Chinese Researchers Propose Method to Overcome Low Efficiency of High-Power Flip-Chip LEDs
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
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).

WHITE PAPER - Measuring Color Uniformity
WHITE PAPER - Measuring Color Uniformity The color uniformity of light generated by LED luminaires plays a major role in many lighting applications. This makes it an important parameter to measure in both the R&D stage and during the quality assurance process. MKS Instruments has stayed abreast of this challenge by developing a new feature for its FluxGage photometrical system: the color uniformity measurement function. It allows quick evaluation of optical assemblies for color mixing and beam shaping. This whitepaper presents this novel feature of the system. Read more »

Study Reveals How Age Affects Perception of White LED Light
Study Reveals How Age Affects Perception of White LED Light Although LEDs are increasingly used in low-energy lighting and displays, consumers sometimes find their light harsh or unpleasant. Findings from a new study point to the need to take age-related perception differences into account when designing white LED lighting that is more pleasing to the eye. Read more »
