Preferably, the fixed installation nut is provided with eight altogether, and eight fixed installation nuts are uniformly arranged on lens
On mounting flange.
Preferably, the V-groove is at least provided with ten, and ten V-grooves are uniformly installed in the interposition of compound curved surface
Put place.
Preferably, the cone tank is at least provided with ten, and ten cone tanks are uniformly installed in the left and right of compound curved surface
Two ends.
Compared with prior art, the beneficial effects of the utility model are：This utility model is scientific and reasonable for structure, using safety
Convenient, the lens mounting flange on the lens of the street lamp is easy to use, and facilitates the compound type groove of the installation of lens, street lamp to be easy to lamp
Light irradiation scope, it is to avoid the not enough problem of light luminance, the arcuate structure of bottom enhances spotlight effect, while double layer lens
The spotlight effect of street lamp is further enhanced, long service life, light type effect are good, good water-proof effect, it is to avoid overcast and rainy steam
Enter.
