GrowRay Technologies, a cultivator-owned cannabis technology company, invented the Triangular Extrusion Shade Reduction Bar for cannabis cultivators. It was developed to be used in tandem with GrowRay's full-spectrum LED lights and light sensing adaptive controller in greenhouses and all other growth applications.
When paired together, the system reduces energy consumption by optimizing efficient light across the plant canopy.
This week, GrowRay received a patent for its efforts. The U.S. Patent and Trademark Office issued U.S. Patent No. US 10900638 B2, Shade and Shadow Minimizing Luminaire.
The Triangular Shade Reduction Bar has a unique geometry that reduces the cost of supplemental greenhouse lighting by reflecting available sunlight into the plant canopy below.
The light bars are made of highly reflective aluminum to provide uniform, homogeneous PPFD (photosynthetic photon flux density) without additional shading.
The fixtures were recently selected by Lansing, Michigan-based New Genetics for its 15,000 sq. ft. grow.
According to the company, the Triangular Extrusion Shade Reduction Bar can also reduce the absorbed heat from the sun, which significantly lengthens LED lifetime.
