LED TORCH CIRCUITS Talking Electronics When we first decided to produce a LED torch project, we wanted to fit the circuit into a 2 cell torch but a white LED requires about 3.4v to operate, and two cells produce only 3v. So we had to think of a number of ways around the problem. That's why we have produced a number of circuits. Simple LED Torch Circuit Diagram using 4049 IC Circuit Diagram Need of IC 4049 for LED torch Circuit: As we know it is impossible to glow three white LEDs in series with full brightness using 5v 20mA directly, if we connect the LEDs in parallel the value of current will increase and the battery will drain fastly. Simple Hi Efficiency LED Torch Circuit | Homemade Circuit ... A simple LED torch circuit that would light up 3 white LEDs from a 6 volt supply and would make your battery last forever is described here. A useful voltage doubler circuit is incorporated here to make a highly efficient circuit using just a handful of components. 1.5V LED torch circuit or flashlight ElecCircuit SEE! The 1.5V LED torch circuit or simple flashlight circuit. Which also use single 1 AA 1.5V battery. It uses a few parts. Such as we use 1 transistor and all other parts of 5 pcs only. Another advantage of it is that it saves a lot of battery power. and Small size. You can make it! Home Made Bright White LED Torch Flashlight Circuit ... I have been using this circuit for a long time, so i thought posting schematic of this torch flash light might be useful for some DIY people like me as it is a very useful circuit to build. this torch light circuit can provide good battery backup. the circuit uses 3 high bright white LEDs to provide sufficient light in the. darkness. Two Cell LED Torch Schematic Circuit Diagram Two Cell LED Torch Schematic Circuit Diagram. on: June 22, 2019 In: Battery Circuit Diagrams, LCD LED Display No ments. Print Email. It sometimes comes as a bit of a shock the first time you need to replace the batteries in an LED torch and find that they are not the usual supermarket grade alkaline batteries but in fact expensive Lithium ... LED Circuits and Projects Simple circuit with circuit ... A preset and potentiometer is also needed for the circuit. 4. LED Torch Using MAX660. A MX 66o CMOS type voltage converter IC is used to make this LED torch circuit. The IC has the capacity to drive 3 bright white LED’s. This is a simple LED torch circuit based on IC MAX660 from MAXIM semiconductors.

So we had to think of a number of ways around the problem. That's why we have produced a number of circuits. LED Torch circuit diagrams, schematics, electronic projects The LED Torch is based on a 7555 timer running in astable mode (do not use an ordinary 555). A white LED (Maplin order code NR73) produces 400 mcd light output, which, when focussed, can illuminate objects at 30 metres. Try Conrad Electronic for what appears to be a stronger white LED (order code 15 37 45 11). LED torch using MAX660 Electronic Circuits and Diagrams ... Description. This is a simple LED torch circuit based on IC MAX660 from MAXIM semiconductors. The MAX 660 is a CMOS type monolithic type voltage converter IC. The IC can easily drive three extra bright white LEDs.The LEDs are connected in parallel to the output pin 8 of the IC. The circuit has good battery life. The switch S1 can be a push to ON switch.
