AVX has added a locking plug to its 70-9159 series of low-profile 5A board to board connectors. Part of its ‘Stript’ insulator-less single contact range, the gold-plated beryllium-copper (BeCu) spring contacts have a positive latching mechanism and can absorb a 1mm of tolerance in the x and y direction. Led lighting is one intended application – the locking plug features the same ...

The Lighting Research Center of Rensselaer Polytechnic Institute is questioning some of the findings in a report on LED street lighting from the American Medical Association (AMA) – which advocates LED lighting, but urges caution on luminaire selection. See also: Cree talks LED streetlamps. Last month, physicians at the AMA annual meeting adopted guidance on how street lighting planners should select ...

Power Integrations has introduced a one-chip non-isolated LED driver for loads up to 22W. Capable of working from inputs from 90 to 305Vac, it is triac (and trailing-edge) dimmable on nominal 110V supplies, but not on 230V supplies. The dimming voltage is a clue here – this chip is aimed at commercial US installations where mains is split-phase and either 110V ...

The University of South Wales (USW) and the Lighting Industry Association (LIA) have announced a formal partnership, which will see the development of a range of specialist lighting courses.

Researchers from KU Leuven (Belgium), the University of Strasbourg, and CNRS have discovered a new phosphor that could make next-generation fluorescent and LED lighting even cheaper and more efficient. The team used highly luminescent clusters of silver atoms and the porous framework of minerals known as zeolites. Silver clusters consist of just a few silver atoms and have remarkable optical ...

This month Infineon starts volume production of an LED lighting interface IC which allows designers to replace many of the discrete components used in conventional dimming schemes with a single device. Thus, it can reduce the component count and PCB space needed for dimming circuitry in LED lighting applications by up to 70%. Infineon claims its CDM10V is the industry’s ...

The whys and wherefores of AC-direct driving of LED lighting systems explained by Francois Mirand True to the history of other types of semiconductor products, LEDs offer better performance at a lower cost with every passing year. So much so, in fact, that the other elements of a conventional LED lighting fixture – the housing, connectors, PCB, optics, and most ...

Cree has further up-graded its XP-G lighting LED, to version 3. XP-G3 delivers 31% more lumens and 8% higher lm/W that the XP-G2. “XP-G3 LED improves the lumen density, voltage characteristics and reliability of previous XP-G generations,” said Cree, claiming over 205 lm/W at 350mA and up to 863 lm at 2A will be available from the 3.45 x 3.45mm ...

Taiwan’s Industrial Technology Research Organization (ITRI) is building a flexible OLED lighting panel production line capable of producing 700 panels a month, reports Digitimes. Production on the roll-to-roll line is scheduled to start next year. The panels are made using thin film glass substrates. A 7cm by 7cm OLED lighting panel with luminous efficiency of 70-80lm/W will initially cost about ...

Plessey believes it is time to grow plants under artificial LED lighting. The UK-based LED lighting technology company has signed a license agreement to manufacture and sell horticultural lighting systems developed by PhytoLux. Plessey has also taken on the operational, technical and commercial activities of PhytoLux and said it wants to provide LED plant growth lighting solutions for the global ...
