    • Technology presented in the following utility patent yields a significant innovation within the field of electrical lighting. An alternative configuration of the filter inductor, which serves as part of a passive power factor correction circuit, increases the overall efficiency of fluorescent ballast. The core of the inductor is essentially comprised of a vertically positioned, laminated silicon steel stack within the electronic ballast housing. The vertical orientation allows for a significant reduction in the height and width of the ballast housing, thus creating more effective use of space. Furthermore, each individual laminated silicon steel plate's outside corner angles assume a crescent moon shape. This unique structure serves to provide additional space for the ballast's input lead wires by forming total three (3) of long narrow channels. In order to balance any offset in magnetic flux density caused by the crescent moon shape, the two alternate interior angles of the sheet are arc-shaped.
    • 在以下实用专利中提出的技术在电气照明领域产生了重大创新。 作为无源功率因数校正电路的一部分的滤波电感器的替代配置提高了荧光镇流器的总体效率。 电感器的核心主要由电子镇流器壳体内的垂直定位的叠层硅钢叠层组成。 垂直方向允许压载壳体的高度和宽度显着降低,从而产生更有效地利用空间。 此外,每个单独的层叠硅钢板的外角角呈月牙形。 这种独特的结构通过形成总共三(3)个长窄通道,为镇流器的输入引线提供额外的空间。 为了平衡由新月形形成的磁通密度的任何偏移,片材的两个交替的内角是弧形的。

    • An electronic ballast for a fluorescent lamp includes a delay triggered circuit which, upon expiration of a predetermined period during which the lamp filaments, constituting opposite electrodes of the lamp, are preheated, applies high frequency operating voltage across the opposite electrodes of the lamp beginning with a transition from a condition of no voltage to a condition of full rated voltage which occurs within one cycle of the high frequency voltage. The sharp transition from zero "glow current" to full "arc current" at the end of the preheating period has been found to increase the life of lamps in the number of on-off starts, particularly with respect to lamps of poor quality. The rapid transition is possible because the ballast uses the same inverter and transformer for supplying preheating and operating voltages. The operating voltage is applied between the opposite electrodes of the lamp via an electronic bi-directional switch, controlled by a preheating delay RC timing circuit.
    • 用于荧光灯的电子镇流器包括延迟触发电路,在预定时间期间,构成灯的相对电极的灯丝被预热,在从灯开始的相对电极上施加高频工作电压, 从无电压状态到在高频电压的一个周期内发生的全额定电压的条件的转变。 已经发现在预热期结束时从零“辉光电流”到完全“电弧电流”的急剧转变,以增加开关次数开始时灯的寿命,特别是对质量差的灯而言。 快速转换是可能的,因为镇流器使用相同的逆变器和变压器来提供预热和工作电压。 工作电压通过电子双向开关施加在灯的相对电极之间,由预热延迟RC定时电路控制。
