摘要:
The invention relates to a high power LED package, in which a package body is integrally formed with resin to have a recess for receiving an LED chip. A first sheet metal member is electrically connected with the LED chip, supports the LED chip at its upper partial portion in the recess, is surrounded by the package body extending to the side face of the package body, and has a heat transfer section for transferring heat generated from the LED chip to the metal plate of the board and extending downward from the inside of the package body so that a lower end thereof is exposed at a bottom face of the package body thus to contact the board. A second sheet metal member is electrically connected with the LED chip spaced apart from the first sheet metal member for a predetermined gap, and extends through the inside of the package body to the side face of the package body in a direction opposite to the first sheet metal member. A transparent sealant is sealingly filled up into the recess. The LED package raises thermal radiation efficiency with a simplified structure in order to reduce the size and thickness thereof.

The invention relates to a side-emitting LED package and a manufacturing method thereof. The side-emitting LED package includes a substrate with an electrode formed thereon, and a light source disposed on the substrate and electrically connected to the electrode. The side-emitting LED package also includes a molded part having an upper surface with a center thereof depressed concavely, covering and protecting the substrate and the light source, and a reflection layer covering an entire upper surface of the molded part to reflect light sideward from the molded part which forms a light transmitting surface. The package is not restricted in the shape of the molded part and is not affected by the LED chip size, enabling a compact structure. The invention can also process a substrate by a PCB process, enabling mass-production.

The chip coated LED package includes a light emitting chip composed of a chip die-attached on a submount and a resin layer uniformly covering an outer surface of the chip die. The chip coated LED package also includes an electrode part electrically connected by metal wires with at least one bump ball exposed through an upper surface of the resin layer. The chip coated LED package further includes a package body having the electrode part and the light emitting chip mounted thereon. The invention improves light efficiency by preventing difference in color temperature according to irradiation angles, increases a yield, miniaturizes the package, and accommodates mass production.
摘要:
An LED diode package includes a heat connecting part for mounting a light emitting part on an upper surface thereof, frames electrically connected to the light emitting part while holding the heat connecting part and a molded part fixing the heat connecting part and the frames together. The light emitting part generates light in response to current applied thereto, and the upper surface of the heat connecting part is protruded beyond an upper surface of the molded part to a predetermined height. This can optimize the unique beam angle of the light source thereby to maximize lighting efficiency as well as prevent overflow of the encapsulating material in the assembling process of the lens, which may otherwise soil adjacent components.
