La fuente de luz LED actual funciona como sigue. Cuando la red de suministro de potencia se aplica a la entrada del convertidor reductor de tensión A, los condensadores 5 empiezan a cargarse; cuando esto se produce, el régimen de carga está limitado por las resistencias 20 de limitación de corriente 1. El supresor de tensión 2 limita los picos de los saltos de tensión de la red por un valor aceptable (generalmente, se supone que es igual a 1,2-1,5 del valor nominal de la tensión de red). La tensión reducida del convertidor reductor A se aplica a la entrada del puente de diodos rectificadores 7, y se aplica una corriente continua desde la salida del puente de diodos rectificadores a través de la resistencia térmica 8 a los 25 LED 11. Como en condiciones de baja temperatura la resistencia de la resistencia térmica 8 es igual a cientos de ohmios y, mientras se calienta, cae a sólo algunos ohmios, la tensión de alimentación de los LED 11 aumenta gradualmente, parpadean, y suavemente se iluminan, iluminando un área circundante. Las resistencias de descarga 3, 4 y 6 proporcionan la eliminación de la carga acumulada en los condensadores de los circuitos, The current LED light source works as follows. When the power supply network is applied to the input of the voltage reducing converter A, the capacitors 5 begin to charge; when this occurs, the charging regime is limited by the current limiting resistors 20 1. The voltage suppressor 2 limits the peaks of the network voltage drops by an acceptable value (generally, it is assumed to be equal to 1.2-1.5 of the nominal value of the mains voltage). The reduced voltage of the reduction converter A is applied to the input of the rectifier diode bridge 7, and a direct current is applied from the output of the rectifier diode bridge through the thermal resistance 8 to the 25 LEDs 11. As in conditions of low temperature the resistance of the thermal resistance 8 is equal to hundreds of ohms and, while heating, falls to only a few ohms, the supply voltage of the LEDs 11 gradually increases, blinks, and smoothly illuminate, illuminating a surrounding area. The discharge resistors 3, 4 and 6 provide the elimination of the accumulated charge on the circuit capacitors,

30 después del apagado de la fuente de luz LED. El condensador 9 proporciona el aplanado de las ondas de corriente rectificada, y la resistencia de absorción 10 logra una descarga efectiva del condensador 9 después de que el dispositivo se apague, lo que proporciona una supresión abrupta de los LED. 30 after switching off the LED light source. The capacitor 9 provides the flattening of the rectified current waves, and the absorption resistance 10 achieves an effective discharge of the capacitor 9 after the device is turned off, which provides an abrupt suppression of the LEDs.
