    Lumileds SunPlus LEDs Prove Effective in Horticultural Lighting Study on Lettuce by LESA

    Lumileds SunPlus LEDs LESA

    Far-red spectral energy delivered through a phosphor-converted LED architecture in custom horticultural SSL fixtures has been shown in the lab to deliver increased yield in growing Rouxai red lettuce.

     

    LED-manufacturer Lumileds has released the results of recent horticultural LED lighting research conducted at the Lighting Enabled Systems and Applications (LESA) laboratory located at Rensselaer Polytechnic Institute (RPI). The research conducted by senior research scientist Tessa Pocock revealed that the SunPlus horticulturally-targeted LEDs, and in particular phosphor-converted components, could deliver benefits in yield and nutritional value relative to mixes of monochromatic RGB (red, green, and blue) LEDs. The work focused on yield of the red lettuce cultivar knows as Rouxai and used a horticultural lighting arrangement similar to what might be found in a vertical farm.

    Lumileds announced the SunPlus family in the fall of 2016 including both phosphor-converted and monochromatic components that span mid- and high-power packages. Among the notable members of the family are the phosphor-converted purple LEDs that are manufactured by using red phosphor on a blue emitter. The lime-green LEDs in the family are also phosphor-converted designs. Lumileds recently added a chip-on-board (COB) purple LED to the SunPlus family. The SunPlus LEDs along with horticulturally-targeted LEDs from Seoul Semiconductor, Osram Opto Semiconductors, and Cree were on display at our recent Horticultural Lighting Conference.

    LUXEON's New Products to SunPlus Series for Horticulture

    Lumileds recently introduced three new products in its LUXEON SunPlus Series of award winning LEDs for horticulture lighting. The LUXEON SunPlus Series is the only line of LEDs on the market to be 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 new LUXEON SunPlus CoB Line, available in Purple, is designed for greenhouse applications where attaining high PPF and fast time to market are top priorities.

    CIE Research Strategy in Metrology for Advanced Photometric and Radiometric Devices

    Photometric devices are devices that measure optical radiation and which are designed with a very specific spectral response. Most commonly, illuminance meters and luminance meters are used to measure the illuminance and luminance distributions in the field. These are relatively simple devices, characterized by a specific input optics according to the required task and a filter to make the spectral response of the instrument match the spectral luminous efficiency function of the human eye (typically V(λ) for photopic vision).

    Extra Flat LED Luminaires from LEDVANCE for Recessed or Surface Mounting

    LEDVANCE is extending its portfolio for electrical wholesalers with the third wave of ready-to-use LED luminaires for professional users, including extremely flat versions for walls and ceilings. The Downlight Slim family, for example, is intended above all for narrow spaces such as suspended ceilings. It also offers particularly simple and flexible installation and excellent energy efficiency. That applies also to the narrow and especially robust Surface Compact IK10 luminaire for surface mounting which is ideal for heavily frequented stairwells and public buildings. The luminaires go on sale using the LEDVANCE brand.

    Ams Adds Tristimulus Sensor with Added Blue Spectrum Channels for HCL and SSL Applications

    ams has announced the AS7264N tristimulus sensor for intelligent and tunable LED-based lighting products, and further adds input channels for measuring blue spectral energy at two wavelengths. The company believes that the new sensor will serve both in smart sensors that communicate human-centric lighting (HCL) data to building or lighting management systems, and in solid-state lighting (SSL) luminaires that deliver precise recipes of lighting for health and wellbeing.

    Safety & Security Benefits Of Outdoor Lighting

    Outdoor lighting plays a vital role in ensuring the safety and security of public places, streets, pathways, and walkways. To ensure the safety and security of these places, it is necessary to use the right lamps and appropriate fixtures with proper luminance. It also becomes necessary for lighting systems to follow the lighting standards and guidelines to ensure the safety of people, property, and public spaces. Outdoor lighting system is a prominent requirement for applications such as highways, roadways, airport perimeters, architectures, and other public places. LEDs are increasingly implemented in the outdoor lighting application to control the growing energy consumption of lights. Most countries such as the US, the UK, and Germany are replacing their conventional streetlight lamps with advanced LED lights and luminaires.
