This circuit design outlines a simple flashlight system that operates on a 220 V AC supply. The primary component is a triac (T1), specifically the TIC216M, which is utilized for controlling the power delivered to the lamp (L1) rated for a maximum of 500 W. The circuit employs a capacitive charging mechanism to regulate the operation of the flashlight.

The resistor R1, valued at 6.8 kOhm, and capacitor C1 (220 V rated) form an RC charging circuit that allows for the gradual charging of C1 when the circuit is powered. The adjustment of the charging time is facilitated by the potentiometer P2 (100 kOhm), which allows for fine-tuning of the charge time, thereby controlling the duration before the lamp is activated.

Once C1 reaches a predetermined voltage threshold, it triggers the diac D2 (ER 900), which in turn allows current to flow through the triac T1. The activation of T1 subsequently energizes the lamp L1, causing it to illuminate. If the voltage across C1 falls below the required level, the diac will not conduct, allowing the capacitor to recharge without triggering the lamp, thus preventing unwanted flashing.

Additionally, the potentiometer P1 (1 kOhm) is used to adjust the flashing frequency of the lamp. By modifying the resistance, the time constant of the RC circuit is altered, leading to variations in how quickly C1 charges and discharges, effectively controlling the on-off cycling of the lamp.

The diode D1 (1N4004) serves as a protective component, preventing reverse polarity or voltage spikes from damaging the circuit components. This circuit design is suitable for applications where a simple and adjustable flashing flashlight is required, leveraging basic electronic components for functionality.Here a simple design for a flashlight that operates on 220 V.
