Transparent Material Considerations for UV Optics in Horticultural Lighting Applications

Transparent Material Considerations for UV Optics in Horticultural Lighting Applications Advancements in UV LED technology have begun changing the horticultural lighting landscape. Research is still ongoing to discover the extent of benefits and best practices of using UV light in horticulture. Using optics in tandem with UV LED light systems can help reach performance goals and optimize growing. Although there are several UV- transmitting materials available, not all are equivalent or able to meet the requirements for UV applications. Justine Galbraith, glass engineer, and Sharayah Follett, market development manager at Kopp Glass, Inc. discuss the performance considerations of various UV-transmitting materials and how application challenges are addressed by integrating optical elements.

Enriching Horticultural Lighting for Faster Growth and Better Crops

Enriching Horticultural Lighting for Faster Growth and Better Crops Horticulture lighting is no new lighting application, but it gained momentum with the introduction and evolution of LED lighting, and it is meanwhile one of the fastest growing markets in lighting. Dr. Richard Blakey, Application Engineer at Würth Elektronik eiSos, explains how LED-based horticultural lighting can deliver even bigger advantages for commercial growers by introducing additional wavelengths that increase photosynthetic response - like Würth Elektronik's new members of the WL-SMDC SMD Mono-Color Ceramic LED Waterclear family that is used as a reference in the article.

UV LED Technology for Emerging Applications in Agriculture

UV LED Technology for Emerging Applications in Agriculture The Ultraviolet (UV) LED market has expanded five-fold in the past decade and is projected to grow to over $1 billion by 2025. A key trend expected to influence the market is the ability to expand into new applications, including agriculture. UV light, at proper frequency and dose, can increase the production of active substances in medicinal and traditional plants and it can also help maintain a healthy growing environment. But to fully take advantage of UV LEDs, some major re-design considerations are required. Terrance Berland, CEO of the Violet Defense Group, the parent company of Violet Gro, will explain which considerations these are; for instance, why it is crucial to incorporate the appropriate lens material.

Trends in Horticulture Lighting

Trends in Horticulture Lighting Cree has been a leader in general lighting applications for over 20 years and has customers ranging from restaurant chains to global government agencies. Paul Scheidt began his career in Cree in 2005, working on the development of their lighting applications. During this time, he has seen an increase in the horticulture lighting application. LED professional spoke to Paul Scheidt about horticulture lighting and what he thinks is behind this recent trend. He also shares his views of what he thinks the future holds for both Cree and horticulture lighting applications. Read more »

Paul Scheidt, Cree - Horticulture Lighting

Paul Scheidt, Cree - Horticulture Lighting "When you go into horticulture application the light output level directly correlates to the yield that you see in the plants. There is no buffer, when lights dim, the yield goes down. If something degrades very quickly and is 100% for one growth cycle then goes down to 90% for the second growth cycle, you will see a reduced yield. There is no room for adjustments."

SSL Growth Strategies and USDA Corn Breeding Objectives

SSL Growth Strategies and USDA Corn Breeding Objectives The SSL horticulture lighting industry has become one of the fastest growing branches of lighting worldwide. Much research has already been done in regards to horticultural SSL technology and continues to be rigorously explored. While most other inputs for plant growth are monitored and controlled based on plant needs, it is still common practice for light control to be rudimentary (on/off). Brandon Newkirk, Marketing Communications Manager at LumiGrow Inc., gives a short overview on the current state of dynamic LED lighting with a focus on USDA corn breeding trials and objectives.

Bio-Effective Lighting for Humans, Livestock and Plants

Bio-Effective Lighting for Humans, Livestock and Plants Mood lighting is often misleadingly interpreted as HCL. But HCL is much more because it includes biologically effective light that is beneficial or dangerous, depending on the correct application. While the relevant parts of the radiation spectrum may differ, light is also biologically effective for plants and animals and it is used to achieve well-defined effects. Volker Neu, General Manager LED at Vossloh-Schwabe Lighting Solutions, presents examples, discusses similarities and differences between humans, animals and plants in respect to the relevant spectra, and scrutinizes possible consequences.
