ADJUSTABLE OPTIC AND LIGHTING DEVICE ASSEMBLY
First Claim
1. A lighting device comprising:
- a light source;
an optic device configured to pass at least some light from the light source, the optic device comprising;
a recessed bottom surface facing the light source;
one or more reflective elements arranged on the recessed bottom surface and configured to refract light received from the light source at a critical angle; and
an emitting surface opposite the recessed bottom surface, the emitting surface configured to internally reflect the light refracted by the one or more reflective elements,wherein the lighting device is configured to absorb the light that is internally reflected by the emitting surface;
an optic assembly configured to pivot about the light source, the optic assembly including a holding member having an interior volume in which the optic device is contained; and
a housing member having a first curved surface defining a cavity in which at least a portion of the holding member is received,wherein the holding member has an outer surface having a curvature that is configured to slideably engage with the first curved surface of the housing member when the optic assembly is pivoted about the light source.

Abstract
A lighting device includes: a light source; an optic device to pass at least some light from the light source; an optic assembly including a holding member having an interior volume to contain the optic device; and a housing member having a first curved surface defining a cavity to receive at least a portion of the holding member. The holding member has an outer surface having a curvature that slideably engages with the first curved surface of the housing member when the optic assembly is pivoted about the light source. The optic device includes a recessed bottom surface facing the light source, one or more reflective elements arranged on the recessed bottom surface to refract light received from the light source at a critical angle, and an emitting surface opposite the recessed bottom surface to internally reflect the light refracted by the one or more reflective elements to be absorbed.

11. A lighting device comprising:
-
a heat sink having a first end, a second end opposite the first end, and a side surface between the first end and the second end; a light source contacting the first end of the heat sink; a frame member attached to the first end of the heat sink with the light source interposed between the first end and the frame member, the frame member configured to electrically connect the light source to a plurality of wires; an optic device configured to pass at least some light from the light source; an optic assembly configured to pivot about the light source, the optic assembly including a holding member having an interior volume in which the optic device is contained; and a housing member having a first curved surface defining a cavity in which at least a portion of the holding member is received, wherein the holding member has an outer surface having a curvature that is configured to slideably engage with the first curved surface of the housing member when the optic assembly is pivoted about the light source. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
