I want to make constant current LED driver. Input 230v AC. output: 10v DC /300ma constant current

Websearch "constant current LED driver" -- or look at LED drivers here on Instructables -- and add a power supply stage before that which takes the 230VAC and brings it down to a suitable DC voltage for input to the LED driver.

(Modular design. Solve one problem at a time.)
