Photometric Test Results

Photometric Test Results

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.

Remote Phosphors in Lighting Applications

Remote Phosphors in Lighting Applications

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.

Solar Decathlon

Solar Decathlon

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.

RSLEDIP68 Encapsulation and Immersion Testing

RSLEDIP68 Encapsulation and Immersion Testing

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.

Photobiology in Agriculture

Photobiology in Agriculture

Photobiology is the study of light and its effect on living things. There has been a great deal of study on photobiology in the area of agriculture. The interest continues to grow because the science is becoming more refined and the marketplace is developing. Some random notes and an initial Nemalux fixture spectra is shown below. McCree Curve: K. J. McCree (1970) studied and developed the action spectrum, absorption and quantum yield curves of photosynthesis in crop plants. The action spectrum is commonly known as the McCree Curve. McCree curve shows the relative photosynthesis response in the between 400-700 nm (commonly known as photosynthetically active region or PAR) for plants growth. This is also known as the generalized PAR curve. McCree also showed the relative quantum yield and relative absorption for 400-700nm region. This work has been the basis of all of the researches that followed until now.

Photobiology: Safety and Productivity

Photobiology is the study of light and its effect on living things. There has been a great deal of study on photobiology in the area of agriculture. However, its application in the oil & gas environment is a new field. It is a niche market for those companies like Nemalux that have the expertise to engineer lighting systems that enhance operations and safety in the energy sector. An oil & gas operation runs on a 24 hour rotation. It is a rhythm that is dictated by the market demand for the product. Employees on the same site are not immune to the demands of the market. Twelve hour shifts and rotating shift work is part and parcel in the oil & gas industry. It’s a potentially explosive environment where serious accidents can occur. Statistically, most oil rig accidents occur between the hours of 8:00pm and 10pm. The principal cause: worker fatigue.
