摘要:
An more efficient or higher luminance LED assembly may be formed from a high power LED chip having a first surface, and a second surface, the first surface being mounted to a substrate; the second surface being in intimate thermal contact with a light transmissive heat sink having a thermal conductivity greater than 30 watts per meter-Kelvin. The LED chip is otherwise in electrical contact with at least a first electrical connection and a second electrical connection for powering the LED chip. Providing light transmissive heat sink can double the heat conduction from the LED dies thereby increasing life, or efficiency or luminance or a balance of the three.
摘要:
Systems and methods for protecting electrical components such as light emitting diodes are described. In some embodiments, electrical components are protected from high level electrostatic discharge (“ESD”) events by a circuit board that provides an intrinsic level of ESD protection. At the same time, such electrical components are protected against low level ESD events by one or more diodes that are electrically coupled thereto. The one or more diodes may be thin film diodes comprising at least one layer of p-type semiconductive material and at least one layer of n-type semiconductive material. Devices including ESD protection and methods for manufacturing such devices are also described.
摘要:
A lighting module comprising a base panel and a plurality of light-emitting diode (LED) chips attached directly to the base panel. The LED chips are in electrical communication with conductive traces on the base panel, which deliver a current to the LED chips. Various embodiments of this generally described lighting module are also presented. Additionally, methods of preparing such a lighting module, and system components of the lighting module are presented.
