Abstract:
A security monitoring system/method implementing distributed Internet-based environmental monitoring and control is disclosed. The system utilizes a smart gateway power controller (SGPC) configured for new/retrofit installation into electrical power distribution networks to allow controlled connection of an AC power source to a customer load device under direction of local or remote Internet direction. The SGPC may also be configured with sensors to detect motion, audio, video, visual images, smoke, carbon monoxide, carbon dioxide, light/darkness, and other environmental data. The SGPC may be configured using a local web-based graphical user interface (GUI) to relay collected sensor information to a remote web browser hosted on a remote computing device. The GUI may incorporate a configuration/setup interface allowing mapping of sensor data to information associated with the sensor location and triggered security reports to occur based on collected sensor data.

Die Erfindung stellt eine Schalteinheit für einen über einen Phasenleiter mit AC-Spannung betrieben elektrischen Verbraucher, insbesondere für eine Retrofit LED-Lampe, mit wenigstens einem Betätigungselement, wobei das Betätigungselement dazu ausgelegt ist, die Verbindung zwischen Phasenleiter und Verbraucher über zwei parallele Zweige herzustellen, wobei je nach Stellung des Betätigungselements entweder eine direkte Verbindung über den ersten Zweig oder eine Verbindung über eine Diode über den zweiten Zweig hergestellt wird.
Abstract:
Disclosed herein is a remotely adjustable lighting system with security features. The lighting system includes a lamp (e.g., luminaire) which carries solid-state light sources and a sensor. The solid-state light sources emit visible light at an adjustable output intensity. The sensor is responsive to line-of-sight wireless signals, and the lamp increases and decreases the output intensity of the light sources in response to output signals of the sensor. The lamp provides security features by selectively accepting and rejecting instructions carried by the line-of-sight wireless signals to vary the output intensity of the light sources.
Abstract:
A light bulb includes a light guide, light source, and housing. The light guide is configured as an open-ended hollow body surrounding an internal volume and defining a longitudinal axis. The light guide has inner and outer major surfaces. The light source is configured to edge light the light guide. The housing is at one end of the light guide. In one embodiment, fins extend from the housing adjacent the outer major surface, each fin separated from the outer major surface by an air gap to allow air flow between the fin and outer major surface. In another embodiment, a heat sink is disposed in the internal volume and configured as a hollow body with a branched cross section. Each branch extends outward from a common center and defines an air flow channel that terminates in an orifice aligned with a respective through-slot of the light guide.
Abstract:
A lighting system includes a controller that is configured to provide thermal management for the lighting system by distributing excess energy in the lighting system through multiple power dissipation circuits. In at least one embodiment, the lighting system is a phase cut compatible, dimmable lighting system having one or more light sources selected from a group consisting of at least one light emitting diode and at least one compact fluorescent lamp. In at least one embodiment, the controller is configured to control the plurality of power dissipation circuits in accordance with a thermal management strategy to dissipate the excess energy in the phase cut compatible, dimmable lighting system. The particular thermal management strategy is a matter of design choice. The power distribution circuits include two of more of: a controlled switch path power dissipation circuit, a controlled link path power dissipation circuit, and a controlled flyback path power dissipation circuit.
Abstract:
A dimmable ballast circuit for a compact fluorescent lamp controls the intensity of a lamp tube in response to a phase-control voltage received from a dimmer switch. The ballast circuit comprises a phase-control-to-DC converter circuit that receives the phase control voltage, which is characterized by a duty cycle defining a target intensity of the lamp tube, and generates a DC voltage representative of the duty cycle of the phase-control voltage. Changes in the duty cycle of the phase control voltage that are below a threshold amount are filtered out by the converter circuit, while intentional changes in the duty cycle of the phase control voltage are reflected in changes in the target intensity level and thereby the intensity level of the lamp tube.
Abstract:
A hybrid lamp apparatus is presented having a primary lamp circuit with a CFL and an electronic ballast, as well as a Halogen or incandescent secondary lamp circuit with a control circuit that shuts off the secondary lamp a time period after powerup, where the secondary lamp time period varies according to the amount of time the apparatus was previously unpowered.
