For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0040] Figure 2 is a structural schematic diagram of an outdoor power supply for display provided by an embodiment of the present invention, Figure 3 is a structural schematic diagram of an outdoor power supply for lighting provided by an embodiment of the present invention, and Figure 4 is a circuit block diagram of an outdoor power supply provided by an embodiment of the present invention. As shown in Figures 2 to 4, the outdoor power supply includes a power supply body 1, an integrated lighting and display screen 2, a control module 3 and a switch module 4.

[0041] The integrated lighting and display screen 2 is arranged on the outer wall of the power supply body 1, specifically on the front of the power supply body 1 for easy viewing. The power supply body 1 refers to the main part of the outdoor power supply, and the integrated lighting and display screen 2 refers to a display screen that integrates lighting functions, that is, a display screen that can display images and also serve as a lighting function. Existing display screens can display patterns, images, and other information according to display requirements. Depending on the display requirements, different information can be displayed, such as for example, in this embodiment, it is used to display parameters. Simply turn the display screen to a bright state and adjust it to a higher brightness to serve as a lighting device for illumination. Therefore, there is currently an integrated lighting and display screen 2 that has both display and lighting functions.

[0042] The switch module 4 is electrically connected to the input end of the control module 3, and the output end of the control module 3 is electrically connected to the integrated lighting and display screen 2. The switch module 4 is used to output a first switch signal and a second switch signal. The control module 3 is used to control the integrated lighting and display screen 2 to display based on the first switch signal, and the control module 3 is used to control the integrated lighting and display screen 2 to illuminate based on the second switch signal. Among them, the switch module 4 refers to a module that can output a first switch signal and a second switch signal. The first switch signal and the second switch signal are different electrical signals. The control module 3 refers to a functional module that performs logical control, which can be one of an MCU and an FPGA. In this embodiment, it is specifically an MCU. Since the integrated lighting and display screen 2 can perform both display and illumination, different electrical signals are output through the switch module 4. After the control module 3 recognizes the electrical signal output by the switch module 4, it controls the integrated lighting and display screen 2 to illuminate or display.

[0043] Specifically, as shown in Figures 4 and 5, the switch module 4 includes a key switch 41. The key switch 41 is used to output a first switch signal when pressed for the first time, and to output a second switch signal when pressed for the second time. The key switch 41 is a simple switch mechanism used to control certain aspects of a machine or process. The key switch 41 is usually made of a hard material, usually plastic or metal. The surface is usually flat or shaped to accommodate a person's finger or hand so that it can be easily pressed or pushed. Therefore, the user can control the lighting and display integrated screen 2 to switch between lighting and display by simply pressing the key switch 41.

[0044] The above solution, by providing an integrated lighting and display screen 2 on the power supply body 1, can switch the integrated lighting and display screen 2 for display or lighting through the switch module 4, thereby meeting the user's needs for display and lighting functions. At the same time, there is no need to use separate display screens and lighting lamps. Only one integrated lighting and display screen 2 is needed to meet both lighting and display needs. Installation is more convenient, the appearance interface is simpler, the volume of the entire machine can be greatly reduced, and the structural cost is reduced. Since the outdoor power supply only uses one integrated lighting and display screen 2, only one interface and control circuit are required internally, which makes control simpler and greatly reduces the cost of the control circuit. This solves the problem that the display screen and lighting lamp of the existing outdoor power supply are arranged separately and increase the volume of the entire machine.

[0045] Preferably, the control module 3 controls the lighting and display integrated screen 2 to illuminate at a first brightness based on the second switch signal; the switch module 4 can also output a third switch signal, and the control module 3 controls the lighting and display integrated screen 2 to illuminate at a second brightness based on the third switch signal. The first brightness and the second brightness are different brightnesses, so that the lighting and display integrated screen 2 can not only illuminate, but also illuminate at different brightnesses. The control module 3 can adjust the brightness of the lighting and display integrated screen 2 by sending PWM waves with different duty cycles. In this embodiment, the first brightness is lower than the second brightness, so that when the user needs short-distance lighting, the second switch signal can be output to make the lighting and display integrated screen 2 illuminate at low brightness, that is, weak light lighting. When the user needs long-distance lighting, the third switch signal can be output to make the lighting and display integrated screen 2 illuminate at high brightness, that is, strong light lighting.

[0046] Preferably, the switch module 4 can also output a fourth switch signal, and the control module 3 controls the lighting and display integrated screen 2 to SOS mode based on the fourth switch signal, that is, three short flashes, followed by three long flashes, and then three short flashes. The three short flashes mean that the lighting and display integrated screen 2 is lit three times in a short time, and the three long flashes mean that the lighting and display integrated screen 2 is lit three times for a long time. This is a standard distress signal, which is convenient for users to seek help outdoors.

[0047] For example, the switch module 4 includes a push button switch 41, which is used to output a first switch signal when pressed for the first time, and to output a second switch signal when pressed for the second time. The push button switch 41 is also used to output a third switch signal when pressed for the third time, and to output a fourth switch signal when pressed for the fourth time. Thus, when the user presses the push button switch 41 for the first time, the lighting and display integrated screen 2 displays the screen in the manner of a conventional display screen. When the user presses the push button switch 41 for the second time, the lighting and display integrated screen 2 performs low-light illumination. When the push button switch 41 is pressed for the third time, the lighting and display integrated screen 2 performs high-light illumination. When the push button switch 41 is pressed for the fourth time, the lighting and display integrated screen 2 is in SOS mode, so that function switching can be conveniently performed.

[0048] The following describes the structure of the integrated lighting and display screen 2 using a specific embodiment. As shown in Figures 5 and 6, the integrated lighting and display screen 2 includes an LED layer 21, which includes an LED matrix 211. The LED matrix 211 is composed of a matrix of multiple lamp beads arranged in a matrix. The control module 3 is used to control the lighting of the multiple lamp beads in the LED matrix 211 based on a first switching signal to display. The control module 3 is also used to control all the lamp beads in the LED matrix 211 to light up for illumination based on a second switching signal.

[0049] Among them, the LED layer 21 is an LED dot matrix screen, which includes an LED matrix 211 composed of multiple LED lamp beads arranged in a matrix. When different lamp beads are turned on and off, the LED layer 21 can present different pictures, so text, pictures, videos, etc. can be displayed by controlling the lighting of the lamp beads. When all the lamp beads are on, the entire lighting and display integrated screen 2 is equivalent to a white screen, and lighting can be performed at this time.

[0050] In an optional embodiment of the present invention, the integrated lighting and display screen 2 further includes an LED drive circuit 22, the outdoor power supply further includes a circuit board 5, the control module 3 is disposed on the circuit board 5, and the integrated lighting and display screen 2 further includes a control pin 8, through which the control module 3 is electrically connected to the LED drive circuit 22. The control module 3 may include an MCU, which may be mounted on the circuit board 5 via an SMT patch. The control pin 8 is made of a conductive material, and the MCU may be soldered and fixed to the control pin 8 via a trace on the circuit board 5. The other end of the control pin 8, which is away from the circuit board 5, is electrically connected to the LED drive circuit 22, thereby achieving electrical connection between the control module 3 and the LED drive circuit 22. In this embodiment, the integrated lighting and display screen 2 further includes a drive layer 23, which is composed of a printed circuit board. The LED drive circuit 22 includes a driver IC, which is mounted on the printed circuit board via an SMT patch.

[0051] Based on the above embodiment, as shown in Figures 5 and 6, the LED driving circuit 22 is electrically connected between the output end of the control module 3 and the LED matrix 211; the control module 3 is used to output a first control signal based on a first switching signal, and the LED driving circuit 22 is used to drive the plurality of lamp beads to light up and off for display based on the first control signal; the control module 3 is used to output a second control signal based on a second switching signal, and the LED driving circuit 22 is used to drive all the lamp beads to light up for illumination based on the second control signal. Among them, the LED driving circuit 22 is used to power and drive the LED matrix 211, which can drive the lamp beads to light up or turn off. The main principle of the LED driving circuit 22 is to provide appropriate current to maintain the normal operation of the LED. LED is a semiconductor device, and its working principle is to generate light through the combination of electrons and holes in the semiconductor. When using LED, it is necessary to ensure that it is provided with appropriate current, otherwise it may not light up or be damaged. The first control signal and the second control signal can be PWM waves. When the control module 3 outputs different PWM waves to the LED driving circuit 22 according to the electrical signal output by the identified switch module 4, the LED driving circuit 22 drives the lamp beads of the LED matrix 211 to light up and go out according to the PWM wave emitted by the control module 3, so that the LED matrix 211 can display information or illuminate the outside according to the planned method.

[0052] In an optional embodiment of the present invention, as shown in FIG5 , the integrated lighting and display screen 2 further includes a display screen mirror 7 , which is disposed on the surface of the LED layer 21 . The display screen mirror 7 refers to a light-transmitting layer covering the surface of the LED layer 21 and having a mirror-like effect. Since the display screen mirror 7 is disposed on the surface of the LED layer 21, it provides external protection for the LED layer 21 and allows for light transmission. Preferably, the display screen mirror 7 is made of mirror glass.

[0053] In an optional embodiment of the present invention, as shown in Figures 2 and 6, the outdoor power supply further includes a power module 6. The power module 6 can be disposed within the power supply body 1. The positive output terminal of the power module 6 is electrically connected to the positive power terminal of the LED driver circuit 22, and the negative output terminal of the power module 6 is electrically connected to the negative power terminal of the LED driver circuit 22. The power terminal of the LED matrix 211 is electrically connected to the positive output terminal of the power module 6, and the output terminal of the LED driver circuit 22 is electrically connected to the control terminal of the LED matrix 211. The power module 6 is a module that converts other forms of energy into electrical energy. Since the power module 6 is electrically connected to both the LED driver circuit 22 and the LED matrix 211, it can power both the LED driver circuit 22 and the LED matrix 211. Preferably, the power module 6 includes a battery, specifically a lithium iron phosphate battery or a ternary lithium battery.

[0054] On the basis of the above embodiments, as shown in Figures 5 and 6, the integrated lighting and display screen 2 also includes a first diode D1 and a first capacitor C1. The first capacitor C1 is connected in parallel between the output end of the LED drive circuit 22 and the positive power supply end of the LED drive circuit 22; the positive electrode of the first diode D1 is electrically connected to the output end of the LED drive circuit 22, and the negative electrode of the first diode D1 is electrically connected to the positive power supply end of the LED drive circuit 22.

[0055] Among them, since the first capacitor C1 and the first diode D1 are both electrically connected between the output end of the LED driving circuit 22 and the positive power supply end of the LED driving circuit 22, the first capacitor C1 and the first diode D1 are connected in parallel, which can realize multiple functions such as signal rectification, filtering, and voltage stabilization, and play a protective role for the LED driving circuit 22.

[0056] In an optional embodiment of the present invention, the integrated lighting and display screen 2 also includes a first resistor R1 and a first inductor L1, the first resistor R1 is connected in series between the positive output end of the power module 6 and the power end of the LED matrix 211; the first inductor L1 is connected in series between the output end of the LED drive circuit 22 and the control end of the LED matrix 211.

[0057] The LED matrix 211, by connecting the first resistor R1 in series, can limit current and balance voltage, preventing burnout and ensuring normal operation of the LED matrix 211. The first inductor L1 has energy storage and filtering functions. By connecting the first inductor L1 in series between the control terminal of the LED matrix 211 and the output terminal of the LED driver circuit 22, a filtering effect can be achieved.

[0058] In an optional embodiment of the present invention, the outdoor power supply further includes a second capacitor C2 , which is connected in parallel between the positive output terminal of the power module 6 and the negative power terminal of the power module 6 .

[0059] The second capacitor C2 can play a filtering role, stabilize the output of the power module 6, and improve the stability of the output of the power module 6.

[0060] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of the present invention can be achieved.
