Artemy is a fully-automated tomato harvesting robot, according to its maker Certhon Build. “It uses AI to determine the ripeness of cherry truss tomatoes,” said the company. “Only ripe tomatoes are selected, and cherry truss tomato peduncles are cut using scissors attached to the top of the harvesting robot arm and stored in the loaded crates.” Harvesting continues under direct ...
Osram has introduced horticultural lighting leds with a ‘batwing’ output distribution. Implemented in Oslon Square Batwing, the distribution comes purely from a primary lens built into the pacakge. “Current LED fixtures often have a lambertian primary lens and no secondary optic, or a simple glass cover, which lead to hotspots with high concentration of light directly under the luminaire,” according ...
Osram has created a ‘white’ led specifically to work alongside native red emitting leds for horticultural growth illumination. In horticultural lighting, the name of the game is to direct most of the electrical input power into the red and blue parts of the spectrum needed for plants to grow. On top of this are requirements for people to be able ...
Osram is claiming “the most efficient LED for horticulture” following the release of its Oslon Square Hyper Red. The figures are: radiant flux of 1.030mW at 73% wall-plug efficiency photon flux of 5.7μmol/s at an efficacy of 4.0μmol/J at 700mA life of over 100,000 hours “even at high temperatures” Then “for applications with higher efficacy requirements”: 78% driven at 350mA 80% ...
RS Components is stocking SunPlus 2835 horticultural leds form Lumileds – devices whose output spectra are optimised for different plant growth applications – particularly to improve crop yield, either by complementing or replacing natural sunlight. The devices are binned and tested for photosynthetic photon flux (PPF), which determines the amount of photosynthetically active radiation (PAR) provided by a light source ...
Devon-based Plessey has launched another Hyperion-branded horticultural product line – this time a luminaire to spread light at leaf level – to complement its horticultural down-lighter. “Placing lighting within the canopy of high wire plants is an energy efficient way to increase light levels and yields in greenhouses that already have supplementary top lighting,” said the firm’s director of grow ...
Osram is aiming at farmers, horticulturists and viticulturists with a broad-band near-infra-red LED for in-field reflection spectroscopy. “One of the most important decisions that farmers and vineyard owners have to make involves getting the timing right for the harvest,” it said. “Simply scanning fruit or cereal crops with the near-infra-red LED installed in a smartphone or tablet produces reliable information ...
Lumileds has introduced a line of leds for plant growth rate and crop yield for plants and vegetable. Called Luxeon SunPlus 2835, “growers can choose a specific colour point using Purple or Horticulture White leds, or design a spectrum using the Deep Red, Far Red, Lime and Royal Blue emitters”, according to the firm, which claims: Horticulture White provides a ...
Sterling Suffolk will install Plessey LED grow lights in its 54,400m² greenhouse. The model is the Hyperion 1750, Plessey’s latest, and has a maximum light output of 1,750 micromole/s (equivalent to a 1kW SON-T, the incumbent discharge lamp technology – Plessey introduced the 1000 micromole/s Hyperion 1000 in 2017, equivalent to a 600W SON-T. All Hyperion grow lights come in ...
Lumileds has been growing red lettuce, and worked out that lime, green and purple coloured leds LEDs grow more of them, with increased beneficial nutrients. Slightly abbreviated, the conclusion of the company’s paper (‘Luxeon SunPlus series Lime leds produce high yield and nutrition in leafy greens‘) reads: This study showed that red lettuce Rouxai grown under specific LED spectra can ...
