Application of LED technology into public road lighting in Malaysia for replacing the high pressure sodium vapour lighting

Abstract: The ‘Light Emitting Diode’ (LED) is not a new technology, however, it is used widely in many related products and being adopted in our daily life. However, for the street lighting system, LED technology is not fully accepted at the moment to replace the ‘High Pressure Vapour Sodium’ (HPSV) street light which has been used throughout the country. Due to sudden increment in operating costs and energy supply tariff, this technology starts to gain its consideration because of its ability in saving the energy. The street lighting system involves relative complex specification especially in terms of safety, therefore, the LED street light is still at its initial level. In Malaysia, the first pilot project in implementing the LED street lighting system was installed at federal road with 6-lane dual carriageway by the local authority. The pilot project focuses on the structure of the road and the on site lighting measurements. The aim of this paper is to study on the ability to identify whether the LED street lights can meet the specification requirements mentioned in MS-825. As a result, the comparison is made between HPSV and LED street lights are capable to satisfy the specification requirements. In addition, from the ‘Return on Investment’ (ROI) shows that the paybacks can be achieved within 5 years which under warranty period by the manufacturer or supplier. This proves that the proposed of replacing HPSV with LED street light is reasonable.

System for controlling streetlight and remote controller thereof

Abstract: PURPOSE: A lighting pattern control system and remote control equipment of a street light are provided to enhance energy efficiency by separately controlling a main street light and a second street light. CONSTITUTION: A lighting pattern is set in main street lights(M1,M2,M3). The main street light transmits and receives a lighting control signal through local area wireless communications. Secondary street lights(N1-N7) are turned on by receiving the lighting control signal. The secondary street light transmits and receives the lighting control signal with a neighboring street light. A power supply supplies a driving power source. A GPS(Global Positioning System) receives a satellite signal from a satellite and creates and outputs time and location information. A moving object sensing sensor senses a moving object and outputs a moving object sensing signal.

Street Light Outages, Public Safety and Crime Attraction

Abstract: For more than one hundred years, street lighting has been one of the most ubiquitous capital investments in public safety. Prior research on street lighting is largely limited to ecological studies of very small geographic areas, creating substantial challenges with respect to both causal identification and statistical power. We address limitations of the prior literature by studying a natural experiment created by short-term disruptions to municipal street lighting. We leverage a natural experiment created by the differential timing of the repair of nearly 300,000 street light outages in Chicago. By conditioning on street segment fixed effects and focusing on a short window of time around the repair of a street light outage, we can credibly rule out confounding factors due to area-specific time trends as well as street segment-level correlates of crime. We find that outdoor nighttime crimes change very little on street segments affected by street light outages, but that outages cause crime to spill over to nearby street segments. Effects are largest for robberies and motor vehicle theft. Despite strong environmental and social characteristics that tend to tie crime to place, we observe that street light outages are sufficiently salient to disrupt longstanding patterns. While the impact of localized street light outages can reverberate throughout a community, the findings imply that improvements in lighting can be defeated by the displacement of crime to adjacent spaces and therefore do not necessarily suggest that localized investments in municipal street lighting will yield a large public safety dividend.

Smart Street Light Using Hybrid System

Abstract: Street lights have become part of our everyday life which are becoming smartest. Now a days most of the system are replaced with LED lamps and various technologies like automation and communication based on the sensors in order to make an energy efficient and smart system. This paper provides an optimum solution for the smart functions of the street lights. Green energy harvesting seeks to supply power without a grid connection to electrical or electronic networks. The collection of thermoelectric energy depends primarily on the activity of the thermoelectric generator (TEG). Here, we plan to produce electrical energy from non-biodegradable waste by burning it and also to take energy from piezo electrical sensors. So here, to light the street light, we plan to produce electricity from waste materials, solar, foot power and store electricity in the battery.

Effective street light automation by self responsive cars for smart transportation

Abstract: A smart city is the global development vision to integrate multiple information and communication technology (ICT) solutions in a secure and simple way to manage a city's assets. Smart transportation is the basic component in future smart cities. Thus we are concentrating on the street light automation by detection of motion of object. Lighting which is not necessary can be neglected by targeted dimming of area of the city, town, roads or individual luminaries. The main objective of street light automation is to reduce the power consumption occurring due to lightening of street light during night when there is no objective motion on the street. During day time, the lights will be turned off and during night it will be turned on. In street light automation we are using Pulse Width Modulation (PWM) technique to control the light intensity in different condition like day, night, no vehicle condition & vehicle condition. In this paper we are working on street light automation by means of self responsive cars with collision avoidance system.
