Super bright LED night light


Posted on Feb 5, 2014

Here is the circuit diagram of a super bright LED night lamp that can be operated from the mains supply. Bridge D1 is used to rectify the AC mains voltage. The capacitor C1 and resistor R1 forms the current limiting circuit. 10 ultra bright white LEDs are wired in series to produce the required light. The n-channel FET Q1(ZVN 2106) is used to auto

matically switch the lamp OFF at full light. The photo cell resistance is set to be 100K at full brightness. Anything less than this 100K will instantly switch the LEDs OFF. Zener diode D2 is used to limit the peak voltage across C1 during the switching of LEDs.
