English 繁體 简体 PURA-Panel Air-Purifying LED Panel PACO NANOTECH™ filter with UV-C LED Destroys 99.99% of bacteria, viruses and inactivates SARS-CoV-2 PURA-Panel illuminates the space and, in the meantime, provides extraordinary air purifying efficiency while accommodating the sanitizing area’s size, thanks to the sophisticated filtration system. The foam pre-filter traps airborne contaminants and the patented PACO NANOTECH™ filter carries out a purification that eliminates the remaining bacteria, viruses, VOCs (Volatile organic compounds) and odors. Then the air passes through the UV-C light to destruct the DNA and RNA of the micro-organisms, stopping them from reproducing. Finally, the fan outlet releases only fresh and clean air. Pura Panel can suit different ceiling sizes to suit different geographic regions (600x600mm, 625x625mm, 2ftx2ft) without affecting other component sizes. Only the outer flange size will change

Industrial Design Heat Sink Design on Shovel Tooth Technology A well-designed thermal management system is critical for the longevity of all LED products, especially when developing high-power LED lighting products such as street light cities and the 1200W high-power grow light for greenhouse. Our industrial designers work closely with the R&D team to design a highly reliable thermal management module, by taking serious account in minimizing weight, reduced production cost, and maximizing the efficiency of heat dissipation. Fins are connected to the heat sink body, directly, no interface media Without interfacing medium, high long term reliability Shovel tooth technology can handle thinner fins, higher heat sinking efficiency Spacing of fins can also be adjusted flexibly, strong adaptability tools Short turn around time 热管技术 最大化热性能和亮度 能应付极大热密度的设计 增加产品寿命 制作细小，高效，乎合特定形状的散热器 : 如AR111等防眩光产品符合预定的尺寸和成本目标 局部去绝缘层铅基板 高功率 LED 直接金属对金属热传导 中轴是热管，发挥最佳散热效果 Plastic Housing Technology Simplified mechanical structure Minimum mechanical post processing (low cost) Electrical insulation (non-accessible metal) Suitable for high voltage LED and non-insulated PSU Light weight Elegant Streamlined Design for Street Lighting 创新的弧形玻璃盖设计，方便清洁 精密的平行鳍片和光滑顶面，更利于自然清洁 质轻的单向压铸外壳（9.9千克），提高安装安全 高效的散热设计保证了产品的使用寿命

The latest LED grow-light solution by Light Engine has been deployed in various trials farms within America. According to the farm report, the new grow-light solution has increased the yield up to 72%, with different installation methods.

The survey collected data for hemp grown in the open and hemp under protection. Planted area for industrial hemp cultivated in the open for all utilizations in the United States totaled 54,152 acres. The area harvested for all utilizations totaled 33,480 acres. The value of U.S. hemp production in the open totaled $712 million. The value of output for hemp grown under protection in the United States totaled $112 million. The area under protection totaled 15.6 million square feet. With this trend and massive demand for hemp, growers shift their greenhouse and indoor farms to a commercial hemp production base. As the yields and quality of hemp growth are heavily influenced by light intensity – having supplemental or high-quality sole-source lighting systems is critical to maintaining plant health and maximizing cannabinoids content. Light Engine has developed the latest CabLED Grow Light System to support year-round hemp production. In mid-2021, Light Engine has deployed the CabLED grow system in four trial farms, with three indoor farms in Michigan, California, and Washington, respectively, and one greenhouse in Colorado. The system was built with the flexible grow light strip fixed on every edge of the rack. The racks are situated between the hemp, providing a 360-degree light source to favor its growth. The report shows a significant yield increase, with 23%, 31%, and 72% increment in the indoor farms located in California, Washington, and Michigan, respectively, while the result in Colorado greenhouse is still under processing. The difference in increase rate is due to the parameter variations from installation methods. Contact us for full report

Customized Spectrum Custom Lighting Spectrum Light color and spectrum is the result of additive color mixing - by varying the relative amounts of each color input, the resulting SPD and chromaticity can be manipulated. A precise custom light spectrum can help optimizing the result in different activities, such as increase growth and reproduction in horticulture and livestock industry, or enhance human health and concentration. Agricultural Lighting Wavelength of about 450 nm, blue light promote plant germination, and succulent plants growing. The relationship between spectrum and plant growth Wavelength of about 630 nm, red light promote plant photosynthesis, blooming, flowering and results. Aquarium Lighting RGB color mixing technology offers a range of multiple solutions for different application such as: aquariums, aqua plants, coral reefs, ornamental fish tanks, fish ponds, etc. 想了解更多关于 未来的种植市场吗？ Contact us Human-Centric Light Since different user segments enjoy different daily routines, thus the objectives of circadian light should be varied.

Lighting is an essential element for plant growth. The most commonly used spectrum includes red (R), white (W), and blue (B) lights that are highly active for photosynthesis. The effect of R, W and B spectral components on plant physiology and biochemistry and resource use efficiency were studied during an experiment in a deep cycle hydroponic tray system.

The effect of R, W and B spectral components on plant physiology and biochemistry and resource use efficiency were studied during a experiment in a deep cycle hydroponic tray system. The initial experiments were simply to identify the growth characteristics of different species of plants when exposed to the appropriate wavelength for photosynthesis. The study aimed to identify which light format best suited which variety of plant to produce the highest yield. Essentially this was about identifying a ‘Goldilocks’ zone for optimal plant performance. In four experiments in relatively controlled conditions (PPFD = 215 μmol m−2 s−1, daylength 18hrs). LED lighting increased yield (1.8 folds) and energy use efficiency (2.8 folds) as compared with fluorescent lamps. Adoption of MTRWB (RB = 3) maximised yield (by 2 folds as compared with TTWR 1.5 folds), also increasing leaf chlorophyll and flavonoids concentrations and the uptake of nitrogen, phosphorus, potassium and magnesium. As the red portion of the spectrum increased, photosystem II quantum efficiency decreased but transpiration decreased more rapidly, resulting in increased water use efficiency up to RWB (75 g fW L−1 H2O). The transpiration decrease was accompanied by lower stomatal conductance, which was associated to lower stomatal density, despite an increased stomatal size. Both energy and land surface use efficiency were highest at RWB. We hereby suggest a RWB ratio of R =70%, B=25% with nominal use of W=5% (to view the plant colour and density) for most effective plant cultivation, however further experimentation is required to find the optimal balance and ratio of this LED configuration with respect to density of the overall wavelength. By measuring the LED wavelength in different sections of the tray over the most productive plant growth showing the highest stomatal density, leaf growth and overall weight it was possible to identify the optimal light balance. The LED strip configuration resulted in different plant growth over individual plant species allowing us to record specific growth in that region of the tray. Contact us for full report
