Technical Field
[0001] The utility model relates to the technical field of commercial lighting, and more specifically to a system using built-in PSE and PD and a stage light system provided with the same. Background Art
[0002] With the development of the Internet / Internet of Things, communication equipment is constantly being updated and replaced, and the demand is also growing. In the communication equipment installation project, the design and selection of the communication equipment power supply method and line planning are very important parts of the entire project work. Using PoE (Power Over Ethernet, active Ethernet) interface to supply power can greatly reduce the complexity and difficulty of project installation and reduce the workload of project engineering. PoE (Power over Ethernet) is "Power over Ethernet", which is a technology that can provide power to network devices through network cables. It can transmit power and data signals at the same time, so that the equipment does not need additional power cables.
[0003] The PoE power supply system consists of two parts: Power supply equipment PSE: PoE equipment that supplies power to powered devices through Ethernet, providing detection, classification, intelligent power management and other functions, such as PoE switches. Powered devices PD: such as wireless APs, portable device chargers, card readers, cameras, lighting and other powered devices.
[0004] When wiring the existing PoE system, a star structure with PSE as the center is often used. When devices with PD (such as stage lights with PoE cameras) are connected to host computers (such as computers, monitors, etc.), the common solution for transmission between the host computer and PD is: the power supply is connected to the power input port of the PSE, the host computer network port is connected to the network input port of the PSE through a network cable, and the multiple PoE output ports of the PSE are connected to the PDs of each device through network cable outputs, so that the power supply and network signals of the PD are transmitted simultaneously.
[0005] In order for stage lights to realize the tracking function of identifying specific people and objects on the target plane, and to transmit the image of the target plane to the host computer to monitor the image in real time and adjust the effect of the lighting fixture, it is necessary to apply the PoE power supply system to the stage lights. However, it is difficult to realize the star-shaped wiring structure centered on PSE in stage lights. At the same time, as the power of stage lights on the market is getting higher and higher, in order to meet the high-power requirements, thicker network cables and power cables are needed to connect, which will increase the difficulty of wiring and maintenance costs. How to change the wiring method of the PoE power supply system and stage lights is a technical problem that needs to be solved urgently in this field. Utility Model Content
[0006] The utility model aims to overcome at least one defect (shortcoming) of the above-mentioned prior art and provide a system using built-in PSE and PD to solve the problems of severe heat loss of network cables caused by wiring in the device through the existing PoE technology, increased wiring and maintenance costs due to thick power supply lines, difficulty in realizing series connection of PSE star structure in the device, and high risk of leakage.
[0007] The technical solution adopted by the utility model is to provide a system using built-in PSE and PD, which includes a device, a switching power supply located inside the device, a PSE device and at least one PD device, a power supply end and a host computer located outside the device, the power supply end is electrically connected to several of the switching power supplies, the switching power supplies power the PSE device, the host computer connects several built-in PSE devices in series through a communication connection, and the built-in PSE device is connected to the PD device for forwarding signals between the host computer and the PD device.
[0008] It is beneficial to achieve the PoE power supply effect through the switching power supply inside the device, reducing the layout of the power supply lines in the device; the current and network signals can be integrated and supplied to the PD device through the built-in PSE device and the switching power supply, and the address can be assigned to control the effect of the corresponding device; the power supply of each PD device is independently controlled through the connection between the switching power supply and the PSE device, and the devices can be connected by only one signal connection line for signal transmission, which simplifies the wiring in the device and reduces the risk of leakage; the real-time monitoring of the PD device transmission screen is realized through the host computer, so as to observe and control the device.
[0009] Furthermore, the switching power supply is electrically connected to the PSE device and the PD device respectively.
[0010] The PSE device transmits and processes signals for the PD device, which is conducive to realizing high-power power supply requirements by supplying power to the PSE device and the PD device separately through a switching power supply.
[0011] Furthermore, the PSE device is connected to the PD device, and the PSE device simultaneously supplies power and transmits signals to the PD device.
[0012] It is beneficial to use the connection wires between the built-in PSE device and the PD device to both supply power and transmit network signals. When there are different power requirements or high power requirements between various devices, the thicker wires required to bear high-power power supply can be placed directly in the device, thereby reducing the complexity of the traditional star wiring method and reducing the cost of using high-power PoE wires to connect various devices.
[0013] Further, the PSE device includes a power input port, a network input port, a PoE output port, and a non-PoE output port. The power input port is connected to the switching power supply, the network input port is connected to the host computer or the non-PoE output port of the previous PSE device, the PoE output port is connected to the PD device, and the non-PoE output port is connected to the network input port of the next PSE device.
[0014] It is beneficial to realize the electrical connection between the PSE device and the power supply end through the power input port, the signal connection between the PSE device and the host computer through the network input port, the synchronous electrical connection and signal connection between the PSE device and the PD device through the PoE output port, and the signal connection between the PSE device and the next PSE device through the non-PoE output port. Devices can be connected only through a relatively thin signal line, reducing the wiring difficulty.
[0015] Further, the PoE output port is compatible with the IEEE802.3af standard protocol, the IEEE802.3at standard protocol, or the IEEE802.3bt standard protocol.
[0016] It is beneficial to adapt to the multiple power outputs of different lamps by being compatible with the international standard protocol of PoE, thereby improving the application flexibility of the device.
[0017] Further, each PSE device is connected in parallel with a power-off normally closed relay module for controlling whether the current PSE device is connected to the signal line.

[0021] A stage light system is also provided, which includes the system using the built-in PSE and PD. Among them, the device is a stage light, which includes a chassis base, a support arm, and a lamp head pivotally connected to the support arm. The PD device is installed on the lamp head.
[0022] It is beneficial to connect multiple stage lights through a system with built-in PSE and PD. By supplying power and synchronously transmitting network signals, it is possible to avoid increasing the difficulty of wiring inside the stage light and the thickness of the wire, thereby ensuring that the heat loss inside the stage light does not increase significantly, and realizing the tracking function of the stage light and the function of real-time monitoring and adjusting the direction of the lamp.
[0023] Further, the PSE device is installed inside the lamp head.
[0024] By installing the PSE device inside the lamp head, it is beneficial to simplify the connection of the PoE wires between the lamp heads into network signal transmission wires, reducing the wiring difficulty and wire cost. At the same time, it is convenient for the wire of the PD device to pass through the lamp head housing and extend into the lamp head to connect with the PSE device.
[0025] Further, the switching power supply is located at the chassis base. The chassis base also includes a first signal network port, a second signal network port, and a switching power supply socket. Both the first signal network port and the second signal network port are connected to the PSE, and the switching power supply socket is connected to the switching power supply. The first signal network port is used to externally connect to a host computer or another stage light, the second signal network port is used to externally connect to another stage light, and the switching power supply socket is used to externally connect to a power supply terminal.
[0026] By the first signal network port, the second signal network port, and the switching power supply socket centrally arranged on the chassis base, it is beneficial to realize the centralized connection between the lamp head with built-in PSE and PD and the outside.
[0027] Further, the PD device is a camera with PoE function. The camera is installed near the light-emitting surface of the lamp head, and the PSE device is installed near the pivoting position of the lamp head and the support arm.
[0028] By the camera, it is beneficial to monitor the light spot effect of the stage light in real time to reduce the error of the light spot effect. And the PSE device is installed near the pivoting position, which is more convenient for wiring.
