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. How to build LED Torch circuit diagram How to build LED Torch ... Circuit diagram. A common problem with small torches is the short life span both of the batteries and the bulb. The average incandescent torch, for instance, consumes around 2 Watts. The LED Torch in Fig. 1 consumes just 24 mW, giving it more than 80 times longer service from 4 AA alkaline batteries (that is, up to ... 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! DIY Torch Light : 9 Steps instructables DIY Torch Light : This is a very simple led torch light that uses the series connection of a led, a switch, a resistor and a 9 volt battery. It is very handy to use when there is no light. To make the torch brighter the number of LEDs can be added. 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 – Circuit Wiring Diagrams 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. How to Make a LED Flashlight Circuit | Homemade Circuit ... The LED flashlight circuit explained here is very simple, and it simply requires to follow the instructions as given for making it successfully. The proposed circuit utilizes just a single high bright white LED, three 1.5 volt button cells and a switch. LED Torch – Circuit Wiring 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). LEDs for Beginners: 9 Steps (with Pictures) LEDs for Beginners: This instructable shows how to wire up one or more LEDs in a in a basic and clear way. Never done any work before with LEDs and don't know how to use them? Its ok, neither have I.***If you have wired up LEDs before, this explanation might seem o... High power LED flashlight circuit with 1.5V AA battery Figure 1 Circuit diagram of High power 6 LED Flashlight for 1.5V AA battery.. As Figure 1 is Circuit diagram of this project. By operation of the circuit is determined by Coil and C2. Which will serve as the production cycle frequency. The LC Frequency circuit with capacitors and capacitor alternately, cause frequency. LED Based Rechargeable Torch | Detailed Circuit Available Here’s a white LED based rechargeable torch that consumes just 300 mW and has 60 per cent longer service life than an average incandescent torch. LED based rechargeable torch circuit Fig. 1: Circuit diagram of the LED based rechargeable torch. Fig. 1 shows the circuit of the rechargeable white LED based torch. 30 LED Projects talkingelectronics 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 the LED, resistor and battery and how the three are connected. The LED in the fifth diagram does not work because it is around the wrong way.
