Abstract
A device is disclosed for producing light that may include one or more printed circuit boards (PCBs), an electronics package may be disposed about the first surface of one or more of the PCBs and a housing. The PCBs may include a metal layer and a core, and, in some aspects, may include multiple cores interposed between multiple metal layers, and in some embodiments a backplane may be disposed along the core(s). A plurality of PCB'"'"'s may be set apart and connected by pins to dissipate heat from one PCB to another, and/or to convey electrical connectivity. Pins may be configured to pass through or into one or both the PCBs including the cores to conduct heat generated by the electronics package away for dispersion. In some embodiments, the pins may pass into the backplane. The PCBs may include LEDs, lights, computer devices, memories, telecommunications devices, or combinations of these. The device may also include a housing to contain the plurality of PCBs such that air flow may enter the housing and pass by the pins for cooling of the PCBs and electronics thereof. The housing may also be configured to permit external power to be applied to the PCBs within the apparatus.
