Direct sunshine is not always a bad thing. And 'bright' ... I don't usually think a space is bright enough until police come to investigate.
The dark green, healthy looking leaves on that Phal indicate to me a plant that is not receiving enough light. The leaves would be at least a shade lighter green with better light. When a plant is just breaking even with its energy reserves you can extend its life indefinitely, with great care and attention paid to what it is potted in, and how it is watered. It will live, but it will never re-bloom like that.
When the lighting is excellent, you don't have to care what it is potted in. Could be Sphag, Coir, Bark, whatever ... pure water! When an orchid is receiving all the light it wants, you can't drown it. Or do anything else to upset it. It becomes superhuman ... superplantian or whatever. Root rot runs away and hides. All there is to do is fertilize.
IME it is impossible to provide adequate light, even to a Phal, and keep it out of 'some' direct sun for an hour or more each day. It won't burn. The sun won't be on it long enough. It needs that SUN though.
I'd better go now or I might mention plant lights <running, ducking>
