摘要:
Disclosed are various methods and apparatus for controlling illumination sources in a networked lighting system. For example, disclosed is an integrated circuit to control at least one illumination source. The integrated circuit includes a data reception circuit; an illumination control signal generation circuit coupled to the data reception circuit; and a clock generating circuit coupled to the data reception circuit for extracting information from serial data input to the integrated circuit in coordination with a clock pulse generated by the clock generating circuit. The illumination control signal generation circuit generates at least one illumination control signal to control the at least one illumination source based on the extracted information.

Methods and apparatus for generating and modulating white light illumination conditions. Examples of applications in which such methods and apparatus may be implemented include retail environments (e.g., food, clothing, jewelry, paint, furniture, fabrics, etc.) or service environments (e.g., cosmetics, hair and beauty salons and spas, photography, etc.) where visible aspects of the products/services being offered are significant in attracting sales of the products/services. Other applications include theatre and cinema, medical and dental implementations, as well as vehicle-based (automotive) implementations. In another example, a personal grooming apparatus includes one or more light sources disposed in proximity to a mirror and configured to generate variable color light, including essentially white light, whose color temperature may be controlled by a user.
摘要:
Methods and apparatus for downloading one or more lighting programs including one or more lighting effects. The lighting program(s) may be downloaded from a web site to one or more LED-based lighting devices that are configured to execute the downloaded lighting program(s) so as to reproduce the lighting effect(s). In various examples, a variety of programming devices may be employed to facilitate wired or wireless downloading, including one or more computers, personal digital assistants (PDAs), cell phones, media players (e.g., MP3 players), and the like. Information may be uploaded to the web site to facilitate selection and/or creation of lighting effect(s) that are included in the downloaded lighting program(s).
摘要:
A system and method for calibrating light output from an LED is provided. The system includes a support on which an LED is positioned, a photosensor to measure the light output from the LED, and means for calibrating and adjusting the light output of the LED. Calibration is accomplished by measuring the light output from the LED, comparing such output against a reference value, and adjusting the measured output against the reference value.
摘要:
Methods and apparatus for providing controllable power via an A.C. power source to LED-based lighting devices having an MR16 configuration. In one example, LED-based MR16 lighting devices may be coupled to A.C. power circuits that are controlled by conventional dimmers (i.e, “A.C. dimmer circuits”). 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.
摘要:
Methods and apparatus for generating essentially white light. In one example, a white light generating apparatus comprises at least one first white LED characterized by a first spectrum, and at least one second white LED characterized by a second spectrum, wherein the first spectrum is substantially different than the second spectrum.
摘要:
Methods and apparatus for illumination of liquids in a variety of environments. In one example, multi-color LED-based light sources are employed to achieve a wide range of enhanced lighting effects in liquids. In another example, a pool or spa is illuminated by one or more multi-color light sources that may be employed as individually and independently controllable devices, or coupled together to form a networked lighting system to provide a variety of programmable and/or coordinated color illumination effects in the pool or spa environment.
摘要:
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.
