Agregar Etiqueta | Sumario: | In the present final degree project the design and analysis of a system of external illumination by means of technology LED, was carried out which is energized by means of concentrated photovoltaic generation. Considering that, in the parking lot, there is an average illumination lower than the permitted, levels, it was proposed to improve the lighting through the Dialux evo software, obtaining the following results from this design: 518 lx for access, 132,83 lx in the circulation strip and 113,75 lx in parking spaces, in accordance with the NTE INEN 2248 standard, whose electric power density for lighting is 1,88 W/m2. Through a bibliographic research, the technical data of the LED luminaires of 245 W and 134 W were compiled, with a luminous efficiency of 145 lm/W and 146 lm/W respectively. In addition, the photovoltaic system consists of 28 monocrystalline panels of 360 W/24 V, the accumulation system will consist of 28 deep discharge batteries at 240 Ah/12 V, two PWM load controllers of 110 A/48 V and the inverter of 5000 VA/48 V. With a new value for the kWh of USD 0.6812 it is possible to have a VAN of $ 66.525,60 and the TIR equal to 25,35 %, indicating that the project is profitable. In conclusion, using LED technology, an efficient lighting system is obtained, which together with the photovoltaic system, contributes to the environment care. |
