Controlling the output distribution of light depends on several components,
which aid in the selection of the appropriate optical film for your application
A
Type of light source
B
Distance between LEDs / bulbs
C
The angular output of the light source
D
The distance between the light source
and the optical film
E
The diffusion angle of the film
Calculating the final light output of the film Non-collimated light
The transmitted light output of the film has a lambertian angular output that is approximately equal to:
