How to create a layer which only render the given object with the same lighting ?

I create a interior scene by cycles.
I want to create a render layer which only render the given object (ex. a cabinet in living room).
The lighting must as same as the settings in the living room.
Does anyone know how to do it ?
Thanks~

Resovled by myself.
Just my mistake.
I have disabled the sky of the isolated render layer.
