An LED light system has an LED light module for inserting into a standard fixture. The fixture has a housing and cover for sealing the enclosure. The LED module contains a shell or outer surface having a matching form factor as the housing for making physical contact with the housing over a sufficient surface area to provide good thermal contact. A substrate is mounted on a support structure. A plurality of LEDs is disposed on the substrate. A heat transfer agent or medium transfers heat from the LEDs to the housing. The outer surface of the LED module spreads the heat over its surface area and firmly contacts the surface of the housing for good thermal transfer. The heat transfer medium is made of a thermally conductive material such as aluminum or copper and formed to contact a surface area of the LED module.

A light emitting diode (LED) light engine includes a substrate for supporting the LED light engine. Conductive traces are formed over the substrate using a thick film screen printing, physical vapor deposition, chemical vapor deposition, electrolytic plating, printed circuit board fabricating, or electroless plating process. The conductive traces include mounting pads. LEDs are mounted to each of the mounting pads for electrical interconnection. The LEDs include red LEDs, green LEDs and blue LEDs. Each of the blue LEDs is at least partially covered with a yellow phosphor coating compound. The concentration of the yellow phosphor coating compound is controlled to allow the emission of blue and yellow spectrum light energy from each blue LED. Emissions of light energy from the red LEDs, green LEDs and blue LEDs are combined to achieve a target correlated color temperature and a target color rendering index for the LED light engine.

A heat transfer system is presented for managing thermal transients, thus providing engineers greater flexibility in designing thermal solutions for applications subject to transient heat-generation. A heat reservoir device for managing a heat input subject to transient conditions includes a heat transfer subsystem having a first end and a second end, where the first end is thermally coupled to the heat input; a heat storage subsystem coupled to the second end of the heat transfer subsystem, where the heat storage subsystem comprises a phase change material responsive to the transient conditions. The excess heat load during transient operation is temporarily absorbed by the latent heat of fusion when the phase change material changes its phase from solid to liquid. Subsequently, the absorbed heat can be released back to the ambient via a heat rejection subsystem. This allows engineers to design smaller heat sinks capable of accommodating given transient conditions.

Subsequently, the absorbed heat can be released back to the ambient via a heat rejection subsystem. This allows engineers to design smaller heat sinks capable of accommodating given transient conditions. This results in heat sinks which are lower cost and smaller size, or which reduce the requirement to provide higher airflow, thereby also decreasing cost and noise, and increasing reliability.

A light-emitting diode lamp includes a light engine, a power assembly, and a heatsink. The light engine includes a plurality of light-emitting diodes, and the power assembly includes a socket disposed at one end of the power assembly and a heat spreader plate disposed at another end of the power assembly opposite the socket. The light engine is mounted to the heat spreader plate. The power assembly further includes a power supply circuit that is electrically coupled to the socket and to the light engine. The socket is configured to electrically couple the power supply circuit to an external electrical source. The heatsink encircles the power assembly and is thermally connected to the light engine. The heatsink also includes a plurality of perforations, which are arranged to facilitate a natural convection airflow over and through the heatsink.

An LED lighting device for use in place of a commercial-standard light bulb. For example, a commercial-standard light bulb typically has an outer surface profile, generally defining its shape and the LED lighting device has its own surface profile which substantially mimics the surface profile of the commercial-standard light bulb. Additionally, LED lighting device may further comprise a heat sink for dissipating energy generated by the LED lighting device. In accordance with various embodiments, the heat sink creates the LED lighting device's outer surface profile and is configured to substantially mimic the outer surface profile of the commercial-standard light bulb.
