3 Reasons to Choose LED versus Projection
LED versus projection is a question we deal with an awful lot. In order to answer the question of which is better, we need to take a look at the two technologies in multiscreen environments.
LED Mapping is similar to projection mapping, but has some obvious, and maybe not so obvious differences. LED Is becoming the standard for signage, video monitors, and even replacing projection systems around the world. Why the shift from projection or more “traditional” options? There’s a number of reasons, but I’d like to dive into the top three.
One of the consistent and overarching issues with projection is brightness…there’s almost never enough. Whether you’re in a theatre fighting stage lights, projecting a movie outside, or using projection with full house lights on during your Sunday services, it always seems to require some level of compromise in regards to brightness. With LED, you can break through the light with light. How? Let’s dive in real quick to specifics.
With projection technology you are going to be dealing with reflected light. Regardless of front or rear projection, the light will be reflected off of the screen surface. Measured in LUX, the reflected light in projection technology is in the total amount of light present. In contrast, LED is measured using NIT, or direct light. Essentially you have a light source, not simply a reflection of light. There’s a lot of technical specs, but what it comes down to is this: 1 measure of NIT equals 3.426 units of LUX.
All that to say, LED is a direct light source technology which makes for a much brighter output of light.
Unlike projection, you can map LED with much more versatility. Simply by arranging panels in a certain manner, you have the ability to create shapes, walls, and more. This technology is modular in nature in that most manufacturers arrange the LED in squares of 1-2 feet across that you simply connect together.
Configurations are almost endless with LED. Being a modular, panel setup, allows you to be creative in any environment.
Curtains – LED Environmental Mapping
LED curtains are just what they sound like, black curtain with LED’s interwoven. Rated between 3.9mm and 100mm, you’ll be able to create an immersive environment, similar to environmental projection with more control and flexibility.
LED brings in a great amount of flexibility as it doesn’t require additional components or gear such as lensing, focus control, or zoom control. Put it where you need it and you’re just about ready to go. What’s more, with LED you don’t have to worry about shadows, projecting on people, or masking.
You may think that LED is out of the range of possibility for you. Depending on your total budget, you might be right. However, when you consider more than just the initial up front cost, you really need to look at LED as a viable option (if it works in your environment.) Overall light output will degrade over time with projection. With LED, you may lose a pixel here or there, but those can be replaced within a small panel. With projection, if you have a dead spot, lines, or blow a lamp you lose your whole image, while LED will only affect the one pixel.
There are pros and cons to LED and Projection technologies. You need to consider your space, budget, design, and more to determine what’s best for you. If you have any questions or need help brainstorming ideas, let us know![PHOTOS/DIAGRAMS – found in The Wide Guide.]
