Rich document D source code Cree Expands Design Possibilities for Architectural Lighting with the Worldwide Proven CLQ6A LED
These SMD LEDs are packaged in an industry standard PLCC8 package. These high performance 4 color SMT LEDs are designed to work in a wide range of applications. A wide viewing angle and high brightness make these LEDs suitable for signage applications.
Rich document Measuring the Oxygen Content of Blood with LEDs
Pulse oximetry is a non-invasive method for determining haemoglobin (Hb) saturation through oxygen in the blood and heart frequency. It uses the fact that oxygen-rich and oxygen-poor haemoglobin absorb red and infrared light differently. In order to measure the oxygen content reliably, LEDs with high performance, constant quality and low scattering are needed as light sources. With the WL-SMTW and WL-SITW series, Würth Elektronik has suitable red and infrared LEDs in its portfolio. In addition, there is a matching light sensor available: The phototransistor WL-STTW can reliably detect both red and infrared light.
Rich document text/texmacs Lumileds Boosts Intensity of CoBs for Spotlights and Downlights
Lumileds today introduced three lines of CoBs: the LUXEON CX Plus CoB (Gen 2), LUXEON CX Plus CoB – High Density and LUXEON CX Plus CoB – High Density (Below BBL), drop-in upgrades for Lumileds and competing arrays. The second generation arrays feature industry leading performance and a 14% flux improvement vs. the previous generation. Delivered in a range of light emitting surfaces (LES) (4.5, 6, 12 and 14mm) and correlated color temperatures of 2700K to 5000K, the Gen 2 arrays provide excellent efficiency of above 140 lm/W at 3000 K 80 CRI or 122 lm/W at 3000 K 90 CRI.

Vitrek, the leader in high-voltage test and measurement equipment, introduces the PA920 Series Ultra High Accuracy Power Analyzer. The PA920 sets the new standard for accuracy (0.024% of reading) in the graphical power analyzer market. It integrates an ultra-high accuracy, wideband waveform digitizer with advanced computational capability, a large high-resolution display and a full-color touchscreen user interface.
Rich document chemical/x-pdb Tridonic and NMB-Minebea-GmbH Sign Partnership Agreement
Tridonic, a world-leading supplier of lighting technology, and NMB-Minebea-GmbH, which is part of the MinebeaMitsumi group, the major producer of machinery components and electronics devices, have signed a contract to form a strategic partnership. The partnership aims to develop intelligent outdoor lighting solutions for Smart Cities.
Rich document Luminus Salud™ LEDs Suppress Melatonin and Deliver Warm, Comfortable Illumination
Luminus Devices expands its illumination portfolio today with the introduction of the Salud line of 3030 mid-power LEDs. Salud LEDs are the first with datasheet specified melanopic ratios (MRs) in addition to CRI, R9, CCT, and Flux. By enhancing the spectrum with cyan for melatonin suppression and enriching the 660 nm emission for natural skin tones and excellent red-rendering, Luminus Salud LEDs can deliver warmer, more comfortable light that keeps people healthy, alert, and productive.
Rich document Chinese Researchers Propose Method to Overcome Low Efficiency of High-Power Flip-Chip LEDs
Chinese scientists from different research centers recently published a co-authored paper on "Highly Efficient GaN-based High-Power Flip-Chip LEDs" in Optics Express Vol. 27, Issue 12, pp. A669-A692 (2019)under the terms of the OSA Open Access Publishing Agreement. High-power flip-chip light-emitting diodes (FCLEDs) suffer from low efficiencies because of poor p-type reflective ohmic contact and severe current crowding, they propose an improvement by using an Ag film.

Rich document New CIE Technical Report: Optical Measurement of LED Modules and Light Engines
LED modules and light engines represent a wide range of very different products with unique physical properties. Thus, they can neither be treated as single LED packages (where measurements refer to a specific junction temperature of a single LED or the average of a single die, multiple-junction LED) nor as complete lamps or luminaires (where measurements refer to the ambient temperature).
