One LED story to note, from our Research.Materials section: Kyushu University reports liquid-OLED

Writes our Technology Editor, Steve Bush:
Scientists at Kyushu University in Japan have reported liquid-OLED in a recent issue of Applied Physics Letters.
In cells sandwiched between sheets of glass - much like an LCD - Denghui Xu and Chihaya Adachi mixed hole carrier ethylhexyl carbazole with rubrene which is both an electron carrier and photoemitter.

Niche product of the week award goes to ...

It surely has to go to the LT-2000 series LiteTracker Bikelite, 'the latest development from the LiteTracker range for indication and illumination in explosive atmospheres'... specially for people who like to travel by bicycle in such hazardous locations as chemical sites.

From a practical point of view it's not actually such a daft idea. This LED light can be used as a personal indicator to identify the position of workers in confined spaces or it can switch to torch mode and be used as a mini flashlight for close inspection work. Handy in the pub on Quiz Night. It's even sealed to IP67 - perfect.

Osram claims first LED-based replacement for 40W bulb

Osram LED 40W replacement bulb.jpgWe report today that Osram is producing what it claims is the first LED-based replacement for a 40W bulb.

Dubbed Parathom Classic, the bulb consumes 8W and produces 345 lm at a colour temperature of 3,000K. Lifetime is claimed to be 25.000h.

"This is the very first bulb shaped LED lamp which constitutes a true substitute for a 40W incandescent lamp," said Christian Schraft, head of consumer lighting at Osram.

LED solar lamp.jpgHere's another one that got my attention, on a recent gadget trawl: a glowing solar LED lamp. What are the chances of this one catching on?

Thanks to Technabob for flagging this one. Available through the Japanese Idea Online shop (for ¥1,575, or approximately £10), these little objet d'art stand three feet tall, and gain their power from solar energy.

They're also available in pink, orange and white.

topless oled desk lamp.jpgProject TOPLESS is creating Polymer-OLED desk lamp prototypes, reports OLED-info.com:

"The OLED lamps have five 2" P-OLED panels, each requiring 0.7W (the total power input is 3.5Watts - 5V dc @ 0.7amps)," it writes.

"TOPLESS (Thin Organic Polymeric Light Emitting Semi-conductor Surfaces) objectives include an efficacy of 20Lm/w, color temperature suitable for general white light applications and large single-pixel devices. TOPLESS will run till February 2010."
