    • A method and a ballast for starting a discharge lamp capable of making a rapid start while restraining the overshoot of the light output. The ballast can separately give the initial start time period of applying a maximum power rating to the lamp and the subsequent curve along which the power decreases to a normal power rating of the lamp. A power is varied along a particular run-up curve so as to apply the maximum power rating and subsequently apply the power decreasing to the normal power rating. The run-up curve is derived from a reference curve having a power level decreasing with time. The reference curve has a maximum value above the maximum power rating, and has an inflection point near the maximum power rating to define first and second reference curves above and below the inflection point, respectively. The first reference curve has a first average slope for a first time period from a point of the maximum value to the inflection point. The second reference curve has a second average slope for a second time period which starts from the inflection point and has the same length as the first time period. The second average slope is greater than the first average slope. The run-up curve is a continuous composite curve of the maximum power rating defined by a portion thereof below the reference curve and the remainder of the reference curve defined between the maximum power rating and the normal power rating.
    • 一种用于启动放电灯的方法和镇流器,其能够在抑制光输出的过冲的同时快速启动。 镇流器可以分别给灯施加最大额定功率的初始启动时间段和随后的功率降低到灯的正常额定功率的曲线。 功率沿特定的起动曲线变化,以应用最大功率额定值,并随后将功率降低应用于正常额定功率。 起动曲线从功率电平随时间减小的参考曲线导出。 参考曲线具有高于最大额定功率的最大值,并且具有接近最大额定功率的拐点,以分别在拐点上方和下方限定第一和第二参考曲线。 第一参考曲线具有从最大值到拐点的第一时间段的第一平均斜率。 第二参考曲线具有从拐点开始并且具有与第一时间段相同的长度的第二时间段的第二平均斜率。 第二平均斜率大于第一平均斜率。 起动曲线是由其低于参考曲线的部分定义的最大额定功率的额定值和在最大额定功率与正常额定功率之间定义的参考曲线的剩余部分的连续复合曲线。

    • A ballast for a discharge lamp capable of reliably and successfully detecting the end of the lamp life and ceasing the ballast immediately upon detection of the lamp's life end. The ballast includes a power supply providing from a power source a variable power to the lamp, and a power controller controlling the power supply to apply a high voltage for igniting the lamp and subsequently apply a predetermined power for operating the lamp. A lamp life detector is included in the ballast to detect whether or not the lamp comes to a lamp's life end. Also included in the ballast is a supervisor which issues, upon detection of the lamp's life end, a disable signal prohibiting the power supply from lighting the discharge lamp. The power controller provides a detection period of a limited short time period starting from energization of the ballast such that the lamp life detector can detect the lamp's life end and issue a lamp's life end signal only when there is an extinction of lamp within the detection period, and that the supervisor issues, after the elapse of the detection period, an enable signal permitting the power supply to ignite the discharge lamp if the lamp is extinguished after the elapse of the detection period.
