LED lighting is not just about lighting any more. What researchers have been working on is to use LED lighting for wireless communication as well.
Below is the link to a good article that describes the research in this area.

(Old) News on Global Mercury Ban
People have talked about how toxic Mercury is and how one should not just dispose items that contain Mercury to trash cans. Why? Because Mercury wastes can infiltrate into the soils and contaminate the ground water systems. The mere thought of that possibility should have you think twice about throwing your CFLs to the trash cans.
I used to just treat the CFLs like any other trash, but after learning that Mercury is hazardous to the environment, I stopped doing that. Nowadays, I carefully put the CFLs that went bad to a designated box. You don’t want to throw them, ‘cause you don’t want to inhale Mercury vapor should you break the CFLs. My box is getting rather full already. To be honest, I don't even know where to throw them. I have talked to a few people, and they don't know either. When they are asked how they deal with dead CFLs, they said they just put them in the traditional thrash cans. That is not good, people!
Exactly how toxic is Mercury? A recent news announcement on global Mercury ban from the United Nations has the following in their article:
“UNEP noted that mercury and its various compounds have a range of serious health impacts, including brain and neurological damage especially among the young. Others include kidney damage and damage to the digestive system. Victims can suffer memory loss and language impairment alongside many other well documented problems.”

The Significance of Our “Film-Covered LED Device” Patent
The patent, Film-Covered LED Device, has been granted in the United States!
Here are a few significant facts of Andromeda LED Lighting's “Film-Covered LED Device” Patent:
Our patented technology produces high efficiency of white light and sidesteps two main categories of LED lighting patents in the LED industry-- White Light LED Phosphor and High Power LED Packaging.
Our technology streamlines the manufacture process, thus reducing production costs and increasing product quality simultaneously. The defect ratio is less than 1%!
High luminous efficiency of warm white light
Color temperature deviation is less than 30 degrees. The margin of error in the CIE chromaticity diagram is extremely small, maintaining color consistency.
Because of this design, the light source gives out areal light, as opposed to the light cones by competitors' LED point light sources.
The advantages are 1) less heat generated (warm to the touch) 2) longer lifetime 3) uniform light 4) esthetically appealing 5) maintaining constant light output (lumens) for a much longer duration of time
No phosphor is needed to cover the LED chips. It is replaced by a film covering the LED chips to produce the desired light colors.
