MF Series Micolens Film

Fusion Optix's new MF Series Microlens Film is here!  Direct your light where it needs to go!

In this reference design you can observe the difference in light output between left half of this 4' x 4" linear direct luminaire (with the MF Series Microlens Film affixed), and the right half (without any diffusion components). 

MF Series Microlens Film for LED Diffusion - Reduces Wasted Light Output at Wide Angles

As you can see, the right half of the guide has less beam control, emitting more light at wide angles, such as the 25° viewing angle of the above image.  On the other hand, the anti-glare MF Microlens Film on the left half reduces wide-angle light output, focusing the beam on its intended subject.  The MF Microlens Film also increases direct-view light output, as evidenced by this close-up image of the same luminare from immediately beneath it.

What are Light Guides


What Are Light Guides

Light Guides are a clever method of directing light in applications where direct light from the light source can not be used due to physical, economic, aesthetic or other restrictions.

Light guides (also called light pipes) are a major component in edge-lit LCD display back lights where there is a CCFL or LED light source at one or two opposite edges of a light guide, which extracts the light towards the viewer. This approach allows for the use of less powerful light sources while maintaining high screen uniformity and very thin display profiles.

With the growing popularity of Solid State Lighting (LEDs and OLEDs), light guides are becoming increasingly sought for the creation of ultra-thin sleek and stylish lighting and signage fixtures.

How Light Guides Work

Light guides rely on the combination of total internal reflection (TIR) and a light extraction method to create a flat thin evenly emitting surface. For TIR to occur light has to strike the inner surface of the guide at an angle smaller than a specific critical angle. All light rays that strike the surface at angles higher than the critical angle are transmitted. 

What sets apart light guides from mere plastic rectangles is that light guides greatly increase the chance of light being transmitted through the extraction sides. This can be achieved in two ways:

Critical Angle Transmission

In CAT numerous imperfections are introduced at the extraction surface that increase the chance of light reaching critical angle. Depending on the light source, light guide dimensions and other factors, special imperfection patterns and shapes are developed to ensure maximum light extraction.

Frustrated Internal Reflection

In FIR a scattering material is applied to the extraction surface. The scattering material has different optical density from both the light guide and air, which results in light being transmitted from the guide to the scattering material.

Designing Efficient Light Guides

There are several factors that influence light guide efficiency including mixing distance, edge coupling, light scattering and reflectance. You can read more about light guides and efficient light guide designs in our downloadable Light Control and Efficacy using Light Guides and Diffusers presentation at www.fusionoptix.com.

What is the difference between luminance vs. illuminance?

What is the difference between luminance vs. illuminance?

 When talking about light, one of the most confusing terms will be luminance and illuminance.  They are more or less used incorrectly by people, sometimes even by the people in the industry.


Luminance
Luminance is the density of luminous intensity in a given direction and falls within a given solid angle.
It is measured in cd/m2.
Luminance is often used to characterize the emission from a diffuse surface. It indicates how much luminous power will be perceived by eye when viewing the surface from a particular angle. Luminance remains the same regardless of the distance from the light source.

Luminance is the light that is coming out of a surface.

Illuminance
Illuminance is the density of photons which fall within a given surface area. It is measured in lux, or footcandle(fc).
Illuminance can be measured with a lux meter. For a given light source, the closer to a light source the illuminated area is, the higher the Illuminance value.

Illuminance is the light falling to a surface.

Illuminance is used in lighting applications to measure the amount of light reaching an object such as a wall. ...Read more
