    摘要： LED-based lighting apparatus and assembly methods in which mechanical and/or thermal coupling between respective components is accomplished via a transfer of force from one component to another. In one example, a multiple-LED assembly is disposed in thermal communication with a heat sink that forms part of a housing. A primary optical element situated within a pressure-transfer member is disposed above and optically aligned with each LED. A shared secondary optical facility forming another part of the housing is disposed above and compressively coupled to the pressure-transfer members. A force exerted by the second optical facility is transferred via the pressure-transfer members so as to press the LED assembly toward the heat sink, thereby facilitating heat transfer. In one aspect, the LED assembly is secured in the housing without the need for adhesives. In another aspect, the secondary optical facility does not directly exert pressure onto any primary optical element, thereby reducing optical misalignment.

    摘要： A drill bit assembly having an electrically isolated gap joint for electromagnetic telemetry comprises a drill bit, a pin body, an electrically insulating gap joint therebetween, and an electrical conductor extending across the gap joint. The bit head has a cutting end and an opposite connecting end with an engagement section. The pin body has a tubular body with an axial bore therethrough, and comprises a connecting end with an engagement section. The pin body connecting end is connected to the bit head connecting end such that the engagement sections overlap. The electrically insulating gap joint fills an annular gap between the bit head and pin body engagement sections such that the bit head and pin body are mechanically connected together at the connecting ends but are electrically separated. The electrical conductor has one end electrically contacting one of the bit head and pin body, and the other end communicable with electronics equipment.
