Help ID this orchid please

[Kon]

Hello members.

Could someone ID this orchid please.

I bought this orchid without any name tag from, I think, American Plants almost 4 years ago. It's growing and flowering along with my Phals.

All my orchids are next to east window and gets direct sunlight from morning until around 11 am, then I turn on compact fluorescent light that I bought from local nursery.

Thank you

I don't get why pictures are upside down. I apologize. I tried to fix it.
