Abstract

Sistema de iluminación capaz de regular la impedancia y la conexión a la alimentación de una matriz (1) de LEDs (2) en ramas paralelas idénticas de varios diodos en serie de manera directa a un sistema de baterías (3), adaptándose a los parámetros eléctricos y ambientales en los que funciona. El sistema incluye un microcontrolador (4) que está conectado a un sensor de temperatura (7) incrustado en la matriz (1) y a una señal analógica (6) que mide la carga en los bornes de la batería (3). El microcontrolador (4) se conecta también a un transistor (5) a través del cual mediante una señal PWM puede conmutar la alimentación de los LEDs (2) para controlar su funcionamiento, como en el caso de recibir una lectura del sensor de temperatura (7) mayor que un valor de trabajo nominal máximo definido. Así mismo, controla un segundo sistema de regulación que comprende un segundo transistor y una resistencia en serie conectados en paralelo con uno de los LED (2) de cada rama de la matriz (1), que se activa cuando la tensión en los bornes de la batería es menor que un determinado valor fijado por el diseño de la matriz (1) y la elección del modelo de LED (2).Lighting system capable of regulating the impedance and the power supply of a matrix (1) of LEDs (2) in identical parallel branches of several diodes in series directly to a battery system (3), adapting to the parameters electrical and environmental in which it works. The system includes a microcontroller (4) that is connected to a temperature sensor (7) embedded in the matrix (1) and an analog signal (6) that measures the charge on the battery terminals (3). The microcontroller (4) is also connected to a transistor (5) through which by means of a PWM signal you can switch the power supply of the LEDs (2) to control its operation, as in the case of receiving a temperature sensor reading ( 7) greater than a defined maximum nominal work value. It also controls a second regulation system comprising a second transistor and a series resistor connected in parallel with one of the LEDs (2) of each branch of the matrix (1), which is activated when the voltage at the terminals of The battery is less than a certain value set by the design of the matrix (1) and the choice of the LED model (2).
