According to the embodiment, the button signal of the switching module 101 may comprise a number of triggering signals St continuously triggered on the switching module 101. The signal processing module 102 is coupled with the switching module 101. The signal processing module 102 is arranged to count the number of triggering signals St continuously triggered on the switching module 101, and to generate the adjusting signal Sa according to the counting number. Therefore, the adjusting signal Sa comprises the messages triggered on the switching module 10. The messages of the adjusting signal Sa are arranged to be one-to-one correspond to the different numbers of triggering signals St continuously triggered on the switching module 101. Furthermore, the signal processing module 102 is capable of determining if the switching module 101 is triggered by user. When the switching module 101 is triggered, the state of the switching module 101 is changed, and the lighting device controlling circuit 10 is capable of controlling the lighting device 30 accordingly. For example, every time the switching module 101 is triggered, the state of the switching module 101 is either changed to the disconnecting state from the connecting state, or changed to connecting state from the disconnecting state. When the switching module 101 is triggered continuously, the triggering signals St of the switching module 101 may include the message of function selected by the user such that the lighting device 30 may generate the corresponding color and brightness. When the signal processing module 102 obtains the number of triggering signals St continuously triggered on the switching module 101, the signal processing module 102 generates the corresponding adjusting signal Sa. The adjusting signal Sa is capable of adjust the illuminating state of the lighting device 30. Accordingly, the user may control the lighting device 30 to generate the required color and brightness according to the button message. Therefore, the lighting device controlling circuit 10 may have better user experience.
The power inputting terminal Ni of the power converting module 103 is coupled with the power supply 20 through the switching module 101. The signal inputting terminal Ns of the power converting module 103 is coupled with the signal processing module 102. The power outputting terminal No of the power converting module 103 is coupled with the lighting device 30. When the switching module 101 is closed, the power converting module 103 transfers electric power to the lighting device 30. When the switching module 101 is opened, the power converting module 103 cuts off the electric power of the lighting device 30. Accordingly, in this present embodiment, the power converting module 103 is capable of selectively converting electric power to the lighting device 30 for controlling the illuminating state of the lighting device 30. When the switching module 101 is opened, the power converting module 103 is unable to receive the supply power Vdd1 from the power supply 20, and the lighting device 30 is unable to generate light. When the switching module 101 is closed, the power converting module 103 receives the supply power Vdd1 from the power supply 20, and the power converting module 103 is able to process and convert the supply power Vdd1 for the lighting device 30. For example, the power converting module 103 may perform a filtering process and a voltage regulating process upon the supply power Vdd1, and output the regulated supply power Vdd2 to the lighting device 30 for driving the lighting device 30. Accordingly, the lighting device 30 may steadily operate under the corresponding illuminating state. Therefore, the present embodiment, e.g. the power converting module 103, provides a relatively easy way for user to selectively power-up or power-down the lighting device 30.
The signal processing module 102 is arranged to output the adjusting signal Sa to the signal inputting terminal Ns of the power converting module 103. The power converting module 103 changes the illuminating mode of the lighting device 30 according to the adjusting signal Sa. Accordingly, the brightness and the color of the lighting device 30 may be adjusted. The operating state of the power converting module 103 is changed by the adjusting signal Sa. The relationship between the illuminating mode of the lighting device 30 and the number of signals continuously triggered on the switching module 101 may be obtained through the adjusting signal Sa. The power converting module 103 obtains the light switching information according to the adjusting signal Sa. As the illuminating state of the lighting device 30 may be changed by the adjusting signal Sa, the color and the brightness of the lighting device 30 may be adjusted or changed by user through the adjusting signal Sa. Therefore, the lighting device 30 may be intelligently controlled by the lighting device controlling circuit 10.
In addition, the power converting module 103 may comprise a microcontroller and a rectifying circuit. For example, the microcontroller may be included in MCS-51 microcontroller family, wherein the microcontroller may analyze and process the adjusting signal Sa such that the lighting device 30 may switch among different illuminating modes. The rectifying circuit may comprise a rectifier bridge. When the switching module 10 is closed, the rectifier bridge may rectify the power supply such that the lighting device 30 may receive a stable supply power Vdd2. Accordingly, the lighting device controlling circuit 10 is not only structurally simple and low cost, and the lighting device controlling circuit 10 also increase the stability and safety of the lighting device 30.
In this embodiment, the lighting device controlling circuit 10 receives the button message of user through the switching module 101 for changing the luminous effects of the lighting device 30. Therefore, the lighting device controlling circuit 10 improves the interaction between human and machine through the button message. Without using additional sensor or software, the lighting device controlling circuit 10 may intelligently control the lighting device 30. The lighting device controlling circuit 10 may greatly simplify the luminous control of the lighting device 30. The lighting device controlling circuit 10 changes the illuminating mode of the lighting device 30 through the power converting module 103 for improving the user experience. In this embodiment, the lighting device controlling circuit 10 has a relatively high responding speed of controlling the lighting device 30 and a relatively low manufacturing cost. In comparison the related arts, which have the complex design and complex operating steps, the illuminating state of the lighting device 30 is more easily to be controlled by using the present lighting device controlling circuit 10.
In one embodiment, the power supply 20 is domestic power. The domestic power may be the general-purpose alternating-current (AC) electric power supply. The electrical power of the domestic power is delivered to homes and businesses. The voltage and frequency of the domestic power differ between regions. For example, a voltage of 230 V and a frequency of 50 Hz are used in Europe. In North America, the most common combination is 120 V and a frequency of 60 Hz.
In another embodiment, the power supply 20 is direct current (DC) power. The voltage level of the DC power may be any voltage falling within the range 160V-220V.
When the power supply 20 is the domestic power, the lighting device controlling circuit 10 may receive the domestic power, and the power converting module 103 may convert the electric power of the domestic power into a stable output power. The power converting module 103 may output the stable output power to the lighting device 30 for steadily driving the lighting device 30. The lighting device controlling circuit 10 may change the illuminating mode of the lighting device 30. Therefore, the manipulation of the lighting device controlling circuit is improved. In this embodiment, the lighting device controlling circuit 10 may be applied in various industrial fields due to its great compatibility.
The switching module 101 is coupled between the live wire L and the power inputting terminal of the power converting module 103. However, this is not a limitation of the present invention. In another embodiment, the switching module 101 may be coupled between the neutral wire N and the power inputting terminal of the power converting module 103.
The switching module 101 may change the state of the power inputting to the lighting device controlling circuit 10 such that the lighting device controlling circuit 10 selectively provide power to the lighting device 30. In this embodiment, the live wire L and the neutral wire N are configured to be able to provide the corresponding supply power Vdd1. The switching module 101 may be coupled to the power transmitting line in the live wire L. The switching module 101 may also be coupled to the power transmitting line in the live wire N in another embodiment. The switching module 101 may open or close the connection between the live wire L and the power converting module 103. Accordingly, in this embodiment, the circuit structure of the switching module 101 is more compatible to other system and has better user experience. Therefore, the lighting device controlling circuit 10 may be applied in various application fields.
In another embodiment as shown in
The first switching module 1011 is connected between the live wire L and the power inputting terminal of the power converting module 103. The second switching module 1012 is connected between the neutral wire N and the power inputting terminal of the power converting module 103.
In this embodiment, the connectivity of the lighting device controlling circuit 10 is implemented by the switching modules 1011 and 1012. Specifically, the power inputting terminal Ni of the power converting module 103 may conduct the supply power Vdd1 to the lighting device 30 only when both of the first switching module 1011 connected to the power transmitting line of the live wire L and the second switching module 1012 connected to the power transmitting line of the neutral wire N are closed. Therefore, when both of the switching modules 1011 and 1012 are closed, the lighting device 30 may generate light and change the illuminating state. If one of the switching module 1011 and the switching module 1012 connected to the power transmitting line of the neutral wire N is opened, the lighting device 30 may loss the electric energy. Accordingly, in this embodiment, the two switching modules 1011 and 1012 may guarantee the stability of the lighting device controlling circuit 10. Moreover, the two switching modules 1011 and 1012 may protect the lighting device 30 from the external interference signal such that the lighting device 30 may have stable illuminating state. Accordingly, the controlling performance of the lighting device controlling circuit 10 is increased, and the illuminating error of the lighting device 30 is reduced.
In another embodiment, the power converting module 103 switches the illuminating mode of the lighting device 30 according to the adjusting signal Sa. The following paragraphs describe the detailed operation of this embodiment.
The power converting module 103 is arranged to obtain the relationship between the illuminating state of the lighting device 30 and the number of triggering signals continuously triggered on the switching module 101 as well as 1011 according to the adjusting signal Sa. The power converting module 103 is arranged to switch the illuminating mode of the lighting device 30 according to the obtained relationship.
As mentioned in the above paragraph, the number of triggering signals continuously triggered on the switching module 101 as well as 1011 corresponds to the function selected by user. For example, the power converting module 103 may control the lighting device 30 to have different illuminating modes (e.g. different color and brightness) when the continuous triggering numbers on the switching module 101 are three and four respectively. Accordingly, the power converting module 103 may obtain the illuminating state of the lighting device 30 through the adjusting signal Sa. Then, the power converting module 103 may obtain the command of switching operation according to the relationship. The power converting module 103 is arranged to adjust the light color and brightness of the lighting device 30 according to the relationship. Accordingly, the lighting device controlling circuit 10 may achieve good controlling performance through the power converting module 103. In this embodiment, the lighting device controlling circuit 10 may switch the illuminating mode of the lighting device 30 in real time.
In another embodiment as shown in
The signal detecting unit 1021 is coupled with the switching module 101. The signal detecting unit 1021 is arranged to count the number of triggering signals continuously triggered on the switching module 101, and to convert the number into the adjusting signal Sa accordingly.
The signal converting unit 1022 is coupled between the signal detecting unit 1021 and the signal inputting terminal of the power converting module 103. The signal converting unit 1022 is arranged to convert the adjusting signal Sa into a digital format from an analog format.
In this embodiment, the signal detecting unit 1021 is arranged to have the function of sampling signal. The signal detecting unit 1021 is capable of detecting if the switching module 101 is triggered. When the switching module 101 is triggered, the operating state of the lighting device controlling circuit 10 is changed accordingly. The signal detecting unit 1021 is capable of detect and store the number of triggering signals continuously triggered on the switching module 101, and to generate the adjusting signal Sa corresponding to the triggering number. In other words, the selected function of user may be obtained from the adjusting signal Sa. Accordingly, the lighting device controlling circuit 10 may accurately control the lighting device 10 through the adjusting signal Sa.
The signal converting unit 1022 is capable of converting signal between analog signal and digital signal. When the adjusting signal Sa is outputted by the signal detecting unit 1021, the power converting module 103 is unable to read or identify the adjusting signal Sa. The signal converting unit 1022 is arranged to convert the adjusting signal Sa into the digital signal from the analog signal. When the power converting module 103 receives the adjusting signal Sa in digital format, the power converting module 103 may directly receive the message of the selected function from user. The signal converting unit 1022 is capable of preventing the adjusting signal Sa from distortion and losing power during the transmission process. Accordingly, the efficiency of signal transmission of the lighting device controlling circuit 10 is improved. Moreover, the adjusting signal Sa may timely drive the power converting module 103 for changing the illuminating mode of the lighting device 30. Therefore, the responding speed of the lighting device controlling circuit 10 is increased such that the lighting device controlling circuit 10 may always operate under a stable state.
It should be noted that, in this embodiment, the signal converting unit 1022 may be implemented by an analog-to-digital converter (ADC). For example, the ADC may comprise: at least one switch, at least one comparator, and other electronic units. The ADC is arranged to convert an analog signal into a digital value for protecting the transmitting quality of the adjusting signal Sa. Accordingly, the lighting device controlling circuit 10 is capable of controlling the illuminating state of the lighting device 30. The lighting device controlling circuit 10 also has great compatible performance.

The second terminal of the second resistor R2, the anode of the second diode D2, and the second terminal of the first capacitor C1 are connect to the ground GND.
In

A terminal of the wall switch is connected with the power supply 20, and the other end of the wall switch is connected to the signal processing module 102 and the power converting module 103.
In another embodiment, the wall switch is BK02 switch. However, this is not a limitation of the present invention. A person skill in the art may use another wall switch model to control the open/close between the power supply 20 and the power converting module 103. Accordingly, the lighting device controlling circuit 10 has good compatible performance.
The wall switch has relatively low manufacturing cost and wide application field. The wall switch also has long lifetime. In this embodiment, the wall switch may receive the button message or button signal from user in real time. The lighting device controlling circuit 10 may change the light function according to the number of triggering signals continuously touched on the wall switch by user. Accordingly, the wall switch may improve the interaction between user and machine. The lighting device controlling circuit 10 may change the illuminating mode of the lighting device 30 in real time, and the user experience is improved. The lighting device controlling circuit 10 also has low manufacturing cost and low application cost. The operation of the lighting device 30 is relatively simple and the lighting device 30 is more compatible to other system.
In an embodiment, the illuminating mode of the lighting device 30 comprises a first illuminating mode and a second illuminating mode. The operation of the power converting module 103 is selectively switching between the first illuminating mode and the second illuminating mode according to the adjusting signal Sa.
When the power converting module 103 is operated under the first illuminating mode, the luminance of the lighting device 30 is the first luminance and the color of the lighting device 30 is the first light color. When the power converting module 103 is operated under the second illuminating mode, the luminance of the lighting device 30 is the second luminance and the color of the lighting device 30 is the second light color. The second luminance and the second light color are different from the first luminance and the first light color respectively.
In this embodiment, the power converting module switches the illuminating mode of the lighting device 30 according to the adjusting signal Sa. The lighting device 30 has different brightness and different colors under different illuminating modes. For example, the first light color is red color and the second light color is blue color. The first luminance is 120 candela (cd) and the second luminance is 150 candela. For example, when the power converting module 103 receives the adjusting signal Sa, the power converting module 103 may control the lighting device 30 to enter the second illuminating mode from the first illuminating mode, or to enter the first illuminating mode from the second illuminating mode. Accordingly, by using the adjusting signal Sa, the power converting module 103 may arbitrarily switch or change the illuminating mode of the lighting device 30. The lighting device 30 may produce the corresponding luminous effects according to the button message from user such that the user may feel the good visual experience. Moreover, the luminous effects of the lighting device 30 may be easily controlled by the lighting device controlling circuit 10.
In one embodiment, the lighting device 30 comprises at one light bead. In another embodiment, the lighting device 30 comprises a plurality of serially connected light beads.

Accordingly, the cost of controlling the lighting device 30 is reduced. Moreover, the number of the light beads of the lighting device 30 may be arbitrary decided by user. Therefore, the lighting device controlling circuit 10 may be applied in various industrial fields.
