Hi Doreen,
So you have identified the cables that are feeding supply via the switch.
The rest is easy! bd3cc had previously given you info regarding this but I'll go over it again for you.
Isolate circuit ensuring the circuit is not live and here we go:
The 3 browns are as follows
One brown is feeding live supply to fitting known as incoming supply, that will either come straight from consumer unit or previous light on circuit.
one brown is supplying feed to next light in circuit known as out-going supply, the other is going to your switch, supplying a live to the switch.
All these should be terminated together (with nothing else) if it's ceiling rose fitting these cables can be terminated in to the terminals marked loop, the three terminals in the middle or if it is not a ceiling rose fitting a plastic terminal block should be used but remember these cables need to be in contact with each other to work when using terminal blocks.
The Three blues
2 are neutrals and are incoming and out-going neutrals, these need to be connected to the blue flex side of light this is your neutral terminal on your rose or fitting, agian these need be in contact with each other to work.
The spare blue is not a neutral, but a switch live this, this should be marked up with brown sleeve, if not once indentified do it as it will help next time the fitting is replaced.
This cable is coming from your switch offering power to the lamp when switch is closed, this should be terminated on the live side of ceiling rose or fitting this will connect to the brown flex cable of light not to confused with three browns we connected earlier.
All earth cables to earth terminals on rose/fitting.
and let there be light.
Hope this info was helpful and easy to understand.
