Abstract:
1. A light emitting diode (LED) assembly, comprising: a first substrate carrying a first plurality of LEDs mounted thereon, and a second substrate spaced apart from the first substrate, the second substrate carrying a second plurality of LEDs mounted thereon, the first substrate including a plurality of apertures thereon for allowing air flow therethrough such that the first and second substrates are thermally connected for thermal distribution between the substrates; and wherein each of the LEDs on the first substrate is offset by a distance from a corresponding LED on the second substrate, and wherein the plurality of apertures disposed on the first substrate are each substantially aligned with a corresponding LED mounted on the second substrate for allowing light emissions from the LEDs on the second substrate to pass through the first substrate.
