Patent number: 10408985Abstract: A lighting device (30) comprises a side-light light guide 1? located in a support (2) that has an elongate opening for the passage of light emitted by the light guide. The support (20) is shaped to provide contact edges (24) and the only physical engagement between the support and the light guide is along those contact edges. The support also has planar surfaces internal positioned adjacent, and parallel to, planar surfaces (15) in the light guide to retain the light guide in the required orientation in the support. To enhance the flexibility of the support, in some embodiments only part of the support is continuous along the whole length of the support.Type: GrantFiled: February 11, 2014Date of Patent: September 10, 2019Assignee: 3M Innovative Properties CompanyInventors: David M. Rudek, Joerg R. Purfuerst, Hans-Michael Vogt

Publication number: 20100142226Abstract: A lighting device comprises a side-light light guide (12) located in a support (13). To facilitate the location of the light guide (12) in the support (13) and ensure its retention in a predetermined orientation, at least one location feature (11) is formed on/in the light guide for engagement by the support. Advantageously, the/each location feature (11) has no substantial effect on the light output of the light guide through its light-emitting region (18).Type: ApplicationFiled: August 10, 2007Publication date: June 10, 2010Applicant: 3M INNOVATIVE PROPERTIES COMPANYInventors: Hans-Michael Vogt, Mark Pilhofer, Christoph Michel, Carsten Sambraus, Norbert Schiffer, Ulrich Kunze, Joachim C.R.
