Cliquez pour agrandir High-power constant-current source for DC voltage up to 24 V max. in an extremely compact design. Several 3 watt (i.e. Luxeon star) with different colors can be switched in row. No additional series resistance is required. The circuit supplies the High-power LEDs with the necessary voltage and a constant current of 1500mA and reliably protects the LEDs against voltage peaks.
Some examples to point out the variety of connection possibilities:
At an input voltage of 12 V you can attach the following LEDs:
3 red, amber or red/orange 3 watt LEDs
At an input voltage of 24 V you can attach the following LEDs:
7 red, amber or red/orange 3 watt LEDs
Input
DC voltage
Startup: ca. 5,1 Volts (for one red 3 watts LED) reverse polarity protection Startup: ca. 4,7 Volts (for one red 3-watts LED) without reverse polarity protectionbr up to 24 V max.
Output
1500 mA constant-current
Automatic voltage regulation
The possible amount of LEDs depends on color and input voltage

voila pour ceux que ca interesse,le modele de mon driver
et pour la suite je pense monter le tout dans un tube inox avec watercooling !!! car à 1500mA ça va chauffer !!
pas de contre indications pour ce montage ???
