CLIENT

A Global Life Sciences innovator specializing in sustainable, bio-based protective compounds looking to leverage ancient evolutionary mechanisms of photosynthetic microorganisms.

02

BUSINESS NEEDS

The client aimed to scale from shallow, sunlight-dependent cultivation to high-density mass production within 5,000L photobioreactors by replacing inefficient external lighting with a specialized, industrial-scale internal solution powered by precise, high-intensity radiation.

03

CHALLENGE

To help our client achieve its goals, we overcome the following challenges:

  1. Environmental Resilience

    Environmental Resilience

    Engineering "water-sealed" modules capable of continuous operation while fully submerged in 5,000L bioactive environment.

  2. Spectral Precision

    Spectral Precision

    Delivering three distinct, mission-critical light ranges with laboratory-grade accuracy to trigger specific metabolic pathways.

  3. Thermal Management

    Thermal Management

    Dissipating heat generated by high-power LED arrays within a sealed PMMA enclosure to prevent culture overheating and LED degradation.

  4. UV Light Transmittance

    UV Light Transmittance

    Finding a way to ensure high light transparency at the UV edge without using traditional borosilicate glass.

04

SOLUTION

We engineered a modular, submersible lighting architecture featuring custom-designed three-wavelength light modules, optimized for deep-tank integration. The solution entailed:

  • Multi-Spectral Induction
  • Deployment of three specialized module types with wavelengths close to UV to allow granular control over biomass growth.
  • Advanced Encapsulation Technology
  • Design of custom-machined PMMA tubes with industrial-grade seals and 3D-printed structural components.
  • Active Internal Cooling
  • Integrated high-efficiency fan modules within the sealed tubes to manage thermal loads and ensure stable output.
  • High-Durability UV Optics
  • Utilizing specialized UV-transparent PMMA instead of fragile borosilicate glass to ensure maximum light transmission.

By moving the light source directly into the heart of the bioreactor, we've bypassed the physical limits of traditional cultivation. This system moves beyond simple illumination to provide precise control over evolution at scale.
