Description

Technical Field

[0001] The utility model relates to the technical field of circuits, and in particular to an intelligent magnetic lamp and a reset circuit thereof, and a combined track lamp. Background Art

[0002] Smart magnetic lamps are free to choose light sources, increase or decrease the number of lamps, move positions, and adjust the irradiation angles. They are more flexible to install and more convenient to disassemble. They can also realize intelligent control of lamps, and can easily control the lights through mobile phone APP or smart speakers to create an ideal home atmosphere. However, smart magnetic lamps need to be reset (cleared) in the later scene changes. The main way to clear the net on the market is to trigger the smart magnetic lamps to perform the clearing operation by the number of switches. When this method is used to clear the net for smart magnetic lamps on the entire magnetic guide rail, it is very easy to forget the number of switches during the operation. There may also be problems that several lamps have not been cleared successfully and need to be repeated. Or if you only want to clear a part of the lamps or a single lamp, you need to remove other lamps, leave the lamps that need to be cleared on the magnetic guide rail, and clear the net by turning on and off the switch panel, or remove the lamps that need to be cleared separately, and then clear the net by turning on and off the power after the matching rail, switch power, and switch panel are connected. Therefore, the current method of clearing the net is rather cumbersome, and it is not possible to quickly and easily clear the nets of some lamps or individual lamps in the magnetic guide rail. This method is also not conducive to the debugging of the lamps and the subsequent scene upgrade and adjustment, which brings certain difficulties and inconveniences to the use and maintenance of smart lamps.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As used in the utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0043] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0044] See also Figure 1As shown in the figure, the embodiment of the present application discloses a reset circuit of an intelligent magnetic lamp, wherein the reset circuit includes a second diode D2, a bridge rectifier circuit BD1, a first diode D1, a first capacitor EC1, a control chip U1 and a constant current control circuit; the first pin and the second pin of the bridge rectifier circuit BD1 are respectively connected to the two ends of a DC power supply, the second pin of the bridge rectifier circuit BD1 is connected to the positive electrode of the second diode D2, and the negative electrode of the second diode D2 is connected to the first pin of the control chip U1; the third pin of the bridge rectifier circuit BD1 and the third pin of the control chip U1 Grounded; the fourth pin of the bridge rectifier circuit BD1 is connected to the positive electrode of the first diode D1, the fifth pin of the control chip U1 and the power supply end of the constant current control circuit; the cathode of the first diode D1 is connected to the second pin of the control chip U1 and one end of the first capacitor EC1, and the other end of the first capacitor EC1 is grounded; the fourth pin of the control chip U1 is connected to the network clearing control port of the wireless module in the constant current control circuit as a network clearing control port, and the constant current output end of the constant current control circuit and the fourth pin of the bridge rectifier circuit BD1 are used to connect the light source component in series.

[0045] Among them, the bridge rectifier circuit BD1 is also the anti-reverse bridge stack in the reset circuit, which is used to realize the unidirectional output of current. The wireless module U2 in the constant current control circuit can receive the wireless control signal sent by the external device (such as remote control, mobile phone, tablet computer, smart speaker, etc.) to control the lamp, and the specific lamp parameters can be recorded during the control of the lamp; the wireless module U2 can also receive the reset signal from the control chip U1 to enter the reset (clear network) state. The DC constant current circuit U3 in the constant current control circuit receives the PWM signal output from the third pin of the wireless module U2, and the third pin of the DC constant current circuit U3 outputs a constant current to drive the light source component. The control chip U1 detects the voltage of the first pin of the control chip U1 to determine whether the current magnetic lamp is installed in the reverse direction. If the control chip U1 determines that the current magnetic lamp is installed in the reverse direction, it outputs a high level through its fourth pin to drive the wireless module U2 to enter the reset (clear network) state. The second pin of the control chip U1 is used to provide VCC power to the control chip U1. The second pin is connected to one end of the first capacitor EC1. The first capacitor EC1 can be an electrolytic capacitor. The first capacitor EC1 is used to store a certain amount of electricity and to briefly power the control chip U1 when the magnetic lamp is powered off, so as to ensure that the control chip U1 can work in a relatively short time. The first diode D1 conducts the electric energy output by the bridge rectifier circuit BD1 in a unidirectional manner and provides it to the control chip U1 and the first capacitor EC1. The first diode D1 can effectively prevent the electric energy in the first capacitor EC1 from being reversely discharged when the magnetic lamp is powered off, that is, to prevent the electric energy in the first capacitor EC1 from being quickly consumed after the magnetic lamp is powered off, thereby extending the duration of powering the control chip U1 through the first capacitor EC1. The second diode D2 is used to conduct the current flowing through it in a unidirectional manner and output it to the first pin of the control chip U1, so that the control chip U1 can detect whether the DC power supply is reversely connected (whether the magnetic lamp is installed in reverse) through the first pin.

[0046] Based on the above-mentioned intelligent magnetic lamp reset circuit, a new reset (net clearing) method is realized. The reset (net clearing) operation can be quickly realized by simply detecting whether the magnetic lamp is installed in the reverse direction through the control chip U1. That is, during the application process of the magnetic lamp based on the intelligent magnetic lamp reset circuit, the lamp can automatically enter the net clearing state by simply turning the installation direction of the magnetic lamp; the above-mentioned reset circuit detects whether the voltage polarity at both ends of the magnetic lamp changes by detecting the level of the first pin of the control chip U1, and compares the polarity of the magnetic lamp after the power is turned on with the previous power polarity through the control chip U1. If the polarity is consistent, it will not enter the net clearing state, and if the polarity is opposite, it will enter the net clearing state. The control chip U1 outputs a reset signal to the constant current control circuit, so that the constant current control circuit enters the reset (net clearing) state and resets the lamp parameters.

[0047] In a more specific embodiment, the reset circuit further includes a first resistor R1; one end of the first resistor R1 is connected to the anode of the second diode D2, and the other end of the first resistor R1 is connected to the second pin of the bridge rectifier circuit BD1. The first capacitor EC1 is an electrolytic capacitor; the anode of the electrolytic capacitor is connected to the second pin of the control chip U1.

[0048] Furthermore, a first resistor R1 and a second diode D2 may be connected in series, and the first resistor R1 is used to limit the current flowing into the first pin of the control chip U1, so as to improve the safety and reliability of the control chip U1 detecting the level of the first pin. In order to improve the reliability of power supply to the second pin of the control chip U1, the first capacitor EC1 may be set as an electrolytic capacitor, and the two ends of the electrolytic capacitor have polarity. The positive electrode of the electrolytic capacitor may be connected to the second pin of the control chip U1, so as to realize reliable power supply to the control chip U1.

[0049] In a more specific embodiment, the bridge rectifier circuit BD1 includes a third diode D3, a fourth diode D4, a fifth diode D5 and a sixth diode D6; the anode of the third diode D3 is connected to the cathode of the fifth diode D5, and the connection point serves as the second pin of the bridge rectifier circuit BD1; the anode of the fourth diode D4 is connected to the cathode of the sixth diode D6, and the connection point serves as the first pin of the bridge rectifier circuit BD1; the cathode of the third diode D3 is connected to the cathode of the fourth diode D4, and the connection point serves as the fourth pin of the bridge rectifier circuit; the anode of the fifth diode D5 is connected to the anode of the sixth diode D6, and the connection point serves as the third pin of the bridge rectifier circuit.

[0050] Specifically, the bridge rectifier circuit BD1 can be configured to consist of four diodes, and the specific connection structure is as follows: Figure 1As shown. Regardless of whether the second pin of the bridge rectifier circuit BD1 is connected to the positive or negative pole of the DC power supply, the fourth pin of the bridge rectifier circuit BD1 can output current and supply power to the control chip U1 and the constant current control circuit. Specifically, if the second pin of the bridge rectifier circuit BD1 is connected to the positive pole of the DC power supply, the first pin of the bridge rectifier circuit BD1 is connected to the negative pole of the DC power supply. Due to the unidirectional conduction of the fourth diode D4, the first pin of the bridge rectifier circuit BD1 cannot output current to the fourth pin of the bridge rectifier circuit BD1; while the second pin of the bridge rectifier circuit BD1 can output current to the fourth pin of the bridge rectifier circuit BD1 through the third diode D3 to ensure that the control chip U1 and the constant current control circuit can be powered. If the second pin of the bridge rectifier circuit BD1 is connected to the negative pole of the DC power supply, the first pin of the bridge rectifier circuit BD1 is connected to the positive pole of the DC power supply. At this time, the second pin of the bridge rectifier circuit BD1 cannot output current to the fourth pin of the bridge rectifier circuit BD1; while the first pin of the bridge rectifier circuit BD1 can output current to the fourth pin of the bridge rectifier circuit BD1 through the fourth diode D4, which can also ensure that the control chip U1 and the constant current control circuit can be powered.

[0051] In a more specific embodiment, the constant current control circuit includes a wireless module U2 and a DC constant current circuit U3; the power supply end of the constant current control circuit includes a first pin of the wireless module U2 and a second pin of the DC constant current circuit U3; the second pin of the wireless module U2 is connected to the control chip U1 as a network clearing control port; the third pin of the wireless module U2 is connected to the first pin of the DC constant current circuit U3; the fourth pin of the wireless module U2 and the fourth pin of the DC constant current circuit U3 are both grounded; the third pin of the DC constant current circuit U3 serves as the constant current output end of the constant current control circuit.

[0052] Specifically, the constant current control circuit can be configured to be composed of a wireless module U2 and a DC constant current circuit U3, wherein the electrical connection structure of the wireless module U2 and the DC constant current circuit U3 is as follows: Figure 1As shown. The wireless module U2 can communicate with the external device through wireless communication, and the external device can send a wireless signal to the wireless module U2 to control the wireless module U2 to configure and store the lamp parameters. The wireless module U2 drives the DC constant current circuit U3 to output a constant current to drive the light source component according to the configured and stored lamp parameters. The first pin of the wireless module U2 and the second pin of the DC constant current circuit U3 are both connected to the fourth pin of the bridge rectifier circuit BD1 to obtain power supply. The second pin of the wireless module U2 is used to receive the level signal output from the control chip U1. If the fifth pin of the control chip U1 outputs a low level to the second pin of the wireless module U2, the wireless module U2 is not triggered to enter the network clearing state; if the fifth pin of the control chip U1 outputs a high level to the second pin of the wireless module U2, the wireless module U2 is triggered to enter the network clearing state. The third pin of the wireless module U2 outputs a PWM signal to the DC constant current circuit U3. The third pin of the DC constant current circuit U3 is connected to the negative pole of the light source assembly. The DC constant current circuit U3 outputs a constant current from the third pin to drive the light source assembly according to the received PWM signal.

[0053] An embodiment of the present application also discloses an intelligent magnetic lamp, wherein the intelligent magnetic lamp includes the intelligent magnetic lamp reset circuit and light source assembly as described in the first aspect above; the positive pole of the light source assembly is connected to the fourth pin of the bridge rectifier circuit BD1, and the negative pole of the light source assembly is connected to the constant current output end of the constant current control circuit.

[0054] The technical method of the present application also discloses a smart magnetic lamp. Each smart magnetic lamp is equipped with the above-mentioned smart magnetic lamp reset circuit, and a light source component is connected to the smart magnetic lamp reset circuit. The electrical connection method of the light source component is as follows: Figure 1 shown.

[0055] In a more specific embodiment, the light source assembly includes at least one light emitting device LED0; the light emitting devices LED0 are connected in series and / or in parallel. Figure 1 As shown, in a specific embodiment of the present application, a light-emitting device LED0 is set as the light source component in the intelligent magnetic lamp, and the light-emitting device LED0 can be equivalent to a light-emitting diode D3. In other embodiments, if multiple light-emitting devices LED0 are connected in series, the cathode of the previous light-emitting device LED0 is connected to the anode of the next light-emitting device LED0, the anode of the frontmost light-emitting device LED0 is used as the anode of the light source component, and the cathode of the last light-emitting device LED0 is used as the cathode of the light source component. If multiple light-emitting devices LED0 are connected in parallel, the anode of each light-emitting device LED0 is connected and used as the anode of the light source component, and the cathode of each light-emitting device LED0 is also connected and used as the cathode of the light source component.

[0056] The present application also discloses a combined track lamp, wherein the combined track lamp includes the intelligent magnetic lamp as described in the above embodiment, as well as a magnetic track 10 and a track card power supply 20. The specific structure of the magnetic track 10 and the track card power supply 20 is as follows: Figures 2 to 4 As shown, a magnetic groove 11 is provided above the magnetic track 10, and the smart magnetic lamp is magnetically snapped into the magnetic groove 11 by magnetic attraction, and the smart magnetic lamp can slide in the magnetic groove 11 along the long axis direction of the magnetic groove 11; two parallel guide rail conductive copper strips 13 are provided in the concave cavity 12 below the magnetic track 10, and the track card power supply 20 is snapped into the concave cavity 12 below the magnetic track 10, and the positive contact 21 and the negative contact 22 of the track card power supply 20 are respectively electrically connected to one of the guide rail conductive copper strips 13; the two guide rail conductive copper strips 13 are respectively electrically connected to the two side enclosures 101 of the magnetic groove 11. The end of the track card power supply 20 is electrically connected to the 220V input line 23.

[0057] Furthermore, the technical method of the present application also discloses a combined track lamp based on the above-mentioned smart magnetic lamp. In addition to the above-mentioned smart magnetic lamp, the combined track lamp also includes a magnetic track 10 and a track card power supply 20. Among them, each smart magnetic lamp is magnetically snapped into the magnetic groove 11 by magnetic attraction, and the magnetic lamp can slide along the long axis direction of the magnetic groove 11. Two parallel guide rail conductive copper strips 13 are provided in the lower concave cavity 12 of the magnetic track 10, and the track card power supply 20 is snapped into the lower concave cavity 12, and the positive contact 21 of the track card power supply 20 is connected to one guide rail conductive copper strip 13, and the negative contact 22 of the track card power supply 20 is connected to the other guide rail conductive copper strip 13. The two guide rail conductive copper bars 13 are electrically connected to the two side enclosures 101 of the magnetic groove 11 respectively. After the smart magnetic lamp is engaged with the magnetic groove 11, the two electrical connection points of the smart magnetic lamp are respectively connected to the two side enclosures 101 of the magnetic groove 11, thereby connecting the smart magnetic lamp to the DC power supply corresponding to the positive contact 21 and the negative contact 22 of the track card power supply 20.

[0058] The present application also discloses a method for resetting an intelligent magnetic lamp. The method is applied to Figure 1 The smart magnetic lamp shown in FIG. Figure 5 As shown, the reset method includes steps S110 to S170.

[0059] S110. When the intelligent magnetic lamp is mounted on the magnetic track, the control chip detects whether the fifth pin thereof is at a high level.

[0060] S120: If the fifth pin of the control chip is at a high level, the fourth pin of the control chip outputs a low level to control the constant current control circuit to output current to light up the light source assembly.

[0061] S130, the control chip detects the level state of its first pin and stores it.

[0062] S140. When the smart magnetic lamp is removed and installed on the magnetic track again, the control chip detects whether the fifth pin thereof changes from a high level to a low level and then recovers to a high level again, thereby obtaining a first detection result.

[0063] S150: If the first detection result is yes, the control chip detects whether the level state of its first pin is the same as the level state stored last time.

[0064] S160: If the level states of the first pin stored twice are the same, the fourth pin of the control chip outputs a low level again.

[0065] S170: If the level states of the first pin stored twice are different, the fourth pin of the control chip outputs a high level to control the constant current control circuit to reset the lamp parameters.

[0066] The above-mentioned smart magnetic lamp reset method can be used to reset (clear the network) a single smart magnetic lamp. The specific implementation principle is: when the smart magnetic lamp is connected to the magnetic guide rail, the first and second pins of the bridge rectifier circuit are connected to the power supply (regardless of positive and negative directions) as the DC input terminal (DC input terminal). After passing through the bridge rectifier circuit, the fourth pin outputs the positive pole and the third pin outputs the negative pole. The positive voltage is supplied to the wireless module and the DC constant current circuit in the constant current control circuit, and then the control chip is powered through the first diode. At this time, the third pin of the wireless module outputs a signal to the first pin of the DC constant current circuit (that is, the dimming control pin). The DC constant current circuit outputs a corresponding current to the light source component (light-emitting device) according to the signal input from the first pin, so that the smart magnetic lamp is lit. At the same time, the control chip also enters the working state, and outputs a low voltage at its fourth pin to keep the second pin of the wireless module at a low level (not entering the network clearing state). At the same time, the level states of the first and fifth pins of the control chip are detected (high level or low level), and the level state of the first pin of the control chip is stored inside the control chip (high level is stored as 1, low level is stored as 0); this time the lamp enters the normal working state. If it is necessary to clear the network for a single lamp, the lamp can be removed from the magnetic guide rail and then installed in the magnetic guide rail in the opposite direction (magnetic lamps are fast Installation and disassembly), which is equivalent to reversing the positive and negative poles of the voltage at the DC input terminal (DC input terminal). Since the magnetic lamp is very easy to install and disassemble, removing the magnetic lamp is equivalent to disconnecting the voltage at the DC input terminal (DC input terminal). Since the electric energy in the first capacitor can still keep the control chip working for a short time, the control chip has maintained normal operation at this time. After power failure, the voltage of the fifth pin of the control chip quickly drops to 0. At this time, the control chip enters the waiting mode, and does not detect the level state of the first pin of the control chip, but only detects the level state of the fifth pin of the control chip.

[0067] After reconnecting to the magnetic guide rail, the DC input end is connected to the power supply, and after passing through the bridge rectifier circuit, the fourth pin outputs the positive pole and the third pin outputs the negative pole. The positive voltage is supplied to the wireless module and the DC constant current circuit in the constant current control circuit, and then the control chip is powered through the first diode. At this time, the fifth pin of the control chip determines whether its level has returned to a high level (if the electrical connection is not loose and the electrical connection is stable, the first detection result must be yes). At this time, the control chip enters the working state again, and the control chip detects the level state of its first pin again (high level is 1, low level is 0). The control chip compares the level state of the first pin stored internally with the current level state, that is, compares whether the level states of the first pin stored twice are the same. If the level states stored twice are the same, the control chip outputs a low level through the fourth pin, and the wireless module in the constant current control circuit does not enter the network clearing mode at this time; if the level states stored twice are not the same, the control chip outputs a high level (reset signal) through the fourth pin, so that the wireless module receiving the reset signal enters the reset (network clearing) mode, that is, resets the lamp parameters of the magnetic lamp. In the above operation process, the polarity of the DC output terminal of the smart magnetic lamp is reversed by reversely connecting the smart magnetic lamp, thereby triggering a single smart magnetic lamp to perform a reset (network clearing) operation.

[0068] The present application also discloses a method for resetting an intelligent magnetic lamp. The method is applied to Figure 1 In the smart magnetic lamp shown, the smart magnetic lamp is mounted on a magnetic track, and two parallel conductive copper bars are arranged in the lower cavity of the magnetic track. The lower side of the magnetic track is provided with a lower cavity for mounting a track card power supply. Figure 6 As shown, the reset method includes steps S210 to S270.

[0069] S210, when the track card type power supply is assembled in the concave cavity below the magnetic track, and the positive contact and the negative contact of the track card type power supply are electrically connected to one of the conductive copper bars of the guide rail respectively, the control chip detects whether its fifth pin is at a high level.

[0070] S220: If the fifth pin of the control chip is at a high level, the fourth pin of the control chip outputs a low level to control the constant current control circuit to output current to light up the light source assembly.

[0071] S230: The control chip detects the level state of the first pin and stores it.

[0072] S240, when the track card power supply is removed and installed again in the concave cavity below the magnetic track, the control chip detects whether its fifth pin changes from a high level to a low level and then returns to a high level again, to obtain a first detection result.

[0073] S250: If the first detection result is yes, the control chip detects whether the level state of its first pin is the same as the level state stored last time.

[0074] S260: If the level states of the first pin stored twice are the same, the fourth pin of the control chip outputs a low level again.

[0075] S270: If the level states of the first pin stored twice are different, the fourth pin of the control chip outputs a high level to control the constant current control circuit to reset the lamp parameters.

[0076] The above-mentioned smart magnetic lamp reset method can be used to perform batch reset (net clearing) operations on multiple smart magnetic lamps connected to the magnetic track. This method can improve the net clearing operation efficiency of smart magnetic lamps. The specific implementation principle is similar to the above-mentioned principle of net clearing operation on a single smart magnetic lamp. Here, the polarity of the DC input terminal of each smart magnetic lamp connected to the magnetic track is reversed by reverse insertion of the track card power supply, thereby triggering each smart magnetic lamp to perform a reset (net clearing) operation. Figure 3 Corresponding to the first direction of the track card power supply being inserted into the concave cavity below the magnetic track, Figure 4 Corresponding to the second direction of inserting the track card power supply into the concave cavity below the magnetic track, by changing the insertion direction of the track card power supply, the purpose of controlling the reverse polarity of the DC input terminal of the smart magnetic lamp through the reverse insertion of the track card power supply is achieved.

The first and second pins of the bridge rectifier circuit are respectively connected to the two ends of the DC power supply; the fourth pin of the bridge rectifier circuit is connected to the positive electrode of the first diode, the fifth pin of the control chip, and the power supply end of the constant current control circuit; the negative electrode of the first diode is connected to the second pin of the control chip and one end of the first capacitor; the fourth pin of the control chip is connected to the network clearing control port of the constant current control circuit. The reset circuit of the intelligent magnetic lamp supplies power to the control chip through the first capacitor when the DC power supply is not connected, and obtains the reset signal through the control chip to detect the level change of the first pin and trigger the constant current control circuit to perform the network clearing operation, which greatly improves the efficiency and convenience of the intelligent magnetic lamp to perform the network clearing operation.

[0078] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model.
