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-AB08 | Slight bend with strong cross-wall diffusion | 8º | 60º (cross-wall diffusion) 20º (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
- 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.
