Abstract

Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity. The apparatus may include a mechanical power state selector. A user may use the power state selector to select between LED light sources that are arranged to illuminate in different directions. The apparatus may include a CCT state selector. A user may use the CCT state selector to select a CCT for one or more LED light sources. The CCT may be produced by combining light from one or more LEDs of different CCTs.

Dependent claims

Apparatus comprising:

a first LED light source that is in a housing and that is configured to emit light in a first direction;
a second LED light source that is in the housing and that is configured to emit light in a second direction that is different from the first direction;
a circuit that is:
in the housing;
and
configured to cause each of the first LED light source and the second LED light source to emit light at:
a first intensity;
and
a second intensity that is different from the first intensity;
and
an on-board mechanical intensity-selector;
wherein:
the first intensity and the second intensity are selectable via the on-board mechanical intensity-selector;
and
the circuit is configured to change, responsive to a manual adjustment of the on-board mechanical intensity-selector, a magnitude of an electrical current passing through the first LED light source and the second LED light source.
