[0018] As shown in Figures 1-2 , the street lamp body 10 serves as the shell of the photovoltaic street lamp 1. The specific shape of the street lamp body 10 is not limited here, and the designer can reasonably design according to actual needs; for example, the shape of the outer contour line of the street lamp body 10 can be but is not limited to a cuboid or a cylinder.

[0019] The light source 20 is used to project illuminating light. The specific form of the light source 20 is not limited here, and the designer can reasonably select according to actual needs; for example, the light source 20 can be but is not limited to an LED lamp.

[0020] The light source 20 is arranged on the street lamp body 10. The specific connection mode between the light source 20 and the street lamp body 10 is not limited here, and the designer can reasonably design according to actual needs; for example, the light source 20 can be but is not limited to detachably connected with the street lamp body 10 through at least one of screwing, clamping or inserting; for another example, the light source 20 can also be but is not limited to non-detachably connected with the street lamp body 10 through gluing or riveting.

[0021] The photovoltaic energy storage module 30 is used to convert solar energy into electrical energy on the one hand, and to store the converted electrical energy on the other hand; the photovoltaic energy storage module 30 comprises a photovoltaic panel 31 and an energy storage unit 32.

[0022] The photovoltaic panel 31 is configured to convert solar energy into electrical energy; the specific structure of the photovoltaic panel 31 is not limited here, and the designer can reasonably design according to actual needs; for example, the photovoltaic panel 31 can be but is not limited to comprising a back plate, a cell layer and a panel arranged in sequence.

[0023] The photovoltaic panel 31 is arranged on the street lamp body 10. The specific connection mode between the photovoltaic panel 31 and the street lamp body 10 is not limited here, and the designer can reasonably design according to actual needs; for example, the photovoltaic panel 31 can be but is not limited to detachably connected with the street lamp body 10 through at least one of screwing, clamping or inserting; for another example, the photovoltaic panel 31 can also be but is not limited to non-detachably connected with the street lamp body 10 through gluing or riveting.

[0024] The energy storage unit 32 is configured to store the electrical energy converted by the photovoltaic panel 31; the specific structure of the energy storage unit 32 will be introduced in detail below.

[0025] The energy storage unit 32 is arranged on the street lamp body 10. The specific connection mode between the energy storage unit 32 and the street lamp body 10 is not limited here, and the designer can reasonably design according to the actual needs; for example, the energy storage unit 32 can be, but is not limited to, detachably connected to the street lamp body 10 by at least one of the following modes: screwing, clamping or inserting; for another example, the energy storage unit 32 can also be, but is not limited to, non-detachably connected to the street lamp body 10 by gluing or riveting.

[0026] The energy storage unit 32 is electrically connected with the photovoltaic panel 31 and the light source 20. In this way, the photovoltaic panel 31 converts solar energy into electrical energy, the energy storage unit 32 stores the converted electrical energy, and the energy storage unit 32 supplies power to the light source 20 in the case of, for example, the evening, night, etc., to meet the lighting needs.

[0027] As shown in Figures 1-2 The detection control module 40 is arranged on the street lamp body 10 as a detection control unit of the photovoltaic street lamp 1.

[0028] The detection control module 40 is electrically connected with the energy storage unit 32, and the detection control module 40 is configured to adjust the output power of the energy storage unit 32 according to the light intensity of the surrounding environment to adjust the brightness of the light source 20. For example, during the daytime, the detection control module 40 detects that the light intensity of the surrounding environment is strong, the detection control module 40 can adjust the output power of the energy storage unit 32 according to the strong light intensity (corresponding to a first electric signal) and make the output power zero, so that the light source 20 is in an off state (i.e., the light source 20 is extinguished). For another example, during the evening, the detection control module 40 detects that the light intensity of the surrounding environment is weak, the detection control module 40 can adjust the output power of the energy storage unit 32 according to the weak light intensity (corresponding to a second electric signal) and make the output power a first preset power, so that the light source 20 is in a first open state (belonging to one kind of open state, at this time the light source 20 is lit, but the brightness of the light source 20 is weak). For another example, during the night, the detection control module 40 detects that the light intensity of the surrounding environment is extremely weak, the detection control module 40 can adjust the output power of the energy storage unit 32 according to the extremely weak light intensity (corresponding to a third electric signal) and make the output power a second preset power (greater than the first preset power), so that the light source 20 is in a second open state (belonging to another kind of open state, at this time the light source 20 is lit, but the brightness of the light source 20 is strong).

[0029] Based on the photovoltaic street lamp 1 in the embodiment of the present application, by designing the detection control module 40, the detection control module 40 can detect the light intensity of the surrounding environment in real time, and adjust the output power of the energy storage unit 32 according to the detected light intensity of the surrounding environment to adjust the brightness of the light source 20, so as to adapt to the power demand of different time periods, realize intelligent control, and the operation is convenient and the applicability is high.

[0030] As shown in Figure 3 The detection control module 40 comprises a light sensing element 41 and a controller 42. The light sensing element 41 is arranged on the street lamp body 10, and is configured to sense the illumination intensity of the surrounding environment. The controller 42 is arranged on the street lamp body 10, and is electrically connected with the light sensing element 41 and the energy storage unit 32. The controller 42 is configured to adjust the output power of the energy storage unit 32 according to the illumination intensity of the surrounding environment sensed by the light sensing element 41, so as to adjust the brightness of the light source 20.

[0031] The light sensing element 41 can be, but is not limited to, an illumination sensor. The specific model of the illumination sensor is not limited here, and the designer can make a reasonable selection according to actual needs. The controller 42 can be, but is not limited to, an MCU (Microcontroller Unit). The specific model of the MCU is not limited here, and the designer can make a reasonable selection according to actual needs.

[0032] For example, during the daytime, the light sensing element 41 senses a strong illumination intensity of the surrounding environment and generates a first electric signal. The controller 42 can adjust the output power of the energy storage unit 32 according to the first electric signal corresponding to the strong illumination intensity, and make the output power zero, so that the light source 20 is in the above-mentioned closed state. For another example, during the evening, the light sensing element 41 senses a weak illumination intensity of the surrounding environment and generates a second electric signal. The controller 42 can adjust the output power of the energy storage unit 32 according to the second electric signal corresponding to the weak illumination intensity, and make the output power the above-mentioned first preset power, so that the light source 20 is in the above-mentioned first open state. For another example, during the night, the light sensing element 41 senses an extremely weak illumination intensity of the surrounding environment and generates a third electric signal. The controller 42 can adjust the output power of the energy storage unit 32 according to the third electric signal corresponding to the extremely weak illumination intensity, and make the output power the above-mentioned second preset power, so that the light source 20 is in the above-mentioned second open state. It should be noted that the controller 42 has a pre-stored function corresponding relationship between the illumination intensity and the output power. The controller 42 can control the energy storage unit 32 to output different output powers according to the different illumination intensities sensed by the light sensing element 41, so as to adjust the brightness of the light source 20.

[0033] By designing the light sensing element 41, the light sensing element 41 can sense the illumination intensity of the surrounding environment in real time. By designing the controller 42, the controller 42 can adjust the output power of the energy storage unit 32 according to the illumination intensity of the surrounding environment sensed by the light sensing element 41, so as to adjust the brightness of the light source 20, thereby adapting to the power demand of different time periods, intelligently controlling, and being convenient to operate.

[0034] AsFigure 4 As shown, the energy storage unit 32 includes a main power supply 321 and a secondary power supply 322. The main power supply 321 is arranged on the street lamp body 10, and is electrically connected with the photovoltaic panel 31 and the light source 20. The secondary power supply 322 is arranged on the street lamp body 10, and is electrically connected with the photovoltaic panel 31 and the light source 20. The controller 42 is electrically connected with the main power supply 321 and the secondary power supply 322, and is configured to compare the residual power of the secondary power supply 322 with a preset threshold power. When the residual power of the secondary power supply 322 is less than or equal to the threshold power, the photovoltaic street lamp 1 is in a first power supply mode, in which the controller 42 controls the main power supply 321 to supply power to the light source 20 alone. When the residual power of the secondary power supply 322 is greater than the threshold power, the photovoltaic street lamp 1 is in a second power supply mode, in which the controller 42 controls the secondary power supply 322 to supply power to the light source 20 alone.

[0035] The main power supply 321 is one of the elements of the energy storage unit 32 for storing the electrical energy converted by the photovoltaic panel 31. The main power supply 321 can be, but is not limited to, a storage battery. The specific connection mode between the main power supply 321 and the street lamp body 10 is not limited herein, and can be reasonably designed by the designer according to actual needs. For example, the main power supply 321 can be, but is not limited to, detachably connected with the street lamp body 10 through clamping or plugging. For another example, the main power supply 321 can also be, but is not limited to, non-detachably connected with the street lamp body 10 through gluing. The secondary power supply 322 is another element of the energy storage unit 32 for storing the electrical energy converted by the photovoltaic panel 31. The secondary power supply 322 can be, but is not limited to, a storage battery. The specific connection mode between the secondary power supply 322 and the street lamp body 10 is not limited herein, and can be reasonably designed by the designer according to actual needs. For example, the secondary power supply 322 can be, but is not limited to, detachably connected with the street lamp body 10 through clamping or plugging. For another example, the secondary power supply 322 can also be, but is not limited to, non-detachably connected with the street lamp body 10 through gluing.

[0036] The controller 42 can monitor the residual power of the secondary power supply 322 in real time, and compare the residual power of the secondary power supply 322 with a preset threshold power. It should be noted that the specific meaning of the "threshold power" is not limited herein, and can be set by the designer according to actual needs. For example, the "threshold power" can be understood as the minimum power of the secondary power supply 322 that can be used to drive the light source 20 to work (e.g., at 20% of the rated power).

[0037] When the remaining power of the secondary power supply 322 is less than or equal to a preset threshold power level, the photovoltaic street lamp 1 is in a first power supply mode, in which the controller 42 controls the main power supply 321 to supply power solely to the light source 20. When the remaining power of the secondary power supply 322 is greater than the preset threshold power level, the photovoltaic street lamp 1 is in a second power supply mode, in which the controller 42 controls the secondary power supply 322 to supply power solely to the light source 20. In other words, as long as the remaining power of the secondary power supply 322 is greater than the preset threshold power level, the controller 42 will control the secondary power supply 322 to supply power to the light source 20 in priority over the main power supply 321, until the remaining power of the secondary power supply 322 is less than or equal to the preset threshold power level, at which point the controller 42 will control the secondary power supply 322 to stop supplying power to the light source 20, and as long as the light source 20 still has lighting needs, the controller 42 will control the main power supply 321 to continue supplying power to the light source 20 solely.

[0038] By designing the auxiliary power supply 322, the controller 42 compares the remaining power of the auxiliary power supply 322 with the preset threshold power, and when the remaining power of the auxiliary power supply 322 is greater than the preset threshold power, the controller 42 controls the auxiliary power supply 322 to supply power to the light source 20 alone, so that the photovoltaic street lamp 1 is in the second power supply mode in which the auxiliary power supply 322 takes precedence over the main power supply 321 in supplying power to the light source 20 alone, and until the remaining power of the auxiliary power supply 322 is less than or equal to the preset threshold power, the controller 42 will control the main power supply 321 to supply power to the light source 20 alone, so that the photovoltaic street lamp 1 is in the first power supply mode, so that the overall battery capacity of the photovoltaic street lamp 1 is larger, and it can be applied to more application scenarios.

[0039] like Figure 5 As shown, the detection and control module 40 also includes an infrared sensor 43; the infrared sensor 43 is disposed on the street lamp body 10 and is configured to sense changes in the heat of the surrounding environment. The controller 42 is electrically connected to the infrared sensor 43 and is further configured to control the on / off state of the light source 20 based on the changes in the heat of the surrounding environment sensed by the infrared sensor 43.

[0040] Among them, the infrared sensor 43 can be used to sense the heat changes in the surrounding environment; for example, when a passerby is close to the photovoltaic street lamp 1, the infrared sensor 43 senses that the heat of the surrounding environment is higher and generates a fourth electrical signal, and the controller 42 can control the light source 20 to be in the on state (that is, the light source 20 is lit) according to the fourth electrical signal corresponding to the higher heat; for another example, when a passerby is far away from the photovoltaic street lamp 1, the infrared sensor 43 senses that the heat of the surrounding environment is lower and generates a fifth electrical signal, and the controller 42 controls the light source 20 to be in the off state (that is, the light source 20 is extinguished) according to the fifth electrical signal corresponding to the lower heat.

[0041] It is to be noted that the design of the infrared sensor 43 is based on the design of the light sensing element 41, and the design of the light sensing element 41 is for the purpose of achieving the automatic brightness adjustment of the light source 20 at different time periods, while the design of the infrared sensor 43 is for the purpose of achieving energy saving. For example, the light sensing element 41 and the infrared sensor 43 cooperate with each other, and during the daytime period, as long as the light sensing element 41 senses that the light intensity of the surrounding environment is strong, even if the infrared sensor 43 senses that the heat of the surrounding environment is high, the controller 42 will still control the light source 20 to be in the off state. For another example, the light sensing element 41 and the infrared sensor 43 cooperate with each other, and during the evening period, as long as the infrared sensor 43 senses that the heat of the surrounding environment is low, even if the light sensing element 41 senses that the light intensity of the surrounding environment is weak, the controller 42 will still control the light source 20 to be in the off state. For another example, the light sensing element 41 and the infrared sensor 43 cooperate with each other, and during the night period, as long as the infrared sensor 43 senses that the heat of the surrounding environment is low, even if the light sensing element 41 senses that the light intensity of the surrounding environment is extremely weak, the controller 42 will still control the light source 20 to be in the off state. For another example, during the evening period, when the light sensing element 41 senses that the light intensity of the surrounding environment is weak, and the infrared sensor 43 senses that the heat of the surrounding environment is high, the controller 42 controls the light source 20 to be in the on state (and the auxiliary power supply 322 / the main power supply 321 supplies power to the light source 20 according to the first preset power). For another example, during the night period, when the light sensing element 41 senses that the light intensity of the surrounding environment is extremely weak, and the infrared sensor 43 senses that the heat of the surrounding environment is high, the controller 42 controls the light source 20 to be in the on state (and the auxiliary power supply 322 / the main power supply 321 supplies power to the light source 20 according to the second preset power).

[0042] As shown in Figure 1 The photovoltaic panel 31 is arranged at the top of the street lamp main body 10, so as to facilitate the photovoltaic panel 31 to receive a large area of solar energy, so as to achieve efficient conversion of solar energy to electric energy.

[0043] As shown in Figure 1As shown, the street lamp body 10 has a containing cavity (not shown in the figure); the energy storage unit 32 is arranged in the containing cavity. The street lamp body 10 also has a light-transmitting area 11; the light source 20 is located in the containing cavity and is arranged corresponding to the light-transmitting area 11. The light-transmitting area 11 can be, but is not limited to, a light-transmitting hole formed on the street lamp body 10. The photovoltaic street lamp 1 can also include a light-transmitting glass connected with the street lamp body 10 corresponding to the light-transmitting area 11. By arranging the energy storage unit 32 in the containing cavity of the street lamp body 10, the street lamp body 10 can provide good protection such as waterproof and dustproof for the energy storage unit 32; by arranging the light source 20 in the containing cavity of the street lamp body 10, the street lamp body 10 can provide good protection such as waterproof and dustproof for the light source 20; by designing the light-transmitting area 11 corresponding to the light source 20 on the street lamp body 10, the light projected by the light source 20 can effectively pass through the light-transmitting area 11 to play a lighting role.

[0044] As shown in the figure, Figure 1 The outer surface of the street lamp body 10 is provided with a pattern 50. Specifically, the pattern 50 is located below the light-transmitting area 11.

The pattern 50 can be formed on the outer surface of the street lamp body 10 by engraving or painting, etc. In this way, the charm of Yi culture can be displayed.

[0045] As shown in the figure, Figure 1 The photovoltaic street lamp 1 also includes a base 60; the base 60 is installed at the bottom of the street lamp body 10, and the base 60 is made of stainless steel. The specific connection mode between the base 60 and the street lamp body 10 is not limited herein, and the designer can reasonably design according to actual needs; for example, the base 60 can be, but is not limited to, detachably connected with the street lamp body 10 by at least one of screwing, clamping or inserting; for another example, the base 60 can also be, but is not limited to, fixedly connected with the street lamp body 10 by welding. In the embodiment of the application, the base 60 is fixedly connected with the street lamp body 10 by locking screws. By designing the base 60 to be made of stainless steel, the weight is large, the overall center of gravity of the photovoltaic body is low, the stability of the street lamp body 10 placed on the ground can be enhanced, and the stainless steel has high strength and good corrosion resistance.

[0046] As shown in the figure, Figure 1 The street lamp body 10 is made of aluminum alloy. In this way, the raw material is widely available and easy to obtain.

[0047] As shown in the figure, Figure 1 Figure 1 The photovoltaic street lamp 1 also includes a mosquito-repelling lamp 70, which is located in the containing cavity and is arranged corresponding to the light-transmitting area 11. In this way, mosquitoes can be effectively driven away from the light source 20.
