Lumileds first releases LED chip products for plant lighting applications

Lumileds introduces the LUXEON SunPlus plant lighting family of LED chips that incorporate photosynthesis photon flux (PPF) to ensure that plant growth lamps can be systematically designed to provide specific wavelengths for greenhouses, vertical farms and other plant growth applications.

Lumileds released the first plant lighting line in the product line: LUXEON SunPlus. Provides the specific wavelength illumination required for plant lighting. According to the rapid expansion of the world's population and the increasing number of residents in the city, it is a problem for the entire horticultural industry to allow more food to be properly used in indoor spaces. At the same time, indoor vertical cultivation can save about 90% of water resources at the same time.

The LUXEON SunPlus 20 Series is suitable for use in greenhouse cultivation, especially in the auxiliary mode of the patio light, which provides 24 hours a day and a full year of illumination. Farmers can develop a single illumination scheme using specific wavelengths, such as blue light (420-480 nm) and red light (620-670 nm). Or use multiple illumination schemes, that is, with multiple LEDs to form the ideal light output, to match the illumination required by the different growth stages of the plant, such as different lighting requirements during the stages of sowing, germination, growth and flowering. The LUXEON SunPlus 20 Series consists of 2.0x2.0mm high power LEDs including blue (440-460nm), deep red (655-675nm), far red (720-750nm), green (broad spectrum) and cool white.

Lumil Acea, senior manager of career development at Lumileds, said: "Lumileds exclusively classifies plant LED chips according to photosynthesis photon flux and wavelength, which means lighting designers can clearly understand the wavelength of selected lamps and design the most suitable lamps for different plants. The SunPlus 20 Series features a high-power PPF that provides a high-power lighting solution. At the same time, the same focal length of the LED chip also provides more efficient illumination."

Vertical farms use multi-layered growth trays, and the required illumination is usually a consistent, high-resolution lighting system. The LUXEON SunPLUS35 series consists of blue (440-460nm), 3.5x3.5mm purple medium power LED chips in cyan, white and three different colors. Lumileds' violet LEDs use highly efficient blue and red phosphors to create a highly consistent light effect for continued crop growth.

Lumileds' violet LED chip series is between 400-700nm. Purple LED (2.5% blue light) stimulates stem growth and flowering, 12.5% ​​blue light purple LED promotes overall growth, and 25% blue LED can stimulate leaf development of leaf. (Source: LED network)
