EWLED technology overview
Lucciola’s EWLED technology replaces inefficient 2D geometries with a 3D light-distribution architecture, ensuring uniform photon exposure throughout the reactor, independent of its overall dimensions.
EWLED (Encapsulated Wireless LED) is a miniature cubic device that emits light uniformly in all directions from each face, maximizing photon utilization.
A multitude of EWLEDs is deployed in a packed-bed formation within the reactor vessel, wirelessly powered via induction, eliminating the need for direct wiring.
The reactor operates in plug flow reactor (PFR) mode, where reactants are pumped through a densely packed EWLED bed, ensuring consistent light exposure and optimized reaction kinetics.
Overcoming Key Industry Challenges of Photoreactors
Problem:
Photochemical reactions are severely impacted in media that absorb photons, leading to inefficiencies.
Solution:
In our EWLED reactor, the high LED surface area per unit volume allows photocatalysts to be directly coated onto the LEDs. This eliminates photon loss, enabling the use of less powerful LEDs while maintaining efficiency. Additionally, intermediates generated by the photocatalyst travel only a short distance before interacting with reactants, thanks to the closely packed EWLEDs, enhancing reaction kinetics.
Problem:
Scaling up microreactors while maintaining short photon travel distances—a key factor in reaction efficiency—is challenging. Traditional reactor designs struggle to achieve uniform photon distribution at scale.
Solution:
EWLED technology ensures a consistent photon path at any scale by maintaining a fixed distance between LEDs in a closely packed bed, regardless of reactor size. Due to the 3D geometry of EWLEDs, a significantly higher photon density per unit volume can be achieved, maximizing light utilization. Moreover, the uniformity of light density is maintained regardless of light intensity, ensuring consistent photochemical reaction performance across different operating conditions.
