Abstract:
1. A lamp, comprising: at least a first solid state light emitter; and at least a first heat dissipation element that defines at least one heat dissipation chamber, the first heat dissipation element comprising at least one dissipation region sidewall, the first solid state light emitter thermally coupled to the first heat dissipation element, the heat dissipation chamber having at least a first inlet opening and at least a first outlet opening, whereby an ambient medium can enter the first inlet opening, pass through the heat dissipation chamber and exit the first outlet opening, the heat dissipation chamber comprising one or more plenums, the first plenum of the one or more plenums having at least a first end and a second end, whereby fluid can flow from the first end to the second end, the first plenum non-straight so that no straight path can be defined that enters the heat dissipation chamber through the first end, extends within the plenum from the first end to the second end, and exits the heat dissipation chamber through the second end.
