Problems solved by technology

Obviously, this results in a significant cost for the instant start system to modify the standard design by providing insulation for higher ignition voltages, providing high voltage rating lamp bases and lamp caps, and using the high voltage cables required to deliver the ignition pulse
Therefore, a hot retrigger ignition pulse of about 25 kV causes more serious EMI interference and requires additional work to shield the system

Embodiment Construction

[0024] figure 1 A conventional lamp socket housing or base 100 is shown, typically for a high intensity discharge (HID) lamp (not shown), which is removably retained in the socket housing. More particularly, the receptacle housing includes a first power cable 102 and a second power cable 104 having respective first ends 106 and 108 connected to an associated power source (not shown) . When the lamp assembly is intended for instant start thermal retrigger applications, the power cables 102, 104 are relatively heavy duty high voltage cables with substantial insulation to carry voltages on the order of tens of thousands of volts to supply the lamp housed in the socket housing. A volt ignition pulse of approximately twenty-five kilovolts (25kV) to thirty kilovolts (30kV). Thus, the power cables run from the power source, which includes a ballast (not shown) and also includes a transformer, which steps up the voltage from levels of several hundred volts (less than 1200 volts) to ...

Abstract

A lamp assembly includes a housing that selectively receives a removable, plug-in high intensity discharge (HID) lamp. A transformer and electrical circuit are received in the housing for providing an instant start, hot re-strike ignition of the lamp at less than 25 kilovolts. 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

Background technique [0001] This application is related to a commonly owned co-pending application entitled "IGNITER INTEGRATED LAMP SOCKET FOR HOT RE-STRIKE OF HIGH INTENSITY DISCHARGE LAMP" [Attorney No. 220932], filed concurrently with this suit. [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 thermal re-strike of the lamp is desired. It is particularly suitable for use in HID lamps, which are replaceable with respect to the socket assembly, although it should be understood that selected aspects are applicable in related applications. [0003] In instant start thermal retrigger applications, the ignition voltage is typically on the order of tens of thousands of volts (eg, 25-30 kilovolts). The high voltage requires the use of high voltage cables from the igniter to the lamp socket and thus better electrical insulation. And this increases...
