We all know the Christmas garlands made up of cables with colored bulbs that illuminate our Christmas tree. These products made with LED technology are very popular and cheap to obtain. In this video I will explain some of the details of how their basic diagram is designed. of operation and also some cases for which they usually fail. These decorative arrangements consist of braided wiring with low-consumption LED bulbs and a small multifunction plastic box which indicates various modes of operation of the backlights and in some models bringing a small horn with Musical memory. This plastic box with a level of protection IP44 against dust and humidity, it contains an electronic board to which the power supply cables will be soldered and at each output the cables with lights depending on the number of each thyristor, the operating diagram of this circuit is through alternating current, which is rectified continuously by passing through a diode bridge and then through a resistor that lowers its voltage to be rippled by a capacitor that supplies low energy to a small power controller microchip which is connected to a push button with a normally open position and which, when pressed, activates the clock mode of the sequence by sending signals and controlling each thyristor which, when energized, opens and closes the input and output of current to the branch lights like a tap. If, for example, at the output there are two thyristors It means that there will be two parallel strips of LED lights which will join their channels in a series circuit, joining at the end with a last one which has the common cable connected that closes the circuit. The more expensive the garland is, the more channels and components it will bring, varying in some circuits in which there is a high voltage line on the printed board that does not enter through any of the components of the circuit but is synchronized in its direct output towards the last focus of the joint, acting as a common,
