Please help me make an awesome setup!

I have about 8 orchids and I'm unable to make them thrive during the winter. I would love some input from the pro's! I'm in NE Wisconsin and have a room that I believe was built for orchids. It's in the NE corner of the house. It has a heat vent, but that room gets freezing in the winter. I'd like to convert and old entry/living room planter into an awesome set up. There's an outlet in the ceiling and I'm willing to invest some money into this project. I have an electrician friend who can do whatever I need. I really like the purple LEDS. I am certain they will need light. I have very few windows to use in the rest of the house and they are professionally tinted, so I think they filter the light coming in. I cannot put anything in the planter because of my little ones. I was imagining I could build a few shelves or even hang the plants on the vertical slats. Could a few of you kindly give me a few suggestions?
