Abstract: A system and method are provided herein for communicating with and controlling various devices using visible light communication (VLC). According to one embodiment, a method is provided for extending a communication range of a VLC system comprising a plurality of controlled devices and a remote-control device. Such a method may include, for example, transmitting a communication message from a remote-control device to a first controlled device located within range of the remote-control device, wherein the communication message is transmitted through free space using visible light, and extending the communication range of the VLC system to a second controlled device, which is located outside of the range of the remote-control device, by using the first controlled device to retransmit the communication message through free space using visible light to the second controlled device.

Abstract: Systems and methods are disclosed for a load control system which produces a show by adjusting one or more parameter values, such as color temperature, intensity, spectrum, volume, load state, and position of a window covering, as a function of a show time equal to a current time of day. The load control system is responsive to receiving commands to adjust the show time with respect to the current time of day. The load control system is configured to respond to the received commands by initiating a temporary system override in which the one or more parameter values may rewind or forward in time according to the defined show. The temporary override may exit and the defined show may resume at the current time of day after a predetermined amount of time has passed, at a reset time, or in response to a command.

Abstract: Intelligent illumination device are disclosed that use components in an LED light to perform one or more of a wide variety of desirable lighting functions for very low cost. The LEDs that produce light can be periodically turned off momentarily, for example, for a duration that the human eye cannot perceive, in order for the light to receive commands optically. The optically transmitted commands can be sent to the light, for example, using a remove control device. The illumination device can use the LEDs that are currently off to receive the data and then configure the light accordingly, or to measure light. Such light can be ambient light for a photosensor function, or light from other LEDs in the illumination device to adjust the color mix.

Abstract: An illumination device and method is provided herein for controlling an LED illumination device, so that a desired luminous flux and a desired chromaticity of the device can be maintained over time as the LEDs age. According to one embodiment, the method determines an expected wavelength value and an expected intensity value for each emission LED included within the illumination device at the drive current currently applied to the emission LED and the present emitter forward voltage. In addition, the method determines a photodetector responsivity for each emission LED at the expected wavelength value and the present photodetector forward voltage. The photodetector responsivity calculated for each emission LED is used as a reference for adjusting the lumen output of the emission LED to account for LED aging affects.

Abstract: Illumination devices with improved color mixing optics are disclosed herein for mixing the colors produced by a multi-colored LED emitter module to produce uniform color throughout the entire beam angle of the output light beam, along with smoother edges and improved center beam intensity. Embodiments disclosed herein include a unique arrangement of multi-color LEDs within an emitter module, a unique exit lens with different patterns of lenslets on opposing sides of the lens, and other associated optical features that thoroughly mix the different color components, and as such, provide uniform color across the output beam exiting the illumination device. Additional embodiments disclosed herein include a unique arrangement of photodetectors within the primary optics structure of the LED emitter module that ensure the optical feedback system properly measures the light produced by all similarly colored emission LEDs.

Abstract: An LED lamp and method are provided for autonomously changing the output brightness and color temperature of a plurality of LED strings to follow a first dimcurve in temporal synchronization with at least one other LED lamp. Synchronization is achieved based on a time of day determined using a clock signal. The output brightness and color temperature can transition from the first dimcurve to a second dimcurve over a predetermined number of scenes. The number of scenes is a function of a difference between the first dimcurve and the second dimcurve in at least one of the output brightness and the color temperature.
