Intelligent green illumination system for road tunnel

Abstract

The invention discloses an intelligent green illumination system for a road tunnel. The intelligent green illumination system comprises a software system control module, and an illumination lamp dimming module, wherein after the software system control module receives environment information parameters and vehicle information parameters, the software system control module calculates luminance and color temperatures required by each road section in a tunnel hole according to illumination design details of the road tunnel, and transmits the luminance values and the color temperature values to the illumination lamp dimming module; and after the illumination lamp dimming module receives a dimming instruction from the software system control module, the illumination lamp dimming module controls LED illumination lamps in each road section to be adjusted to the luminance values and the color temperature values set by the software system control module. The intelligent green illumination system for the road tunnel is simple and convenient in the control mode, and can intelligently control the luminance and the color temperatures in each road section in the tunnel hole according to different environment parameters and traffic stream conditions; and therefore, energy conservation is realized while lamp light penetrability in the tunnel hole can be ensured under a poor visibility condition, thereby reducing traffic accidents.

Description

technical field [0001] The invention relates to the field of lighting control in tunnels, and more specifically relates to a smart green lighting control system for road tunnels. Background technique [0002] Nowadays, tunnel lighting control methods mainly include manual control, sequential control and automatic dimming control. Manual control requires a special person to be responsible for lighting management. According to environmental factors such as different time periods and weather, the number and mode of lighting switches are subjectively determined. This control method leads to high operating costs and extremely low scientific intelligence; the timing control adjusts the brightness of the lamps according to time periods during the day and night, and this method does not consider the actual brightness requirements in the tunnel due to factors such as brightness outside the tunnel and traffic flow. Automatic control is to control the switch of each lighting circuit...

Problems solved by technology

[0003] However, at this stage, the automatic control system of tunnel lighting in China is limited to the automatic control of contrast, and has not yet involved the control of the color temperature of LED lighting fixtures. Cool white light, although it embodies the advantages of high color rendering of LED lighting fixtures in road lighting, but in environments with poor visibility such as heavy fog and rainy days, the cool white LED light is not easy to be recognized by drivers, causing people to experience LED light wear. The feeling of poor permeability, research shows that 3000K~3500K warm white light has the best penetration and recognition under low visibility conditions
