摘要： A ceramic arctube preferably for a high pressure discharge lamp. The ceramic arctube can have an anti-reflection interference coating on the outside or inside surface of the bulb section of the arctube. The outside and/or inside surface of the outer wall of the bulb section of the arctube can be substantially spherical to increase efficiency. The wall thickness of the outer wall of the bulb section can be shaped to lens rays from the arc toward a preselected region of a retlector optically coupled to the arctube to increase efficiency.

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, multilayer 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： An ignition aid (50, 52, 54, 56) is provided for an HID lamp (20). Particularly the ignition aid includes an electrically conductive coil or coil portions (52, 54) wrapped around selected portions of the arc tube (22) 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 and thereby control the spacing between the arc tube and the shroud. This limits the maximum thermal stress of the arc tube within a desired range.

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 Il and a half cycle time duration T, a current pulse waveform including at least one current pulse with a half cycle mean amplitude 12 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 ceramic arctube for use in a high intensity discharge lamp. The arctube includes a ceramic light transmitting tube which surrounds the arc. The light transmitting tube has two or more features selected from the group consisting of (a) an inner diameter less than 2.6 mm, (b) a wall thickness of less than 1.4 mm, (c) an average grain size of greater than 20 microns or less than 5 microns or real in-line transmission (RIT) greater than 20 %, and (d) an inner surface or outer surface having an Ra value less than 100 nm. These features lead to a smaller apparent size of the arc source and less scattering of light, resulting in improved performance of the arctube in a reflector lamp.
