This paper aims to improve the implementation standards of solar-energy-based street lighting in Indonesia. A model framework was developed to assess existing conditions regarding the level of lux, the distance between poles, pole height, and lamp power. According to the evaluation of the existing circumstances, the street lighting system is not satisfactory according to the national standard, with 64.7% black area. An alternative installation of street lighting designed by DIALux application was proposed to fulfill the technical standard of street lighting. The result shows that this alternative design can be used for renewing existing street lighting with better performance and reliability. Economic analysis of all technically feasible alternatives was conducted afterward by benefit–cost analysis. The analysis shows that solar-energy-based street lighting requires as much as 621,473,620.00 Indonesian Rupiah (IDR), with 1.06 benefit–cost ratios and a 9% reduction of total cost. Therefore, the analysis indicates that solar-energy-based technology can be feasibly implemented in a street lighting system. The results show that the proposed model can be applied to improve the implementation standard of solar-energy-based street lighting.

The objective of this research is to propose an Artificial Intelligent method to optimize the performance of street lightings. The method proposed in this research is by using the Electromagnetism-Like Mechanism (EM) global optimization algorithm. The proposed EM is designed to minimize the power consumption and maximize the life span of the lamps by different switching configurations and by adjusting the intensities of the lights. Simulation results indicate that the proposed algorithm can significantly reduce the power consumption of the system and drastically increase the projected life span of the lamps used. The main power savings can be found in the early stages of the graph. This shows that the evening sun rays and twilight help illuminate the street, rendering full intensity of street lights a waste. This, in turn, significantly prolonged the lifespan of the lamps used in the street lightings. It can thus be concluded that the proposed algorithm gives significantly positive impact in optimizing the performance of a street lighting system. The search speed and accuracies of the EM can be further improved by modifying or incorporating other search mechanism into the EM in future extension of the research.

“…Light-emitting diodes (LEDs) have become widely available in various industrial fields concerned with energy saving and offer positive environmental effects due to their advantages over conventional light sources, such as low power consumption, long lifetime, rapid response time, compact physical size, and physical robustness [1][2][3]. In particular, in order to reduce indoor lighting energy use, which accounts for nearly 30% of the total energy use in buildings, high-efficiency LED lighting and daylight dimming control technologies have been developed [4][5][6].…”

Savings in Cooling Energy with a Thermal Management System for LED Lighting in Office Buildings

Light-emitting diode (LED) lighting should be considered for lighting efficiency enhancement, however, waste heat from light-emitting diode (LED) lighting increases the internal cooling load during the summer season. In order to solve this problem we propose a thermal management system for light-emitting diode (LED) lighting with a heat exchanger module integrated with the building's heating, ventilation, and air conditioning (HVAC) system to move the lighting's waste heat outdoors. An experiment was carried out to investigate the thermal effects in a test chamber and the heat exchange rate between the heat sink and the duct air. The heat generated by the light-emitting diode (LED) lighting was calculated as 78.1% of light-emitting diode (LED) input power and the heat exchange rate of the lighting heat exchange module was estimated to be between 86.5% and 98.1% according to the light-emitting diode (LED) input power and the flow rate of air passing the heat sink. As a result, the average light-emitting diode (LED) lighting heat contribution rate for internal heat gain was determined as 0.05; this value was used to calculate the heating and cooling energy demand of the office building through an energy simulation program. In the simulation results, the cooling energy demand was reduced by 19.2% compared with the case of conventionally installed light-emitting diode (LED) lighting. OPEN ACCESSEnergies 2015, 8 6659
