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 Simple LED Torch Circuit Diagram using 4049 IC You have seen many LED torches in the market, mostly use white LEDs as they provide good brightness and light. Today we are making the low cost and highly efficient Simple LED torch light Circuit which allows your battery to live longer, for this we are using a 4049 hex inverter buffer IC. Novel White LED Torch Circuit Diagram Learning Electronics Novel White LED Torch Although this design is reproduced directly from the manufacturer’s datasheets, its use in this application is rather novel. 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. LED Based Rechargeable Torch | Detailed Circuit Available Fig. 1: Circuit diagram of the LED based rechargeable torch Fig. 1 shows the circuit of the rechargeable white LED based torch. The reactive impedance of capacitors C1 through C3 (rated for 250V AC) limits the current to the charger circuit. LED Torch Circuit Diagrams 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 Flashlight Circuit Diagram White Led Torch Circuit Diagram – Wiring Diagram 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. High power LED flashlight circuit with 1.5V AA battery This high power LED flashlight circuit look like a torch by use on 1.5V battery only so it can be used. Since small so Easy to carry in various places. And also very bright as well. Since small so Easy to carry in various places. 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.

White Led Torch Circuit Diagram Luxury Led Panel Light Circuit Diagram Diy Enthusiasts Wiring Diagrams . White Led Torch Circuit Diagram Luxury Led Panel Light Circuit Diagram Diy Enthusiasts Wiring Diagrams 30 LED Projects Talking Electronics The LED in the first diagram does not illuminate because a red LED requires 1.7v and the cell only supplies 1.5v. The LED in the second diagram is damaged because it requires 1.7v and the two cells supply 3v. A resistor is needed to limit the current to about 25mA and also the voltage to 1.7v, as shown in the third diagram. The fourth diagram is the circuit for layout #3 showing the symbol for ...
