This has the potential to be a real shift in the way that lighting is used. I am curious if the lighting designer community is aware of this and what they think of it. Uniform lighting from a surface would do very strange things to shadows, for example. This is the kind of change may take some time for people to get comfortable with. On the other hand, put it in the hands of a designer that can do interesting things with it and it could take off very quickly. Larry M.

Interesting article on what new innovative startups can do to the industry. The reality is that when the startup industry is healthy, the nation is better off. However, this industry does not have any standard benchmark. We need to develop one so that we can handle the health and environmental issues associated with LED. This is important as new innovations are expected to flood the market as we transition from lab to market.

The LightCell products extracts a uniform light from a panel that is 50x50 mm. Building large surfaces is done in a modular approach, placing several LightCells together to create a large panel of any size. The LightCell is designed to maintain the uniformity between all LightCells in the fixture and create a large and uniform lighting surface. Our unique on-board sensing mechanism will assure that this uniformity will be preserved through changes in temperature and over time. The electrical interface is indeed simple and can be operated by standard drivers available in the market.

Agree with the health concern that LED industry has brought along. We need some more medical advice especially it is not difficult for LED/semiconductor to emit "unseen" radiation. A well controlled LED manufacturing standard should also imposed so that no harmful emission can be found. Anyway, LED is still a very promising technology that people can enjoy the benefit of better energy efficient at the end of the day.

Yes, I do agree with “hm” over there on the safety concerns. While I appreciate the Oree Inc. for bringing out to marketplace an efficient technology and for being a remarkable new venture that it is, I can not under-emphasize the importance the requirement of some kind of standardization framework for LED-based lighting. LED-based light products is a hot market, and players emerge with interesting innovations in an economic sense. However, on an eye-safety standpoint, all these innovators might not measure up adequately. For an example, most LED-based light sources used in advertising industry, seems to have little care for the safety of the eyes of the by-standers, while they aim for visibility and clarity at audiences at longer range. Further, even some of the domestic light products aimed to produce ‘warm-white’ seems to have poor control of the emitting angle of the light. These are some of the issues I have observed about LED-based products. Now that LED-lighting industry has been around for few years and gaining strength, it is good time that a global standardization organization steps up. Control over the emission angle, uniformity of the optical-energy distribution, intensity levels suitable for each application areas (i.e., domestic/industrial, advertising: hoarding-height from nearest by-stander, hoarding distance from the nearest by-stander) are some of the parameters and standardization organization must look into. At the present moment, LED-based domestic-lighting industry has not been around for long enough for an extensive study of the long-term eye-safety issues of LED based domestic lighting to be given consideration. However, if we ignore these health concerns now, when the actual health-effects surface in a decade or so on from now, we would be too late to remedy the damage done. Therefore, in my view, it is high time that an industry-wide standardization of optical sources on a health stand-point is given thorough thought.

LED light source looks to be very promising future. I hope the light they emit is good to our children’s eye and do not have any other short or long term side effects. I suggest there should be some standards, certifications, approval authorities and vendors should mark their products accordingly. I may like to introduce few embedded intelligence to this optoelectronic device. At many places in office, mall and home we can have considerable savings of energy by automating on/off control of this LED lamps. Can vendor introduce motion detection and possibly ambient light sensors along with semiconductor switch to these lamps? This will automate switching of lamp and saves energy. Also, is it possible to have these LED lamps with tiny embedded CCD camera and power-line or wireless Ethernet communications to help in introducing security features to places without any additional installation expenses? The communication can further automate the switching and also control variable output intensity. The total cost of lamp should not exceed $5 each.

This Lightcell technology is really very interesting. However, I would like to have further information about the possible bigger sizes of these panels. It is clear that multiple LED's could be placed anywhere along the panel provided the optics for spreading and keeping the light uniform could be maintained per LED group, as well as the thermal management of the whole panel. How much "interference" would there be between 2 or more groups of LED's? There is no info on the Oree site about the driver complexity, although the video Patrick refers to indicates simple drive electronics. Still it would be nice to know now. There is additional info at: http://www2.electronicproducts.com/Fundamentals_of_LED_planar_lighting-article-farc_oree_may2010-html.aspx But the questions still remain. Anyone know how well Oree is positioned to do the manufacturing, or will they have to outsource somewhere?

100 lm/W (on the light guide) is a little hard to decode, but note that Cree recently claimed 208 lm/W for a single LED. http://www.cree.com/press/press_detail.asp?i=1265232091259 This pushes LEDs well ahead of fluorescents.

The combination of stable technologies repackaged in an innovative fashion to solve a real-world problem in a hot market is hard to ignore. Add to that the backing of on of the world's largest suppliers to that market and it seems Oree and its planar lighting technology would seem to have a good future. What do you think?
