  • Publication number: 20210063625
    Abstract: A light source with a linear appearance is provided. The light source has a flexible light guide that has a homogeneous light emission with high luminance and a emitting light guide. The light emitting guide has a core, in which at least one soul extends, and a transparent cladding that surrounds the core. The core and the cladding are formed from transparent plastic. The core has a higher index of refraction than the cladding. The soul is light-deflecting, light-reflecting, or light-scattering so as to scatter light guided in the light guide and to emit the light through the cladding toward the outside. The soul has a scattering length that is at most twice as large as a maximum cross-sectional dimension of the soul.

  • Publication number: 20210063624
    Abstract: A flexible light guide that has a homogeneous light emission with high luminance is provided. The flexible light guide is provided by a side-emitting light guide. The side-emitting light guide includes a light-guiding fiber designed as a side-emitting fiber so that light guided in the fiber is scattered out along a longitudinal direction in a distributed manner. The guide also includes a tube that surrounds the fiber. The tube is designed to be light-scattering and translucent so that light emitted from the fiber can traverse the tube with scattering. The tube is surrounded by a cladding. The tube and cladding are made of plastic.

  • Publication number: 20210053313
    Abstract: Disclosed are films and a packaging for gas or vapor decontaminable packaging applications and a method for creating a sterile packaging using the same. These films are particularly useful for sterile storage and transport of objects for medical, pharmaceutical or cosmetic uses, in particular of sterile pharmaceutical primary packaging means, like vials, ampules, syringes, or cartridges. Said film comprises at least a layer of a selectively permeable non-woven, a layer of a punctured film, and an adhesive which can be activated by energy transmission. Optionally it comprises further film layers. The method for creating a sterile packaging comprises the step of hermetically closing the packaging by activating the adhesive thereby making the non-woven impermeable.
