When Will OLEDs be the Next Big Thing in Lighting?

Stephanie Pruitt 10/08/2014

OLEDs have been gaining in popularity lately, mainly in displays, but also more recently in general lighting. They offer many benefits over traditional and LED lighting, including being a surface emitting light source (as opposed to point emitting), being extremely thin, and having the capability to be flexible and even transparent. OLEDs open the doors to really innovative and creative light forms that were previously not possible with traditional lighting. However, they still have a ways to go in efficacy, lumen output, and price compared to their less expensive inorganic counterparts that are still struggling to really penetrate into the market.

High-End Lighting Markets for Solid State Lighting

Shonika Vijay 09/30/2014

Lighting has always been seen as a commodity market. In fact, most people buy their light bulbs from the same place they buy their milk. It is a price war out there with slim profit margins on lighting products; meanwhile, the market keeps demanding higher quality. The general indoor lighting market mostly consists of the following form factors: downlights, troffers, suspended pendants, track lights, and high bay lights (a detailed market report of general lighting luminaires with these form factors along with all technologies will be released this November). Downlights and troffers make up the majority of the installed luminaire base for all regions. In order to compete for penetration in these installed luminaire bases, LED lighting has had to slash its prices while making sure it can sustain the light output levels of halogens, incandescent, and fluorescent technologies.

Fiber Laser Market Continues to Evolve

Allen Nogee 09/05/2014

I’ve always been a person who has been very interested in the latest technology, and sometimes it’s hard for me to believe how much technology has changed over the years.

Everything from flat screen TVs, DVRs, audio equipment, cables and wiring, computers, tablets, smartphones, and so many others have evolved over the years, and in most ways, the new technology is quicker, smaller, cheaper, and more energy efficient. Today we take all these things for granted, but it wasn’t that long ago that a flat screen TV or a smartphone was a novelty. Today we just can’t even imagine living without these things.

A Win-Win Situation: Cree Announces Investment in Lextar through Private Placement

Martin Shih 09/05/2014

Cree recently announced plans to invest US $83M in Lextar Electronics, one of Taiwan’s major LED manufacturers, in order to acquire 13% of Lextar shares and to enter a supply/royalty agreement. Cree will become Lextar’s second largest shareholder (AUO, Lextar’s parent company, is the biggest shareholder) and obtain one member of BOD. This deal is expected to be done at the end of 2014 and the lock-up period is 3 years, which means Lextar will reserve its capacity for Cree for 3 years.

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.

Breaking down the "micro" laser market

By Tom Hausken
We just published our special market report on the so-called micro materials processing market . Once the market bounces off the bottom, the growth in the recovery will be good, but the interesting part of the story will be in changes in market share as the technology marches forward.

I should first explain what the micro materials processing market is. These are lasers used for lower power welding, cutting, drilling, microfabrication, additive processes, heat treatment, and lithography. We don't count kilowatt lasers at all, nor do we count marking and decorative engraving. The lasers are used to make semiconductors, solar cells, medical devices, jewelry, electronics, consumer products, and a wide range of various industrial parts.

The market will take a 40% hit this year, which is dreadful, but this is not big news any more, and the recovery will bring the market to $460 million by 2013. There is talk that the semiconductor tool business is already turning around, after falling since 2007. Other markets, like solar cells, has a ways to go yet, and automotive may be slower to come back.

We found the market share leaders to be Coherent, Rofin-Sinar, and GSI Group, with over 50% of the market. It's not hard to see why. Coherent is strong in CO2 lasers, excimer lasers, and DPSSLs. Rofin is strong in multiple categories too (don't forget that Rofin includes other brands: Lee Laser, etc.) And we counted all of Excel Technology's laser production in GSI's 2008 share, so that includes significant lamp-pumped solid-state lasers and CO2 lasers. There are a lot of players and product segments, so any company that is strong in multiple segments will have greater share. (Of course, many companies are also diversified across other laser applications apart from the micro category, but that isn't counted here.)

By the way, lamp-pumped lasers may be on the decline, but the sales still amount to something, especially considering that they often involve higher powers, and therefore higher prices. By comparison, a lot of CO2 marking lasers sell for under $2,000, so it takes a lot of them to amount to much.

The thing that is striking is that the technology, as mature as it is, isn't staying still, especially in the micro category. Innovations like pulse shaping fiber lasers, higher power green lasers, and picosecond lasers, to name a few, promise to upset the market share at least a little while the market comes back.
