ABSTRACT:
Stroboscopic lighting impacts for discotheques are accomplished by utilizing conventional white LEDs replacing the discharge lights for higher efficiency at low cost. This control is possible by instantly switching the LEDs on and off at higher voltages for less time period.
This quick control of intensity from full glow to full off helps in developing a stroboscopic effect which is by and generally utilized as a part of disco dance floors for better impacts.
A programmable microcontroller from 8051 family is engaged in to give such impact being driven by a MOSFET for bunch of LEDs. The controller as according to the program creates ON/OFF commands the at high rate along these lines giving the impact of stroboscopic lights.
As the controller gives just 5v drive, it isn’t feasible for the MOSFET to be dependably exchanged ON at that voltage. An interfacing transistor is utilized between the controller yield and the MOSFET for driving the same.
The power supply comprises of a stage down transformer 230/12V, which project down the voltage to 12V AC. This is converted to DC utilizing a Bridge Rectifier. The ripples are removed utilizing a capacitive filter and it is then directed to +5V utilizing a voltage controller 7805 which is required for the task of the microcontroller and different components.
