摘要: An LED apparatus with temperature self-regulating, over-temperature protection, and over-current protection function comprises an LED chip, a heat dissipation plate, a heat conductive layer and a temperature control device. The heat dissipation and the heat conductive layer disposed thereon carry the LED chip and dissipate the heat generated from the LED chip that is connected to an electric power source for luminance. The temperature control device exhibiting PTC behavior is electrically connected between the LED chip and the electric power source in series, and the distance between the LED chip and the temperature control device is less than 3 cm. The heat conductive layer can consist of polymeric dielectric material and has a heat conduction coefficient larger than 1.0 W/mK at 25° C.

摘要: A thermal conductive apparatus includes a first electrode sheet, a second electrode sheet, a cooling sheet, and a polymer dielectric layer. The polymer dielectric layer physically contacts the first electrode sheet and the second electrode sheet via the top surface thereof, and the cooling sheet via the bottom surface thereof, and exhibits a coefficient of thermal conductivity above 1.0 W/mK. The interfaces between the first electrode sheet, the second electrode sheet, the cooling sheet, and the polymer dielectric layer include at least one micro-rough surface. The micro-rough surfaces include plural nodules thereon formed by electrodeposition. The first electrode sheet and the second electrode sheet are electrically insulated from each other and are connected to a power source and a heat-generating device to form a conductive circuit loop.
