Abstract
Packages for containing one or more light emitting devices, such as light emitting diodes (LEDs), are disclosed with an efficient, isolated thermal path. In one embodiment, LED package can include a thermal element and at least one electrical element embedded within a body. The thermal element and electrical element can have the same and/or substantially the same thickness and can extend directly from a bottom surface of the LED package such that they are substantially flush with or extend beyond the bottom surface of the LED package. The thermal and electrical element have exposed portions which can be substantially flush with lateral sides of the body such that the thermal and electrical element do not have a significant portion extending beyond an outermost edge of the lateral sides of the body.
