Lasers in Medical Imaging: The Forecast Looks Very Bright

Allen Nogee 07/11/2014

Almost all medical imaging to date has used one of three technologies: X-rays, magnetism (MRI), or ultrasound. X-rays alone have been used for almost 120 years now, and although today’s imaging technology has improved vastly over the many years, the fact remains that x-rays, ultrasound, and magnetism are all technologies that, due to many factors, produce coarse images, at least by today’s standards. But what if a very coherent light source was used instead, maybe a laser?

Actually, Optical Coherence Tomography (OCT), which produces images based on the reflections of coherent light, is not a new technology. OCT has been used since the early 1990s, especially in the area of ophthalmology, where the images produced by OCT are 100 times finer than standard images produced by ultrasound. In just the last five years, OCT has become one of the most important retinal imaging techniques used today.

The Impact of the Epistar Acquisition on the LED Industry

Martin Shih 07/09/2014

Epistar (2448.TW) announced a plan to fully acquire Forepi (3061.TW), the second-largest chipmaker in Taiwan, through a share swap (1:3.448), implying 18% share dilution to Epistar. The effective date will be the end of 2014, and Forepi will be delisted from the TAIEX.

After the merger, Epistar will become the world’s largest LED chip maker in terms of capacity with a global market share of 15%, which will better position the company to lead in future technology development.

EPA's New Emissions Cutting Plan Could Have an Effect on LED Lighting

Philip Smallwood 06/30/2014

On June 2nd, the Environmental Protection Agency (EPA) proposed a rule designed to cut carbon dioxide emissions from existing coal plants by as much as 30 percent by 2030, compared with 2005 levels. The EPA will finalize the proposal in mid-2015 and then give states a year to design their own plans to meet targets. The organization will let states meet emission targets for power plants in several ways, including through plant upgrades, by switching from coal to natural gas, by improving energy efficiency, or by promoting renewable energy outside the plant site. This approach will give states greater flexibility in designing plans to meet the EPA’s targets.

Where's the Glare?

Shonika Vijay 06/13/2014

LIGHTFAIR, the world’s largest annual architectural and commercial lighting trade show and conference, took place in Las Vegas last week. I wanted to share my thoughts on what I saw that was of the most interest. The 3 main things I saw were: a lot of LED luminaires, more use of optics in products, and lighting controls being present in nearly every booth. To read up more on controls, please see our blogs: Let's Talk Controls and Lightfair International Gets Smart. I will focus on what I saw in terms of optics and LED luminaires.

Lightfair International Gets Smart

Stephanie Pruitt 06/10/2014

At Lightfair International 2013, it seemed only a handful of companies had a booth with a smart lighting solution - Philips, TCP, and Samsung were among the more recognizable ones that I noticed. Fast forward one year and it seems that smart lighting could be found at almost every booth; even the non-name brand booths seemed to have some sort of solution. Whether this was wireless controls to dim lights or change color through your smart phone - or even gesture control...

What it takes to drive LED replacement bulbs

By Tom Hausken
What does it take to drive a market to high growth in the middle of a recession? Being a drop-in substitute for an existing product helps. Having a feature that no other technology can do helps, too. A government mandate also helps. If all three happen at the same time? Then the odds improve that strong growth will happen. That’s what’s happening in the LED replacement bulb market, as described in our recent report .

Contrary to what you might think, the lighting market has never been completely static. There is a wide range of options for light sources, electronic drivers, and fixture designs, and they continue to evolve. But the sockets themselves are slow to change, since they involve network effects, a form of chicken-and-egg problem. That’s where the drop-in substitute comes in. LED replacement bulb are selling today as substitutes for certain high-value applications.

What high-value applications? That’s where the unique feature comes in. LED bulbs can’t compete with compact fluorescent bulbs for general ambient lighting. But for directional lighting, LED bulbs are superior for controllability, dimmability, and a choice of color temperatures.

Why not use the existing technology? The government mandate requires that all bulbs achieve a certain efficacy over a coming phase-in period. While this doesn’t ban incandescent bulbs outright, it does price ordinary incandescent bulbs above more efficient CFL and LED bulbs. A perfect convergence.




By the way, the terminology in this area can be confusing. The figure shows how the LED replacement bulbs fit into conventional fixtures to complete a luminaire. The eventual goal is to migrate to complete designs where the LEDs are integrated into the luminaire from the get go. (See our market report on LED luminaires .)
