The specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing.
See accompanying drawing 1-9, the present invention includes a plurality of lens monomers 10, lens monomer 10 adopts light transmissive material to make, the bottom surface e undulate of lens monomer 10, and lens monomer 10 offers the LED standing groove, and as shown in FIG., the lateral length of LED standing groove is greater than longitudinal length; The bottom surface e of described lens monomer 10 is made of the aspheric surface arc surface.
Described lens monomer 10 comprises four sides, forward and backward two sides g undulate, and these two sides g is made of the aspheric surface arc surface.
The bottom surface d undulate of described LED standing groove, this bottom surface d is made of the aspheric surface arc surface.
Described LED standing groove is small in ends, broad in the middle, and it comprises four sides, forward and backward two sides f undulate, and these two sides f is made of the aspheric surface arc surface, and as shown in Figure 9, these two sides f is formed by connecting by two sections aspheric surface arc surface f1, f2 respectively.
The bottom surface e shape dislocation of the bottom surface d shape of described LED standing groove and lens monomer 10, as shown in Figure 8, for a lens monomer 10, upward convex surface, one section concave surface constitute this bottom surface d by two sections, corresponding, the bottom surface e of lens monomer 10 is made of two sections following convex surfaces, one section upper recess surface.
The forward and backward two sides f shape dislocation of the forward and backward two sides g shape of described lens monomer 10 and LED standing groove, as shown in Figure 1, 2, for a lens monomer 10, upward convex surface, one section concave surface constitute the forward and backward two sides g of this lens monomer 10 by two sections, corresponding, the forward and backward two sides f of LED standing groove is made of two sections following convex surfaces, one section upper recess surface.
The upper surface area of described lens monomer 10 is less than the area of the bottom surface e of lens monomer 10, and four sides of described lens monomer 10 are not vertical, and lens monomer 10 is terrace with edge shape substantially.
The and arranged on left and right sides face c of described lens monomer 10 is inner concavity, and these two sides c is made of the aspheric surface arc surface.
Described a plurality of lens monomer 10 is array and distributes, and the bottom surface e of lens monomer 10 extends the bottom surface that is connected to form lens integral body, and the bottom surface e shape of the coupling part of each lens monomer 10 is undulate also, as shown in Figure 2.
The described lens integral body outside has to install encloses frame 20, encloses to offer pilot hole a on the frame 20, and pilot hole a further guarantees the convenience and the flexibility of assembling, and effectively satisfies the matching requirements of different electronic circuit boards; Enclose and form reference column b on the frame 20, reference column b more can guarantee the convenience and the stability of assembling, and efficiently solves the phenomenon of rigging position dislocation.
Aspheric surface arc surface structure is adopted in many places of the present invention, and their concrete principle has following several:
One, the function of the forward and backward two sides g of described lens monomer 10: these two sides g is a fully reflecting surface, the purpose of its design is that the light of LED high power light source at this side is all reflected, change the direction and the density of this part light, the mode that needs according to design all directly penetrates from the bottom surface e of lens, thereby arrives the target of setting;
Two, the function of the bottom surface d of described LED standing groove: this bottom surface d is that the master advances the light face, all light that comprise on the forward and backward two sides g direction of LED high power light source front light and lens monomer 10 enter lens by this bottom surface d, and direction and density to light in the process that light enters are carried out the arrangement of first;
Three, the function of the bottom surface e of described lens monomer 10: this bottom surface e is the lens exiting surface, all light face ejaculation thus enter in the air, its effect is that density and the angle of light on the g direction of the forward and backward two sides of lens monomer 10 of all outgoing adjusted, and makes it can satisfy road surface scope and inhomogeneity requirement;
Four, before the described LED standing groove, the function of back two sides f: before this, back two sides f is, left side at lens monomer 10 of sending by the LED high power light source, what the light of right two sides c direction entered lens advances the light face, effect is that the direction of this part light and density are carried out preliminary adjustment, before this part light is by described lens monomer 10, when back two sides g arrives the bottom surface e of described lens monomer 10, the light of the bottom surface e of the regular basic and bottom surface d arrival lens monomer 10 that passes through the LED standing groove of light angle and density is close, makes things convenient for the adjustment of the bottom surface e of lens monomer 10 to all light;
The and arranged on left and right sides face c of described lens monomer 10 also can be a fully reflecting surface, to improve the radiation response of light.
The present invention adopts the collection modules design, considering that carrying out intensive modularization after LED high power light source arrangement position and heat radiation require arranges, has saved the device mounting space greatly, and convenient simultaneously the installation is when saving the assembler;
But the present invention's fitted seal circle is to realize water-proofing treatment.
Certainly, the embodiment of the above is a preferred embodiments of the present invention, is not to limit the scope of the present invention, so all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify, and all should be included in the present patent application claim.
