According to a policy report submitted before the conference last Friday, Chennai, India has installed 48,034 energy-saving LED street lights in the city, setting a historic record. According to the policy report, the LED street light required for the project will cost 101,000 rupees, and after expanding the field, it will cost 3.22 billion rupees. So far, the city has 48,034 LED street lights that have replaced CFL bulbs and aged sodium lamps on internal roads and traffic lanes. According to the report, it is worth mentioning that no other municipal company will install such a large number of LED street lights like Chennai. As of March 2016, the remaining 61,966 street lights will be fully installed. It is reported that LED street lamps consume about 40% less electricity than sodium vapor lamps. Chennai maintains 248,467 street lights in the city. These street lamps consume about 19 MW per month and cost the company about Rs 2 crore a year. Nearly 15,000 street lights work fine every night. The company did not receive complaints about the breakdown of street lamps, and more complaints about the dangers of stray dogs and improper disposal of garbage.

A Linear Power Supply is an electronic device designed to provide a precise and stable DC voltage output from an AC input. It utilizes a linear regulator to maintain a constant output voltage despite variations in input voltage or load current.
Working Principle
Transformer Stage: The AC input voltage is first stepped down by a transformer to a lower AC voltage level.
Rectification: The transformed AC voltage is then converted into pulsating DC voltage through a rectifier circuit, typically using diodes.
Filtering: A filter circuit, often consisting of capacitors, removes ripple from the pulsating DC voltage to produce a smoother DC output.
Regulation: A linear regulator adjusts the output voltage to maintain a precise and stable level, despite changes in input voltage or load conditions. This is achieved by dissipating excess power in the form of heat.
