Technology & Benefits

Why Does Reflectance Matter?

Every time a light ray is reflected, a portion of the light will be absorbed by the reflecting surface. Many current fixture designs involve multiple reflectors to achieve good aesthetics. A high performance reflector will minimize the absorbance from multiple bounces and maximize the usable exiting light.

Even a small difference in reflectance can make a big difference in lighting efficiency.

Why does high diffuse reflection matter?

High diffuse reflection helps provide the soft, uniform lighting experience most designers prefer for indoor lighting applications. It helps eliminate the glare and uneven “hot spots” or fluorescent lamp “stripes”. In LED light fixtures, diffuse reflection is critical in mixing color and hiding multiple lamp images.

Why does controlling light matter?

Light used to illuminate areas that do not need to be are just as wasted as if they had been absorbed. Designs that maximize effectiveness in controlling light directionality allow for smaller and more efficient fixtures, saving on up-front costs and energy savings.

Applications

WhiteOptics® Reflect, Diffuse, Control materials allow unique design approaches in all lighting applications.

Indirect


Reflect: LEDs can be aimed directly at the WhiteOptics® reflector surface and be completely diffused, without showing LED imaging or hot spots.

Diffuse: For indirect light designs using WhiteOptics® reflectors, diffusors or lenses are not typically needed due to the super diffuse reflection of the WhiteOptics® reflector surface.   This results in simplicity of design, reduced cost and an elegant aesthetic.

Edge-Lit


Reflect: Used in edge-lit designs, WhiteOptics® reflectors allow the highest light extraction efficiencies. WhiteOptics® unique, diffuse reflector surface mates perfectly with most light guide patterns to provide the most uniform extraction distribution and eliminates “mura” or wet-out non-uniformities from uneven surface coupling.

Diffuse: WhiteOptics® diffusors placed over light guides efficiently provide light uniformity and our micro-lens type structures can cost-effectively increase overall glare-reduction

Control: WhiteOptics® prismatic glare reduction structures work to dramatically reduce high angle glare from lambertian sources and can significantly lower UGR (Unified Glare Rating). WhiteOptics® control structures can also be used to create unique distributions not typically achievable with Light-guide panels; narrow beam, batwing and asymmetric distributions are possible in thin profile edge-lit formats opening new possibilities.

Back-lit


Reflect: WhiteOptics® reflectors efficiently recycle the light back-scattered off of the lens and cavity walls. WhiteOptics®’ highest diffuse surface helps to minimize hot spots and/or mix colors while maximizing optical efficiency.

Diffuse: WhiteOptics® micro-structured diffusors efficiently work to hide direct LED images, create uniformly lit surfaces, improve color mixing and/or provide unique diffused looks.

Control: Placed over a diffused or concentrated source, WhiteOptics® control structures can be used to reduce high angle glare, form defined beam angles, create batwing distributions or create unique symmetric or asymmetric distributions.

WhiteOptics® materials can be incorporated into energy efficient SSL luminaries to:

• Maximize light reflection, output and brightness.

• Use fewer LEDs and/or lower wattage LEDs, lowering overall system costs and extending luminaire lifetime by reducing system temperature.

• Improve uniformity of light distribution, eliminating “dots” and glare for better overall optical aesthetics.
