Deep red, far red and new purple CoB LEDs target horticulture
The Luxeon SunPlus Series of LEDs are tested and binned by photosynthetic photon flux (PPF). The portfolio of colors enables wavelength tuning for maximum crop yield in both greenhouse and vertical farming applications. The addition to the Luxeon SunPlus 35 Line of Far Red and Deep Red will enable designers of vertical farm and interweaving fixtures to tune the spectrum specifically for the crop being grown. The Deep Red (650-670 nm) and Far Red (720-740 nm) wavelengths join the existing Royal Blue (445-455nm), Lime (broad spectrum) and three shades of Purple with varying contributions of blue (2.5%, 12.5% and 25%) in a 3.5×3.5mm format.
In contrast to vertical farming where lighting is positioned a short distance from plants, greenhouse lighting requires deep penetration into the plant canopy, which is achieved with a directional CoB such as the Luxeon SunPlus CoB Purple (12.5% blue). The CoB form factor also means that standard optics, holders and drivers are available to help manufacturers accelerate time to market of their fixtures. The Luxeon SunPlus CoB Purple is available with 15, 19 and 32mm light emitting surfaces.
