Check out this article! Laser-based general illumination? I'm skeptical about it but it sounds cool at least. Hopefully it doesn't eliminate traditional light fixtures altogether though.

I genuinely don't like this, I could accept led's when they came out but this is just uneccesary. The issue I have is it being totally socket less, yes they make led's like this but as far as I'm aware that's more in a commercial setting, I certainly don't want to be replacing an entire home fixture... Screw that mess, they better make these things like light bulbs. Or better yet stick to a technology that they still have yet to perfect, peoples impatient astounds me, Atleast in these types of situations.

Sounds very unrealistic in near future and just some wild visions. Not in next 10 years. Also, what benefit would there be using single hi power laser and fiber optics. Wouldn't that mean the laser would use same amount of power even when there would not be need for lighting in certain area of building.

I don't also understand the fixation in wholly evenly illuminated ceiling. I would consider something like that ugly but many "future of lighting" article features such idea.

There is a sort of rush to "redefine the perfect lighting" that largely started with LEDs. Forget proper optics and so, uniformity is the most important thing ! What we see here is still the same thinking applied to a potential future technology

I generally see all the eye strain problems from LEDs except getting worse

What are they going to cost and how are they planning on dealing with phosphor degradation, sure you can get 2000 times the light from a laser diode, so the phosphor will degrade faster as well, I guess we will wait and see what happens, but it should make high power blue laser diodes even cheaper...   

Photobiological safety of the Blue line coming through, and the light reflected off shiny surfaces

Yeah I don't like the idea of everything moving toward concentrated light sources. These concentrated light sources have more glare and are more harmful to the eye. Nothing beats the softness of a T17 fluorescent or a giant G40 incandescent lamp. Those lamps are so diffuse and easy on the eyes yet do a fine job of lighting a room too!

Digital projection uses laser light engines in some of their 3 chip DLP projectors. They work pretty good and have low maintenance costs vs UHP Mercury.

Laser projection lighting-RBG lasers give the best results.Christie,Barco come to mind as the users-and IMAX.The IMAX  film replacements don't equal their 15/70 film systems.SAD-many of those fine peices of projector engineering have gone to the scrappile in favor of inferior digital projection.For replacement of 35MM film in commercial cinemas-digital is OK-but for large film formats forget it.The laser lighting is a good replacement for the high pressure Xenon lamps-a bomb in your projector lamphouse!The lasers use less power,last longer-no high pressure lamp hazards.Sony now makes a home type projector that uses phosphor lasers-not RBG.

Yea DP (digital projection) has a setup that uses two blue lasers with some phosper wheels and stuff (magic) to create a high CRI white light that is then fed into the usual 3 chip DMD prism setup to do RGB. The whole thing is sealed and water cooled. I've installed two of the highlite lasers and they have really rich color. You can also tell that it is laser powered if you get close to the screen, you can see a small amount of noise in the light that lasers produce. The projectors themselves are quite a bit heavier than their UHP counterparts on account of them being way more dense.

One thing is for certain, Diodes are here to stay for a very long time, whether it be standard LEDs as we know them today, or DPSS lasers like in the article. The LED currently has exceeded every other light technology in efficiency and the high power LED has only been on the market for 10-12 years. Using lightguide pipes reminds me of the microwave sulfur plasma lamps that were developed in the late 90's and never went anywhere.

has not exceeded LPS yet, the best ones can hit 200 lumens per watt, probelm is nobody seems to like them anymore

For laser projection lighting Christie,Barco(Cinema projectors) use separate lasers for the Red,Blue,Green.This give the best quality and efficiency over the phosphor based system .The RBG is more expensive.If you want a Christie RBG laser projector---its only $275,000!IMAX uses a similar system.For the Christie system depending on the size of the screen-the projector has rack mounted laser modules of each color-4 or 6.Their outputs are combined and fed into the projector with a VERY large fiber optic cable.The laser module racks are cooled by large blowers.

Video projectors have really come long way. Still remember those big, heavy and noisy CRT projectors that were used once.

In projection the scene information is allready very limited after conversion by a camera, processing, and conversion by the LCD matrix. 3 specific color bands and finite number of brightness level (8 or other) in each color. This is not comparable at all to what we see with our own eyes. The lighting requirements for projection are entirely different than what we want to expect from lighting used for lighting
