摘要： An electrodeless high intensity discharge (HID) lamp having an arc tube, a starting aid, and an outer jacket all integrally formed of fused quartz, includes an excitation circuit for providing RF energy effective for initiating and maintaining a gas discharge within the arc tube. The arc tube is positioned within the outer jacket such that a minimum space exists between the outer jacket and the arc tube thereby allowing the efficient coupling of such RF energy to the arc tube by means of an excitation coil wound in close proximate location to the arc tube. The starting aid is of a substantially smaller dimension than the arc tube thereby allowing for a second spacing to occur above the arc tube. This second spacing is effective for optimum thermal management of heat generated within the outer jacket. The upper end of the outer jacket has an integrally formed annular groove for receiving an annular support member effective for securing the HID lamp to a lighting fixture.

摘要： A gas probe starter for an electrodeless high intensity discharge (HID) lamp includes a fixed starting electrode for coupling a starting voltage to a chamber which is attached to the outer wall of the arc tube and contains a gas. The gas in the starting chamber, which is preferably at a low pressure relative to that of the arc tube fill, is switched between conducting and nonconducting states corresponding to lamp-starting and normal running operation, respectively. To start the lamp, the starting voltage is applied to the starting electrode, causing a discharge current to flow in the gas chamber which, in turn, results in the capacitive coupling of a sufficiently high voltage to the arc tube in order to initiate an arc discharge therein. After the arc discharge is initiated, the starting voltage is substantially reduced so that the discharge current in the starting chamber is extinguished.

摘要： An electrodeless discharge lamp comprising an arc tube constructed of a light-transmissive material. An exciting structure surrounds the arc tube and is energizable with radio frequency current to develop an arc discharge. A reflective coating of non-conducting insulating material is disposed on the arc tube wall and is located to reflect light from the arc discharge through the arc tube. The reflective coating and the uncoated portion of the arc tube wall are surrounded by the exciting structure so that light from the arc discharge may reach the reflective coating without blockage by the exciting structure and, following reflection by the coating, travel through the uncoated portion of the arc tube wall.

摘要： A method and apparatus for assembling a ceramic metal halide high intensity discharge (HID) lamp is disclosed. The apparatus includes a base adapted to receive a ceramic arc tube body, a movable gauge arm having a first portion contacting an end surface of the arc tube body, an electrode holder for supporting an electrode in contact with a second portion of the gauge arm, and a crimper for securing a stop to the electrode at a position determined by the extent of movement of the gauge arm. The apparatus permits stops to be secured to electrodes, either simultaneously or sequentially, thereby correcting for a length deviation of the arc tube body. As a result, half of the required correction is made on each electrode. Since both electrodes are set to the same insertion length, an arc gap is inherently centered in the arc tube body during assembly.

摘要： An arc stabilization arrangement for a discharge lamp having a light transmissive arc tube containing a fill of gas excitable to a discharge state upon introduction thereto of a drive signal having a predetermined frequency associated therewith, includes a modulating arrangement effective for providing a modulating signal which is imposed onto the drive signal. The modulating signal has a frequency associated therewith which approximates the acoustic resonance of the gases within the fill, such modulating signal frequency being less than the frequency of the drive signal. In one embodiment of the invention the modulating arrangement is an amplitude modulating scheme effective such that a modulating amplitude of greater than about 5% of the amplitude of the drive signal is achieved. In yet a further implementation of the present invention, the frequency of the modulating signal is swept about a range of frequencies so that a varying acoustic resonance frequency can be encompassed by the modulating signal.

摘要： A lamp-to-light guide coupling arrangement includes an electrodeless high intensity discharge lamp comprising an arc tube with an ionizable fill, and an excitation circuit for electrically exciting the ionizable fill to induce therein a light-producing arc discharge. The coupling arrangement further includes a coupling device comprising a generally tubular, hollow body that has an inlet end for receiving light from the arc discharge and a larger, outlet end. The coupling device further comprises an interiorly directed reflector on a surface of the hollow body for reflecting visible light. Such coupling device is shaped so as to receive light at one solid angle over an area of the inlet end and to transmit light at a smaller solid angle but over a larger area of the outlet end. The coupling device is preferably formed from dielectric material. The reflector preferably comprises a refractory optical interference filter.
