Heat sinks and lamp incorporating same

摘要

A lamp comprising a solid state light emitter, the lamp being an A lamp and providing a wall plug efficiency of at least 90 lumens per watt. Also, a lamp comprising a solid state light emitter and a power supply, the emitter being mounted on a heat dissipation element, the dissipation element being spaced from the power supply. Also, a lamp, comprising a solid state light emitter and a heat dissipation element that has a heat dissipation chamber, whereby an ambient medium can enter the chamber, pass through the chamber, and exit. Also, a lamp, comprising a light emissive housing at least one solid state lighting emitter and a first heat dissipation element. Also, a lamp comprising a heat sink comprising a heat dissipation chamber. Also, a lamp comprising first and second heat dissipation elements. Also, a lamp comprising means for creating flow of ambient fluid.

主权项

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.
