Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It should be apparent that the described embodiments are only one component embodiment of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the prior art, as shown in fig. 1, an input terminal on a lamp body of the lighting device is usually directly connected to a mains wire, as shown in fig. 1, a terminal L1 on the lamp body is directly connected to a terminal L of the mains, and a terminal N1 on the lamp body is directly connected to a terminal N of the mains. Of course, the user switch is disposed at the front end of the line L terminal. However, in some cases, the live wires of the zero lines on the lamp body are connected in reverse, which results in the terminal L1 being connected to the terminal N of the utility power, and the terminal N1 being connected to the terminal L of the utility power.

In order to solve the technical problem, the embodiment of the present invention provides a circuit 100, which is disposed between the L1 terminal and the N1 terminal of the lamp body and the L terminal and the N terminal of the utility power, and is used to ensure that no power-on loop exists on the lamp body after the user switch is turned off.

The embodiment of the invention provides a lighting device, which comprises a lamp body and a circuit 100 connected with the lamp body. The lamp body may include a power supply first terminal and a power supply second terminal, one of the power supply first terminal and the power supply second terminal being connected to the first output terminal of the circuit, and the other being connected to the second output terminal of the circuit.

The first end of the power supply of the lamp body can be a live wire terminal on the lamp body, and the second end of the power supply of the lamp body can be a zero wire terminal on the lamp body; of course, the first end of the power supply may not be a live wire terminal, and the second end of the power supply may not be a neutral wire terminal, but may be the positive and negative poles of the dc power supply.

As shown in fig. 2, the circuit 100 includes a first input terminal L, a second input terminal N, a first output terminal L1, a second output terminal N1, a first electrically controlled device 20, and a second electrically controlled device 30. The first electric control device 20 comprises a first control member and a first controlled member K1, and the second electric control device 30 comprises a second control member and a second controlled member K2, wherein the first control member can control the first controlled member K1 to be turned on or off, and the second control member can control the second controlled member K2 to be turned on or off. The first controlled member K1 is connected between the first input terminal L and the first output terminal L1, and the second controlled member K2 is connected between the second input terminal N and the second output terminal N1.

The first controlled member K1 is connected between the first input terminal L and the first output terminal L1, when the first controlled member K1 is turned on, the first input terminal L and the first output terminal L1 are turned on, and when the first controlled member K1 is turned off, the first input terminal L and the first output terminal L1 are turned off. Similarly, the second controlled element K2 is connected between the second input terminal N and the second output terminal N1, when the second controlled element K2 is turned on, the second input terminal N and the second output terminal N1 are turned on, and when the second controlled element K2 is turned off, the second input terminal N and the second output terminal N1 are turned off. When a predetermined power is inputted between the first input terminal L and the second input terminal N, the first control element drives the first controlled element K1 to be conducted, and the second control element drives the second controlled element K2 to be conducted, so that the first input terminal L is conducted with the first output terminal L1, and the second input terminal N is conducted with the second output terminal N1. When the preset power input is not satisfied between the first input end L and the second input end N, the first controlled member K1 is disconnected, the second controlled member K2 is disconnected, and therefore, the first input end L is disconnected from the first output end L1, and the second input end N is disconnected from the second output end N1, so that an energizing loop is no longer provided between the first output end L1 and the second output end N1, and then the lamp bodies connected with the first output end L1 and the second output end N1 do not emit light. Therefore, the circuit 100 of the present application can ensure that there is no energizing loop on the lamp body after the user switches off the user switch connected to the lamp body.

The circuit 100 may also include a voltage regulation module 10. The voltage stabilizing module 10 is connected in parallel to the first control element and the second control element, and is configured to adjust a voltage between the first input terminal L and the second input terminal N to an operating voltage of the first control element and the second control element.

Therefore, when the preset power is input between the first input terminal L and the second input terminal N, the voltage stabilizing module 10 may also output a voltage, where the output voltage is a working voltage of the first control element and the second control element, so that the first control element drives the first controlled element K1 to be conducted, the second control element drives the second controlled element K2 to be conducted, and thus the first input terminal L is conducted with the first output terminal L1, and the second input terminal N is conducted with the second output terminal N1. When the preset power input is not satisfied between the first input terminal L and the second input terminal N, the output voltage of the voltage stabilizing module 10 cannot reach the operating voltages of the first control element and the second control element, so that the first controlled element K1 is disconnected, the second controlled element K2 is disconnected, therefore, the first input terminal L is disconnected from the first output terminal L1, the second input terminal N is disconnected from the second output terminal N1, and an energization loop is not provided between the first output terminal L1 and the second output terminal N1, so that the lamp bodies connected to the first output terminal L1 and the second output terminal N1 do not emit light. Therefore, the circuit 100 of the present application can ensure that there is no energizing loop on the lamp body after the user switches off the user switch connected to the lamp body.

The preset power input means that the voltage between the first input end L and the second input end N is a normal power supply voltage, it is easy to understand that the user switch is closed and conducted at the moment, and the first input end L and the second input end N provide power for the lamp body. The preset power input is not satisfied between the first input end L and the second input end N, namely, the voltage between the first input end L and the second input end N can not normally supply power to the lamp body, and at the moment, the user switch is closed.

In some embodiments, the power source between the first input terminal L and the second input terminal N is ac power, and for this purpose, a rectifying module BD is required to be disposed in the circuit 100, for rectifying the power source between the first input terminal L and the second input terminal N and then entering the voltage stabilizing module 10. Of course, if the power supply between the first input terminal L and the second input terminal N is dc, the rectifier module BD may not be required. In the embodiment of the present invention, one of the first input end L and the second input end N may be a live wire terminal, and the other may be a neutral wire terminal.

The rectifier module BD comprises a first rectifier input end, a second rectifier input end, a first rectifier output end and a second rectifier output end, the first rectifier input end is connected with the first input end L and the first output end L1, and the second rectifier input end is connected with the second input end N and the second output end N1. Obviously, the arrangement of the rectifier module BD does not affect the connection between the first input L and the first output L1, and the first controlled element K1 is still connected in series between the first input L and the first output L1, and similarly, the second controlled element K2 is still connected in series between the second input N and the second output N1.

The voltage stabilizing module 10 includes a first end 11 and a second end 12, the first rectifying output end is connected to the first end 11, and the second rectifying output end is connected to the second end 12 and a ground GND. Also, the first end 11 and the second end 12 of the voltage stabilizing module 10 are connected to both ends of the first control member, respectively, and to both ends of the second control member, respectively, that is, the voltage stabilizing module 10 is disposed in parallel with the first control member and is disposed in parallel with the second control member. Therefore, the alternating current power output by the first output end L1 and the second output end N1 is rectified by the rectifying module BD, and then is output to the first control element and the second control element after being subjected to voltage reduction by the voltage stabilizing module 10, the first control element is used for realizing the on-off control of the first controlled element K1, and the second control element is used for realizing the on-off control of the second controlled element K2. When the first controlled element K1 and the second controlled element K2 are turned on, the first input terminal L is directly connected to the first output terminal L1, and the second input terminal N is directly connected to the second output terminal N1, that is, the ac power between the first input terminal L and the second input terminal N is directly output to the first output terminal L1 and the second output terminal N1.

In the embodiment of the present invention, the voltage stabilizing module 10 includes a voltage stabilizing capacitor EC1, a voltage stabilizing resistor R3, and a voltage stabilizing diode ZD 1. The positive pole of the stabilizing capacitor EC1 is connected to the first terminal 11, and the additional terminal 12 of the stabilizing capacitor EC1 is connected to the second terminal. One end of the voltage stabilizing resistor R3 is connected with the first end 11, the other end is connected with the cathode of the voltage stabilizing diode ZD1, and the cathode of the voltage stabilizing diode ZD1 is connected with the second end 12. The working voltage of the zener diode ZD1 is equal to the working voltage of the first control element, and may also be equal to the working voltage of the second control element. For example, when the operating voltage of the first control element and the second control element is 5 volts, the operating voltage of the zener diode ZD1 is also 5 volts, as shown in fig. 2; for another example, when the operating voltage of the first control element and the second control element is 12 v, as shown in fig. 3, the operating voltage of the zener diode ZD2 is also 12 v. Therefore, the zener diode ZD1 with different operating voltages can be selected according to the operating voltages of the first control element and the second control element. Specifically, the circuit 100 shown in fig. 3 differs from the circuit 100 shown in fig. 2 in that the voltage regulator module 10 is different from the voltage regulator module 10 shown in fig. 2 in that the voltage regulator resistor R4 is connected in series with the zener diode ZD 2.

In the embodiment of the present invention, the first control element includes a first coil 21 and a first reverse blocking diode D1, the first coil 21 and the first reverse blocking diode D1 are arranged in parallel, an anode of the first reverse blocking diode D1 is connected to the second end 12 of the voltage regulator module 10, and a cathode of the first reverse blocking diode D1 is connected to the first end 11 of the voltage regulator module 10. When the voltage of the output of the voltage stabilizing module 10 reaches the operating voltage of the first coil 21, the first controlled member K1 is turned on, and the first reverse blocking diode D1 is used to prevent the voltage applied to the first coil 21 from being too high, so as to protect the first coil 21. Of course, in some embodiments, the first control element may not include the first reverse blocking diode D1.

In the embodiment of the present invention, the second control element includes a second coil 31 and a second reverse blocking diode D2, the second coil 31 and the second reverse blocking diode D2 are connected in parallel, an anode of the second reverse blocking diode D2 is connected to the second end 12 of the voltage regulator module 10, and a cathode of the second reverse blocking diode D2 is connected to the first end 11 of the voltage regulator module 10. When the voltage of the output of the regulator module 10 reaches the operating voltage of the second coil 31, the second controlled element K2 is turned on, and the second reverse blocking diode D2 is used to prevent the voltage applied to the second coil 31 from being too high, thereby protecting the second coil 31. Of course, in some embodiments, the first control element may not include the second reverse blocking diode D2.

The first electric control device 20 may be a first relay, and the second electric control device 30 may be a second relay, wherein the first controlled member K1 is a switch, and the second controlled member K2 may also be a switch.

In the embodiment of the present invention, the circuit 100 may further include a rc parallel module 40. One end of the rc parallel module 40 is connected to the first input terminal L, and the other end is connected to the first rectifying input terminal, so that the circuit 100 passes through the rc parallel module 40 and then enters the rectifying module BD for rectification. The rc-parallel module 40 includes a rc-CBB, a first resistor R1 and a second resistor R2. As a variation, one end of the rc parallel module 40 is connected to the second input terminal N, and the other end is connected to the second rectification input terminal.

In the circuit 100 of the embodiment of the present invention, one of the first output terminal L1 and the second output terminal N1 is used for connecting with the neutral terminal of the lamp body, and the other is used for connecting with the live terminal of the lamp body. One of the first input end L and the second input end N is connected with an external zero line (such as a commercial power zero line), and the other input end L is connected with an external live line (such as a commercial power live line). A user switch may be included in circuit 100 and may be connected in series with the external live line.
