摘要： A method for revealing a light signal error, in particular for railway safety systems, and a device for carrying out the method includes an electronic signal generator, which can be disconnected in a reversible manner in the event of an error, and a control part which is designed for incandescent lamps for controlling and monitoring the signal generator. In order to be able to evaluate the operation of said type of control part with an incandescent lamp interface also when the signal is flashing, it is provided that when the signal generator is activated in the flashing mode, in which no signal voltage is supplied during the flashing intervals, a timer which is connected to a voltage source measures the duration of the pauses between the flashes, and in the event of an error, maintains the disconnection for at least one flashing cycle and signals to the control part.

摘要： A string set of series-connected incandescent bulbs in which the bulbs are individually provided with a voltage responsive shunt which is inoperative during normal operation of the string set when connected to a source of operating potential and which becomes operative only in response to an increase in the voltage thereacross which exceeds its rating, and in which the remaining bulbs of the circuit continue to receive rated current therethrough and rated voltage thereacross and further continue to be illuminated even though other bulbs in the string are either inoperative or are missing from their respective sockets. The string includes a split bridge AC to DC converter which provides pulsating DC current to the shunted, series-connected incandescent bulbs.

摘要： A power control method and system of a lamp are provided. The method includes supplying, by a controller, the lamp with electric power and selecting an illumination characteristic data of the lamp changed from a point when the electric power starts to be supplied to the lamp. The duty of voltage supplied to the lamp is variably adjusted, by the controller, based on the illumination characteristic data. In addition, the controller counts a first elapsed time that elapses from a first point when the electric power supplied to the lamp is turned on, and variably adjusts the duty of the voltage supplied to the lamp based on the counted first elapsed time.

摘要： The present invention relates to a dimming angle sensing circuit and a driving method thereof.A dimming angle sensing circuit according to an exemplary embodiment of the present invention uses a zener diode. The dimming angle sensing circuit generates a comparison voltage according to a comparison result of a line voltage and a zener voltage. The line voltage is generated from rectification of an AC input passed through a dimmer. The dimming angle sensing circuit generates a sense voltage corresponding to a dimming angle of the dimmer by low-pass filtering the comparison voltage.

摘要： According to one embodiment of the invention, a method comprises receiving a time-varying power waveform. The power waveform may be periodic and/or phase-controlled. Compressed within a power range associated with the time-varying power waveform, a pulse width modulated (PWM) signal is produced, which is supplied to a light source in order to produce a lighting effect emulating lighting from a candle flame.
