A range of colour and white LED emitters for horticultural lighting have been announced by LED Engin.
Alongside the typical colours used in horticultural applications (Blue 450nm, Deep Red 660nm and Far Red 740nm), the company is adding custom solutions that include 3 new direct colours (Violet 415nm, Royal Blue 436nm and Cyan 500nm), a phosphor-converted green and full white CCT options (2200K-6500K).
Together with the standard LED emitters spanning from UV 365nm to Infrared 940nm, this means that a variety of purpose-built lighting solutions can be created to deliver optimised spectra for improved crop productivity.
LED Engin’s emitters are available in single-die packages, as well as multi-die, multi-channel, high-power density ceramic packages of up to 25 die in a single emitter, rated for 3-80W maximum power dissipation. The emitters feature the industry’s lowest thermal resistance of 0.5–6.0°C/W, which ensures efficient heat dissipation resulting in excellent flux output and flux maintenance over time. The packages are designed with a glass primary lens to deliver exceptional robustness in challenging growing environments with high ambient temperature and humidity. All these features, combined with highly efficient LED die in all colours, deliver enhanced spectra with high Photosynthetic Photon Flux (PPF) promoting plant growth and making year-round cultivation possible.
David Tahmassebi, President and CEO of LED Engin, comments: “Plants respond to varying colours and intensity, and LED Engin provides a complete solution. In addition to the conventional colours used in horticultural illumination, we offer complementary colours to enable fixture manufacturers to either create a full spectrum that mimics the sun or a proprietary spectrum to suit specific needs, allowing them to differentiate their products from typical horticultural fixtures.”
Unique and proprietary bespoke designs can be tailored to specific needs and applications. LED Engin supports emitters with customised die configuration, collections of single-colour emitters shipped in pre-defined ratios, plus complete integrated system modules for easier assembly. More info can be obtained from LED Engin’s sales team as well as its distributors.
