Power Conversion for Reduced Cost, Volume, and Weight - and Increased Efficiency

Industry and consumers are increasingly aware of the benefits of efficacious use of metered power, as costs and cost trends increase. Making the right choices for power converter design can produce rapid investment payback in applications such as for LED illumination and automotive electric vehicles, and can be optimized for low total cost of ownership (TCO).

Keep Lighting Green from Start to Finish With Proper Packaging and Disposal of Used Fluorescent Lamps

Fluorescent lamps are a popular lighting option for businesses and consumers that are looking for ways to conserve energy and cut down on wastes. Since mercury - a very useful but very toxic element - is used to conduct the charge in fluorescent lamps, these benefits can come at a significant environmental and health risk.

Reflective Switch Employed in Wind Turbines for RPM Sensing

The OPB732 Series long distance infrared reflective switch from TT electronics OPTEK Technology (Carrollton, TX) has been employed in a 6kW wind turbine for RPM sensing. Placed at the turbine rotor, the switch is used internally to sense RPMs, and that data is then transmitted to a customer-accessible Web site via GPRS.

Research: Reducing Energy Consumption in Street Lighting

Experts from Rensselaer Polytechnic Institute's Lighting Research Center (LRC) estimate that about half of the approximately 13 million streetlights in the U.S. have the opportunity to reduce energy consumption by 50 percent - translating to an annual savings of 1 billion kWh, and a reduction in power plant CO2 emissions of 546,000 tons per year.

LED Characterization System

As part of the design process, engineers must predict the performance of their LED system and determine if it will meet specifications at real operating temperatures and electrical drive conditions. The ETΦ™ family of LED Characterization Systems (also known as ETO) from Orb Optronix (Kirkland, WA) measures the complete electrical, thermal, and optical characteristics of LEDs.
