[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0024] Such as figure 1 , figure 2 As shown, the bridge navigation aid sign includes a sign body 1 and a light-emitting component 2 provided on the surface of the sign body 1. The sign body 1 includes a frame body 11 and a plurality of mutually parallel wind deflectors 12 arranged in the frame body 11. The wind deflectors 12 form a certain angle with the horizontal plane, and the angle is less than 90° . The light-emitting component 2 includes an aluminum-based circuit board 21, an LED heat sink 24 arranged on the aluminum-based circuit board 21, a high-power LED lamp 22 packaged in the LED heat sink 24, and used to control the large The light source controller 23 of the power LED lamp 22 light intensity and flash cycle.
[0025] The aluminum-based circuit board ...
