20100135000 | LIGHT UNIT WITH INTERNAL POWER FAILURE DETECTION - A light unit that includes an internal power supply that may be used in the event of an external power failure to provide power to the light unit. In one aspect, the present disclosure provides a lighting apparatus, comprising (a) a power input configured to receive external power from an external power source; (b) a solid state light element that is interconnected to the power input; (c) a detection circuit interconnected to the power input and that, when power is not provided to the power input, measures input impedance at the power input and determines if there is a lack of external power; and (d) a back-up power source that is interconnected to the solid state light element and the power input and that provides power to the solid state light element when the light element is; not provided with power from the power input. | 06-03-2010 |
20100315813 | SOLID STATE LIGHT UNIT AND HEAT SINK, AND METHOD FOR THERMAL MANAGEMENT OF A SOLID STATE LIGHT UNIT - A lamp assembly manages thermal energy output from solid state lighting elements. An aspect of the present disclosure provides a lamp assembly that achieves enhanced cooling of light elements within the assembly. Enhanced cooling is achieved, in this aspect, by providing a lamp assembly including a heat sink having a plurality of thermo bosses protruding therefrom on a first side, and a plurality of heat sink fins on a second side. A printed circuit board is secured to the first side of the heat sink, and has a plurality of through holes that correspond to the size and locations of the thermo bosses, such that when the printed circuit board is secured to the heat sink, the thermo bosses extend into the through holes. | 12-16-2010 |
20100326523 | System and Method for Collecting and Optically Transmitting Solar Radiation - A solar power system includes solar panels placed below-grade and an optical section placed above-grade that collects solar radiation and transmits the solar radiation to the solar panels. The optical section may include optical components and a tracking mechanism. Photovoltaic material may be mounted to one or more surfaces below grade. The surfaces may have a reflective coating that reflects optical radiation that is not absorbed by photovoltaic material of the solar panels such that other solar panels receive the reflected light. | 12-30-2010 |
20110246146 | LIGHT UNIT WITH LIGHT OUTPUT PATTERN SYNTHESIZED FROM MULTIPLE LIGHT SOURCES - The present disclosure provides an LED based light unit that produces an output lighting pattern that meets desired lighting characteristics using a reduced number of LED elements. The present disclosure provides a number of point sources that are directed into a desired direction such that, when combined with other point sources, a synthesized light output is provided that minimizes the LED headcount. | 10-06-2011 |
20110299281 | SYSTEM FOR RETROFITTING AN EXISTING LIGHT FIXTURE WITH AN LED LUMINAIRE - An adapter plate is provided that fits an existing luminaire in place of an existing globe that mounts to the luminaire. A heat sink mates to the adapter plate and also houses a solid state light engine and associated electronics. The heat sink may provide an enclosed, protective volume for the associated electronics, such as a power supply for the solid state light engine. A globe mounting ring attached to the heat sink allows either an existing globe to be re-mounted or a new globe to be installed. | 12-08-2011 |
20120025711 | SOLID STATE OUTDOOR OVERHEAD LAMP ASSEMBLY - An outdoor overhead lamp assembly uses light emitting diodes to provide illumination for an area to be illuminated. The lamp assembly includes a unitary housing, which may be formed from a single casting. The housing includes mechanical mounting structure for mounting the housing to a mast arm. The housing includes an electrical compartment for housing electrical components and connections. Heat sink fins are formed on the integral housing that provide for thermal control of the electronic components and LED modules within the lamp assembly. The LED modules are mounted to aiming platforms within an optical compartment for the assembly. An external lens provides environmental protection for the LEDs and their individual lenses. The housing may also include structures for mounting decorative coverings or “skins” to accommodate different aesthetic requirements. | 02-02-2012 |
20140204577 | LIGHT UNIT WITH LIGHT OUTPUT PATTERN SYNTHESIZED FROM MULTIPLE LIGHT SOURCES - The present disclosure provides an LED based light unit that produces an output lighting pattern that meets desired lighting characteristics using a reduced number of LED elements. The present disclosure provides a number of point sources that are directed into a desired direction such that, when combined with other point sources, a synthesized light output is provided that minimizes the LED headcount. | 07-24-2014 |
