In optics, a prism is defined as a transparent solid body that has three rectangular lateral surfaces and two triangular faces that are inclined at an angle. The angle at which the surfaces are inclined is known as the angle of the prism. It is also known as refracting angle. The other important term in the prism is the angle of deviation of a prism. It is defined as the angle between the incident ray and the emergent ray. Following is the formula used for calculating the angle of deviation:

Large setbacks require more visible luminaires, while shorter setbacks let designers hide their luminaires more effectively—but they require specialized optics.

Color Kinetics takes a flexible, application-first approach to optics. We examine the real-world requirements of the specific application, then develop the right optics. It’s a very different approach than simply choosing the easiest or least expensive option available.

You can't anticipate every facet of a lighting installation. Between design and implementation, a lot can change. Inflexible optics don't allow for these changes. But flexibility in the optical design, as well as in the field installation, enables designers to make adjustments without having to start over, add luminaires, or incur other expenses.

PureStyle’s optical system enables extremely short mixing distances, so it excels in cove lighting applications where traditional linear luminaires can’t compete.

Aiming and adjusting are simple to complete in the field, without requiring accessories. Luminaire rotation and other features give you the flexibility you need.

The extensive breadth and depth of our offerings includes luminaires that have integrated optics that require no adjustment, as well as ones with field-changeable lenses. These options ensure that you get the luminaire—and beam spread—that you need to achieve your vision.

At their core, optical systems are about controlling and transmitting a beam of light. While that goal may sound simple, optics require careful research and design to ensure that they meet the needs of the marketplace. Along with the LED selected for use within a luminaire, optics are a critical element that help determine the final quality of white or color light created by the luminaire.

Our dedicated team of optics designers have the skills and experience necessary to envision the best possible optical system for a specific need—then deliver it in an innovative, fully integrated luminaire.

For decades, Color Kinetics has made a significant commitment to investment in research and development, staffing our labs with expert optical engineers and equipment. This dedication to innovation enables us to design and manufacture industry-leading optical systems. Here are some of the reasons why our approach to optics is different—and better able to meet your needs.

Intelligent, customized optics require fewer optical losses, delivering maximum illuminance, color uniformity, and more punch.

When white light is made to pass through a prism, a spectrum of seven colours is formed which shows that white light is a mixture of seven different colours. Prism only acts as a medium for the separation of the seven colours. When light falls on the glass prism, refraction takes place. Since the wavelength of different components of light is different and the frequency is constant, each component gets deviated by a different angle due to the difference in velocity in the glass medium. The red colour having the maximum wavelength deviates the least and forms the upper part of the spectrum whereas violet having the least wavelength deviates the most.

Building owners and other clients want to lower their energy use wherever possible—not just for cost reasons, but to achieve sustainability and reduce environmental impact. Advanced optics use LED light more efficiently, reducing spill light and other energy-sapping issues—and getting the most out of every lumen.

We focus on the applications and light effects our customers are trying to achieve—then work to create an optical system that meets the requirements of even the most challenging design vision.

interior or exterior. Here we take a look at how the optics inside a luminaire help meet the specific challenges faced by today’s lighting professionals.

Dispersion is defined as the separation of white light into different colours when the light is passed through the prism. The scattering of light depends on the wavelength of the light. Therefore, it can be said that the degrees of deviation is dependent on the wavelengths. The deviation in the path of the light is inversely proportional to the wavelength.

Few lighting professionals have ever seen the optical system housed inside an LED luminaire. But the optical system, or optics, make a big difference for interior and exterior applications. Innovative optics help meet the needs of today’s challenging applications—from more flexible cove lighting to brighter, more consistent illumination of tall buildings and iconic landmarks.

No one wants complicated installations. Advanced optics can let you achieve more—more performance and illuminance—with fewer luminaires. And in the long run, fewer luminaires reduce maintenance, as well as costs.

We’re flexible, designing optics to meet the specific needs of our customers’ key lighting applications. Narrow beams of extremely bright light with remarkable punch? Even light that can be used with very short setbacks? With our optical expertise, we can deliver it all.

ReachElite and other exterior luminaires bring impressive dynamic color lighting to façades, landscape features, and other exterior details, creating a unique look and impressing guests. Beyond beauty, LED lighting from Color Kinetics also delivers new efficiency and energy savings, while reducing maintenance.

Our optics deliver light where you need it, with less waste. Efficiency reduces total costs and the amount of power required.

Consistency is one of the most important criteria for judging LED light quality. Lighting professionals want consistent light, without banding, fading, or other issues. Optics play a key role in consistency by ensuring steady, uniform performance over time, without opacity or other issues. Related technologies also need to work in tandem with the optical system to help ensure consistency.

Red light suffers the least amount of deviation and violet the most. Since all the wavelengths suffer different angles of deviation, when white light passes from one optical medium to another, different colours of the light split, and this phenomenon of splitting of light into its components as result refraction is called dispersion.

If you want to illuminate a large façade, you need to know that your luminaire can reach the highest point of the building with the same illuminance, without hot spots or fading. Optics can make that happen by delivering maximum punch/throw and uniform light across an entire surface, with extremely low variation in white or color light.

Our OptiBin technology begins the color consistency process by grouping (or binning) LEDs by flux as well as center wavelength. This proprietary binning optimization process ensures the uniformity and consistency of hue and color temperature for our luminaires. Our Chromasync advanced color consistency technology improves consistency from luminaire to luminaire. Colors are more consistent, regardless of the specific LEDs used, date of manufacture, and other variables. The result? High color precision.

Center beam candle power (CBCP) is a measurement of luminous intensity expressed in candelas. It represents the intensity of a beam of light in the brightest part of that beam, the center. CBCP is measured in footcandles, which is a more accurate measurement of delivered light than lumens.

At Color Kinetics, we’ve made a significant commitment to optimized optical systems and innovative optical design. Why? Because we know that optics matter, delivering major benefits, along with great light.

Flexibility is the hallmark of advanced LED lighting solutions, which can change from beautiful white light to dynamic color-changing light effects with the touch of a button. Lighting from existing ledges can highlight the upper reaches of an interior space, drawing attention to details that might have gone unnoticed.

One of the promises of LED lighting is that it lowers maintenance because of the inherently long lifespan of the LEDs. Optics can yellow and become opaque over time, reducing performance. But an advanced optical system doesn’t change over years of use. This is particularly important for high-visibility, long-term installations, such as bridges, where accessing luminaires can be challenging.

White light is primarily composed of light of different wavelengths (colours) viz. violet, indigo, blue, green, yellow, and red with red having the highest wavelength while violet having the lowest wavelength.

Bright, consistent white light from the Graze family of LED luminaires highlights façades, architectural details, and other elements of historic buildings, as well as new construction. Advanced optics enable the luminaires to stay concealed, keeping the focus on the light, not the luminaire.
