LEDs as a light source have delivered on the promise of energy efficiency and long life. Cooledge develops technologies that enable the next step in the evolution of lighting to fully integrated, digitally controlled surfaces that are part of architecture, not added to it.
Immersive illumination is a subjective feeling of being surrounded by light in a way that feels comfortable and natural, like being outside. Immersive illumination is surprising: it delivers high levels of illumination but “feels like less” because we are used to experiencing localized higher levels of illumination created by traditional points and lines of light as inherently bright and in many cases somewhat uncomfortable.
Much as a diffuse sky delivers high levels of light by virtue of scale, the immersive illumination that is experienced under a luminous ceiling similarly does not require a large number of lumens per area, unlike troffers and linear pendants that supply much of the general illumination in public spaces today.

Continuous luminous ceilings deliver substantial levels of illumination without the highly localized concentration of lumens found in traditional luminaires.
Download DetailsCreating luminous surfaces for illumination requires a unique understanding of the interaction between light and architectural materials.
Cooledge uses its knowledge and expertise in photometric analysis to integrate and optimize SURFACES that deliver digitally controlled immersive illumination for creating more open tailored environments.
Cooledge FABRICated Luminaires and Specialty Illumination Solutions can replace acoustic clouds AND provide illumination in a single product.
The Noise Reduction Coefficient is a value used to characterize the ability of a material or object to absorb sound. FABRICated Luminaires provide better acoustic performance than many typical building materials. For open concept spaces, Suspended models may be ordered with an NRC value (0.75) that delivers similar performance to acoustic ceiling materials.
As a company with extensive experience and expertise in lighting, Cooledge has put together this brief guide to acoustic fundamentals and how they can be combined with lighting products to deliver an exceptional experience for your eyes… and ears.

Many products offer tunable white capability. Some offer dimming and some offer constant lumens. Cooledge delivers both.
Some products simply add the light output from a warm and a cool LED together resulting in more light output at CCTs in between the two endpoints
Some products are able to provide constant light output at all CCTs in their tunable range but at the cost of being able to dim.
A key aspect in the understanding of the interaction between light and human physiology is the effect of flicker generated by electric sources of light. In the past, before the adoption of high frequency ballasts, you may have heard people complain about fluorescent lights, however, it is with the widespread adoption of LED sources that flicker has become an important design consideration.
Cooledge‘s constant voltage electrical architecture is designed for enabling large luminous surfaces of variable sizes, shapes, and site conditions using simple, standard products.
The Cooledge approach ensures that illumination is always uniform and consistent, independent of the size of the electrical load connected to the LED driver or the field modifications required to adapt to site conditions.
Constant current approaches are optimized for points and lines of light such as downlights, linear pendants, and troffers where the amount of light – and hence electrical load – is constant and the size and shape of the luminaire never changes.
When used for large luminous surfaces, constant current systems cannot match the uniformity of constant voltage designs and present significant challenges when required to adapt to site conditions.
Constant current systems are optimized for efficiency where flexibility and scale are not a requirement.
Cooledge TILE products provide uniform light no matter the scale and where obstacles or angles require modification
When constant current is used for large surfaces visible differences in intensity may result - especially where obstacles or angles require field modification.
