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

Compared to CFLs and Incandescent iamps, today's LED lamps clearly use most energy in the manufacturing process, but the life-cycle energy consumption is on par with CFLs and 1/4 of incandescent lamps. Until 2015, LED lamps are expected to half the life-cycle consumption again 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. Read more »

The Maastricht University Medical Center+ and Philips Investigated the Effect of Light on the Sleep-Wake Rhythm of Cardiac Patients

The research shows that after seven days in a patient room fitted with HealWell ? a new lighting system developed by Philips which mimics the natural day/night cycle outdoors ? patients sleep on average 8% longer. After one week in a patient room fitted with standard lighting, on the other hand, patients' sleep duration was in fact slightly shorter than on the first night. Read more »

EU Project IMOLA Starts R&D on Large-Area, Intelligent OLED Lighting

Transparent organic light-emitting diode on foil (Courtesy of TNO/Holst) Imec and its project partners announce the launch of IMOLA (Intelligent light Management for OLED on foil Applications), a project under the EU’s 7th framework program for ICT (FP7). The project’s goal is to make large-area OLED-based lighting modules with built-in intelligent light management. These systems will be used in future energy-efficient wall, ceiling and car dome lighting, where the light intensity can be adjusted intelligently, e.g. according to the time of the day or weather conditions.

Independent Research using Xicato Spot Modules: Link Between Light Quality and the Attraction of Retail Displays

Figure 1: The competing light sources (Halogene, standard CRI~80 LEDs and high CRI~95 LEDs) There is a strong link between the quality of accent light sources, in terms of color rendering ability and in particular the rendering of deep reds, and the attention-grabbing potential of retail displays, according to the outcome of an on-site evaluation by end-users and lighting designers conducted by independent researcher, Colette Knight and peer reviewed by University College London. Shoppers and lighting designers took part in the experiment carried out in a House of Fraser store in London. It showed that there was no statistical difference between the appreciation of colors rendered with halogen or Ra 95 (R9 >95) LED sources, whereas the rating was lower for Ra 80 (R9<20) LED sources. This translated directly into the rating of the display itself in terms of its attraction. Read more »

Studies Published on Flicker Perception from SSL Systems - ASSIST to Release Related Recommendation

The contour plot figures below show mean detection percentages (left) and mean acceptability ratings (rigth), both as a function of frequency and percent flicker (click on image to see the full plot) Flicker and stroboscopic effects have been a concern with solid-state lighting (SSL), and industry and the ENERGY STAR program have debated recently the effects of frequency and other driving modes on the perception and acceptability of flicker. To provide further data and guidance in this area, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has conducted human factors studies of flicker that were recently published in the Lighting Research and Technology journal. The studies, funded by the Alliance for Solid-State Illumination Systems and Technologies (ASSIST), will become the basis for future ASSIST recommends guidelines on flicker from SSL systems.

UCI Researchers Find LED Products Billed as Eco-Friendly Contain Toxic Metals

LED products usually are electronic products that should be handled as electronics scrap if disposed, anyway. A realease of potentially hazardous substances under regular use is very unlikely, even when broken. LED professional does not agree with the generalized conclusions of this research. However, it is important to challange statements of PR and lobbies to boost more eco-friendly products. In fact, light-emitting diodes of tested holiday bulbs, traffic lights and car beams marketed as safe, environmentally preferable alternatives to traditional lightbulbs actually contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research.
