[0002] Navigational signal lights include port and starboard lights, masthead lights, stern lights, towing lights, all-around lights, and flashing lights. These lights are used on all types of ships for nighttime navigational signaling and communication. Traditional navigational signal lights utilize an incandescent lamp with a Fresnel lampshade and a sunshade. Due to the difficulty in controlling the size of the filament, this design fails to meet the optical requirements of navigational signaling standards. Furthermore, traditional navigational signal lights can only operate at -25°C, where ice can form on the lampshade, severely impacting the optical quality and signaling. Furthermore, existing navigational signal lights lack robust connections and poor sealing, making them susceptible to damage in extreme weather conditions.
[0003] In order to solve the deficiencies in the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a high-hardness coating applied to the surface of SMC and BMC [CN201910242310.7], which includes a base, a mounting base, an LED driver power supply, a thermostat, a heater, a radiator, an LED light source, a lens, a lampshade and an upper cover, wherein the mounting base is mounted on the base, the LED driver power supply, the thermostat and the heater are all arranged on the mounting base, the heater is electrically connected to the thermostat, the radiator is arranged above the LED driver power supply, the thermostat and the heater, the LED light source is arranged on the side wall of the radiator, the lens cover is arranged on the LED light source, the lampshade is sleeved on the outside of the radiator, and the upper cover is arranged on the lampshade.

However, the solution still has many shortcomings, such as insufficient connection stability and poor sealing, and is prone to damage when encountering special weather at sea.
