There are no restrictions in this creation.

Please refer to FIG. 4. FIG. 4 is a schematic diagram of the dimming module of the present embodiment.

In this embodiment, the dimming module 12 includes a dimming signal detecting unit 121, a processing unit 122, and a timing unit 123.

The dimming signal detecting unit 121 and the timing unit 123 are electrically connected to the processing unit 122, respectively. The dimming signal detecting unit 121 is electrically connected to a signal input terminal 12-IN of the dimming module 12. The signal input terminal 12-IN of the dimming module 12 is electrically connected to the input module 11 of the LED illumination device 1 and receives the power signal PS transmitted by the input module 11.

The dimming signal detecting unit 121 is configured to detect whether at least one dimming unit signal DIMUS is included in the power signal PS. In the embodiment, the dimming signal detecting unit 121 is a waveform of detecting a plurality of unit signals US of the power signal PS. To determine whether the power signal PS includes at least one dimming unit signal DIMUS. For example, the power signal PS includes a total of N unit signals US in the first time interval T1, wherein the first unit signal US of the N unit signals US is a dimming unit signal. DIMUS. The dimming signal detecting unit 121 calculates the time of the first time interval T1, that is, the time of the N unit signals US according to a clock signal provided by the timing unit, and detects whether the waveform of each unit signal US is consistent. In the embodiment, since the power signal PS is from the mains circuit network, the normal waveform of the unit signal US will be a sine wave, but the dimming unit signal DIMUS is the phase-cut unit signal US, so the waveform will be only a part. The sine wave, as shown in Fig. 3B, the waveform of the dimming unit signal DIMUS is cut off at 0~π/2 and π~3π/2, and the amplitude variation is significantly different from the sine wave, therefore, the dimming signal The detecting unit 121 can determine whether the power signal PS includes at least one dimming unit signal DIMUS according to the waveform of the plurality of unit signals US.

Taking a voltage of 110V and a frequency of 60Hz as an example, a unit signal US is 1/60 second, and the first time interval T1 can be selected as the sum time of 6 unit signals US, that is, 1/10 second, that is, 0.1 second. Wherein, the dimming unit signal DIMUS is at the position of the first unit signal US of the first time interval T1. In other embodiments, the dimming unit signal DIMUS can be set at any one of the unit signals US of the first time interval T1, which can be adjusted and designed according to actual needs, and is not limited in the present creation.

In the present embodiment, when the dimming signal detecting unit 121 detects the dimming unit signal DIMUS, the voltage information and the phase cutting information according to the detected dimming unit signal DIMUS are supplied to the processing unit 122. The processing unit 122 generates a dimming notification signal DIMNS according to the voltage information and phase cutting information of the dimming unit DIMUS.

In this embodiment, the dimming module 12 further includes a timing unit 123 for detecting the frequency of the power signal PS, so that the dimming module 12 performs the adjustment of the first time interval T1.

When the light-emitting diode lighting device 1 is switched from the 100V/50Hz power environment to the 100V/60Hz power environment, the adjustment of the first time interval T1 can be adjusted according to the reception of the plurality of unit signals US. For example, at 100V/50Hz In the power environment, the first time interval T1 is 0.1 second, and the fifth unit signal US is included in the first time interval T1, and the dimming unit signal DIMUS is set at the position of the first unit signal US of the first time interval T1. That is, the unit signal US for every four sine waves is matched with one dimming unit signal DIMUS. However, in the 100V/60Hz power environment, if the first time interval T1 of the US unit time of the 5 unit signals is maintained, the first time interval T1 is 1/12 second, which is approximately equal to 0.083 seconds, although with 100V/50Hz. The first time interval T1 (0.1 sec) in the power environment is similar, but the detection error is prone to occur. If the original first time interval T1 (0.1 sec) is detected, the dimming unit signal DIMUS is detected, and the detection in the first time interval T1 is performed. In time, one more unit signal US will be used. Then, the dimming unit signal DIMUS of the next first time interval T1 is detected, and a situation in which the dimming unit signal DIMUS is set to be displaced in the first time interval T1 occurs. Therefore, the dimming module 12 can detect the frequency of the power signal PS by the dimming signal detecting unit 121 and the timing unit 123, and adjust the first time interval T1, that is, the first time interval T1 can be from the 100V/50Hz power environment. The 0.1 second is adjusted to 0.083 seconds of the 100V/60Hz power environment to maintain the first time interval T1, and a total of 5 unit signals US can be detected, wherein if there is a dimming unit signal DIMUS, it is set at 5 The first position of the unit signal US.

In other embodiments, the dimming unit signal DIMUS is not easily detected or misjudged due to a lot of noise in the power environment. Therefore, the dimming unit signal DIMUS can be sent once every once time. Continuously transmitting 2-3 times, or sending it once every several unit signals US, and continuously transmitting 2-3 times, so that the dimming module 12 of the light-emitting diode lighting device 1 can surely detect the dimming unit. The signal DIMUS is used to enable the light-emitting diode illumination device 1 to adjust the brightness correspondingly.

For example, when the dimming unit signal DIMUS is sent twice, if the dimming module 12 includes the timing unit 123, when the dimming signal detecting unit 121 detects a dimming unit signal DIMUS, the processing unit 121 can pass the timing unit 123. Timing work The dimming unit signal DIMUS detected by the dimming signal detecting unit 121 in the two first time intervals T1 is analyzed, and a dimming notification signal DIMNS is provided to the processing mode in combination with the dimming information parsed twice before and after. Group 13, to reduce the impact of power environment noise on detecting the dimming unit signal DIMUS.

Therefore, the dimming module 12 can further include a counting unit 124 for calculating the number of unit signals US. When the dimming signal detecting unit 121 of the dimming module 12 detects the dimming unit signal DIMUS, the processing unit 122 parses the detected dimming unit signal DIMUS to obtain dimming information, and the counting unit 124 is from 1 Start counting, when counting to a predetermined number M, the dimming signal detecting unit 121 detects another dimming unit signal DIMUS, and the processing unit 122 performs dimming information analysis on another dimming unit signal DIMUS, and the processing unit 122 combines The dimming information is analyzed twice before and after, and a dimming notification signal DIMNS is provided to the processing module 13 to reduce the influence of the power environment noise on detecting the dimming unit signal DIMUS.

In this embodiment, the timing unit 123 and the counting unit 124 are optional functional units, which can be designed and adjusted according to actual needs, and are not limited in the present creation.

In this embodiment, after the processing module 13 provides the load dimming signal LDIMS to the driving module 14, the brightness of the LED module 15 is locked after a period of time, that is, the dimming is received next time. Before the unit signal, the brightness of the light-emitting diode module 15 of the light-emitting diode lighting device 1 does not change any more.

In addition, the power signal PS in the present embodiment has a dimming unit signal DIMUS only in the first time interval T1 during the dimming period, and the other unit signals US are unit signals US in the shape of a sine wave, which can ensure the light emitting diode. When the illumination device 1 has a low luminance, since there is a sufficient voltage supply, there is no possibility of flickering. During the non-dimming period, each unit signal US of the power signal PS is a sine wave.

[Embodiment of the Creative Dimming Module]

Referring to FIG. 4, the dimming module 12 of the present embodiment is disposed in a light-emitting diode lighting device 1 for adjusting the brightness of the light-emitting diode lighting device 1.

The power signal input terminal 12-IN is for receiving a power signal PS. In this embodiment, the power signal is an AC power signal, that is, the power signal PS includes a plurality of unit signals US.

In this embodiment, the frequency of the power signal is 50 Hz or 60 Hz. That is, between 50Hz and 60Hz. If the frequency error of 5% is considered, the frequency of the power signal PS is between 47 Hz and 63 Hz. That is, taking 60 Hz as an example, the power signal PS includes 60 unit signals US per second. In this embodiment, the unit signal US can be a sine wave or other waveforms, which can be adjusted according to actual needs, and no other restrictions are imposed in the present creation.

The dimming signal detecting unit 121 is electrically connected to the signal input terminal 12-IN for detecting whether the power signal PS includes at least one dimming unit signal DIMUS, and if the dimming signal detecting unit 121 detects that the power signal PS includes at least one dimming The unit signal DIMUS outputs a dimming notification signal DIMNS.

As shown in FIG. 3A and FIG. 3B, for example, the power signal PS includes a total of N unit signals US in the first time interval T1, wherein the first unit signal US at the N unit signals US is a dimming unit signal. DIMUS. The dimming signal detecting unit 121 calculates the time of the first time interval T1, that is, the time of the N unit signals US according to a clock signal provided by the timing unit, and detects whether the waveform of each unit signal US is consistent. In the embodiment, since the power signal PS is from the mains circuit network, the normal waveform of the unit signal US will be a sine wave, but the dimming unit signal DIMUS is the phase-cut unit signal US, so the waveform will be only a part. The sine wave, as shown in Fig. 3B, the waveform of the dimming unit signal DIMUS is cut off at 0~π/2 and π~3π/2, and the amplitude variation is significantly different from the sine wave, therefore, the dimming signal The detecting unit 121 can be based on a plurality of units The waveform of the signal US determines whether the power signal PS includes at least one dimming unit signal DIMUS.

In this embodiment, N is equal to 5. In other embodiments, N can be adjusted according to actual needs, and is not limited in the present creation.

That is, when the signal input terminal 12-IN of the dimming module 12 receives the power signal PS having the dimming unit signal DIMUS, the processing unit 122 of the dimming module 12 passes the signal output terminal 12 according to the dimming unit signal DIMUS. -OUT provides a dimming notification signal DIMNS.

When the power signal PS received by the signal input terminal 12-IN of the dimming module 12 does not include the dimming unit signal DIMUS, the processing unit 122 of the dimming module 12 does not provide any signal through the signal output terminal 12-OUT.

In the present embodiment, when the dimming signal detecting unit 121 detects the dimming unit signal DIMUS, the voltage information and the phase cutting information according to the detected dimming unit signal DIMUS are supplied to the processing unit 122. The processing unit 122 generates a dimming notification signal DIMNS according to the voltage information and phase cutting information of the dimming unit DIMUS.

In this embodiment, the dimming module 12 further includes a timing unit 123 for detecting the frequency of the power signal PS, so that the dimming module 12 performs the adjustment of the first time interval T1.

When the light-emitting diode lighting device 1 is switched from the 100V/50Hz power environment to the 100V/60Hz power environment, the adjustment of the first time interval T1 can be adjusted according to the reception of the plurality of unit signals US. For example, in a 100V/50Hz power environment, the first time interval T1 is 0.1 seconds, the first time interval T1 includes 5 unit signals US, and the dimming unit signal DIMUS is set at the first time interval T1. The position of a unit signal US, that is, the unit signal US for every four sine waves is matched with one dimming unit signal DIMUS. However, in the power environment of 100V/60Hz, if the first time interval T1 of the total unit time of the five unit signals is maintained, the first time interval T1 is 1/12 second, which is approximately equal to 0.083 seconds, although It is similar to the first time interval T1 (0.1 sec) in the 100V/50Hz power environment, but it is prone to detection error. If the original first time interval T1 (0.1 sec) is detected, the dimming unit signal DIMUS is detected, at the first time. In the detection time of the interval T1, one unit signal US is added. Then, the dimming unit signal DIMUS of the next first time interval T1 is detected, and a situation in which the dimming unit signal DIMUS is set to be displaced in the first time interval T1 occurs. Therefore, the dimming module 12 can detect the frequency of the power signal PS by the dimming signal detecting unit 121 and the timing unit 123, and adjust the first time interval T1, that is, the first time interval T1 can be from the 100V/50Hz power environment. The 0.1 second is adjusted to 0.083 seconds of the 100V/60Hz power environment to maintain the first time interval T1, and a total of 5 unit signals US can be detected, wherein if there is a dimming unit signal DIMUS, it is set at 5 The first position of the unit signal US.

In other embodiments, the dimming unit signal DIMUS is not easily detected or misjudged due to a lot of noise in the power environment. Therefore, the dimming unit signal DIMUS can be sent once every once time. Continuously transmitting 2-3 times, or sending it once every several unit signals US, and continuously transmitting 2-3 times, so that the dimming module 12 of the light-emitting diode lighting device 1 can surely detect the dimming unit. The signal DIMUS is used to enable the light-emitting diode illumination device 1 to adjust the brightness correspondingly.

For example, when the dimming unit signal DIMUS is sent twice, if the dimming module 12 includes the timing unit 123, when the dimming signal detecting unit 121 detects a dimming unit signal DIMUS, the processing unit 121 can pass the timing unit 123. The timing function analyzes the dimming unit signal DIMUS detected by the dimming signal detecting unit 121 in the two first time intervals T1, and combines the dimming information parsed twice before and after, and provides a dimming notification signal DIMNS for processing. The module 13 is configured to reduce the influence of power environment noise on detecting the dimming unit signal DIMUS.

Therefore, the dimming module 12 can further include a counting unit 124 for calculating the number of unit signals US. When the dimming signal detecting unit 121 of the dimming module 12 detects When the unit signal DIMUS is dimmed, the processing unit 122 parses the detected dimming unit signal DIMUS to obtain dimming information, and the counting unit 124 starts counting from 1 and counts to a predetermined number M, and the dimming signal is detected. The unit 121 detects another dimming unit signal DIMUS, and the processing unit 122 performs dimming information analysis on the other dimming unit signal DIMUS, and the processing unit 122 combines the dimming information parsed twice before and after to provide a dimming notification signal. The DIMNS is applied to the processing module 13 to reduce the influence of power environment noise on detecting the dimming unit signal DIMUS.

In this embodiment, M is equal to 5. In other embodiments, M can be adjusted according to actual needs, and is not limited in the present creation.

In this embodiment, after the dimming signal detecting unit 121 no longer detects the dimming unit signal DIMUS, the processing unit 122 of the dimming module 12 does not output the dimming notification signal DIMNS.

In this embodiment, the timing unit 123 and the counting unit 124 are optional functional units, which can be designed and adjusted according to actual needs, and are not limited in the present creation.
