High Performance Diffusers For LED and Fluorescent Luminaires Bright View Technologies’ high performance diffusers are based on a proprietary technology platform that combines advanced microstructures with versatile substrate options and form factors. Bright View diffusers provide industryͲleading performance in terms of angle control, efficiency, source hiding, and aesthetics. Efficiency Bright View diffusers enable high efficiency extraction of light from a luminaire without sacrificing performance. Transmission well in excess of 90% is typical, and luminaire dependent efficiency can be even higher. Bulb Hiding & Homogenization Bright View diffusers offer outstanding hiding of LED and fluorescent light sources, with excellent color mixing. Bright View diffusers solve the most difficult LEDͲhiding problems while maintaining industryͲ leading efficiency. Light Management Bright View provides a full range of diffusion strengths (i.e. beam angles) for management of luminaire light distributions and glare control. This includes flatͲfield (“batwing”), symmetric, asymmetric, and elliptical light distributions. Widerangeofavailableangles NarrowMixing Standard Bilateral(flatͲfield) Elliptical AngleBend Aesthetics Bright View PͲSeries patterned diffusers offer groundbreaking aesthetics without sacrificing exceptional light management performance and provide limitless customized solutions for luminaire designers. New Glare Control Diffusers Bright View Technologies announces patentͲpending glare control diffusers that combine strong suppression of light above 65° from vertical with a smooth cutoff and an unprecedented level of diffusion. By combining glare control, diffusion, high efficiency, suppressed color fringing, and aesthetics, the new Bright View GͲSeries Glare Control diffusers offer unique advantages for highͲ performance luminaires. 1 sales@brightviewtech.com +1Ͳ919Ͳ228Ͳ4370 www.brightviewtechnologies.com Product Overview Bright View High Performance Diffusers Products Diffuser Strength (highernumbersare more diffusive) Efficiency in typical luminaire Comment GeneralͲpurpose (symmetric) diffusers 15Ͳ 85 87Ͳ 96% General purposeforsmoothing,lamphiding, andcolormixingondownlights,troffers, linear,specialty EͲSeries Ellipticaldiffusers 60x10 60x20 91Ͳ 95% Spreadslightelliptically.MixeslinesofLEDs, andhomogenizesfluorescentlamps.Also excellentforwallwash,cove,linear,specialty GͲSeries Glare control 65° cutoff 89Ͳ 93% Suppresseslight above65degreestoreduce glare MͲSeries NarrowͲangle diffusers 5Ͳ 15 91Ͳ 95% BeamMixing fornarrowPAR,spot,flood,and downlights AͲSeries Anglebending 20x60 88Ͳ 92% Upto20degreesbendwithcrosswise spreadingforwallwash,cove,specialty PͲSeries Patterned diffusers Product Line Description CͲSeries PatternsmaybecombinedwithCͲSeries,EͲSeries, GͲSeries,etc.tocreatea uniqueaestheticlookwhilemaintainingopticalperformanceofthebasediffuser BrightView Technologiesmaintainsapipelineofnewproductofferingsandprovidescustomdesignservicesuponrequest Material and Thickness Options Bright View diffusers are offered on a variety of materials and thicknesses.

They are used to diffuse a line of LEDs into a smooth line, or to blend adjacent fluorescent lamps. They are also used to provide optimum spreading in wallͲwash and cove applications. Because diffusion is only applied along one direction, efficiency is even higher than CͲSeries diffusers. Bright View’s unique design causes less scalloping than competitive approaches, giving a smoother visual result.

Their unique design provides superior farͲfield smoothing and color mixing with high onͲaxis brightness. Unlike traditional diffusers, there is minimal decrease in central intensity, and minimal increase in offͲtask “field light.” Note: MͲSeries diffusers do not have focusing power Ͳ they are designed for use in conjunction with parabolic, Fresnel, TIR, or other collimation optics.
