Energy-efficient electronic light sources for marine vessels

Traditional marine lighting with low efficiency has been gradually replaced by high-efficiency electronic lighting equipment. However, these electronic lighting equipment are mainly for land use, and ignore unique lighting requirements of marine use, such as, temperature, vibration, etc. To confirm the applicability of land-use electronic light sources in a marine environment, several existing commercial electronic lamps are selected in this paper to replace traditional on-board light sources and then land and on-board tests are conducted according to maritime lighting regulations for comparison with traditional light sources in terms of performance. According to information in the test results, in response to the introduction of electronic lamps, existing ship lighting rules should be appropriately strengthened in terms of lighting and vibration test requirements. Meanwhile, general land-use electronic lamps should be strengthened with respect to vibration and lumens depreciation due to engine room environment. The analysis results can assist shipyards and ship owners in the selection of suitable electronic lamps, and can provide useful information to lighting equipment manufacturers for the development of lighting equipment that are suitable for electronic light sources for marine use.
