Description

Technical Field

[0001] This utility model relates to the field of lighting, and in particular to lighting circuits and lighting lamps. Background Technology

[0002] Lighting lamps are essential electrical appliances in people's lives; they provide light for people in dimly lit environments.

[0003] Outdoor lighting typically has two modes: low brightness and high brightness. Generally, it operates in low brightness mode to provide basic illumination, while it operates in high brightness mode when people are present or during specific time periods. However, existing outdoor lighting typically draws its power from the mains, meaning both high-power and low-power lights use mains electricity. Since the low brightness mode is maintained for a relatively long time, this results in excessive consumption of mains power. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this invention provides a lighting circuit in which the low-brightness lighting module is powered by an energy storage power supply module and a solar charging module, while the high-brightness lighting module is powered by an AC mains power supply module, thereby reducing the use of AC mains power. This invention also provides a lighting lamp.

[0005] To achieve the above objectives, the present invention employs the following technical solution: A lighting circuit, comprising: A low-brightness lighting module, which emits light for illumination when in operation; A high-brightness lighting module, which emits light for illumination when in operation, and the brightness of the light emitted by the high-brightness lighting module is higher than that of the light emitted by the low-brightness lighting module; A mains power supply module is used to connect to the mains power supply to obtain electrical energy, and the mains power supply module is connected to the high-brightness lighting module to supply it with power; An energy storage power supply module, which has the ability to store electricity, is connected to the low-brightness lighting module to supply it with power; A solar charging module that can convert solar energy into electrical energy, and the solar charging module is connected to the energy storage power supply module to charge it. The system also includes a control module connected to the low-brightness lighting module and the high-brightness lighting module to control their operating states.

[0006] Using the above technical solution, when the lighting circuit is working, the control module controls the low-brightness lighting module to be in a working state or controls the high-brightness lighting module to be in a working state. Under normal circumstances, the low-brightness lighting module is controlled to be in a working state to provide low-brightness lighting. In special cases, such as when someone is present, the high-brightness lighting module is controlled to be in a working state to provide high-brightness lighting to meet the special needs. The energy of the low-brightness lighting module comes from the energy storage power supply module, and the energy of the energy storage power supply module mainly comes from the solar charging module, which can greatly reduce the use of mains power. Since the operating power of the low-brightness lighting module is lower than that of the high-brightness lighting module, in the above technical solution, the working energy of the low-brightness lighting module comes from the energy storage power supply module, and the working energy of the high-brightness lighting module comes from the mains power supply module, making the energy distribution more reasonable. Normal and special cases can be distinguished by time zones, i.e., a certain period of time is the normal case and a certain period of time is the special case; or it can be achieved by detection sensors, such as human body sensing modules.

[0007] Furthermore, the lighting circuit includes a human body sensing module, which can detect whether there is a person in its detection area and output the detection result; the control module is connected to the human body sensing module to control the working state of the low-brightness lighting module and the high-brightness lighting module according to the detection result of the human body sensing module.

[0008] By adopting the above technical solution, the lighting circuit becomes more reasonable; the detection of the human body sensing module distinguishes between the above-mentioned normal and special situations; specifically, when the human body sensing module does not detect anyone, it is in the normal situation, that is, the low-brightness lighting module is controlled to work to provide low-brightness lighting; when the human body sensing module detects someone, it is in the special situation, that is, the high-brightness lighting module is controlled to work to provide high-brightness lighting.

[0009] Furthermore, the lighting circuit includes an environmental detection module, which can detect ambient brightness and output the detection result; the control module is connected to the environmental detection module to control the working state of the low-brightness lighting module and the high-brightness lighting module according to the detection result of the environmental detection module.

[0010] By adopting the above technical solution, the lighting circuit becomes more rational. When the environment is daytime (i.e., the ambient brightness is higher than the fourth preset ambient brightness value), the lighting circuit does not need to work. When the environment is cloudy or at night (i.e., the ambient brightness is lower than the third preset ambient brightness value), the lighting circuit needs to work. That is, when the environment is daytime (i.e., the ambient brightness is higher than the fourth preset ambient brightness value), the control module controls both the low-brightness lighting module and the high-brightness lighting module to be in a non-working state. When the environment is cloudy or at night (i.e., the ambient brightness is lower than the third preset ambient brightness value), the control module controls either the low-brightness lighting module to be in a working state or controls the high-brightness lighting module to be in a working state. The third ambient brightness preset value and the fourth ambient brightness preset value may be equal or unequal. When the third ambient brightness preset value and the fourth ambient brightness preset value are unequal, the brightness represented by the third ambient brightness preset value is lower than the brightness represented by the fourth ambient brightness preset value.

[0011] Furthermore, the lighting circuit includes a mains power detection module, which can detect whether the mains power supply module is connected to the mains power and output the detection result; the control module is connected to the mains power detection module to control the working state of the high-brightness lighting module according to the detection result of the mains power detection module.

[0012] The above technical solution makes the lighting circuit more reasonable. Due to the coupling in the circuit, especially when the mains power supply module can charge the energy storage power supply module, the energy storage power supply module can also provide power to the high-brightness lighting module. However, the power consumption of the high-brightness lighting module is not large. To avoid the energy storage power supply module affecting the function of the low-brightness lighting module, a mains power detection module is set up. When no mains power is connected, the control module controls the high-brightness lighting module to be in a non-working state.

[0013] Furthermore, the mains power supply module and the energy storage power supply module charge it; A charging control module is provided between the mains power supply module and the energy storage power supply module. The control module is connected to the charging control module and controls the state of the charging control module according to the detection results of the environmental detection module to control whether a loop is established between the mains power supply module and the energy storage power supply module.

[0014] By adopting the above technical solution, the lighting circuit becomes more reasonable. Since the charging of the energy storage power supply module by the solar charging module is affected by the environment, if there are long periods of cloudy weather, the solar charging module may not be able to meet the charging needs of the energy storage power supply module. The above technical solution can use the mains power supply module to charge the energy storage power supply module as a supplementary method when the solar charging module cannot meet the charging needs of the energy storage power supply module.

[0015] Furthermore, the lighting circuit includes an energy storage detection module, which can detect the energy storage status of the energy storage power supply module and output the detection result; the control module is connected to the energy storage detection module and controls the state of the charging control module in combination with the detection result of the energy storage detection module to control whether a loop is established between the mains power supply module and the energy storage power supply module.

[0016] By adopting the above technical solution, the lighting circuit becomes more reasonable, and the energy storage detection module can detect the energy storage status of the energy storage power supply module, so that the energy storage detection module can replenish energy in a timely manner and ensure that it can stably and reliably supply power to the low-brightness lighting module.

[0017] Furthermore, the control module is configured to: when the environmental detection module detects that the ambient brightness is lower than a first preset ambient brightness value and the energy storage detection module detects that the output voltage of the energy storage power supply module is lower than a first preset voltage value, the control module controls the mains power supply module to establish a circuit with the energy storage power supply module; when the environmental detection module detects that the ambient brightness is higher than a second preset ambient brightness value, or when the energy storage detection module detects that the output voltage of the energy storage power supply module is greater than a second preset voltage value, the control module controls the circuit between the mains power supply module and the energy storage power supply module to be disconnected, wherein the first preset voltage value is lower than the second preset voltage value.

[0018] By adopting the above technical solution, the control module becomes more reasonable; when the solar charging module cannot meet the charging needs of the energy storage power supply module, the mains power supply module simply maintains the power of the energy storage power supply module between the first preset voltage value and the second preset voltage value, ensuring that the energy storage power supply module can stably and reliably supply power to the low-brightness lighting module, while minimizing the consumption of mains power. Specifically, the first preset voltage value is 3.3V, and the second preset voltage value is 3.7V; the first preset ambient brightness value and the second preset ambient brightness value can be equal or unequal. When the first preset ambient brightness value and the second preset ambient brightness value are unequal, the brightness represented by the first preset ambient brightness value is lower than the brightness represented by the second preset ambient brightness value.

[0019] Furthermore, the lighting circuit includes a low-brightness driving module, which is disposed between the low-brightness lighting module and the energy storage power supply module. The control module is connected to the low-brightness driving module and controls whether a loop is established between the low-brightness lighting module and the energy storage power supply module by controlling the state of the low-brightness driving module. The lighting circuit includes a high-brightness driving module, which is disposed between the high-brightness lighting module and the mains power supply module. The control module is connected to the high-brightness driving module and controls whether a loop is established between the high-brightness lighting module and the mains power supply module by controlling the state of the high-brightness driving module.

[0020] By adopting the above technical solution, the lighting circuit becomes more reasonable. The control module can control whether the low-brightness lighting module is in working state by controlling the low-brightness driving module; the control module can control whether the high-brightness lighting module is in working state by controlling the high-brightness driving module.

The negative terminal of the high-brightness lighting module is connected to the third switch terminal of the second controllable switch. The fourth switch terminal of the second controllable switch is connected to the negative output terminal of the mains power supply module. The high-brightness control terminal of the control module is connected to the second control terminal of the second controllable switch to control the on / off state between the third switch terminal and the fourth switch terminal of the second controllable switch.

[0022] Using the above technical solution, when the control module controls the first switch terminal and the second switch terminal of the first controllable switch to disconnect, the circuit between the low-brightness lighting module and the energy storage power supply module is disconnected, and the low-brightness lighting module is in a non-working state. When the control module controls the connection between the first switch terminal and the second switch terminal in the first controllable switch, a circuit is established between the low-brightness lighting module and the energy storage power supply module, and the low-brightness lighting module is in working state; When the control module controls the third switch terminal and the fourth switch terminal of the second controllable switch to disconnect, the circuit between the high-brightness lighting module and the mains power supply module is disconnected, and the high-brightness lighting module is in a non-working state. When the control module controls the connection between the third and fourth switch terminals of the second controllable switch, a circuit is established between the high-brightness lighting module and the mains power supply module, and the high-brightness lighting module is in working condition.

[0023] Furthermore, the first controllable switch is configured such that: when the first control terminal is at a high level, the first switch terminal and the second switch terminal are connected; when the first control terminal is at a low level, the first switch terminal and the second switch terminal are disconnected.

[0024] By adopting the above technical solution, the first controllable switch becomes more reasonable.

[0025] Furthermore, the low-brightness driving module includes a first low-brightness driving control resistor and a second low-brightness driving control resistor. The first control terminal of the first controllable switch is connected to the low-brightness control terminal of the control module through the first low-brightness driving control resistor. One end of the second low-brightness driving control resistor is connected to the end of the first low-brightness driving control resistor that is used to connect to the first control terminal of the first controllable switch, and the other end of the second low-brightness driving control resistor is connected to the second switch terminal of the first controllable switch.

[0026] By adopting the above technical solution, the low-brightness driving module is made more reasonable. When the low-brightness control terminal of the control module outputs a high level, the first switch terminal and the second switch terminal are connected, and the low-brightness lighting module is in working state. When the low-brightness control terminal of the control module outputs a low level or a high impedance state, the first switch terminal and the second switch terminal are disconnected, and the low-brightness lighting module is in non-working state.

[0027] Furthermore, the second controllable switch is configured such that: when the second control terminal is at a high level, the third switch terminal and the fourth switch terminal are connected; when the second control terminal is at a low level, the third switch terminal and the fourth switch terminal are disconnected.

[0028] The above technical solution makes the second controllable switch more reasonable.

[0029] Furthermore, the high-brightness driving module includes a first high-brightness driving control resistor and a second high-brightness driving control resistor. The second control terminal of the second controllable switch is connected to the high-brightness control terminal of the control module through the first high-brightness driving control resistor. One end of the second high-brightness driving control resistor is connected to the end of the first high-brightness driving control resistor used for connecting to the second control terminal of the second controllable switch, and the other end of the second high-brightness driving control resistor is connected to the fourth switch terminal of the second controllable switch.

[0030] By adopting the above technical solution, the high-brightness driving module is made more reasonable. When the high-brightness control terminal of the control module outputs a high level, the third switch terminal and the fourth switch terminal are connected, and the high-brightness lighting module is in working state. When the high-brightness control terminal of the control module outputs a low level or a high impedance state, the third switch terminal and the fourth switch terminal are disconnected, and the high-brightness lighting module is in non-working state.

[0031] Furthermore, the first controllable switch adopts a first MOSFET, the drain of the first MOSFET is formed as the first switching terminal of the first controllable switch, the source of the first MOSFET is formed as the second switching terminal of the first controllable switch, and the gate of the first MOSFET is formed as the first control terminal of the first controllable switch.

[0034] The above technical solution makes the charging control module more reasonable; when the control module controls the disconnection between the fifth switch terminal and the sixth switch terminal, the circuit between the mains power supply module and the energy storage power supply module is disconnected, and the mains power supply module cannot charge the energy storage power supply module. When the control module controls the connection between the fifth switch terminal and the sixth switch terminal, a circuit is established between the mains power supply module and the energy storage power supply module, and the mains power supply module charges the energy storage power supply module.

[0035] Furthermore, the third controllable switch is configured such that: when the third control terminal is at a high level, the fifth switch terminal and the sixth switch terminal are disconnected; when the third control terminal is at a low level, the fifth switch terminal and the sixth switch terminal are connected.

[0076] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0077] See Figures 1 to 7 This utility model provides a lighting circuit, including: Low-brightness lighting module 1, which is capable of emitting light for illumination when in operation; A high-brightness lighting module 2, which can emit light for illumination when in operation, and the brightness of the light emitted by the high-brightness lighting module 2 is higher than the brightness of the light emitted by the low-brightness lighting module 1; A mains power supply module 3 is used to connect to the mains power supply to obtain electrical energy, and the mains power supply module 3 is connected to the high-brightness lighting module 2 to supply it with power; Energy storage power supply module 4, which has the ability to store electricity, is connected to the low-brightness lighting module 1 to supply it with electricity; A solar charging module 5, which can convert solar energy into electrical energy, is connected to the energy storage power supply module 4 to charge it. And a control module 6, which is connected to the low-brightness lighting module 1 and the high-brightness lighting module 2 to control the working state of the low-brightness lighting module 1 and the high-brightness lighting module 2.

[0078] Using the above technical solution, when the lighting circuit is working, the control module 6 controls the low-brightness lighting module 1 to be in working state or controls the high-brightness lighting module 2 to be in working state. Under normal circumstances, the low-brightness lighting module 1 is controlled to be in working state to provide low-brightness lighting. In special cases, such as when someone is present, the high-brightness lighting module 2 is controlled to be in working state to provide high-brightness lighting to meet the special circumstances. The energy of the low-brightness lighting module 1 comes from the energy storage power supply module 4, and the energy of the energy storage power supply module 4 mainly comes from the solar charging module 5, which can greatly reduce the use of mains power. Since the operating power of the low-brightness lighting module 1 is lower than that of the high-brightness lighting module 2, in the above technical solution, the working energy of the low-brightness lighting module 1 comes from the energy storage power supply module 4, and the working energy of the high-brightness lighting module 2 comes from the mains power supply module 3, making the energy distribution more reasonable. Normal and special cases can be distinguished by time zones, i.e., a certain period of time is the normal case and a certain period of time is the special case; or it can be achieved by detection sensors, such as the human body sensing module 7.

[0079] Furthermore, the lighting circuit includes a human body sensing module 7, which can detect whether there is a person in its detection area and output the detection result; the control module 6 is connected to the human body sensing module 7 to control the working state of the low-brightness lighting module 1 and the high-brightness lighting module 2 according to the detection result of the human body sensing module 7.

[0080] By adopting the above technical solution, the lighting circuit becomes more reasonable; the detection of the human body sensing module 7 distinguishes between the above-mentioned normal and special situations; specifically, when the human body sensing module 7 does not detect a person, it is in the normal situation, that is, the low-brightness lighting module 1 is controlled to work to provide low-brightness lighting; when the human body sensing module 7 detects a person, it is in the special situation, that is, the high-brightness lighting module 2 is controlled to work to provide high-brightness lighting.

[0081] Furthermore, the lighting circuit includes an environmental detection module 8, which can detect ambient brightness and output the detection result; the control module 6 is connected to the environmental detection module 8 to control the working state of the low-brightness lighting module 1 and the high-brightness lighting module 2 according to the detection result of the environmental detection module 8.

[0082] By adopting the above technical solution, the lighting circuit becomes more rational. When the environment is daytime (i.e., the ambient brightness is higher than the fourth ambient brightness preset value), the lighting circuit does not need to work. When the environment is cloudy or at night (i.e., the ambient brightness is lower than the third ambient brightness preset value), the lighting circuit needs to work. That is, when the environment is daytime (i.e., the ambient brightness is higher than the fourth ambient brightness preset value), the control module 6 controls both the low-brightness lighting module 1 and the high-brightness lighting module 2 to be in a non-working state. When the environment is cloudy or at night (i.e., the ambient brightness is lower than the third ambient brightness preset value), the control module 6 controls either the low-brightness lighting module 1 or the high-brightness lighting module 2 to be in a working state. The third ambient brightness preset value and the fourth ambient brightness preset value may be equal or unequal. When the third ambient brightness preset value and the fourth ambient brightness preset value are unequal, the brightness represented by the third ambient brightness preset value is lower than the brightness represented by the fourth ambient brightness preset value.

[0083] Furthermore, the lighting circuit includes a mains power detection module 9, which can detect whether the mains power supply module 3 is connected to the mains power and output the detection result; the control module 6 is connected to the mains power detection module 9 to control the working state of the high-brightness lighting module 2 according to the detection result of the mains power detection module 9.

[0084] The above technical solution makes the lighting circuit more reasonable. Due to the coupling in the circuit, especially when the mains power supply module 3 can charge the energy storage power supply module 4, the energy storage power supply module 4 can also provide power to the high-brightness lighting module 2. However, the power consumption of the high-brightness lighting module 2 is not large. In order to avoid the energy storage power supply module 4 affecting the function of the low-brightness lighting module 1, the mains power detection module 9 is set up. When the mains power is not connected, the control module 6 controls the high-brightness lighting module 2 to be in a non-working state.

[0085] Furthermore, the mains power supply module 3 and the energy storage power supply module 4 charge it; A charging control module 10 is provided between the mains power supply module 3 and the energy storage power supply module 4. The control module 6 is connected to the charging control module 10 and controls the state of the charging control module 10 according to the detection result of the environmental detection module 8 to control whether a loop is established between the mains power supply module 3 and the energy storage power supply module 4.

[0086] By adopting the above technical solution, the lighting circuit becomes more reasonable. Since the charging of the energy storage power supply module 4 by the solar charging module 5 is affected by the environment, if there are long periods of cloudy weather, the solar charging module 5 may not be able to meet the charging needs of the energy storage power supply module 4. The above technical solution can use the mains power supply module 3 to charge the energy storage power supply module 4 as a supplementary method when the solar charging module 5 cannot meet the charging needs of the energy storage power supply module 4.

[0087] Furthermore, the lighting circuit includes an energy storage detection module 11, which can detect the energy storage status of the energy storage power supply module 4 and output the detection result; the control module 6 is connected to the energy storage detection module 11 and controls the state of the charging control module 10 in combination with the detection result of the energy storage detection module 11 to control whether a loop is established between the mains power supply module 3 and the energy storage power supply module 4.

[0088] By adopting the above technical solution, the lighting circuit becomes more reasonable. The energy storage detection module 11 can detect the energy storage status of the energy storage power supply module 4, so that the energy storage detection module 11 can replenish energy in time and ensure that it can stably and reliably supply power to the low-brightness lighting module 1.

[0089] Furthermore, the control module 6 is configured to: when the environmental detection module 8 detects that the ambient brightness is lower than a first preset ambient brightness value and the energy storage detection module 11 detects that the output voltage of the energy storage power supply module 4 is lower than a first preset voltage value, the control module 6 controls the mains power supply module 3 to establish a circuit with the energy storage power supply module 4; when the environmental detection module 8 detects that the ambient brightness is higher than a second preset ambient brightness value, or the energy storage detection module 11 detects that the output voltage of the energy storage power supply module 4 is greater than a second preset voltage value, the control module 6 controls the circuit between the mains power supply module 3 and the energy storage power supply module 4 to be disconnected, wherein the first preset voltage value is lower than the second preset voltage value.

[0090] By adopting the above technical solution, the control module 6 becomes more reasonable; when the solar charging module 5 cannot meet the charging needs of the energy storage power supply module 4, the mains power supply module 3 simply maintains the power of the energy storage power supply module 4 between the first voltage preset value and the second voltage preset value, ensuring that the energy storage power supply module 4 can stably and reliably supply power to the low-brightness lighting module 1, while minimizing the consumption of mains power. Specifically, the first preset voltage value is 3.3V, and the second preset voltage value is 3.7V; the first preset ambient brightness value and the second preset ambient brightness value can be equal or unequal. When the first preset ambient brightness value and the second preset ambient brightness value are unequal, the brightness represented by the first preset ambient brightness value is lower than the brightness represented by the second preset ambient brightness value.

[0091] Furthermore, the lighting circuit includes a low-brightness driving module 12, which is disposed between the low-brightness lighting module 1 and the energy storage power supply module 4. The control module 6 is connected to the low-brightness driving module 12 and controls whether a loop is established between the low-brightness lighting module 1 and the energy storage power supply module 4 by controlling the state of the low-brightness driving module 12. The lighting circuit includes a high-brightness driving module 13, which is disposed between the high-brightness lighting module 2 and the mains power supply module 3. The control module 6 is connected to the high-brightness driving module 13 and controls whether a loop is established between the high-brightness lighting module 2 and the mains power supply module 3 by controlling the state of the high-brightness driving module 13.

[0092] By adopting the above technical solution, the lighting circuit becomes more reasonable. The control module 6 can control whether the low-brightness lighting module 1 is in working state by controlling the low-brightness driving module 12; the control module 6 can control whether the high-brightness lighting module 2 is in working state by controlling the high-brightness driving module 13.

[0093] Furthermore, the low-brightness driving module 12 includes a first controllable switch 1201. The positive terminal of the low-brightness lighting module 1 is connected to the positive terminal of the energy storage power supply module 4. The negative terminal of the low-brightness lighting module 1 is connected to the first switch terminal 1201-1 of the first controllable switch 1201. The second switch terminal 1201-2 of the first controllable switch 1201 is connected to the negative terminal of the energy storage power supply module 4. The low-brightness control terminal 601 of the control module 6 is connected to the first control terminal 1201-3 of the first controllable switch 1201 to control the on / off state between the first switch terminal 1201-1 and the second switch terminal 1201-2 of the first controllable switch 1201. The high-brightness driving module 13 includes a second controllable switch 1301. The positive terminal of the high-brightness lighting module 2 is connected to the positive output terminal of the mains power supply module 3. The negative terminal of the high-brightness lighting module 2 is connected to the third switch terminal 1301-1 of the second controllable switch 1301. The fourth switch terminal 1301-2 of the second controllable switch 1301 is connected to the negative output terminal of the mains power supply module 3. The high-brightness control terminal 602 of the control module 6 is connected to the second control terminal 1301-3 of the second controllable switch 1301 to control the on / off state between the third switch terminal 1301-1 and the fourth switch terminal 1301-2 of the second controllable switch 1301.

[0094] Using the above technical solution, when the control module 6 controls the first switch terminal 1201-1 and the second switch terminal 1201-2 of the first controllable switch 1201 to disconnect, the circuit between the low-brightness lighting module 1 and the energy storage power supply module 4 is disconnected, and the low-brightness lighting module 1 is in a non-working state. When the control module 6 controls the connection between the first switch terminal 1201-1 and the second switch terminal 1201-2 in the first controllable switch 1201, a circuit is established between the low-brightness lighting module 1 and the energy storage power supply module 4, and the low-brightness lighting module 1 is in working state. When the control module 6 controls the third switch terminal 1301-1 and the fourth switch terminal 1301-2 of the second controllable switch 1301 to disconnect, the circuit between the high-brightness lighting module 2 and the mains power supply module 3 is disconnected, and the high-brightness lighting module 2 is in a non-working state. When the control module 6 controls the connection between the third switch terminal 1301-1 and the fourth switch terminal 1301-2 in the second controllable switch 1301, a circuit is established between the high-brightness lighting module 2 and the mains power supply module 3, and the high-brightness lighting module 2 is in working state.

[0095] Furthermore, the first controllable switch 1201 is configured such that: when the first control terminal 1201-3 is at a high level, the first switch terminal 1201-1 and the second switch terminal 1201-2 are connected; when the first control terminal 1201-3 is at a low level, the first switch terminal 1201-1 and the second switch terminal 1201-2 are disconnected.

[0096] The above technical solution makes the first controllable switch 1201 more reasonable.

[0097] Furthermore, the low-brightness driving module 12 includes a first low-brightness driving control resistor 1202 and a second low-brightness driving control resistor 1203. The first control terminal 1201-3 of the first controllable switch 1201 is connected to the low-brightness control terminal 601 of the control module 6 through the first low-brightness driving control resistor 1202. One end of the second low-brightness driving control resistor 1203 is connected to the end of the first low-brightness driving control resistor 1202 used for connecting to the first control terminal 1201-3 of the first controllable switch 1201, and the other end of the second low-brightness driving control resistor 1203 is connected to the second switch terminal 1201-2 of the first controllable switch 1201.

[0098] By adopting the above technical solution, the low-brightness driving module 12 becomes more reasonable. When the low-brightness control terminal 601 of the control module 6 outputs a high level, the first switch terminal 1201-1 and the second switch terminal 1201-2 are connected, and the low-brightness lighting module 1 is in a working state. When the low-brightness control terminal 601 of the control module 6 outputs a low level or a high impedance state, the first switch terminal 1201-1 and the second switch terminal 1201-2 are disconnected, and the low-brightness lighting module 1 is in a non-working state.

[0099] Furthermore, the second controllable switch 1301 is configured such that: when the second control terminal 1301-3 is at a high level, the third switch terminal 1301-1 and the fourth switch terminal 1301-2 are connected; when the second control terminal 1301-3 is at a low level, the third switch terminal 1301-1 and the fourth switch terminal 1301-2 are disconnected.

[0100] The above technical solution makes the second controllable switch 1301 more reasonable.

[0101] Furthermore, the high-brightness driving module 13 includes a first high-brightness driving control resistor 1302 and a second high-brightness driving control resistor 1303. The second control terminal 1301-3 of the second controllable switch 1301 is connected to the high-brightness control terminal 602 of the control module 6 through the first high-brightness driving control resistor 1302. One end of the second high-brightness driving control resistor 1303 is connected to the end of the first high-brightness driving control resistor 1302 used for connecting to the second control terminal 1301-3 of the second controllable switch 1301. The other end of the second high-brightness driving control resistor 1303 is connected to the fourth switch terminal 1301-2 of the second controllable switch 1301.

[0102] By adopting the above technical solution, the high-brightness driving module 13 is made more reasonable. When the high-brightness control terminal 602 of the control module 6 outputs a high level, the third switch terminal 1301-1 and the fourth switch terminal 1301-2 are connected, and the high-brightness lighting module 2 is in working state. When the high-brightness control terminal 602 of the control module 6 outputs a low level or a high impedance state, the third switch terminal 1301-1 and the fourth switch terminal 1301-2 are disconnected, and the high-brightness lighting module 2 is in non-working state.

[0103] Furthermore, the first controllable switch 1201 adopts a first MOSFET 1204, the drain of the first MOSFET 1204 is formed as the first switching terminal 1201-1 of the first controllable switch 1201, the source of the first MOSFET 1204 is formed as the second switching terminal 1201-2 of the first controllable switch 1201, and the gate of the first MOSFET 1204 is formed as the first control terminal 1201-3 of the first controllable switch 1201; The second controllable switch 1301 adopts a second MOSFET 1304.

[0104] By adopting the above technical solution, the first controllable switch 1201 and the second controllable switch 1301 are more reasonable; specifically, the first MOS transistor 1204 is an NMOS transistor; the second MOS transistor 1304 is an NMOS transistor.

[0105] Furthermore, the charging control module 10 includes a third controllable switch 1001. The positive terminal of the energy storage power supply module 4 is connected to the fifth switch terminal 1001-1 of the third controllable switch 1001. The sixth switch terminal 1001-2 of the third controllable switch 1001 is connected to the positive output terminal of the mains power supply module 3. The charging control terminal 603 of the control module 6 controls the on / off state between the fifth switch terminal 1001-1 and the sixth switch terminal 1001-2 of the third controllable switch 1001 by controlling the level state of the third control terminal 1001-3 of the third controllable switch 1001.

[0106] The above technical solution makes the charging control module 10 more reasonable; when the control module 6 controls the fifth switch terminal 1001-1 and the sixth switch terminal 1001-2 to disconnect, the circuit between the mains power supply module 3 and the energy storage power supply module 4 is disconnected, and the mains power supply module 3 cannot charge the energy storage power supply module 4. When the control module 6 controls the connection between the fifth switch terminal 1001-1 and the sixth switch terminal 1001-2, a circuit is established between the mains power supply module 3 and the energy storage power supply module 4, and the mains power supply module 3 charges the energy storage power supply module 4.

[0107] Furthermore, the third controllable switch 1001 is configured such that: when the third control terminal 1001-3 is at a high level, the fifth switch terminal 1001-1 and the sixth switch terminal 1001-2 are disconnected; when the third control terminal 1001-3 is at a low level, the fifth switch terminal 1001-1 and the sixth switch terminal 1001-2 are connected.

[0108] The above technical solution makes the third controllable switch 1001 more reasonable.

[0109] Further, the charging control module 10 includes a fourth controllable switch 1002, a first charging control resistor 1003, and a second charging control resistor 1004. One end of the first charging control resistor 1003 is connected to the sixth switch terminal 1001-2 of the third controllable switch 1001, and the other end of the first charging control resistor 1003 is connected to the third control terminal 1001-3 of the third controllable switch 1001. One end of the second charging control resistor 1004 is connected to the first charging control resistor 1003 for connection with the third controllable switch 1002. One end of the third control terminal 1001-3 of 001 is connected to the second charging control resistor 1004, and the other end of the second charging control resistor 1004 is connected to the seventh switch terminal 1002-1 of the fourth controllable switch 1002. The eighth switch terminal 1002-2 of the fourth controllable switch 1002 is grounded. The charging control terminal 603 of the control module 6 is connected to the fourth control terminal 1002-3 of the fourth controllable switch 1002 to control the on / off connection between the seventh switch terminal 1002-1 and the eighth switch terminal 1002-2 of the fourth controllable switch 1002.

[0110] By adopting the above technical solution, the charging control module 10 becomes more reasonable. When the control module 6 controls the seventh switch terminal 1002-1 and the eighth switch terminal 1002-2 of the fourth controllable switch 1002 to open, the third control terminal 1001-3 of the third controllable switch 1001 is pulled high, and the fifth switch terminal 1001-1 and the sixth switch terminal 1001-2 of the third controllable switch 1001 are opened, so the mains power supply module 3 cannot charge the energy storage power supply module 4. When the control module 6 controls the seventh switch terminal 1002-1 and the eighth switch terminal 1002-2 of the fourth controllable switch 1002 to connect, the third control terminal 1001-3 of the third controllable switch 1001 is pulled low to a low level, the fifth switch terminal 1001-1 and the sixth switch terminal 1001-2 of the third controllable switch 1001 are connected, and the mains power supply module 3 charges the energy storage power supply module 4; Furthermore, the negative output terminal of the mains power supply module 3 and the negative terminal of the energy storage power supply module 4 are grounded.

[0111] The above technical solution makes the lighting circuit more reasonable.

[0112] Furthermore, the fourth controllable switch 1002 is configured such that: when the fourth control terminal 1002-3 is at a high level, the seventh switch terminal 1002-1 is connected to the eighth switch terminal 1002-2; and when the fourth control terminal 1002-3 is at a low level or a high impedance state, the seventh switch terminal 1002-1 is disconnected from the eighth switch terminal 1002-2.

[0113] The above technical solution makes the fourth controllable switch 1002 more reasonable.

[0115] By adopting the above technical solution, the third controllable switch 1001 and the fourth controllable switch 1002 are more reasonable; specifically, the third MOS transistor 1005 is a PMOS transistor, and the transistor 1006 is an NPN transistor 1006.

[0116] Furthermore, a third charging control resistor 1007 is connected in series between the charging control terminal 603 of the control module 6 and the fourth control terminal 1002-3 of the fourth controllable switch 1002.

[0117] The above technical solution makes the charging control module 10 more reasonable.

[0118] Furthermore, the environmental detection module 8 is connected to the solar charging module 5 to collect the output voltage and / or current of the solar charging module 5 to indirectly detect the ambient brightness; Specifically, the environmental detection module 8 includes a first environmental detection resistor 801 and a second environmental detection resistor 802.

The other end of the second environmental detection resistor 802 is connected to the negative output terminal of the solar charging module 5. The connection between the first environmental detection resistor 801 and the second environmental detection resistor 802 is used to output the detection result and is connected to the environmental detection terminal 604 of the control module 6.

[0119] The above technical solution makes the environmental detection module 8 more reasonable; the first environmental detection resistor 801 and the second environmental detection resistor 802 form a voltage divider circuit module to facilitate the collection of detection data.

[0120] Furthermore, the mains power detection module 9 is connected to the mains power supply module 3 to collect the output voltage and / or current of the mains power supply module 3 in order to indirectly detect whether the mains power supply module 3 is connected to the mains power.
