The invention discloses a split type electronic navigation mark lamp (QX) and components. The conventional navigation mark lamps with an overall structure will be completely damaged when collided by vessels, the navigation mark lamps having automatic remote detection and control functions equipped with micro computer chips and those employing GPS technology are more expensive. In some navigational routes with dense navigation marks, the economic loss caused by navigation mark lamp damages is very severe. When the navigation mark lamp provided by the present invention collides with vessels, only light-emitting components whose cost only accounts to 10-20% of the total navigation mark lamp cost are damaged. Furthermore, the lamp performance can be adjusted and inspected fast and conveniently with no need to climb to the top of the three-meter floating frame, it also has higher luminance, thus large amount of expensive electronic devices and expenses can be saved during the digitalization of navigational route construction, the labor efficiency can be increased, and incidents of personal safety caused by climbing the high floating frame can be avoided. |
