Infra Red (IR) LED Flood Light Circuit Diagram
The adjoining design shows a simple IR flood light circuit diagram for IR illumination applications.
The 4049 section is the basic voltage doubler circuit which effectively boosts the 9 V supply to a level of around 15 V which further becomes the suypply voltage for the next 555 pulse modulator section.
The voltage is suitably pulsed as per the settings of P1 and P2 for driving the associated IR LEDs.
The main feature of this circuit is that it utilizes just a single PP3 9 volt battery and yet is able to provide lights (IR) at dazzling levels.
