Abstract
Street lighting with LED technology is currently the main option of public lighting in almost every country. Even though LED technology is a less costly selection, there needs to be well planning in an attempt of acquiring high efficiency. Photometric approach was tested in this study in order to redesign the existing approach used in the street lighting in Indonesia. The redesigning process was carried out using a software namely DIALux on two different schemes; one with homogeneous luminaire and the other one with non-homogeneous luminaire. The results of this study showed that the most significant factors in redesigning street lighting covered types of the lamp, pole distance, pole height, and proper lighting angles which could affect the illumination value on both the main road and the sidewalks. In addition, it has also been proven that homogeneous approach using LED lamps lighting uniformity as well as optimum illumination. Therefore, it is recommended that further studies focus on LED selection from different brands and its impact to energy efficiency and life cycle of the lamps selected.
