Double color LED lamp reference design Marvell and OSRAM jointly launched

The global integrated chip solutions leader Marvell Technology (MarvELl, Nasdaq:, MRVL) and OSRAM (Osram Opto Semiconductors) semiconductor photoelectric company recently announced the launch of OSRAM Marvell- dual color LED lamp reference design, LED lighting applications in order to further promote the mass market with high quality, affordable. This turnkey type OSRAM reference design for high performance LED and Marvell highly integrated, advanced driver based on IC, in the professional and commercial lighting applications require high performance and high color index (CRI) of LED lighting, the reference design can greatly reduce the complexity of the project, the LED lamp lighting equipment the manufacturer is expected to facilitate the development of higher quality, and to provide more affordable price to the end user.

The design of this turnkey reference using the OSRAM Brilliant Mix LED and Marvell 88EM8801 LED driver IC, provides a solution for the incomparable color mixing and control EQ- white and amber light LED, can achieve higher luminous efficiency and color rendering index. 88EM8801 LED driver IC Marvell integrates dual drive circuit and various built-in digital control function, can cope with the challenges of complex design equipment manufacturers often face, and reduce the cost of bom.

If the standard LED is used, the current hybrid technology is unlikely to achieve a high efficiency and high color rendering index of LED lighting, according to Joerg Schmidt, a marketing manager at OSRAM semiconductor corporation. EQ- white light and amber light LED flux characteristics are different, resulting in a complex design challenges related to working temperature. Marvell cooperation is of great significance, can promote our commercial and residential lighting and other mass market to provide high quality, low price LED. With innovative LED IC driver Marvell and our Brilliant Mix technology, equipment manufacturers can easily develop a feedback control system to compensate for temperature drift, to achieve high performance and energy-saving bright color and lighting applications. "

Marvell green technology products division, senior technical marketing manager Lance Zheng said: "with OSRAM Opto Semiconductors cooperation that we have been committed to providing innovative, high performance and low cost LED drive solutions, to promote high quality lighting and environmental protection by the mass market. OSRAM Marvell- dual color downlight reference design Marvell double LED series intelligent drive controller and single chip micro controller ZigBee as the foundation, make us toward the goal of popularization of LED lighting and a step forward. We expect that with this reference design, manufacturers will be able to LED the rapid production of lighting facilities with excellent lighting quality and integrated control ability, so the lighting facilities can not only meet and often exceed the performance requirements of consumers. "

Reference design details

Marvell- OSRAM dual color LED under the light of the reference design using the Marvell dual string intelligent LED driver IC 88EM8801 and Marvell single chip system (SoC) microcontroller 88MZ100. 88EM8801 is the industry's first dual intelligent LED controller chip, using a unique hybrid Marvell signal power supply technology, can achieve superior lighting performance, while maintaining high integration and high efficiency. 88MZ100 microcontroller is the industry's first functional integration of the highest SoC, support ZigBee and DALI standard and custom lighting applications. With the OSRAM Brilliant-Mix LED color mixing technology, the reference design of CRI higher than 90, the mass market efficiency than other LED 30%, and its innovative temperature compensation function to solve the problem of color point drift.
