Coelux

Coelux S.r.l. presents a compelling investment case in the architectural lighting and deep-tech sectors, having been established in 2009 as a spin-off from the University of Insubria. The company was founded by Professor Paolo Di Trapani, whose extensive research in physics at the university directly led to the development of the core technology. His academic background and decade-long dedication to simulating natural light indoors provide a strong foundation for the company's scientific credibility.

The firm's business revolves around a high-tech window system that artificially reproduces the appearance and optical effects of natural sunlight and a blue sky. This is achieved through a sophisticated interplay of three core components: a custom LED projector mimicking the sun's light spectrum, an advanced optical system that creates the illusion of a distant sun, and a proprietary nanomaterial-coated panel that replicates the Rayleigh scattering effect, the same phenomenon that makes the Earth's sky appear blue. The result is a hyper-realistic skylight that can be installed in any indoor environment, fundamentally changing the perception of enclosed spaces.

Coelux operates on a B2B business model, selling its lighting systems directly and through distributors for integration into architectural projects. The primary revenue stream is the sale of these high-value lighting units. Target markets are diverse and include corporate offices, where the system aims to improve employee well-being and productivity; the healthcare sector, for enhancing patient recovery environments in hospitals and clinics; and high-end residential properties, offering a distinct feature for luxury homes. The company also targets the hospitality, retail, and transportation sectors, such as in underground train stations, demonstrating the technology's versatility in transforming windowless environments.

The product portfolio includes various systems like the CoeLux 45 HC, which offers a 45-degree sunbeam, and the CoeLux LS (Long Sky), which creates the illusion of an endless sky. These systems are not merely lighting fixtures but experiential products that address the human need for natural light, a condition known as biophilia. By bringing the physiological and psychological benefits of sunlight indoors, Coelux has created a new category of architectural solutions with significant market potential across numerous industries worldwide.
