LED lamp with an interior electrical connection

摘要

An LED lamp includes an enclosure and a base. LEDs are mounted on a first portion of a substrate and an electrical contact is mounted on a second portion of the substrate. The LEDs emit light from the enclosure when energized through an electrical path from the base. A heat sink conducts heat to the ambient environment. The first portion of the substrate is mounted on an outside surface of a tower that extends into the enclosure. The second portion of the substrate is located inside of the tower. An extension is electrically coupled to the base and includes a second electrical contact that is electrically coupled to the first electrical contact.

主权项

1. A lamp comprising:
at least one LED mounted on a submount operable to emit light through an at least partially optically transmissive enclosure when energized through an electrical path from a base, the submount comprising electrical conductors and a dielectric material, the electrical conductors forming at least one anode and at least one cathode for mounting the at least one LED and at least one first electrical contact pad to electrically couple the at least one LED to the electrical path; a tower located within the enclosure and extending in an axial direction, the tower comprising an interior and an exterior in communication with one another through an aperture in the tower, wherein at least a first portion of the submount containing the at least one anode and at least one cathode is located on the exterior of the tower and a second portion of the submount containing the at least one first electrical contact pad extends through the aperture and into the interior of the tower; and electrical circuitry on aboard, the board extending into the interior of the tower, the submount being electrically coupled to the electrical circuitry at the at least one first electrical contact pad by an electrical coupling, the electrical coupling being in the interior of the tower and within the enclosure, where the electrical circuitry and the electrical conductors on the submount are in the electrical path.
