All incandescent light bulbs use a tungsten filament. When the filament

Over the lifetime of a light bulb, as the filament is heated to near white
hot temperatures to generate light, it starts to slowly break down.

When the filament in a lamp burns out, it sometimes has a bit of a meltdown.
Sometimes pieces of it can short out the metal support contacts feeding
itself. If there is a short, it can cause a fuse to blow, or a circuit
breaker to go to the open mode.

Ah, thanks. That's OK, then. I thought it may have been something to
do with the wiring.
