[0035] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The track light and its control circuit according to the embodiment of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In some embodiments, the track light includes a first track and a second track that are arranged correspondingly, and a plurality of lamps and a controller that are connected across the first track and the second track, and the plurality of lamps and the controller are electrically connected through the first track and the second track, and each lamp includes a plurality of light-emitting elements with different color temperatures. Figure 1 , a track light including two lamps, one lamp including two light-emitting elements with different color temperatures and a controller is used as an example for explanation, but this is not intended to limit the present invention.

[0038] Specifically, refer to Figure 1-Figure 3 , the lamp 1, the lamp 6 and the controller 2 are connected across the first track 3 and the second track 4. The lamp 1 and the lamp 6 both include a first light-emitting element L1 and a second light-emitting element L2, and the color temperatures of the first light-emitting element L1 and the second light-emitting element L2 are different, for example, the first light-emitting element L1 emits warm light, and the second light-emitting element L2 emits cold light. The controller 2 includes a first switch circuit 22 and a second switch circuit 23 (the switch circuits correspond to the light-emitting elements of the lamps one by one). The power supply 5 (for example, an AC-DC power supply) is also connected across the first track 3 and the second track 4, for example, the positive pole of the AC-DC power supply is connected across the first track 3, and the negative pole of the AC-DC power supply is connected across the second track 4, so that the first track 3 and the second track 4 are energized, and then the lamp 1, the lamp 6 and the controller 2 are electrically connected. The controller 2 can control the lamp 1 and the lamp 6, for example, control the first switch circuit 22 to turn on so that the lamps light up in warm colors, and control the second switch circuit 23 to turn on so that the lamps light up in cold colors.

[0039] It should be noted that the lamp 1, the lamp 6, the controller 2 and the power supply 5 can be arranged at any position of the track, and the specific position is determined according to the actual situation, and no specific limitation is made here. In addition, the positive pole of the power supply 5 is connected across the first track 3, and the negative pole is connected across the second track 4 to permanently fix the position of the spring piece, and the positive and negative poles will not be exchanged.

[0040] In the related art, one or more of the lamps 1, 6 and the controller 2 may be connected to the first track 3 and the second track 4 in a forward connection state or a reverse connection state. Different connection states of the lamps 1 and 6 will result in different color temperatures of the lamps in the same circuit.

[0041] For example, refer to Figure 2 When the lamp 1, the lamp 6 and the controller 2 are all in the positive connection state, the second switch circuit 23 in the controller 2 is in the on state, then the second light-emitting element L2 of the lamp 1 emits light, and the second light-emitting element L2 of the lamp 6 emits light.

[0042] Reference Figure 3 When the lamp 1 and the controller 2 are both in the forward connection state and the lamp 6 is in the reverse connection state, the second switch circuit 23 in the controller 2 is in the on state, then the second light-emitting component L2 of the lamp 1 emits light, and the first light-emitting component L1 of the lamp 6 emits light. At this time, the color temperatures of the lamps in the same circuit are different.

[0043] To solve the above problems, the control circuit of the present invention includes: a first detection circuit 11 and a gating circuit 12 arranged in each lamp, the first detection circuit 11 is used to detect the connection status of the lamp on the first track 3 and the second track 4, the gating circuit 12 is electrically connected to the first detection circuit 11, multiple light-emitting components, the first track 3 and the second track 4, respectively, and is used to control each light-emitting component to be connected to the first track 3 or the second track 4 based on the connection status; and / or, a second detection circuit 21, multiple switch circuits and a processor 24 are arranged in the controller 2, the multiple switch circuits correspond one-to-one to the multiple light-emitting components, and each switch circuit is electrically connected to the first track 3 or the second track 4, the second detection circuit 21 is used to detect the connection status of the controller 2 on the first track 3 and the second track 4, the processor 24 is electrically connected to the second detection circuit 21 and the multiple switch circuits, respectively, and is used to control the multiple switch circuits based on the connection status.

[0044] Specifically, by setting a first detection circuit 11 and a selection circuit 12 in each lamp, the selection circuit 12 controls each light-emitting component to be connected to the first track 3 or the second track 4 based on the connection status, and a second detection circuit 21, multiple switch circuits and a processor 24 are provided in the controller 2. The second detection circuit 21 detects the connection status of the controller 2 on the first track 3 and the second track 4 and outputs a corresponding control signal to the processor 24. The processor 24 controls one of the multiple switch circuits to be turned on, so that the color temperature of the lamps 1 and 6 remains consistent regardless of whether they are in the forward connection state or the reverse connection state.

[0045] For example, refer to Figure 4 , when the second detection circuit 21 detects that the controller 2 is in the positive connection state, the second detection circuit 21 will transmit a signal (for example, a high level) to the processor 24, and the processor 24 turns on the first switch circuit 22 and turns off the second switch circuit 23. At this time, if the first detection circuit 11 detects that the lamp is in the positive connection state, it will transmit the positive connection control signal to the selection circuit 12, and the selection circuit 12 controls the first light-emitting component L1 of the lamp to be connected to the first track 3, and the second light-emitting component L2 of the lamp to be connected to the second track 4 based on the positive connection control signal. At this time, the first light-emitting component L1 of the lamp, the selection circuit 12, the first track 3, and the first switch circuit 22 form a loop, and the first light-emitting component L1 of the lamp emits light.

[0046] For example, refer to Figure 5 , the controller 2 is still in the forward connection state, the first switch circuit 22 is turned on, and the second switch circuit 23 is turned off. If the first detection circuit 11 detects that the lamp is in the reverse connection state, it will transmit the reverse connection control signal to the selection circuit 12. The selection circuit 12 can still control the first light-emitting part L1 of the lamp to be connected to the first track 3, and the second light-emitting part L2 of the lamp to be connected to the second track 4 based on the reverse connection control signal. At this time, the first light-emitting part L1 of the lamp, the selection circuit 12, the first track 3, and the first switch circuit 22 form a loop, and the first light-emitting part L1 of the lamp emits light.

[0047] For example, refer to Figure 6 , when the second detection circuit 21 detects that the controller 2 is in a reverse connection state, the second detection circuit 21 will transmit a signal (for example, a high level) to the processor 24, and the processor 24 turns on the second switch circuit 23 and turns off the first switch circuit 22. If the first detection circuit 11 detects that the lamp is in a forward connection state, it will transmit a forward connection control signal to the selection circuit 12, and the selection circuit 12 controls the first light-emitting component L1 of the lamp to be connected to the first track 3, and the second light-emitting component L2 of the lamp to be connected to the second track 4 based on the forward connection control signal. At this time, the first light-emitting component L1 of the lamp, the selection circuit 12, the first track 3, and the second switch circuit 23 form a loop, and the first light-emitting component L1 of the lamp emits light.

[0048] For example, refer to Figure 7 , the controller 2 is still in the reverse connection state, the second switch circuit 23 is turned on, and the first switch circuit 22 is turned off. If the first detection circuit 11 detects that the lamp is in the reverse connection state, it will transmit the reverse connection control signal to the selection circuit 12. The selection circuit 12 can still control the first light-emitting part L1 of the lamp to be connected to the first track 3, and the second light-emitting part L2 of the lamp to be connected to the second track 4 based on the reverse connection control signal. At this time, the first light-emitting part L1 of the lamp, the selection circuit 12, the first track 3, and the second switch circuit 23 form a loop, and the first light-emitting part L1 of the lamp emits light.

[0049] That is to say, no matter the lamp is in the forward connection state or the reverse connection state, and the controller 2 is in the forward connection state or the reverse connection state, the color of the lamps in the loop is consistent. In this way, the problem of inconsistent color temperature of multiple lamps in one loop is solved.

[0050] In some embodiments, reference Figure 4 The multiple light-emitting components include a first light-emitting component L1 and a second light-emitting component L2. The selection circuit 12 is used to: when the connection state of the lamp is in a forward connection state, control the first light-emitting component L1 to be connected to the first track 3, and control the second light-emitting component L2 to be connected to the second track 4; when the connection state of the lamp is in a reverse connection state, control the first light-emitting component L1 to be connected to the first track 3, and control the second light-emitting component L2 to be connected to the second track 4.

[0051] For example, refer to Figure 4 or Figure 6 When the connection state of the lamp is in the positive connection state, the selection circuit 12 can control the first light-emitting element L1 to be connected to the first track 3, and control the second light-emitting element L2 to be connected to the second track 4. Figure 5 or Figure 7 When the connection state of the lamp is in the reverse connection state, the selection circuit 12 can still control the first light-emitting element L1 to be connected to the first track 3, and control the second light-emitting element L2 to be connected to the second track 4.

[0052] In some embodiments, reference Figure 8 , the gating circuit 12 comprises: a first gating subcircuit 121, a first terminal a1 of the first gating subcircuit 121 being electrically connected to the first light-emitting element L1, a second terminal b1 of the first gating subcircuit 121 being adapted to be electrically connected to the first track 3, a third terminal c1 of the first gating subcircuit 121 being electrically connected to the second light-emitting element L2, and a fourth terminal d1 of the first gating subcircuit 121 being adapted to be electrically connected to the second track 4; wherein, in the positive connection state, the first terminal a1 of the first gating subcircuit 121 is connected to the second terminal b1, and the third terminal c1 is connected to the fourth terminal d1;

[0053] The second enabling subcircuit 122, the first terminal a2 of the second enabling subcircuit 122 is electrically connected to the first light-emitting element L1, the second terminal b2 of the second enabling subcircuit 122 is suitable for electrically connecting to the second track 4, the third terminal c2 of the second enabling subcircuit 122 is electrically connected to the second light-emitting element L2, and the fourth terminal d2 of the second enabling subcircuit 122 is suitable for electrically connecting to the first track 3; wherein, in the reverse connection state, the first terminal a2 of the second enabling subcircuit 122 is connected to the second terminal b2, and the third terminal c2 is connected to the fourth terminal d2.

[0054] Specifically, the gating circuit 12 includes a first gating subcircuit 121 and a second gating subcircuit 122. When the lamp is in a forward connection state, the first light-emitting element L1 can be connected to the first track 3 and the second light-emitting element L2 can be connected to the second track 4 by connecting the first gating subcircuit 121. When the lamp is in a reverse connection state, the first light-emitting element L1 can be connected to the second track 4 and the second light-emitting element L2 can be connected to the first track 3 by connecting the second gating subcircuit 122.

[0055] For example, refer to Figure 8 In the positive connection state of the lamp, the second selection subcircuit 122 is disconnected, and the first selection subcircuit 121 is connected, specifically, the first end a1 and the second end b1 of the first selection subcircuit 121 are connected, and the third end c1 and the fourth end d1 are connected. At this time, the first selection subcircuit 121 can control the first light-emitting element L1 to be connected to the first track 3, and control the second light-emitting element L2 to be connected to the second track 4.

[0056] Exemplarily, in the reverse connection state of the lamp, the first selection subcircuit 121 is disconnected, and the second selection subcircuit 122 is connected, specifically, the first end a2 and the second end b2 of the second selection subcircuit 122 are connected, and the third end c2 and the fourth end d2 are connected. At this time, the second selection subcircuit 122 can control the first light-emitting element L1 to be connected to the second track 4, and control the second light-emitting element L2 to be connected to the first track 3.

[0057] In some embodiments, the first selection subcircuit 121 may include: a first switch tube Q1, a first diode D1, a second switch tube Q2 and a second diode D2, the first end of the first switch tube Q1 is electrically connected to the first light-emitting element L1, the second end of the first switch tube Q1 is electrically connected to the anode of the first diode D1, and the cathode of the first diode D1 is suitable for connecting to the first track 3; the first end of the second switch tube Q2 is electrically connected to the second light-emitting element L2, the second end of the second switch tube Q2 is electrically connected to the anode of the second diode D2, and the cathode of the second diode D2 is suitable for connecting to the second track 4; the control ends of the first switch tube Q1 and the second switch tube Q2 are respectively electrically connected to the first output end of the first detection circuit 11, and the first output end is used to output a positive control signal corresponding to the positive connection state.

[0058] Specifically, when the first detection circuit 11 detects that the lamp is in the positive connection state, it will transmit the positive connection control signal (high level signal) to the control end of the first switch tube Q1 and the second switch tube Q2, so that the first switch tube Q1 and the second switch tube Q2 are turned on, that is, the first selection sub-circuit 121 is turned on.

[0059] For example, refer to Figure 8 In the forward connection state of the lamp, the first light-emitting element L1 is connected to the first track 3 via the first end of the first switch tube Q1, the second end of the first switch tube Q1, the anode of the first diode D1, and the cathode of the first diode D1. The second light-emitting element L2 is connected to the second track 4 via the first end of the second switch tube Q2, the second end of the second switch tube Q2, the anode of the second diode D2, and the cathode of the second diode D2.

[0060] In some embodiments, reference Figure 8 The second selection subcircuit 122 may include: a third switch tube Q3, a third diode D3, a fourth switch tube Q4 and a fourth diode D4, the first end of the third switch tube Q3 is electrically connected to the first light-emitting element L1, the second end of the third switch tube Q3 is electrically connected to the anode of the third diode D3, and the cathode of the third diode D3 is suitable for connecting to the second track 4; the first end of the fourth switch tube Q4 is electrically connected to the second light-emitting element L2, the second end of the fourth switch tube Q4 is electrically connected to the anode of the fourth diode D4, and the cathode of the fourth diode D4 is suitable for connecting to the first track 3; the control ends of the third switch tube Q3 and the fourth switch tube Q4 are respectively electrically connected to the second output end of the first detection circuit 11, and the second output end is used to output a reverse control signal corresponding to the reverse connection state.

[0061] Specifically, when the first detection circuit 11 detects that the lamp is in a reverse connection state, a reverse connection control signal (high level signal) is transmitted to the control ends of the third switch tube Q3 and the fourth switch tube Q4, so that the third switch tube Q3 and the fourth switch tube Q4 are turned on, that is, the second selection subcircuit 122 is turned on.

[0062] For example, refer to Figure 8 In the reverse connection state of the lamp, the first light-emitting element L1 is connected to the second track 4 via the first end of the third switch tube Q3, the second end of the third switch tube Q3, the anode of the third diode D3, and the cathode of the third diode D3. The second light-emitting element L2 is connected to the first track 3 via the first end of the fourth switch tube Q4, the second end of the fourth switch tube Q4, the anode of the fourth diode D4, and the cathode of the fourth diode D4.

[0063] In some embodiments, the positive and negative poles of multiple lamps are electrically connected to the first track 3 and the second track 4 to obtain power through the first track 3 and the second track 4, and the first detection circuit 11 is used to detect the positive and negative pole connection status of the lamp as the connection status of the lamp.

[0064] Specifically, the first detection circuit 11 can determine the connection state of the lamp by detecting the connection state of the positive and negative poles of the lamp. For example, if the positive pole of the lamp is electrically connected to the first track 3 and the negative pole of the lamp is electrically connected to the second track 4, it is determined that the lamp is in a positive connection state; if the positive pole of the lamp is electrically connected to the second track 4 and the negative pole of the lamp is electrically connected to the first track 3, it is determined that the lamp is in a reverse connection state.

[0065] In some embodiments, reference Figure 8 The first detection circuit 11 includes: a first detection subcircuit 111, which is electrically connected to the positive and negative poles of the lamp and the selection circuit 12 respectively, and is used to output a positive control signal when the positive and negative pole connection states are detected to be in a positive state; a second detection subcircuit 112, which is electrically connected to the positive and negative poles of the lamp and the selection circuit 12 respectively, and is used to output a reverse control signal when the positive and negative pole connection states are detected to be in a reverse state.

[0066] For example, refer to Figure 8 When the first detection subcircuit 111 detects that the lamp is in the forward connection state, it will output a forward connection control signal (high level signal) to the first selection subcircuit 121, so that the first selection subcircuit 121 is turned on. When the second detection subcircuit 112 detects that the lamp is in the reverse connection state, it will output a reverse connection control signal (high level signal) to the second selection subcircuit 122, so that the second selection subcircuit 122 is turned on.

[0067] In some embodiments, reference Figure 8 The first detection subcircuit 111 includes: a first resistor R1, one end of the first resistor R1 is electrically connected to the positive electrode of the lamp; a fifth diode D5, an anode of the fifth diode D5 is electrically connected to the other end of the first resistor R1, and the connection point serves as the first output end of the first detection circuit 11 to output a positive control signal; a second resistor R2, one end of the second resistor R2 is electrically connected to the cathode of the fifth diode D5, and the other end of the second resistor R2 is electrically connected to the negative electrode of the lamp.

[0068] Specifically, refer to Figure 8 If the positive pole of the lamp is electrically connected to the first track 3 and the negative pole of the lamp is electrically connected to the second track 4, the positive control signal (high level signal) will be obtained through the voltage division of the first resistor R1, the second resistor R2 and the fifth diode D5 in the first detection sub-circuit 111, and transmitted to the control ends of the first switch tube Q1 and the second switch tube Q2, so that the first switch tube Q1 and the second switch tube Q2 are turned on.

[0070] Specifically, refer to Figure 8 If the positive pole of the lamp is electrically connected to the second track 4, and the negative pole of the lamp is electrically connected to the first track 3, the voltage will be divided by the third resistor R3, the fourth resistor R4 and the sixth diode D6 in the second detection sub-circuit 112 to obtain a reverse control signal (high level signal), and transmitted to the control ends of the third switch tube Q3 and the fourth switch tube Q4, so that the third switch tube Q3 and the fourth switch tube Q4 are turned on.

[0071] In some embodiments, the plurality of light-emitting elements include a first light-emitting element L1 and a second light-emitting element L2, the plurality of switch circuits include a first switch circuit 22 and a second switch circuit 23, and the processor 24 is used to: when the connection state of the controller 2 is in a forward connection state, control the first switch circuit 22 to close so that the first light-emitting element L1 emits light, or control the second switch circuit 23 to close so that the second light-emitting element L2 emits light; when the connection state of the controller 2 is in a reverse connection state, control the second switch circuit 23 to close so that the first light-emitting element L1 emits light, or control the first switch circuit 22 to close so that the second light-emitting element L2 emits light.

[0072] Specifically, refer to Figure 8 and Fig. 9 , the first end Ua of the processor 24 is connected to the first switch circuit 22, and the second end Ub of the processor 24 is connected to the second switch circuit 23, for controlling the closing or opening of the first switch circuit 22 or the second switch circuit 23. When the connection state of the controller 2 is in the positive connection state, the first switch circuit 22 is connected to the first track 3, and the second switch circuit 23 is connected to the second track 4. On the contrary, referring to Fig.10 , when the connection state of the controller 2 is in the reverse connection state, the first switch circuit 22 is connected to the second track 4, and the second switch circuit 23 is connected to the first track 3. It can be seen from the above embodiment that no matter whether the lamp is in the forward connection state or the reverse connection state, the first light-emitting element L1 is connected to the first track 3, and the second light-emitting element L2 is connected to the second track 4.

[0073] Therefore, when the connection state of the controller 2 is in the forward connection state, if the processor 24 controls the first switch circuit 22 to be closed, the first light-emitting element L1 can be illuminated, and if the processor 24 controls the second switch circuit 23 to be closed, the second light-emitting element L2 can be illuminated. When the connection state of the controller 2 is in the reverse connection state, if the processor 24 controls the first switch circuit 22 to be closed, the second light-emitting element L2 can be illuminated, and if the second switch circuit 23 is controlled to be closed, the first light-emitting element L1 can be illuminated.

[0074] In some embodiments, the first switch circuit 22 includes: a fifth switch tube Q5, the first end of the fifth switch tube Q5 is suitable for connecting to the first rail 3 or the second rail 4, the second end of the fifth switch tube Q5 is grounded, and the control end of the fifth switch tube Q5 is electrically connected to the first end Ua of the processor 24.

[0075] Specifically, refer to Fig. 9 The control end of the fifth switch tube Q5 is electrically connected to the first end Ua of the processor 24. If the first end Ua of the processor 24 outputs a high level signal, the fifth switch tube Q5 can be controlled to be turned on, that is, the first switch circuit 22 is closed. If the first end Ua of the processor 24 outputs a low level signal, the fifth switch tube Q5 can be controlled to be turned off, that is, the first switch circuit 22 is turned off.

[0076] For example, refer to Fig. 9 , when the connection state of the controller 2 is in the positive connection state, if the fifth switch tube Q5 is turned on (the first switch circuit 22 is closed), the voltage forms a loop through the first light-emitting element L1, the first selection subcircuit 121, the first track 3, the first end of the fifth switch tube Q5, and the second end of the fifth switch tube Q5 is grounded, so that the first light-emitting element L1 can emit light. On the contrary, if the fifth switch tube Q5 is disconnected (the first switch circuit 22 is disconnected), the loop cannot be formed, and the first light-emitting element L1 does not emit light.

[0077] For example, refer to Fig.10 , when the connection state of the controller 2 is in the reverse connection state, if the fifth switch tube Q5 is turned on (the first switch circuit 22 is closed), the voltage forms a loop through the second light-emitting element L2, the first selection subcircuit 121, the second track 4, the first end of the fifth switch tube Q5, and the second end of the fifth switch tube Q5 is grounded, so that the second light-emitting element L2 can emit light. On the contrary, if the fifth switch tube Q5 is disconnected (the first switch circuit 22 is disconnected), the loop cannot be formed, and the second light-emitting element L2 does not emit light.

[0078] In some embodiments, the second switch circuit 23 includes: a sixth switch tube Q6, the first end of the sixth switch tube Q6 is suitable for connecting to the first rail 3 or the second rail 4, the second end of the sixth switch tube Q6 is grounded, and the control end of the sixth switch tube Q6 is electrically connected to the second end Ub of the processor 24.

[0079] Specifically, refer to Fig. 9 The control end of the sixth switch tube Q6 is electrically connected to the second end b of the processor 24. If the second end Ub of the processor 24 outputs a high-level signal, the sixth switch tube Q6 can be controlled to be turned on, that is, the second switch circuit 23 is closed. If the second end Ub of the processor 24 outputs a low-level signal, the sixth switch tube Q6 can be controlled to be turned off, that is, the second switch circuit 23 is turned off.

[0080] For example, refer to Fig. 9 , when the connection state of the controller 2 is in the positive connection state, if the sixth switch tube Q6 is turned on (the second switch circuit 23 is closed), the voltage forms a loop through the second light-emitting element L2, the first selection subcircuit 121, the second track 4, the first end of the sixth switch tube Q6, and the second end of the sixth switch tube Q6 is grounded, so that the second light-emitting element L2 can emit light. On the contrary, if the sixth switch tube Q6 is disconnected (the second switch circuit 23 is disconnected), the loop cannot be formed, and the second light-emitting element L2 does not emit light.

[0081] For example, refer to Fig.10 , when the connection state of the controller 2 is in the reverse connection state, if the sixth switch tube Q6 is turned on (the second switch circuit 23 is closed), the voltage forms a loop through the first light-emitting element L1, the first selection subcircuit 121, the first track 3, the first end of the sixth switch tube Q6, and the second end of the sixth switch tube Q6 is grounded, so that the first light-emitting element L1 can emit light. On the contrary, if the sixth switch tube Q6 is disconnected (the second switch circuit 23 is disconnected), the loop cannot be formed, and the first light-emitting element L1 does not emit light.

[0082] In some embodiments, the positive and negative poles of the controller 2 are electrically connected to the first rail 3 and the second rail 4 to obtain power through the first rail 3 and the second rail 4, and the second detection circuit 21 is used to detect the positive and negative pole connection status of the controller 2 as the connection status of the controller 2.

[0083] Specifically, the second detection circuit 21 can determine the connection state of the controller 2 by detecting the connection state of the positive and negative electrodes of the controller 2. For example, if the positive electrode of the controller 2 is electrically connected to the first track 3 and the negative electrode of the controller 2 is electrically connected to the second track 4, it is determined that the controller 2 is in a positive connection state; if the positive electrode of the controller 2 is electrically connected to the second track 4 and the negative electrode of the controller 2 is electrically connected to the first track 3, it is determined that the controller 2 is in a reverse connection state.

[0084] In some embodiments, the second detection circuit 21 may include: a fifth resistor R5, one end of which is electrically connected to the positive electrode of the controller 2; a seventh diode D7, an anode of which is electrically connected to the other end of the fifth resistor R5; a sixth resistor R6, one end of which is electrically connected to the cathode of the seventh diode D7, and the connection point serves as the output end of the second detection circuit 21 to output a detection signal corresponding to the connection status of the controller 2, and the other end of the sixth resistor R6 is grounded.

[0085] Specifically, when the second detection circuit 21 detects that the controller 2 is in the forward connection state, it will output a high level signal to the processor 24, and the processor 24 will output a high level signal from the first end Ua or the second end Ub, and the corresponding other end will output a low level signal. When the second detection circuit 21 detects that the controller 2 is in the reverse connection state, it will output a low level signal to the processor 24, and the processor 24 will output a high level signal from the first end Ua or the second end Ub, and the corresponding other end will output a low level signal.

[0086] In the embodiment of the present invention, when the second detection circuit 21 detects that the controller 2 is in the forward connection state, the processor 24 outputs a high level signal from the first terminal Ua and outputs a low level signal from the second terminal Ub as an example for explanation, but it is not intended to limit the present invention. Correspondingly, when the second detection circuit 21 detects that the controller 2 is in the reverse connection state, the processor 24 outputs a high level signal from the second terminal Ub and outputs a low level signal from the first terminal Ua.

[0087] In some embodiments, the second detection circuit 21 further includes: a first capacitor, the first capacitor is connected in parallel with the sixth resistor R6; a Zener diode ZD, the cathode of the Zener diode ZD is electrically connected to one end of the sixth resistor R6, and the anode of the Zener diode ZD is electrically connected to the other end of the sixth resistor R6.

[0088] For example, refer to Fig. 9 If the controller 2 is in the forward connection state, the second detection circuit 21 composed of the fifth resistor R5, the seventh diode D7, the sixth resistor R6, the first capacitor and the voltage regulator ZD will output the controller 2 forward connection detection signal (a high-level signal) to the processor 24, and the first end Ua of the processor 24 will output a high-level signal to turn on the fifth switch tube Q5 (that is, the first switch circuit 22 is closed). On the contrary, the second end Ub of the processor 24 will output a low-level signal to turn off the sixth switch tube Q6 (that is, the second switch circuit 23 is disconnected).

[0089] For example, refer to Fig.10If the controller 2 is in the reverse connection state, the second detection circuit 21 composed of the fifth resistor R5, the seventh diode D7, the sixth resistor R6, the first capacitor and the voltage regulator ZD will output the controller 2 reverse connection detection signal (a low level signal) to the processor 24, and the first end Ua of the processor 24 will output a low level signal to disconnect the fifth switch tube Q5 (that is, the first switch circuit 22 is disconnected). On the contrary, the second end Ub of the processor 24 will output a high level signal to turn on the sixth switch tube Q6 (that is, the second switch circuit 23 is closed).

[0090] In addition, the processor is also provided with a radio frequency receiving point (not shown) for receiving the temperature control signal sent by the mobile phone APP, so that the mobile phone APP is consistent with the actual color temperature of the lamp.
