Abstract: A package structure and a method of forming the same are provided. The package structure includes a first die, a second die, a first encapsulant, and a buffer layer. The first die and the second die are disposed side by side. The first encapsulant encapsulates the first die and the second die. The second die includes a die stack encapsulated by a second encapsulant encapsulating a die stack. The buffer layer is disposed between the first encapsulant and the second encapsulant and covers at least a sidewall of the second die and disposed between the first encapsulant and the second encapsulant. The buffer layer has a Young's modulus less than a Young's modulus of the first encapsulant and a Young's modulus of the second encapsulant.

Abstract: A fluid-convection heat dissipation device includes at least one heat dissipation module, at least two baffles, and a heat dissipation fluid. The heat dissipation module forms at least one internal receiving space and has an outside surface to which at least one light emission element is attached. The baffles are arranged in the receiving space to divide the receiving space into a plurality of convection channels that are in fluid communication with each other. The heat dissipation fluid is received in the receiving space as a convection medium displaceable in a circulating path along the plurality of convection channels.

Abstract: Disclosed is a light guide device for a water spraying device. The light guide device includes a light guide block that is a light-transmitting block having a refractive index greater than one. The light guide block has a circumferential face in which a plurality of mounting holes is defined for receiving and retaining light-emitting elements. A plurality of through holes is defined through the light guide blocks and extends in a direction substantially perpendicular to the mounting holes. Each through hole has a roughened inside surface. The through holes are in fluid communication with water discharge holes of the water spraying device so that water jets supplied from the water spraying device can flow through the through holes for discharging. The light-emitting elements emit light rays that transmit through the light guide block and get into the through holes and the water jets. The rays are subject to reflection inside the water jets to provide lighting or luminous effect to the water jets.
