Abstract: A generally planar, flexible light source assembly or OLED device includes a generally planar, flexible light emitting member having opposite first and second surfaces. An impermeable backsheet is disposed along the first surface of the light emitting surface and includes a conductive portion and an opening through the backsheet. A conductive tab or cover is received over the opening, and an insulator is disposed between the tab cover and the opening to mitigate the risk of electrical contact between the components. The insulator can be precut washer-like members or an applied insulating material situated between the conductive components of the light source assembly that pose a potential for shorting. Using tabs with burr-free edges also mitigates against the risk of electrical shorting.

Abstract: An arc lamp comprises a single edge-to-edge cathode support strut on which the cathode is mounted with an end slot. Such makes heat and thermal stress loading on the assembly symmetrical over operational time, and arc tip wander from the anode center is practically eliminated. Nine component parts that are brought together in only three brazes and one TIG-weld to result in a finished product. An anode assembly is brazed with the rest of a body sub-assembly in one step instead of two. A single-bar cathode-support strut is brazed together as one step. A window flange and a sapphire output window are brazed together with the product of the strut braze step in a mounted-cathode-braze step. A copper-tube fill tubulation, a kovar sleeve, a ceramic reflector body, an anode flange, and a tungsten anode are all brazed together in a “body-braze” step. The products of the mounted-cathode-braze step and body-braze step are tungsten-inert-gas (TIG) welded together in a final welding step.
