Systems and methods for of dimming generally considered to be non-dimmable with conventional dimmers. An exemplary dimming module accepts a power source for a light source and a dimming signal. The dimming module modifies the power signal and generates a modified power signal capable of dimming LED light sources (and other light sources) that are generally considered to be non-dimmable with conventional dimmers. The dimming signal can be a wireless signal. Exemplary embodiments include a computer application executing on a computer or handheld computer that can be used to remotely dim, via the dimming module, one or more LED light sources (and other light sources) that are generally considered to be non-dimmable with conventional dimmers.

A daylighting device includes a photo-voltaic (PV) device that is mounted in or proximate to the daylighting device that provides sunlight to a service area. The PV device generates a power signal from incident sunlight. The power signal provides operational power to circuitry associated with the daylighting device, such as a transmitter that transmits a value representing the intensity of light on or near the daylighting device. This signal, which is generated either from the power signal or from a signal provided by a photosensor mounted in or proximate to the daylighting device, may be used by a control system to adjust light levels provided by artificial light sources to supplement the sunlight provided by the daylighting device to approach the desired light level in the service area.

The present invention discloses a color changing light and controlling method and apparatus thereof. The controlling method for a color changing light includes: each terminal of one way of four color substrate being connected together and acted as a common end, the common end being connected to a first voltage; two ways of the four color substrate being set up as a group, other terminals of the two ways being connected to a second voltage and a third voltage respectively; and polarities and voltages of the first voltage, the second voltage, and the third voltage being adjusted to turn on or turn off the four color substrate.

Flexible LED light arrays particularly suitable for use in clothing and other articles are disclosed. The light arrays are disposed on flexible printed circuit boards (PCBs). The flexible PCBs include substantially sinusoidal metal contact traces, along which the LEDs are attached at an angle preselected to minimize stresses in the expected directions of bending. The flexible PCBs may have control electronics provided on separate, attachable control boards, which may be either flexible or rigid. The flexible LED light arrays may also be arranged in master-slave configurations with a number of arrays, in which one master control array or board is attached to a number of slave arrays and handles external communication for the slave arrays.

A load control device for controlling the amount of power delivered to an electrical load may include a rectifier circuit configured to receive a phase-control voltage and produce a rectified voltage. A power converter may be configured to receive the rectified voltage at an input and generate a bus voltage. An input capacitor may be coupled across the input of the power converter. The input capacitor may be adapted to charge when the magnitude of the phase control voltage is approximately zero volts. The power converter may be configured to operate in a boost mode, such that the magnitude of the bus voltage is greater than a peak magnitude of the input voltage. The power converter may be configured to operate in a buck mode to charge the input capacitor from the bus voltage when the magnitude of the phase-control voltage is approximately zero volts.

A method of controlling illumination, including transmitting location information from a communication device to a computer; receiving illumination data with the communication device, where the illumination data is generated by the computer based at least in part on the location information; and transmitting an illumination signal from the communication device to a wearable accessory containing at least one light source, where the illumination signal is based at least in part on the received illumination data and is operable to actuate the at least one light source.

A load control system may include load control devices for controlling power provided to an electrical load. The load control devices may include a control-source device and a control-target device. The control-target device may control the power provided to the electrical load based on digital messages received from the control-source device. A user device may discover load control devices when the load control devices are within an established range associated with the user device. The user device and the load control devices may communicate via a wireless communications module. The established range may be adjusted based on the configurable transmit power of the user device or the wireless communications module associated with the user device. A discovered control-target device may be associated with a control-source device to enable the control-target device to control the power provided to the electrical load based on digital messages received from the control-source device.

A method of charging a light bulb is disclosed. A processor within the light bulb detects a state-of-charge of the battery and if it is below a predetermined dynamic battery state-of-charge threshold then the transceiver sends a wireless signal from the light bulb to a remote light switch with instructions to supply power to the light bulb. The predetermined dynamic battery state-of-charge threshold may be determined based on historical light use data during an on-peak energy time period. The predetermined dynamic threshold allows a battery in the light bulb to supply energy to the light bulb during on-peak hours and recharge during off-peak hours.

An improved LED lighting system is provided for overhead ceiling lighting, as well as for other uses. The LED lighting system comprises elongated linear lamps having an LED luminary as a source of illumination and configured to operate as a node of an automated networked lighting system. The linear LED lamps have internal modular network connectors and control components so that they can receive control data and power signals over a single network cable according to a standardized power and data network communications architecture such as Ethernet. The system includes connector assemblies designed to securely mount the networkable linear LED lamps to conventional tube lamp lighting fixtures or to another support housing and to provide integrated power and data connectivity to internal components of the lamps. In one form, the disclosed system includes a network enabled snap-fit connector assembly mounted to a lighting fixture and configured to provide Ethernet power and data connectivity to the lamp. The LED lamps have first and second mechanical connectors at opposite ends of the lamp body, and the snap-fit connectors are configured to secure the lamps to an overhead lighting fixture or other support structure as an incident of the lamp ends moving relative to the mounting connectors in a substantially straight path that is transverse to the length of the body into an engaged position. The snap-fit connectors are also configured to form a network connection with an internal modular network connector associated with the lamp with the lamp mounted in its operative state on a support. In another form, a clipping mechanism is provided for mounting linear networkable LED lamps to an overhead grid ceiling system.

An illumination system and method is provided for readily mapping a plurality of scenes along a dimcurve form a natural show for one or more groups of LED illumination devices. Mapping can be performed using a graphical user interface on a remote controller wirelessly linked to the illumination devices. A keypad is preferably configured for button control of changes to color temperature as a function of brightness along each of the various dimcurves for each of the various groups of illumination devices controlled by a corresponding keypad to allow momentary or persistent override and reprogram of the natural show. Modification to a scene further comprises modifications to scenes before and after the currently modified scene to provide a smoothing dimcurve modification. Global keypad can be used to control multiple zones arranged throughout a structure to switch between a natural show that emulates outdoor sunlight conditions to a panic show when an intruder is detected.
