摘要： Solid state lamps and bulbs comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, regions or layers which are positioned separately or remotely with respect to the light source, and a separate diffuser. These are arranged on a heat sink in a manner that allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omni-directional emission pattern, even with a light source comprised of a co-planar arrangement of LEDs. Additionally, this arrangement allows aesthetic masking or concealment of the appearance of the conversion regions or layers when the lamp is not illuminated. Various embodiments of the invention may be used to address many of the difficulties associated with utilizing efficient solid state light sources such as LEDs in the fabrication of lamps or bulbs suitable for direct replacement of traditional incandescent bulbs. Embodiments of the invention can be arranged to fit recognized standard size profiles such as those ascribed to commonly used lamps such as incandescent light bulbs, while still providing emission patterns that comply with ENERGY STAR® standards.

摘要： Solid state lamp or bulb structures are disclosed that can provide an essentially omnidirectional emission pattern from directional emitting light sources, such as forward emitting light sources. The present invention is also directed to lamp structures using active elements to assist in thermal management of the lamp structures and in some embodiments to reduce the convective thermal resistance around certain of the lamp elements to increase the natural heat convection away from the lamp. Some embodiments include integral fans or other active elements such as diaphragm-pump type active cooling elements, that move air over the surfaces of a heat sink, while other embodiments comprise internal fans or other active elements that can draw air internal to the lamp. The movement of the air over these surfaces can agitate otherwise stagnant air to decrease the convective thermal resistance and increasing the ability of the lamp to dissipate heat generated during operation.

摘要： An LED lamp or bulb is disclosed that comprises a light source, a heat sink structure and a remote phosphor carrier having at least one conversion material. The phosphor carrier can be remote to the light sources and mounted to the heat sink so that heat from the phosphor carrier spreads into the heat sink. The phosphor carrier can have a three-dimensional shape, and can comprise a thermally conductive transparent material and a phosphor layer, with an LED based light source mounted to the heat sink such that light from the light source passes through the phosphor carrier. At least some of the LED light is converted by the phosphor carrier, with some lamp embodiments emitting a white light combination of LED and phosphor light. The phosphors in the phosphor carriers can be arranged to operate at a lower temperature to thereby operate at greater phosphor conversion efficiency and with reduced heat related damage to the phosphor. The lamps or bulbs can also comprise a diffuser over the phosphor carrier to distribute light and to conceal the phosphor carrier.

摘要： The co-browsing system described enables participants to share controlled content during a co-browsing session. A first participant's input on a web page may be collected and transferred to a second participant's computing device. The browser in the second participant's computing device, which is displaying the same web page, may receive the first participant's input and be manipulated by the first participant's input. Consequently, the participants may share a web-browsing experience while they jointly navigate web-related content at the same time, including the content and their activities on web pages, as if they are interacting with the web page on the same screen. Such controlled content co-browsing occurs in a system which has a repository of controlled content items and customer relationship management (CRM) information.

摘要： Standardized photon building blocks are packaged in molded interconnect structures to form a variety of LED array products. No electrical conductors pass between the top and bottom surfaces of the substrate upon which LED dies are mounted. Microdots of highly reflective material are jetted onto the top surface. Landing pads on the top surface of the substrate are attached to contact pads disposed on the underside of a lip of the interconnect structure. In a solder reflow process, the photon building blocks self-align within the interconnect structure. Conductors in the interconnect structure are electrically coupled to the LED dies in the photon building blocks through the contact pads and landing pads. Compression molding is used to form lenses over the LED dies and leaves a flash layer of silicone covering the landing pads. The flash layer laterally above the landing pads is removed by blasting particles at the flash layer.
