FDP SERIES LENSES For OSRAM GOLDEN DRAGON LEDs High ...

<strong>FDP</strong> <strong>SERIES</strong> <strong>LENSES</strong><br />

<strong>For</strong> <strong>OSRAM</strong> <strong>GOLDEN</strong> <strong>DRAGON</strong> <strong>LEDs</strong><br />

� <strong>High</strong> efficiency<br />

� Available in 2 different beams<br />

� Patent pending<br />

The FDG Series offer low-profile lenses<br />

especially designed for the Golden Dragon (1)<br />

<strong>LEDs</strong> from Osram Optosemiconductor.<br />

A software-optimized aspheric profile combined<br />

with front shaped micro-lens arrays enables the<br />

generation narrow beam and medium beam<br />

output patterns (2).<br />

The high collection efficiency reaches 85% of<br />

the total flux emitted by the <strong>LEDs</strong>.<br />

Lens holders are available either in white<br />

PC/ABS or transparent PC, and provide the<br />

proper alignment between the <strong>LEDs</strong> and the<br />

lenses.<br />

Heat staking the four legs of the holder to the<br />

customer’s PCB or heat sink provides excellent<br />

optical and mechanical assembly (see Fraen<br />

Application Note FAN01-EN (at<br />

www.fraen.com).<br />

Typical applications are:<br />

• Reading lamps<br />

• Signs<br />

• Architectural Lighting<br />

• Street Lights<br />

(1) Golden Dragon is a trademark of Osram<br />

OptoSemiconductor. <strong>For</strong> technical specification on<br />

<strong>LEDs</strong> please refer to the Golden dragon datasheet<br />

or visit www.osram-os.com<br />

(2) Typical beam divergence may change with different<br />

color <strong>LEDs</strong>.<br />

The typical total divergence is the full angle measured where the luminous intensity is half of the peak value.<br />

The typical divergence may change with different color <strong>LEDs</strong> due to different chip size and chip position<br />

tolerance.<br />

To calculate the on axis intensity, multiply the on axis efficiency of the lens (cd/lm) by the total flux of the<br />

Dragon <strong>LEDs</strong> you use. <strong>For</strong> more detail on flux binning please check the datasheet of the Golden Dragon<br />

<strong>LEDs</strong> by Osram OS.

Mechanical Characteristics<br />

________________________________________________________________<br />

In order to get the best optical performances showed above, you need to have the exact<br />

mechanical position of the lens on the Dragon LED.<br />

In order to do so, you need to use the lens you need (Narrow, Medium) with its holder.<br />

Please note that flow lines and weld lines on the external surfaces of the lenses are<br />

acceptable if the optical performance of the lens is within the specification described in the<br />

section “OPTICAL CHARACTERISTS”.<br />
