Abstract: A lighting tube for uniform illumination is disclosed. The lighting tube includes a conduit having an inner layer, outer layer, and a middle layer between the inner and outer layers. The middle layer has at least two of a phosphor film, a diffusion film, and a UV-blocking film. The lighting tube also includes a light emitting chain located inside of the conduit. The light emitting chain includes control wires and a plurality of light emitting units spaced along the control wires. Each unit has a plurality of faces interconnected to form a polygon when viewed along a central axis, with each face being on a different side of the polygon. Each face has an LED coupled to the control wires. The LED emits light with a wavelength that causes the phosphor film to luminesce. The illumination of the middle layer by the chain is substantially uniform in all radial directions.

Abstract: A lighting system. Implementations may include an AC input power source coupled with a power conditioning and control module adapted output a low voltage high frequency pulse width modulated (PWM) signal. A remote transmission cable may be adapted to carry the low voltage high frequency PWM signal to a remote transformer adapted to convert the low voltage high frequency PWM signal to a high voltage high frequency PWM signal. A charge pump may be included which is adapted to receive the high voltage high frequency PWM signal and increase a voltage of the signal. A gas discharge tube may be coupled to the charge pump. A controller may be coupled to the power conditioning and control module and adapted to operate the gas discharge tube at two or more light intensity levels with the low voltage high frequency PWM signal.

Abstract: A control interface for a visual presentation system. Implementations include a graphical interface including a plurality of parallel lines and plurality of spaces between and adjacent to the plurality of lines that define at least one visual staff. One or more visual notes may be disposed on the at least one visual staff. An output data stream may be included that includes a control sequence of one or more visual element parameters adapted to operate a visual presentation system and corresponding with the one or more visual notes. The output data stream may be coupled with a visual presentation system. One or more music notes on one or more music staffs may be included on the graphical interface adjacent to the at least one visual staff where the one or more music notes are correlated with the one or more visual notes on the at least one visual staff.
