Abstract
The utility model discloses a kind of navigation light light emission lens, it is characterized in that it comprises the beam that is all-trans (3), 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), inside surface is obconic pointed cone structural plane (4), pointed cone structural plane (4) is provided with equally distributed annular dimpling lens (6), the utility model is energy-conservation, system bulk is less, and luminous intensity distribution is even, and capacity usage ratio is high, cost is low, makes navigation mark modulator good working effect.
Description
Technical field:
The utility model relates to a kind of navigation light light emission lens, belongs 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 comparatively large, and the light source power consumption matched is comparatively large, and the use of multiple LED also causes light distribution uneven, both adds cost of products, also makes the effect of navigation mark modulator work poor.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of energy-conservation, and 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.
The purpose of this utility model can be reached by following measure: a kind of navigation light light emission lens, 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 be provided with lens bottom outlet in the lower end of the beam that is all-trans, 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 to realize the purpose of this utility model further, in the lower end of the described beam that is all-trans has, establish the installation fixed station of lens bottom outlet.
The utility model can produce following good effect compared with the prior art: in order to enable light with certain vertical divergence angle and horizontal 360-degree from lens profile horizontal exit, single LEDs light source is placed in lens bottom outlet 1 of the present utility model by the utility model, utilize light to enter optically thinner medium from optically denser medium and can produce total reflection principle, make to penetrate from lens profile through total reflection at lens interior from the light of lens bottom outlet 1 incidence.Its basic process is: first the light of LED light source reflect on the bottom outlet face of cylinder 2, arrive the free form surface 9 of the beam 3 that is all-trans, reflection through free form surface 9 arrives pointed cone structural plane 4, pointed cone structural plane 4 there are dimpling lens 6, it act as the light after by collimation by certain mixed reflection, outgoing light belt be evenly distributed, last light belt reflects lens by the face of cylinder 5 outside cylindrical reflector 8, reaches predetermined shooting angle.Therefore the utility model has the higher efficiency of light energy utilization, luminous intensity distribution is even, optimize system architecture, reduce 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.
Accompanying drawing illustrates:
Fig. 1 is cut-open view of the present utility model;
Fig. 2 is light path schematic diagram of the present utility model.
Embodiment: embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of navigation light light emission lens (see Fig. 1-Fig. 2), it comprises the beam 3 that is all-trans, and 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 and installs fixed station 7, 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.
During use, LED light source is placed in lens bottom outlet 1, LED hood is lived to prevent external interference by this design.Light is refracted into lens from lens bottom outlet 1, arrive the free form surface 9 of the beam 3 that is all-trans, pointed cone structural plane 4 is reflexed to through free form surface 9, pointed cone structural plane 4 there are dimpling lens 6, it act as the light of collimation by certain mixed reflection, outgoing light belt be evenly distributed, the face of cylinder 5 eventually passed outside cylindrical reflector 8 reflects lens, 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).
