Angle Bending Diffusers

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.

Description Bend Angle1 Additional Diffusion Efficiency in typical LED luminaire2
A-AB20 Strong Angle Bend with limited backscatter 21° 5° (cross-wall and toward-wall diffusion) 90 - 94 %
A-AB08 Slight bend with strong cross‑wall diffusion 60° (cross-wall diffusion)
20° (toward-wall diffusion)
90 - 94%

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 performance
