, the groove or it is raised be frosting, the light distribution structure 20 is used to inject the light-guiding pillar towards the outer refractive of guide-lighting cylinder 10
Light in body 10, so, the light got on lines is transmitted from lens surface, and other light are propagated along aforesaid paths.Or
Person, specifically, the groove or projection are covered with reflecting layer, and light distribution structure 20 is used for the internal reflection light of the guide-lighting cylinder 10 of direction simultaneously
Make light be ultimately towards the outside of guide-lighting cylinder 10 Jing after the medial wall of guide-lighting cylinder 10 or roof or lateral wall refraction to project.It is logical
Above-mentioned setting is crossed, the propagation path for injecting the 10 inside light splitter of guide-lighting cylinder can be changed, totally apparently, due to by the lines
The light intensity projected after luminous intensity distribution is higher, therefore visually apparently overall effect of lighting just looks like that the tungsten filament in conventional incandescent is being sent out
Light, so as to visually simulate the illumination effect of electric filament lamp.In fact, the lines can be arranged as required to into other shapes, with
Different illumination effects are presented, conventional incandescent is not limited only to.
Additionally, the bottom of light-distribution lens 1 can also be provided with installation portion 30, in order to light-distribution lens are arranged on light source assembly etc.
In other assemblies.Installation portion 30 can be the connecting portion or clamping part worn for trip bolt.With reference to Fig. 1, in the present embodiment, peace
Dress portion 30 is the connecting portion worn for trip bolt.
Additionally, guide-lighting cylinder 10 can be easily-controllable by integrated through injection molding chemical conversion type, process is simple.The material for using is transparent material
Material, such as glass, polymethyl methacrylate, Merlon, epoxy resin, polyethylene terephthalate etc..With reference to Fig. 3,
In another embodiment, unlike the embodiments above, light distribution structure 20 ' is disposed on the lateral wall of guide-lighting cylinder 10, top
Lines is equipped with lines on wall, the wherein upper surface 131 and the lower surface 132, lines can also be groove or projection
Structure, and the groove or raised be frosting or be covered with reflecting layer.Lines also has conventional incandescent tungsten filament shape white to simulate
Vehement lamp illumination effect.
In another embodiment, with reference to Fig. 4 to Fig. 5, and unlike first embodiment, the lower surface of light out part 13 '
132 ' be by multiple arcs face along guide-lighting cylinder 10 ' the bowl-shape wall of many ribs that surrounds of circumference, the top perimeter shape of light out part 13 '
Into polygon, preferably regular polygon.The periphery wall of guide-lighting cylinder 10 ' is at least a partially formed and 13 ' lower surface of light out part
132 ' the polygon prism shape walls for coordinating.Illustrate by taking hexagon as an example below, with reference to Fig. 4, light is in 13 ' Jing upper tables of light out part
When face 131 ' occurs total reflection and reflects, as lower surface 132 ' (exiting surface) is divided into 6 faces, and output optical zone domain concentrates on
The hexagonal area at top, when lighting, naked eyes are apparently presented the effect of hexagon aperture, closer to the luminous sensation of tradition tungsten filament,
So as to visually simulate the illumination effect of electric filament lamp.Additionally, can also be pentagon or other polygonal forms.
With reference to Fig. 6 to Fig. 7, the LED of one embodiment of this utility model, including the light-distribution lens 1, lamp of an above-mentioned embodiment
2, lamp body 3, light source board 4 and bulb housing 5.Lamp body 3 is assemblied on lamp holder 2, and bulb housing 5 is assembled to form a cavity volume, light with lamp body 3
Source plate 4 and light-distribution lens 1 are arranged in cavity volume.Wherein light source board 4 is located at the top of lamp holder 3, the light in part and light source of light-distribution lens 1
Plate 4 is relative, and the light that light source board 4 sends outwards is reflected by the light-distribution lens, so as to electric filament lamp illumination effect is presented.
Some LED lamp beads 41 of circumferential arrangement are provided with light source board 4, the annular light in part 12 pairs of light-distribution lens 1 should
LED lamp bead circle.During energization, LED lamp bead 41 lights, light from the light in part 12 of 10 bottom of guide-lighting cylinder enter guide-lighting cylinder 10 and to
Upper conduction.There is diffuse-reflectance when getting on tungsten filament shape lines in light, and get from lens surface, and remaining light is passed to light out part 13
Lead, being partly all-trans by 131 part of upper surface is incident upon lower surface 132 and reflects away, part is directly saturating by upper surface 131
Penetrate.Tungsten filament shape lines is stronger to the light of external reflectance, so as to see the illumination effect that electric filament lamp is presented on the whole.Simultaneously because upper table
The reflection in face 131 realizes the luminous intensity distribution of wide-angle, and distribution curve flux is uniform.Light-distribution lens 1 are assemblied in bulb housing 5, bulb
