German big company "holding group" to develop compact optical components for lighting

According to reports, OSRAM Opto Semiconductors, together with the Fraunhofer Institute for Applied Optics and Precision Engineering, TEMICON and Continental, has been working hard to develop compact optical components for data visualization or illumination since October 2017. Applications include compact head-up projection displays, ultra-thin camera flashes and selective direct display backlights. According to reports, OSRAM Opto Semiconductors and Fraunhofer Institute for Applied Optics and Precision Engineering, TEMICON and Continental, since 2017 Since October, efforts have been made to develop compact optical components for data visualization or illumination, including compact head-up projection displays, ultra-thin camera flashes, and selective direct display backlighting. The project, titled IBELIVE, is funded by the German Federal Ministry of Education and Research (BMBF) and is expected to last for three years with the goal of developing a particularly compact and versatile optical component. This study is to further reduce the profile of LED chips currently used as light sources. The project covers an entire value-added chain from the development of optical components, mass production to sample application testing. In the course of the project, the alliance will study the flexibility and manufacturing process of the design. Reducing the thickness of the optical components and combining the various optical functions into one microstructure has two benefits: one is to give the designer greater flexibility in integrating the components into the device; the other is to increase energy Efficiency, a greater proportion of the generated light is used in the application. The four participating companies also have a clear division of labor. In addition to coordinating projects, OSRAM Opto Semiconductors is responsible for system concepts and designing two application-based demonstrators while studying installation and testing concepts. Continental is responsible for the design and development of two compact head-up displays with different projection sources. Hybrid diffusers developed for this purpose play a central role in generating images and making efficient use of light. The research here will focus on the image quality perceived by the driver. The Fraunhofer Institute for Applied Optics and Precision Engineering studies the design methods and algorithms of hybrid diffuser optics and the techniques used to generate deterministic surface structures. TEMICON is responsible for coating nanoscale structures using interference lithography and developing injection stamping and forming technology to produce thin double-sided hybrid diffuser optics as a series of products. Dr. Ulrich Streppel of OSRAM Opto Semiconductors said that the IBELIVE research project brings together manufacturers with years of experience in photonic materials. Our findings will strengthen the position of the German industrial power and further demonstrate our innovative power. (

Galvanized Iron Wire

Galvanized Iron Wire is designed to prevent rusting and shiny silver in color. It is solid,durable and extremely versatile, it is widely used by landscapers, craft makers, building and constructions,ribbon manufacturers, jewelers and contractors.Its aversion to rust makes it extremely useful around the shipyard,in the backyard, etc.

Galvanized wire is divided into hot dipped galvanized wire and cold galvanized wire (electro galvanized wire). Galvanized wire has good toughness and flexibility, the maximum amount of zinc can reach 350 g/sqm. With zinc coating thickness, corrosion resistance and other characteristics.

Hot-dipped galvanized iron wire

Hot dipped galvanized wire belongs to the primary wire products of galvanization. Hot dipped galvanized iron wire is made with choice low carbon steel wire, through wire drawing, wire annealing,rust removing and acid washing, zinc plating and coiling. The common sizes of hot dipped galvanized are from 8 gauge to 16 gauge, we also accept smaller or bigger diameter for customers' choices. Hot dipped galvanized wire with firm zinc coating provides strong corrosion resistance and high tensile strength. This kind of wire is widely used for making handicrafts, woven wire mesh, forming fencing mesh, packing products and other daily uses.

Size range: BWG 8-BWG 22

Zinc coat: 40-240g/mÂ²

Tensile strength: 35-70kg/mmÂ²

Elongation: 10%-25%

Packing: 0.1-1000kgs/coil, coil with plastic inside and hessian cloth outside or weave bag outside
