摘要:
The present invention relates to an ice-making assembly for a refrigerator and a refrigerator including the same. According to the present invention, a freezing chamber door is provided with an ice-making assembly, and ice made by the ice-making assembly can be immediately drawn out to the outside by opening an exclusively used home-bar door. In addition, an ice-making case is coupled by a coupling means formed integrally with the freezing chamber door and the ice-making case without a coupling tool or operation. Moreover, according to the present invention, if a water bucket is installed to the ice-making case, a water supply hole of the lower end of the water bucket is opened by an opening and closing means, so that water in water bucket is automatically supplied to an ice tray. In addition, an ice-separating lever having a ‘⊂’ shape is provided to simultaneously rotating a plurality of ice trays. Meanwhile, in the present invention, an ice bank cooperates with the home-bar door to be drawn out forward as the home-bar door is opened. According to the present invention, the use convenience of a refrigerator is improved.

Disclosed herein is a package structure including at least one high power light-emitting diode to exhibit excellent heat release properties. In the package structure, a light-emitting diode chip which generates heat is directly attached to a beacon processed to protrude from part of a heat spreader having high heat conductivity, whereby an electrical wiring portion is separated from a heat release portion, thus maximizing heat release properties and realizing high luminance and reliability. The package structure is composed of a beacon formed on a metal or non-metal substrate having high heat conductivity to mount a high power light-emitting diode chip, to increase heat release properties; a wiring portion provided on the same line as the diode to input and output power and signals; and a reflection cup having a cavity, which may be inserted into or attached to the heat spreader or the wiring substrate, including a low temperature co-fired ceramic substrate, a high temperature co-fired ceramic substrate, or a printed circuit board.

Disclosed is a method of attaching an optical waveguide component to a printed circuit board, which is a double-sided or a multilayer printed circuit board, through pre-bonding and main-bonding by use of an adhesive tape. Prior to being attached to the printed circuit board, the optical waveguide component is preferably subjected to a plasma surface treatment to give a surface roughness thereto. The present method is advantageous in that the optical waveguide component can be attached to the printed circuit board with improved flatness and precise alignment without causing chemical or thermal damage to the optical waveguide component.

Disclosed is a printed circuit board with opto-via holes for transmitting an optical signal to an optical waveguide in the PCB, and a process of forming the opto-via holes. The process comprises forming a plurality of via holes on a plurality of copper clad laminates using a drill, plating an inner wall of each via hole, exposing and etching the plated portions of an upper and lower side of each copper clad laminate to form a circuit pattern on the upper and lower side of the copper clad laminate, layering the patterned copper clad laminates on each other using an insulating resin adhesive, and removing the insulating resin adhesive in the predetermined via holes to form opto-via holes. Therefore, the process is advantageous in that the optical signal is stably transmitted to the optical waveguide in the PCB without damage to the optical waveguide directly exposed to an external environment, and the optical waveguide suitable to physical properties of the material constituting the PCB is easily inserted between the inner layer and the outer layer.
