ABSTRACT
This article starts with multiple ship collision bridge accidents in recent years, introduces the functions and design principles of aids to navigation on the bridge, and analyzes the adverse effects that bridge lighting may have on the recognizability of aids to navigation on the bridge. This impact is mainly reflected in the following three aspects: unreasonable brightness setting, improper color selection, and excessive glare phenomenon. Unreasonable brightness settings and glare phenomena can interfere with the visual perception of ship drivers, and improper color selection can mix the background light and the light color of aids to navigation on the bridge, producing new mixed color lights. All three of these effects can lead to a decrease in the recognition of aids to navigation on the bridge, thereby affecting the safety of ship navigation at night.
Based on the above analysis, the article further proposes a series of targeted optimization measures. For example, precise control of brightness can prevent strong or weak background light from affecting the recognition of aids to navigation on the bridge, ensuring that the aids to navigation on the bridge are clear and visible; using reasonable color matching can coordinate the colors of bridge lighting and aids to navigation on the bridge, improving the overall visual effect, and not confusing the signals of aids to navigation on the bridge; by introducing anti glare technology, unnecessary visual interference is reduced to ensure that aids to navigation on the bridge can still efficiently perform their navigation functions in complex background light environments. In addition, measures such as introducing laser technology, constructing AIS aids to navigation on the bridge, and strengthening supervision by relevant departments can also improve the adverse effects of bridge lighting on the recognizability of aids to navigation on the bridge to a certain extent.
