Abstract: A luminaire having an adjustable color temperature of emitted light includes an input device for receiving an input indicative of a desired color temperature, first, second and third LED arrays each array having different color temperatures, a first LED driver for driving one of the first and third LED arrays, a second LED driver for driving the second LED array, an LED array selector for selectively driving the one of the first and third LED arrays dependent upon the input, and a processor for determining which of the first and the third LED arrays to drive based on the input and controlling the LED array selector and the second LED driver dependent upon the input. The processor utilizes analog dimming above a predetermined noise threshold voltage and PWM dimming below the predetermined noise threshold voltage and combinations thereof. A related method of adjusting a color temperature of light emitted from a luminaire is also provided.

Abstract: A system and related method are disclosed for controlling condensation in a space. The system includes a fan and a sensor for sensing an environmental condition, such as temperature, humidity, or both. For instance, the sensors may sense an air temperature that is used to estimate or predict a surface temperature of an object within the room. The system also includes a controller capable of receiving controlling the fan based on the surface temperature. The system may additionally include a heater and/or a damper for transferring outside air into the space, either of which may be controlled by the controller based on the measurements.

Abstract: A system for controlling thermal comfort in a space is provided with a variable mode of operation. The system may include a conditioner for conditioning air in the space, and a sensor for measuring a temperature in the space. A controller is provided for controlling the conditioner based on the temperature sensed by the sensor, and a fan for circulating air within the space is regulated based on the temperature sensed by the sensor. A related system for controlling a fan based on height is also provided, as is a system and method for easily and efficiently determining the height of a fan using a simple camera, such as one on a “smart” phone. A further aspect pertains to a controller, such as for example a portable handheld device, having a user interface adapted for suggesting an increase in a set point temperature of a thermostat based on the selected speed of the fan.

Abstract: A light pipe for distributing light from a light source within a space, comprises a first portion adapted for receiving light from the light source and directing the light along an internal path in a first direction; a second portion adapted for receiving and distributing light received by the first portion from the light source in the first direction into the space; and a third portion intermediate the first and second portions, wherein the third portion is adapted for distributing light to the space in a second direction generally transverse to the first direction. The first portion may comprise a band, a lens, or both. Related aspects and methods are also disclosed.

Abstract: A fan may be designed for the strategic diversion of moisture through or around a housing enclosing a controller and/or a motor. The enclosure may include one or more paths for directing moisture away from the controller or the motor. For instance, the housing may include a gap between a support structure and the housing for preventing moisture from entering the housing. The housing may also include a hollow structure for directing fluid through the housing. Additionally, the housing may include one or more channels, raised walls, gutters, and shields for preventing fluid, such as liquid water, from entering an enclosure for the controller or motor.

Abstract: A fan mounting assembly has a mount, a ball member, and a support. The support is disposed within a vertical opening of the ball member and is coupled to the ball member. The mounting assembly may further comprise a wedge driven between an interior surface of the ball member and an exterior surface of the support in order to prevent movement of the support within the ball member. The mount has a mounting portion and a socket portion. The socket portion has a tapered interior surface. The tapered surface may have a constant angle. The ball member and support are disposed within the socket portion such that an outer surface of the ball member rests upon the tapered surface of the socket portion. The tapered surface may have features configured to prevent rotation of the ball member within the socket portion.

Abstract: A fan comprises a rotatable hub, a plurality of fan blades coupled with the hub, and a plurality of air fences coupled with the fan blades. Each fan blade has a free end and an opposite end secured to the hub. The air fences are positioned at selected locations along the length of the fan blades, between the ends of the fan blades. Each air fence includes a fin, which may extend upwardly or downwardly from the fan blade. Each air fence may be formed of a resilient material and may be configured to allow the air fence to be snapped onto a fan blade. Each air fence may define an opening through which a fan blade may be inserted. One or more surfaces of the air fence may be contoured to complement a surface contour of an airfoil shaped fan blade.

Abstract: A resilient hub assembly comprises a top plate, bottom plate, central hub, and outer spars. The central hub is coupled between the top plate and the bottom plate. The outer spars are coupled between the top plate and the bottom plate, and the outer spars are positioned in a circular arrangement about a common longitudinal axis of the top plate and the bottom plate. The resilient hub assembly is configured to be flexible. The top plate and/or the bottom plate may comprise cutouts, and/or the outer spars may be positioned as to allow a gap between the central hub and the outer spars to promote flexibility.

Abstract: A light fixture may include one or more light sources and one or more lenses for manipulating light provided by the light sources. The lenses may manipulate the direction of the light, light wavelength, dispersion pattern, or any other quality of the light. The lenses may be slidably removable from the light fixture to provide for easy exchange of one lens for another. This exchange of one lens for another may provide for rapid and easy changes to the light dispersion from the light fixture without requiring manipulation of the light sources themselves, especially in the case of exchanging a first lens with a first quality for a second lens with a second, different quality. In addition, a method of servicing the light fixture may include the provision of alternate lenses based on predetermined factors such as time, light degradation, environment of use, and the occurrence of specified events.
