PERFECCIONAMIENTO EN LOS CIRCUITOS DE ILUMINACION CON DIODOS ELECTROLUMINISCENTES, ESPECIALMENTE PARA VEHICULOS AUTOMOVILES, LUZ DE SEÑALIZACION Y TABLERO DE CONTROL QUE LA INCORPORA.

摘要

The illumination circuit includes three parallel branches of LEDs forming "i" lines and "j" columns. The network is connected with each branch connected in series and individual LEDs paralleled up, forming a total of "ij" LEDs. Some of the branches have resistors in parallel (22,23). Each LED circuit has a series resistance and zener diode (Ri) placed in series with it.
