That'll be the switchmode converters. Does the lamp as a whole meet
regulatory EMC requirements...? ;-)

Replace down regulator with linear regulator and add a heat sink. If it
has an up regulator you'd have to change the battery configuration

But you could also try the alu foil / metal mesh idea. You'd have to go
right up to the LED and leave the smallest hole possible there. Relate
any hole size to the wavelength you're trying to shield (bird
transmitter frequency).
