That will be related to: "direct sunlight lighting" and "indirect sunlight lighting".
But if you refer to artificial light, I guess that you could look at it in the same way. If the artificial light source is powerful enough, then it can also burn or cook an orchid.
One method for avoiding scorching issues is to place the plant in a spot where the path of light is not a direct path - or rather, in a spot where light intensity is not high enough to burn parts of the plant.
For artificial lighting - considerations can be distance between artificial light and the plant, and maybe usage of suitable 'diffuser' assemblies.
