An LED waterproof diffuser has an LED substrate housing, a diffusing portion and an embedded locating portion. The housing is of a 3D holding space formed by an end wall and a periphery. An LED inlet is formed at the other end of the periphery. The hollow diffusing portion is protruded from the center of the end wall of the LED substrate housing in a reducing pattern. The embedded locating portion is formed externally onto the diffusing portion, and can also be embedded securely into the hole of an existing shell plate. The diffuser allows one to assemble a single or several LED units, thus reducing the manufacturing cost and realizing excellent waterproofing effects, while enabling partial replacement or maintenance of LED elements. Moreover, since the outer diameter of the diffusing portion is smaller than that of the LED substrate housing, a smaller hole area for assembly can be obtained. |
