Modeling a Solar-Panel–Actuated Light Detection System for Multi-State LED Output
Doha GARAGUE
Abstract. The simulation of an automatic light system, which involves the use of ambient light sensors and energy detected from solar panels, can minimize the use of electricity, but nevertheless, provide reliable light sources during different light conditions. Light-Dependent Resistor (LDR) sensors are used in switching on the LEDs when the light intensity drops below 600 lux and switching off the LEDs when the light level increases to above 800-1000 lux, and so they will avoid unnecessary use of energy and ensure that the sensors efficiently respond to the changes in the light intensity. Research also suggests that sensor-controlled lighting and solar panel energy can save up to 65% of the energy used by outdoor lighting systems (and solar LED streetlights can adjust the amount of light they emit (up to 85%) based on the conditions of the environment). The results are favourable for applications of photovoltaic-driven auto lights in real-life scenarios, such as street lighting systems and outdoor lighting, where energy efficiency and visibility at night are critical.
