Emissive material with already baked lighting. Not work.

I use baked lighting in my scene, but i want to use some dynamical emissive after baking.
When i add emissive sphere to scene, it only add some specularity, but no desirable halo around it.

How to force halo in emissive, like in emissive material?
(I think i don’t need shadows from emissive. Only halo.)
