The image shows the constant current driver hooked up to a 1w white luxeon led.
Vfwd = 3.0 to 3.4 v, i = 350ma) 1w led driver circuit electronics. High power led lights have lots of applications starting from emergency lights to head lights in some expensive cars. This circuit is designed to drive the 1w leds that are now commonly available.
Our power supplies come in a variety or output voltages and come in many different styles
Mainly applicable to led decorative lighting,. With overload and short circuit protection. In the 5th design let's learn how to illuminate a 1 watt led using a 1.5 aaa cell for a reasonable amount of time.the circuit is obviously based on boost driver technology, other wise driving such a huge load w such minimal source is beyond imagination. However a 1 watt type of led would require a suitable constant voltage power supply for illuminating safely with the specified outputs.
