Problems solved by technology

Obviously, this would result in significant cost for the instant start system, so that the standard design would be modified in such a way as to provide insulation for higher ignition voltages, provide high voltage rated lamp bases and lamp sockets, and also use the high voltage cables
So a hot restart firing pulse of about 25 kV caused much more severe EMI interference and required additional effort to shield the system

Embodiment Construction

[0029] figure 1 Shown is a conventional lamp socket housing or base 100 typically used with a high intensity discharge (HID) lamp (not shown) in which the high intensity discharge lamp is removably retained. More specifically, the receptacle housing includes a first power cable 102 and a second power cable 104 having respective first ends 106, 108 that connect to an associated power source (not shown). Where the lamp assembly is intended for instant-start, hot-restart applications, the power cables 102, 104 are relatively high-power, high-voltage cables that are sufficiently insulated to transmit about tens of thousands of Volts and thus provide a volt ignition pulse of approximately twenty-five kilovolts (25kV) to thirty kilovolts (30kV) to the lamp received in the socket housing. Thus, the power cables run from a source that includes a ballast (not shown) and also a transformer that steps up the voltage from a level of a few hundred volts (below 1200 volts) to 25kV to 30kV....

Abstract

A lamp assembly includes a housing (200) that selectively receives a removable, plug-in high intensity discharge (HID) lamp (240). A transformer (216) and electrical circuit (214) are received in the housing for providing an instant start, hot re-strike ignition of the lamp at less than 25 kilo volts. A circuit for an instant start, hot re-strike of an HID lamp supplies an ignition voltage to the HID lamp that includes pulses having an amplitude of less than 25 kilovolts and a frequency ranging from approximately 20 hertz to approximately 500 hertz. Preferably, the frequency is greater than 100 hertz, more preferably the frequency is approximately 150 hertz. The amplitude of pulses are preferably less than approximately 15 kilovolts, and more preferably approximately 8-10 kilovolts. The pulse width is approximately 200 nanoseconds and the peaks of the pulses are periodic with a period of approximately 2 milliseconds.

Description

technical field [0001] THIS APPLICATION IS RELATED TO "LOW IGNITIONVOLTAGE INSTANT START FOR HOT RE-STRIKE OF HIGH INTENSITY DISCHARGE LAMP (LOW IGNITION VOLTAGE INSTANT START FOR HOT RE-STRIKE OF HIGH INTENSITY DISCHARGE LAMP)," filed concurrently with this application [Attorney Docket No. 233695], a co-owned, co-pending application. [0002] The present disclosure relates to discharge lamps, and more particularly, to high intensity discharge (HID) lamps, such as ceramic metal halide (CMH) lamps, where instant start, hot restart of the lamp is desired. It has particular application in HID lamps that are replaceable with respect to the socket assembly, but it will be appreciated that selected aspects may be applicable in related uses. Background technique [0003] In instant start, hot restart applications, the ignition voltage is typically on the order of tens of kilovolts (eg, 25-30 kilovolts). This high voltage necessitates the use of high voltage cables from the ignite...
