This LED searchlight comprises a sealed maintenance-free (SMF) battery, constant voltage battery charger, six high efficiency white LEDs and a LED light level control circuit.White LEDs (D1-D6) gets power supply from the 6V battery through on/off switch S1 (Switch S2 can be used for momentary power switching). Transistor T1 and associated components forms a light level control circuit. With the help of the linear potmeter (P1), user can adjust the intensity of the LED light output. The search light can be recharged by connecting an external ac mains adaptor (12V/1A) to its charger input (J1). Internal battery charger circuit is built around the popular three pin fixed regulator LM7806(IC1). Red LED (D11) works as a charge mode indicator. LED Searchlight Circuit Schematic ?
