A high-power LED lamp, including: a shell, a light-emitting assembly, heat dissipating fins, the light-emitting assembly includes a reflective bowl, a LED and a lens, characterized in that, the heat dissipating fins are radially installed in the channel of the shell, the outer end of each heat dissipating fins is connected with the inner wall of the shell, with the inner end linked to the outer wall of a circular cylinder, all of the front end faces of the heat dissipating fins form a cone-shaped concave torus, the reflective bowl is provided on the cone-shaped concave torus; the axis of the circular cylinder coincides with the axis of the shell, the front end face of the circular cylinder is planar, and the LED and the lens are installed on the surface. Compared with the prior art, the radially fenced-shaped heat-dissipating fins communicating from the front to the rear are provided in the shell, which will be more conducive to the air ventilation around the heat-dissipating fins, as well as heat transfer, and remove the heat generated by the LED nodes in time to improve the effect of heat dissipation. |
