Abstract: A wavelength conversion element includes a base plate and a rotating device. The base plate has a first surface and a second surface. The first surface is configured to allow a fluorescent layer to dispose on. The base plate includes some first grooves and some second grooves. The first grooves are disposed on the first surface around a center of the base plate. The second grooves are disposed on the second surface around the center. The first grooves and the second grooves are staggered from each other along a rotating direction. The base plate has some through holes. Each of the through holes communicates with the second surface and the corresponding first groove. The rotating device is connected with the base plate and configured to drive the base plate to rotate about an axis along the rotating direction. The axis passes through the center.

Abstract: A heat dissipation assembly is disclosed and includes a fan, a vapor chamber and a heat dissipation fin set. The fan includes a fan frame, an impeller and a fan cover. The impeller is disposed on the fan frame and accommodated in an accommodation space. The impeller includes plural metal blades and a hub, and the plural metal blades are radially arranged on the periphery of the hub to form a dense-metal-blade impeller. The fan cover is assembled with the fan frame to form an outlet, and the fan cover includes an inlet. The vapor chamber includes an upper plate and a lower plate assembled with each other. The upper plate or the lower plate is connected to the fan cover, and the vapor chamber and the fan cover are coplanar. The heat dissipation fin set is connected to the lower plate and spatially corresponding to the outlet.
