Abstract

Apparatus and methods for controlling a fixture are provided. The fixture may include a circuit. The circuit may include a radio. The radio may be configured to transmit and receive using one, two or more different protocols. The fixture may be part of an IoT network. The IoT network may include a plurality of one or more fixtures. The fixtures may be in communication with the Internet via a router. The IoT network may be an IoT network that does not include a dedicated multi-protocol gateway as an intermediary between the fixtures and the router. One or more of the fixtures may be designated as a multi-protocol gateway for the IoT network. A fixture that is not designated as the multi-protocol gateway may have communication via one or more of the protocols disabled.

Abstract

Apparatus and methods for lighting. The apparatus may include a power supply. The apparatus may include a controller. The controller may be configured to receive power from the power supply. The controller may be configured to receive a dimming signal generated external to the controller. The controller may be configured to receive from a user selection that includes a CCT partition set-point. The controller may be configured to transmit to a light source lighting power. The lighting power may correspond to the dimming signal. The lighting power may correspond to the CCT partition set-point. The light source may include a high correlated color temperature ("CCT") LED. The light source may include a low CCT LED. The CCT partition set-point may correspond to a selected value of a partition of power between the high CCT LED and the low CCT LED.

Abstract

Apparatus, methods and instructions for disinfecting air. The apparatus may include, and the methods may involve, a fixture. The fixture may include a germicidal light source. The fixture may include a fan. The fan may circulate air through a volume into which the germicidal light source propagates germicidal light. The light source may be configured to emit, upward from a horizontal plane, a beam that, absent reflection off an environmental object, does not cross the horizontal plane. The apparatus may include a shield that prevents light from the light source from crossing the horizontal plane. The sensor may face upward from the horizontal plane. The sensor may face downward from the horizontal plane.

Abstract

Various embodiments are directed to methods and apparatus relating to fan and/or lighting control. Some embodiments are directed to the use of RF and WiFi control in a fan device to control fan status and speed and/or fan light on/off status and intensity. Some embodiments are directed to a controller with an RF interface that is used to control a fan device which includes a fan motor and may also include a lighting device. The controller in some embodiments is in the form of a wall control module which may be mounted in a standard electrical wall box in a room in which the fan device to be controlled is located. Some embodiments are directed to apparatus for controlling fan system operation including one or more fan devices that include a DC fan motor and circuitry for powering and controlling the DC fan motor.

Abstract

LED related lighting methods and apparatus are described. Various features relate to water tight light fixtures. Some of the fixtures are spotlights while other fixture are intended for in ground use. The light fixtures in at least some embodiments include power control features. In spotlight embodiments beam angle and power or light output can be controlled without opening the light assembly or compromising the water tight seals which also protect against dirt. In ground embodiments support tilt angle setting which allow a user to set the light fixture to one or more tilt angles. Beam angle can also be changed in some embodiments as well as power control. Beam angle, power control and tilt angle adjustments are supported in some embodiments but need not be supported in all embodiments with some embodiments using one or more of the described features but not all features.
