Systems and methods for solid-state light source heat management are provided. A solid-state light source, e.g. having one or more LEDs, can be mounted within an enclosure. In some embodiments, a heat sink associated with semiconductor material and / or power electronics can be placed on a separate side of the enclosure that is thermally insulated or separated from the state-light source. The enclosure can include a first side or portion that allows light from the solid-state-light source (e.g., LEDs) to pass through to a target area.

A method significantly reduces the average power for radio communication in a communication system, such as a system that has applications requiring low communication latency. The method may use a low power radio communication circuit (e.g., a non-heterodyne receiver) to wait for a communication request, taking advantage of the low power consumption of the radio communication circuit. Subsequent to receiving and validating the communication request, the communication system may switch to a more efficient—but higher power—communication circuit. Thus, effective communication is achieved without making undesirable tradeoffs, such as reduced sensitivity.
