Abstract:
A remote control unit for an incandescent lamp comprising:a remote controller for transmitting a remote control signal for controlling the lamp through the air; anda lamp controller comprising:a rectifier for receiving an external AC power and rectifying the same into DC power of a predetermined level;a sensor driven by the DC power supplied from the rectifier, for receiving the remote control signal;a signal processor driven by the DC power supplied from the rectifier, for receiving and analyzing the remote control signal from the sensor and generating a lamp control signal indicative of the current state of the lamp;a synchronizer for receiving the AC power and generating a synchronization signal indicative of a starting point of the waveform of the AC power;a pulse generator driven by the DC power supplied from the rectifier, for generating pulse streams for limiting the current applied to the lamp in accordance with the lamp control signal supplied from the signal processor on the basis of the synchronization signal; anda lamp connector connected to the AC power through the lamp, for controlling the current flowing through the lamp for every half cycle of the waveform of the AC power after the timing at which pulses are generated by the pulse generator.
