Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application 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 application.
The embodiment of the application provides a power supply circuit, which is applied to televisions, for example, different types of televisions such as an integrated television, a split television, a curved surface television and the like, and is used for supplying power to a standby load of the television, such as a signal receiving circuit, and supplying power to a non-standby load, such as a display screen.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating a first structure of a television power supply circuit 100 according to an embodiment of the present disclosure. The power supply circuit of the television includes a standby load 110, a photoelectric conversion module 120, and a power supply module 130.
The standby load 110 is a load that still needs to be operated when the television is in a standby state. For example, the standby load 110 may include a remote control receiving part, and when a user presses any one of the keys of the remote controller, the remote control receiving part may receive the remote control signal and quickly react to switch the television to the on state. In some embodiments, the standby load 110 may also include, for example, a standby indicator light, a memory, a chip, a far-field voice module, and so forth.
The photoelectric conversion module 120 is connected to the standby load 110, and the photoelectric conversion module 120 may convert light energy into electric energy, which is used to supply power to the standby load 110 when the television is in a standby state. For example, in practical applications, the photoelectric conversion module 120 may receive external ambient light energy and convert the external ambient light energy into electric energy to power the standby load 110.
The power module 130 is connected to the standby load 110, and is configured to supply power to the standby load 110 when the television is in the on state. In some embodiments, the power module 130 includes a dc-to-dc circuit for converting an input voltage into a first voltage, and the first voltage is used for supplying power to the standby load 110. The first voltage may be, for example, a voltage of 3.3V or 5V. Optionally, the power module 130 may further include a dc-dc converter circuit, an ac-dc converter circuit, and other circuits having functions of filtering, stabilizing voltage, and the like.
In the embodiment of the present application, when the television is in a standby state, the photoelectric conversion module 120 supplies power to the standby load 110, and at this time, the power supply module 130 stops supplying power; when the television is turned on, the power module 130 supplies power to the standby load 110, and at this time, the photoelectric conversion module 120 stops supplying power.
In practical implementation, since the standby load 110 is powered by the photoelectric conversion module 120 in the standby state of the television, the electric energy provided by the photoelectric conversion module 120 is converted from light energy, such as sunlight and heat radiation energy of light. Solar energy is a renewable energy source and is utilized, and the light energy of lamplight is converted from electric energy and then is recycled, so that the waste of a part of electric energy is reduced. At this time, the power module 130 stops supplying power, so the standby load 110 does not directly consume the commercial power at this time. Therefore, the power supply circuit 100 can reduce the power consumed by the television in the standby state, and achieve the effects of energy saving and environmental protection.
In other embodiments, please refer to fig. 2 exemplarily, and fig. 2 is a schematic diagram of a second structure of the television power supply circuit 100 according to an embodiment of the present application. The power supply circuit 100 further comprises a switching module 140 and an enabling module 150.
The photoelectric conversion module 120 is connected to the standby load 110 through the switch module 140. When the television is in a standby state, the switch module 140 is turned on, and the standby load 110 and the photoelectric conversion module 120 are turned on, and the standby load 110 is powered by the photoelectric conversion module 120. When the television is turned on, the switch module 140 is turned off, and the standby load 110 is disconnected from the photoelectric conversion module 120, and the power module 130 supplies power to the standby load 110.
The enabling module 150 is connected to the switch module 140 and the power module 130, and is configured to send an enabling signal to the switch module 140 and the power module 130. It is understood that the enabling module 150 may be connected to the switch module 140 and the power module 130 by wires or wirelessly. When the television enters the standby state from the power-on state, the enabling module 150 sends a first enabling signal, which may be, for example, a low level. The first enable signal is used to turn on the switch module 140, so that the photoelectric conversion module 120 supplies power to the standby load 110, and the power supply module 130 stops supplying power. When the television enters the power-on state from the standby state, the enabling module 150 sends a second enabling signal, which may be high, for example. The second enable signal is used to turn off the switch module 140 to stop the photoelectric conversion module 120 from supplying power to the standby load 110, and simultaneously start the power supply module 130 to supply power. Therefore, the enabling module 150 can control the photoelectric conversion module 120 and the power module 130 at the same time, so that the power module 130 supplies power to the standby load 110 when the television is in the on state; in the standby state, the photoelectric conversion module 120 supplies power to the standby load 110.
To describe the specific circuit structures of the photoelectric conversion module 120 and the switch module 140 in more detail, reference will be made to fig. 3, where fig. 3 is a schematic diagram of a third structure of the television power supply circuit 100 according to an embodiment of the present disclosure.
The photoelectric conversion module 120 includes a photovoltaic cell 121 and a super capacitor 122. The photovoltaic cell 121 is configured to receive light energy of an external environment and convert the light energy into electrical energy. One part of the power is used to supply power to the standby load 110 when the tv is in standby, and the other part of the power is used to charge the super capacitor 122. Alternatively, the photovoltaic cell 121 may be a group of cells or a plurality of groups of cells connected in series. When the ambient light is weak or there is no ambient light, for example, the time is at night of a day, and there is no light in the room, the photovoltaic cell 121 cannot perform photoelectric conversion, and at this time, the photovoltaic cell 121 does not operate, and the super capacitor 122 releases the electric energy charged by the photovoltaic cell 121, so as to supply power to the standby load 110 when the television is in standby.
In some embodiments, the switching module 140 includes a field effect transistor Q1. The gate of the field effect transistor Q1 is connected to the enabling module 150, and the enabling module 150 sends an enabling signal to control the switching off or on of the enabling module. For example, when the enable module 150 sends out the first enable signal, the field effect transistor Q1 is turned on; when the enable module 150 sends out the second enable signal, the fet Q1 is turned off. Meanwhile, the source of the field effect transistor Q1 is connected to the photoelectric conversion module 120, and the drain of the field effect transistor Q1 is connected to the standby load 110. When the field effect transistor Q1 is turned on, the photoelectric conversion module 120 is turned on with the standby load 110, and the photoelectric conversion module 120 supplies power to the standby load 110; when the field effect transistor Q1 is turned off, the photoelectric conversion module 120 and the standby load 110 are disconnected, and the photoelectric conversion module 120 stops supplying power to the standby load 110. Therefore, the field-effect transistor Q1 can control the photoelectric conversion module 120 to supply power to the standby load 110 from the photoelectric conversion module 120, or stop the power supply to the standby load 110 from the photoelectric conversion module 120.
In some embodiments, the protection circuit 160 is also included in the television power supply circuit 100. The protection circuit 160 is used for protecting the fet Q1, and preventing the fet Q1 from being broken down due to an excessive current or voltage carried by the fet Q1 due to current instability, static electricity, or other reasons. The protection circuit 160 includes a first resistor R1 and a second resistor R2. One end of the first resistor R1 is connected with the grid electrode of the field effect transistor Q1, and the other end of the first resistor R1 is connected with the source electrode of the field effect transistor Q1, so that the field effect transistor Q1 is shunted, and the field effect transistor Q1 is prevented from being broken down due to the fact that the field effect transistor Q1 bears overlarge current. The first end of the second resistor R2 is connected to the gate of the fet Q1, and the second end is connected to the enabling module 150, so as to divide the voltage of the fet Q1 and prevent the fet Q1 from being broken down due to the excessive voltage carried.
The embodiment of the application also provides a television, for example, the television can be different types such as an integrated television, a split television, a curved surface television and the like. For example, please refer to fig. 4, fig. 4 is a schematic structural diagram of a television 1000 according to an embodiment of the present application. The television 1000 includes the above-described television power supply circuit 100, the power board 200, the non-standby load 300, and the housing 400.
In some embodiments, one end of the power board 200 is connected to the commercial power, and the other end of the power board 200 is connected to the power module 130, and supplies power to the standby load 110 through the power module 130; the other end of the power board 200 is also connected to the non-standby load 300 and supplies power to the non-standby load 300. The power panel 200 includes an ac-to-dc voltage conversion circuit for converting the input mains voltage into a second voltage, which is used to supply power to the non-standby load 300 and the power module 130. In addition, the power board 200 may further include a circuit having functions of voltage stabilization, filtering, and the like.
The non-standby load 300 is a load that needs to be supplied with power except the standby load 110 when the television is turned on. For example, in some embodiments, the non-standby load 300 includes a load such as a liquid crystal display, a sound, or the like. The non-standby load 300 is connected to the power board 200 and the enable module 150. The non-standby load 300 and the enabling module 150 may be connected by a wire or a wireless connection. When the television is in standby, the enabling module 150 sends out a first enabling signal, which may be, for example, a low level, and the first enabling signal is used to stop the non-standby load 300; when the television is turned on, the enabling module 150 sends out a second enabling signal, which may be high level, for example, and the second enabling signal is used to start the operation of the non-standby load 300.
The housing 400 is a tv housing, and can protect the internal structure of the tv, make it beautiful, and insulate the tv. The housing 400 may be plastic or other material. The photovoltaic cell 121 is disposed on the housing 400, wherein a side of the photovoltaic cell 121 receiving light energy is disposed toward the external environment. It is understood that the photovoltaic cells 121 may be disposed on the housing 400, for example, at the location of the bezel.
In the television 1000 according to the embodiment of the present application, by disposing the photoelectric conversion module 120 in the power supply circuit 100, in the standby state of the television, the standby load 110 is powered by the photoelectric conversion module 120, and the electric energy provided by the photoelectric conversion module 120 is converted from light energy, which may be, for example, sunlight or heat radiation energy of light. Solar energy is a renewable energy source and is utilized, and the light energy of lamplight is converted from electric energy and then is recycled, so that the waste of a part of electric energy is reduced. At this time, the power module 130 stops supplying power, so the standby load 110 does not directly consume the commercial power at this time. Therefore, the power consumed by the television 1000 in the standby state can be reduced, and the effects of energy conservation and environmental protection are achieved.
The foregoing detailed description is directed to a television power supply circuit and a television provided in an embodiment of the present application, and a specific example is applied in the detailed description to explain the principles and embodiments of the present application, and the description of the foregoing embodiment is only used to help understand the method and core ideas of the present application; meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation manner and the application scope may be changed, and in summary, the content of the present specification should not be construed as a limitation to the present application.
