摘要:
Separating a source in a stereo signal having a left channel and a right channel includes transforming the signal into a short-time transform domain; computing a short-time similarity measure between the left channel and the right channel; classifying portions of the signals having similar panning coefficients according to the short-time similarity measure; segregating a selected one of the classified portions of the signals corresponding to the source; and reconstructing the source from the selected portions of the signals.

Methods and apparatus for controlled lighting based on a reference color gamut that is shared amongst multiple lighting units. A reference color gamut may be determined for multiple lighting units based on spectral power distributions associated with the lighting units. Variable color light or variable color temperature white light subsequently may be generated consistently and predictably amongst multiple lighting units that are each controlled based on the reference color gamut. Lighting commands received by multiple lighting units may be appropriately processed in each lighting unit, based on a predetermined relationship between the lighting commands and the reference color gamut, to ensure consistent and predictable color or color temperature reproduction amongst the multiple units. In one exemplary implementation, the multiple lighting units include LED light sources to facilitate energy efficient generation and versatile control of variable color light or variable color temperature white light, for general purpose illumination and other applications.

An embodiment of the invention is a system for generating control signals. The system may allow a user to generate an image, representation of an image, algorithm or other effect information. The effect information may then be converted to lighting control signals to be saved or communicated to a networked lighting system. An embodiment of the invention may enable the authoring, generation and communication of control signals such that an effect is generated in a space or area. An embodiment of the invention may provide systems and methods for the control of a plurality of lighting devices in an environment.

Methods for allocating power amongst different source spectrums, or “channels,” of a multi-channel lighting unit, and apparatus that employ such methods. Power allocation methods exploit the total light-generating capability of a lighting unit while maintaining safe operating power conditions, so as to avoid damage to the lighting unit due to excessive thermal power generation. In one example, a power allocation method ensures that a lighting unit operates at or near its maximum power handling capability for a variety of possible high brightness lighting conditions by ascribing a maximum per channel operating power equal to the maximum power handling capability of the lighting unit. The power allocation method then reapportions, if necessary, prescribed operating powers for multiple channels, in response to a given lighting command, such that the ratio of the prescribed powers remains the same but the sum of the channel operating powers does not exceed the maximum power handling capability of the lighting unit.

The systems and methods descried herein relate in part to intuitive methods for creation and design of lighting sequences, e.g., for theatrical, entertainment or advertising purposes, using a software interface. Additionally, the lighting sequences can be coordinated with control of additional devices. Also described herein is a controller capable of executing programs for lighting sequences and modifying the output and/or execution of the program based on external signals. In this way, the final output can be made responsive to external stimuli, or even interactive.

Various exemplary implementations of light emitting diode (LED) based illumination products and methods are disclosed including, but not limited to, glow sticks, key chains, toys, balls, various game accessories, light bulbs, night lights, wall lights, wall switches, wall sockets, wall panels, modular lights, flexible lights, automotive lights, wearable accessories, light ropes, decorative lights such as icicles and icicle strings, light tubes, insect control lights and methods, and lighted air fresheners/scent dispensers. Any of the foregoing devices may be equipped with various types of user interfaces (both “local” and “remote”) to control light generated from the device. Additionally, devices may be controlled via light control information or programs stored in device memory and/or transmitted or downloaded to the devices (e.g., devices may be controlled individually or collectively in groups via a network, glow sticks or other products may be downloaded with programming information that is stored in memory, etc.). Devices also may include sensors so that the generated light may change in response to various operating and/or environmental conditions or a user input. Various optical processing devices which may be used with any of the devices (e.g., reflectors, diffusers, etc.) also are disclosed.

Methods and apparatus for providing power to devices via an A.C. power source, and for facilitating the use of LED-based light sources on A.C. power circuits that provide signals other than standard line voltages. In one example, LED-based light sources may be coupled to A.C. power circuits that are controlled by conventional dimmers (i.e, “A.C. dimmer circuits”). Hence, LED-based light sources may be conveniently substituted for other light sources (e.g., incandescent lights) in lighting environments employing conventional A.C. dimming devices and/or other control signals present on the A.C. power circuit. In yet other aspects, one or more parameters relating to the light generated by LED-based light sources (e.g., intensity, color, color temperature, temporal characteristics, etc.) may be conveniently controlled via operation of a conventional A.C. dimmer and/or other signals present on the A.C. power circuit.
