DOE Releases Life-Cycle Energy Consumption Report - Incandescence vs. Fluorescent vs. LED Lamps

The U.S. Department of Energy (DOE) has published a report comparing the energy consumed over the entire life cycle for LED lamps, compact fluorescent lamps (CFLs), and incandescent lamps. Entitled "Review of the Life-Cycle Energy Consumption of Incandescent, Compact Fluorescent, and LED Lamps", it is based on existing life-cycle assessment literature of lighting products.

New to our miniature converter range is the SKA20 series

Following the launch of the SKM15 series and the growing demands for miniaturization applications, MeanWell introduced the SKA20 Series, a 20W module, single output regulated DC/DC converter. At a size of 2”x1” it is designed to suit miniature applications and also helps system designers solve the issue of PCB space limitation.

With up-to-date high efficiency circuit design the SKA20 series has up to 89.5% efficiency, free air convection cooling; allowing full load operation from -40°C to +75°C ambient temperature and up to +85°C by derating the output load. They have standard pin assignment for Dual Inline packaging and feature a 2:1 wide input range and 1500VDC input/output isolation.

The series includes short circuit, overload, input and output over voltage protections, low ripple noise, remote ON/OFF control, remote sense, external trimming output and CE/FCC compliance. In addition, it features fully encapsulated packaging which can help them withstand the influence of dust and moisture from various environments. Suitable applications include industrial control, telecoms and distributed power architecture related applications.

New Cree MT-G LEDs Deliver Unmatched Brightness, Color Quality and Consistency

Pushing LED brightness, color quality and consistency to new levels, Cree, Inc., a market leader in LED lighting, announces another step in eradicating today’s energy-wasting halogen light sources. New XLamp® MT-G LEDs deliver higher brightness levels, unparalleled color quality and proven lighting-class reliability.

Cree Redefines High-Voltage LEDs

Cree, Inc., a market leader in LED lighting, announces the commercial availability of high-voltage XLamp® XT-E and XM-L LEDs. These new LEDs can enable the use of more efficient, smaller drivers to lower cost for compact lighting applications such as candelabras and retrofit lamps.
Small-form-factor lighting, like candelabras, historically presented a host of challenges for LED technology. Prior LEDs were unable to deliver the required system-level performance in the form factor consumers’ demand.

“Maximizing the LED voltage, as Cree has done in the new high-voltage XM-L and XT-E LEDs, is a very effective way to minimize current through the LED driver output rectifier,” said Peter Vaughan, director of applications engineering, Power Integrations, Inc. “This can reduce losses and heat dissipation in the driver and increase the overall system luminous efficacy by several percentage points.”

“Never before have lighting OEMs been able to leverage the benefits of high-voltage LEDs with this level of performance,” said Paul Thieken, Cree director of marketing, LED components. “We continue to develop the right LEDs for the right applications—to accelerate the adoption of energy-efficient LED lighting.”

The XLamp XM-L LED delivers up to 600 lm in Cool White (6000K) and up to 462 lm in Warm White (3000K) at 6W, 85°C. The XLamp XT-E LED delivers up to 300 lm in Cool White (6000K) and up to 228 lm in Warm White (3000K) at 6W, 85°C. Both LEDs have a typical voltage of 46V at binning conditions.
