TL;DR: In this paper, the authors proposed an intelligent and energy-efficient traffic sensing system based on the widely distributed street lights, which is intended to observe vehicle's movement on the road and turn ON a block of street lights ahead of vehicle whenever needed.
Abstract: The huge amount of electric power and cost associated with street lighting has raised the need to investigate both cost
issues and environmental concerns. Cities worldwide are increasingly investing in energy-efficient street lighting systems.
Modern street lighting technology can lower energy consumption as well as operation and maintenance costs significantly.
In addition, bright street lighting can reduce accidents and crime rate in the area. Street lighting is an essential public
service that provides a significant factor contributing to the quality of life and productivity of people workforces. This paper
proposes an intelligent and energy-efficient traffic sensing system based on the widely distributed street lights. It is intended
to observe vehicle’s movement on the road and turn ON a block of street lights ahead of vehicle whenever needed. As the
vehicle passes by, the system turns OFF the trailing lights. The brightness (intensity of light) of the street light is adjusted
based on the surrounding using LDR sensor. Hence, the street lights will be switched ON in the evening around sunset when
a vehicle passes by, and switched OFF in the morning after sunrise when there is sufficient light on the streets. In addition,
the proposed system will control the intensity level of the street light using the LDR sensor. The Proteus Software Simulation
of the proposed system was performed and tested. Then a hardware prototype was designed and implemented to evaluate
the performance of the proposed system. This technology can save significant costs and energy.

TL;DR: In this article, a system consisting of a controller 3 installed as an input apparatus; a storage battery 4; a solar panel 5; an outage time LED light 6 installed as output apparatus; and an existing security light/street light 7.
Abstract: PROBLEM TO BE SOLVED: To provide a backup power supply automatic switcher against long outage of a security light/street light.SOLUTION: A system comprises: a controller 3 installed as an input apparatus; a storage battery 4; a solar panel 5; an outage time LED light 6 installed as an output apparatus; and an existing security light/street light 7. Control with the controller 3 makes the outage time LED light 6 turn on when power supply from a commercial power supply 1 stops in disasters or the like. Changeover to the system having power consumption lower than that of the existing lighting reduces power consumption and extends a backup period. The controller 3 makes changeover of lighting to the existing security light/street light instantly after the power supply from the commercial power supply is restored.

TL;DR: In this paper, the authors proposed a smart street light control system and method, which may control illumination of a road according to a road condition by updating a road lighting rating preset when designing or constructing the road to a new road lighting ratings depending on the road condition during use of the road, and controlling a dimming value of the street light according to the new street lighting rating.
Abstract: The present invention relates to a smart street light control system and method, which may control illumination of a road according to a road condition by updating a road lighting rating preset when designing or constructing the road to a new road lighting rating depending on the road condition during use of the road, and controlling a dimming value of the street light according to the new road lighting rating. Accordingly, energy efficiency can be improved by minimizing an unnecessary waste of energy while realizing an optimal road environment.
