  • Patent number: 8432093
    Abstract: An arc tube light source supported by a discontinuous two-part (top and bottom) frame inside a bulb of an HID lamp is ruggedized to reduce weld breakage under vibration and shock. Each of the top and bottom frames is substantially U-shaped, with the open end of the U-shape being attached by a strap to a pinch of the arc tube. For ruggedization a bracing strap is fixed to, and extends between, two sides of the frame and is welded to a lead wire extending from the pinch. Strength is enhanced if two lead wires extend from the pinch, and the bracing strap is welded to both. Advantageously the two lead wires are sides of a U-shaped wire such as a “U-pin”. Further stabilization may be achieved by using braces attached to both of the top and bottom frames and extended out against surrounding parts of the bulb.

  • Patent number: 8004166
    Abstract: An improved germicidal lamp of the type containing mercury, having a ceramic base, and disposed in, and preventing contact with, a transparent quartz sleeve to prevent formation of a cold spot in the germicidal lamp caused by an undesirable thermal transfer between the lamp and the sleeve and which causes condensation of the mercury at the cold spot in the germicidal lamp. The improvement includes the ceramic base having a circumferential groove therearound, and a thermally insulating ring siting in the circumferential groove of the ceramic base so as to prevent the ceramic base from contacting the sleeve to prevent formation of the cold spot in the germicidal lamp caused by the undesirable thermal transfer between the lamp and the sleeve and prevent the condensation of the mercury at the cold spot in the germicidal lamp.

  • Patent number: 7969074
    Abstract: The invention relates to a mercury-free low pressure discharge lamp with a discharge vessel having an ionizable filling. The surface temperature of the discharge vessel, and thus the temperature of the ionizable filling, can be adjusted at least in some sections such that an emitting substance can produce the radiation required for the excitation of the luminescent substance. The temperature of the fluid is preferably adjusted in a temperature control circuit, using a temperature sensor, a pump and a heating device.
