Simplest Strobe Light Circuit

Last Updated on November 27, 2024 by Admin 3 Comments

A very simple strobe light circuit can be built using a single transistor and a high bright white LED, in conjunction with a flickering LED.

As may be seen in the diagram, a simple single transistor driver is used for illuminating the strobe LED lamp, which is controlled by a self oscillating flickering LED connected at the base of the driver transistor.

These flickering LEDs are nowadays are quite common everywhere, and can e easily procured from any electronic spare part shop. These LEDs are featured with an internal oscillator and multi-color LED chip within a single embedded package.

 

It just requires a 3 supply and that's enough for this LED to start randomly flashing with multiple colors. Although these LEDs are individually used for decoration purpose, in our simplest strobe light circuit it is applied as an oscillator for the driver transistor, which it effectively implements.

As soon as the circuit is powered with 6V, the flickering LED starts randomly flickering at causing the base potential of the transistor to alternately and rapidly trigger ON/OFF at the same rate the flickering LED oscillations.

 

This in turn causes the collector high bright LED to flash rapidly and intermittently producing an eye blinding strobe light effect.

This little simple strobe light circuit could be installed in caps, shirts buttons or anywhere you desire for generating a eye catching strobe effect in crowds or festivals occasions.

About Admin

Hey friends, Thanks a bunch for stopping by this site! I am an engineer with a Bachelor of Engineering in Electronics and Telecommunication. One of my passions is gathering information from all sorts of electronics books and tutorials. I then take that information and compile it into a language that is super easy to understand. My goal is to make those complex electronics circuit concepts and technical terms much more accessible for all the new and budding electronics engineers out there. I can also design customized circuit diagrams as required by the users.
If you have any questions related to this field, please do not hesitate to drop a comment! I am always here and ready to help you out with any queries you might have. I cannot wait to hear from you!

    I tried this assembly in Proteus (ISIS) by placing a switch on led1 to simulate a flashing led but it does not work. Do you have a solution?

      Don’t try simulating, try it practically with real components, it will surely work
