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.
Some cars are more reliable than others, but even the vehicles at the bottom of this year’s Consumer Reports reliability survey are vastly better than those of 20 years ago in the key areas of powertrain and hardware, experts said this week.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
While many larger companies are still reluctant to rely on wireless networks to transmit important information in industrial settings, there is an increasing acceptance rate of the newer, more robust wireless options that are now available.
