Abstract: A conversion device includes a carrier body, a conversion body, which is secured on the carrier body, for converting electromagnetic radiation, a conduction track, which is applied on the conversion body, for monitoring the conversion body, and a contact element applied on the carrier body. The contact element has a first layer construction including at least a first contact layer and a second contact layer including mutually different materials. The conduction track has a second layer construction including at least a first conduction layer and a second conduction layer comprising mutually different materials. The contact element is electrically connected to the conduction track. At least one of the first conduction layer or the second conduction layer are electrically conductive and the thickness of said conductive layers is chosen such that an electrical impedance of the conduction track lies in a predetermined range.

Abstract: A reflective laser activated remote phosphor (LARP) package comprising: a phosphor platelet oriented in a first plane defined by an x-y plane; a laser diode (LD) positioned to be offset along the x-axis from the phosphor platelet and above the first plane along a z-axis perpendicular to the x-y plane, the LD comprising: an output facet configured for emitting a laser beam (LB), the LB comprising: a slow axis oriented in a first direction along which the LB diverges at a first angle; and a fast axis oriented in a second direction along which the LB diverges at a second angle greater than the first angle; wherein the LD is oriented such that: the LB is bisected by the phosphor platelet such that the slow axis of the LB lies in an x-z plane and the fast axis of the LB is perpendicular to an x-z plane.
