SEMI's LED Standards Committee HB-LED Standard Published
After the formation of the high-brightness light-emitting diode (HB-LED) Standards Committee in November 2010 the committee was working hard on HB standards. The committee is happy to announce that it now has approved its first standard, SEMI HB1: Specifications for Sapphire Wafers Intended for Use for Manufacturing High Brightness-Light Emitting Diode Devices. Developed by the HB-LED Wafer Task Force, SEMI HB1 defines and specifies the physical geometry of 150 mm diameter sapphire wafers used in HB-LED manufacturing. HB1 covers dimensional, wafer preparation, and crystallographic orientation characteristics, as well as the appropriate measurement methods. The document was approved by the HB-LED Committee during the North America Fall 2012 meetings, recently completed procedural review and will be published soon. Read more »

Standardization of Performance Criteria for LED Luminaires
This guiding paper is intended to help bring clarity by introducing a universal set of quality criteria that are recently described in two IEC/PAS documents. As a user of LED luminaires it is important to apply the same set of standardised and therefore comparable quality criteria when evaluating manufacturer’s claims. Users of LED luminaires should always ask for LED luminaire specifications measured in compliance with the new IEC/PAS documents. Read more »

Visual Appearance: Perception, Measurement and Metrics
Visual Appearance: Perception, Measurement and Metrics Visual appearance is one of the most critical parameters affecting customer choice and needs in products. We use the response from our visual sense to process the complex patterns of light around us into objects, space, location and movement, and from that information, we make judgments leading to a particular course of action. For example, how we perceive the visual appearance of a product may cause us to buy it, reject it or even write to complain about it. We may choose to buy a particular food because its appearance suggests freshness. Our choice of car may have been influenced because its glossy appearance made us think of quality and prestige. Alternatively, we may reject a particular surface finish because its appearance suggested poor quality and the presence of defects. All of these examples represent judgments made on appearance.
