FDG SERIES LENSES for OSRAM GOLDEN DRAGONTM LEDs High efficiency Available in 4 different beams Patent pending The FDG Series offers a complete range of lenses especially designed for the Golden Dragon (1) LEDs from Osram Optosemiconductor. A software-optimized aspheric profile combined with front shaped micro-lens arrays enable the generation of four different lens models: narrow beam, medium beam, wide beam, and elliptical pattern (2). TM (1) Golden Dragon is a trademark of Osram Optosemiconductor. For technical specifications on the LEDs please refer to the Golden Dragon datasheet or visit www.osram-os.com (2) Typical beam divergence may change with different color LEDs. The high collection efficiency reaches 85% of the total flux emitted by the LEDs. Lens holders are available either in white PC/ABS or transparent PC, and provide the proper alignment between the LEDs and For ordering instructions, please contact the lenses. If a holder is not used, a special spacer ring must be used to assure proper FRAEN CORPORATION FRAEN Srl alignment. Scott M. Grzenda Dimitri De Gaetano 80 Newcrossing Road Via E.

Please note that flow lines and weld lines on the external surfaces of the lenses are acceptable if the optical performance of the lens is within the specification described in the section "OPTICAL CHARACTERISTICS" IMPORTANT NOTE - Lenses handling and cleaning: Handling: Always use gloves to handle lenses and/or handle the lenses only by the flange. Never touch the outside surfaces of the lenses with fingers; finger oils and contamination will absorb or refract light. Cleaning: Clean lenses only if necessary. Use only soap and water to clean the surfaces and lenses. Never expose the lenses to alcohol, as it will damage the plastic. _______________________________________________________________________ 10/08/2006 2/9 FDG series lenses Optical Characteristics: ____________________________________________________________ Typical beam total divergence (degrees) Lens Part Number FDG-N1-D01-xx FDG-M1-D01-xx FDG-W1-D01-xx Type of lens Narrow beam Medium beam Wide beam Blue / Green Dragon Yellow / Red Dragon ThinGaN ThinFilm NOTA LxW5SG LxW5SF 6.0 White Dragon LWW5SG Volume casting ZWW5SG Chip coating LWW5SG 6.0 9.0 7.0 6.5 21.0 21.0 22.0 21.0 20.5 34.5 35.0 32.0 33.5 33.5 11.0 * 19.5 10.0 * 19.5 13.0 * 20.0 13.0 * 20.0 10.0 * 20.0 Elliptical beam The typical divergence varies with LED color due to different chip size and chip position tolerance.

Please note that the above measurements have been taken with Dragon LEDs powered at 100mA. The efficiency can vary with the current driving the LEDs.

To achieve correct lens position on the LED, the lens must be used either a holder, or spacer ring.
