glow and light-intensity on streets in peak hours of night.

2. Grid offload when the lights are dimmed during night when there is minimal or no vehicular/people movement, an indirect energy conservation.
3. Maximum demand is at night which decreases causing a decrease in the load of transmission network & thus increase in the efficiency of Power Distribution System, an indirect energy conservation.
4. As the demand decreases, the transmission & distribution loss decreases and the saved power can be sold to commercial & industrial sector at lower prices thereby reducing the overall production cost and helps in keeping the inflation at lower end.
5. Reduction in the emission of carbon content to a huge extent by dimming the lights when it is not required.
6. Elimination of human intervention as the light switches On & Off automatically at dusk and dawn to avoid over-run of lights which in turns saves the extra energy consumption.

Street light automation system of the present invention has been designed and developed seeing the urgent need of efficient lighting control system with reduced installation cost, zero recurring cost and minimal maintenance cost yet reliable, communicable and fully scalable system.
The present system is bit different from what is depicted above about usual available systems in market on different technologies. The detail information and design is shared in step by step manner in this document. We would like to outline the basic features and operational philosophy of our Street Light Automation System.
System Write-up & Operational philosophy
The lights have been designed in a way so as to achieve our required target of On, Off and automatic step dimming control. In normal condition, the lights will be dimmed to 50%. As soon as the vehicle enters on road, the lights of that side of the road becomes 100% bright, to
10

enhance the visibility of speeding vehicles, while the other side of road remains in dimmed
mode. Once the vehicle is passed, again the lights will come to dimmed mode.
The system is a true combinations of Electrical, Instrumentation, Automation and Information
Technology. System is in operation at main entrance of our project site, Wave City, NH 24 and
can be witnessed in person after sunset.
Our system does not use any dimmable driver, independent micro-controller or communication
module for each pole/light neither does it uses any third party cloud based service which incurs
heavy recurring and subscription cost on account of using cloud services for maintaining street
light datas. We have targeted on keeping the CAPEX on a lower end, without increasing the
OPEX and keeping the recurring cost almost negligible by designing and developing our in-
house system.
We would like to underline the beauty as well as the advantages of our in house developed
system.
These are briefed below:
. Minimal cost solution. In-house design and development. No dependency on any
external agency. . Most efficient in terms of reliability and scalability with minimal maintenance cost and
negligible recurring cost. . Major focus is on energy conservation where we are saving substantial amount of energy bill which is an indirect saving for the company. Payback period of this system is significantly less than other available solutions. . Reducing the emission of carbon content to a huge extent by dimming the lights when
it is not required. . System installation cost is much less when compared to other solutions offered by different companies available in market.

The objective behind this concept is not just installing LED lights instead of conventional MH & SV lights to reduce electricity demand as quoted above rather to obtain much more than that which are underlined below, particularly with regard to the one preferred embodiment of the present street light automation system, which is under experimental trial and rigorous analysis towards its efficacy:
To obtain similar luminance as that of a 210 W LED light, we have to use 400W SV or MH fixture. It means there is a straight away saving of 50% energy, if we go with a LED light.
16

Further, with our designed system, the lights glows in full mode only when there a people or vehicular movement, else it remains in dimmed mode maintaining the required luminance on road and thus we are helping in 3 step energy conservation. First is on account of converting MH/SV lights to LED lights which saves approx. 50% of total energy demand. Second, when using LED lights, we have implemented the dimming concept and hence, for approx. 10 hrs, the lights glow in dimmed mode which is mere 25%. Third is automatic On/Off control where lights are made ON & OFF at Dusk & Dawn automatically with the help of dual photo cells and RTC installed in controller. We have tried to explain the energy consumption, savings and ROI against our executed project at Wave City, Ghaziabad
ROI calculations:
Total no. of lights = 104
210 watt-52 lights
120 watt- 52 lights
Total wattage= 10.92 + 5.72 KW = 16.64 KW
Average Consumption @ lOhrs/day = 16.64 x 10= 166.4 KWH/day.
So, total consumption per day = 166.4 Units
Considering 75% Dimming, units saved per day is 124.8 units
Net Saving in Money = 124.8 units @ Rs 6 X 365 equals 2.73 Lacs/Year
System installation cost is 3 Lacs. Net Saving is 2.73 Lacs/Year, hence payback period is 14
months only.
This system is implemented only in a small part of Wave City project. 10 similar systems shall
be installed in near future which shall save approx. 25 to 30 Lacs/year.
2. To add further on energy conservation part, we have listed out the areas which shall be
directly or indirectly impacted after implementation of system:

3. Grid offload when the lights are dimmed during night when there is minimal or no vehicular/people movement, an indirect energy conservation.
4. Maximum demand is at night which decreases causing a decrease in the load of transmission network & thus increase in the efficiency of Power Distribution System, an indirect energy conservation.
5. As the demand decreases, the transmission & distribution loss decreases and the saved power can be sold to commercial & industrial sector at lower prices thereby reducing the overall production cost and helps in keeping the inflation at lower end
6. Reduction in the emission of carbon content to a huge extent by dimming the lights when it is not required.
7. Elimination of human intervention as the light switches On & Off automatically at dusk and dawn to avoid over-run of lights which in turns saves the extra energy consumption.
