We have launched a great new product, the AR-GL, it has been designed for harsh locations, extreme water resistance and comes with corrosion protection. Key Features: Thermally managed for maximum longevity; Multiple mounting options; Emits light in the photosynthetic photon ux (PPF) range of plants (400 to 700 nm); ‘Sunlight’ model’s spectum can be tuned based on the crop and lifecyle of the plants; Special powder coating for extreme resistance to chemical attack and aggressive cleaning agents and bio-cides used in food processing industries; Low surface-energy coating and smooth surface textureprevent debris build-up and staining; Vented enclosure ensures long-term reliability; 0-10V Dimming 1%-100%.
An explosion proof lighting fixture indicates that if explosive gas gathers inside the fixture and then explodes, the fixture will contain the explosion. The design of the fixture then, needs to have a “flame path” where the fire is extinguished, but the pressure is released. In the certification process, this is done with different gases and sparkplugs. In some of our research we used hydraulic pressure to test the maximum pressure that a fixture can contain without deforming. This can be a very dangerous process.
We are currently developing a grow light. This fixture is designed to be better at growing and brighter than conventional solutions. The lux to PPFD or lumen to PPF conversion for AR30-H1-WC-WT-GL-AC fixture is much higher than HPS fixture. We have taken our “Food Safe” fixture design and integrated plant lighting. The fixture is sealed, watertight and perfect for large scale growing.
Several companies have heavily patented the use of remote phosphors in lighting applications. Most of these patents are broad enough to cover any LED use of phosphors. Additionally there are numerous application-specific patents out there by a wide range of companies. LEDs Magazine has a good overview article on the patent landscape for remote phosphors here. Cree is asserting a patent on remote phosphor based LED luminaires and bulbs, the rights to which are not automatically granted with the purchase of Cree royal blue LEDs. Cree’s licensing program is detailed here. Intematix is also asserting rights to a number of patents on remote phosphor designs, their list of patents and patent applications can be found here. It appears that use of the Intematix Chromalit line of remote phosphor products includes right-to-use, and that Intematix will provide legal defense in event of a lawsuit based on rights to the remote phosphor technology. It is not clear whether this support is provided for use of raw phosphors coated by Nemalux. Nemalux will need to ensure that it carries out a patent search and assesses right-to-use prior to product launch for any remote phosphor application.
The U.S. Department of Energy Solar Decathlon is a collegiate competition made up of contests that challenge student teams to design and build full-size, solar-powered houses. The winner of the competition is the team that best blends design excellence and smart energy production with innovation, market potential, energy and water efficiency. Simply put, there’s nothing else like it. In 2009, we installed a low voltage distribution system to control the lighting and peripherals in the Alberta/University of Calgary entry. Team Alberta came in 6th place out of 20 contestants.
The initial trial units of a fully sealed RSLED design failed after several weeks in-situ under water at a depth of approximately 3m. Design modifications to the RSLED head and further testing were carried out to enable permanent submersion at depths of up to 4m. Based on internal Nemalux testing, a fully encapsulated RSLED head appears water-tight and suitable for permanent submersion at depths of 4m or less. It should be noted that this is a Nemalux internal IP68 test only, and all units produced in this manner will be CSA or QPS special inspected to general location standards.
