Lights keep tripping out

My lights keep blowing the trip circuit ?????

no lights are on the circuit will pop after 10Mins or upto 10Hrs.

Lights switched circuit will pop after 1min upto 3hrs.

regardless of what lights are on or switched on.

sometimes when it pops the circuit it takes out the power circuit.

i have replaced all blown bulbs & exchanged so old ones with new.

no bearing of the time of day when the lights are affected.

the outside lights which are on PIR detectors are on the same circuit.

how do i find the problem no bulbs had been replaced prior to the problem..

It sounds like there is too much on the circuit. Some clarification is also needed, are you saying the breaker trips or is there a GFI involved also?

Mod note: The poster is in the UK.
Courtesy Wikipedia:
In the United States and Canada, a residual current device is most commonly known as a ground fault circuit interrupter (GFCI), ground fault interrupter (GFI) or an appliance leakage current interrupter (ALCI). In Australia they are sometimes known as "safety switches" or simply "RCD" and in the United Kingdom, along with circuit breakers, they can be referred to as "trips" or "trip switches".

The RCD trip throws on the Light circuit in the fuse box, but can blow the main circuit breaker on the main fuse.

if there is no lights switched on can the circuit be overloaded.
