摘要： Systems and methods are disclosed that facilitate sensing a pulse in a ballast circuit for a lamp when the lamp is in an end-of-life (EOL) stage or when the lamp is experiencing an arcing conduction condition, such as may occur when a contact between the lamp and its holder is compromised. Upon sensing the pulse, a micro controller may distinguish between EOL and arcing conditions based on detected pulse width(s), and may initiate an appropriate response. For instance, if the pulse is due to an arcing event, the micro controller may interrupt lamp operation for a brief period before restarting the lamp to mitigate the arcing condition. If the pulse is caused by an EOL condition, the micro controller may place the lamp in a preheat or restarting mode to hasten lamp failure. In either case, responses to the sensed pulse mitigate the occurrence of dangerously high lamp temperatures that may damage lamp sockets.
摘要翻译：公开了系统和方法，当灯处于寿命终止阶段（EOL）阶段时或当灯经历电弧导通条件时，诸如在接触时可能发生的情况，便于感测用于灯的镇流器电路中的脉冲在灯与其支架之间受到损害。一旦检测到脉冲，微控制器可以基于检测到的脉冲宽度来区分EOL和电弧条件，并且可以启动适当的响应。例如，如果脉冲是由于电弧事件引起的，微控制器可能在重新启动灯泡之前短时间内中断灯的工作，以减轻电弧状态。如果脉冲是由EOL状态引起的，则微控制器可能会将灯置于预热或重新启动模式，以加快灯泡故障。在任一种情况下，对感测脉冲的响应可以减轻可能损坏灯泡插座的危险的高灯温度的发生。

摘要： An electronic ballast circuit for a lamp is described, wherein the ballast comprises a power factor correction circuit coupled to an inverter circuit. The inverter circuit is further coupled to a trigger circuit, which is in turn operatively connected to a hot or neutral line of a power supply by a control line. Upon closing a switch in the control line, the trigger circuit operates to place a capacitor in parallel with a base drive winding of a transistor in the inverter circuit, causing the inverter circuit to shut down. When the switch is opened, the trigger circuit shuts off and the inverter starts up and returns to an oscillating state.

摘要： The present application claims a compact low cost topology solution of a ballast for a discharge lamp that can provide both high power factor and low total harmonic distortion with fewer components than prior art. The topology provides the feature of a low crest factor and quick start that increase both the lamp life and the number of starts for the product. By using Bipolar Junction Transistor instead of Field Effect Transistor as the main switches and also a lower value electrolytic, the cost and size are considerably reduced.
