Для организации светодиодного освещения растений Samsung выпускает унифицированные модули. В официальном пресс-релизе корпорация сообщает, что разработала новые решения с повышенной эффективностью образования фотонов. Модули LM301H с длиной волны 5000K (белое свечение) потребляют 65 мА и относятся к решениям с потреблением средней мощности. Новые светодиоды в составе модулей генерируют излучение с эффективностью 3,1 микромоля на джоуль. Это самые эффективные светодиоды в указанном классе.
Благодаря повышению плотности излучаемых светодиодами фотонов, каждый светильник может использовать на 30% меньше светодиодов, что сэкономит средства на осветительное оборудование без ухудшения его характеристик, если сравнивать с модулями предыдущего поколения. Если использовать то же число светодиодов, то эффективность освещённости светильников можно увеличить как минимум на 4%, что позволит улучшить интенсивность роста.
Каждый светодиод имеет размеры 3×3 мм. Эффективность излучения повышена благодаря новому составу слоя, преобразующего электричество в фотоны. Кроме того, усовершенствованная конструкция светодиодов позволяет снизить потери фотонов при их прохождении внутри светодиода.
Белые пакеты LM301H охватывают более широкий спектр света - от синего и зелёного до красного, повышая иммунитет растений к болезням и обеспечивая большую питательную ценность.
Новые LED-продукты 2019 года южнокорейский техногигант представит на ежегодной выставке LIGHTFAIR International, которая пройдёт с 21 по 23 мая в Филадельфии (штат Пенсильвания, США).
Чуть ранее, в ходе февральской выставки кухонной техники KBIS в Лас-Вегасе (штат Невада, США), Samsung представил новейшую систему Chef Garden для выращивания свежей зелени в домашних условиях, где также применена революционная LED-технология. Chef Garden полностью интегрируется со смарт-холодильником Family Hub следующего поколения и предлагает простой, экологически чистый способ выращивания растительных продуктов. Система Chef Garden автоматически регулирует длину световых волн, что позволит выращивать или дольше сохранять в свежем виде различные продукты. Таким образом, владельцы Chef Garden смогут наслаждаться свежими фруктами и овощами круглый год, причём без применения пестицидов. Последний пункт для многих людей особенно актуален, поскольку в мире ширится спрос на экологически чистые продукты.
Samsung Sets New Photon Efficacy Level in White LED Packages for Indoor Farms
High photon efficacy allows more light to reach plants for healthier growth
and enables indoor farms to save on energy costs
Samsung Electronics, a world leader in advanced digital component solutions, today announced an industry-leading enhancement to its mid-power LED package – the LM301H – for horticulture applications, such as greenhouse and vertical farming*. At 3.10 micromoles per joule (μmol/J), the newly introduced LM301H now features the highest photon efficacy** among today’s mid-power white LED packages.
“This breakthrough in photon efficacy will go a long way in helping indoor farm owners to maximize plant growth and quality, as well as their profits,” said Un Soo Kim, senior vice president of LED Business Team at Samsung Electronics. “We are committed to continue innovating white LED solutions optimized for healthier plant production as we solidify our leadership in the horticulture lighting industry.”
As a result of this industry-leading photon efficacy, lighting manufacturers can use 30 percent fewer packages in each luminaire to achieve the same efficacy level as the previous version of the LM301H, allowing for smaller and lighter lamp designs as well as lowered manufacturing costs. In addition, by using the same number of packages, the light efficiency of a luminaire can be improved by at least four percent, enabling indoor farms to reduce their energy use.
Samsung is able to achieve this advancement in photon efficacy by optimizing the chip’s light-emitting layer to convert electrical energy into photons with greater efficiency, while an improvement in chip structure minimizes light loss, delivering more light to plants.
Furthermore, thanks to Samsung’s advanced flip-chip design, the LM301H requires no wire bonding, which helps extend the packages’ performance and reliability. Titanium dioxide around the chip also ensures higher durability when exposed to agricultural chemicals.
To promote even more balanced plant growth, the white LM301H packages encompass a broader spectrum of light from blue and green to red, enhancing immunity from plant disease and providing greater nutritional value.
Samsung expects to begin mass producing the new LM301H packages at the end of this month and will be showcasing them at LIGHTFAIR International 2019 in Philadelphia, Pennsylvania, from May 21 to 23.
* Vertical farming is the practice of growing crops in stacked layers to optimize the use of space. It typically takes place in controlled indoor environments.
** Photon efficacy (PE) indicates the light efficacy level for photosynthesis in plants and is measured in micromoles per joule (μmol/J). Efficacy is the measure of how well a light source produces visible light.
*** Photosynthetic photon flux (PPF) indicates the total amount of photons in the photosynthetically active radiation (PAR) range – a spectral range between 400 and 700nm – that can enhance plant photosynthesis and is measured in micromoles per second (μmol/s).
Introducing Healthy Vertical Farming
Agricultural innovations are essential for feeding our ever-growing global population. Especially these days, as industrialization and global warming continue to negatively affect soil fertility and reduce the amount of arable land.
According to the United Nations, the world’s population is set to reach 9.8 billion by 2050. Such a large population would require approximately 1.7 times more food than is available now.
One potential solution for addressing the world’s need for more healthy and abundant food production is vertical farming – a process that’s growing increasingly popular in places like Europe, the U.S. and Japan, and involves food being grown indoors in vertically stacked layers.
Stable Food Production
What makes vertical farming such an efficient and viable means to produce food are the facts that it (1) saves space, and (2) allows farmers to grow crops all year round, regardless of climate or season.
Interest in vertical farming has been rapidly growing in recent years. Market research firm MarketsandMarkets predicts that the global market for vertical farming will be worth $18.4 billion by 2022, which is twice as much as the market was valued in 2016 ($9 billion).
Innovating for a Greener Future
The movement for healthy, sustainable food production is spreading across the world, and Samsung is committed to driving innovation in this area.
Last spring, Samsung announced the launch of a wide range of horticulture LED offerings that produce a broad spectrum of light to support healthy plant growth. On April 23, Samsung introduced an update to the LM301H, which features the highest photon efficacy among today’s mid-power white LED packages. The company has also revealed a number of exciting innovations designed to make it easy for consumers to grow and enjoy fresh, healthy vegetables from the comfort of their home.
Samsung also made waves at this year’s Kitchen & Bath Industry Show (KBIS) in Las Vegas with its all-new Chef Garden technology, which offers a simple, environmentally friendly way to grow food at home. Chef Garden integrates seamlessly with Samsung’s next-generation Family Hub refrigerator, and automatically regulates light wavelengths to enable users to grow and enjoy fresh, pesticide-free fruit and vegetables all year round.
“There is a growing interest in healthy food,” said Chohui Kim of Samsung Electronics’ LED Technology Center. “Horticulture LED is playing a key role in vertical farming and indoor crop cultivation, and we are looking to expand its applications in various fields.”
