This process, known as Printoptical Technology, includes the use of a modified wide-format industrial inkjet instrument to print 3D optical structures. The transparent droplets of the UV-cured polymer were sprayed and then cured by a strong UV lamp and integrated at the showerhead.
At the LED professional seminar held in Bregenz, Austria, LUXeXceL demonstrated a new method of designing and manufacturing LED illumination optics, which was subsequently elaborated in various workshops.
The Dutch company LUXeXceL was founded in 2009 and is located in Huss in the Netherlands. It is a company that provides design and add-on manufacturing of photonic services, such as designing and adding Fresnel lenses and stained-glass copies manufactured for use in LED lighting. This process, called Printoptical Technology, was demonstrated at the recent 2013 LED professional seminar. Printoptical Technology includes printing 3D optical structures using a modified wide-format industrial inkjet instrument. The transparent droplets of the UV-cured polymer were sprayed and then cured by a strong UV lamp and integrated at the showerhead.
This process introduced by LUXeXcel Company produces geometric shapes or arbitrary shapes, perhaps including transparent prisms or lenses, full-color 3D graphics and textures. The key element of this technology is a piezoelectric, controllable print head that offers resolutions up to 1400 dpi. Even if the material is discretely precipitated, the final surface is still smooth. This is because there is a time delay during the spraying of the droplets and application of the UV lamp, so that the polymer has a time to flow and the droplets lose their spherical shape.
Market manager Marcode Visser said: “Our company is a change maker in traditional optical products and production methods and has always been at the forefront of developing environmentally friendly and simpler economic solutions.†Optical instruments are designed to enhance light and light distribution; Simplify the performance, design, and manufacture of LED illumination optics; manufacture new products and market introductions. The focus is on the design, short-term prototype and manufacturing process of LED illumination optics.
Printoptical Technology includes the use of proprietary processes to customize lens design services and rapid sample production. From the initial process to later manufacturing with the highest quality features and high-volume customization, it can be 100% efficient. Save on overall system costs due to lower investment costs.
Because products are supplied on demand, there is no need to estimate demand. "This is the world's first and only process, using CAD one-step optical manufacturing to complete optical preparation," deVisser said. Since it is a data model, it is almost a zero tool and requires very little upfront design cost. She further explained: "Our customers prepare the optical element design files they wanted, and then we started creating optical equipment directly from the prepared CAD files."
Combining leading-edge CAD technology with optical design software means less time spent on developing and processing custom design services, enabling faster product launches and meeting customer and market needs. There is no need to create a model, and intermediate steps or post-processing are omitted. Features such as low-cost, on-demand printing, rapid sample forming, and small to medium scale production include the production of Fresnel lenses and free-form lenses, prisms, microstructures, optical layers, full-color graphics, and textured surfaces.
Because Printoptical technology avoids complicated and costly traditional processes - such as injection molding, diamond turning, polishing and grinding - for various optical components, it is called clean technology. The core of this so-called clean technology is the use of UV solutions for the sustainable development, manufacture and processing of optical instruments. This technology does not use hazardous materials, does not produce useless products or void inventory. Thanks to data processing and limited transport activities, CO2 emissions have been reduced, simplifying the supply chain.
All key materials are environmentally-friendly and degradable, and the entire process is a highly efficient and mercury-free process. According to deVisser, UV light solutions can be used in many different applications and are the most environmentally friendly and fastest-growing technologies today. He concluded: “Sustainable management of resources has contributed to sustainable development. As a pioneer in optical innovation, finding the most suitable and fastest new light source for energy saving is a must for us in the future. Things to do."
Highly heat resistant BPA free and FDA approved silicone is safe for coated & non-stick cookware. Silicone Cooking Utensils are stain-resistant. This is because of the non-porous characteristic of silicone. So that it doesn't retain odors or colors when you use it for stirring deep-colored food like tomato-based food products. This also lends the silicone products to easier cleaning or washing. Silicone Cooking Utensils are rubber-like. This makes them very user-friendly when dealing with non-stick surfaces.
