20120112641 | LED NIGHT LIGHT/LED EMERGENCY LIGHT - An LED fixture is disclosed. The fixture includes an LED array having at least one LED, a first LED driver which is a lower intensity driver and a second LED driver which is a higher intensity driver. The LED drivers and the LED array are electrically connected in parallel to each other and the LED drivers are capable of simultaneously and continuously supplying power to each LED in the LED array. | 05-10-2012 |
20120299506 | VARIABLE OUTPUT MODULE AND METHOD FOR ELECTRICAL SIGNAL OUTPUT - A variable output module provides accurate full range dimming or adjustment of power output. The variable output module utilizes the characteristics of an AC or other periodic signal rather than its power output to accurately determine the level of dimming a user desires. In this manner, the variable output module provides accurate full range dimming without the need for calibration to specific AC signals. The variable output module can detect the period of an AC signal allowing the driver to be used with various frequencies without the need for calibration. In one or more embodiments, the driver compares the pulse widths of a dimmed AC signal to the period of the AC signal to determine the desired level of dimming. | 11-29-2012 |
20130207548 | LIGHT EMITTING DIODE AND INTEGRATED PACKAGE THEREFOR - An improved LED provides power efficient lighting while accepting a wide range of input voltages. The improved LED may comprise a controller that may measure a voltage, current, or other characteristics of input power and modify operation of the improved LED accordingly, such as to accept significantly more voltage or significantly less voltage while providing consistent light output. This allows light bulbs or other lighting to be easily manufactured with the improved LED. The improved LED may comprise the controller and one or more LED dies enclosed by a substrate and lens structure. Depending on the configuration of the controller, the improved LED may also provide time, temperature, and other measurement/response functions to help ensure consistent light output. | 08-15-2013 |
20130271983 | INTEGRATED, WATER TIGHT, LED ARRAY HOLDER ASSEMBLY - The present disclosure relates to a Chip on Board (COB) Light Emitting Diode (“LED”) array assembly that incorporates refractive optics, an electrical connection to the LED array, an environmental sealing of the LED array and interior optical chamber, and which includes an anti wicking breaker on the electrical pass through, and which is sealed against a modular heat sink. The assembly is separately removable for field maintenance. | 10-17-2013 |
20140028191 | LED DRIVER - Lighting systems are disclosed, including a multi-die LED array; and LED driver electronics, which include voltage regulating electronics which regulate rectified low voltage AC. The voltage regulating electronics include: booster electronics that sense rectified low voltage AC and boost the LVAC to a predetermined voltage for powering the multi-die LED; power factor correcting electronics that sense the AC current and AC voltage in the driver and control the booster electronics to further regulate the voltage, thereby providing power factor correction; and constant current electronics which sense one or both of current and voltage through the driver and control the booster electronics to further regulate the voltage, thereby providing substantially constant current to the multi-die LED array. | 01-30-2014 |
20140098530 | DIRECTIONALLY CONTROLLABLE STREET LAMP - A street lamp | 04-10-2014 |
20140120756 | LED CONNECTOR - Connectors for a lighting board are disclosed, adapted for receiving electrical energy from a power source, and via one or more conductive fasteners, both mechanically connecting a lighting board to a lighting frame and transmitting power from a power source | 05-01-2014 |
20140246986 | LED LIGHTING SYSTEM - A DC-powered LED lighting device and a lighting system using such devices are disclosed. A common AC/DC power supply is coupled to at least one electric main and provides power to the LED lighting devices at DC voltages that are higher than the peak voltage of the sine wave of the at least one electric main. | 09-04-2014 |
