Intelligent LED (Light-Emitting Diode) street lamp power supply system

Abstract

The invention discloses an intelligent LED (Light-Emitting Diode) street lamp power supply system. A high-voltage direct-current power supply module comprises an alternating-current power supply control unit and a direct-current unit for providing high-voltage direct-current power supply and a power line carrier modulation signal for an LED street lamp illuminating module. Through adoption of high-voltage direct-current power supply, a power adapter does not need to be provided for each street lamp, so that the problem that the service life of the adapter is not matched with the service life of an LED light source is solved, and the maintenance probability and maintenance cost of the LED street lamp are lowered greatly. Meanwhile, a very ideal lightning protection effect is achieved. A power supply and control sharing way is adopted on a high-voltage direct-current power supply circuit, and a decoder controls the brightness of the street lamps according to voltage change on a bus, so that the using quantity of cables and the cable power supply cost are reduced greatly. Moreover, a control way is simpler and more convenient.

Description

technical field [0001] The invention relates to the field of intelligent control and power supply for street lamps, in particular to an intelligent LED street lamp power supply system. Background technique [0002] The traditional LED street lamp power supply system mainly has the following problems: 1. The lightning protection of the traditional LED street lamp power supply system is not perfect; 2. Since each LED street lamp is equipped with a power adapter, the life of the adapter does not match the life of the LED light source. The maintenance probability of the traditional LED street lamp power supply system has greatly increased the maintenance cost; 3. The traditional LED street lamp power supply system has a low degree of intelligence in power distribution and fails to manage power reasonably and effectively; 4. The lighting intelligence of the traditional LED street lamp power supply system is generally not high. , failed to finely manage lighting; 5. The traditiona...

[0002] The traditional LED street lamp power supply system mainly has the following problems: 1. The lightning protection of the traditional LED street lamp power supply system is not perfect; 2. Since each LED street lamp is equipped with a power adapter, the life of the adapter does not match the life of the LED light source. The maintenance probability of the traditional LED street lamp power supply system has greatly increased the maintenance cost; 3. The traditional LED street lamp power supply system has a low degree of intelligence in power distribution and fails to manage power reasonably and effectively; 4. The lighting intelligence of the traditional LED street lamp power supply system is generally not high. , failed to finely manage lighting; 5. The traditional LED street lamp power supply system with intelligent dimming function adopts separate wiring for power supply and control, which greatly increases the cable usage; 6. The traditional LED street lamp power supply system uses AC power supply, which is different from DC power supply. Compared with the increased cable usage and the cost of power supply cables; 7. The user interface of traditional LED street lamps is single, and the degree of humanization and personalization is low
