Samsung has added full-spectrum white LEDs to its horticultural-lighting-targeted portfolio along with new blue, red, and far-red LEDs, and announced horticultural modules, while Luminus Devices touts CMH replacement and Seoul Semiconductor wins award for SunLike.


Samsung Electronics has announced new LEDs for its horticultural lighting portfolio and new level 2 modules  earlier this year. Luminus Devices has announced its 4th generation (Gen 4) of chip-on-board (COB) LEDs with the new products enabling solid-state lighting (SSL) replacement of 70W ceramic metal halide (CMH) spotlights. Seoul Semiconductor and Lux have announced that the SunLike LED won a Lux Award for enabling technologies.

Horticultural LED lighting

牛彩网3d Samsung’s prior horticultural offering included a high-power red LED and some phosphor-converted white mid-power LEDs. The company has now added high-power white LEDs as well as the aforementioned  as we have covered in a feature article on the topic. The additions to the product line mean that Samsung can now support applications ranging from top lighting in greenhouses or indoor growing chambers to indoor vertical farms that house layers of plants with lighting very near the plant canopy.

Samsung’s latest packaged LED offerings power up horticultural SSL products with full-spectrum light.

牛彩网3d Samsung said in many applications, the full-spectrum white LEDs will enable lower-cost luminaire designs relative to an approach that uses more-expensive monochromatic LEDs. “Samsung’s full-spectrum-based horticulture LEDs present a new way of using LED lighting to improve plant cultivation at reduced system costs,” said Un Soo Kim, senior vice president of the LED Business Team at Samsung.

Plus, the white light is easier for humans to work under. Still, Samsung will also support luminaire designs that produce monochromatic red and blue for applications that benefit from those isolated bands.

Samsung further said it plans to bring its smart lighting technology to horticultural lighting. For more than two years, . “We plan to further expand our horticulture offerings by integrating the latest in smart LED lighting technology, including Samsung’s leading sensor and connectivity solutions,” said Kim.

The level 2 modules or light engines are yet another way that Samsung believes it can help its customers get to market faster in the horticultural sector. Indeed, the modules simplify the product design burden and come in form factors that match horticultural sector needs.

MH replacement

牛彩网3d Moving to the general lighting sector, there are some specific product niches where SSL has struggled to match the light quality of legacy source. One such niche is in the CMH spotlights that are used in demanding applications such as retail, where stores want merchandise colors to pop and grab the attention of shoppers. Such demanding applications are the specific target for Luminus’ new Gen 4 COBs.

“We’ve seen LED replacements for lower wattage CMH lamps, but we’re finally able to displace the 70W lamp, which has been the go-to choice of many retail lighting designers when they need a narrow beam spot to make the merchandise sparkle,” said Tom Jory, vice president of illumination at Luminus. “Only Luminus Gen 4 COBs enable small-form-factor fixtures with the punch of 70W CMH in combination with our unique spectral tuning technologies AccuWhite and Sensus.”

Luminus Devices says its new Gen 4 COB LEDs perform well under demanding conditions, maintaining color and luminous output while providing tunable color.

Luminus said the Gen 4 LEDs are unique in that they can reliably operate at a temperature of 120°C and when over-driven at three times the nominal current rating. The LEDs are said to maintain color and lumen maintenance over time even at such stressful operating levels.

SunLike award

Recent packaged LED news also came in the form of the Lux Award received by Seoul Semiconductor.  held in London and products across the SSL spectrum were recognized. The Enabling Technology of the Year Award was presented in association with LEDs Magazine to Seoul for the SunLike family. SunLike LEDs mimic the spectral power distribution of the sun across the visual range and offer potential benefits ranging from  to more .

And the , although the prevailing thoughts were that slow adoption has been mainly due to lack of available enabling components and that the mesh wireless scheme would soon become much more prominent.
