Description

Technical Field

[0001] This utility model relates to the field of tunnel lighting power distribution, and features a distributed tunnel lighting integrated plug-in power distribution unit with a system of LED light sources and dimming driver power supplies. It is suitable for tunnel lighting systems, can optimize the installation and maintenance process, improve the safety and stability of use, and achieve integrated and quick installation. Background Technology

[0002] In the current field of tunnel lighting, LED tunnel lights are widely used. However, in existing technologies, LED light sources and dimming drivers are mostly installed in the same frame to form a tunnel light. The dimming driver is connected to the tunnel light, power supply branch device, and dimming branch device by taking out three cables. Among them, the two-core cable of the DC output end is directly connected to the LED light source.

[0003] This configuration has the following drawbacks: First, it faces the predicament of a lack of standards, leading to inconsistent installations by different construction units. Second, it requires passing the three-core power cable and the two-core dimming cable through pre-drilled holes in the side wall of the cable tray. This necessitates consideration of protective measures at the holes and the need to treat the two cables as branch lines, making two sets of branch connectors to the main power cable and the dimming bus cable respectively. This results in cumbersome wiring, long construction time, and difficulty in meeting interface standards, leading to loosening and poor sealing, which affects the stable operation of the system. Third, with the LED light source and driver power supply in the same frame, the heat generated by the LED light source will shorten the life of the electrolytic capacitors in the driver power supply. This can cause the LED light source to function normally when the driver power supply fails, requiring the entire tunnel light to be disassembled when replacing the driver power supply, increasing maintenance difficulty and requiring the interruption of the entire circuit lighting. In addition, the existing 750V DC high-voltage power supply scheme for tunnel lighting, when the light source and driver are placed together, easily leads to safety hazards such as electric shock, grounding faults, and high-voltage discharge. In street light applications, this hazard is even more pronounced when the high-voltage DC driver power supply is placed inside the street light maintenance port. Therefore, there is an urgent need for optimized tunnel lighting power distribution solutions that reduce installation difficulty, improve speed and safety. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an integrated plug-in power distribution unit for distributed tunnel lighting that combines LED light source and dimming driver power supply. By optimizing the component structure and connection method, it achieves standardized installation of tunnel lighting that is "fast, safe, efficient and of controllable quality".

The assembly process of the dimming drive power supply 1 is described below.

[0033] first step: Use two insulated wires, one end of which is soldered to the DC output terminal 141 of the power board 14, and the other end is soldered to the two DC sockets 21 of the DC two-core socket 2Z. Use three insulated wires, one end of which is soldered to the AC input terminal 142 of the power board 14, and the other end is soldered to the three power supply sockets 31 of the three-core power supply socket 3Z. Use two insulated wires, one end of which is soldered to the signal input terminal 143 of the power board 14, and the other end is soldered to the two signal jacks 41 of the two-core signal socket 4Z. Step Two: Insert the DC two-core socket 2Z into the bottom plate opening 111 of the lower shell bottom plate 11 from the inside out, and then tighten one of the DC lock nuts 25 onto the DC external thread 23; Insert the three-pin power supply socket 3Z into one of the side plate openings 121 with the bottom foot side plate 12 from the inside out, and then tighten the power supply lock nut 35 into the power supply external thread 33; Insert the signal two-core socket 4Z into one of the side plate openings 122 with the bottom foot side plate 12 from the inside out, and then tighten the signal lock nut 45 into the power supply external thread 43. Step 3: Install the power board 14 onto the lower shell base plate 11, and then assemble the two side plates 12 with feet and the upper cover plate 13 into one unit with the lower shell base plate 11, thus completing the assembly of the dimming drive power supply 1. At this time, the outer end face of one of the DC lock nuts 25 is flush with the lower surface of the fixing foot of the side plate 12 with feet, so that when the dimming drive power supply 1 is installed in the pre-drilled hole 51 on the side wall of the bridge tray 5, a dual fixing method is used, which is to fix it with the second DC lock nut 26 and the foot self-tapping screw 52 of the side plate 12 with feet.

[0034] Figure 3 The LED light source 6 is shown. It adopts a plug-in input form and does not contain a driver power supply. The DC input terminal 62 of the LED chip group 61 is respectively soldered with two tail conductors 2X1 of the DC two-core plug wire 2TX. The first end of the DC two-core plug wire 2TX is the DC two-core plug 2T. Figure 4 The power supply branch module 7 is shown. It adopts a plug-in output form. Its three power supply copper terminals 71 are respectively crimped to the three tail conductors 3X1 of the three-core power supply plug 3TX. The first end of the three-core power supply plug 3TX is the three-core power supply plug 3T. Figure 5 The signal branch module 8 is shown, which adopts a plug-in output form.

The first end of the two-core signal plug-in cable 4TX is the two-core signal plug 4T. The above describes the various components of this utility model. The following describes... Figures 6-8 This invention describes an embodiment of the integrated plug-in power distribution unit for distributed tunnel lighting, which combines an LED light source with a dimming driver power supply.

[0035] With a dimming driver power supply 1 as the core, an LED light source 6 with plug-in input, a power supply branch module 7 with plug-in output, and a signal branch module 8 are connected quickly using a plug-and-socket method to form an integrated power distribution unit. Multiple such units then constitute the entire power distribution system.

[0036] First, the external thread 23 of the DC two-pin socket 2Z on the dimming driver power supply 1 is inserted through the pre-drilled hole 51 in the side wall inside the cable tray 5, and the second DC lock nut 26 is screwed into the outside of the cable tray 5 and tightened, thus forming a connection channel between the external LED light source 6 of the cable tray 5 and the internal dimming driver power supply 1 of the cable tray 5. At this time, the fixing feet on the side plate 12 of the dimming driver power supply 1 abut against the side wall of the cable tray, and the self-tapping screws are used to fasten it to the side wall of the cable tray 5, thus completing the installation of the dimming driver power supply 1 on the cable tray 5.

[0037] After installing the LED light source 6 on the top of the tunnel outside the cable tray 5 or at the bottom of the cable tray, insert the DC two-core plug 2T into the DC two-core socket 2Z and lock it with the DC locking cap 23'. This connects the LED light source 6 to the dimming driver power supply 1 and allows it to receive the DC power output from the dimming driver power supply 1.

[0038] Inside the cable tray 5, a branch connector is made on the power supply trunk line 9 using the power supply branch module 7. Then, the power supply three-core plug 3T is inserted into the power supply three-core socket 3Z and locked with the power supply lock cap 33'. The single-phase power supply of phase, neutral and ground obtained by the power supply branch module 7 on the power supply trunk line 9 is transmitted to the dimming drive power supply 1. Inside the cable tray 5, a branch connector is made on the signal bus 10 using the signal branch module 8. Then, the two-core signal plug 4T is inserted into the two-core signal socket 4Z and locked with the signal locking cap 43'. The dimming signal obtained by the signal branch module 8 on the signal bus 10 is then transmitted to the dimming drive power supply 1.

[0039] This completes the installation of one integrated plug-in power distribution unit according to this utility model.
