| Title: |
Linear Lighting Apparatus and Methods |
| Abstract: |
Linear lighting systems and methods. In one example, two or more lighting
elements having an essentially linear or curvilinear shape are coupled
together to form a lighting system. Each lighting element includes a
group of LEDs arranged so as to illuminate the essentially linear or
curvilinear shape of the lighting element. Each element may include LEDs
to generate the same color light, and/or LEDs to generate light of
different colors. Additionally, each element may include one or more
controllers to control the LEDs so as to create a variety of temporal
and/or color-oriented lighting effects. The controller(s) may employ one
or more of a variety of control techniques to control the LEDs, such as
those involving analog control signals or pulse-width modulated (PWM)
control signals. The lighting elements of the system may each be
configured as a "stand alone" unit working within the system, producing
respective lighting effects that may or may not be coordinated with each
other. Alternatively, two or more elements of the system may be
configured as addressable lighting elements to facilitate coordination of
the elements as a networked lighting system. Any of the foregoing linear
lighting systems may be used in a variety of interior or exterior, as
well as direct or indirect, lighting applications. In one example, such
lighting systems are particularly well-suited as replacements or
substitutes for neon lighting installations.
