Methods and apparatus for touch-sensitive lighting control

A lighting assembly, comprising:

• a body member configured to be coupled to an external structure;
• an optical element coupled to the body member, the optical element being configured to direct a light beam toward a predetermined display area;
• a lighting unit disposed in the body member, the lighting unit including an array of light-emitting elements, one or more of the array of light-emitting elements being configured to emit the light beam toward the optical element;
• a touch-sensitive surface coupled to the body member, the touch-sensitive surface including a touch sensor configured to provide at least one lighting control signal in response to a lighting display touch command by a user, the lighting display touch command being effected by either a one-location touch command action or a two-location touch command action;
• and
• a control circuit disposed in the body member, the control circuit being coupled to the lighting unit and the touch-sensitive surface, the control circuit being configured to interpret the at least one lighting control signal generated by the lighting display command action as one of a plurality of lighting display actions, the plurality of lighting display actions including emitting the light beam from selected light-emitting elements of the array of light-emitting elements to establish a location of the light beam and a size of the light beam in at least one spatial dimension, and controlling an intensity of the light beam emitted from the selected light-emitting elements,
• wherein the body member has a substantially triangular cross-section including the optical element on a first side, the touch-sensitive surface on a second side, and a mounting surface on a third side and the optical element, the touch-sensitive surface, and the mounting surface form a light emitting chamber surrounding the array of light-emitting elements, wherein the light emitting chamber has a substantially triangular cross-section.
