OSRAM Opto Semiconductors showcased a host of new LED illumination solutions at the 2008 Strategies In Light conference and exhibition. On display were working demos of OSRAM’s new Diamond DRAGON® LED and the Advanced Power-Saver® technologies from mSilica Inc., combining high level functionality and high efficiencies with reduced component count.OSRAM’s newly launched Diamond DRAGON is one of the world’s brightest single-chip SMT LEDs (up to 250 lumens) with exceptionally low thermal resistance for general, automotive and industrial lighting applications.  The Diamond Dragon can be driven at 2 amp continuous or 4 amp pulsed which requires a new class of LED drivers, several of which will be on display at the show.

Joint Reference Designs with LED Drivers

Showcase Advanced LED Subsystems for General Lighting & LED Backlighting

Santa Clara, CA (February 11, 2008) – OSRAM Opto Semiconductors will showcase a host of new LED illumination solutions at the 2008 Strategies In Light conference and exhibition, February 11-13,  at the Santa Clara Convention Center, Booth 206. On display will be numerous working demos of OSRAM’s new Diamond DRAGON® LED and the Advanced Power TopLED® technologies with market ready reference design drive circuitry from Linear Technology, National Semiconductor, and mSilica Inc  combining high level of functionality and facilitating low component count.

OSRAM’s newly launched Diamond DRAGON is one of the world’s brightest single-chip SMT LEDs (up to 250 lumens) with exceptionally low thermal resistance for general, automotive and industrial lighting applications.  The Diamond Dragon can be driven at 2 amp continuous or 4 amp pulsed which requires a new class of LED drivers, several of which will be on display at the show.

Working demos of the  Diamond DRAGON powered by Linear Technologies’ LT3518, a full featured LED driver with a 2.3A current, 45V internal switch that provides a 3000:1 True Color PWM dimming ratio, open LED protection, and a wide input voltage range,  providing stable operation and suitable for automotive and general lighting applications.

A second Diamond DRAGON LED demo powered by National Semiconductor’s NS LM3401 PFET controller driver that can run at up to 100% of duty cycle, which maximizes the number of LEDs being driven off an input rail will also be on display. The LM 3401 also enables very flexible system design and reduces component count as it does not require an output capacitor or compensation.

Also in operation will be a new 2-dimensional backlight demo designed with 160 RGB Advanced Power TopLEDs® driven by mSilica’s MSL3082 8-channel LED Driver on a companion LED load board.  The mSilica driver incorporates Adaptive SourcePower™ technology to control DC-DC power supplies with optimal efficiency, complementing the Advanced Power TopLED’s outstanding performance capabilities for general lighting, LCD TV and monitor backlighting.
