Marvell and Osram Opto Semiconductors today announced the availability of the Marvell-Osram two-color LED downlight reference design to further facilitate mass market adoption of high-quality, affordable LED lighting. The turnkey reference design, based on high performance LEDs from Osram and highly integrated and advanced driver ICs from Marvell, drastically reduces the engineering complexity involved in designing and manufacturing premium performance, high- color rendering index (CRI) LED luminaries for professional and commercial lighting applications. This is expected to enable lighting original equipment manufacturers (OEMs) to easily develop and offer significantly higher quality LED products at more affordable prices to end users. The reference design will be shown at LIGHTFAIR International 2012 from May 9 – 11 in Las Vegas.
This turnkey reference design, based on Osram’s Brilliant Mix LEDs and the Marvell® 88EM8801 LED driver IC, offers an unparalleled solution for mixing and controlling the EQ-white and amber LEDs to achieve higher CRI and lumens per watt. Marvell’s 88EM8801 LED driver IC integrates circuitry for two-channel drive electronics and various on-chip digital controls, addressing complex design challenges commonly faced by OEMs, and lowering the overall bill of materials (BOM).
“With standard LEDs, current color mixing technologies make it impossible to realize a LED luminaire with both high efficiency and high CRI. EQ-white and amber LEDs have different luminous flux behavior causing complex operating temperature design challenges,” said Joerg Schmidt, marketing manager with Osram Opto Semiconductors. “Joining forces with Marvell was instrumental in furthering Osram Opto Semiconductors’ deployment of high-quality, low-cost LEDs for mass market commercial and residential lighting. Leveraging Marvell’s innovative LED IC driver and Osram’s Brilliant Mix technology, OEMs can easily build a feedback controlled system for temperature drift compensation to enable brilliant color, high performance and energy efficient lighting.”
“Our collaboration with Osram Opto Semiconductors validates Marvell’s continued commitment to providing innovative, high-performance and low-cost LED driver solutions that further the mass market adoption of environmentally friendly, quality lighting,” said Lance Zheng, senior technical marketing manager for the Green Technology Products Group at Marvell Semiconductor, Inc. “Building on Marvell’s dual-string smart LED driver controller and single chip ZigBee microcontroller, the Marvell-Osram two-color downlight reference design brings us one step closer to the widespread implementation of LED lighting. With this reference design, we anticipate manufacturers should be able to quickly produce LED lamps and fixtures with superior light quality with integrated control that not only meets, but often exceeds consumers’ performance needs.”
Reference Design Details
The Marvell-Osram two-color LED downlight reference design uses the Marvell dual-string intelligent LED driver IC 88EM8801 and the Marvell microcontroller System-on-a-Chip (SoC) 88MZ100. The 88EM8801 is the industry’s first dual-string smart LED controller chip, which uses the company’s unique mixed-signal power technology to enable superior lighting performance while maintaining high-levels of integration and efficiency. The 88MZ100 microcontroller is the industry’s first SoC with the highest level of integrated features for both ZigBee and DALI standards as well as custom lighting applications. Leveraging Osram’s Brilliant-Mix LED mixing concept, the reference design achieves CRI of greater than 90; efficacy is 30 percent higher than other mass market LEDs; and an innovative temperature compensation feature overcomes color point shift issues.
