LED lamp

摘要

A thermal isolation arrangement for an LED lamp is disclosed. Embodiments of the invention provide thermal isolation between the power supply and the LED assembly of an LED lamp, in most cases allowing the power supply to operate in a lower temperature range than would otherwise be possible. At least one contact feature is provided between the power supply and the LED assembly to maintain a thermal transfer gap between the power supply and the LED assembly. A contact feature can be, for example, a triangular ridge or a conical protrusion. In some embodiments, a thermal isolation device provides the contact feature or contact features. An LED lamp according to example embodiments of the invention can have a modular design and/or can include an Edison base and/or an optical element or optical elements disposed to emit light from the LED lamp.

主权项

1. An LED lamp comprising:
an LED assembly including a first plurality of slots; a power supply portion electrically connected to the LED assembly, the power supply portion including a first plurality of tabs; and a thermal isolation device further comprising:
a first face including a second plurality of tabs that engages the first plurality of slots with the first face proximate to the LED assembly;a second face proximate to the power supply portion;a second plurality of slots to engage the first plurality of tabs; andwherein contact features are arranged on the first face and the second face of the thermal isolation device to maintain one thermal transfer gap between the power supply portion and the second face of the thermal isolation device and another thermal transfer gap between the LED assembly and the first face of the thermal isolation device wherein the thermal transfer gap between the power supply portion and the second face measures from 0.1 mm to 5 mm.
