| Summary |
"The present study demonstrated lighting loads as an energy end use associated with renewable energy system applications. Incorporating an energy efficient end use within a renewable energy system can be especially beneficial regarding size and portability. Light-emitting diodes (LEDs) are an energy efficient alternative to traditional outdoor lighting, which is currently dominated by high intensity discharge source lamps. LEDs provide the ability to mitigate the negative impacts of diesel consumption when a diesel generator is used independently or as a backup for renewable energy applications in remote localities. In-field data was collected of traditional metal halide lamps and two comparable LED luminaries in order to evaluate photometric characteristics and the energy consumption requirements regarding diesel generation and energy storage. An energy efficiency analysis, including diesel generator consumption tests and charge/discharge tests with batteries and ultracapacitors was performed with the various lighting loads. The LED outdoor lighting performance was found to be unsatisfactory in terms of required illumination for construction-related and other high-risk applications. However, the LED lumiaires [sic] performed at an acceptable level of illumination to meet the minimum illumination standards of security and roadway lighting applications. The energy saving capabilities of LEDs, as well as the inability of LED options within today's lighting market to meet illuminance equivalence with traditional lighting options were reinforced within this study"--Abstract, leaf iv. |
