Inner arc reflective surface, the lens be equipped with outwardly directed annular step surface, the bottom case be equipped with faced with the ring-shaped step
The groove answered, the lens are embedded in bottom case by the cooperation of annular step surface and groove, are set in the middle part of the diffusing reflection outer cover
There is the connecting column extended downwardly, connection through-hole corresponding with the connecting column, the bottom case are equipped on the lens and pcb board
Equipped with link slot corresponding with connection through-hole, the connecting column passes through through-hole and connect with the link slot, by diffusing reflection outer cover, thoroughly
Mirror, pcb board and bottom case link together.
In above description, preferably, the lens and bottom case diameter are all larger than pcb board diameter, the lens are equipped with and open
The downward optics of lens slot of mouth, and the LED lamp bead is wrapped in optics of lens slot.
In above description, preferably, the connecting column is detachably arranged in the middle part of diffusing reflection outer cover by screw.
In above description, preferably, the two sides of the diffusing reflection outer cover are equipped with spring ear.
In above description, preferably, the bottom case is equipped with the radiating surface for heat dissipation.
Beneficial effect caused by the utility model is: lens, table on pcb board are equipped between diffusing reflection outer cover and pcb board
Face is equipped with multiple LED lamp beads, and the light of LED lamp bead penetrates the inner arc reflective surface of lens directive diffusing reflection outer cover, and light first passes through
Lens deflect, then light is shone on the ground by inner arc reflective surface, keep product uniform illumination soft.
For structure feature, technological means and its specific purposes achieved and function for more clearly illustrating the utility model
Can, the utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
