Abstract: An air treatment system includes germicidal air circulation unit with a germicidal chamber with disinfection stages or channels each having UVC LED light engines therein. The air treatment system includes an intake port, an exhaust port and a circulation fan that pushes or pulls air into and through the germicidal chamber. The germicidal chamber can include baffle structures and can contain a metal-oxide material and/or a metal-sulfide material. The air treatment system includes a control unit and sensor that regulates air flow provided by the circulation fan and/or the fluence or power levels of the UVC LED light engines.

Abstract: An emergency lighting system uses a wireless mesh network to control the dimming of luminaires in the event of a power failure or a power outage. Luminaires are commissioned to different dimming power levels depending on localized lighting needs during the power failure of power outage.

Abstract: A sensor, such as a motion sensor and/or an occupancy sensor, a soft switch relay controller, or a power pack can significantly reduce the in-rush current and thereby extend the life of relays and other electrical components susceptible to damage caused by in-rush current or voltage surges. The sensor, soft switch relay controller, and/or power pack can reduce the in-rush current when enabling or disabling a light source.

Abstract: A sensor, such as a motion sensor and/or an occupancy sensor, can include the capability of communicating wirelessly with a user device such that sensor settings can be adjusted via an application running on the user device. The sensor settings may determine when one or more light sources (e.g., a light fixture, a light bulb, a light emitting diode (LED), etc.) turn on and/or the amount of light produced by the one or more light sources.
