B-Series Linear & 2D Batwing Diffusers
BrightView's 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.
B-Series Linear Batwing Diffusers
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.
| Product | Typical Luminaire FWHM Angle1 | Degree of Nadir Suppression | LED Hiding Power | Efficiency in Typical LED luminaire1 |
| B-LM5E-XXXX-HE20 | 127º | Strong | Light | 92 - 96% |
| B-LM5E-XXXX-HE30 | 124º | Medium | Medium | 92 - 96% |
| B-LM5E-XXXX-HE40 | 120º | Light | Med-Strong | 91 - 95% |
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.
By making a special micro lens array on the surface of the film, these diffusers provide an efficient 2D Batwing distribution to help luminaires achieve a flat-field beam profile, uniformly illuminating a floor or work surface without a central hot spot.
Advantages
