Better Light, Better Image HPA Technology Retreat 2012 Laser Engines for Digital Cinema Have we checked all the boxes? Bill Beck Co-founder; EVP bbeck@laserlightengines. com Salem, NH
Laser Light Engines – at a glance Better Light, Better Image • LLE is a VC backed start-up in Salem, NH • Multi-disciplinary; systems oriented; image quality and IP-centric • Vision: create a new category of solid-state illumination Laser-driven, no-speckle, fiber-coupled RED/GREEN/BLUE (RGB) light • Mission: develop and sell RGB laser light “engines” to performance projection markets, including D-Cinema • Strategy: universal modules and engines for retrofit and new designs • Core competencies: systems approach; laser design; despeckling; projector interface; fiber delivery
Better Light, Better Image Requirements drive demand… AND THE RIGHT TECHNOLOGY
Better Light, Better Image Critical Requirements Full brightness 3 D • • Constant >11 f. L; 60 - 200 klm…pre-3 D cut No speckle on silver or white high gain screens for all types of content Retrofit installed base • • >50% of screens converted; most with new projectors Universal engines will drive high production volumes Better image quality • • Complete despeckling (SCR% = Xenon) Increased contrast ratio (>5000: 1) and bit depth (>10) Reduced Total Cost of Ownership (TCO) • Lower OPEX must pay back first cost of retrofit engines
Better Light, Better Image LLE Technology… EXCEEDS THESE REQUIREMENTS
Better Light, Better Image Full Brightness 3 D • High output, low étendue modules and engines – Key to power scaling and efficient fiber delivery (retrofit) • Optimum primaries maximize lm/laser watt (>300) • Maximum lm/W minimizes projector thermal load • Despeckled RED/GREEN primaries work in 3 D – Silver and white, high gain screens
Better Light, Better Image Retrofit Installed Base • Interfaces demonstrated for all major Cinema and performance projection designs • Small, flexible fiberoptic cables connect engine to projector – Single White; single RGB or multi-RGB bundles – Pedestal, Booth Rack or Server Closet options – 2 -100 meter remote delivery demonstrated • Universal, stackable engines drive volume manufacturing – Simplifies engine design; reduces cost – Provisioning and sparing more flexible and economical
Better Light, Better Image Quality • Complete 2 D and 3 D despeckling in side by side tests vs. Xenon – – All types of content All types of screens All types of projectors All major 3 D systems live or animation / motion or still silver or white / high gain or unity gain DLP® and LCOS / D-Cinema and non-cinema Polarization / Spectral • SCR% = to Xenon out of the laser; no projector modifications required – Key is massive spectral broadening – NOT large numbers of discrete narrowband lasers • Spectrally broadened primaries enable despeckling; high f# and contrast • Low étendue, pulsed lasers enable >5000: 1 contrast; greater bit depth
Keys to lower TCO Better Light, Better Image • Low acquisition cost – Universal retrofit design drives highest production volumes – Highest efficacy primaries reduces required laser watts and cooling – Use of mature, lowest $/W pump and BLUE diodes • Long lifetime – Use of longest lifetime pump and BLUE diodes will enable >30, 000 hour lifetime • Reduced light engine and HVAC power consumption • Figure of merit is: $ / klm-hour – 6 k. W Xenon - $0. 14 /klm-hr (does not include original lamp/lamp house Bo. M) – Retrofit Laser Engine - $0. 07/klm-hr (Lower for integrated engine)
Remaining Challenges ü ü q q Better Light, Better Image Power Scaling for Brighter 3 D Complete despeckling on white and silver high gain screens Universal fiber-based retrofit designs Hollywood ready image quality Simplified regulatory requirements (LIPA focus) Manufacturing scale-up and cost reduction LLE has checked all the technology boxes – even knocked the 3 D speckle curveball out of the park… …now it’s time to build and ship some laser light engines
