Stroboscopic effects of lights for nightclubs are realized by bringing into play old white Light Emitting Diodes (LEDs) swapping the ejection lanterns/lamps for superior effectiveness at minimal cost. This control is achievable by instantaneously changing the Light Emitting Diodes on & off at elevated volts for small amount of time span. This speedy control of power from complete shine to complete off aids in creating a stroboscopic outcome which is commonly bring into play in discotheque dance floorboards for improved effects.
8051 family’s programmable micro-controller is fit into placed to give such effect being motivated by a MOSFET for group of Light Emitting Diodes. The microcontroller as per schedule produces ON/OFF commands at lofty rate as a result providing the stroboscopic effect of lights. Since the controller provides merely 5volts drive, it’s not achievable for the MOSFET to be constantly be switched ON at that high voltage. A crossing point transistor is made use of amid the controller productivity and the MOSFET for driving the same.
The power delivery comprises of a 230/12V step down transformer, this transformer steps down the volt to 12V AC. This is transformed to DC by means of a Bridge rectifier. The ripples are detached by means of a capacitive filter and it’s then synchronized to +5Volts by means of a voltage controller 7805 which is necessary for the functioning of the micro-controller and additional gears.
