PROJECT DESCRIPTION

This project is designed to provide a flashing ambulance lamp simulating a beacon light which is generally used in ambulances, emergency vehicle etc.

Warning lighting features in ambulance roof top is generally used to clear the right of way for emergency vehicles and also to warn approaching motorists to wait and allow it to pass smoothly.

It is also used in middle of the sea to warn ships about the hidden rocks. A programmable microcontroller from the 8051 family is engaged to provide flashing light at periodical intervals as per the standard practice followed for different type of emergency needs.

 A low-voltage lamp of 12V is driven by a power MOSFET in PWM mode which is derived from a microcontroller. The duty cycle of the PWM has to be changed depending on the type of application.

As the controller gives only 5v drive, it is not possible for the MOSFET to be reliably switched ON at that voltage. An interfacing transistor is used between the controller output and the MOSFET for driving the same effectively.

Furthermore, the project can be enhanced by using a high-power 230V lamp in combination with solid state switching for better visibility.
