Intelligent dimming control device and method for LED tunnel lamp

Abstract

The invention discloses an intelligent dimming control device and method for an LED tunnel lamp. The intelligent dimming control device comprises a shell, a radar module, a Bluetooth module and a dimming control module, wherein the radar module, the Bluetooth module and the dimming control module are arranged in the shell. The side wall of the shell is provided with an LED tunnel lamp dimming control interface, and the LED tunnel lamp dimming control interface is externally connected with the LED tunnel lamp and internally connected with the dimming control module; the radar module is used fordetecting vehicle arrival data in the tunnel and transmitting the data to the Bluetooth module; the Bluetooth module receives the detection data of the radar module and transmits a control signal tothe dimming control module; the dimming control module receives the control signal of the Bluetooth module and controls the LED tunnel lamp to be turned on or turned off. According to the invention, the LED tunnel lamp can be turned on by tracking the vehicle; intelligent control of turning on of the lamp at the moment of arrival of the vehicle and turning off of the lamp at the moment of leave ofthe vehicle is realized; and the electric energy waste is effectively reduced on the premise of avoiding the potential safety hazard of the vehicle driving in a tunnel.

Description

technical field [0001] The invention belongs to the technical field of dimming control for tunnel lights, and in particular relates to an intelligent dimming control device and method for LED tunnel lights. Background technique [0002] In recent years, with the development of society, there are more and more road tunnels, and the cost of road operation is also increasing. According to statistics, about 70% of the energy consumption of road lighting is wasted in "excessive lighting", especially Tunnel electricity input. [0003] With the global energy crisis and the rise of the global protection wave, protecting the environment and saving energy have become the consensus of all mankind. In 1991, the U.S. Environmental Protection Agency first proposed the concept of the Green Lighting Program, which aims to improve lighting efficiency and reduce lighting power consumption. In 1996, my country launched the "Green Lighting Project", and it has been more than 20 years. Theref...

Problems solved by technology

In actual work, manual control is often used for tunnel lighting. Normally, all lights are turned on during the day and all lights are turned off at night. Although this method can save a certain amount of electricity, there are no vehicles during the day. When driving, there is still a large waste of electric energy when the lights in the tunnel are always on. At the same time, the lights in the tunnel are always off at night. For the period of time when there are few vehicles driving at night, the front and rear brightness in the tunnel is insufficient, and there is a safety hazard of insufficient vision for passing vehicles.
