Description

Technical Field

[0001] This utility model relates to the field of navigation light technology, and in particular to a high-power navigation light device. Background Technology

[0002] Navigation lights are needed to indicate the location, direction, and potential hazards of navigation channels for ships at night or in adverse weather conditions. Early navigation lights used incandescent and neon lamps, which suffered from problems such as easy damage, short lifespan, high power consumption, insufficient brightness, and inadequate visibility, affecting navigational aids and safety. High-power, high-brightness LED lights have higher luminous efficiency, significantly lower energy consumption, and a longer effective visibility range, directly improving the warning and guidance effects of navigation lights.

[0003] The International Association of Lighthouse Authorities (IALA) and national maritime authorities (such as the China Maritime Safety Administration) set mandatory or recommended requirements for the rated beam range of navigation lights based on the hazard level of the route, vessel traffic density, and local geographical conditions. Especially in open seas, at port entrances, and major turning points, beacon towers, as critical navigational aids, must meet or exceed these requirements for their lighting performance.

[0004] For navigational beacons, long-range navigation lights are not an "optional upgrade," but rather an "essential attribute" for fulfilling their core navigational aid functions. This demand drives navigation light technology towards higher luminous efficiency, smarter control, more reliable operation, and greater energy efficiency. Selecting and applying long-range navigation lights is a systematic decision that comprehensively considers navigation safety regulations, geographical environment, technical feasibility, and total life-cycle costs.

[0005] The Ministry of Transport has also approved and released the "Measurement of Light Intensity and Calculation of Light Range for Navigation Lights" (JT / T 730-2023), which focuses on precise optical measurements to ensure that the "navigation" performance of navigation lights is based on reliable standards. Meanwhile, the "General Technical Conditions for Navigation Lights" (JT / T 761-2022) is a more comprehensive product standard that sets forth general technical requirements for all aspects of navigation light design, production, and acceptance.
