LEDs ♦ news digest
The three-year project, known as MODULED, will industrialise smart LED systems in France by simplifying functioning and assembly, reducing the mechanics and electronics of current LED systems, and incorporating the latest LED features. The project also will include establishing processes to allow the fabrication of next-generation LED modules while reducing the costs of acquisition for OEMs.
”The next generation of LEDs will react with their environment -- the lighting of the space and the presence of a person -- and the lighting envelope will assure heat dissipation,” said Ludovic Labidurie, CEO of Neolux. “Together, these developments will significantly reduce the cost of these products, and our project will take advantage of these changes to develop a new generation of intelligent LED systems.”
Leti has focused on LED lighting technology since 2006 and in recent years has launched a variety of projects to deal with the key issues of thermal management, light extraction and wavelength conversion.
“LEDs offer unparalleled possibilities to integrate new features beyond their energy efficiency,” said Laurent Malier, Leti CEO. “I am convinced that we are at the dawn of a generation of ‘intelligent’ lighting objects that is similar to what we saw happening in communications products 10 years ago. Leti has been preparing for this evolution for several years and the successful integration of our new technologies will allow Neolux to open new markets, while reinforcing its offer against increasingly tough competition.”
The partnership will give Neolux, which conceives and commercialises LED lighting solutions, access to the project’s first qualified product.
Rubicon qualified to supply 6-inch polished sapphire wafers
The firm’s Malaysian plant also aims to produce 8-inch sapphire wafers in volume to cope with increasing demand from the global LED industry.
Rubicon Technology, a provider of sapphire substrates, has two critical milestones that enable its new state-of-the-art facility in Penang, Malaysia to move into volume production of six- and eight- inch polished sapphire wafers.
Rubicon’s new Malaysia facility recently completed qualification of its six-inch wafers by a key customer, and also successfully completed an ISO certification audit. Both of these milestones enable the Malaysian facility to move into volume production of six-inch polished wafers, which are in high demand as LED chip manufacturers continue to migrate to larger diameter substrates to realise greater efficiencies. The facility is also capable of processing and polishing eight-inch wafers that Rubicon provides to customers in R&D volumes.
Rubicon’s customers demand exceptional quality -- consistently delivered -- and often require vendors to achieve and maintain globally recognized quality standards, such as those set by the International Organization for Standardization (ISO). Rubicon’s Malaysia facility recently passed the rigorous audit by ISO inspectors with zero findings and has been recommended for ISO 9001:2008 certification, which is expected to be formally issued upon final review by the registrar.
Most companies in the semi-conductor industry also require vendors to re-qualify products when a new manufacturing facility is opened. Rubicon has been in the re-qualification process with a number of existing customers who have previously purchased six-inch wafers produced in Rubicon’s U.S. facility. The Malaysian facility now has qualified with a major customer. The qualification process involves successful production of LED chips on Rubicon six- inch sapphire wafers and rigorous testing of those chips in various applications.
Rubicon’s custom equipment and manufacturing processes position the company as the leading provider of high quality, large diameter sapphire wafers to manufacturers of LEDs worldwide. Rubicon’s Malaysia facility, combined with its new crystal growth facility in Batavia, IL – both leveraging large-diameter sapphire -- were established to deliver the sapphire capacity necessary to support the growing demand for LEDs in the consumer electronics and general lighting industries.
