The client

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

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.

The challenge

  • 01

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

  • 02

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

  • 03

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

  • 04

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

Our solution

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

  1. Multi-Spectral Induction

    Deployment of three specialized module types with wavelengths close to UV to allow granular control over biomass growth.

  2. Advanced Encapsulation Technology

    Design of custom-machined PMMA tubes with industrial-grade seals and 3D-printed structural components.

  3. Active Internal Cooling

    Integrated high-efficiency fan modules within the sealed tubes to manage thermal loads and ensure stable output.

  4. High-Durability UV Optics

    Utilizing specialized UV-transparent PMMA instead of fragile borosilicate glass to ensure maximum light transmission.

Technology used

  • High-Power UV LEDs
  • PMMA UV-Transparent Tubes
  • 3D Printing
  • Custom Thermal Management

The outcome

The implementation enabled the client to transition from laboratory prototypes to a full-scale industrial production model. The custom internal lighting significantly increased the concentration of bioactive compounds by ensuring every liter of the 5,000L tank received the optimal spectral recipe.
