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.

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.

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.

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.

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).
