摘要: A method and system to supply current to a high pressure lamp is provided, the method and system comprising an alternating lamp current waveform with a half cycle mean amplitude I1 and a half cycle time duration T, a current pulse waveform including at least one current pulse with a half cycle mean amplitude I2 and at least one current pulse occurring after the trailing edge of a half cycle of the alternating lamp current, the pulse having a half cycle duration of Tp. These waveforms are combined to generate a current waveform including a current pulse waveform, the current pulse waveform starting after a time delay Td from the trailing edge of a half cycle of the alternating lamp current waveform, the time duration Tp of the at least one current pulse lasting less than the remaining time before the leading edge of the second half cycle of the alternating lamp current waveform. The combined current waveform supplies current to a high pressure lamp and produces a cone shaped tip protrusion which reduces lamp flicker.

摘要: A lamp is provided having an arctube having a light-transmitting envelope. The arctube is surrounded by a gaseous medium confined by a containment envelope such as a hermetic shroud. The gaseous medium is preferably He or H2 or Ne or another gas whose thermal conductivity is greater than that of N2 at 800° C., or a mixture thereof, to help cool the arctube. The inside and/or outside of the shroud may be coated with a diffusion barrier. To help cool the hot spot of the arctube the gap between the shroud and the envelope can be made small, the portion of the shroud wall near the arc can be thickened, the arctube can be offset above the longitudinal axis of the shroud, and the return lead of the arctube can be located between the shroud and the arctube.

摘要: An ignition aid (50, 60, 70, 80, 100, 120, 130, 150, 160, or 170) is provided for an HID lamp (20). Particularly the ignition aid includes an electrically conductive coil or coil portions wrapped around selected portions of the arc tube to act as the ignition aid and lower the breakdown voltage. In other embodiments, starting aids, and particularly one or more turns of the conductive coil or coil portions support the arc tube within an opening of a surrounding shroud (90) and thereby control the spacing between the arc tube (20) and the shroud (90). This limits the maximum thermal stress of the arc tube within a desired range.

摘要: A light weight, bobbinless high voltage transformer and igniter module is provided that meets low-cost and high-reliability requirements for automotive HID products. A printed circuit board (112) serves as a carrier for low voltage electronic components. A high voltage bar core transformer (114) is held in a cradle (130, 130′) that accommodates potting material and has a channel (160) that receives a high voltage wire extending from the transformer for connection with a lead (104) of an HID lamp (100). Thin walls (210, 212) allow the cradle to serve as the cavity for the potting of the transformer. In addition, multi-layer dielectric material is disposed between the primary and secondary windings. Preferably, the primary winding (196) is a strap that covers a large surface area of the secondary winding (192).

摘要: A ballast circuit is suitable for driving a high intensity discharge lamp in at least two power modes including a nominal power mode for driving the high intensity discharge lamp at a nominal power and a reduced power dimming mode for driving the lamp at less than the nominal power. The lamp ballast circuit generates a first alternating current waveform during the nominal power mode and generates a background alternating current waveform in the reduced power mode which is perturbed at intervals by a high intensity pulse which helps to reduce the change in correlated color temperature which would otherwise occur in the dimming mode.
