Abstract
The specification discloses a flashing lamp circuit including (1) at least one LED, (2) a dual-BJT astable multivibrator, and (3) a BJT/MOSFET pair that functions as both (a) a switch between the multivibrator and the lamp and (b) a current regulator for the at least one LED.
Claims7
A flashing lamp circuit comprising:
- a light source;
- a multivibrator adapted to be connected to a power supply;
- and
- a switch/regulator circuit operatively connected between the multivibrator and the light source, the switch/regulator circuit acting as an amplifier switch between the multivibrator and the light source, the switch/regulator circuit further acting as a constant current regulator between the multivibrator and the light source.
