A-Series Asymmetric Direction Turning Diffusers

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.

Product Description Bend Angle1 Additional Diffusion Efficiency in Typical LED luminiare2
A-AB20 Strong angle Bend with limited backscatter 21º 5º (cross-wall and toward-wall diffusion) 90-94%
A-AB08Slight bend with strong cross-wall diffusion 60º (cross-wall diffusion)
20º (toward-wall Diffusion)

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
  • 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.
2Efficiencies are typical; they vary greatly depending on luminaire design. Bright View tests include: commercial 4-inch LED downlight module, linear LED fluorescent tube-replacement, 2'x2' LED troffer with clear acrylic cover.
