摘要： The present invention provides a heat conducting slug having a multi-step structure, which is installed to an LED package to dissipate heat generated from a light emitting chip to the outside. The heat conducting slug includes a first slug, a second slug formed on the first slug, and a third slug formed on the second slug, wherein the light emitting chip is mounted to the third slug, and the second and third slugs respectively shaped to have edges are arranged to cross each other. In this configuration, heat generated from a light emitting chip follows a heat dissipation path, in which the heat is gathered at edges of one slug and dissipated therefrom and then gathered toward edges of another slug, arranged to cross the one slug. Accordingly, the entire heat dissipation path is not concentrated at a specific region but generally distributed widely, thereby improving a heat dissipation effect of the heat conducting slug.

摘要： Disclosed is a manufacturing method of a light emitting diode. The manufacturing method comprises the steps of preparing a substrate and mounting light emitting chips on the substrate. An intermediate plate is positioned on the substrate. The intermediate plate has through-holes for receiving the light emitting chips and grooves for connecting the through-holes to one another on its upper surface. A transfer molding process is performed with a transparent molding material by using the grooves as runners to form first molding portions filling the through-holes. Thereafter, the intermediate plate is removed, and the substrate is separated into individual light emitting diodes. Accordingly, it is possible to provide a light emitting diode in which the first molding portion formed through a transfer molding process is positioned within a region encompassed by cut surfaces of the substrate. Since the first molding portion is positioned within the region encompassed by the cut surfaces of the substrate, second molding portions can be symmetrically formed on the side surfaces of the first molding portions in various manners.

摘要： The present invention provides a light emitting device which comprises a blue light emitting diode, and at least an orthosilicate based phosphor for emitting light ranging from a green to yellow regions and a nitride or oxynitride based phosphor for emitting light in a red region over the light emitting diode. Accordingly, since white light with a continuous spectrum ranging from green to red can be implemented, a light emitting device with improved color rendering can be provided, and the light emitting device can be used for a general illumination or a flash. Further, since the phosphors having stable chemical characteristics against their external environment such as moisture are employed, the stability in optical characteristics of the light emitting device can also be improved.
