OSRAM SYLVANIA’s vision for <strong>LED</strong> light<strong>in</strong>g<br />

OSRAM SYLVANIA is committed to develop and promote<br />

environmentally friendly and energy efficient light<strong>in</strong>g systems.<br />

<strong>LED</strong> systems for <strong>general</strong> light<strong>in</strong>g, display backlight<strong>in</strong>g and automotive<br />

headlamps reflect our current focus on commercializ<strong>in</strong>g this technology.<br />

We believe <strong>in</strong> us<strong>in</strong>g light<strong>in</strong>g technology to offer products that are useful,<br />

create new <strong>applications</strong> and are fun to use<br />

“We make better light for better liv<strong>in</strong>g”

<strong>LED</strong> Standards<br />

• Several standards sett<strong>in</strong>g bodies work<strong>in</strong>g on<br />

creat<strong>in</strong>g standards for def<strong>in</strong>itions,<br />

measurement, performance and safety of <strong>LED</strong><br />

based light<strong>in</strong>g systems<br />

• Still a work-<strong>in</strong>-process but several advances<br />

have been made<br />

• US DOE act<strong>in</strong>g as a facilitator and a good<br />

source for <strong>in</strong>formation on the various<br />

standards


<strong>LED</strong> Standards<br />

Some key standards (not a comprehensive list)<br />

• ANSI C78-377-2008, Specification for the Chromaticity of Solid-State Light<strong>in</strong>g<br />

Products<br />

• IESNA LM-79, Approved Method for the Electrical and Photometrics Test<strong>in</strong>g<br />

of Solid-State Light<strong>in</strong>g Devices<br />

• FCC 47 CFR Part 15, EMI requirements for SSL power supplies and<br />

electronic drivers<br />

• IESNA RP – 16 Def<strong>in</strong>itions (<strong>in</strong> process)<br />

• IESNA LM – 80 Lifetime (<strong>in</strong> process)<br />

• ANSI C82-XX1 Power Supply (<strong>in</strong> process)<br />

• Objective:<br />

– The color render<strong>in</strong>g <strong>in</strong>dex (CRI) has been<br />

used to compare fluorescent and HID lamps<br />

for over 40 years, but the International<br />

Commission on Illum<strong>in</strong>ation (CIE) does not<br />

recommend its use with white light <strong>LED</strong>s. A<br />

new metric is under development. In the<br />

meantime how should we use CRI when it<br />

comes to <strong>LED</strong>s?

Conclusion<br />

•<strong>LED</strong>s have already started enter<strong>in</strong>g the <strong>general</strong> light<strong>in</strong>g<br />

market as well as created new light<strong>in</strong>g <strong>applications</strong><br />

»Initial market penetration has been <strong>in</strong> specific application<br />

segments - signage, architectural light<strong>in</strong>g, down light<strong>in</strong>g, cove<br />

light<strong>in</strong>g, streetlight<strong>in</strong>g, undercab<strong>in</strong>et, shelf light<strong>in</strong>g, display/freezer<br />

cases<br />

»<strong>LED</strong>s will evolve to become one of the ma<strong>in</strong>stream light<strong>in</strong>g<br />

technologies<br />

»<strong>LED</strong>s have to overcome “quality of light” performance barriers to<br />

deliver on customer expectations<br />

»Several alternative bus<strong>in</strong>ess models are evolv<strong>in</strong>g but it’s too early<br />

to tell which ones will be successful <strong>in</strong> the long run<br />
