A comparative analysis study on the electrical characteristics and photometric performance of light emitting diode street lights for power utility in Malaysia / Nor Diana Ruszaini Mohd Zin

Recently, a rapid development technologies Light Emitting Diode (LED) in street
lighting has recently developed and rapid development has continuously develop due to
its character of better energy efficiency, long lifespan and robutsness. The new street
light technology is developed as alternatives to High Pressure Sodium Vapour (HPSV)
street lighting. In this research study, the aim is to study the photometric performance
and electrical characteristics of LED Street Light in comparison to HPSV Street Light.
This includes of its, photometric quality, electrical characteristics of the LED Street
Light, and its energy saving. The study involves installation of 128 unit of LED street
lights at site, measurement of its photometric performance and electrical characteristics
at site. There are eight LED street lights technologies sourced from several
manufacturers with variance of their technologies and design installed for this research
study. From the study, it is found that LED Street Light is technically viable to replace
to HPSV Street Light, though in this research, it is found that not all LED Street Light
technologies comply to the requirement of Road Lighting Classification. It is also
indicated that LED street lights can offer in between 23% to 58% energy saving. From
the study, it shows that 3% failure rate for the first year of installation which is lower
than HPSV Street Light failure, thus, shows that LED street lights requiring fewer
repairs.
