New Horticulture LEDs Improve Crop Yields


Lumileds unveiled new LEDs designed specifically for horticulture applications. The SunPlus 20 Line fulfills the needs of greenhouses farmers who want to enable 24 hour or year-round growth with added supplemental high bay lighting, the firm says.

Lumileds’ LUXEON SunPlus Series LEDs, available from Mouser Electronics, support indoor and greenhouse farming by delivering precise light wavelengths and optimized spectra that complement or replace natural sunlight for improved crop yields.

The LUXEON SunPlus 20 Line is comprised of 2.0 x 2.0 mm high power LEDs in Royal Blue (440-460 nm), Deep Red (655-675 nm), Far Red (720-750 nm), Lime (broad spectra) and Cool White.

Growers can develop single channel solutions using key wavelengths for photosynthesis, blue (420-480nm) and red (620-670nm). Alternatively, they can develop multi-channel solutions with select LEDs to optimize light output for different stages of the plant’s life cycle, such as seedlings, germination, vegetative growth, flowering, etc.


“Only Lumileds bins its horticultural LEDs by PPF [photosynthetic photon flux in µmol/s] and wavelength, so lighting designers know exactly what they are getting and can design their fixtures for optimal plant productivity,” said Luis Aceña, Lumileds Senior Manager of Business Development. “The SunPlus 20 Line features a high PPF per LED, which leads to more compact solutions. In addition, because all the LEDs have the same focal length, it is very effective,” he added.

The firm also offers the SunPlus 35 line, part of the Luxeon SunPlus Series, including LEDs for vertical farming with multiple stacks of growth trays. These LEDs offer bright lighting from short distances with high uniformity. The series includes Blue (440-460 nm), Lime, White and three shades of Purple mid power LEDs in a 3.5 x 3.5 mm format.

“Our Purple LED offerings are distinct in that they are long-lasting, high efficiency blue LEDs under red phosphor, offering the highest uniformity for consistent growth. Other companies are combining blue and red LEDs to get purple hues, but this is problematic because red LEDs age faster than blue ones, so the red / blue ratio keeps changing over time, obtaining unreliable growth results,” said Aceña.

The firm offers Purple LEDs with different blue PPF relative to PPF total across the photoactive region (400-700 nm). The Purple (2.5% Blue) LED encourages stem growth and flowering, the Purple (12.5% Blue) LED encourages general purpose growth, and the Purple (25% Blue) LED encourages vegetative growth for larger leaves.
