Abstract

The invention discloses a power supply system for centralized control of LED (light emitting diode) street lamps. The power supply system comprises more than one LED street lamp. The power supply system further comprises an independent power supply cabinet, wherein an LED power supply is arranged in the power supply cabinet, and the LED power supply supplies power to each LED street lamp respectively through a group of independent power lines. By using the power supply system for centralized control of the LED street lamps, the temperature of the work environment of the power supply is normal temperature, thus the problem of high temperature rise of the power supply mounted on a light fitting is solved, and the service life and the reliability of the power supply can be greatly increased. Through the centralized control method, water-proof and lightning protection measures can be conveniently adopted. By using a high-voltage constant-current power supply method, remote driving of the LED street lamps is realized, and the line loss is reduced. Meanwhile, through an electric carrier remote control technology, the LED street lamps can be intelligently and conveniently monitored; stepless light regulation, failure detection and other functions can be conveniently realized; and the LED driving power supply is more convenient to repair and maintain, and can be maintained and replaced in time.

Description

technical field [0001] The invention discloses a centralized control LED street lamp power supply system, in particular a centralized control LED street lamp power supply system controlled by a power carrier. Background technique [0002] With the development of LED lighting technology, LED lighting devices are more and more widely used in people's daily life. LED street lights are a typical application of LED lighting devices. The current LED street lamp power supply is installed on the outdoor lamps. On the one hand, the power supply is affected by the temperature rise of the lamp and the superposition of the temperature rise of the power supply itself, which makes the working environment temperature of the power supply higher, which makes the service life and reliability of the power supply Wait for a big discount. On the other hand, outdoor installation has high requirements on the lightning protection level of the power supply, and the power supply is easily damaged by...
