A method is provided for preparing a plurality of groupings of light-emitting diode (LED) lights, where each grouping comprises a plurality of LEDs that fall within a specified color range from respective target x, y color points, comprising: receiving a source group of LEDs from a supplier, the source group having a specified color range; measuring a color value for each LED in the source group with a color sensor; storing the measured color value along with a unique LED identifier; creating a first grouping of LEDs within the specified color range from a first target x, y color point by identifying a plurality of LEDs from the stored color values that fall within the specified color range and doing the same for a second grouping of LEDs. Lighting assemblies are constructed based on the group associations.

A system for sensing and maintaining the light level within an area. The invention comprises multiple lux sensor readers that function to measure the current light level within an area. One or more controllers are used to control the dimming level of each light source in accordance with the readings received from the plurality of lux sensors. The readings are averaged such that over time any extreme readings are averaged out. The light level of the plurality of light sources is adjusted in accordance with the averaged readings. This virtually eliminates areas in the room where the light is too dim or too bright and serves to average out any manufacturing and component tolerance differences between devices. In addition, the invention comprises the optional assignment of a weight factor to each reading or average to further provide the ability to give more importance to certain regions in the room over others thus further assisting in eliminating areas where the light is either too dim or too bright. The system includes control units, controllers, controls for window, skylight, light pipe and shading, HVAC controls, lighting loads and light sensors (lux readers) that are used to construct the lighting control system of the present invention. Readings from the one or more lux sensors are processed by one or more controllers and in response thereto, one or more commands are generated for directing the actions of controllers to which the lighting loads are attached.

An apparatus and method place a node in an unconfigured state, with the apparatus and method functioning within an electrical network including a plurality of such nodes. Each node is adapted to communicate over a communications network. Such electrical networks can be implemented utilizing the CEBus (EIA-600 standard) or LonWorks communications systems. The apparatus and method operate in a LonWorks communications system by placing a node in an unconfigured state for installation or maintenance purposes. A push button switch is in a suitable location in the apparatus to be accessed by a user. The switch is coupled between a service pin of a Neuron chip and ground. Under control of an executable application program, pressing the switch for a predetermined length of time causes the node to be placed in the unconfigured state.

An apparatus for and method of inhibiting and overriding the normal operating mode of one or more input devices connected to a communications network. The present invention functions within an electrical network made up of a plurality of input devices wherein a group of input devices is capable of commanding an electrical control device to apply and remove electrical power from an electrical load connected thereto. The input devices or nodes communicate with the electrical control device over a communications network. When one of the input devices is turned off, the normal operating mode of all the other input sensors is inhibited. The electrical control device remains inhibited until all the input devices are no longer in the off position. Thus, electrical power to the load controlled by the electrical control device remains disconnected until all input devices are in the on position. Local and remote signaling, control and indication diagnostic and monitoring functions are also provided.

A disclosed power supply includes a power factor correction circuit including a switch, an inductor having a first terminal connected to an input voltage, and a second terminal connected to the switch, a storage capacitor and a load, a value of the inductor selected to operate the power factor correction circuit in discontinuous conduction mode, and a controller programmed to operate the switch to increase a power factor of the power supply. The switching frequency of the switch is periodically adjusted to reduce electromagnetic interference.
