A transfer film comprising a base film, a transfer layer, and a transfer auxiliary layer formed between the base film and the transfer layer so as to be in contact with at least the transfer layer, this transfer auxiliary layer having a melting point or a glass transition temperature lower than that of the transfer layer, wherein at least a portion of the transfer layer can be thermally transferred onto a substrate.

A novel system and method for achieving accurate readings of the rotational speed, number of revolutions and direction of rotation of a utility system. More specifically, a system and method for retrofitting existing utility meters with a lightweight tape, having contrasting sections of reflective and non-reflective material applied thereto, which is read by optical sensors as the lightweight tape passes by with the revolutions of the disk of the utility meter. Additionally, the system and method detects unauthorized use of the utility or tampering with the utility meter and its functions.

The present invention is a robust LED display module for use in an electronic sign which display module includes a metallic housing, a heat conductive interface panel, an LED circuit board and LEDs, and a metallic mask arranged in intimate contact and association therewith, and which components operate synergistically in concert with each other in order to evenly distribute, reduce and dissipate heat along, about and within the structure of the present invention. Display uniformity is provided by the use of major metallic structures in order to prevent warpage and to protect the geometric integrity of the LED display module.

The specification and drawings present a new apparatus and method for designing and using display devices with integrated backlight layer structure utilizing separate color diffractive out-coupling (e.g., diffraction out-coupling). A lower substrate of the display can be used to integrate the backlight component (or the backlight layer structure), thus enabling a thin module with the integrated backlighting.

An example of this light bulb has a light emitting element (which may be an LED array) mounted on a circuit board. The circuit board is mounted on one end of a heat-conducting frame. An Edison screw or other suitable connector, for attaching the light bulb electrically and mechanically to a receptacle, is mounted on the other end of the frame. A transparent phosphor-coated ball has a flat chord face optically bonded to said array. A light-permeable globular enclosure is mounted on the frame, surrounding the ball and both homogenizing the white light output of the bulb but also concealing the yellowing unlit appearance of the remote phosphor ball centrally located within it.

A transparent conductor including a conductive layer coated on a substrate is described. More specifically, the conductive layer comprises a network of nanowires that may be embedded in a matrix. The conductive layer is optically clear, patternable and is suitable as a transparent electrode in visual display devices such as touch screens, liquid crystal displays, plasma display panels and the like.

Illumination devices utilized within detachable illumination systems include a light source including a substantially planar light-emitting surface and an optical rod or optical taper disposed proximate to the substantially planar light-emitting surface to optically couple the optical rod and the substantially planar light-emitting surface.

A kit apparatus has a molded support card holding a plurality of film sheets each having an adhesive layer on one side, a spray bottle containing a cleaning and activating solution enabled for activating the adhesive layers of the film sheets, and a squeegee. The film sheets are secured within a first pocket in the support card, the squeegee secured within a second pocket in the support card, and the spray bottle is secured within a recess in the support card. Plural tabs extend over the recess for holding the spray bottle securely within the recess.

Lighting apparatus and methods employing LED light sources are described. The LED light sources are integrated with other components in the form of a luminaire or other general purpose lighting structure. Some of the lighting structures are formed as Parabolic Aluminum Reflector (PAR) luminaires, allowing them to be inserted into conventional sockets. The lighting structures display beneficial operating characteristics, such as efficient operation, high thermal dissipation, high output, and good color mixing.

Embodiments described herein provide optical systems that can mix colors to produce illumination patterns having a large area with uniform color. One embodiment of an optical system can include a set of optical units that each produces an illumination pattern with uniform color and intensity. The optical units are spaced so that the individual illumination patterns overlap to create an overall illumination pattern with an overlap area. In the overlap area, the colors emitted by the individual optical units mix to create a desired color. Embodiments of optical systems can provide beam control so that the optical units emit a high percentage of light in beam.

A light emitting assembly having a first light source and a second light source. The first and second light sources are oriented such that when the first and second light sources emit light, light emitted from the first and second light sources overlaps and is capable of forming white light. The light emitted from the first light source exhibits color coordinates different from the light emitted from the second light source. Also disclosed is a license plate illuminator having an LED device capable of emitting white light.

A LED is covered with an electroconductive layer, and a luminescent layer is deposited on the electroconductive layer by electrophoresis. The conductivity of the electroconductive layer is chosen to be such that the layer can be used as one of the electrodes during the electrophoresis, while the LED is not short-circuited by the electroconductive layer during normal operation.

An exemplary hollow stylus-shaped structure is disclosed, including a hollow column spacer formed over a base layer and a hollow cone spacer stacked over the hollow column spacer, wherein the hollow cone spacer, the hollow column spacer, and the base layer form a space, and sidewalls of the hollow cone spacer and the hollow column spacer are made of silicon-containing organic or inorganic materials.

LED light bulbs include openings in base or cover portions, and optional forced flow elements, for convective cooling. Thermally conductive optically transmissive material may be used for cooling, optionally including fins. A LED light engine may be fabricated from a substrate via planar fabrication techiques and shaped to form a substantially rigid upright support structure. Mechanical, electrical, and thermal connections may be made between a LED light engine and a LED light bulb.

This invention provides a vapor-tight luminaire that maintains a moisture-proof, sealed lower housing for the light-producing lamps (fluorescent lights, LED arrays, etc.) while isolating the electronic components in a separate, upper housing that is spaced apart from, and largely thermally isolated from, the lamps. The lamp housing comprises a unitary non-penetrated tubular lens with one or more removable end caps, sealed by gaskets. The lamp assembly is slidably mounted within the lower housing so that it is readily removable and replaceable with another assembly of the same or different type. The electronics in the upper housing is readily accessible and replaceable by removing a top cover that encloses a three sided channel member. The upper housing is metal and desirably enhances heat exchange with the environment. The two housings are held together by a pair of opposing end cap structures that include a housing end and a removable end cap. The housing end includes an upper plate that is fastened against an adjacent end of the upper housing's channel member. This compresses gaskets that stand between the respective ends of the lens and a lower ring on each housing end. The electronics of the upper housing is interconnected via a wiring harness connector to an end connector in on the lamp assembly. The wiring harness passes between the two housings free of penetration of the lens.
