Heat dissipating device (10, 10') for an illuminating device (100), comprising a first bottom wall (1) and a first circumferential wall (2) configured to define a first cavity (3) opened at one side, the first bottom wall (1) is at least partially deformed to form a second bottom wall (4) and a second circumferential wall (5) that are configured to define a second cavity (6) opened at one side, and the first bottom wall (1), the first circumferential wall (2), the second bottom wall (4) and the second circumferential wall (5) are made in one piece from a metal sheet via a spinning or deep-drawing process. The heat dissipating device (10, 10') of the present invention has the advantages of a simple manufacturing process, a low cost, a light weight, capability of breaking through limits in size and section profile to some extent, and prominently improved heat dissipating ability. |
