Ramping Lamp Driver
designed
by David A. Johnson, P.E. |
| This circuit drives any
12v lamp, incandescent or LED type, in a ramping fashion. Each press of the
button toggles the lamp from a fully off mode to a fully on mode. But, instead
of an instantaneous lamp intensity change, the power is slowly ramped
up
and down. |
|
|
With the components shown, the ramping action takes two seconds to complete. By
changing the capacitor C3, you can increase or decrease the ramping time. The
circuit will also operate with supply voltages ranging from 15v to 3v. |
