20130135879 | THERMALLY ISOLATED HEAT SINK FOR LED LIGHTING - A system for protecting a heat-sensitive component in an LED lamp from overheating. The system including: a heat-generating component, a heat-dissipating component thermally coupled to the heat-generating component, a heat-sensitive component electrically connected to the heat-generating component, and a heat-isolating element for thermally isolating the heat-generating component and the heat-sensitive component. | 05-30-2013 |
20130113458 | LED LAMP DRIVER IDENTIFICATION - The type of an LED power driver (i.e., a magnetic transformer or an electronic transformer) is determined by manipulating the AC voltage produced by the power driver so that it may be analyzed and the type of power driver reliably determined. In various embodiments, a system for detecting an AC power supply type includes a circuit for monitoring a negative half or a positive half of an output voltage of the AC power supply and an analyzer for determining the AC power supply type based at least in part on a presence or absence of an envelope in the monitored output voltage. | 05-09-2013 |
20120119679 | EXTERIOR ILLUMINATION AND EMERGENCY SIGNALING SYSTEM AND RELATED METHODS - LEDs that provide street illumination are used to create emergency signals. This facilitates simple retrofitting of existing streetlighting infrastructure. In one embodiment, a streetlight comprises an LED set that itself comprises or consists of a plurality of LEDs collectively producing a white light output. The streetlight also includes a receiver for receiving a signal of an alarm condition, and a controller for (i) disabling the LED set during a daylight period, (ii) maintaining the normal operating mode during a lighting period distinct from the daylight period, and (iii) in response to the alarm condition detected by the receiver, de-activating at least one of the LEDs to produce a non-white (e.g., red or amber) output signaling the alarm condition | 05-17-2012 |
