GE launches landmark LED modules
The Zhaga compliant Infusion LED devices are a significant step in achieving interchangeability
GE Lighting says it has made a significant breakthrough in the move toward greater standardisation of LED light engines with the announcement of its first Zhaga-compliant products.
GE Lighting’s full range of Infusion LED modules will be showcased at Light+Building, one of the world’s largest trade fairs for lighting and intelligent buildings.
The modules have being designed to comply with the Zhaga ‘Book 5’ specification for Socketable Light Engines with Separate Electronic Control Gear. The Zhaga Consortium creates specifications aimed at ensuring the interchangeability of LED light sources from different manufacturers.
“These specifications are the path forward for LED modules and fixtures that can truly transform the way we light commercial and residential spaces,” says John Strainic, global product general manager, GE Lighting. “Lighting designers and specification professionals around the world now have more freedom to think big because GE and the industry have progressed toward standards established by the Zhaga Consortium.”
GE Lighting is also extending the range with the introduction of four new LED module products: a module for downlight applications, a modular system for creating high-intensity narrow beams, a new format spotlight engine based on Zhaga specification in ‘Book 3’, and a high lumen option. All have been designed with new interchangeable light engine specifications recently approved by the Zhaga Consortium.
In addition to the extended Infusion LED module range, GE Lighting also will launch its range of Lumination LED Downlights, new state-of-the-art luminaires, which will embody Infusion modules.
GE Lighting has been a member of the Zhaga Consortium--a global consortium of companies from the lighting industry and beyond, since the consortium’s establishment in February 2010. In view of the rapid and sustained development of LED technology, the Zhaga Consortium focuses on the mechanical, photometric, thermal and electrical compatibility of LED modules and controls.
More than 180 companies from Asia, Europe and the USA have already joined the Zhaga Consortium. They include luminaire and lamp manufacturers, LED module makers and companies that supply the lighting industry.
“Modularity and interchangeability will benefit manufacturers and end users alike,” explains Andy Davies, sales development director for LED modules, GE Lighting. “The adoption of Zhaga specifications will speed product introduction, and reduce risk and development cost, while still encouraging design innovation. The further we travel down this path, the more accessible LEDs will become.”
Davies adds, “The launch of our Zhaga-compliant Infusion(TM) modules, and the other product developments that will be introduced at Light+Building, represent a significant milestone on the road to interchangeability,”
Osram Opto unveils first
chip-on-board LED The Soleriq E nitride LED for downlights can cope with requirements demanding high lumen packages between 1500 and 4500 lm
Downlights provide high-quality background lighting in shopping malls, offices, industrial buildings and high-end residential premises.
The luminaires used in these places need a high luminous flux to make you feel comfortable. Osram Opto says this is just what its new Soleriq series , claimed to incorporate the first chip-on- board LED, provides. Even at high application temperatures they create the basis for highly efficient luminaires with a luminous flux of 1500 lm to 4500 lm.
