Zumtobel, a number one worldwide supplier of lighting options for industrial properties, developed its strong AMPHIBIA moisture-proof luminaire for an especially big selection of business functions. The lengthy LED diffuser luminaire lights up factories, logistics facilities, agricultural buildings, parking garages and way more. It’s out there in three variations, tailored to completely different areas of use. Zumtobel produces considered one of these, the AMPHIBIA PM, from PLEXIGLAS® molding compounds, the model polymethyl methacrylate (PMMA) from Röhm. “Our materials meets the excessive requirements wanted for industrial lighting and likewise affords excellent lighting properties,” says Andrea Fruth, Senior Product Supervisor Lighting, Extrusion, Optics within the Molding Compounds enterprise unit of Röhm GmbH.
The identical materials for diffuser and housing
Each the housing and the diffuser of the AMPHIBIA PM are produced from the PLEXIGLAS® Resist zk5BR particular molding compound. It’s the place the flexibility of the extremely clear, impact-resistant materials, which may also be outfitted with diffuser particles for an opalescent look, actually comes into its personal. “Our one-material idea for the housing and diffuser was distinctive when AMPHIBIA was launched. It ensures optimum resistance all through the luminaire’s complete lifespan,” explains Thibaut Escourrou, International Product Supervisor at Zumtobel. The benefit of utilizing the identical materials for all the product is that all the pieces has the identical thermal growth properties. This ensures that the luminaire stays watertight, even when uncovered to important fluctuations in temperature.
However its versatility is simply one of many explanation why Zumtobel selected PLEXIGLAS®. “We worth PLEXIGLAS® Resist zk5BR for its very excessive transparency,” says Escourrou. “PMMA’s excessive UV resistance can also be a bonus for luminaires used open air and in coated out of doors areas, reminiscent of in agricultural settings.” It is because the fabric’s integral UV safety permits PLEXIGLAS® to retain its optical properties completely, with out climate circumstances inflicting it to change into yellow or brittle.
Extraordinary transparency and excessive floor copy accuracy
Zumtobel’s specialists have developed a spread of sunshine situations for the AMPHIBIA collection, tailor-made to numerous room dimensions and ceiling heights. For instance, the luminaire could be outfitted with very slender beam angle optics for illuminating high-shelf logistics facilities. PLEXIGLAS® Resist zk5BR is awfully clear and mixed with its excessive floor copy accuracy in injection molding, the particular molding compound is good for high-precision optical parts like this. Within the AMPHIBIA luminaires, linear microstructures on the backside of the clear cowl information the sunshine to cowl a deep or extensive space, precisely as wanted.
“PMMA is the one actual alternative of fabric on the subject of lighting expertise. It permits us to attain most mild yield and effectivity,” agrees Wolfgang Bechter, International Undertaking Supervisor at Zumtobel. “AMPHIBIA is designed for a lighting period of 100,000 hours, so we place nice significance on selecting the right materials for a protracted lifespan. From this viewpoint, too, PLEXIGLAS® molding compounds from Röhm meet Zumtobel’s high quality requirements.”
Immune to cleansing brokers
The lifespan of business lighting relies upon not solely on the fabric’s resistance, but additionally on the product having the ability to face up to dust and moisture and straightforward to wash. Designer Stefan Ambrosius and his improvement group due to this fact designed AMPHIBIA’s geometry in such a manner that as little dust as potential adheres to it whereas water merely runs off the graceful surfaces and rounded edges. With its extraordinarily strong housing, which retains out all mud and water, AMPHIBIA meets the necessities for the IP66 security class and might face up to even the water jet from a stress cleaner.
The truth that all the luminaire is produced from clear parts additionally has a really sensible cause on the subject of cleansing: “You’ll be able to see from beneath whether or not dust has collected on the highest of the sunshine and must be cleaned. That was one of many buyer’s hygiene necessities,” explains Escourrou. “The PMMA variant affords excellent resistance in opposition to a lot of chemical compounds which are generally utilized in meals processing vegetation, together with cleansing brokers.”
