    • PURPOSE: An electronic ballast and a lighting fixture are provided to stabilize an output of a load circuit while the temperature of a current transformer is changed. CONSTITUTION: A driving circuit(5) is arranged between a switching circuit(3) and a load circuit(4). The driving circuit is provided with feedback wires(CT1b,CT1c) magnetically connected to a detecting wire of a current transformer(CT1). The driving circuit is configured to control a switching frequency of first and second switching elements(Q1,Q2) according to the detected current of the detecting coil. A magnetic energy control device(6) is configured to control the magnetic energy of the current transformer. A current detecting device(7) detects the average current either the output current of the direct current power supply or the current of the switching circuit. A current control device(8) is configured to control the magnetic energy control device and to fix the average current to a designated value.

    • PURPOSE: A power supply unit and a lighting apparatus are provided to prevent arc to be continued by preparing a period which relatively reduces an output current at every 1 cycle. CONSTITUTION: A lighting apparatus comprises a tubular type LED lamp(16) having an apparatus body and a semiconductor light emitting device(25) and an exclusive electricity source(17) which turns on the semiconductor light emitting device. The exclusive electricity source turns one the semiconductor light emitting device by outputting the current of a trapezoid wave shape corresponding to more than 54% of one cycle of a peak period. A LED lamp system has a main body unit which is installed to ceiling and the reflector of an inverted triangle which is attached to the main body unit. The LED lamp system comprises a socket(14) as a pair of light source attachment means.
    • 目的:提供电源单元和照明装置,以通过准备在每1个周期相对减小输出电流的周期来防止电弧继续。 构成:照明装置包括具有装置主体和半导体发光装置(25)的管状型LED灯(16),以及导通半导体发光装置的专用电源(17)。 专用电源通过输出对应于峰值周期的一个周期的54%以上的梯形波形的电流来使半导体发光器件成为一个。 LED灯系统具有安装在天花板上的主体单元和附接到主体单元的倒三角形的反射器。 LED灯系统包括作为一对光源附接装置的插座(14)。
