Enter inside in having prevented water from infiltering the first retaining ring 13.
In addition, passing through in the first connecting portion 21 of 16 bottom part of the first connector insertion step hole shape on lampshade 1
Stay bolt is connected and fixed lampshade 1 and substrate 2.
Lampshade 1 is made of the first lampshade 11 and the second lampshade 12, wherein the first lampshade 11 and the second lampshade 12 are using super
The mode that sound wave combines connects, and the second lampshade 12 is located at the outside of the first lampshade 11, and the interior surface of the second lampshade 12 also uses
Fresnel Lenses principle, the interior surface for using Fresnel Lenses principle to handle for 3 faces being contacted with the first lampshade 11, not with
The interior surface of first lampshade 11 contact is several arc convex, and the second lampshade 12 has the semicolumn of circle protrusion at bottom
Protrusion 15.
It is further described in conjunction with inside of the Fig. 4 to lampshade 1, Fig. 4 is the schematic bottom view of lampshade 1, it can be seen that lamp
There are the first connector 16 and the second connector 17 in cover 1, the effect of the first connector 16 is to connect with first connecting portion 21, the
Two connectors 17 can be stuck in second connecting portion 22, and the second connector 17 is in pairs at the two sides of the first connector 16, corresponding
Second connecting portion 22 is also in pairs at the two sides of first connecting portion 21, the specific location of second connecting portion 22 and first connecting portion 21
Relationship has been embodied in Fig. 1, and specific effect is that the first connector 16 is caught in first connecting portion 21, passes through bolt knot
Structure connection lampshade 1 and substrate 2, the second connector 17 are stuck in second connecting portion 22, pass through the hole from 22 bottom of second connecting portion
Screw is screwed in, lampshade 1 and substrate 2 are connected by screw to.
In addition, have in the second lampshade 12 semicolumn protrusion 15 and the first lampshade 11 and the second lampshade 12 not in contact with two
Side on a side (side herein refers exclusively to two sides herein, remaining face is interarea and top surface, and top surface is located at top) is convex
18 are played, lateral projections 18 are also semi-cylindrical in configuration, i.e., actually in the present embodiment, lateral projections 18 and semicolumn protrusion 15 are made
With identical, it is for preventing the light penetrated from its surface from light mixing occur.
Second lampshade 12 using Fresnel Lenses principle face be interarea and top surface, equally include positioned at middle part arc it is convex
It rises and several prisms is raised, it should be noted that prism protrusion is hung down in the prism protrusion of the second lampshade 12 and the first lampshade 11
Directly, including on the second lampshade 12 arc convex is also vertical with arc convex on the first lampshade 11.
Further, for the consistency of thickness inside lampshade, there is recess portion on the second lampshade 12 to accommodate the first lampshade 11, make
The inner thickness of entire lampshade is unified.
Referring to Fig. 5, the cross-section parts schematic diagram of one embodiment of the invention is shown, in order to illustrate to become apparent from, in Fig. 5
Section eliminates the structure of the second lampshade 12 and the internal structure of lampshade side, the position of the first connector 16 and the second connector 17
It sets as shown, cylindrical protrusions 15 are further illustrated in the position of lampshade 1 and degree of convexity, including the first lens 11 are right
The application of Fresnel Lenses principle, by taking top surface as an example, top surface interior surface be it is several it is triangular prism shaped at laciniation, with
And one section of circular arc at intermediate position.
Referring to Fig. 6, scheme of installation of the one embodiment of the invention with lamp source is shown, is installed additional in the figure for whole equipment
Lamp source 4, the LED lamp bead in lamp source 4 are illuminating part, on the fixed stud 41 on a substrate 2 of lamp source 4, second connecting portion 22 bottom
Portion is pierced by screw to connect the second connector 17 of lampshade 1.
In the present embodiment, the first lampshade 11 selects Transparent lamp shade, and the second lampshade 12 uses amber lampshade.
Further, the top surface long side of lampshade 1 has a radian, middle part (i.e. the first lampshade and the second lampshade knot of top surface
The position of conjunction) width maximum.
It is illustrated in conjunction with Fig. 1-6 pairs of entire embodiments, by taking clearance lamps of the present embodiment for vehicle as an example, lamp source 4 is sent out
Light out is mainly towards the top surface of lampshade 1 and two interareas, the better clearance lamps structure of illumination effect in order to obtain, lampshade 1
The light that interarea and top surface issue should be concentrated, the 3 faces actually principle contacted due to the first lampshade 11 and the second lampshade 12
It is identical, it is illustrated by taking top surface as an example.
Light on the first lampshade 11 of top surface is reached by by the first lampshade 11, according to Fresnel Lenses principle, by the
The light of one light shield 11 has carried out first concentration by the first light shield 11 by diverging indeed through a convex lens, light,
First lampshade 11 is actually to have concentrated across 11 top surface of lampshade and the light of 51 two sides of center line that is dispensed along in longitudinal direction
Line, collected in closer to 11 top surface of lampshade along the long side direction on center line 51.
Second lampshade 12 receives a part by the light of the first lampshade 11 and a part of light from light source, due to the second lamp
The prism protrusion inside 12 is covered perpendicular to the protrusion of the first lampshade 11, therefore the radiation direction that the second lampshade 12 collects is also perpendicularly to
First lampshade, the i.e. light across the second lampshade 12 have been concentrated across 12 top surface of lampshade and have been dispensed along the center line on short side direction
The light of 52 two sides is collected in the center line 52 closer to 12 top surface of lampshade on short side direction.
I.e. in the bond area of the first lampshade 11 and the second lampshade 12, light is more concentrated than the light of common lampshade,
It is stronger in thick fog weather and rainy day penetration power, also there is concentration appropriate in un-bonded area, common clearance lamps is possessed more preferably
Illumination effect.
The rest may be inferred, same principle, and the interarea of lampshade 1 and top surface possess identical effect.
For being located at lateral projections 18 of the lampshade 1 in the semicolumn protrusion 15 and lampshade 1 of bottom, across its light
It will uniformly be precipitated, and avoid and situations such as light mixing occur.
When first connecting portion 21, second connecting portion 22 and opening 23 are attached, in order to guarantee leakproofness, generally adopt
It is sealed with sealing ring.
It is to be illustrated to what preferable implementation of the invention carried out, but the invention is not limited to the implementation above
Example, those skilled in the art can also make various equivalent variations on the premise of without prejudice to spirit of the invention or replace
It changes, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
