PRODUCT NOTE

Elliptical Diffusers E-Series Elliptical (Asymmetric) Diffusers

E-Series elliptical diffusers spread asymmetrically – more strongly in one direction than the other. 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 beam smoothing and spreading in wall-wash, linear, and cove applications. Because diffusion is only applied along one direction, efficiency can be even higher than C-Series diffusers. Bright View’s unique design causes less scalloping than other approaches, giving a smoother visual result.

Usage Notes: • For lamp hiding as pictured above, E-Series diffusers are directional and are generally used with the

microstructures facing away from the LEDs or lamps; please try both orientations • For light spreading in wall-wash and cove applications, E-Series diffusers are generally used with the

microstructures facing toward the LEDs or lamps; please try both orientations • Bright View applications engineers can assist with product choices and help your design achieve peak

Glare Suppression

Gain

G-Series diffusers suppress high-angle light above 65 degrees to reduce visual glare and improve the Unified Glare Rating (UGR) of luminaires. This helps luminaires comply with IESNA RP1-04 and EN12464 glare specifications. These patented2 and patent-pending diffusers, unlike conventional prismatic sheets, have a soft cutoff with no color separation thereby increasing visual appeal and LED hiding ability.

M-Series diffusers are used in spot and narrow flood lighting to smooth beam artifacts caused by parabolic, Fresnel, or TIR lens collimators without significant broadening. The unique mixing design provides superior far-field smoothing and color mixing with high on-axis brightness. Compared with traditional diffusers, M-series diffusers maintain higher central beam candlepower (CBCP), and produce less undesirable “field light” at higher angles.

Usage Notes: • M-Series diffusers may be used in either orientation. Bright View recommends using the microstructures

facing toward the LEDs or lamps • Choose the minimum-strength M-Series diffuser that provides the needed smoothing • M-Series diffusers do not have focusing power – they are designed for use in conjunction with parabolic,

Fresnel, TIR, or other collimation optics • Bright View applications engineers can assist with product choices and help your design achieve peak

A-Series diffusers provide an elegant solution for wall-wash, sign illumination, and specialty applications, providing an angle bend to direct the light toward a wall or surface, combined with a simultaneous cross-wall diffusion, to eliminate scalloping and increase uniformity.

Usage Notes: • A-Series diffusers are generally used with the microstructures facing toward the LEDs or lamps • They have highest performance when used with collimated or narrow (up to 30 degrees) input beams,

such as an LED with TIR lens or parabolic reflector • The diffuser may be tilted relative to the input beam to fine tune the angle and light profile • Other angles and spreads are available on a custom basis • Bright View applications engineers can assist with product choices and help your design achieve peak

Bright View patent-pending BrightWing™ diffusers provide an efficient “batwing” distribution to help luminaires achieve a flat-field beam profile, uniformly illuminating a floor or work surface without a central hot-spot. They work equally well with LED and fluorescent sources. Patent application(s) pending. Luminaires with flat-field distributions can usually provide highly-uniform illumination at a greater ceiling spacing than their lambertian counterparts. Light distributions are determined by the light source, cavity geometry, and choice of diffuser. For this reason, Bright View offers several options in the B-series as well as application engineering to help optimize light designs. Request the Batwing Applications Notes for more detailed information.
