    • A captured offset linear guide system for a lighting control device includes a faceplate having an elongated slot, a knob, an offset member, and a linear potentiometer. The offset member allows the linear potentiometer to be offset from the elongated slot of the faceplate to prevent dirt and dust from collecting on the potentiometer. Also, utilization of the offset member eliminates safety concerns of a tool being inserted into the internal structure of the lighting control device where it might come into contact with energized electrical components. The faceplate includes two guide rails, which hold the offset member close to the faceplate and allow for easy assembly of the faceplate to the lighting control device. Further, the faceplate includes an alignment rail, which keeps the offset member straight when moving within the slot.

    • A microcontroller or state machine controls a light ballast utilizing a timer structure. The microcontroller can program the timer structure to generate pulses where the "average" frequency of a series of pulses can be varied with higher resolution than the frequency of a single pulse. This variation can occur without further microcontroller/state machine intervention. The pulses are used to control the on and/or off time of the light. The timer can be configured to modulate the outputs fast enough to ensure that the light does not appear to flicker to the human eye by limiting the number of pulses in a frame and by increasing the number of times the frequency shift occurs compared to the obvious implementation. The present invention relies on the fact that the human eye is not capable of detecting small frequency changes in high frequency signals and therefore uses pulses of two or more frequencies where the frequencies are close together. The average frequency can then be varied at much higher resolution than any single frequency.
    • 微控制器或状态机利用定时器结构控制光镇流器。 微控制器可编程定时器结构以产生脉冲,其中一系列脉冲的“平均”频率可以以比单个脉冲的频率更高的分辨率改变。 这种变化可以在没有进一步的微控制器/状态机干预的情况下发生。 脉冲用于控制光的接通和/或关闭时间。 定时器可以被配置为足够快地调制输出,以便通过限制帧中的脉冲数和通过增加发生频移的次数,明显地实现了对于人眼的闪烁。 。 本发明依赖于人眼不能检测高频信号中的小频率变化,因此使用频率接近在一起的两个或更多个频率的脉冲。 然后可以以比任何单个频率高得多的分辨率来改变平均频率。

    • An input line filter (28) separates an ac sinusoidal power source (22) from a power switching stage (26) having a series switching section (44) and a clamp switching section (46). Both the series switching section (44) and the clamp switching section (46) include complementary pairs (68-70 and 86-88) of high power and high speed MOSFETs. The series switching section (44) is connected in series between the input line filter (28) and the inductor (42) of an output load filter (38) between the power switching stage (26) and a load (24). The clamp switching section (46) is connected to shunt the inductor (42) and load (24). Synchronous operation is achieved by alternately operating the series (44) and clamp (46) switching sections to conductive conditions at a high pulse width modulation frequency. The duty cycle is selected to provide a sinusoidal output waveform with a desired amplitude. A microprocessor based programmable controller (56) provides control signals (102, 106) for alternate conduction of the series (44) and clamp (46) switching sections. A dead time interval (110, 112) stored in memory in the controller (56) separates the control signals (102, 106) for reliable and efficient operation. The dead time interval (110, 112) may be constant, or may be varied in accordance with load power variations.
