    摘要: A simulated load circuit for measuring the impedance of the arc discharge of an electrodeless discharge lamp of the type having an arc tube and an excitation coil for exciting the arc discharge in an ionizable fill contained therein includes: a secondary coil spaced apart from the excitation coil by a distance which is varied in order to vary the coupling coefficient between the secondary coil and the excitation coil; a fixed load resistance coupled to the secondary coil; and a variable matching network coupled in series or parallel with the load resistance, the impedance of the matching network being varied in order to vary the ratio of reactance to resistance of the load circuit. The distance between the secondary coil and the excitation coil is varied, and the impedance of the matching network is varied, until the input impedance of the load circuit is substantially equivalent to the operating impedance of the lamp. The simulated load circuit is useful for designing and testing ballast circuits for electrodeless discharge lamps and for providing measurements of arc discharge power and excitation coil efficiency.

    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: 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 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.
