In another horticultural example of how LEDs can be finely tuned to suit different crops, Signify said that two French cucumber farms have installed greenhouse solid-state lighting (SSL) systems that optimise year-round growth of the popular salad vegetable.
Jardins Réunis and Cheminant, both close to the city of Nantes near the northwest coast, have deployed Signify’s Philips GreenPower LEDs set with a recipe that delivers brightness and frequency levels believed to be ideal for cucumbers. The passively cooled SSL also steers heat away from the crop, which likes temperatures from around 75° to 80°F.
Nanoco (LON: NANO) harnesses the power of nano-materials. .Nano-materials are materials with dimensions typically in the range 1 – 100 nm. Nano-materials have a range of useful properties, including optical and electronic. Quantum dots are a subclass of nano-material that have size-dependent optical and electronic properties. The Group produces quantum dots. Within the sphere of quantum dots, the Group exploits different characteristics of the quantum dots to target different performance criteria that are attractive to specific markets or end-user applications such as the Display and Electronics markets.
