Description

Technical Field

[0001] This utility model relates to the field of intelligent networked lighting, and in particular to a host power supply and networking system suitable for synchronous networking with high voltage LED driver power supplies. Background Technology

[0002] With the development of IoT technology, smart lighting technology has an increasingly widespread demand for environmental monitoring, especially for detecting the movement of objects within a given space. Among these, pyroelectric infrared sensing technology, based on Fresnel lenses to partition a detection area and using infrared pyroelectric sensors to detect cross-area movement within that area, and microwave detection technology based on the Doppler effect, are currently widely used activity detection technologies with broad application needs in the field of smart lighting. In traditional lighting equipment, to meet the need for adding intelligent functions, activity detection technology is used to detect object movement, and based on the detection results, corresponding control logic is used to control the operating state of the lighting equipment, thereby achieving intelligent control of the lighting equipment based on object movement.

[0003] In clustered lighting scenarios such as parking lot lighting, highway lighting, and staircase lighting, it is also necessary to simultaneously control multiple surrounding lights based on detection results. Existing solutions mainly use wired networking for synchronous control. Specifically, existing synchronous networking control systems include a master power supply and at least one slave power supply. The master power supply and the slave power supply each include a neutral input terminal N, a live input terminal L1, and a signal transmission terminal L'. The master power supply and the slave power supply are respectively connected to the lighting load. The neutral input terminal N and the live input terminal L1 of the master power supply and the slave power supply are respectively connected to the neutral wire and the live wire to supply power to the lighting load. The signal transmission terminal L' of the master power supply is connected to the signal transmission terminal L' of the slave power supply. The master power supply is also connected to a sensor, and supplies power to the connected lighting load based on the sensor's detection of object movement, and sends a signal to the signal transmission terminal L' of the slave power supply to supply power to the connected lighting load.

[0004] However, many existing lighting scenarios still use independently controlled power supplies, and the power supply devices are not networked for synchronous control. Traditional power supply devices only include a neutral input terminal N and a live input terminal L1. When it is necessary to network the power supply for such scenarios, all power supply devices need to be replaced. This not only increases the cost of equipment and wastes the replaced power supply devices, but also increases the construction cost of equipment installation.

[0005] Furthermore, traditional power supplies do not strictly distinguish between the neutral input terminal N and the live input terminal L1 during actual wiring. They can function normally even when the neutral input terminal N is connected to the live wire and the live input terminal L1 is connected to the neutral wire. Therefore, during equipment installation, operators are accustomed to wiring without distinguishing between the neutral input terminal N and the live input terminal L1. This leads to frequent misconnections of the neutral input terminal N, the live input terminal L1, and the signal transmission terminal L' when installing host and slave power supplies with synchronous networking capabilities. This often results in component burnout and equipment failure due to wiring errors, commonly known as "equipment crash."

[0006] For details, please refer to the following: Figure 1A and Figure 1B As shown, a portion of the circuit structure of the existing host power supply is illustrated. The host power supply is configured to turn on or off optocouplers U7 or U8 based on the detection results of the sensor. When the live wire input terminal L1 and the signal transmission terminal L' are correctly wired, the host power supply will operate normally and transmit signals to the slave power supply when optocouplers U7 or U8 are turned on. However, if incorrect wiring occurs, for example, if the signal transmission terminal L' is mistakenly connected to the neutral wire, then when optocouplers U7 or U8 are turned on, resistor R56 will be electrically connected to both the live wire and the neutral wire, creating a high voltage. This will cause resistor R56 to burn out, resulting in the host power supply failing. Utility Model Content

The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0049] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0050] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0051] Refer to the accompanying drawings in the specification of this utility model. Figures 2 to 8As shown, a high-voltage synchronous networking system 100 according to an embodiment of the present invention is illustrated. The high-voltage synchronous networking system 100 includes a host power supply 10 suitable for high-voltage synchronous networking with LED driver power supplies and at least one slave power supply 20. The slave power supply 20 can be an existing ordinary power supply with only two input terminals: a live wire connection terminal and a neutral wire connection terminal. When one of the two input terminals is connected to the host power supply 10 suitable for high-voltage synchronous networking with LED driver power supplies, it outputs power to the corresponding light-emitting load under the control of the host power supply 10 suitable for high-voltage synchronous networking with LED driver power supplies. In other words, the high-voltage synchronous networking system 100 can use the existing power supply equipment as the slave power supply 20 without replacing the existing power supply equipment, thereby enabling the networking transformation of the existing power supply equipment and effectively reducing the equipment cost and labor cost of networking the power supply equipment. Furthermore, the high-voltage synchronous networking system 100 can also avoid the problem of machine failure caused by incorrect wiring. In other words, the high-voltage synchronous networking system 100 will not fail even if it is incorrectly wired, thus effectively avoiding equipment damage caused by installation and operation errors.

[0052] Specifically, the host power supply 10 suitable for high-voltage synchronization networking with the LED driver power supply includes a live wire connection terminal 101, a neutral wire connection terminal 102, and a slave connection terminal 103. The live wire connection terminal 101 and the neutral wire connection terminal 102 are adapted to connect to the corresponding live wire and neutral wire, so that the host power supply 10 suitable for high-voltage synchronization networking with the LED driver power supply is suitable for supplying power to the corresponding light-emitting load. The host power supply 10 suitable for high-voltage synchronization networking with the LED driver power supply includes a host power supply module 11 and a switching circuit 12. The host power supply module 11 is powered and connected to the live wire connection terminal 101 and the neutral wire connection terminal 102 and has a host load connection terminal 104 and a main control module 111. The main control module 111 has a sensing connection terminal and can control the output of the host load connection terminal 104 according to the corresponding detection result. The switching circuit 12 includes a first terminal 121, a second terminal 122, and a control terminal 123. This utility model provides two different wiring methods, corresponding to... Figure 2 and Figure 3 The first wiring method shown is wherein the first terminal 121 is electrically connected to the neutral terminal 102, corresponding to Figure 4 and Figure 5In the second wiring method shown, the first terminal 121 is electrically connected to the live wire connection terminal 101, and the second terminal 122 is electrically connected to the slave connection terminal 103. The control terminal 123 is electrically connected to the master control module 111 and is controlled by the master control module 111 to turn the first terminal 121 and the second terminal 122 on or off according to the corresponding detection results. When the first terminal 121 and the second terminal 122 are on, corresponding to the first wiring method, the slave connection terminal 103 is the neutral wire connection port. When one input terminal of the traditional power supply is connected to the slave connection terminal 103, it is equivalent to being connected to the neutral wire. Corresponding to the second wiring method, the slave connection terminal 103 is equivalent to the live wire connection port. When one input terminal of the traditional power supply is connected to the slave connection terminal 103, it is equivalent to being connected to the live wire. Therefore, the host power supply 10 suitable for high-voltage synchronous networking with LED driver power supply can use the traditional power supply as a slave to form a network transformation of the traditional power supply.

[0053] Further, the slave power supply 20 includes a first connection terminal 201, a second connection terminal 202, and a slave load connection terminal 203. The first connection terminal 201 is electrically connected to the slave connection terminal 103 of the host power supply 10, which is suitable for high-voltage synchronous networking with the LED driver power supply. Corresponding to the first wiring method and the second wiring method, the second connection terminal 202 is connected to the neutral wire or the live wire. Figure 2 and Figure 3 In the first wiring configuration shown, the first terminal 121 of the switch circuit 12 is electrically connected to the neutral terminal 102, and the second terminal 202 is connected to the live wire, specifically corresponding to... Figure 4 and Figure 5 In the second wiring method shown, the first terminal 121 of the switching circuit 12 is electrically connected to the live wire connection terminal 101, and the second connection terminal 202 is connected to the neutral wire. When the first terminal 121 and the second terminal 122 of the switching circuit 12 are connected, the first connection terminal 201 and the second connection terminal 202 of the slave power supply 20 are respectively connected to the live wire and the neutral wire, and can output current from the slave load connection terminal 203 to supply power to the corresponding light-emitting load. In this way, the synchronous networking of the host power supply 10 and the slave power supply 20, which is suitable for high-voltage synchronous networking with the LED driver power supply, is realized when the slave power supply 20 has only two input terminals: the live wire connection terminal and the neutral wire connection terminal.

[0054] It is worth mentioning that, in the event that the host power supply 10 and / or the slave power supply 20, which are adapted to be networked synchronously with the high voltage of the LED driver power supply, are misconnected, the host power supply 10 and the slave power supply 20 will not explode.

[0055] Specifically, corresponding to the first wiring method, that is, the first terminal 121 of the switch circuit 12 is electrically connected to the neutral terminal 102. When the live terminal 101 and the neutral terminal 102 are correctly wired, that is, the live terminal 101 is connected to the live wire and the neutral terminal 102 is connected to the neutral wire. When the second terminal 202 is mistakenly connected to the neutral wire, it is equivalent to both the first terminal 201 and the second terminal 202 being connected to the neutral wire. The slave power supply 20 will not work and will not explode. When the second terminal 202 is connected to the live wire, it is equivalent to the first terminal 201 of the slave power supply 20 being connected to the neutral wire and the second terminal 202 being connected to the neutral wire. When the slave power supply 20 is connected to the live wire, it will not explode if it operates normally. When the live wire connection 101 and the neutral wire connection 102 are reversed (i.e., the live wire connection 101 is connected to the neutral wire and the neutral wire connection 102 is connected to the live wire), and the second connection 202 is connected to the live wire, it is equivalent to both the first connection 201 and the second connection 202 of the slave power supply 20 being connected to the live wire, and the slave power supply 20 will not operate and will not explode. When the second connection 202 is connected to the neutral wire, it is equivalent to the first connection 201 of the slave power supply 20 being connected to the live wire and the second connection 202 being connected to the neutral wire, and the slave power supply 20 will operate normally and will not explode.

[0056] Corresponding to the second wiring method, that is, the first terminal 121 of the switch circuit 12 is electrically connected to the live wire connection terminal 101. When the live wire connection terminal 101 and the neutral wire connection terminal 102 are correctly wired, that is, the live wire connection terminal 101 is connected to the live wire and the neutral wire connection terminal 102 is connected to the neutral wire. When the second connection terminal 202 is connected to the live wire, it is equivalent to both the first connection terminal 201 and the second connection terminal 202 being connected to the live wire. The slave power supply 20 will not work and will not explode. When the second connection terminal 202 is connected to the neutral wire, then the first connection terminal 201 is connected to the live wire, and the second connection terminal 202 is connected to the neutral wire. When the live wire connection 101 and the neutral wire connection 102 are reversed (i.e., the live wire connection 101 is connected to the neutral wire and the neutral wire connection 102 is connected to the live wire), and when the second connection 202 is connected to the neutral wire, it is equivalent to both the first connection 201 and the second connection 202 being connected to the neutral wire, and the slave power supply 20 will not work and will not explode. When the second connection 202 is connected to the live wire, it is equivalent to the first connection 201 being connected to the neutral wire and the second connection 202 being connected to the live wire, and the slave power supply 20 will work normally and will not explode.

[0057] It is worth mentioning that when the main control module 111 receives a detection result indicating that an object is active, it controls the output current of the host load connection terminal 104, and can subsequently control the output of the host load connection terminal 104 based on the corresponding detection result. For example, when the corresponding detection result changes from having an object active to not having an object active, the output of the host load connection terminal 104 is delayed and stopped, or the corresponding output power is limited so that the corresponding light-emitting load is adjusted to a low brightness state.

[0058] In particular, in this embodiment of the present invention, detailed reference is made. Figure 6 and Figure 7As shown, the host power supply 10, suitable for high-voltage synchronous networking with the LED driver power supply, further includes an optocoupler 13. The optocoupler 13 includes an input element 131 and an output element 132. The input element 131 has a positive terminal 1311 and a negative terminal 1312. The positive terminal 1311 is electrically connected to the live wire terminal 101, and the negative terminal 1312 is electrically connected to the slave terminal 103. One end 1321 of the output element 132 is electrically connected to the main control module 111, and the other end 1322 is grounded. When the first terminal 121 and the second terminal 122 of the switching circuit 12 are connected, it is equivalent to the positive terminal 1311 and the negative terminal 1312 of the input element 131 being connected to the live wire and the neutral wire, thus conducting, so that the output element 132 of the optocoupler 13 outputs a feedback signal to the main control module 111.

[0059] It is worth mentioning that even when the host power supply 10, which is suitable for high-voltage synchronous networking with the LED driver power supply, is misconnected, the host power supply 10 will not explode.
