[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a specific embodiment of the utility model provides a structural schematic diagram of an intelligent lamp power supply control device, including a solar power supply module 1, a charge and discharge management module 2, a power module 3, a main control module 4, a light source module 5 and a power switch module 6, wherein the power module 3 includes a super capacitor 31 and a lithium battery pack 32; the charge and discharge management module 2 is respectively connected to the solar power supply module 1, the super capacitor 31 and the lithium battery pack 32, and is used to convert the charging voltage input by the solar power supply module 1 and charge the super capacitor 31, and the charge and discharge management module 2 is also used to control the discharge state of the super capacitor 31 and the lithium battery pack 32. The main control module 4 is connected to the charge and discharge management module 2, and is used to receive the charge and discharge signals of the charge and discharge management module 2 to monitor the voltage and current conditions under the charge and discharge state, and the main control module 4 can also control the charge and discharge management module 2 to adjust the discharge current and discharge power, etc.

[0027] Preferably, the charge and discharge management module 2 includes a voltage converter and a charge and discharge management chip or a charge management chip and a discharge management chip. The charge and discharge management module 2 is a prior art, and its working principle will not be described in detail here.

[0028] The supercapacitor 31 is connected in parallel with the lithium battery pack 32, and the power output ends of the supercapacitor 31 and the lithium battery pack 32 are respectively connected to the main control module 4 to ensure that the main control module 4 is powered on. The power output ends of the supercapacitor 31 and the lithium battery pack 32 are also respectively connected to the light source module 5 through the power switch module 6 to power the light source module 5. Through the wide operating temperature characteristics of the supercapacitor 31, the lighting of the lamp can also be guaranteed in low temperature weather. Even in the case of continuous rainy days, the microcurrent generated by the solar power supply module 1 can still charge the supercapacitor 31, solving the problem of not being able to store energy when natural conditions are poor. The supercapacitor 31 after energy storage can charge the lithium battery pack 32 or power electrical devices, improve energy utilization and lamp working cycle, and ensure the working performance of the lamp in low temperature and rainy days. Among them, the supercapacitor 31 is preferably a lithium ion supercapacitor, but it is not limited to this.

[0029] The main control module 4 is connected to the power switch module 6, and is used to control the power switch module 6 to switch the supercapacitor 31 or the lithium battery pack 32 to power the light source module 5 according to the timing signal and the charging and discharging signal. When there is no light or the lighting environment is poor, the charging voltage output by the solar power supply module 1 is low; the main control module 4 compares the charging voltage with the preset voltage, and if the charging voltage is lower than the preset voltage, the corresponding power switch module 6 is controlled to be turned on, so that the supercapacitor 31 can power the light source module 5 and perform timing at the same time. Based on the high-rate discharge characteristics of the supercapacitor 31, the supercapacitor 31 is controlled by the charging and discharging management module 2 to achieve full power or high power supply, thereby improving the brightness of the light source module 5 and the lighting effect of the lamp. The main control module 4 can gradually adjust the discharge power of the supercapacitor 31 during different power adjustment times within the preset first power supply time. For example, if the preset first power supply time is 2 hours, the discharge power is 100% in the 0th to 30th minute after the light is turned on, and the average discharge power is 75% in the 30th to 90th minute, etc., so that the supercapacitor 31 can supply power at full power and high power in different time periods.

[0030] When the timing time reaches the first power supply time, the main control module 4 can control the corresponding power supply switch module 6 to be turned on, so that the lithium battery pack 32 supplies power to the light source module 5 and the super capacitor 31 stops supplying power. After the first power supply time, the main control module 4 adjusts the discharge power of the lithium battery pack 32 according to different power adjustment times, so that it performs low-power discharge to ensure the normal operation of the light source module 5 and the lamp. For example, the average discharge power in the 2nd to 4th hours is 50%, the average discharge power in the 4th to 6th hours is 35%, and the average discharge power in the 6th to 12th hours is 20%. Among them, when the lithium battery pack 32 is supplying power, the super capacitor 31 can also charge the lithium battery pack 32, so that the lithium battery is in a state of shallow charge and shallow discharge, thereby increasing the service life of the lithium battery.

[0031] The utility model can realize different power supply work in different time periods through the above-mentioned power adjustment method, which can reduce the life loss of the lithium battery pack 32, increase the cycle life of the power module 3 and the endurance time of the lighting work, and the overall safety is higher, and the cycle life and maintenance-free period of the power module 3 and the lamp are longer.

[0032] It should be noted that the above-mentioned method or procedure for implementing power adjustment setting according to the preset power adjustment time is prior art. For example, the prior art CN203104930U, a high-pressure gas discharge lamp dimming electronic drive circuit, discloses that the microprocessor adjusts the output power by setting multiple delay times, thereby adjusting the brightness of the lamp.

[0033] Preferably, if Figure 2 As shown, the main control module 4 includes a timer 41, and the timing function is realized by the timer 41.

[0034] Preferably, the main control module 4 uses an MCU main controller. The model of the MCU main controller is preferably SH79F165. However, this is not a limitation and can be selected according to actual needs.

When the lighting operation starts, the main control module 4 can send a control signal to control the first power switch module 61 to turn on, so that the super capacitor 31 performs high-power power supply operation. When the timing time reaches the first power supply time, the main control module 4 can send a control signal to control the second power switch module 62 to turn on and the second power switch module 62 to turn off, so that the lithium battery pack 32 performs low-power power supply operation.

[0036] Secondly, if Figure 4 As shown, the device further includes a charging switch module 7, the control end of the charging switch module 7 is connected to the main control module 4, and the two ends of the charging switch module 7 are respectively connected to the power supply output end of the solar power supply module 1 and the power supply input end of the charge and discharge management module 2. When the lighting operation starts, the main control module 4 can control the charging switch module 7 to be disconnected to disconnect the charging circuit between the solar power supply module 1 and the charge and discharge management module 2; and at the same time control the first power supply switch module 61 to supply power to start the lighting operation of the lamp.

[0037] Preferably, the first power supply switch module 61, the second power supply switch module 62 and the charging switch module 7 are preferably triodes, MOS tubes or IGBTs, but not limited thereto.

[0038] Preferably, if Figure 5 As shown, the solar power supply module 1 includes a solar panel 11 and an MPPT solar controller 12, the input end of the MPPT solar controller 12 is connected to the solar panel 11, and the output end of the MPPT solar controller 12 is connected to the super capacitor 31 to charge the super capacitor 31. The MPPT solar controller 12 is set to automatically enter a sleep mode when the input voltage is lower than the voltage of the super capacitor 31, during which the power consumption is low, especially when there is insufficient sunlight or at night, thereby reducing the power consumption of the whole machine.

[0039] Preferably, the MPPT solar controller 123 is a prior art, and its working principle is not described in detail here. The chip model in the MPPT solar controller 12 is preferably bq24650, but it is not limited to this.

[0040] Furthermore, if Figure 6As shown, the device further includes a power display module 8, which is connected to the main control module 4. The main control module 4 controls the power display module 8 to display the corresponding power status in real time according to the battery power of the lithium battery pack 32 monitored in real time by the charge and discharge management module 2. The power display module 8 includes a plurality of power display lights, and the power proportion is displayed through the power display lights. For example, when the power of the lithium battery pack 32 is 100%, all power display lights are on; when the power of the lithium battery pack 32 is 50%, half of the power display lights are on, etc.

[0041] Preferably, the light source module 5 includes a plurality of LED lamps 81 .
