Simple High power LED flashlight by Chayapol Posted: 17 Mar 2016 09:29 PM PDT This is simple hight power LED flashlight,we use 24 LEDs super bright for display and 3 AA batteries and resistor for limit current so cheaper. Chayapol buy this LED flashlight but is low light. Thus, he want to builds the new high power LED flashlight with himself. How does it works We use the 24 white super bright LEDs. As circuit diagram in Figure 1. They are connected together in parallel. The each LEDs need to use the voltage about 3.3V – 4V at 20mA current. It makes LEDs uniform brightness, but use all current are 0.4A to 0.6A. Figure 1 Simple High power LED flashlight’s the circuit diagram We used 1 ohms resistor for limit current to save This The post Simple High power LED flashlight by Chayapol appeared first on Electronic projects circuits.
