Don't light up my life with a CFL

Readers of the print EE&T Magazine will soon be getting their issues in the mail, but you can also read the digital rendition here if you can't wait.
In it you'll find an account of my own ill-fated first experience with a CFL. There will be much more satisfying bulb technologies discussed at our Illumination Summit kicking off on Thursday in Orlando. Meanwhile, send your energy efficiency news to us at [email protected]

More progress for electric superbike

We recently wrote about what is billed as the world’s most powerful and technically advanced electric superbike that went head-to-head against conventional gasoline-powered race bikes in a professionally organized roadrace at the Auto Club Speedway in Fontana, Calif. After finishing in third place in this outing, bike developer Chip Yates reports he is further upgrading the bike with a bigger, 240-hp electric motor, and with anti-wheelie software so the front wheel isn't so prone to come off the ground as the bike accelerate.

Rugged Speed and Temperature Sensor
Electro-Sensor's TT420 Temperature Transmitters and ST420 Shaft Tachometers are pre-calibrated, proven solutions that install fast and perform anywhere, providing rugged and reliable monitoring solutions for your toughest machine environments. The TT420 combines a temperature sensor, signal conditioning, and 2-wire loop-powered 4-20mA transmitter into one compact package. The ST420 detects magnetic pulses from a rotating shaft-mounted magnetic pulser target (disc or wrap) and outputs a smooth, continuous 4-20mA analog signal in direct proportion to the pulse frequency (rotating shaft speed).

Combo transistor/memory cuts energy use by orders of magnitude

A newly developed logic device called the “atom transistor” is said to perform both logic and memory functions while reducing power consumption to 1 x 10-6 that of the conventional devices. In contrast to conventional transistors, which control the movement of electrons in a semiconductor, the newly-developed “atom transistor” operates by transferring a small amount of metal atoms in an insulator.

Featured video: Electric hub motors for pickup trucks

Hub motors are more than just laboratory curiosities. Tom Prucha from Protean Electric describes the operation of their 84-kW hub motor as demonstrated on a four-wheel drive F-150 pickup. Length: 5:00


LEDs going on the toxic list?

Light emitting diodes aren't considered toxic -- yet. But that may change if legislators take heed of new research from the University of Calif. at Irvine. Oladele Ogunseitan, chair of UC Irvine’s Dept. of Population Health & Disease Prevention has led a team that crushed, leached and measured the tiny, multicolored LEDs sold in Christmas strands; red, yellow and green traffic lights; and automobile headlights and brake lights.

Vishay's Ambient Light Sensors are Ideal to Detect Light and Brightness
Vishay's ambient light sensors are used to detect light in a manner similar to the human eye. These sensors are most commonly found in industrial lighting, consumer electronics, and automotive systems where they allow device settings to be adjusted automatically in response to changing ambient light conditions. Available as phototransistors and photodiodes, Vishay’s portfolio of ambient light sensors is one of the broadest on the market. Sensors are available in seven different packages including leaded, surface mount, and hermetically sealed.

LEDs bright enough for spotlight duty

Sharp Corp. says it has developed a high-output, high-color-rendering 25-W-class LED boasting an industry high luminous efficacy of 91 lm/W. The intended application for the new devices is in light sources as used for store spotlights. READ MORE
