San Jose, CA —There's a new record in efficiency for LEDs. According to LumiLeds Lighting (a joint venture of Agilent Technologies and Philips Lighting), its latest InGaN (indium gallium nitride) devices have wallplug efficiencies (WPE) of 25% at 425-nm (purple) wavelength, running at 250 mA dc. The previous reported industry record was 22%. WPE is considered a "real world" quantity, measuring optical output power divided by electrical energy input. The devices emit more than 200 mW of optical power.
Frank Steranka, LumiLeds materials R & D and product development manager, adds, "We are exhibiting up to 55 lumen devices in certain colors." Applications in-clude LCD monitors and TVs, with brighter colors and lower pow-er consumption, and consumer uses such as flashlights.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
Independent science safety company Underwriters Laboratories is providing new guidance for manufacturers about how to follow the latest IEC standards for implementing safety features in programmable logic controllers.
Automakers are adding greater digital capabilities to their design and engineering activities to promote collaboration among staff and suppliers, input consumer feedback, shorten product development cycles, and meet evolving end-use needs.
