Technical Field
The invention relates to the field of beacon lights, in particular to a hemispherical angle-expanding lens.
Background
The navigation mark lamp is one kind of aviation obstruction lamp series product and is one kind of traffic lamp installed on some navigation mark to ensure the safe navigation of ship at night. The navigation mark lamp series products are respectively provided with 4 types of fixed lamp marks, lamp buoys, light boats and lighthouses, and are required to emit specified light colors and flash frequencies at night to reach specified irradiation angles and visible distances.
Because the LED lamp has many advantages of low energy consumption, the LED lamp is generally adopted as the light source of the indicating navigation mark lamp in the existing navigation mark lamp, but the LED lamp also has the defect that the irradiation angle of the LED lamp is generally about 120 degrees at most, and therefore in order to solve the problem of the irradiation angle, various lenses are used for increasing the irradiation angle of the LED lamp.
The current lens mainly adopts the following forms, namely a planar Fresnel lens, and the main use places of the planar Fresnel lens are a navigation mark lamp, a bridge mark lamp and the like; secondly, the planar lattice convex lens is also used for a guide lamp and a bridge lamp in the navigation mark lamp; the drum-shaped prism lens is used for splitting light by using a prism, and a drum-shaped structure changes a point light source into parallel light to improve the range, so that the drum-shaped prism lens is widely used in navigation mark lamps in sea areas; and fourthly, the Fresnel lens is widely applied to the inland navigation mark lamp. The fresnel lens has the function of elongating light in the vertical direction and changing a point light source into a parallel light source in the horizontal direction. Therefore, in the navigation light using the drum-type prism lens, the light source is generally made into a multi-layer light source structure, and the drum-type prism lens is correspondingly made into a plurality of drum-types to be used in series.
However, the illumination angle of the existing lens still has a large blind area, and therefore how to increase the illumination angle of the lens becomes a problem to be solved urgently by those skilled in the art.
