20090277794 | DIMENSIONAL CONTROL IN ELECTROFORMS - A method includes placing a conductive mold in a first bath of electroforming solution, the solution including metal and having a selected temperature. A current is provided to the electroforming solution so that metal deposits onto the mold, thereby forming an electroformed element on the mold, the electroformed element and the mold being a composite assembly. The method further includes removing the composite assembly from the electroforming solution and transferring the composite assembly to a second bath having the same selected temperature. Thereafter, the electroformed element is separated from the mold while the composite assembly is in the second bath. | 11-12-2009 |
20100168894 | SYSTEM AND METHOD FOR DESIGNING A DIE TO YIELD A DESIRED COATING UNIFORMITY - In one embodiment, a computer implemented system and method for selecting dimensions of a die is disclosed. The method may include prompting a user to select a coating uniformity required to produce a particular coated product with the die. The user may also be prompted to select a slot height of the die. In some embodiments, the user may specify a value for one or more dimensions of the die. The method may then determine the total indicated run-out (TIR) of the coated product as a function of the dimensions of the die not having a user specified value. In certain embodiments, the method provides a thermal treatment process for reducing the number of finishing (e.g., grinding) cycles needed to produce a desired die flatness. In another embodiment, a computer implemented method for designing a coating die to achieve a desired coating uniformity with a particular coating fluid having a specified rheological characteristic is disclosed. | 07-01-2010 |
20120139403 | SOLID STATE LIGHT WITH OPTICAL GUIDE AND INTEGRATED THERMAL GUIDE - A solid state light having a solid state light source such as LEDs, an optical guide, and a thermal guide. The optical guide is coupled to the light source for receiving and distributing light from the light source, and the thermal guide is integrated with the optical guide for providing thermal conduction from the solid state light source and dissipating heat through convection and radiation for cooling the light. The optical guide can be tapered to enhance the efficiency of light distribution. The thermal guide can have an external shell connected with internal fins, and the external shell can have a reflective coating to provide for a back reflector behind the optical guide. | 06-07-2012 |
20130155719 | LIGHTGUIDE AS LUMINAIRE - A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light. The shape can also be used to create a particular pattern of the extracted light. | 06-20-2013 |
20130257278 | ELECTRICAL CONNECTORS FOR SOLID STATE LIGHT - A light having integrated light and thermal guides and separable electrical connectors. The light has a base for connection to a power supply, a light circuit electrically connected with solid state light sources such as LEDs, and a driver circuit for receiving power from the power supply and providing power to drive the light sources. A light guide is coupled to the light sources for receiving and distributing light from the light sources, and a thermal guide is integrated with the light guide for providing thermal conduction from the light source for cooling the light. The separable connectors include a first connector for providing an electrical connection between the driver circuit and light circuit, a second connector for providing an electrical connection between the power supply and driver circuit, and a third connector for providing a ground connection to the driver circuit. | 10-03-2013 |
20130301268 | SOLID STATE LIGHT WITH ALIGNED LIGHT GUIDE AND INTEGRATED VENTED THERMAL GUIDE - A light with integrated light and thermal guides, and having solid state light sources such as LEDs. The light guide includes a material having a first surface and a second surface opposite the first surface and forming an interior volume. The light guide is coupled to the LEDs for receiving and distributing light from them through the first surface, and the light is transported through the light guide until the light is extracted from the first or second surface. The light guide can include alignment features such as fiducials that mate with a base. The thermal guide is contained within the interior volume and integrated with the light guide for providing thermal conduction from the LEDs for cooling the light. The thermal guide can be vented to provide for internal cross flow of air for the cooling. | 11-14-2013 |
20140340927 | LIGHTGUIDE AS LUMINAIRE - A lightguide functioning as a luminaire. The luminaire includes at least one solid state light source, such as an LED, and a lightguide configured to receive light from the solid state light source. Light from the light source is coupled into the lightguide and transported within it by total internal reflection until the light exits the lightguide. A shape of the lightguide causes and directs extraction of the light, and can also be used to create a particular pattern of the extracted light. Such shapes include linear wedges and twisted wedges. Optical films can be included on the light input and output surfaces of the lightguide. | 11-20-2014 |
20150098128 | Optical Component Array - The present disclosure provides an optical component array and method of making an optical component array that can include a plurality of optical components useful for projection devices or other optical devices. The optical component array can be fabricated such that individual optical components having several elements can be assembled in a massively parallel manner and then singulated as individual optical components, and can result in a large reduction in manufacturing cost. | 04-09-2015 |
