Abstract

The invention discloses a bridge navigating mark. The bridge navigating mark comprises a mark board body and a light-emitting component, wherein the light-emitting component is arranged on the surface of the mark board body, the mark board body comprises a frame and a plurality of air guide plates, air guide plates are parallel with one another and are arranged inside the frame, an included angle which is smaller than 90 degrees is formed by air guide plates and the horizontal face, the light-emitting component comprises an aluminium-based circuit board, a light-emitting diode (LED) heat-dissipating device, a high-power LED lamp and a light source controller, the LED heat-dissipating device is arranged on the aluminium-based circuit board, the high-power LED lamp is packaged inside the LED heat-dissipating device, and the light source controller is used for controlling the light intensity and the flash cycle of the high-power LED lamp. By the aid of the bridge navigating mark, mark display is not affected by sunlight reflection and lamplight transmission, the windward area is reduced, and the bridge navigating mark is good in wind resistance. A light source focuses the light intensity through a self-focusing collimating lens, and the scattering and the glaring of the light source can be greatly reduced. The light source controller can effectively control the light intensity and the flash cycle of the high-power LED lamp, so that the light intensity of a light-emitting body can be adjusted according to the observation distance, and the optimal displaying effect can be achieved. A groove is arranged on the outer wall of a cover body of the LED heat-dissipating device, so that the heat-dissipating area is increased, and the practicability is high.

Description

technical field

[0001] The invention relates to a sign, in particular to a bridge navigation aid sign. Background technique

[0002] With the rapid development of the country's economy and transportation, there are more and more bridges in my country's navigable waters, and the ships in the waterways are becoming more and more frequent. Previously, the position indication signs of the bridge's navigable bridge holes were not obvious, which led to the 2007 Guangdong Jiujiang Bridge ship accident. Serious accidents colliding with bridges, resulting in heavy loss of life and economy. For this reason, the national standard "Navigation Aids Marks for Bridges in Navigable Waters of China" was promulgated in September 2009 and implemented in February 2010. It is required that bridges in navigable waters must be equipped with navigation aids to ensure the safety of bridges and ships.

[0003] Navigation aids are generally set at sea or in the wild, and the environment is quite harsh...
