A little humor:

News & observations on the LED / Solid State Lighting markets:
Opinion: Is your LED glass half empty or half full? That depends on what you have to sell… if you have an extensive line of glass lamp technology that is leading edge for it’s capabilities, like Osram, your LED glass is half empty per their news story below. While CFL and LFL is very energy efficient in terms of lumens per watt, it does have its limitations and the current state of the art is ~120 lm/w. Osram also has some great LED technology but they have been more focused on developing LED packages that support their current non-lighting customers, which has in turn slowed their development of LED lighting solutions. If you are GE (story also below), it looks like your LED glass is half full, by promoting a series of low output LED lamps. However they are putting a positive spin on these under performing products and they have won commercial business lamp sockets with these products. It does look like they are focused on selling LED lamps and modules moving forward. If you are Cree, and everything you do is about LEDs, your LED glass is always full and perhaps overflowing… not only are they at production capacity on existing products, they are once again pushing the limits of the lm/w for white LEDs per their press release below.
So, is your LED glass half empty, half full or over flowing?

LED lighting still too costly: Osram CEO - Demand for super-efficient LED lighting and other energy-saving lights will grow next year as both consumer awareness and the U.S. stimulus package spark sales, the head of Siemens AG-owned Osram Sylvania said on Wednesday. While Osram Chief Executive Rick Leaman expects it will take five to 10 years for LEDs to take off, he sees growth in 2010 for "bridge technologies," such as halogen and compact fluorescent products, to help with the transition from traditional lighting and its phase-out starting in 2012. "The incandescent bulb has been around for over 100 years. Consumers have become very familiar with that light bulb, with the shape, with the feel, with the lighting," Leaman said in an interview. "We believe it's important to provide the consumer with choices." The unit of the German conglomerate that he runs is the world's second-biggest LED producer by sales. In 2008, Osram saw 12 percent of its global sales from LED products, or about 552 million euros. Despite the clear benefits of LEDs, the technology is still too expensive, which would prevent a widespread take-off of the market for another five to 10 years, he said. "The value proposition doesn't add up. It's an expensive product today .... The 40 watt (LED) replacement that we have on the market today -- $35," Leaman said. "We need to target a number of around, I would suggest, $10 for an LED replacement," he added. "At that point you can, to some degree, justify the value of the product versus a standard incandescent product." The company racks up about 60 percent of its sales from energy-efficient products and plans to increase that to 80 percent by 2012. Its sales of energy-efficient products in 2010 could increase 5 percent to 10 percent, Leaman said. The executive sees incentives in the U.S. stimulus package for commercial buildings, school districts, colleges and other groups to invest in lighting as a "jump start to more installations for energy-saving lighting." Osram hopes to capture about $100 million in sales from the stimulus package, Leaman said. http://www.reuters.com/article/idUSTRE5B15OP20091202
GE LED Light Bulbs Now Available for Homes, Small Offices - Home-based workers, businesses, and small offices can now take advantage of the newest energy-efficient way to illuminate interiors and exteriors: light-emitting diodes. GE has created Energy Smart LED bulbs that are available for use in the home, as well as in commercial settings. LEDs are vastly different from traditional incandescent, fluorescent, and neon light sources, says GE. They use significantly less energy both directly via power consumption and indirectly through reduced heat load while giving off a cool, white light that’s perfect for accenting artwork or highlighting interesting architectural details like coves or archways. LED bulbs also are great for areas that need accent illumination such as stairways. The 10 watt GE Energy Smart LED lamp produces 340 lumens and offers up to 80 percent energy savings compared with 45 watt standard incandescent R30 bulbs (485 lumens) or 50 watt halogen PAR30 bulbs (630 lumens). The seven watt GE Energy Smart LED lamp produces 200 lumens and reduces energy consumption by 77 percent when compared with standard 30 watt incandescent R20 reflectors (200 lumens). If a user can reduce light levels, the seven-watt LED lamps could replace halogen 50 watt PAR20 bulbs (570 lumens); they both feature a 20,000–hour rated life. The LED units have other benefits. They are durable solid–state devices, meaning there is no filament to break. The longer rated life of LEDs minimizes maintenance hassles and costs. GE is also giving existing LED lighting in commercial and residential settings the same twist convenience. It has come up with a small puck–shaped LED module that provides a one of a kind ease of installation, which is a clockwise twist motion into its socket that makes the necessary thermal and electrical connections. This contrasts sharply with current integrated LED luminaires and modules that are not easily replaceable because they require mechanical fasteners to couple the LED package to a heat sink, and a plug to make the electrical connection. GE‘s replaceable LED module allows fixture makers to remain current with the latest LED performance. “It is as easy as changing a light bulb,” said Steven J. Briggs, vice president of marketing and global product management with GE Consumer & Industrial‘s LED business, Lumination, LLC. “Leading lighting designers and architects are on the record with concerns about integrated LED fixture upgradeability and serviceability. Some won‘t specify an integrated LED fixture. This is GE‘s answer. It‘s future-proof and market-ready.”

Cree Achieves 186 Lumens per Watt from a High-Power LED - High-performance chip and R&D package combine for record-setting efficacy Cree announces it has achieved industry-best reported R&D results of 186 lumens per watt for a white power LED. This result demonstrates Cree’s continued focus on pushing the performance of its LEDs. Cree’s tests confirmed that the LED produced 197 lumens of light output and achieved 186 lumens per watt efficacy at a correlated color temperature of 4577K. The tests were conducted under standard LED test conditions at a drive current of 350mA, at room temperature. “This result is a testament to the tremendous progress Cree has made this year,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “As energy efficiency becomes increasingly important in addressing our nation’s energy challenges, Cree is doing its best to deliver the most energy-efficient LED technology possible.” While this level of performance is not yet available in Cree’s production LEDs, Cree continues to offer volume quantities of the industry’s broadest family of 100+ lumen LEDs. http://www.cree.com/press/press_detail.asp?i=1259701233981
