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

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.
