Intelligent controller of LED (light emitting diode) street lamp

Abstract

The invention discloses an intelligent controller of an LED (light emitting diode) street lamp. The intelligent controller is characterized in that a debugging signal and a light-operated signal which are respectively processed and collected by an external debugging signal acquisition circuit and a photosensitive signal acquisition circuit in the working circuit of the intelligent controller are simultaneously output to a singlechip control circuit; after the signals are operated by the singlechip control circuit, a command signal is output to control a relay in an output circuit to operate correspondingly so as to control a loading power circuit to be connected and disconnected and control the current, thereby automatically controlling the LED street lamp to be turned on and off, and controlling the luminance of the LED street lamp. The full-automatic intelligent control combining light operation and time control is carried out to the LED street lamp by the controller; the LED streetlamp is automatically turned on and off according to illumination; illumination luminance of different time intervals can be automatically adjusted according to set values; and the energy saving effect is outstanding, and the energy consumption can be saved by more than 30% compared with the existing LED street lamp adopting a switch power supply.

Description

technical field [0001] The invention relates to a control device, in particular to an intelligent controller for LED street lamps. Background technique [0002] For a long time, traditional high-pressure sodium lamps have been commonly used in road lighting, which consume a lot of energy and have a short service life. In recent years, with the rapid development of LED lighting applications, high-power LED street lights have also appeared, but most of them use switching power supplies, the output current of the power supply is constant, and there is no automatic adjustment function. Still energy consumption is bigger, affects service life. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, and provide an intelligent controller for LED street lamps that simultaneously performs light control and time control on LED lighting lamps, automatically adjusts brightness, has outstanding energy-saving effects, and prolongs...
