Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0030] Please refer to Figure 1This is a block diagram of a first specific embodiment of the two-wire carrier-controlled LED system 10 of the present invention. The two-wire carrier-controlled LED system 10 of the present invention is applied to an AC power supply 108. The two-wire carrier-controlled LED system 10 includes a microcontroller circuit 102, an AC power detector 104, and a plurality of LED lamps 106, all of which are electrically connected to each other. The LED lamps 106 receive the AC power supply 108 as their operating power source. The LED lamps 106 are configured to receive a plurality of light emission control signals 110 and emit light according to these light emission control signals 110 (i.e., the LED lamps 106 are driven by the light emission control signals 110 to change their light emission, as will be described in detail later). The AC power supply 108 may be a 120-volt AC power supply, but is not limited thereto; the LED lamps 106 are connected in parallel with each other.

[0031] Furthermore, please refer to Figure 2 This is a block diagram of a second specific embodiment of the two-line carrier point-controlled light-emitting diode system 10 of the present invention. Figure 2 The components shown are Figure 1 For the sake of simplicity, identical components will not be described again here. The two-wire carrier-controlled LED system 10 also includes an AC power supply 170, which is electrically connected to the microcontroller circuit 102, the AC power detector 104, and the LED lamps 106; the AC power supply 170 generates and outputs the AC power 108. Each of the LED lamps 106 includes a unique address code 172, and the light emission control signal 110 includes address data 166 and light emission data 168. When each of the LED lamps 106 receives the light emission control signals 110, each of the LED lamps 106 is configured to compare the address data 166 and the local address code 172; if the address data 166 is equal to the local address code 172, then the LED lamp 106 is configured to emit light according to the light emission data 168; if the address data 166 is not equal to the local address code 172, then the LED lamp 106 is configured to ignore the light emission data 168.

[0032] Please refer to Figure 3 This is a circuit diagram of a specific embodiment of the microcontroller circuit 102 and the AC power detector 104 of the two-wire carrier point-controlled light-emitting diode system 10 of the present invention in a second specific embodiment. Figure 3 The components shown are Figure 2For the sake of simplicity, identical components will not be described again here. The two-wire carrier-controlled LED system 10 also includes a first capacitor 128, a rectifier diode 130, a clamping diode 132, and a second capacitor 134; the microcontroller circuit 102 includes a first switch 114, a microcontroller module 176, and a microcontroller operating voltage source 122; the microcontroller module 176 includes a microcontroller 112, a first clamping diode 116, a second clamping diode 118, and a resistor 120; the AC power detector 104 includes a detection resistor 124 and a detection capacitor 126; all these components are electrically connected to each other. Figure 3 The microcontroller 112 may be of the model number, but the present invention is not limited to DJ6244 or DJ6246, or any microcontroller that can achieve the same function.

[0033] When it is necessary to control the LED lamps 106 to emit light, the microcontroller module 176 detects the voltage state of the AC power supply 108 through the AC power detector 104; the microcontroller module 176 continuously switches the conduction state of the first switch 114 along the voltage change of the AC power supply 108 within one half-wave cycle to change the voltage transmitted to the LED lamps 106 to generate the light emission control signals 110.

[0034] The microcontroller module 176 detects the voltage state of the AC power supply 108 through the detection resistor 124 and the detection capacitor 126. The first clamping diode 116 and the second clamping diode 118 clamp the AC power supply 108 to obtain a first square wave signal and transmit the first square wave signal to the microcontroller 112 so that the microcontroller 112 can determine and detect the voltage state of the AC power supply 108.

[0035] The signal strength of the light-emitting control signals 110 is sufficient for the LED lamps 106 to recognize them and is greater than the reset voltage of the LED lamps 106. The significance of the sufficient signal strength of the light-emitting control signals 110 is twofold: first, the potential difference (e.g., 2-3 volts) is large enough for the LED lamps 106 to recognize the light-emitting control signals 110; if the potential difference is too small, the LED lamps 106 will not be able to recognize the light-emitting control signals 110; second, the minimum voltage value of the signal strength of the light-emitting control signals 110 is greater than the reset voltage of the LED lamps 106, thus preventing the LED lamps 106 from resetting.

[0036] Please refer to Figure 6 It is used for Figure 3 A waveform diagram of a specific embodiment of the first switch 114 that generates the light-emitting control signals 110; Figure 6The preset value a1 shown (i.e., the signal strength of the aforementioned light-emitting control signals 110 is strong enough) can be an operating voltage value of the LED lamps 106, and the light-emitting control signals 110 include a plurality of pulse signals 174. If the signal length of the light-emitting control signals 110 is greater than the half-wave period, the microcontroller module 176 switches the first switch 114 in the next half-wave period with the same AC power supply voltage change to complete the generation of the light-emitting control signals 110; here, the signal length is defined as the signal length of all the light-emitting control signals 110 (i.e., all the pulse signals 174). Furthermore, the present invention can also be applied to AC power supplies after rectification, thus eliminating the need to wait for a half-wave period interval.

[0037] Please refer to Figure 4 This is a circuit diagram of another specific embodiment of the microcontroller circuit 102 and the AC power detector 104 of the two-wire carrier point-controlled light-emitting diode system 10 of the present invention.

The two-wire carrier-controlled LED system 10 also includes a first capacitor 128, a rectifier diode 130, a clamping diode 132, a second capacitor 134, and a voltage divider resistor 138; the microcontroller circuit 102 also includes a second switch 136; all these components are electrically connected to each other. Figure 4 The microcontroller 112 may be, for example, but is not limited to, the DJ6374, or any microcontroller that can achieve the same function. The clamping diode 132 is used to clamp the AC power supply 108 to supply power to the microcontroller 112.

[0038] The microcontroller module 176 continuously switches the on state of the first switch 114 or the on state of the second switch 136 within a full-wave cycle along the voltage change of the AC power supply 108 to change the voltage transmitted to the LED lamps 106 and generate the light-emitting control signals 110. The first switch 114 is connected in series with the second switch 136; when the AC power supply 108 is in the positive half-cycle, the microcontroller module 176 switches the first switch 114 to generate the light-emitting control signals 110; when the AC power supply 108 is in the negative half-cycle, the microcontroller module 176 switches the second switch 136 to generate the light-emitting control signals 110.

[0039] Please refer to Figure 7 It is used for Figure 4The waveform diagram shows a specific embodiment of the first switch 114 and the second switch 116 used to generate the light emission control signals 110. If the signal length of the light emission control signals 110 is greater than the half-wave period, the microcontroller module 176 switches the first switch 114 or the second switch 136 in the next consecutive half-wave period to complete the generation of the light emission control signals 110; that is, switching between positive and negative half-cycles (different voltage changes); the microcontroller module 176 first switches the first switch 114 and then switches the second switch 136 to complete the generation of the light emission control signals 110; when one of the first switch 114 and the second switch 136 is switched, the other of the first switch 114 and the second switch 136 stops switching.

The detection resistor 124 can be, for example, but not limited to, a 1M ohm resistor or a 2M ohm resistor. The AC power detector 104 may not necessarily include the detection capacitor 126. The first capacitor 128 can be, for example, but not limited to, a 10uF capacitor. The clamping diode 132 can be, for example, but not limited to, a 5.1-volt clamping diode.
