Extending the growing day all year round

Modular lighting with intelligence built in

We wanted to build a solution that would make supplementary lighting more effective and less expensive so that indoor farmers could focus on growing healthy crops economically. Based on a rigid 3-tier grid of aluminium busbars (tubes), the system can support LED lights, cameras and sensors to monitor crop development as well as lighting the crops.

It can be remotely controlled or set to switch on when natural sunlight fails or fades and timed to deliver light for a maximum number of hours per day. It can also be set to deliver a particular quality of light, mimicking Mediterranean, savannah, tropical, temperate and other growth climates.

Supplementary Lighting 3

To solve the problems of appropriate light intensity and light pulse width modulation (PWM), IGS has developed a patented 3 phase technology for LED lights that varies intensity and PWM infinitely in .01% increments over all wavelengths simultaneously. Our platform achieves this while maintaining a 90%+ electrical efficiency from grid to LEDs.

As we have worked to develop our technology, LEDs have become increasingly cheaper and more efficient, helping to reduce overall capital costs.

We’ve recently filed two patents to support our supplementary lighting system, and have shown an increase in LED efficiency by up to 50%.

Looking beyond lights

Increasing the efficiency of the lights was step one. Ultimately, we wanted to conceive an ecosystem that supported smart energy use.

We’ve developed a blend of machine learning (ML) and artificial intelligence (AI) to smartly control light and minimise energy consumption. The system provides multi-modal control of lighting including spectrum (via pulse & dim) delivers the light plants need to grow with optimised efficiency, helping vertical farmers to achieve maximum yield. Our patented technology features zero flicker, further optimising growing conditions for an indoor environment.

IGS’s supplementary lighting system can work alongside our broader vertical farming technology platform to provide indoor farmers with scale, efficiency and reliability.
