| 20110273890 | VENTILATED LED OPTICS - In accordance with certain embodiments, an illumination device includes a light-emitting diode and a light-guiding optical component comprising a channel therethrough. | 11-10-2011 |
| 20120171881 | PERMANENT CONVERSION ADAPTER FOR LIGHTING FIXTURES - A permanent adapter for incandescent lighting fixtures can removably receive LEDs but cannot itself be removed from the fixture. | 07-05-2012 |
| 20120194098 | BRIGHTNESS CONTROL FOR LIGHTING FIXTURES - A brightness controller determines a dimmer setting and adjusts brightness of a light source according to the dimmer setting. | 08-02-2012 |
| 20120206062 | TIME-DOMAIN REDUCTION OF FLICKER AND POWER CONSUMPTION IN LED LIGHTING - In accordance with certain embodiments, a power signal for driving an LED lighting system is analyzed on a timeslice basis, and the signal is adjusted (e.g., on a timeslice basis) to compensate for deviations therein. | 08-16-2012 |
| 20120268013 | DYNAMIC-HEADROOM LED POWER SUPPLY - A voltage level supplied to power a plurality of LED light fixtures is dynamically adjusted to control the headroom of the voltage level. The current drawn by at least one of the plurality of LED light fixtures is monitored, and the voltage is increased from zero until the monitored current reaches its maximum. | 10-25-2012 |
| 20120268030 | LED DRIVER HAVING CONSTANT INPUT CURRENT - Power consumed by an LED driver may be reduced by drawing, from an electronic transformer or dimmer, an input current that is constant over a plurality of input voltages. Power derived from the constant input current is provided to the LED driver. | 10-25-2012 |

| 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 |
| 20120162431 | METHODS AND SYSTEMS FOR MONITORING TRAFFIC FLOW - In accordance with certain embodiments, a method of monitoring traffic includes capturing a plurality of time-separated images of a moving vehicle, calculating a velocity of the vehicle based on at least two of the images, and obtaining vehicle-identifying information from at least one of the images or transmitting a notification to a central location if the velocity is greater than a threshold velocity. | 06-28-2012 |

| 20120062120 | THERMAL FOLDBACK CIRCUIT WITH DIMMER MONITOR - A thermal foldback circuit protects a lamp circuit component from overheating by limiting power to the lamp in response to an over-temperature condition. The amount of limiting is adjusted based at least in part on an input from an external power-reduction source, such as a dimmer. | 03-15-2012 |
| 20120062141 | VARIABLE-IMPEDANCE LOAD FOR LED LAMPS - In various embodiments, a startup circuit for a low-voltage-lighting electronic transformer includes a low-impedance output circuit. At the beginning of an AC signal cycle, the low-impedance output circuit presents a low-impedance path to the output of the transformer, thereby causing a surge of current in the transformer and initiating oscillation therein. | 03-15-2012 |

| 20100103688 | VEHICLE LIGHT - Lights for attachment to a vehicle including a first illuminating means directed substantially perpendicular to a surface plane of the light and a second illuminating means directed substantially parallel with the surface plane of the light. The second illuminating means may be mounted solely within a lower hemisphere of the light. The light may also include a covering hood. | 04-29-2010 |
| 20120146539 | JITTER DETECTION AND COMPENSATION CIRCUIT FOR LED LAMPS - A power signal driving an LED is measured to determine a characteristic (e.g., a power level) of the power signal. The characteristic is compared to the power signal's history and any deviation is detected. If the source of the deviation is determined to be jitter, the deviation is compensated for. | 06-14-2012 |
