Abstract: A lighting device having a light emitting diode (LED). The device includes a metal substrate having a surface. A dielectric coating layer is superimposed on the surface of the metal substrate. A light emitting diode (LED) is supported on the dielectric coating layer. The metal substrate serves as a heat sink for the heat emitted by LED during operation.

Abstract: A circuit device and a method for providing an interface between a circuit device comprised of a porcelain enameled metal substrate and an external electrical conductor such as a wire or a lead. An aperture is formed in the substrate at the location where the connection is desired. An eyelet is then placed in the aperture. Crimping or other means are used to form a mechanical connection to the substrate and causes the eyelet to be retained in the aperture. The wire or lead of an electronic component is then inserted into the eyelet. The wire or lead is then soldered to the eyelet providing a joint of high mechanical strength.

Abstract: A touch control panel for use in controlling an electrical device such as a washer, dryer, stove, microwave or related piece of electrical equipment. In a preferred embodiment, the touch control panel comprises an outer panel formed of flexible aluminum. The outer panel includes an outer and an inner surface. The inner surface of the aluminum panel includes a first circuit formed along at least a portion of the surface. The control panel also includes an inner support panel comprising a porcelain enamel metal substrate. The porcelain enamel metal substrate affords a highly durable and rigid degree of support to the control panel. The support panel has an inner surface which is spaced from and disposed substantially parallel to the inner surface of the outer panel. The inner surface of the metal substrate has formed along at least a portion thereof a second circuit. Upon application of tactile pressure upon the outer surface of the outer panel, the first circuit contacts the second circuit.
