Description
Summary:Efficient lighting is a goal for energy efficiency and sustainable development. There are designs for electrically powered public lighting fixtures with solar panels installed in hard-to-reach areas or protected areas without an electrical power supply network. In this paper, a LED luminaire has been modeled by solving the heat equation using a heat source (LED 50W) to observe its behavior. The simulations were developed at ambient temperatures of 24°C and 35°C. It is important because these luminaires are installed in areas with this usual temperature, for example, the Ecuadorian Amazon or the Galapagos Islands. 51.7°C was obtained in LED for an ambient temperature of 24°C, which is the normal laboratory case, and 62.5°C in LED for an ambient temperature of 35°C. These results must be analyzed since it has a direct impact on the expected life of the luminaire and therefore on the maintenance and replacement plans. Through the results obtained, it was determined by Arrhenius model a reduction of 160 days in the maintenance plan.
