To save space you can use one 3.3 ohm resistor instead of three 10 ohm resistors in parallel. Also you could rather use a LM2941 instead of LM317. It is a low dropout regulator so you won't need such a high voltage to use the driver, just search the web to find led drivers that uses one. Here is one link: Application Note - Driving high power and high brightness LEDs Application Note 5310 (838 KB)
