A dimmable lighting system may replace a bi-level lighting system without having to modify or supplement the existing wiring between a bi-level control unit and one or more light fixtures. The dimmable lighting system may include a dimming controller that may be configured to replace a bi-level control unit in situ (i.e., e.g., in a wall-mounted dual-gang switch box). The dimmable lighting system may also include a dimming driver that may be coupled to the dimming controller via the existing wiring of the bi-level lighting system. The dimming controller may output to the dimming driver a 0-10 volt DC dimming signal referenced to an AC utility voltage. In response, a dimmable lighting device coupled to the dimming driver may output light over a wide range of dimming light levels. Methods of replacing a bi-level lighting system with a dimmable lighting system are also provided, as are other aspects.

Systems, apparatus, and methods for converting a bi-level lighting system to a dimmable lighting system

A programmable lighting control system integrates time-based, sensor-based, and manual control of lighting and other loads. The system includes one or more groups of controlled lighting areas, which may be, e.g., floors of a building. Each group may have one or more lighting zones, which may be, e.g., individual rooms or offices on a building floor. Each lighting zone includes occupancy and/or daylight sensors that may be wirelessly coupled to a gateway of the group. Each gateway is coupled to a network, such as, e.g., a local area network (LAN). Control software, residing on a computer (e.g., a personal computer or a server) coupled to the network and accessible via the network, remotely communicates with and controls the lighting zones either individually, groupwise, or globally. Each lighting zone can also be locally controlled at the gateway and can function independently of the control software and the gateway.

A programmable lighting control system integrates time-based, sensor-based, and manual control of lighting and other loads. The system includes one or more groups of controlled lighting areas, which may be, for example, floors of a building. Each group may have one or more lighting zones, which may be, for example, individual rooms or offices on a building floor. Each lighting zone includes occupancy and/or daylight sensors that may be wirelessly coupled to a gateway of the group. Each gateway is coupled to a network, such as, for example, a local area network (LAN).

A portable, handheld artificial light detector distinguishes artificial light from sunlight and identifies low-frequency artificial light from high-frequency artificial light. Artificial light includes light from a lamp powered by an AC source. Low frequency light includes, for example, light produced by a magnetic luminaire ballast, while high frequency light includes light produced by an electronic luminaire ballast.

An occupancy sensor is provided that can operate within an extended range of AC and DC input voltages, enabling the sensor to be used in different electrical environments. The sensor draws substantially only an amount of current required by the sensor at the moment, which reduces power waste. The sensor includes a relay that de-energizes when occupancy is sensed and energizes when occupancy is not sensed. This reduces peak sensor current, permitting the sensor to maintain a more constant average current. A shutdown mode is provided to prevent sensor damage or destruction should excessive output current be drawn from the sensor. The sensor also includes a second output at which occupancy signals are provided when an occupancy signal is present at the first output.

Highly versatile occupancy sensor

Occupancy sensors are presented that include a flat lens for focusing detecting beams into narrower, longer range beams than those of conventional curved lenses. A sensing circuit generates a detecting beam that is substantially perpendicular to the flat lens. The flat lens has a plurality of lens segments that provide long, intermediate, and short range sensing beams. To facilitate positioning of an occupancy sensor, the sensor includes a plurality of indicators that indicate the sensor's long and short range sensing limits. An override timer circuit is provided that upon activation sets the occupancy sensor in occupancy mode for a predetermined time period. A warm-up timer circuit is also provided that upon power-up automatically sets the occupancy sensor in occupancy mode for a predetermined warm-up period. These occupancy sensors are well-suited for environments with long aisles, high ceilings, and high intensity discharge lighting.
