I would start by looking at the spec for the part as some high power LEDs have a tight requirement on their heatsink requirements.
The IPC spec comes after the component spec if the component spec demands more area of connection (lack of voids) than IPC.

Subject: [TN] LED Ilumination Voids
Hi to all,
We have IPC (e.g.:7095) for BGA and voids percent not allowed. But for LED Ilumination, is there rule (IPC documentation)? We can use the same criteria for BGA, in the void case?
We are soldering LED and when we inspected with X-Ray, the quantity voids in the soldering is elevated so we didn´t know define the ok percent.
Thank you
Juliano Ribeiro
