Abstract

PURPOSE: To prevent the reduction of a horizontal incidence range of an all-round lamp by upper structures, such as, a mast, etc., by multually arrangeing the light sources of the all-round lamp at an interval, and by mutually disposing two dousers between the light sources at an interval.
CONSTITUTION: Each light soruce 1 is mounted to the outside of an approximate central location of a douser 3, and both dousers 3 are mutually connected by means of a strut 4. A horizontal incidence range of lights emitted from light sources 1 is shown as in the figure, and the hocizontal insidence range of the light source 1 is hardly prevented even if there are upper structures 6, shuch as, a mast, etc. at the stern direction Y side. That is, a range B, which cannot perfectly be confirmed by eyes, remarkably becomes small, a range C, in which both light sources 1 can simultaneously be viewed, is formed in the stern direction Y of a location D where the focusing of the range B is completed, but two light sources 1 cannot simultaneously be viewed normally even if viewing from the range C becuase there is sufficient distance.
