    摘要: Provided is a circuit for controlling a level of brightness of a light electrically coupled to a dimming circuit including control leads configured to provide a dimming control voltage to the dimmable driver, the dimming control voltage having a permissible voltage range. The circuit includes a photo sensor for detecting an ambient light level in the vicinity of the light and a clamp controller for selectively reducing the dimming control voltage to a clamped voltage range less than the permissible voltage range. Also included is a feedback controller for adjusting the dimming control voltage in response to a detected ambient light level, the dimming control voltage being within the clamped voltage range.

    摘要: A control device for power delivered to electrical loads in a load control system via respective load control devices may comprise a programming user interface for programming the operation of the load control system. The control device may be configured to select one or more load control devices in response to successive actuations of a programming button of the programming interface. The control device may be configured to controllably illuminate visual indicators of the programming interface to indicate which of the load control devices is selected in response to successive actuations of the programming button. The control device may transmit programming information to the load control devices. The programming information may determine which of the load control devices are responsive to a digital message transmitted on the digital communication link.

    摘要: A lifestyle lighting solution using a controller with program codes for managing night time illumination is disclosed; wherein the night time illumination is divided into at least two illumination modes including a regular illumination mode for providing early evening illumination and an user friendly illumination mode for providing a mid night illumination with a soft on process to avoid or mitigate an eye irritating hardship. The conversion time point to switch from a regular illumination mode to an user friendly illumination mode is controlled by a timer configured in an external control device. The timer is programmed to operate one of three time setting methods including an anytime setting method, a fixed time point setting method and a fixed time period method.
