LED light source boards 2 are inserted into one end of each fixing slot 11 and secured within it by protrusions at the top of the slots. In this embodiment, three fixing slots 11 are provided, and the number of LED light source boards 2 can be selected according to requirements, preferably in a symmetrical arrangement. Multiple heat dissipation fins 12 are centrally located on the lower side of the heat sink 1. These fins are directly opposite the fixing slots 11, reducing the heat transfer distance and improving heat dissipation efficiency. The controller for the LED light source boards 2 is fixed to the lower side of the heat sink 1.

[0033] The lampshade 3 covers the LED light source board 2. The lampshade 3 has an open structure with a semi-elongated hole in cross-section, and both sides of the lampshade 3 have folded edges.
