  • Patent number: 10923637
    Abstract: A method of manufacturing a plurality of conversion elements includes providing a first conversion layer on an auxiliary carrier, the first conversion layer converting electromagnetic radiation of a first wavelength range into electromagnetic radiation of a second wavelength range, applying a second conversion layer on the first conversion layer, the second conversion layer converting electromagnetic radiation of the first wavelength range into electromagnetic radiation of a third wavelength range, and separating the generated layer stack such that a plurality of conversion elements are generated, wherein each conversion element includes at least one first converting region having material of the first conversion layer, each conversion element includes at least one second converting region having material of the second conversion layer, and the converting regions are arranged laterally side by side.

  • Patent number: 9341137
    Abstract: The present invention relates to a piston (10) for an internal combustion engine, comprising a piston head (11) and a piston skirt (16), with a cooling channel (15) arranged in the piston head (11) and with at least one bore (17) opening into the cooling channel (15), a conduit (18) for a cooling oil jet (A) being housed in the bore. According to the invention, a jet divider (19) is arranged at the first free end (18a) of the conduit (18) and, in the area of the second free end (18b) of the conduit (18), the outer lateral surface of conduit (18) has a contact surface (24) that lies, secured against torsion, against an inner surface (25) of the piston (10).
