Tracks vs signal planes for high power LED PCB

Hello,

I am designing a PCB for high power LEDs. I have been looking at some commercial modules and have seen that many of them use signal planes instead of tracks for current transmission. is this recommendable instead of using tracks? In the case where the LEDs have an additional thermal pad in addition to the anode and cathode, will it also be advisable to use signal planes for current transmission, or just use the flat for the thermal pad?

Example of signal plane based PCB attached.

Thanks in advance!

Thanks in advance!
Take a look at "LED PCB" fabrication. Some of these use aluminum (metal-core PCB) to help dissipate heat much quicker.
