Samsung Electronics Co., Ltd., 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).
