First Claim
1. A light-emitting diode (LED) lamp comprising:
- a frame;
a power circuit carried by the frame;
a driver circuit electrically coupled with the power circuit;
an optical member carried by the frame and comprising a reflective surface and a lower surface, the reflective surface defining an optical cavity;
a light source support member carried by at least one of the optical member and the frame and defining a first aperture; and
a light source carried by the light source support member and comprising a plurality of LED dies that are electrically coupled to and driven by the driver circuit;
wherein the light source support member is positioned proximate to the lower surface and generally conforms to a shape of the lower surface forming a gap therebetween defined as a second aperture;
wherein the light source support member is configured to carry the light source in an orientation such that light emitted by the plurality of LED dies is incident upon the reflective surface; and
wherein the reflective surface is configured to reflect light incident thereupon in the direction of and through each of the first aperture and the second aperture.

Abstract
An LED lamp includes a frame, a power circuit, a driver circuit coupled with the power circuit, an optical member comprising a reflective surface and a lower surface, the reflective surface defining an optical cavity, a light source support member defining a first aperture, and a light source comprising a plurality of LED dies coupled to and driven by the driver circuit. The light source support member is positioned proximate to the lower surface and generally conforms to a shape of the lower surface forming a gap therebetween defined as a second aperture. Additionally, the light source support member is configured to carry the light source in an orientation such that light emitted by the plurality of LEDs is incident upon the reflective surface. Furthermore, the reflective surface is configured to reflect light incident thereupon in the direction of at least one of the first aperture and the second aperture.
