Abstract: A showcase member of a glass showcase, the showcase member including a first portion having a plurality of apertures, a light emitting diode (LED) module positioned at one or more of the plurality of apertures and mounted to the showcase member, and a wiring harness electrically connected to the LED module, and configured to electrically connect the LED module to an LED driver circuit. The showcase member can include a second portion integral to the first portion and having tapers forming light shields protruding from the showcase member.

Abstract: A ceramic arc body includes a main body having a chamber. A leg extends from the main body and has an internal opening therethrough that communicates with the chamber. An electrically non-conductive seal member is received in the leg opening. A tapered internal surface abuttingly engages the seal member and provides for centering of the seal member relative to the leg. A separate tapering region, shoulder, or stop surface limits insertion of the seal member into the leg opening for precision location of the seal member, and in another embodiment, a single continuous taper inside the leg cooperates with a tapered seal member for both centering and precision insertion of the seal member into the leg. In another embodiment, a hybrid electrode is employed where one portion of the hybrid electrode is electrically non-conductive and a second portion of the electrode is electrically conductive.

Abstract: An electrodeless or induction ceramic HID lamp includes a ceramic arc body having a generally spheroidal portion enclosing a discharge chamber and an induction coil received around a perimeter portion of the spheroidal portion. At least one leg extends from the spheroidal portion of the arc body. A mounting structure connects the arc body to the surrounding lamp assembly. In one arrangement, a mounting tube is received over at least a portion of the leg, and may further include a light transmissive shroud that also abuts with the induction coil to precisely locate the arc body relative to the coil. In another arrangement, first and second mounting members extend from spaced locations of the arc body, either as pins or legs extending from the spheroidal portion, or radially extending legs from an equatorial portion of the arc body.

Abstract: Life of a starting conductor or coil in an induction lamp is significantly improved with the present disclosure. A mechanical support supports the starting coil adjacent the arc body of the lamp and has features that allow the starting coil to mount thereon. The mechanical support may be made of a high temperature material such as glass, quartz, or ceramic so that light from the lamp is not blocked. In another embodiment, the starting conductor is protected from oxidation by fully encasing the starting conductor within the high temperature material. In still another embodiment, a thin coating of a high temperature material that may or may not be light transmissive could be used as an alternative manner of support.
