What does navigation light mean
Navigation beacon lights, as the name suggests, are marker lights on the route, generally a type of beacon light installed on some navigation beacons and buoys.
Due to the limitations of the sea or river, the navigation lights generally use solar power, equipped with solar panels and batteries. In order to deal with the bad weather on the sea surface, the waterproof and airtightness of the navigation lights and the endurance are particularly important. Generally, the protection level should be IP65 and above, and the battery life should be more than one week. The function of the beacon light is to warn of obstacles on the route. It is required to emit light at a certain flash frequency at night, with a fixed color and light intensity requirement: the frequency is 20-60 times/min; red, green and white are the main ones, red Represents the right side, white is a cone, and green represents the left side (the left and right direction is the direction facing the lower reaches of the Yangtze River).
Navigation lights are different from aviation obstruction lights. They are mainly installed on navigation marks on the river surface, while aviation obstruction lights are mainly installed on obstacles on the ground. This is the most intuitive difference. But they are the same. The main technical parameters and standard requirements are almost the same, but they have their own special attributes because of the different use scenes: the endurance and waterproofness of the navigation lights are the key points, and the brightness of the aviation obstruction lights is the key point. In fact, if you understand this, and then refer to the standard requirements of MT/H6012-2015 "Aviation Obstruction Lights", it is not difficult to select a suitable obstruction light.
