Patent number: 7931390Abstract: A jacketed light emitting diode assembly is provided, which includes a light emitting diode, a lens body containing a semiconductor chip and a set of positive and negative contacts exiting said lens body from a base portion. An electrical wire set of first and second electrical wires are connected to the positive contact and the negative contact, respectively. An integrally molded plastic jacket is provided at the base portion of the lens body around said positive and negative contacts and connection points between the contacts and the wire set to provide a seal at the base portion and at the connection points against moisture and airborne contaminants, whereby a portion of the first and second electrical wires project from the jacket to define bendable contacts for providing an electrical connection with a lamp husk. An optional light transmissive cover may further be provided.Type: GrantFiled: September 26, 2008Date of Patent: April 26, 2011Assignee: Fiber Optic Designs, Inc.Inventors: Mark R. Allen, David Allen

Publication number: 20100095324Abstract: Advertisements can be paired based on their context to achieve increased advertising effectiveness that might not be able to be achieved without the pairing. The advertisements can be paired based on a user's preferred context, which includes an attribute of one of the advertisements. For example, a conditional advertisement can be paired with a scheduled advertisement based on an industry type, the length of the other advertisement, or some other characteristic. Each characteristic can be given a weight, to aid in pairing determinations. The effectiveness of the pairing can be tracked, and the context can be iteratively modified based on the measured effectiveness of the advertising campaign. Pairing can be performed without identifying other advertisers, even though weighting factors may take a sponsor's identity into account. Pairing can be constrained by a master schedule and by a maximum allowed number of conditional spots.Type: ApplicationFiled: July 31, 2009Publication date: April 15, 2010Applicant: CLEAR CHANNEL MANGEMENT SERVICES, INC.Inventors: Bobbi Denise Schuster, Matthew Ferry, John Fulbright, David C.

Patent number: 7679292Abstract: An LED light string employs a plurality of LEDs wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage or rectified AC input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. The same method that apply to matching the sum of the LED lamps (VAC values) to the AC input, or applied voltage in an AC circuit apply to matching the sum of the LED lamps (VP values) to the full-wave or half-wave rectified AC (VP) voltage applied. Filtering capacitors may also be employed.Type: GrantFiled: October 26, 2006Date of Patent: March 16, 2010Assignee: Fiber Optic Designs, Inc.Inventors: David Allen, Mark R. Allen

Patent number: 7220022Abstract: A jacketed light emitting diode assembly is provided, which includes a light emitting diode including a set of positive and negative contacts, and a lens body containing a semiconductor chip and end portions of the contacts. An electrical wire set of first and second electrical wires are connected to the positive contact and the negative contact, respectively. A light transmissive cover receives the lens body, and has an opening through which at least one of the contact set and the electrical wire set passes. An integrally molded plastic jacket at the opening of the light transmissive cover provides a seal at the opening against moisture and airborne contaminants. A waterproof light string including one or more of the jacketed light emitting diode assemblies is also provided, as are related methods.Type: GrantFiled: February 21, 2006Date of Patent: May 22, 2007Assignee: Fiber Optic Designs, Inc.Inventors: Mark R.

Patent number: 6933707Abstract: Field Effect Transistors (FETs) are used to regulate current in a light emitting diode (LED). FETs are fundamentally voltage driven devices, where output current is governed by junction voltage. Since junction voltage can be controlled with little or no support circuitry, FETs present a solution to current regulation where cost, complexity, and perhaps even size are important.Type: GrantFiled: June 27, 2003Date of Patent: August 23, 2005Assignees: Luxidein Limited, Fiber Optic DesignsInventor: Mark R.

Patent number: 6830358Abstract: An LED light string employs a plurality of LEDs wired in block series-parallel, where the one or more series blocks, each driven at the same input voltage as the source voltage (110 VAC or 220 VAC), are coupled in parallel. The LED light string interfaces to the source voltage using a common household plug; it may also include a corresponding common, household socket, coupled in electrical parallel, to enable multiple light strings to be connected to each other from end to end. In order to directly drive a network of diodes without current-limiting circuitry, the voltage of each series block of diodes must be matched to the input source voltage. This voltage matching requirement for direct AC drive places fundamental restrictions on the number of diodes on each diode series block, depending on the types of diodes used. For the voltage to be “matched,” in each series block, the peak input voltage must be less than or equal to the sum of the maximum diode voltages for each series block.Type: GrantFiled: September 16, 2002Date of Patent: December 14, 2004Assignee: Fiber Optic Designs, Inc.Inventor: Mark R.

Moreover, each LED may have internal circuitry to provide for intermittent on-off blinking and/or intermittent LED sub-die color changes.Type: ApplicationFiled: September 9, 2003Publication date: March 11, 2004Applicant: FIBER OPTIC DESIGNS, INCInventor: Mark R.

Patent number: 6072280Abstract: An LED light string employs a plurality of LEDs wired in a series-parallel block. Further, each series-parallel block may be coupled in parallel, the parallel connection coupled across a supply voltage through an electrical interface. LEDs of the light string may comprise either a single color LED or an LED including multiple sub-dies, each sub-die of a different color. LED series-parallel blocks of the light string may be operated in continuous, periodic or pseudo-random state. The LED light string may provide polarized connectors to couple LED light strings end-to-end and in parallel with the supply voltage. The electrical interface may have one or more parallel outputs and a switch so as to operate multiple LED light strings in continuous, periodic or pseudo-random states. The LED light string may be adapted so as to employ LEDs of different drive voltages in each series section of the series-parallel block.Type: GrantFiled: August 28, 1998Date of Patent: June 6, 2000Assignee: Fiber Optic Designs, Inc.Inventor: Mark R.
