| Abstract | Street lighting plays the important role in every transportation area to enhance the safety and visibility. AIT has 333 street lights to supply the light for all streets at AIT. Currently, 320 of 333 street lights are in operation (96.10%) which operate 12hours a day, and all days a year. AIT’s street light resource comes from Fluorescent Tornado twist lamp and high pressure sodium lamp which consume the electricity 12 W and 85 W respectively. The share of lamp at AIT are 175 lamps for Fluorescent Tornado twist, 145 lamps for High Pressure Sodium and 13 lamps for non-operation. The estimation of illumination is obtained by DIALux software. The results claimed that only 3 of 26 roads satisfy the illumination and uniformity ratio standard according to CIE standard. AIT spends 23,133.45 Bath per month, and emits 3.02 ton CO2eq of CO2 emission. The improvement options are studied to reduce the electricity bill and CO2 emission. The option categories are classified into activity, auxiliary and luminaire. Benefits, limitations and costs of all options are listed. LED Street lighting and Solar LED street lighting present the promising options for AIT. This study shows that LED Street lighting can be substituted for all existing lamp at AIT. It can reduces 3,731.4 kWh per month, increases illumination at all street and has 11.4 years of payback period. For Solar LED Street lighting, it spends free of charge for electricity bill. The average illumination level is 7.98 lux in 3 meters area. The payback period of this lamps for replacing Fluorescent Tornado twist lamp and High Pressure Sodium lamp are 32.1 and 4.5 years respectively. |
