Abstract: An LED-based light for replacing a conventional fluorescent tube in a fixture is provided. The LED-based light includes an elongate light transmitting rod defining a bore and at least one LED positioned at one or both ends of the rod and oriented to produce light longitudinally into a portion of the rod radially outward of the bore. At least one connector is physically coupled to an end of the rod and electrically coupled to the at least one LED. The at least one connector is adapted for physical and electrical connection to the fixture. In operation, the directional light produced by the at least one LED is dispersed by way of reflection, refraction, and/or diffusion while traveling longitudinally through the rod to reduce the appearance of bright spots.

Abstract: A lighting fixture having at least one internal processor and at least one fixed element to which controllable moving elements are rotatably fastened, one moving element having at least one light source that generates a beam of light. Information concerning positions of moving components in a lighting fixture is automatically achieved. Correct position indication at start up is obtained without moving the components to their end stops for finding set points for step motors by the provision of at least one absolute encoding device, which encoding device indicates the angular movement of a first input axel in relation to the encoding device, which absolute encoding device has a gearbox with a second internal axel, which first input axle drives a first toothed timing wheel, intermeshing with a second toothed timing wheel that rotates the second axel with a angular velocity different from the angular velocity of the first input axle.

Abstract: The present invention relates generally to a roof clamp and, more specifically, to a plastic clamp that removable secures itself between shingles to attach a holiday decoration to the roof. The present roof clamp comprises a textured, rectangular backplate that is pushed under adjacent shingles. Two prongs extend from a center portion of the backplate such that they travel between the two adjacent shingles. A rectangular front plate is hingedly attached to the back plate along their lower lengths. The two prongs travel through two corresponding apertures on the front plate to lockingly engage the roof clamp in place by means of a catch release. A narrow plastic hook extends from the lower side of the backplate. A gripping prong is hingedly attached to the hook at its terminal end. The gripping prong is capable of rotating such that it can be manipulated to reconcile with and grasp the rigid angle of the decorative element it is holding.

Abstract: Embodiments of this invention provide an enclosure for an LED circuit board. The enclosure is manufactured from a flame resistant material and includes LED apertures through which LEDs mounted on an LED circuit board may pass. The enclosure is designed to be positioned on the LED circuit board so that, when so positioned, the LEDs extend at least partially through the LED apertures in the enclosure. When the enclosure is positioned on the board, portions of its lower surface contact the upper surface of the board. Various fixation/retention methods may be used to retain the enclosure in position relative to the circuit board. It is preferable that such methods allow for the separation of the enclosure from the board.

Abstract: An electronic visual display system with an integrated general lighting system including an electronic visual display having a housing and one or more lighting devices integrated therewith to provide light to one or more spaces external to the electronic visual display housing. The lighting devices have an independent on and off state which allows for the lighting devices to be in the on state independent of the on and off state of the electronic visual display. The lighting devices provide a relatively constant and user selectable color and level of light output.

Abstract: A lighting system comprises a housing suitable for mounting to a structural unit. The housing includes a plurality of enclosure panels. At least two light-bearing members are moveable relative to the housing and are pivotally coupled one to another. A pair of actuators are moveable in opposing directions, one of the light-bearing members being coupled to one of the actuators and an other of the light-bearing members being coupled to an other of the actuators. Movement of the actuators relative to one another results in pivotal movement of the light-bearing members relative to one another, causing an end of each light-bearing member to move further from or closer to the housing.
