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.

Angle Bending Diffusers

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
