    • A ballast for an electrodeless discharge lamp includes a high frequency power supply that supplies a high frequency electric power to an induction coil for operating the lamp. A dimmer controller generates a control signal in response to a dimmer command designating a varying dimming ratio. The control signal defines a first period Ton in which the power supply is controlled to apply a coil voltage of a first level V1 to the induction coil for operating the lamp. The first period is followed by a second period Toff in which the power supply is controlled to apply the coil voltage of a second level V2 that is lower than the first level and fails to sustain the lamp. The control signal defines, between the second period and the first period, a starting period Tst in which the coil voltage increases continuously for smooth transition from an off-condition to an on-condition of the lamp.
    • 无电极放电灯的镇流器包括向用于操作灯的感应线圈供给高频电力的高频电源。 调光器控制器响应于指示变化的调光比的调光器命令产生控制信号。 控制信号限定第一时段Ton,其中控制电源以将第一电平V 1的线圈电压施加到用于操作灯的感应线圈。 第一时段之后是第二时段Toff,其中控制电源以施加低于第一电平的第二电平V 2的线圈电压,并且不能维持灯。 控制信号在第二周期和第一周期之间定义起始周期Tst,其中线圈电压连续增加以从灯的关闭状态到状态的平滑过渡。

    • Electrodeless discharge lamp lighting device. Start circuit 19 sweeps operating frequency of resonance circuit 16 from start frequency to end frequency of resonance frequency side through drive circuit 18 and DC/AC conversion circuit 15, and starts electrodeless discharge lamp 13. Control circuit 10 increases or decreases variable power into circuit 18 so that detection current comes to equal prescribed current for shifting the operating frequency to middle range frequency between the start frequency and the end frequency. The prescribed current is set so that the detection voltage in case of the middle range frequency becomes lower than that in case of the end frequency. Capacitor 106 constituting integration circuit starts suppression of operation of circuit 10 when lamp 13 is started, and holds the suppression during at least start mode. Accordingly, it is possible to stably start lamp 13 and control stress on circuit(s) after lamp 13 is successfully started.

    • Very small projections (10-2) are arranged on a mirror surface (10-1) of a mirror (10). The shape of a projection (10-2) is not limited to a circular cone, but it can be a hollow-cylindrical shape, semispherical shape, or square prism shape, and also, it can be a polyhedron with many faces. With a reduction in temperature of the mirror (10), water vapor contained in a gas to be measured condenses on the mirror surface (10-1) of the mirror (10). In this case, because of the very small projections (10-2) on the mirror surface (10-1), the condensation is promoted by the projections (10-2) serving as the cores. This facilitates condensation even at low dew points and improves response. Further, the size of condensation products does not easily vary relative to variation in flow speed of the gas to be measured, and this makes equilibrium of condensation less likely to break, increasing measurement accuracy.
    • 非常小的突起(10-2)布置在反射镜(10)的镜面(10-1)上。 突起(10-2)的形状不限于圆锥形,而是可以是中空圆柱形,半球形或正方形棱镜,并且也可以是具有许多面的多面体。 随着反射镜(10)的温度降低,包含在待测气体中的水蒸气在反射镜(10)的镜面(10-1)上冷凝。 在这种情况下,由于镜面(10-1)上的非常小的突起(10-2),所以通过用作芯的突起(10-2)促进了冷凝。 这样即使在低露点也有利于冷凝和改善反应。 此外,缩合产物的大小相对于待测气体的流速的变化不容易变化,这使得凝结的平衡不太可能破裂,从而提高测量精度。
