Ceiling fan light stays on. I think it takes a remote?

So, we just bought a house. When we did our walk through and looked at it, I think i remember them using a remote to turn the light on and off, but I'm not 100% sure on that. There is a switch on the wall, but it does nothing. When I unscrew the globe, it's not a bulb, but a round LED panel with a bunch of LED bulbs. No switches on the fan anywhere. We've looked all over. Anyone know how to turn the light off? Or if it is a remote, is there a replacement i can buy? I didn't see a brand name anywhere.
