Patent number: 10741946Abstract: A tube used for producing an electrically conductive connection between an electrical conducting element and a printed circuit board of a light fixture. The use of the tube in the printed circuit board makes it possible, due to a corresponding configuration and a region which widens in relation to the longitudinal direction, that the tube can be connected to the printed circuit board or is held thereby and can be soldered. Additionally, the configuration or widened portion prevents soldering agent from penetrating into the tube, so that a wire for voltage supply can then be introduced into the tube and can be connected thereto by deformation. As a result, an automatic and reliable method is made possible, so that a cost saving is produced.Type: GrantFiled: July 11, 2018Date of Patent: August 11, 2020Assignee: LEDVANCE GMBHInventors: Anton Joerg, Matthias Kellner, Thomas Klafta, Wolfgang Seitz, Christoph Steidl, Marcel Vuc

Patent number: 9170499Abstract: The disclosure relates to an illumination system of a microlithographic projection exposure apparatus. The illumination system can include a depolarizer which in conjunction with a light mixing system disposed downstream in the light propagation direction at least partially causes effective depolarization of polarized light impinging on the depolarizer. The illumination system can also include a microlens array which is arranged upstream of the light mixing system in the light propagation direction. The microlens array can include a plurality of microlenses arranged with a periodicity. The depolarizer can be configured so that a contribution afforded by interaction of the depolarizer with the periodicity of the microlens array to a residual polarization distribution occurring in a pupil plane arranged downstream of the microlens array in the light propagation direction has a maximum degree of polarization of not more than 5%.Type: GrantFiled: December 8, 2014Date of Patent: October 27, 2015Assignee: Carl Zeiss SMT GmbHInventors: Damian Fiolka, Manfred Maul, Markus Schwab, Wolfgang Seitz, Olaf Dittmann
