  • Dimming apparatus transmitting control signals with AC power line
    Patent number: 8441205
    Abstract: A dimming apparatus transmitting control signals with AC power line (10) is applied to an alternating current power source (20), a light emitting diode driving power unit (40), and a light emitting diode unit (30). The dimming apparatus transmitting control signals with AC power line (10) includes an input voltage detection unit (102), a one-shot signal unit (104), an AND gate unit (106), a pulse width modulation dimming signal unit (108), an inductor unit (110), a first switch unit (114), a dimming signal recovery unit (124), and a second switch unit (122). The input voltage detection unit (102) is electrically connected to the alternating current power source (20), the inductor unit (110), and the one-shot signal unit (104). The AND gate unit (106) is electrically connected to the one-shot signal unit (104), the pulse width modulation dimming signal unit (108), and the first switch unit (114).
