ELECTRONICS:Seoul Semiconductor will introduce the first 100 lm/W AC LED light source during the first quarter of 2010. Offering 25 percent greater efficiency than existing LED light products, this latest offering from Seoul Semiconductor’s Acriche brand will be available for sampling by March 1.Seoul Semiconductor notes that Acriche outlasts incandescent and compact fluorescent (CFL) bulbs, and due to its long life is less costly to use than traditional lighting methods.
Like other Acriche products, the new 100 lm/W LED needs no ac-dc converter. Additionally, it generates less than 1/10th the carbon emissions of an incandescent bulb, an important consideration in meeting new regulatory standards in markets worldwide.
Mass production of the new Acriche will begin in the first quarter of this year.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
