Abstract

The invention discloses a power-intelligently adjustable distributed LED power supply for a railway compartment. The power-intelligently adjustable distributed LED power supply comprises a mounting plate, a shell is mounted at the top of the mounting plate, a supporting frame is mounted on the bottom wall of the inner side of the shell, a supporting plate is mounted on the inner side of the supporting frame, a base plate is mounted at the top of the supporting plate through bolts, an embedding plate is installed on the inner side of the top of the shell in an embedding mode, a top plate is installed on the top of the embedding plate, a temperature and humidity displayer is installed on the top of the top plate through bolts, a wire bunching hole seat is installed on the inner wall of the shell in a penetrating mode, and an electric wire is installed on the inner side of the wire bunching hole seat in a penetrating mode. According to the power-intelligently adjustable distributed LED power supply for the railway compartment of the invention, a transformer is installed; the power of output electric power is preset by a worker; voltage and current are converted through the transformer, so that the voltage and current are in a degree suitable for use in the compartment, the safety of electric appliances in the compartment is ensured; an operator can conveniently adjust the output power of the electric power according to needs, and the adjusted current enters a rectifier.

Description

technical field [0001] The invention relates to the technical field of LED power supplies, in particular to a distributed LED power supply for railway carriages whose power can be intelligently adjusted. Background technique [0002] The railway carriage is a structure similar to a movable house pulled by a train. It is used to place seats for the convenience of passengers. It is a very important transportation workpiece. Its appearance increases the passenger volume and meets the needs of a large number of people in transit. With the technological level The improvement of the train compartment is equipped with electronic equipment such as lights and speakers, and the electronic equipment needs a power supply to provide power for it. [0003] The defects of LED power supply in the prior art are: [0004] 1. The comparative document CN213930830U discloses an LED power supply with an electronic thermometer, "including an LED power supply box, the bottom of the LED power suppl...

AI Technical Summary

Problems solved by technology

The utility model is provided with an internal interface on the side of the main body of the LED power supply away from the control button, and at the same time, a converter is provided inside the main body of the LED power supply, and at the same time, a cooling hole and a protection device are provided on the converter, which is suitable for use. This device cannot supply power to multiple sets of electrical appliances at the same time, and the practicability of the device is not high

[0006] 3. The comparative document CN210928406U discloses a LED power supply with an alarm function, "including an LED power supply shell and an alarm unit, and an LED power supply shell: an opening is provided on the top of the LED power supply shell, and the side of the upper surface of the rear end of the LED power supply shell is aligned with the The side of the front side of the cover plate is rotatably connected, and an alarm unit is fixed on the front side of the inner bottom surface of the LED power supply shell, and a battery is fixed on the rear side of the inner bottom surface of the LED power supply shell. The alarm unit: the alarm unit includes a digital power sensor, a first fixed Column, single-chip microcomputer, horn, first baffle plate and first through hole, the digital power sensor is fixed on the front side of the battery, the first fixing column is provided with two, respectively fixed on the front side of the inner bottom surface of the LED power supply shell, the first A horn is fixed on the front side of the fixed column, and a single-chip microcomputer is fixed on the upper surface of the first fixed column, and the first baffle is fixed on the front side inside the LED power supply shell. The LED power supply with alarm function has good heat dissipation, is easy to clean, and has Power alarm function", the device lacks a structure to control the output power, which can easily lead to excessive current output and dangerous situations
