Lighting project help please

[markymark2406]

ok here goes, I have on the outside of my house a front wall light, x2 small lighting bollards at the entrance of my drive way and x2 down slots in my facias.
There are all controlled by a sangamo solar time clock in my loft.
The lamps in the light fittings are all dimmable LED’s but what I want to do is design a system when the lights go on when it’s dusk and then all dim down to about 25% at say 10:30pm then off at midnight.
I know I could possibly use a domestic dimmer switch which goes into circuit at that 10:30pm time and possibly use some kind of relay but unsure how.
Any help would greatly be appreciated Thank you .

Thank you for that Bernard, I was looking to use a relay of
Some sort my thinking is to have 230v going into sangamo time clock then into a relay with timer then out of one way of the relay to lights then at 10pm the relay changed state making the supply go through a domestic dimmer then out out to lights ?
