The CineoColor™ Optimized Spectrum

Cineo difference graph


Regardless of the technology employed, lighting manufacturers have the opportunity to design the color spectrum of their light source. This consideration affects the color temperature of the device and the overall spectral characteristics at any given CCT. Most LED lighting manufacturers choose an “off the shelf” spectrum from LED devices designed for general lighting, as these are lowest cost, highest efficiency and most readily available. LEDs built for the general lighting market are designed to meet very different criteria than the critical lighting requirements for image capture, particularly in the lower wavelengths. Many different materials can be used to create a white light spectrum, and lower-cost materials are susceptible to instability of the spectrum over time, resulting in a noticeable green-shift. Additionally, these LEDs do not adequately render deep reds, leaving skin tone and saturated warm colors looking washed-out on camera.

Cineo has custom-designed the spectra of every fixture in our product line for both Remote Phosphor and Color-tuned technologies. Our phosphor chemistry, originally developed for our Remote Phosphor panels, shows negligible color shift after 100,000 hours of operation. Our CineoColor LEDs use the same stable materials as our phosphor panels, resulting in nearly identical spectral characteristics and color stability. Rare-earth materials used to generate the spectrum in all Cineo products extend the light gamut to the near-IR spectrum, resulting in healthy-looking skin tones and accurate rendering of saturated colors.

By designing proprietary recipes for all our lighting fixtures, we can guarantee accuracy, consistency and longevity of our entire product line.

Remote Phosphor

Since the introduction of digital lighting into film, television, and photography, color rendering has been an issue. The inherently discontinuous light spectra of traditional LED sources has made it difficult for a digital light to approach the color rendering quality of a black-body radiator like a tungsten filament.

Cineo’s remote phosphor series utilizes precision phosphor formulations deposited on interchangeable CTI specific panels, to eliminate those color-accuracy issues. Instead of relying on LEDs as a source of illumination, these fixtures rely on a separate phosphor substrate to emit high-quality predictable light when excited by high-frequency wavelengths emitted by our proprietary blue LEDs. The result is a continuous linear spectrum unlike any other digital light developed for image capture.

Think of a remote phosphor array as you would a CRT screen found in legacy television sets. RPT employs a transparent surface onto which a special phosphor coating is applied. These phosphors are excited at two precise wavelengths, in this case with LEDs completely separated from the phosphor substrate, resulting in very stable high-CRI white light.

Color temperature remains consistent throughout the lifetime of the fixture, because the phosphors are not subject to heat degradation, unlike typical white LEDs. Color consistency fixture to fixture is also guaranteed, because it’s easier to accurately coat the phosphor “recipe” onto a substrate instead of directly onto a diode.

Like all Cineo products, our remote phosphor fixtures are focused on attaining the highest quality light and utmost power efficiency.
