TLDR
In this article, the authors defined a set of requirements for a wall plug efficiency of at least 90 lumens per Watt, including: a lamp (600) comprising a solid state light emitter (450), the lamp being an A lamp, and providing a wall-plug efficiency of 90 lumen per Watt; also, a lamp(400), comprising a light transmissive housing (12) at least one solid state lighting emitter and a first heat dissipation element.Abstract:
A lamp (600) comprising a solid state light emitter (450), the lamp being an A lamp and providing a wall plug efficiency of at least 90 lumens per Watt. Also, a lamp (400) comprising a solid state light emitter (450) and a power supply, the emitter being mounted on a heat dissipation element (420), 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(10), comprising a light transmissive housing (12) 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 (74) for creating flow of ambient fluid.read more
