Rohinni’s Lightpaper invites innovative lighting

Rohinni's Twitter statement on what this company is all about is quite simple: We print light. Print light? This Coeur d'Alene, Idaho-based company is introducing its Lightpaper, with a promotional video which is asking the always-engaging "what if" question; in this instance, what if you had the ability to print light? In doing so, it would be "empowering you to create and innovate with light, in ways that were never before possible." Rohinni is introducing the world's thinnest LED lighting, according to the company, with an approach where one can apply it to nearly any surface, in any shape and for any situation.

Popular Science described Lightpaper as "a paper-thin -emitting square. When a charge is sent through it, it glows like a gleaming portal." Last month, in CDAPress (The Coeur d' Alene Press), Nick Smoot, chief marketing officer, said the best way to describe Lightpaper was that it is "a mix of LEDs and ink. Using a proprietary process, that solution is printed on a substrate." He also stressed in that encounter that its application potential was endless, Smoot said they were thinking about printing lamp shades—the lamps would not need light bulbs. "Anywhere there is a light, this could replace that." He also said that eventually people will be able to print their own at home. "You will be able to design and print you own light," he said. "Right now we are printing the light, but we are going to be putting that back in the hands of the people."

Applications in mind? While their answer is "endless markets," limited only by the imagination, they give illustrated examples on their website. The technology could be illuminating logos on products, such as mobile phones, installing lighting on your wall, or a wearable wristband flashing the time and message notifications.

"With Lightpaper it's more of a platform of light that we don't even know how it's going to be used," said Smoot in Fast Company. "All we know is that we're trying to unlock the ability to create light."

Tyler Hayes in Fast Company wrote about their mixing ink and tiny LEDs together and printing them out on a conductive layer. "That object is then sandwiched between two other layers and sealed," he said. "The tiny diodes are about the size of a , and randomly dispersed on the material. When current runs through the diodes, they light up." Smoot did not identify the companies by name, but said a few companies were already working on Lightpaper implementations, according to Hayes. Fast Company said that Lightpaper may be seen "in the wild" around the middle of next year. Before that, they are to work on a second version of Lightpaper, which Hayes said was likely a few months out. The challenge being worked on is to get specific placement of the diodes, to produce completely even light.

Philips, in discussing (LEDs), said that "Once relegated to humble indicator lights in electronic devices," LED lights have advanced, enabling a new category of lighting projected to reach $30 billion by 2025. Philips pointed out that the structure of the LED light is completely different than that of the . "Amazingly, the LED has a simple and strong structure. The beauty of the structure is that it is designed to be versatile, allowing for assembly into many different shapes." Philips added that "Today is an exciting time for those working closely with LED lighting systems, which allow completely new uses of light."

If there ever was a time to invest in a sunglasses industry it's now.

Imagine a room with the whole ceiling lighted without any annoying lamps that collect dust

How much heat does this generate? How much energy input is required to manufacture? Can solar cells be embedded? What is the energy source and how does the charge run through the paper? I'd like to learn more about this technology.

Nth Degree Technologies invented this product.

Relevant patents are posted online, e.g. "Printable composition of a liquid or gel suspension of diodes" by Lowenthal, Ray, et al.

The technology is several things: it is real, it is sufficiently bright to stand up to daylight conditions, it is mass-producible, and it does not heat up to extreme levels.

Lastly, this technology is not the work of Rohinni. They bought some pieces from Nth Degree, and what their business plan is, who knows. They did not invent it, legally cannot sell it without a contract, and it is doubtful they have the the technical knowhow to do so anyway.

In short, Rohinni is taking credit for a product they did not make.

@jcjray: Companies buy patents or pay fees to use patents all the time and we never see any of them giving credit to original inventors. So why is that suddenly a big deal here?

Plus, I have yet to find anywhere where Rohinni is claiming to have invented the process of printing leds, so they aren't exactly stealing credit from anyone. They are just figuring out how to do it on a large scale, which could be a completely different process from the patent you found. From what I can tell, you're just making assumptions without nearly enough information to beck them up.

Can solar cells be embedded?

OK, at first I thought that is stupid.
(Turn on light, light hits solar panel. Panel powers light...Problem? (insert trollface) )

But then it dawned on me that that would actually be very clever for wall-to-wall lighting. As a lot of light goes to waste (i.e. any light you don't see is photons you didn't need to produce in the first place). So recuperating 'unneccesary' photons might be worth it with such large-scale light surfaces.

To add to the questions: Efficiency? Durability? Cost?

@DirtySquirties I am not making assumptions. I have inside information.

As most mediums that need to be lighted are using some other form of lighting, I immediately think of this being used in Clothing, Undercover Police Cars, and of course toys. Its not something that mankind "needs" but it sure would be cool.

Lumens per unit area?

How much surface is needed to get the 1600 lumens that an old fashioned 100W bulb put out?

There's no information in this article beyond its purported existence.

there's probably about a thousand reasons this kind of lighting would only be used in specialty situations OTHER THAN THE REASON IT IS EXPENSIVE TO MAKE AND BUY.

it's performance characteristics are probably inferior for the vast majority of market already covered and competed by conventional incandescent, flourescent, and conventional led.

still cool though.
