Join Paul F. Aubin for an in-depth discussion in this video Inserting artificial lights, part of Revit: Rendering.
- Revit has two kinds of lighting that we can use to light our scenes. We of course have the sun that we can use if we're doing day lighting, we've got the sun turned on right now in this view that we're seeing here streaming in through the windows with the shadows turned on. And we can also do artificial lighting. Now the unique thing about Revit's artificial lighting is that you don't actually go to a separate lighting object that's somehow distinct and separate from the fixture itself. In other words, when you bring in a lighting fixture family in Revit, that family contains the lighting information.
So a single family does both jobs. It actually displays the fixture and its housing and whatever the actual physical object looks like, and it also casts light. So let's go ahead and add some lights to this very simple scene that I have here. So I'm going to start in a ceiling plan, so I'll go to my level one ceiling plan view. Let me just zoom in slightly here, and you can see I have this ceiling grid in the middle of the space that's kind of floating in there, so I'm gonna add some recessed lights in that portion of the ceiling, I'm gonna add some sconces on the walls, and then I'll even maybe do a freestanding desk lamp on one of those objects in the middle of the scene.
Now these are just components, so if I go to the component tool and I open up the type selector and scroll through the list, I don't currently have the lights I need. There is the sconce light, it's already here, but as far as any of the other lights that I need they're not currently loaded in this file. So I'll simply go to Load Family and go to my Lighting folder, Architectural, Internal Lighting, and then choose the fixtures I want. Now if I select one over at the top here, and kinda look in the preview, you'll see that most of these have this yellow object in them.
That yellow object is the actual light source, so that represents the light that's being cast from that family. But notice in some cases like this one, this is a floor lamp, it's got a stand and the pole that's holding it up, and then the light source up at the top. So you can see there's several different light fixtures for you to choose from. Well I'm gonna scroll down here and select the Troffer Light - 2x4 Parabolic. And holding down my control key, I'll also select a Desk Lamp, this Table Lamp right here with an arm extension.
So I'll select both of those and click open, and you'll see that the Troffer Light is added to my cursor, and I can begin placing it in. It kind of starts to snap to the grid and you could do that, but I always like to set it off to the side and use my align tool just to make sure that it's actually snapping correctly. So I'll go ahead and place the first one, go to modify, and then click align. And I'll align with this grid, the edge of the light, and this grid and the edge of the light.
Then I'll select it, go to copy, turn on multiple copy, pick a good convenient base point and place several copies. I'll cancel out of there, select all four of them, copy again, multiple still turned on, and place some more. So that takes care of the recessed lighting. Now I'm not seeing the sconce lights here in the ceiling plan, so if I go back to my level one floor plan, you'll see that there already are some sconce lights over here on the right-hand side.
They were just too low to be picked up by the ceiling plan. So I'm gonna select one of those, click create similar, and then place one at the middle of each of these walls between the windows. And then cancel outta there. And then finally, I've got this little table in the middle, so I'll go back to component, open up the list, find that Table Lamp, and maybe I'll choose the 100 watt, 120 volt version and I'll kinda click right about the middle of the table to place it.
Now it'll disappear, because even though I clicked near the table it actually went to the floor. But I can just kind of make a window selection here to select it, it's actually right inside that little cube there, and then over here use the offset feature. Put in the height of the box, that box is at about three feet, and now it should pop it right up to the top of that box. Now I'll deselect it, I'll go back to my interior view, and so you can see the result of all those light fixtures I've placed. So placing artificial light fixtures in the scene is no different than placing any other components in Revit, but the unique feature is that these simple components, that you're bringing in, these lighting fixture families, actually have the light source embedded in them.
So in the next few movies when we actually start using those light sources, you'll see that they cast light into the scene for us.
