Destination of recycled Mercury

Found it today browsing my scrap notes.

"Tens of thousands of remote mining sites have sprung up mostly in Asia, Latin America and Africa, using as much as 1,000 tons of mercury each year...

...Mercury comes from the dozens of companies in Europe and the United States that recycle the metal from old light bulbs, batteries or industrial waste, according to the U.N. and the Zero Mercury Working Group."

Busy Receiving Samples

This week we have got some interesting samples.

First was CeramCool ceramic heatsink with circuit board on it. Its made from thermally conductive and electrically insulating high-tech ceramics like Rubalit (Al2O3) or Alunit (AlN).

Then new PAR20 and PAR38 lamps from LEDTronics.

And finally Optodrive LED modules from Swedish company Optoga.

Reviews will be available soon. Please comment on this post if you have any particular question about these products..

Ideal press release as I see it

Recently Honeywell published press release about new thermal interface material called Honeywell LTM6300-SP.

In a page long text a short message is being repeated over and over again in many different ways. ("New thermal interface material LTM6300-SP was developed.") That's it.

It would have been helpful if the press release had said anything significant about the performance characteristics of the material. Instead, it provided a link to a Honeywell Web site whose only reference to the material is the press release. Vicious circle.

Overall it's a common problem for many press releases.

Ideal press release as I see it:

-Name, part number and purpose of the product
-Quick list of most important features
-Availability date
-Link to a datasheet

One paragraph max.

It's time for PR people to realize, that "old school" press release format is not suitable for Internet era.

IIDEX/Neocon & Light Canada 2009 Seminars Preview

[F20] Taking It to the Streets: Using LEDs for Outdoor Lighting Applications (IES)
Friday, September 25, 2009, 2:30 - 3:30 PM
CEU 0.1

This session will cover the basics of LED lighting technology and standards for photometric testing and life ratings, provide guidelines for effective evaluation and specification of LED luminaires, and review case studies in Canada and the U.S. focusing on commercial exterior lighting.

Speaker: Shirley Coyle, LC, is president of Ruud Lighting Canada/BetaLED, a manufacturer of commercial luminaires for exterior and interior applications, including an extensive offering of LED luminaires. She has worked for several international lighting companies in her 26 years in the industry. Shirley is active in IES as a past president of the Toronto Section, chair of IES District 1, and a member of the IESNA Street and Area Lighting Committee.

[F33] Rethinking Lighting - The LED Promise (IES)
Friday, September 25, 2009, 11:45 AM - 12:45 PM
CEU 0.1

LED lighting systems have advanced at remarkable rates. For the lighting designer, it is critical that the performance attributes of LED systems be well understood and this presentation pulls all the pieces together.

Speaker: Martyn Timmings, LC, is vice-president of market development for Canlyte. He focuses on Lightolier Lighting Controls and Color Kinetics LED in Canada, and has been involved for more than 20 years in lighting education and demonstration programs. He is a past president of the Illuminating Engineering Society and a recent recipient of its Distinguished Service Award.

Voices for SSL Efficiency 2009

The DOE hosted a workshop Voices for SSL Efficiency 2009 in Chicago on July 13-15. Unfortunately for me it overlapped with SemiconWest 2009 which I attended in San Francisco.

In this post I will try to gather feedback from people who attended this event.

Ted Konnerth, Ergret Consulting
Several issues struck me as noteworthy:

Energy Planning. A representative of the State of California (the 8th largest economy in the world) gave an interesting talk about the impacts of clean technology and energy conservation. California enacted strict energy conservation legislation following the original 'gas shortages' in 1974. Since 1974, California's consumption of electricity has remained virtually flat; for 35 years! The US consumption has increased over 50% in that same timeframe.

- Energy requirements. The projected generation capacity required for the US over the next 10 years is an additional 135,000MW, solely to keep up with demand. Currently there are projected capacity additions that are in approval process to add 77,000MW, leaving a shortfall of 58,000MW to meet demand. 58,000MW is the equivalent of 110 power plants (typically coal or gas). The US would need 1 new plant every month for 10 years to meet that demand.

Working hard on creating LEDs Review community

We are moving to a new platform to implement social networking.

We invite SSL industry experts to start your own blog here, at Share your thoughts and news. Discuss LED related topics in Forums. Or just socialize.

Final issue of Compound Semiconductor Magazine

IOP Publishing, the owner of Compound Semiconductor magazine and the web site, has ceased publication of the title. When I picked the latest July issue at Semicon West, I didn't know it was the last one.

Best wishes for the future to the CS Mag editorial team and thank you for coverage of virtually all aspects of semiconductor industry and R&D landscape by means of a well-composed, well-informed, exhaustive and enjoyable magazine.
