    • An ignition circuit and method, as may be used for igniting a gas discharge lamp, are provided. The circuit includes a voltage multiplier circuit connected to receive a signal corresponding to a DC bus voltage level from a rectifier circuit. The voltage multiplier circuit includes first and second voltage storing circuits configured to each respectively store a voltage level corresponding to a first multiple of the DC bus voltage level (e.g., at least twice the DC bus voltage level). The voltage multiplier circuit further includes a peak voltage holding circuit connected to the first and second voltage storing circuits to accumulate a voltage level corresponding to a second multiple of the DC bus voltage level (e.g., at least four times the DC bus voltage level). The circuit further includes an ignition module having a transformer selectively connected by way of a switch to the voltage multiplier circuit through a primary winding to receive the voltage accumulated at the peak voltage holding circuit, and thereby generate an ignition pulse voltage applied to the lamp through a secondary winding of the transformer.
    • 提供了可以用于点燃气体放电灯的点火电路和方法。 电路包括一个电压倍增器电路,连接成从整流电路接收对应于直流总线电压电平的信号。 电压倍增器电路包括第一和第二电压存储电路,其被配置为分别存储与DC总线电压电平的第一倍数相对应的电压电平(例如,至少是DC总线电压电平的两倍)。 电压倍增器电路还包括连接到第一和第二电压存储电路的峰值电压保持电路,以累积与DC总线电压电平的第二倍数相对应的电压电平(例如,至少是DC总线电压电平的四倍)。 该电路还包括点火模块,其具有通过初级绕组选择性地连接到电压倍增器电路的变压器,以接收在峰值电压保持电路处积累的电压,从而产生施加到灯的点火脉冲电压 变压器的次级绕组。

    • An electrodeless or induction ceramic HID lamp includes a ceramic arc body having a generally spheroidal portion enclosing a discharge chamber and an induction coil received around a perimeter portion of the spheroidal portion. At least one leg extends from the spheroidal portion of the arc body. A mounting structure connects the arc body to the surrounding lamp assembly. In one arrangement, a mounting tube is received over at least a portion of the leg, and may further include a light transmissive shroud that also abuts with the induction coil to precisely locate the arc body relative to the coil. In another arrangement, first and second mounting members extend from spaced locations of the arc body, either as pins or legs extending from the spheroidal portion, or radially extending legs from an equatorial portion of the arc body. In still another arrangement, a ceramic mounting member extends from the arc body and includes a thin peripheral rim having spaced ridges to engage spaced locations of the induction coil.
    • 无电极或感应陶瓷HID灯包括陶瓷弧体,其具有围绕放电室的大致球形部分和围绕球形部分的周边部分接收的感应线圈。 至少一条腿从弧形体的球形部分延伸。 安装结构将弧体连接到周围的灯组件。 在一种布置中,安装管被容纳在腿部的至少一部分上,并且还可以包括透光护罩,其还与感应线圈邻接以相对于线圈精确定位弧形体。 在另一种布置中,第一和第二安装构件从弧形体的间隔位置延伸,或者作为从球形部分延伸的销或腿,或者从弧体的赤道部分的径向延伸的腿延伸。 在另一种布置中,陶瓷安装构件从弧形体延伸并且包括具有间隔开的脊的薄周边边缘,以接合感应线圈的间隔位置。
