I am not sure why you need to consider lin/log response...
Controlled current source is all you really need for the purpose.
BTW... for flats a clear blue sky is quite OK.

Well as you may have gathered, I don't know much about it, but I read that normal manufacturer's variations can lead to massive variations in current between different LED's leading to cascading failure as first one blows, then the next, etc so the current needs to be regulated either by current limiting resistors and or by limiting the input current. Have I got that right? I know it depends upon series or parallel, but there will be a mixture of both of contructing an array for lighting purposes, I figure? But what do I know?
