Adaptable Biologically-Adjusted Indirect Lighting Device and Associated Methods

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;
• 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;
• and
• a plurality of suspension arms configured to attach to and carry the light source support member;
• wherein the plurality of suspension arms are attached to at least one of the frame and the optical member;
• 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;
• wherein 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;
• wherein the driver circuit is adapted to drive the plurality of LED dies to emit a pre-sleep light having a first spectral power distribution, a general illuminating light having a second spectral power distribution, and a phase shift light having a third spectral power distribution;
• wherein the pre-sleep light is configured to have a first biological effect in an observer;
• and
• wherein the phase shift light is configured to have a second biological effect in an observer.
