Abstract:
An electrical power distribution unit for an electrical system has a printed circuit board with a punched grid arranged thereon. An electrical component is arranged on the printed circuit board on a side of the punched grid. An electrical contact of the electrical component projects through a passage opening in the printed circuit board. The punched grid is arranged between the electrical component and the printed circuit board, and an opening is formed in the punched grid in an area around the electrical contact. The punched grid has a current infeed which comprises a plurality of tongues. At least one of the tongues is bendable out of a plane of the punched grid in such a way that two of the tongues form a mutually adjacent common portion, which is electrically contactable by an electrical plug connector.

Abstract:
A heat radiating structure for a pin type power LED is provided to effectively release the heat generated through the first lead frame connected to the LED device by setting up the radiating unit in the space between a molding unit of substrate and the LED. An LED device(1) is settled on the settling portion extended to the first lead frame. The LED device supplies the power through a lead from the outside. A stopper(4) is formed at one end of leads(5,5') of two lead frames(7,6). A radiating unit(10) is installed in the formed space between a molding unit(8) and a substrate(3) of LED. The radiating unit delivers the heat generated from the LED device to the lead of the first lead frame. The delivered heat is delivered to the radiating unit contacted with the lead.
