Hmm....getting conflicting reports online whether that genus handles phaelenopsis esque lighting well. Are just certain species thriving in that lighting, or does that genus in general handle 'low' light well?
Look up Dendrochilum on the Internet Orchid Species Photo Encyclopedia:
For each species light recommendations are shown. Sometimes the sun symbol conflicts with the text. The symbol is how people tend to cultivate them. I know the one usually sold as D. magnum takes a lot of sun, but there are other species that seem to do fine with a lot less light.

Angraecums, Aeranthes, Aerangis, Lepanthes, Pleurothallis, Haraella are all good choices. The last three will need a terrarium or jar. You could probably grow Neofinetia falcata in an east window.
There are so many that grow in lower light. Andy's Orchids has a search function where you can select the light and whatever other criteria you want and it will spew out a list of orchids.
