Firstly, Knowing that the foremost makers of DLP and liquid crystal display projectors claim their units are appropriate to be used in daylight, it might be a selling gimmick to draw additional sales. several best projectors under $400 claim to be suitable for out of doors daylight. however are they really suitable?
the truth is that any projector can be used outdoors as long as there’s enough light-weight from different sources reminiscent of a window or sky lighting or a high gain screen to mirror more close light onto the projector. Are best projectors for Bright room suitable for outdoor daylight?
The additional powerful projectors that are meant for outdoors usually have a way longer projection distance. It permits them to be placed additional far from the screen so the close light-weight are going to be mirrored simply onto the projector while not it having to bounce off of an outsized white surface.
However, if you’ve got atiny low moveable “short throw” projector meant for indoor use, then it’ll not work outdoors unless you’ll place it on high of a colossal white sheet to mirror the image in your eyes.
“Short throw” means it’s a short, tiny projection distance. A typical “short throw” projector could have a three foot to 5-foot projection distance. to convey you a concept of however massive this is, a typical pc monitor has concerning two feet or less from the eyes to the screen!
“Front or Rear Projection”? – Which is Better?
the solution is that they each have their blessings and disadvantages. There are trade-offs with both forms of projectors.
I like “rear projection” as a result of it permits a additional miniature, lighter-weight projector. It are often utilized in any lighting condition inside or outdoors and is typically cheaper than front projection. In addition, you’ll place the screen virtually anyplace on the wall or ceiling and still relish an excellent, large, distortion-free image.
I actually have used each rear and front projection with nice results! Deciding to use one over the opposite depends on your preference and application of its use.
How many lumens do you need to project in daylight?
It depends on however way you’re projecting, the close light-weight level, and whether or not you’ve got a screen.
A large screen would require additional lumens than a little one. Remember: “If you can’t see it in your house throughout the day with all of the light-weights on, then you won’t be ready to see it within the daylight either with or while not a screen.”
If you’re employing a small screen, then let’s say 4′ x 6′, you’ll use the subsequent chart as a start line for lumens required. you’ll invariably bump it up to visualize if more is better. If you discover legion light touching your screen, you will ought to back it off. you would like the close light-weight returning into your projector to be mirrored onto Associate in Nursing angle kind of like a screen size of a minimum of 4′ x 6′.
Example: – Use a camera and place it ahead of a wall, with its flash unit on, and take an image of however bright the wall is within the daytime.
Now, mistreatment your camera, take a picture of the wall once you set up your screen size so retake it with the projector on at concerning 150″ to 200″ – it’ll tell you how much close light-weight is touching your screen.
If you don’t have a digital camera, get a “brightness” level meter and place it on the wall and your screen.
If you’ve got a viewport, close up everything within the area and place the brightness meter close to the seating position ahead of your projector. If you don’t have this option, put it wherever people’s eyes would be throughout everyday use.
Another manner is to show at the projector and examine the brightness for your eye of the display. Then check out the mild supply this is growing that ambient mild (the window) and spot how brilliant it appears – You can commonly inform if there is lots of distinction among them or now no longer. If you operate a the front projected system, degree the ambient mild degree in which the projector can be placed, now no longer in which you’re sitting.
The above instance offers a difficult concept of what number of lumens you can want to undertaking in daylight. If you’ve got got a huge display (8′ extensive or more) and plan to location your projector a ways farfar from it – In this case, you can want to bump up the lumens even more.
Now, in case you are in a room with masses of ambient mild and plan to have a massive display (10′ extensive plus) or need to location your projector proper towards the display, you’ll want fewer lumens than what we simply mentioned above. Remember: “The nearer which you location the projector for your display or use a bigger display, then you’ll want fewer lumens than in addition away.”
