Abstract
The invention discloses a light-emitting lens for a beacon light. The light-emitting lens for the beacon light is characterized by comprising a total reflection body (3), and the outer surface of the total reflection body (3) is a free-form surface (9); a cylinder reflection body (8) is arranged at the upper end of the total reflection body (3), the total reflection body (3) and the cylinder reflection body (8) are integrally connected, a bottom lens hole (1) is formed in the lower end of the total reflection body (3), and the inner surface of the bottom lens hole (1) is a bottom hole cylindrical surface (2); the outer surface of the cylinder reflection body (8) is a cylindrical surface (5), the inner surface of the cylinder reflection body (8) is a reversed conical pointed cone structural surface (4), and annular micro convex lenses (6) are evenly distributed on the pointed cone structural surface (4). The light-emitting lens for the beacon light is capable of saving energy, small in system size, even in light distribution, high in energy utilization rate, low in cost and good in work effect of the beacon light.
Description
Technical field:
The present invention relates to a kind of navigation light light emission lens, belong to navigation mark technical field.
Background technology:
At present, the optical design of traditional navigation mark modulator, light source is generally multiple LED circular array horizontal positioned in the plane, and each LED pipe is vertical with lens cylinder.This kind of lens volume is larger, and the light source power consumption matching is larger, and the use of multiple LED also causes light distribution inhomogeneous, has both increased cost of products, also makes the effect of navigation mark modulator work poor.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of energy-conservation, system bulk is less, and luminous intensity distribution is even, and capacity usage ratio is high, and cost is low, makes the navigation light light emission lens of navigation mark modulator good working effect.
Object of the present invention can reach by following measure: a kind of navigation light light emission lens, it is characterized in that it comprises the beam that is all-trans, and the outside surface of the beam that is all-trans is free form surface; The be all-trans upper end of beam is provided with cylindrical reflector, and be all-trans beam and cylindrical reflector are connected as a single entity, and are provided with lens bottom outlet in the lower end of the beam that is all-trans, and lens bottom outlet inside surface is the bottom outlet face of cylinder; The outside surface of cylindrical reflector is the face of cylinder, and inside surface is obconic pointed cone structural plane, and pointed cone structural plane is provided with equally distributed annular dimpling lens.
In order further to realize object of the present invention, in having, the lower end of the described beam that is all-trans establishes the installation fixed station of lens bottom outlet.
The present invention can produce following good effect compared with the prior art: in order to make the light can be with certain vertical divergence angle and horizontal 360-degree from the horizontal outgoing in lens side, single LEDs light source is placed in lens bottom outlet 1 of the present invention by the present invention, utilize light to enter optically thinner medium from optically denser medium and can produce total reflection principle, make to penetrate from lens side in the total reflection of the inner process of lens from the light of lens bottom outlet 1 incident.Its basic process is: first the light of LED light source reflect on the bottom outlet face of cylinder 2, the be all-trans free form surface 9 of beam 3 of arrival, reflection through free form surface 9 arrives pointed cone structural plane 4, on pointed cone structural plane 4, there are dimpling lens 6, it act as the light after collimation by certain mixed reflection, light belt being evenly distributed of outgoing, last light belt reflects lens by the face of cylinder 5 in cylindrical reflector 8 outsides, reaches predetermined shooting angle.Therefore the present invention has the higher efficiency of light energy utilization, luminous intensity distribution is even, optimize system architecture, reduced system bulk, can reach different light intensity demand according to service condition, lens mate with single LEDs, greatly reduce the power consumption of modulator, capacity usage ratio is high, and cost is low, makes navigation mark modulator working effect better.
Brief description of the drawings:
Fig. 1 is cut-open view of the present invention;
Fig. 2 is light path schematic diagram of the present invention.
Embodiment: the specific embodiment of the present invention is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of light emission lens (referring to Fig. 1-Fig. 2) for navigation light, it comprises the beam 3 that is all-trans, the outside surface of the beam 3 that is all-trans is free form surface 9; The be all-trans lower end of beam 3 is provided with fixed station 7 is installed, upper end is provided with cylindrical reflector 8, be all-trans beam 3, fixed station 7 and cylindrical reflector 8 be installed be connected as a single entity, the lower end of the beam 3 that is all-trans and install in fixed station 7 and be provided with lens bottom outlet 1, lens bottom outlet 1 inside surface is the bottom outlet face of cylinder 2; The outside surface of cylindrical reflector 8 is the face of cylinder 5, and inside surface is obconic pointed cone structural plane 4, and pointed cone structural plane 4 is provided with equally distributed annular dimpling lens 6.
When use, LED light source is placed in to lens bottom outlet 1, this design covers to prevent external interference by LED.Light is refracted into lens from lens bottom outlet 1, the be all-trans free form surface 9 of beam 3 of arrival, reflex to pointed cone structural plane 4 through free form surface 9, on pointed cone structural plane 4, there are dimpling lens 6, it act as the light of collimation by certain mixed reflection, light belt being evenly distributed of outgoing, reflects lens finally by the face of cylinder 5 of crossing cylindrical reflector 8 outsides, reaches predetermined shooting angle.
Claims (2)
1. a navigation light light emission lens, is characterized in that it comprises the beam that is all-trans (3), and the outside surface of the beam that is all-trans (3) is free form surface (9); The be all-trans upper end of beam (3) is provided with cylindrical reflector (8), and the beam that is all-trans (3) and cylindrical reflector (8) are connected as a single entity, and are provided with lens bottom outlet (1) in the lower end of the beam that is all-trans (3), and lens bottom outlet (1) inside surface is the bottom outlet face of cylinder (2); The outside surface of cylindrical reflector (8) is the face of cylinder (5), and inside surface is obconic pointed cone structural plane (4), and pointed cone structural plane (4) is provided with equally distributed annular dimpling lens (6).
