Performance of LED lights installed on DKI Jakarta streets (Case study on Pattimura street & Satrio street, South Jakarta)

Abstract

This research analyzes the performance of LED lights installed on Pattimura street, which are in front of PW building, in front of Al-Azhar building, and in front of house compounds, and on Satrio street, which are in front of and across CityWalk Mall and across Ciputra World I building. The testing is done by measuring the illuminance (the unit is lux) with luxmeter on the measurement zone which has certain measurement points. The LED lights on Pattimura street have power of 237 watt, light distance of 50 meter, pole height of 9 meter, and street width of 6.9 meter. The testing result shows that the lighting on street surface is SNI compliant, which means the LED light can be used for street lighting. But there is high illuminance on measuring point which is perpendicular to light and it means light pollution. On the contrary the illuminance decreases significantly on the zone between the light pole and it is not SNI compliant. For this reason, the distance between light pole and the light power should be decreased. The result also has the isolux drawing and it is designed with Dialux software. The branches of trees on both streets cover the light so that the illuminance of street surface decreases. And this matter should be handled by DKI Jakarta government.

Design Lighting Quality Based on DIALux Evo 8.1

“…This research discusses the outdoor lighting system. The results of this study indicate that LED lamps are not suitable to be implemented directly with existing light poles and the spacing specifications of the lamppost and the lack of planning in adjusting the spacing of light posts that varies between 40 meters to 52 meters [3]. Based on problems and related research, then to improve lighting quality, this study will design lighting systems in classrooms based on established standards using two calculation methods, namely the lumen method as a manual lighting calculation and the DIALux Evo 8.1 as software.…”

“…Luminous flux Luminous flux emitted by a light source is all light emitted in every second [2]. The unit of luminous flux is lumen (lm), and the luminous flux is expressed by equation 1 [3].…”

“…Luminous Intensity Luminous Intensity is the strength of the light source and is measured by candela [3] and expressed by equation 2 [4].…”

“…Luminance is a measure for the light of an object's surface. To calculate the luminance expressed by equation 4 [3].…”

Analysis of the visual safety perception and the clarity of traffic signs and road markings in the presence of road lighting in straight and curved road

“…The results indicate the presence of uneven illuminance on the road surface, and less or excessive illumination according to the road lighting standards [3][4][5]. This study provides an overview of car drivers' perceptions to the road lighting, in relation to safety and clarity in identifying traffic signs and road markings.…”
