Epistar & Intermolecular collaborate with LED IP licensing
The companies will work together to accelerating R&D of new materials and manufacturing processes for LEDs using Intermolecular’s technology
Intermolecular and Epistar have signed a collaborative development program (CDP) and royalty-bearing IP licensing agreement to increase the efficiency and reduce cost of Epistar’s LED devices.
Under this agreement, Epistar and Intermolecular engineers will try to leverage Intermolecular’s High Productivity Combinatorial (HPC) technology platform to dramatically accelerate development and manufacturing qualification of novel materials and processes for advanced LED products.
“After a rigorous review of Intermolecular’s capabilities through an initial collaboration engagement, we have seen how their combinatorial approach to materials innovation and device integration can augment Epistar’s leadership in LED technology,” says M. J. Jou, president of Epistar. “Collaboration with our industry partners has been critical to our world-leading R&D and manufacturing strategy. We are confident that leveraging Intermolecular’s team and technology platform will further increase our competitive advantage.”
The commercial LED market is highly competitive, and new technologies created by R&D are needed to both improve light output and to reduce costs. A multi-functional team of technologists from Epistar and Intermolecular will work together using the HPC Platform to accelerate the pace of R&D ten times or more compared to what can be achieved in a conventional LED lab.
“We are very excited to partner with Epistar, a global leader in LED manufacturing,” comments Sandeep Nijhawan, senior vice president and general manager of Intermolecular’s clean energy group. “Entering into a strategic engagement with a top-tier LED company like Epistar validates the applicability and disruptive potential of the HPC technology platform for LEDs, a market that continues to have tremendous room for growth and technology innovation.”
Intermolecular’s mission is to improve R&D efficiency in
the semiconductor and clean energy industries through collaborations that use its HPC platform, which allows R&D experimentation to be performed at speeds up to 100 times faster than traditional methods.
Osram unveils five new colour versions for LED Duris P 5
The company has revealed new design options with indium gallium nitride and indium gallium aluminium phosphide mid-power LEDs
Osram Opto Semiconductors now offers the mid-power LED Duris P 5 in colour.
The five new versions have impressively high luminous efficacy from a compact form factor, already known from the white version. The LEDs are ideal for architecture lighting and for the hospitality sector, in other words hotels and restaurants.
The five colour versions of Duris P 5 are “deep blue” (450 nm), “blue” (470 nm), “true green” (528 nm), “yellow” (590 nm) and “red” (615 to 625 nm).
At the heart of the different colours are state-of-the- art chip technologies from Osram, based on either the InGaN material system or InGaAlP depending on the wavelength.

Low forward voltages and optimised light extraction result in high luminous efficacies for all types. The “deep blue” version, for example, delivers a light output of 140 mW (at 100 mA and 250C), corresponding to a typical efficiency of 48 percent. Efficiency is defined as the ratio of the amount of light produced to the amount of power consumed.
As members of the mid-power class, the colour versions of Duris P 5 are ideal for linear, area or omnidirectional lighting applications in which the light has to be
