[0044] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0046] See also Figure 1 , which shows a schematic diagram of the structure of an outdoor lamp provided by an embodiment of the present invention, and is described in detail as follows:

[0047] The outdoor lamp comprises: solar energy 1, battery 2, ACDC 3, control module 4 and lighting module 5;

[0048] The output end of the solar energy 1 is connected to the input end of the storage battery 2, and the output end of the storage battery 2 is respectively connected to the output end of the ACDC 3 and the power supply end of the lighting module 5;

[0049] The input terminal of ACDC3 is connected to the AC power supply;

[0050] The control module 4 is used to control the storage battery 2 to supply power to the lighting module 5 or the ACDC3 to supply power to the lighting module 5 .

[0051] In the embodiment of the present invention, the battery 2 supplies power to the lighting module 5, and the AC power supply can also supply power to the lighting module 5 through ACDC3. The control module 4 controls one of the battery 2 or the AC power supply to supply power to the lighting module 5. When the battery 2 has insufficient battery life, it can also be powered by the AC power supply, thereby ensuring the continuity and stability of the power supply to the outdoor lamp, and will not affect the normal use of the lamp due to insufficient battery life of the battery 2, thereby improving the adaptability of the outdoor lamp.

[0052] It should be noted that the circuit structure of ACDC3 is a conventional technical means, and the details are not repeated here. The control module 4 can be a main control chip such as a single chip microcomputer, FPGA, etc., and the details are not limited here.

[0053] It should also be noted that if the charging and discharging circuit in the battery 3 is a bidirectional DCDC, the input end and the output end of the battery 3 are the same end; if the charging circuit and the discharging circuit in the battery 3 are set separately, the input end and the output end of the battery 3 are different.

[0054] In one possible implementation, reference Figure 2 The outdoor lamp may further include: a photosensitive module 6; the photosensitive module 6 is connected to the control module 4, and is used to detect the current light intensity, and send the detected light intensity to the control module 4;

[0055] The control module 4 can be specifically used for:

[0056] S101: Obtaining light intensity and voltage of battery 2;

[0057] S102 : According to the light intensity and the voltage of the battery 2 , control the battery 2 to supply power to the lighting module 5 or the ACDC3 to supply power to the lighting module 5 .

[0058] When the light is strong during the day, there is no need to turn on the light, but when the light is weak, the light needs to be turned on; the voltage of the battery 2 determines whether the battery 2 can stably supply power to the lighting module 5. Therefore, in the embodiment of the present invention, the battery 2 or ACDC3 is controlled to supply power to the lighting module 5 according to the light intensity and the voltage of the battery 2.

[0059] In a possible implementation, S102 may include:

[0060] S1021: If the voltage of the battery 2 is greater than the preset voltage and the light intensity is less than the preset intensity, control the battery 2 to supply power to the lighting module 5;

[0061] S1022: If the voltage of the battery 2 is not greater than the preset voltage and the light intensity is less than the preset intensity, control ACDC3 to supply power to the lighting module 5.

[0062] In the embodiment of the present invention, a preset intensity is set. When the light intensity is less than the preset intensity, it means that the light is weak at this time and the light needs to be turned on, that is, the lighting module 5 needs to be powered. At the same time, a preset voltage is also set. When the battery 2 is greater than the preset voltage, it means that the battery 2 can normally power the lighting module 5. The battery 2 powers the lighting module 5, and clean energy is used first to save energy and cost. When the battery 2 voltage is not greater than the preset voltage, it means that the battery 2 voltage is too low and the battery life is insufficient, and the normal operation of the lighting module 5 cannot be guaranteed. At this time, it can be switched to AC power supply to ensure the normal operation of the lighting module 5.

[0063] It should be noted that the preset voltage and preset intensity can be set according to actual application requirements and are not specifically limited here.

[0064] In a possible implementation manner, the control module 4 may also be specifically used for:

[0065] S103 : If the light intensity is not less than the preset intensity, the battery 2 and the ACDC3 are controlled not to supply power to the lighting module 5 .

[0066] Based on S1021 to S1022, when the light intensity is not less than the preset intensity, the light is sufficient and there is no need to turn on the light, that is, the lighting module 5 does not need to be powered. Therefore, the embodiment of the present invention cuts off the power supply to the lighting module 5 when the light intensity is not less than the preset intensity.

[0067] In another possible implementation, reference Figure 3 The outdoor lamp may further include: a photosensitive module 6 and a human body sensing module 7; the photosensitive module 6 is connected to the control module 4, and is used to detect the current light intensity, and send the detected light intensity to the control module 4; the human body sensing module 7 is connected to the control module 4, and is used to detect whether there is a person, and send the detected human body sensing signal to the control module 4;

[0068] The control module 4 can be specifically used for:

[0069] S201: Obtaining light intensity, voltage of battery 2 and human body sensing signal;

[0070] S202: Control the battery 2 to supply power to the lighting module 5 or the ACDC3 to supply power to the lighting module 5 according to the light intensity, the voltage of the battery 2 and the human body sensing signal.

[0071] The lighting module 5 is used for supplementary lighting, and there is no need to light up when no one is around. Based on this, the embodiment of the present invention simultaneously sets up a photosensitive module 6 and a human body sensing module 7 to control the power supply of the lighting module 5 based on the light intensity, human body sensing signal and the voltage of the battery 2 .

[0072] In a possible implementation, S202 may include:

[0073] S2021: If the voltage of the storage battery 2 is greater than the preset voltage, the light intensity is less than the preset intensity, and the human body sensing signal indicates that there is a person, then control the storage battery 2 to supply power to the lighting module 5;

[0074] S2022: If the voltage of the battery 2 is not greater than the preset voltage, the light intensity is less than the preset intensity, and the human body sensing signal indicates that there is a person, then ACDC3 is controlled to supply power to the lighting module 5.

[0075] As above, the light needs to be turned on and the lighting module 5 needs to be powered only when the light intensity is weak and there is someone. Therefore, in the embodiment of the present invention, when the light intensity is less than the preset intensity, the human body sensing signal indicates that there is someone, and the battery 2 has enough battery life, the battery 2 is controlled to power the lighting module 5, and when the battery 2 has insufficient battery life, the AC power supply is used to power the lighting module 5, thereby ensuring the continuity and stability of the power supply and improving the adaptability of the outdoor lamp.

[0076] In a possible implementation manner, the control module 4 may also be specifically used for:

[0077] S203: If the light intensity is not less than the preset intensity, or the human body sensing signal indicates that there is no one, the battery 2 and the ACDC3 are controlled not to supply power to the lighting module 5.

[0078] Based on the above, when there is sufficient light or no one is around, there is no need to turn on the lights, so the power supply to the lighting module 5 is cut off to avoid wasting resources.

[0079] In a possible implementation manner, the control module 4 may also be specifically used for:

[0080] S204: before obtaining the light intensity, the voltage of the battery 2 and the human body sensing signal, obtaining the control mode of the lamp;

[0081] S205: If the control mode of the lamp is the first mode, execute steps S201 to S202;

[0082] S206: If the control mode of the lamp is the second mode, obtain the light intensity and the voltage of the battery 2; according to the light intensity and the voltage of the battery 2, control the battery 2 to power the lighting module 5 or ACDC3 to power the lighting module 5.

[0083] In order to improve the user experience, different control modes can be set in the embodiments of the present invention. In the first control mode, the power supply of the lighting module 5 is controlled by comprehensively considering the light intensity, the voltage of the battery 2 and the human body sensing signal; in the second control mode, the power supply of the lighting module 5 is controlled only according to the light intensity and the voltage of the battery 2, so that the outdoor lamp can be suitable for various different application scenarios.

[0084] For example, in downtown areas, due to the large flow of people, in order to avoid frequent opening and closing of outdoor lamps, the second mode can be set to not judge whether there are people or not, thus improving the user experience;

[0085] For areas with less traffic, there may be no one most of the time, so there is no need to turn on the lighting. If it is turned on for a long time, it will cause unnecessary waste of resources. At this time, the human body sensing signal can be combined to turn on the lighting module 5 when there are people, and turn it off when there are no people, effectively reducing the power consumption of outdoor lighting, saving energy and avoiding waste of resources.

[0086] Based on the above, for the same outdoor lamp, the user can set different control modes according to its application occasions, so that it is suitable for different application occasions, realizes user customization, and improves the applicability of the outdoor lamp.

[0087] In a possible implementation, the specific steps of controlling the battery 2 to power the lighting module 5 or the ACDC3 to power the lighting module 5 according to the light intensity and the voltage of the battery 2 can refer to S1021 to S1022, which will not be repeated here.

[0088] In a possible implementation, the outdoor lighting fixture may further include: a wireless communication module;

[0089] The wireless communication module is connected to the control module 4 and is used for receiving the control mode of the lamp sent by the user and sending the control mode of the lamp to the control module 4 .

[0090] Exemplarily, the wireless communication module may be Bluetooth, 5G module, ZigBee, WIFI, etc.

[0091] Specifically, a wireless communication module is provided in the embodiment of the present invention, and the user can set the control mode of the outdoor lamp through a remote controller, Bluetooth, APP, etc., which is convenient for the user.

[0092] In one possible implementation, reference Figure 4 , the outdoor lamp may further include: a first switch K1 and a second switch K2;

[0093] The output end of the battery 2 is connected to the power supply end of the lighting module 5 through the first switch K1;

[0094] The output end of ACDC3 is connected to the power supply end of the lighting module 5 through the second switch K2;

[0095] Controlling the storage battery 2 to supply power to the lighting module 5 or the ACDC3 to supply power to the lighting module 5 includes:

[0096] By controlling the first switch K1 and the second switch K2 , the storage battery 2 is controlled to supply power to the lighting module 5 , or the ACDC3 is controlled to supply power to the lighting module 5 .

[0097] In the embodiment of the present invention, the power supply of the lighting module 5 can be controlled by the first switch K1 and the second switch K2. For example, when the battery 2 supplies power, the first switch K1 is closed and the second switch K2 is opened; when the AC power supply supplies power, the first switch K1 is opened and the second switch K2 is closed. The circuit structure is simple and the control is more convenient.

[0098] Meanwhile, when neither the battery 2 nor the AC power source is supplying power, the first switch K1 and the second switch K2 are controlled to be disconnected.

[0099] It should be noted that when there is sufficient light, the first switch K1 is disconnected, and the solar energy 1 charges the battery 2 to store energy. The specific control process is a conventional technical means, which will not be described in detail here.

[0100] In a possible implementation, the lighting module 5 may include: a main lighting lamp and a night light; the power supply end of the main lighting lamp and the power supply end of the night light are both connected to the power supply end of the lighting module 5. Based on the above embodiment, the control module 4 controls the battery 2 or ACDC3 to supply power to the main lighting lamp and the night light, ensuring stable power supply to the main lighting lamp and the night light.

[0101] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should be included in the protection scope of the present invention.
