Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more specifically to a method for controlling a lamp. Background Technology

[0002] Festive string lights, with their diverse shapes and flashing lights, provide decorative illumination at night and are a top choice for adding to the festive atmosphere. These lighting effects are achieved by a controller sending duty cycle control signals to the LED lights, causing them to produce various flashing effects.

[0003] Existing LED light controllers include a control unit and a switching unit. The switching unit is connected to the output of the control unit, which is typically a programmable chip. The switching unit uses four transistors to form two sets of switching circuits. A control module controls these two sets of switching circuits to alternately conduct, thus achieving the alternating flashing of two LED strings connected to the output. The above two sets of switching circuits have the following problems:

[0004] First, it can only connect two loads, and each load is usually a string of lights. Therefore, the number of light strings that the existing switching unit can connect is limited, which restricts the lighting effect produced during operation.

[0005] Secondly, when one of the switching circuits fails, the light string connected to that switching circuit will not work. At this time, only the other switching circuit can work, and the light string effect will become worse.

[0006] Third, the four transistors in the aforementioned switching unit are arranged in pairs diagonally to form a switching circuit. This structure leads to a complex circuit, requiring more wiring and increasing costs. Furthermore, in each switching circuit, only one transistor is electrically connected to the control module. This means that in each switching circuit, only one transistor is controlled by the control module to conduct or turn off; the conduction or turn-off of the other transistor depends on the state of the previous transistor, resulting in the other transistor not being able to be controlled independently.

[0007] Fourth, the aforementioned control unit can usually only switch the flashing mode of the light and has no other functions. Therefore, the aforementioned controller has the defect of being single-function. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention provides a method for controlling a lighting fixture. This invention can switch the flashing mode of the light and set the working time of the light.

[0009] The technical solutions to the above technical problems are as follows:

[0010] The method for controlling the lighting fixtures includes the following steps:

[0011] S1, after power-on, the control unit outputs a control signal, and the control unit receives a switching signal input from the mode selector;

[0012] S2, if the control unit determines that the switching signal input by the mode selector is a light flashing mode switching signal, the control unit outputs a flashing mode switching control signal to the switching unit, and the flashing mode switching control signal controls the order of the switching unit being turned on or off.

[0013] S3, if the control unit determines that the switching signal input by the mode selector is a light timing signal, the control unit controls the operation of outputting the timing control signal according to the input of the mode selector. When the timing time ends, the control unit stops outputting the control signal.

[0014] The control method for the lamp is as follows: after power-on, the control unit outputs a control signal to make the lamp work. If the control unit receives a timing switching signal from the mode selector, the control unit switches the operation of outputting the timing control signal according to the input of the mode selector. When the timing time ends, the control unit stops outputting the control signal.

[0015] This invention sends operation signals to the control unit in different ways. The control unit identifies the input signals and determines whether they are for switching the light flashing mode or setting the light's operating time. After reaching a specific conclusion, the control unit outputs corresponding control commands to control the lamp's operation. Therefore, this invention can both switch the light flashing mode and set the light's operating time, making its functionality multifaceted. Attached Figure Description

[0058] Example 1

[0059] like Figure 1 As shown, the lighting controller of this embodiment includes a DC power supply 1, a control unit 2, and a switching unit 3 controlled by the control unit 2 to turn on or off. The following is a detailed description of each part and the relationships between them:

[0060] like Figure 1 and 2 As shown, the output terminals of DC power supply 1 are electrically connected to control unit 2 and switching unit 3, respectively. DC power supply 1 can be a battery or a switching power supply. In this embodiment, a switching power supply that converts AC to DC is preferred. In this embodiment, the switching power supply includes a rectifier and filter circuit, a voltage conversion circuit, a startup circuit, and a switching control circuit. Each part of the switching power supply is described in detail below:

[0061] like Figure 2As shown, the output terminals of the rectifier and filter circuit are connected to the voltage conversion circuit and the starting circuit, respectively. The rectifier and filter circuit includes a single-phase full-wave rectifier circuit BD1, a first inductor L1, a first capacitor C1, a second capacitor C2, a second parallel capacitor C2B, a second inductor L2, a first anti-interference resistor R0A, and a second anti-interference resistor R0B. The single-phase full-wave rectifier circuit consists of four diodes. The positive output terminal of the single-phase full-wave rectifier circuit BD1 is connected to one end of the first inductor L1 and one end of the first capacitor C1. The first anti-interference resistor R0A is connected in parallel across the two ends of the first inductor L1. The other end of the first inductor L1 is connected to one end of the second capacitor C2, and the other end of the second capacitor C2 is grounded. The second parallel capacitor C2B is connected in parallel across the two ends of the second capacitor C2. The other end of the first capacitor C1 is connected to the negative output terminal of the single-phase full-wave rectifier circuit BD1. The other end of the first capacitor C1 is also connected to one end of the second inductor L2, and the other end of the second inductor L2 is grounded. The second anti-interference resistor R0B is connected in parallel across the two ends of the second inductor L2.

[0062] like Figure 2 As shown, the AC voltage is supplied to the single-phase full-wave rectifier circuit BD1 through fuse RF1 for rectification. Then, it is filtered by the first inductor L1, the first capacitor C1, the second capacitor C2, and the second parallel capacitor C2B. Electromagnetic interference is eliminated by an electromagnetic interference suppression circuit formed by the first inductor L1, the first anti-interference resistor R0A, the second inductor L2, and the second anti-interference resistor R0B, preventing electromagnetic interference signals from affecting the DC output voltage. The DC voltage obtained after rectification and filtering is sent to the voltage conversion circuit, which is transformer T1, to convert the high voltage to a low voltage for use by the subsequent control unit 2 and switching unit 3. A safety capacitor CY1 is installed between transformer T1 and the first inductor L1, with one end of the safety capacitor CY1 connected to ground.

[0063] like Figure 2 As shown, the switching power supply also includes a rectifier diode D7 and a fifth capacitor C5. The anode of the rectifier diode D7 is connected to the output terminal of the voltage conversion circuit, and the cathode of the rectifier diode D7 is connected to one end of the fifth capacitor C5. The other end of the fifth capacitor C5 is grounded. The secondary output voltage of transformer T1 is rectified by the rectifier diode D7 to obtain a DC voltage, which is the output terminal V+ of DC power supply 1. The DC voltage charges the fifth capacitor C5.

[0064] like Figure 2 As shown, the startup circuit includes a first current-limiting resistor R9 and a second current-limiting resistor R10. One end of the first current-limiting resistor R9 is connected to the other end of the first inductor L1, and the other end of the first current-limiting resistor R9 is connected to one end of the second current-limiting resistor R10. The other end of the second current-limiting resistor R10 is electrically connected to the switch control circuit.

[0065] like Figure 2 As shown, the switch control circuit is electrically connected to the rectifier filter circuit and the voltage conversion circuit, respectively. The switch control circuit includes a power control chip U1, a second resistor R2, a third capacitor C3, a first voltage sampling resistor R8, a second voltage sampling resistor R4, and a voltage sampling filter capacitor C0. The output terminal of the power control chip U1 is connected to the transformer T1, and the power control chip U1 is also grounded through the second resistor R2. One end of the third capacitor C3 is connected to the other end of the second current-limiting resistor R10 and the power control chip U1, and the other end of the third capacitor C3 is grounded. The auxiliary winding of the transformer T1 is connected to the third capacitor C3 through the fifth diode D5. One end of the first voltage sampling resistor R8 is connected to the auxiliary winding of the transformer T1, and the other end of the first voltage sampling resistor R8 is connected to the second voltage sampling resistor R4 and the power control chip U1.

[0066] like Figure 2 As shown, in the initial stage of power-on of the switching power supply, the current output from the rectifier and filter circuit is limited by the first current-limiting resistor R9 and the second current-limiting resistor R10 before being supplied to the third capacitor C3 to charge it. The voltage released by the third capacitor C3 is supplied to the power control chip U1, which then powers the switching control circuit. The electrical signal from the primary winding of transformer T1 is sampled by the first voltage sampling resistor R8 and the second voltage sampling resistor R4 and then supplied to the power control chip U1. The power control chip U1 compares this electrical signal with the output voltage value set internally. If the two are not equal, the power control chip U1 outputs a control signal to adjust the output voltage. The power control chip U1 integrates a power transistor, and adjusts the output voltage by controlling the switching time of the power transistor.

[0067] like Figure 2 As shown, a reverse peak absorption circuit is also connected between the switch control circuit and the transformer T1. The reverse peak absorption circuit includes a fourth capacitor C4, a sixth resistor R6, and a sixth diode D6. One end of the fourth capacitor C4 is connected to the other end of the first inductor L1, and the other end of the fourth capacitor C4 is connected to the cathode of the sixth diode D6. The anode of the sixth diode D6 is connected to the output terminal of the power control chip U1, and the sixth resistor R6 is connected in parallel across the fourth capacitor C4.

[0068] like Figure 3 As shown, the control unit 2 includes a microcontroller U2, a clock circuit, and a memory chip U3. The microcontroller U2 is connected to the output terminal V+ of the DC power supply. The microcontroller U2 is an MCU. Since the microcontroller U2 is a programmable controller, when the mode selector sends an operation signal to the microcontroller U2 according to the programmed rules, the microcontroller U2 issues a control signal to make the lamp 3a work.

[0069] like Figure 3 As shown, in this embodiment, a preferred approach is to provide a voltage regulator and filter circuit between the output terminal V+ of the DC power supply 1 and the microcontroller U2. This voltage regulator and filter circuit includes a twelfth resistor R12, a Zener diode ZD1, and a sixth capacitor C6. One end of the twelfth resistor R12 is connected to the output terminal V+ of the DC power supply, and the other end of the twelfth resistor R12 is connected to the cathode of the Zener diode ZD1. The anode of the Zener diode ZD1 is grounded. One end of the sixth capacitor C6 is connected to the cathode of the Zener diode ZD1, and the other end of the sixth capacitor C6 is grounded. Pin 5 of the microcontroller U2 is connected to one end of the sixth capacitor C6.

[0070] like Figure 3 As shown, the clock circuit includes a crystal oscillator XL1, a twelfth capacitor C12, and a thirteenth capacitor C13. The two ends of the crystal oscillator XL1 are connected to pins 6 and 7 of the microcontroller U2, respectively. One end of the twelfth capacitor C12 is connected to one end of the crystal oscillator XL1, and the other end of the twelfth capacitor C12 is grounded. One end of the thirteenth capacitor C13 is connected to the other end of the crystal oscillator XL1, and the other end of the thirteenth capacitor C13 is grounded.

[0071] like Figure 3 As shown, pin 8 of memory chip U3 is connected to the output terminal V+ of the DC power supply. After setting up the voltage regulation and filtering circuit, it is preferable that pin 8 of memory chip U3 is connected to one end of the sixth capacitor C6. Pins 1 to 4 and pin 7 of memory chip U3 are grounded. Pin 5 of memory chip U3 is connected to pin 1 of microcontroller U2, and pin 6 of memory chip U3 is connected to pin 2 of microcontroller U2. Microcontroller U2 outputs the current operating mode to memory chip U3, and memory chip U3 records the operating mode. When the power is off, memory chip U3 still records the operating mode before microcontroller U2 stopped working. When microcontroller U2 is powered on again, microcontroller U2 reads the recorded operating mode from memory chip U3 and then sends a control signal to the load lamp 3a in that operating mode. In addition to being configured externally to microcontroller U2 as described above, memory chip U3 can also be built into microcontroller U2. Of course, memory chip U3 is not mandatory; it can be connected as needed.

[0072] like Figure 3 As shown, the switching unit 3 in this embodiment includes three sets of switching circuits. Each set of switching circuits includes a load connection part and two first switching transistors and second switching transistors independently controlled by the control unit. The first switching transistor and the second switching transistor can be transistors or MOSFETs. In this embodiment, transistors are used as an example for explanation. The first switching transistor is substituted for the first transistor, and the second switching transistor is substituted for the second transistor.

[0073] The base of the first transistor is connected to the output terminal of the control unit 2. The emitter of the first transistor is used to connect to a DC power supply. The collector of the first transistor is connected to the collector of the second transistor. The base of the second transistor is connected to the output terminal of the control unit 2. The emitter of the second transistor is grounded. The load connection part is located at the connection part between the collector of the first transistor and the collector of the second transistor.

[0074] like Figure 3 As shown, in this embodiment, the first transistor Q3 in the first group of switching circuits is a PNP transistor or a P-channel MOSFET, and the second transistor Q4 in the first group of switching circuits is an NPN transistor or an N-channel MOSFET. The base of the first transistor Q3 in the first group of switching circuits is connected to pin 10 of the microcontroller U2. The base of the first transistor Q3 in the first group of switching circuits is preferentially connected to pin 10 of the microcontroller U2 through the first current-limiting resistor RA1. The emitter of the first transistor Q3 in the first group of switching circuits is connected to the output terminal V+ of the DC power supply. The base of the second transistor Q4 in the first group of switching circuits is connected to pin 16 of the microcontroller U2. The base of the second transistor Q4 in the first group of switching circuits is preferentially connected to pin 16 of the microcontroller U2 through the second current-limiting resistor RB1. The emitter of the second transistor Q4 in the first group of switching circuits is grounded. The load connection part A in the first group of switching circuits is connected to the first transistor Q3 in the first group of switching circuits. The collector of the transistor is connected to the collector of the second transistor Q4 in the first set of switching circuits.

[0075] like Figure 3 As shown, in the second set of switching circuits, the first transistor Q2 is a PNP transistor or a P-channel MOSFET, and the second transistor Q5 is an NPN transistor or an N-channel MOSFET. The base of the first transistor Q2 in the second set of switching circuits is connected to pin 11 of the microcontroller U2. The base of the transistor is preferentially connected to pin 11 of the microcontroller U2 through the third current-limiting resistor RA2. The emitter of the first transistor Q2 in the second set of switching circuits is connected to the output terminal V+ of the DC power supply. The base of the second transistor Q5 in the second set of switching circuits is connected to pin 15 of the microcontroller U2. The base of the second transistor Q5 in the second set of switching circuits is preferentially connected to pin 15 of the microcontroller U2 through the fourth current-limiting resistor RB2. The emitter of the second transistor Q5 in the second set of switching circuits is grounded. The load connection part B in the second set of switching circuits is connected to the connection part between the collector of the first transistor Q2 in the second set of switching circuits and the collector of the second transistor Q5 in the second set of switching circuits.

[0076] like Figure 3As shown, the first transistor Q1 in the third group of switching circuits is a PNP transistor or a P-channel MOSFET, and the second transistor Q6 in the third group of switching circuits is an NPN transistor or an N-channel MOSFET. The base of the first transistor Q1 in the third group of switching circuits is connected to pin 13 of the microcontroller U2. The base of transistor Q1 in the third switching circuit is connected to pin 13 of microcontroller U2 via the fifth current-limiting resistor RA3. The emitter of transistor Q1 in the third switching circuit is connected to the output terminal V+ of the DC power supply. The base of transistor Q6 in the third switching circuit is connected to pin 14 of microcontroller U2. The base of transistor Q6 in the third switching circuit is connected to pin 14 of microcontroller U2 via the sixth current-limiting resistor RB3. The emitter of transistor Q6 in the third switching circuit is grounded. The load connection C in the third switching circuit is connected to the connection between the collector of transistor Q1 and the collector of transistor Q6 in the third switching circuit.

[0077] like Figure 3 As shown, taking the first group of switching circuits as an example, the working process of the first group of switching circuits will be explained in the following cases:

[0078] (1) When pins 10 and 16 of the microcontroller U2 both output high level, the first transistor Q3 in the first group of switching circuits is turned off, and the second transistor Q4 in the first group of switching circuits is turned on. The level of the connection between the collector of the first transistor Q3 and the collector of the second transistor Q4 in the first group of switching circuits is equal to ground, which is low level. At this time, the level of the load connection A in the first group of switching circuits is low level.

[0079] (2) When pins 10 and 16 of the microcontroller U2 both output a low level, the first transistor Q3 in the first group of switching circuits is turned on and the second transistor Q4 in the first group of switching circuits is turned off. The level of the connection between the collector of the first transistor Q3 and the collector of the second transistor Q4 in the first group of switching circuits is the output terminal V+ of the DC power supply, which is a high level. At this time, the level of the load connection A in the first group of switching circuits is a high level.

[0080] (3) When pin 10 of microcontroller U2 outputs a high level and pin 16 of microcontroller U2 outputs a low level, the first transistor Q3 in the first group of switching circuits is turned off, the second transistor Q4 in the first group of switching circuits is turned off, and there is no output at the connection between the collector of the first transistor Q3 in the first group of switching circuits and the collector of the second transistor Q4 in the first group of switching circuits.

[0081] (4) When pin 10 of microcontroller U2 outputs a low level and pin 16 of microcontroller U2 outputs a high level, the first transistor Q3 in the first group of switching circuits is turned on and the second transistor Q4 in the first group of switching circuits is turned on. The current from the output terminal V+ of the DC power supply flows directly to ground, which will cause the first group of switching circuits to short circuit. This situation is not allowed to occur.

[0082] like Figure 3 As shown, since the load connection parts of the three sets of switching circuits can all output high or low levels and control the duty cycle of each switching circuit output, and according to the circuit structure of the load lamp 3a, the load lamp 3a can present different flashing modes.

[0083] like Figure 3 and 4 As shown, the lamp 3a in this embodiment includes: a first wire 4, a second wire 5, a third wire 6, a first LED lamp 7, a second LED lamp 8, a third LED lamp 9, and a fourth LED lamp 10. The first wire 4 is connected to the load connection part A of the first group of switching circuits, the second wire 5 is connected to the load connection part B of the second group of switching circuits, and the third wire 3 is connected to the load connection part C of the third group of switching circuits.

[0084] like Figure 3 and 4 As shown, the anode of the first LED lamp 7 is connected to the first wire 4, and the cathode of the first LED lamp 7 is connected to the second wire 5; the cathode of the second LED lamp 8 is connected to the first wire 4, and the anode of the second LED lamp 8 is connected to the second wire 5; the cathode of the third LED lamp 9 is connected to the second wire 5, and the anode of the third LED lamp 9 is connected to the third wire 6; the anode of the fourth LED lamp 10 is connected to the second wire 5, and the cathode of the fourth LED lamp 10 is connected to the third wire 6.

[0085] like Figure 3 and 4 As shown, based on the circuit structure of the aforementioned lamp 3a, its operation is divided into the following states:

[0086] (1), such as Figure 3 and 4 As shown, the load connection part A of the first group of switching circuits outputs a high level, while the load connection parts B of the second group of switching circuits and the load connection parts C of the third group of switching circuits output a low level, causing the first LED lamp 7 to work and the remaining LED lamps to turn off.

[0087] (2), such as Figure 3 and 4As shown, the load connection part A of the first group of switching circuits outputs a low level, while the load connection parts B of the second group of switching circuits and the load connection parts C of the third group of switching circuits output a high level, causing the second LED lamp 8 to work and the other LED lamps to turn off.

[0088] (3), such as Figure 3 and 4 As shown, the load connection part A of the first group of switching circuits and the load connection part B of the second group of switching circuits output a low level, and the load connection part C of the third group of switching circuits outputs a high level, so that the third LED lamp 9 works and the other LED lamps are turned off.

[0089] (4), such as Figure 3 and 4 As shown, the load connection part A of the first group of switching circuits and the load connection part B of the second group of switching circuits output a high level, and the load connection part C of the third group of switching circuits outputs a low level, so that the fourth LED lamp 10 is working and the other LED lamps are turned off.

[0090] like Figure 3 and 4 As shown, the three wires and four light fixtures constitute a three-wire, four-way light fixture 3a. However, the light fixture 3a in this embodiment is not limited to this; for example, as... Figure 5 As shown, the lighting fixture also includes a fifth LED lamp 11 and a sixth LED lamp 12. The anode of the fifth LED lamp 11 is connected to the first conductor 4, and the cathode of the fifth LED lamp 11 is connected to the third conductor 6. The cathode of the sixth LED lamp 12 is connected to the first conductor 4, and the anode of the sixth LED lamp 12 is connected to the third conductor 6. Based on a three-wire, four-path system, the addition of the fifth LED lamp 11 and the sixth LED lamp 12 creates a three-wire, six-path lighting fixture.

[0091] like Figure 3 and 4 As shown, any of the above methods can control the duty cycle and the working time of each LED lamp. Different working times produce different lighting effects. Furthermore, this embodiment connects to the controller via three wires, and at least four LED lamps are connected between these three wires. Obviously, the lighting effect is better than that of the prior art. Moreover, even with a larger number of connected lamps compared to the prior art, both the controller structure and the circuit structure are relatively simple, thus not increasing the cost. In addition, the two transistors in each switching circuit are controlled by the microcontroller U2, which determines whether the output level of the switching circuit is high or low. This provides independent control for each transistor, avoiding the situation in the prior art where the conduction of one transistor is determined by the other transistor, thereby improving the control efficiency of the controller.

[0092] like Figure 3 As shown, in low-light environments, it is difficult to locate the lighting controller. Therefore, in this embodiment, a preferred approach is to include an indicator LED2 that remains constantly lit after power-on to indicate the controller's location. The indicator LED2 is electrically connected to the output terminal of the DC power supply 1, specifically, the output terminal V+ of the DC power supply is connected to the indicator LED2. As long as the DC power supply output terminal V+ has a working voltage, the indicator LED2 will remain lit to indicate the specific location of the lighting controller. In this embodiment, a nineteenth current-limiting resistor R19 is connected between the indicator LED2 and the twelfth resistor R12. The nineteenth current-limiting resistor R19 reduces the current reaching the indicator LED2, preventing damage to the indicator LED2.

[0093] like Figure 3 As shown, since the microcontroller U2 has multiple built-in flashing modes, sending a flashing mode switching signal to the microcontroller U2 will cause the microcontroller U2 to output different control signals. For example, it can control the high or low level output of each group of switching circuits, or control the duty cycle of the output signals of each group of switching circuits, to achieve different flashing modes. Of course, the working time of the lamp 3a can also be controlled by selection, such as working within a specified working time period, or stopping working within a specified working time period.

[0094] like Figure 3 As shown, based on the above, this embodiment also includes a mode selector that inputs a light flashing mode switching signal or a light timing signal to the control unit 2. This mode selector is electrically connected to the control unit. The mode selector can be operated in wired or wireless mode. In wired mode, the mode selector is directly soldered to the control unit 2. In wireless mode, a portion of the mode selector is directly soldered to the control unit 2, while the other portion communicates with the control unit 2 via wireless signal transmission.

[0095] like Figure 3 As shown, in this embodiment, the mode selector uses a push-button switch SW or a touch switch (not shown in the figure). The push-button switch SW or the touch switch is electrically connected to the control unit 2. In this embodiment, one end of the push-button switch SW is preferably soldered to pin 8 of the microcontroller U2, and the other end of the push-button switch SW is grounded.

[0096] like Figure 3As shown, in this embodiment, a wireless signal receiver U4 is also used. One end of the wireless signal receiver U4 is soldered to pin 5 of the microcontroller U2, and the other end of the wireless signal receiver U4 is soldered to pin 9 of the microcontroller U2. A wireless signal transmitter paired with the wireless signal receiver U4 is not shown in the figure. The wireless signal transmitter is typically a handheld remote control. The wireless signal transmitter and the wireless signal receiver U4 communicate via infrared signals. After receiving the signal sent by the wireless signal transmitter, the wireless signal receiver U4 uses it to change the flashing mode or timing signal of the lamp 3a.

[0097] like Figure 3 As shown, to facilitate determining whether lamp 3a is in a timing state, this embodiment further includes: a timing indicator LED1, which is activated by control unit 2 based on the input of the mode selector to indicate the timing status after the lamp timing is activated. The timing indicator LED1 is electrically connected to control unit 2. The timing indicator LED1 is a light-emitting diode (LED), with one end connected to pin 4 of microcontroller U2 and the other end grounded through an eighteenth resistor. When the timing is activated, control unit 2 outputs a signal to illuminate the timing indicator LED1; when the timing ends, control unit 2 outputs a signal to extinguish the timing indicator LED1.

[0098] The switching unit 2 in the above embodiment 1 can, in addition to being able to, interact with Figure 4 In addition to connecting to the 3a three-wire four-way lighting fixture, it can also be connected to... Figure 5 The three-wire, six-way lighting fixture 3a is shown in the diagram. Additionally... Figure 4 or Figure 5 The light strings shown can be used in conjunction with [other devices] in actual applications. Figures 11a to 36f Connect any one of them.

[0099] Example 2

[0100] like Figure 6 As shown, the second type of control unit 2 and switch unit 3 in this invention have the same structure as the DC power supply 1 in the above embodiment 1, and will not be described again here.

[0101] The output terminal V+ of DC power supply 1 is electrically connected to the switching unit 3. The switching unit 3 includes a first switching group, a second switching group, and a control module U1A that controls the alternating conduction of the first and second switching groups. The output terminal of the control module U1A is electrically connected to the first switching group, and the output terminal of the control module U1A is electrically connected to the second switching group to form a second switching circuit.

[0102] The difference between this embodiment and Embodiment 1 is that the voltage regulator and filter circuit is set between the output terminal V+ of the DC power supply and the control module U1A. That is, one end of the twelfth resistor R12 in the voltage regulator and filter circuit is connected to the output terminal V+ of the DC power supply, the other end of the twelfth resistor R12 is connected to the cathode of the Zener diode ZD1, the anode of the Zener diode ZD1 is grounded, one end of the sixth capacitor C6 is connected to the cathode of the Zener diode ZD1, the other end of the sixth capacitor C6 is grounded, and pin 1 of the microcontroller U2 is connected to one end of the sixth capacitor C6.

[0103] In this embodiment, the second switch group includes a ninth transistor Q9 and a thirteenth transistor Q10. The base of the ninth transistor Q9 is connected to the output terminal of the control module U1A, which is a chip. The base of the ninth transistor Q9 is connected to pin 6 of the control module U1A through the thirteenth resistor R13. The base of the ninth transistor Q9 is also connected to one end of a twenty-first capacitor C21, and the other end of the twenty-first capacitor C21 is grounded. The emitter of the ninth transistor Q9 is grounded. The collector of the ninth transistor Q9 is connected to the base of the thirteenth transistor Q10 and the output terminal of the DC power supply 1. A sixteenth resistor R16 is connected between the ninth transistor Q9 and the output terminal V+ of the DC power supply 1. A sixteenth current-limiting resistor R16B is connected between the base of the thirteenth transistor Q10 and the output terminal V+ of the DC power supply 1. The emitter of the thirteenth transistor Q10 is connected to the output terminal V+ of the DC power supply 1. The collector of the thirteenth transistor Q10 is the output terminal of the second switch circuit. Based on the above structure, as a variation or alternative, the ninth transistor Q9 and the thirteenth transistor Q10 can be replaced by MOSFETs.

[0104] The second set of switching circuits operates as follows: When pin 6 of control module U1A outputs a high level, this high level is provided to transistor Q9 after current limiting by the thirteenth resistor R13, which triggers transistor Q9. Since the collector of transistor Q9 is connected to the output terminal V+ of DC power supply 1 through the sixteenth resistor R16, transistor Q9 conducts after its base is triggered. Since the emitter of transistor Q9 is grounded, its collector is pulled low to a low level after it conducts. The base of transistor Q10 is connected to the collector of transistor Q9, and the emitter of transistor Q10 is connected to the output terminal V+ of DC power supply 1. When the base of transistor Q10 is low, transistor Q10 conducts, and thus the collector of transistor Q10 outputs a high level, i.e., the output terminal of the second set of switching circuits outputs a high level.

[0105] When pin 6 of control module U1A outputs a low level, both transistors Q9 and Q10 are in the off state, meaning the output of the second set of switching circuits is low.

[0106] The first switch group includes a seventh transistor Q7 and an eighth transistor Q8. The base of the seventh transistor Q7 is connected to the output terminal of the control module U1A. The base of the seventh transistor Q7 is connected to pin 7 of the control module U1A through the fourteenth resistor R14. The base of the seventh transistor Q7 is also connected to one end of a twenty-first capacitor C21. The other end of the twenty-first capacitor C21 is grounded. The emitter of the seventh transistor Q7 is grounded. The collector of the seventh transistor Q7 is connected to the base of the eighth transistor Q8 and the output terminal of DC power supply 1. A fifteenth resistor R15 is connected between the seventh transistor Q7 and the output terminal V+ of DC power supply 1. A fifteenth current-limiting resistor R16B is connected between the base of the eighth transistor Q8 and the output terminal V+ of DC power supply 1. The emitter of the eighth transistor Q8 is connected to the output terminal of DC power supply 1. The collector of the eighth transistor Q8 is electrically connected to the first switching switch Q31 and the second switching switch Q32. Based on the above structure, as a variation or alternative, the seventh transistor Q7 and the eighth transistor Q8 can be replaced by MOSFETs.

[0107] The second set of switching circuits operates as follows: When pin 7 of control module U1A outputs a high level, this high level is provided to transistor Q7 after current limiting by resistor R14, which triggers transistor Q7. Since the collector of transistor Q7 is connected to the output terminal V+ of DC power supply 1 through resistor R15, transistor Q7 conducts after its base is triggered. Since the emitter of transistor Q7 is grounded, its collector is pulled low after it conducts. The base of transistor Q8 is connected to the collector of transistor Q7, and the emitter of transistor Q8 is connected to the output terminal V+ of DC power supply 1. When the base of transistor Q8 is low, transistor Q8 conducts, and its collector outputs a high level, which is the output of the first set of switching circuits.

[0108] When pin 7 of control module U1A outputs a low level, both transistors Q7 and Q8 are in the off state, meaning the output of the first set of switching circuits outputs a low level.

[0109] Pins 6 and 7 of the control module U1A alternately output high and low levels. Therefore, the first and second sets of switching circuits alternately output high and low levels.

[0110] The lighting controller also includes a control unit 2. In this embodiment, the structure of the control unit 2 is the same as that in embodiment 1, and will not be described again here.

[0111] Control unit 2 is electrically connected to switching unit 3. Switching unit 3 further includes a first switching switch Q31 and a second switching switch Q32. The first switching switch Q31 is electrically connected to the output terminal of the first switching group and control unit 2 to form a first switching circuit. The second switching switch Q32 is electrically connected to the output terminal of the first switching group and control unit 2 to form a third switching circuit. In this embodiment, both the first switching switch Q31 and the second switching switch Q32 are thyristors. Pin 11 of microcontroller U2 in control unit 2 is connected to the gate of the first switching switch Q31 through the thirteenth current-limiting resistor R13B, and pin 2 of microcontroller U2 is connected to the gate of the second switching switch Q32 through the fourteenth current-limiting resistor R14B.

[0112] The control unit 2 is used to provide trigger signals to the first switch Q31 and the second switch Q32. When the output terminal of the first switch group outputs a high level, the control unit 2 controls the first switch Q31 or the second switch Q32 to be turned on. When the output terminal of the first switch group outputs a low level, the first switch Q31 or the second switch Q32 is turned off.

[0113] In the above structure, the output terminal of the first switching switch Q31 is the load connection part A, the output terminal of the second set of switching circuits is the load connection part B, and the output terminal of the second switching switch Q32 is the load connection part C. Load connection parts A, B, and C are respectively connected to... Figure 4 or Figure 5 The lamp 3a shown is connected to control the light emission of each lamp string. The specific principle of controlling the conduction of each lamp string is the same as in Example 1, and will not be repeated here.

[0114] The switching unit 3 of Embodiment 2 can output a higher voltage, such as a 40V circuit, that is, the output terminals of the first group of switches and the second group of switches can both output 40V. Therefore, a thirty-first current-limiting resistor R31 is connected between the output terminal of the second switching switch Q32 and the output terminal of the second group of switching circuits, and a thirty-second current-limiting resistor R32 is connected between the output terminal of the first switching switch Q31 and the output terminal of the second group of switching circuits. The current is reduced by the current-limiting resistors to avoid damaging the lamp 3a connected later.

[0115] This embodiment also includes a power supply circuit for supplying power to the control unit 2. The output terminal of the first switch group is also connected to the power supply circuit, and the power supply circuit is electrically connected to the control unit 2. That is, this embodiment preferentially does not directly supply power to the control unit 2 from the DC power supply 1, but instead supplies power to the control unit 2 indirectly. In this embodiment, when the output terminal of the first switch group, i.e., the collector of the eighth transistor Q8, outputs a high level, the power supply circuit is charged, and the power supply circuit discharges to supply power to the control unit 2.

[0116] The power supply circuit includes an energy storage element C6B, a rectifier D30, and a thirtieth resistor R30. One end of the energy storage element C6B is electrically connected to the output terminal of the first switch group, that is, one end of the energy storage element C6B is connected to the collector of the eighth transistor Q8 and pin 5 of the microcontroller U2. The other end of the energy storage element C6B is electrically connected to the anode of the rectifier D30. The cathode of the rectifier D30 is connected to one end of the thirtieth resistor R30. The other end of the thirtieth resistor R30 is electrically connected to the first switch group, that is, the other end of the thirtieth resistor R30 is connected to the collector of the seventh transistor Q7.

[0117] For the power supply circuit, the current flow path is as follows: the current is output from the eighth transistor Q8, passes sequentially through the energy storage element C6B, the rectifier D30, the thirtieth resistor R30, the collector of the seventh transistor Q7, the emitter of the seventh transistor Q7, and finally to ground. During this process, the current is reduced by the current limiting effect of the thirtieth resistor R30.

[0118] The power supply circuit also includes a voltage regulator ZD30, which is connected in parallel with the energy storage element C6B. The voltage regulator ZD30 keeps the voltage of the power supply circuit at a stable value.

[0119] It also includes an indicator LED2 that remains constantly lit when powered on to indicate the location of the lighting controller. One end of the indicator LED2 is connected to the energy storage element C6B, and the other end is grounded. Preferably, the indicator LED2 is connected to the energy storage element C6B through a nineteenth resistor R19. The indicator LED2 ensures that the user can promptly locate the lighting controller.

[0120] It also includes a mode selector that inputs a light flashing mode switching signal or a light timing signal to the control unit 2. This mode selector is electrically connected to the control unit. The mode selector is the same as in Embodiment 1, and will not be described again here.

[0121] It also includes a sampling circuit that enables control unit 2 to detect whether the output of the second set of switching circuits is high or low. One end of the sampling circuit is connected to the output of the second set of switching circuits, and the other end is electrically connected to control unit 2. The sampling circuit includes a 33rd resistor R33 and a 33rd capacitor C33. One end of the 33rd resistor R33 is connected to the output of the second set of switching circuits, i.e., connected to the load connection part B. The other end of the 33rd resistor R33 is connected to pin 9 of microcontroller U2 and one end of the 33rd capacitor C33, and the other end of the 33rd capacitor C33 is grounded. The 33rd resistor R33 is used for current limiting to reduce current, and the 33rd capacitor C33 is used for filtering.

[0122] After obtaining the voltage output by the sampling circuit, the microcontroller U2 determines in real time whether the output of the second set of switching circuits is high or low, so as to accurately output the trigger signal to the first switching switch Q31 or the second switching switch Q32.

[0123] like Figure 7 As shown, this embodiment also provides a method for controlling the lighting fixture, including the following steps:

[0124] S1. After power-on, control unit 2 outputs a control signal and receives a switching signal from the mode selector. If the controller has a memory chip U3, before power-off during the last operation, memory chip U3 will record the control signal of the current light-emitting mode output by control unit 2. After the next power-on, control unit 2 reads the control signal of the previously output light-emitting mode from memory chip U3 and outputs it as the control signal of the light-emitting mode after power-on. If the controller does not have a memory chip U3, control unit 2 outputs the light-emitting mode according to the program settings. The mode selector is a push-button switch SW or a touch switch connected to control unit 2. The mode selector can also be a wireless signal transmitter.

[0125] S2, if the control unit 2 determines that the switching signal input by the mode selector is a light flashing mode switching signal, then the control unit 2 outputs a flashing mode switching control signal to the switch unit 3, and the flashing mode switching control signal controls the order of the switch unit 3 to be turned on or off.

[0126] In step S2, the control unit 2 determines that the switching signal input by the mode selector is a light flashing mode switching signal based on the following: the mode selector is pressed once, and the pressing time is less than or equal to the first time set by the control unit 2. For example, the pressing time does not exceed 1 second. Pressing turns the button switch SW or touch switch on or off. Preferably, the button switch SW or touch switch is turned on. Therefore, the pressing time not exceeding 1 second means that the time for pressing once to turn on the button switch SW or touch switch does not exceed 1 second.

[0127] The wireless signal transmitter has multiple selection buttons. After operating each selection button, the wireless signal transmitter can emit a corresponding coded signal. The coded signal corresponding to each button is different. After receiving these coded signals, the control unit 2 compares them with the coded signal to identify the specific mode corresponding to the coded signal, such as the flashing mode or the timing mode of the lamp 3a.

[0128] If a wireless signal transmitter outputs a wireless code signal for switching the flash mode, the control unit 2 receives and identifies the wireless code signal sent by the wireless signal transmitter for switching the flash mode through the wireless signal receiver U4, and then outputs a control signal to change the flash mode of the lamp 3a.

[0129] S3, if the control unit 2 determines that the switching signal input by the mode selector is a light timing signal, then the control unit 2 controls the operation of outputting the timing control signal according to the input of the mode selector. When the timing time ends, the control unit 2 stops outputting the control signal, and at this time, the light fixture is turned off.

[0130] In step S3, the basis for the control unit 2 to determine that the switching signal input by the mode selector is a lighting timing signal is: pressing the mode selector multiple times within the second time period set by the control unit 2; for example, pressing the button switch SW or the touch switch twice in a row within 1 second, that is, the second time is within 1 second. Therefore, within 1 second, the control unit 2 obtains the signal that the mode selector is turned on twice in a row, thereby determining that the user has enabled the lamp to enter the timing working mode through the mode selector.

[0131] In step S3, the basis for the control unit 2 to determine that the switching signal input by the mode selector is the light timing signal can also be: the duration of continuous pressing of the mode selector is greater than or equal to the third time set by the control unit 2. For example, the duration of continuous pressing of the button switch SW is greater than 2 seconds, that is, the third time is greater than 2 seconds.

[0132] After entering the timing mode, if the control unit 2 still receives the light flashing mode switching signal, it will switch the flashing mode in the timing mode according to step S2.

[0133] When the mode selector uses a push-button switch SW or a touch switch, if the control unit 2 receives a switching signal from the mode selector as a light timing signal again after entering the timing mode, the timing will be turned off.

[0134] If the timing mode is selected wirelessly, control unit 2 receives the timing code sent by the wireless signal transmitter via wireless signal receiver U4. For example, after receiving the second code, control unit 2 starts the timing and sets the timing duration, such as turning off lamp 3a after 6 hours. Of course, the wireless signal transmitter can send multiple timing codes; for example, it can send a third timing code, which turns off lamp 3a after 8 hours. Control unit 2 starts the timing after receiving the timing code, and stops the timing after receiving the code signal to cancel the timing.

[0135] when Figure 4 or Figure 5 and Figures 11a to 36f After connecting any of them, or Figures 8 to 10 for Figures 37a to 42f Any of the control units and switching units in the controller can be used to control each lamp using the above method.

[0136] The control method of the present invention is not limited to the above embodiments, for example:

[0137] (a) The basis for the control unit 2 to determine in step S2 that the switching signal input by the mode selector is the light flashing mode switching signal is: pressing the mode selector multiple times within the second time period set by the control unit 2, for example, pressing the button switch SW or the touch switch twice in a row within 1 second.

[0138] (b) In step S2, the basis for the control unit 2 to determine that the switching signal input by the mode selector is the light flashing mode switching signal is: the duration of continuous pressing of the mode selector is greater than or equal to the third time set by the control unit 2, for example, the duration of continuous pressing of the button switch SW is greater than 2 seconds.

[0139] (c) In step S3, the basis for the control unit 2 to determine that the switching signal input by the mode selector is a light timing signal is: pressing the mode selector once, and the pressing time is less than or equal to the first time set by the control unit 2. For example, the time for each press does not exceed 1 second.

[0140] The previous control method was based on the controller's ability to switch between the light flashing mode switching signal and the light timing signal. For some controllers, only the light timing needs to be switched; the light flashing mode is automatically implemented by the program and does not need to be switched. For example, if there are eight flashing modes, after power-on, it can only output and cycle through these eight flashing modes sequentially. For such controllers, this invention also configures the following control method:

[0141] After power-on, the control unit 2 outputs a control signal to make the lamp work. This control signal is the inherent eight cycle flashing modes described above. If the control unit 2 receives a timing switching signal from the mode selector, the control unit 2 switches the operation of the control unit outputting the timing control signal according to the input of the mode selector. When the timing time ends, the control unit 2 stops outputting the control signal.

[0142] The mode selector is a push-button switch SW or a touch switch connected to the control unit 2. The control unit 2 determines whether the mode selector sends a timing switching signal based on the following criteria: pressing the mode selector once for a duration less than or equal to a first time set by the control unit 2 (e.g., within 1 second); or pressing the mode selector multiple times within a second time period set by the control unit 2 (e.g., pressing the push-button switch SW or touch switch twice consecutively within 1 second); or continuously pressing the mode selector for a duration greater than or equal to a third time period set by the control unit 2, with the continuous pressing of the push-button switch SW for a duration greater than 2 seconds.

[0143] Whether in the power-on operating mode or the timed operating mode, the brightness of the light or the control panel can be switched by operating the button switch SW or the touch switch. For example, pressing the mode selector once for a duration less than or equal to a first time set by control unit 2 (e.g., within 1 second); or pressing the mode selector multiple times within a second time set by control unit 2 (e.g., pressing the button switch SW or touch switch twice consecutively within 1 second); or continuously pressing the mode selector for a duration greater than or equal to a third time set by control unit 2 (e.g., pressing the button switch SW for more than 2 seconds). For another example, continuously pressing the mode selector for a duration greater than or equal to the third time set by control unit 2 will turn the controller on or off.

[0144] Both the operation of the timing mode and the operation of switching the light brightness are achieved by operating the same button switch, but the signal sending mode is different. For example, pressing the mode selector once in the first time interval switches the brightness, while pressing the mode selector multiple times in the second time interval set by the control unit 2 switches the timing mode. That is, the operation of timing, dimming and switch controller do not overlap.

[0145] Of course, all of the above operations can also be performed using two push-button switches (SW) or touch switches. One push-button switch (SW) or touch switch is used to switch the light brightness or switch the controller, and the other push-button switch (SW) or touch switch is used to enter or exit the timer.
