B-Series Linear Batwing Diffusers

BrightView's patent-pending BrightWing™ diffusers provide an efficient “batwing” distribution to help luminaires achieve a flatfield 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, BrightView offers several options in the B-series as well as application engineering to help optimize light designs.

Usage Notes

  • B-Lxxx have two different sides. Light should enter the more specularly reflective (glossy) side – please see the BrightView Application Note on Batwing Diffusers for details.
  • BrightView B-series diffusers help sculpt light into an efficient linear “batwing” distribution.
  • Light distributions are determined by the light source, cavity geometry, and choice of diffuser, and may vary significantly depending on the specific luminaire design.
  • BrightView applications engineers can help optimize designs to achieve desired performance.
  • Other angles and degrees of nadir suppression are available on a custom basis.
  • BrightView applications engineers can assist with product choices and help your design achieve peak performance.

1Angles data are typical; they vary greatly depending on luminaire design.
