Fig. 3 is the explosive view of the utility model embodiment.
Specific embodiment
As shown in Figure 1-Figure 3, the utility model provides a kind of LED vehicle-mounted illuminating lamp, include outer cover 1 and be equipped with outer cover 1
Interior pcb board 2, the pcb board 2 are equipped at least two LED lamp beads 3, and the outer cover 1 is towards setting on the end face of pcb board 2
Have a cavity 21, be equipped in the cavity 21 lens 4 corresponding with 3 quantity of LED lamp bead, the lens 4 and 1 one of outer cover at
Type, the lens 4 are equipped with accommodating chamber 41 corresponding with LED lamp bead 3, institute towards one end of pcb board 2 in cone, lens 4
The lens 4 stated are in the spherical surface 42 that the end face in accommodating chamber 41 is in outwardly convex, and 1 outer surface of outer cover is corresponding with spherical surface
Face is the second spherical surface 43 of outwardly convex, and the corresponding position of 1 outer surface of outer cover and each lens 4 is respectively along the second spherical surface 42
Equipped at least two spreading grooves 44, spreading grooves 44 are annularly wound on 43 outside of the second spherical surface, and innermost 44 diameter of spreading grooves is big
In the diameter of the second spherical surface 43, step is formed with the second spherical surface 43, multiple 44 diameters of spreading grooves are gradually increased, and mutually form platform
Rank, the stepped setting of spreading grooves 44.Corresponding 1 outer surface of outer cover of each lens 4 is arranged most along the second spherical surface 43
The outermost spreading grooves 44 of external spreading grooves 44 and adjacent lens 4 are connected.In above scheme, due in 1 outer surface of outer cover
Multiple spreading grooves 44 are equipped with along the second spherical surface 43 with the corresponding position of lens 4, after the light of LED lamp bead 3 passes through 41 optically focused of accommodating chamber,
The diffusion of spreading grooves 44 is increasingly towards by the second spherical surface 43 again, due to the mutual stepped setting of multiple spreading grooves 44, light
