Abstract

The invention belongs to the technical field of visible light detection and particularly relates to an expressway giant advertising board intelligent lighting energy-saving control device and method. The device comprises a lens set and a visible light sensing energy-saving control device which further comprises a power supply management module, a relay, an LED lamp set, a double-element visible light illuminance detection circuit, a level switching circuit and a monostability multiple trigger circuit. The visible light sensing energy-saving control device is small in size, low in cost and convenient to mount, the double-element visible light detection circuit composed of two light dependent resistors and an inverse-phase band-pass filtering amplifying circuit is used in an innovative mode for detecting environment illuminance changing caused by vehicle lamp lighting when a vehicle passes by, interference on detection from environment illuminance and external radio frequency signals is avoided, and whether the vehicle passes by can be effectively judged.

Description

technical field [0001] The invention belongs to the technical field of visible light detection, and in particular relates to an intelligent lighting energy-saving control device and method for giant billboards on highways. Background technique [0002] At present, the most common billboards on the expressway are standing giant billboards, and there are also billboards installed in the facilities along the expressway, toll stations, service areas and bridges, in order to obtain more advertising groups and Advertising effect, advertising companies usually install floodlight high pressure sodium lamps under the billboards to provide night lighting. Therefore, when there is no vehicle passing by at night, the floodlight high-pressure sodium lamp still provides lighting, which not only fails to receive the advertising effect, but also causes waste of electric energy. [0003] Now LED lighting technology has been widely used, and its energy-saving effect, ease of control and serv...
