Lounge Lights and What to do With Black Wires?

[Susiesuse]

Hi. Just bought a light for the lounge. Normally these things are ok but I just wanted to double check. I have 1 blue, 1 earth and 3 black wires coming from the ceiling. One of the blacks has a red collar so this is the live switch presumably. My question is what do I do with the other 2 black wires? The old light had them wired into the neutral. The new light has brown, blue and earth so that’s simple but then provides an extra circuit block with 2 spaces for the loop. Do I wire the black wires into this block effectively connecting them? Electrician on holiday currently. I have wired them and they work. Not tripped. New fuse box. But assume not tripping and working not always equals correct. Thanks in advance.

A picture would really help. Blue wire from the ceiling?

Is there any chance there are two switches & two lights in the same area ?
Photo would help.

Hi. Yes blue coming from ceiling. Here is the old wiring and yes there are other lights. 2 main ones with separate switches and 2 wall lights that run off the same switch but now one of the wall lights isn’t working. They are just blue, brown, earth.
